Not much more snow left

Noon Monday

As expected, the heaviest snows are over by midday.  Radar indications and model data confirm that we will see the snow fading away this afternoon.  But, the periods of heavy snow we saw this morning are over.  Light snow may accumulate another inch or two over the next 3-4  hours, but it should all be over around 5-6P.M.   Looks like snowfall totals will end on the lower side of my earlier estimates.

NOTE:  Heard local officials this morning say that it was too cold for salt to do any good.  So they weren’t salting the roads.  MOST OF THE TIME, that statement is correct.  But, salting between 9 A.M. and 3 P.M.  would do a lot of good even at 15 degrees.  Why?  APRICITY   (look it up and you’ll see why.  Apricity is also why Wind Chill temperatures are far from accurate during daytime hours.

Colder again tomorrow and Friday

Wednesday Afternoon

As it turned out, it wasn’t too difficult to get temperatures above 40.  Unfortunately the milder weather won’t last long.  A moisture-starved upper air disturbance has been passing over the Ohio Valley this afternoon.  All it could do moisture-wise was the clouds this afternoon.  They will fade away tonight.  But this system is also bringing us another shot of unseasonably cold air.  It won’t be as bad as Monday and yesterday, but should hold highs to the mid 30’s tomorrow and near 40 Friday.

It still looks like some rainy (and warmer) weather will arrive by the weekend.  A strong storm is taking shape over the southwestern U.S. and will provide us with at least 3 “waves” of energy before it exits our area.  First, the leading edge of this system will send a weak disturbance our way Saturday.  As often happens, the first surge of energy brings lots of moisture into the area but little, if any, precipitation.  This one looks the same way and if it does produce any rain it will be more likely over southern Indiana rather than Kentucky.  A lot more energy will be tied up in the second system, set to arrive Sunday.  This should bring lots of rain and temperatures rising to near 60 degrees.  Even a thunderstorm will be possible.  A third storm should arrive on Monday.  It’ll prevent any major temperature drop following system 2, but it should bring us some more rain.  Following that system, we’ll see temperatures dropping back to January levels (highs near 40) for a couple of days.

Polar Bear Stuff

Over the past few days, several world newspapers have been carrying stories about a “40% population decline in the past 10 years.”  Brings back Al Gore’s photoshopped picture  of a lonely polar sitting on a small chunk of sea ice with nothing but water anywhere to be seen.  It was the major talking point for his infamous declaration that polar bears would soon disappear because the Arctic would have ice-free summers by 2013 or 12014.  (This summer’s ice cover minimum was 4.9 million square kilometers  Current ice cover is 9.9 sq. km.)

Dr. Susan Crockford is a Canadian zoologist and professor who has been studying polar bears in the Canadian and Alaskan Arctic for more than three decades.  She says the actual data is a whole lot different than the article claims.  Yes, there was a drop in bear population between 2004 and 2006.  Estimated drop was 25-30% of the population.  The time corresponded to a series of years with thicker than normal sea ice in the spring.  (Yes, a colder time.)  Then spring sea ice diminished though about 2012 .  What happened to the bears?  Their population grew back to pre-2004 levels and is thought to be still growing.

Yes, that’s just the opposite of what the so-called greens have been shouting to us for almost a decade.  Just goes to show you what happens when non-scientists start preaching about science!  We could have saved a lot of time and effort if we’d just believed the real experts – the Inuits.  Old saying among the Arctic dwellers- Warming weather brings more polar bears!

Winter gets an early start

Thursday afternoon

After a two month hiatus, I’m back again.  Weather patterns have certainly taken on a winter look early, so perhaps the coldest part of winter may well be the first half with an easing during the later winter.  But, those thoughts are just speculation at thjs point.  The forecasters I think do the best seasonal forecasting  (the gang at Weather Bell Analytics) are predicting another very harsh winter for the eastern two-thirds of the U.S.  One the best analog years is 1976-77.  If you remember, January 1977 was by far the coldest month in Louisville’s history.  That’s not to say it’s going to happen again – just that the weather patterns of the past 6-9 months are a very close parallel to the same time in 1976. And, the winter of ’76-77 ended very early.  By the second week in February, we were into a major warming trend which brought us an early Spring

Meanwhile, the “official” National Weather Service’s winter forecast continues its seemingly decades-long trend of forecasting normal to above normal temperatures for most of the country (only Texas and parts of surrounding states) are predicted to be below normal).  The NWS has had a long running warm bias in their winter outlooks and this year seems to be another in that long string of misses.  Meanwhile, the November temperature outlook issued Oct. 31 has NO area of the U.S. predicted to have below normal temperatures.  Two weeks into that outlook, we know it’s an error of huge proportions.  And, it really puts a major CAUTION sign on the rest of their current suite of products.  Time will tell, but I think Weather Bell is far closer to the truth than our government’s outlook.

WEEKEND SNOW?

Things can certainly change over two days, but at this time it appears to be a case of “How much?” rather than “Will it snow?”  Yesterday the NAM and GFS models were far apart in their solutions as to how the weekend weather pattern will evolve.  Today, they’ve come closer together, but still with different leanings.  On the big picture, both forecast snow for Saturday night into Sunday morning.  Both models expect a weak, unorganized system and thus not much precipitation.  Current estimates place accumulations of up to one inch of snow – mostly on grassy areas.  The big question for the models is What happens next?  The NAM produces a second system Sunday night/early Monday that drops a second snow, but keeps it south and east of Louisville area (watch out eastern KY, could be some heavy snows, if this pans out.)  However, as it often does, the GFS slows things on Sunday and allows a stronger secondary storm system to form.  If this scenario develops, the Louisville area will become a prime target area with a swath of 2″-4″ of snow possible.  But, it’s far too early to know how things will evolve.  More tomorrow!

 

 

Cooler for the weekend

Friday afternoon

Weekend weather picture seems to be getting into better focus.  One thing is a sure bet- cooler temperatures.  Should be near 80 tomorrow and 78-80 on Sunday.  Much lower humidity slowly arrives tomorrow with its full effect felt by Sunday.  The question remains about rain.

I mentioned yesterday that any rain probably would not arrive until Saturday.  Now I’m starting to ask the question, “Will we get any rain at all?”  My answer is still “yes”, but it’s a pretty shaky yes.  Right now we’ve got a little of everything – warm, humid air mass, upper level energy approaching, and lower level convergence with a weak cool front.  Perfect set-up. But, the timing is all messed up!  First, the moisture is confined to the lower atmosphere – no help from the mid-levels (a negative).  Second, the strongest surge of upper air support should pass over the area around Midnight-3 A.M.  That’s several hours earlier than the cold front.  So, the energy arrives while the moisture is confined to low levels and the cold front is not around to support lifting air (another negative).  Third, when the cool front arrives (around 8 A.M.), the upper air support will be gone but the moisture will be higher in the mid-levels.  Without the upper support, the combination of a weak cool front and marginal moisture may squeeze out a few morning showers, but they will be light (probably .10″ or less).  Any appreciable rain should be gone by Noon or 1 P.M.

So, as you can see, there are a lot of things to consider for the next 24-hour forecast.  But, here’s what I’m thinking now…

Tonight:  partly cloudy and muggy…30% chance for a brief shower or thunderstorm after midnight.   Low… 74

Tomorrow:  Cloudy in the morning with a 30% chance for light showers, then mostly cloudy and cooler during the afternoon…high…80.  Clearing and cooler tomorrow night…low…60.

Sunday:  Mostly sunny and pleasant…high…78.

Forecasting note

Yesterday morning when I checked the forecast models, I was pretty convinced that today would be rain free around here, so I was pretty surprised the weather service went as high as 40% chance for this afternoon. During the afternoon, I did a quick check of some local media sites and they were generally leaning to the “low or no” rain chances scenario as well.  So, frankly, I was surprised when the weather service forecast continued with 40% storm chance for this afternoon.  This is one of the things I found really frustrating when I was working – when they latch onto a forecast, they seem to hold on far too long EVEN when everything they are looking at is telling a different story.    (Sorry about that, but I’m trying to work through years of frustration.)

Anyway. by their morning forecast today, they had dropped down to 20%.  Still too high as the rain train had left the station by that time,  but at least an acknowledgement they were catching on.

Another forecasting point about that forecast.  In general, since Tuesday, most forecasts had both yesterday and today with highs in the 90’s.  As it turns out, an accurate forecast.  But, yesterday with the weather service’s 40% chance for rain, the high predicted for today was dropped to the upper 80s.  That’s a good move – with a higher rain chance (which would cool the air) and most likely more clouds even if rain didn’t fall,  temperatures should be lower.  However, this morning when they pretty much dropped rain out of today’s forecast, they forecast a high in the upper 80’s.  Why?  (With rain and clouds gone, isn’t it reasonable that it should be a few degrees warmer?)

Brief showers

Thursday afternoon

A line of light showers moving through the afternoon won’t last very long.  We seem to find ourselves in the wrong spot at the wrong time situation.  A look at the satellite image belowvissatshows two lines of clouds with light showers being produced by a weak cold front pushing southward.  These showers will fade before sundown, but the cooler air will reinforce the pleasant, dry air mass we’ve been enjoying.  (By the way, good call by the National Weather Service to add in that chance for showers this afternoon.

If you look to the upper-center( Iowa, Minnesota and South Dakota) of the image you will see the classic satellite view of an upper level disturbance.  This one will drop slowly southeast and bring us increasing cloudiness by late tomorrow.  As the system crosses north of us on Saturday, we’ll see a lot of clouds (with a small chance for some light showers) early in the day, The primary effect this system will have on us will be to bring in much higher humidity.  Then, as skies clear Saturday afternoon, We’ll really know that summer’s definitely not finished.  Once the humidity  is in place all we have to do is wait.  A few more of those upper air disturbances are expected to follow the one on the satellite image above.  Some periods of showers/thunderstorms should become more likely, perhaps early Sunday, but a better chance late Sunday and Monday.

 

Changes coming from the Storm Prediction Center

For years we’ve been receiving “Severe Storm Outlooks” from the Storm Prediction Center with three familiar categories – Slight Risk, Moderate Risk and High Risk.  These Convective Outlooks, as they are officially known, appear as maps showing locations where the forecasters expected the possibility for thunderstorms that day and pinpoint areas where they believe severe storms are possible.  The slight, moderate and high risk delineate areas based on the expectations where the most widespread and intense severe storms will be located.

That system will end October 22.  The types of outlooks will grow to five with the addition of “marginal” and “enhanced”.  It is very hard for a forecaster to just draw a line separating expected non-severe and severe regions.  It’s my belief that most of the time, SPC forecasters use the “better safe than sorry” philosophy.  As a result, I believe that in general practice the daily “Slight Risk” category is considerably larger than it should be.  So, I’m happy to see the addition of the Marginal Risk category.  This should eliminate the problems with the lower end of the storm spectrum and ease the worry many people have when they hear “Slight Risk” in the morning.

The “Enhanced Risk”  category covers the border between Slight and Moderate, also a   confusing boundary.  The jump from slight to moderate currently means higher areal coverage AND more numerous and intense storms (over a 10,000 square mile area, say).  Nature doesn’t always cooperate, however, especially when you have two specific criteria to satisfy.  For instance, suppose the area to be hit exceeds the “slight” criteria, but the storms aren’t expected to exceed low-level severe?  Or, vice-versa?   Enter “Enhanced Risk” for that “fuzzy”  zone.  Here’s an example of what it will look like.spcoutlooks

 

 

Heat and humidity return for the weekend.

Friday afternoon

August is off to a warm start, but at least the humidity is still low.  That all changes for the weekend as both the temperatures and the humidity will be on the rise.  And the models continue their slow decline in rain chances.  So, it looks like a pretty typical late summer weekend…hazy, very warm and humid.  Rain/thunderstorm chances are not zero, but pretty close.  Best chance still looks like tonight, but only at 20% or less.  Saturday and Sunday rain chances will max out under 10%.  Temperatures tonight should drop to around 70 and about 72 Sunday morning.  High temperatures should reach the upper 80’s.  Similar weather should continue early next week.

More climate talk

Yesterday, I closed with a statement about the headlines concerning a return to “an ice age is coming” within the next ten years.  That was not said in jest to mock the climate claims of the past century.  Rather, it’s based on observations of past reactions of weather to ocean currents.  Yes, ocean driven weather cycles.  The two major patterns are the Pacific Decadal Oscillation (PDO) and the Atlantic Multidecadal Oscillation (AMO).  Both the PDO and the AMO have two phases – positive(warm) and negative(cold).    The PDO was generally in a positive mode from the mid 70’s (when recent global warming began) until it flipped to the cold negative mode around the year 2000.  The Earth hasn’t warmed since.  (What a coincidence!) Meanwhile, the AMO has been generally positive much of the past 25-30 years.  A few years back it started “flipping” but hasn’t settled into the cold mode yet.  It’s expected to definitely become a cold phase over the next year or two.  Historically, when both the PDO and the AMO are in their cold phase, the Earth cools.  (Coincidence?  our warm Earth climate leaders think so.)

Another possible contributer to cooling could be sunspots.  The sun, of course, is the reason why we a here.  But, for centuries we looked for the “solar constant” the exact amount of energy the sun sends our way each day.  For some reason, the scientific community thought this number had to be a constant.  It’s extremely difficult to measure the sun’s energy through the atmosphere, so the answer was never found…until satellites arrived.  Then, we could easily measure that solar constant.  But, it turns out there is no solar constant – the sun’s output varies on a cycle that closely matches the number of sunspots.  Currently we are at the end of a “solar max” that has been the weakest since around 1900.  Low sunspot numbers then were associated with a “cooling Earth”.  Even lower minimums have occurred.  The most well known is the Maunder Minimum – a period of over 100 years of very low sunspot numbers centered over the 1700’s – right in the middle of the period known as the Little Ice Age.  (Another coincidence?  you betcha! says the warm Earth society.)

ALL the CLIMATE MODELS our country’s so-called experts use project temperatures on a straight line upward from 2000 until 2020.  Well, we’re 70% of the way there and temperatures haven’t budged.  Let’s see how things stand in 6 years – I’m betting on colder.

Cool weather is over for awhile

Thursday afternoon

No problems with our weather recently and perhaps just a few bumps in the road over the next few days.  The basic features have remained the same.  Weak upper air disturbances will drift over the region late tomorrow through Sunday, but the main moisture source will stay far south and east of our area.  So, the already weak upper systems shouldn’t be able to produce some light and scattered showers.  At the moment, the most likely time for any showers looks to be Friday night.   Skies should be partly cloudy with highs in the upper 80’s and lows creeping up to the 70-72 range.  Highest rain probability will be 30% for Friday night.

Climate controversy continues

Hard on the heels of my comments yesterday concerning Earth’s warming during the 20th century.  Turns out that the warming (probably aided somewhat by carbon dioxide) was highly beneficial to mankind.  Our government scientists won’t tell us that because it ruins the story they’ve been trying to sell us – that carbon dioxide is evil and will destroy us. Fact is carbon dioxide has been crucial to the development and maintenance of life on Earth.  Without it, we wouldn’t be here.

Well, today’s report  on www.wattsupwiththat.com   shows that the “climate crisis” is a variable thing…and it runs on roughly a 40-year cycle.  A warming Earth was the big concern for about the first 40 years of the century.  Cooling began in the 1940’s and the “an ice age is coming” crowd got very loud in the early 1970 ‘s.   Then, warming resumed  and by the late 1980’s the cry “we’re killing ourselves with carbon dioxide” started to become very loud.  And it’s still going strong… in spite of the fact that Earth has not warmed  this century.  By my reasoning, we should be back to the ice age warnings within the next ten years!.

And like most people we’d like to see the world a better place, which in this context translates into our working to reduce the risk of potentially disastrous climate change. To do that we need to get some broad based support, to capture the public’s imagination. That, of course, means getting loads of media coverage. So we have to offer up scary scenarios, make simplified, dramatic statements, and make little mention of any doubts we might have. This “double ethical bind” we frequently find ourselves in cannot be solved by any formula. Each of us has to decide what the right balance is between being effective and being honest.

The actual Global Warming Advocates’ chart, overlaid on the “climate change” hysterics of the past 120 years. Not only is it clear that they take any change and claim it’s going to go on forever and kill everyone, but notice that they even sometimes get the short-term trend wrong…

climate-claims

Worse still, notice that in 1933 they claim global warming has been going on for 25 years…the entire 25 years they were saying we were entering an ice age. And in 1974, they say there has been global cooling for 40 years…the entire time of which they’d been claiming the earth was getting hotter! Of course NOW they are talking about the earth “warming for the past century”, again ignoring that they spent much of that century claiming we were entering an ice age.

The fact is that the mean temperature of the planet is, and should be, always wavering up or down, a bit, because this is a natural world, not a climate-controlled office.

 

Returning to normal.

Wednesday Afternoon

The run of pleasant weather is beginning its fade.  Another cool night then back to the mid 80’s (at least the humidity remains low ).  By Friday, a  bit warmer and more humid.  The NAM and GFS continue to bring some very weak upper air systems into the area by late Friday into Sunday.  Both models continue to keep any significant moisture south and east.  There could be some substantial rains along the Appalachians this weekend, but it looks like the systems will be unable to get much water this far north. So beginning late Friday, we will continue with small chances for a small amount of rain.

GFS projects the near normal weather pattern to continue for at least the first half of next week.

I couldn’t believe my eyes!  Right there in the CJ before my very own eyes was a story released by the Government stating that cold weather kills far Americans than hot weather annually.  Of course, this is not news.  However the current “climate crisis” crew that seems to control our national government’s science just doesn’t (ordinarily) let that kind of information be released to the public.  Cold is worse than warm concerning mortality.  Fifty years ago the statistics were roughly 2 to 1.  Now, it runs closer to 1.5 to one.  Does that mean that cold air deaths are actually falling.  In this case the answer is yes.  Does that mean that Earth’s warming has actually been good for us?  Yes.  The things that have improved are almost uncountable.  Probably the most important has been the amazing increase in food production (not solely because of warming)  that feeds several billion more people than when the 20th century began.  Interestingly, 40-50 years ago some highly respected scientists were forecasting that by the end of the 20th century, the Earth would be in constant famine and on its way to destruction by constant food wars!  Sounds very similar to what a lot of famous “scientists” are proclaiming about a warming Earth. So, far the warming has been very beneficial, but there’s been no warming for the past 15 years!

Long run of pleasant weather lies ahead

Midday Sunday

What a night!  The first midwestern system did arrive a little early with some strong winds, some scattered minor damage, lots of lightning and a very much needed significant rainfall.   Then, the second system arrived right on schedule around 5 A.M with a repeat of the first system.  Storms are now moving rapidly away and skies should slowly clear this afternoon.  Seasonably cool, dry weather should be the weather pattern through much of the upcoming week.

Note: a Tornado Watch covers much of Kentucky south and east of Louisville.  However, as of 1:15 this afternoon, the line of potentially damaging thunderstorms has moved southeast of a line from Lexington to Bowling Green.  So, no one within a 50-mile radius of Louisville is in any danger from thunderstorms this afternoon.

Just what is a severe Thunderstorm?

The National Weather Service defines a severe thunderstorm as having large hail, at least 3/4 inches (0.75 inches) in diameter, and/or damaging winds, at least 58 mph, or 50 knots

58 mph winds are really strong.  They do lots of damage.  They are pretty rare around here.  Last night’s two rounds of thunderstorms generated  plenty of warnings but not a whole lot of damage.   (There’s an old story to answer the question posed by this article -“If the whole neighborhood has several large limbs and trees down,  but my property is untouched, it was a strong storm.  However if my neighborhood has no damage, but I’ve got a big limb down, it was a severe storm.”)

There’s an old saying in the weather business that states a few trees down DOES NOT a severe thunderstorm make!   Very true.  Thunderstorm (and non-thunderstorm) winds can do  tree (and other) damage with wind speeds as low as 30-35 mph.  As the winds increase so does the ability to do damage.  For instance, a wind gust of 60 mph has 44% MORE FORCE to work with compared to a 50 mph gust.

I looked at last night’s data from area airports.  The HIGHEST wind gusts recorded were at Ft. Knox – 32 mph.  Lexington, both Louisville airports, Bowling Green, Huntingburg (IN), and Frankfort had top wind gusts in the 20’s.  Louisville’s Standiford Field’s top gust was 23 mph (at 5 P.M., when the skies were sunny).

I also checked the Kentucky Mesonet.  The highest gust around the state was in Bullitt County with a gust to 53.4 mph.  Hardin, Shelby and Taylor Counties all measured around 49 mph while just about everyone else was in the 30’s or lower.  Now one wind, measured at a single site, does not mean it has to be the highest in that county.  Thunderstorm wind gusts can vary quite a bit over short distances.  Case in point being Franklin County.  The airport’s top gusts overnight were in the mid 20’s (they’ve  had a higher gust this morning) while the mesonet station reached 41.3 mph.

But, when you look at several dozen reports and the large majority only saw max gusts in the 20’s and 30’s, you have to believe that the outliers  in Bullitt, Shelby and Oldham Cos. were probably pretty close to the top of nature’s production overnight.  It’s quite likely parts of Bullitt County reached the magic 58 mph target.  Possibly parts of Shelby and Oldham also reached it.

So,  by the actual “ground truth” of the raw data, our region did not have any severe thunderstorms last night.  But, based on interpretation of the data distribution, it’s likely a few spots(but only a few)  did reach the 58 mph hour criteria.  There were plenty of Warnings issued, there was some damage, but did we have any “severe” storms  based on the official definition?  Well, as the little story at the beginning of the essay illustrates, It’s all in YOUR perception!

Hot start to the week

Monday afternoon

It’s hot, but at least the humidity isn’t too bad.  Current dew point is 65, right on the bottom end of when humidity starts adding discomfort.  General rule is that dew points below 65 cause little problem for the majority of the population.  However, when the dew point rises above 65, the humidity really gets noticeable.  For this area, Dew points at 70 or above can make the air feel oppressive.  The dew point, by the way, is the temperature to which the air must drop for the air to be 100% saturated.  So, dew points are an absolute way to express moisture in the air.  The higher the dew point, the more moisture is in the air.  Relative humidity, a more familiar term, is highly variable and values change widely during most days.  I know you’re not supposed to define a word by using, but relative humidity really is “relative” (to the air temperature).  More on this at a later date, if anyone is interested – or even if you aren’t!

Back to the weather…there’s a large, weak upper air disturbance over the deep south that is bringing scattered showers/t-storms from the Gulf Coast as far north as Tennessee and east as far as the Carolinas.  This system has been cut-off from the normal wind patterns over the northern U.S.  As a result it is just drifting aimlessly.  Forecast models continue a general weakening trend with a WSW direction.   Thus, higher moisture will be trapped by this system and discourage northward movement.

That becomes the big question mark for our midweek chance for rain.  As usual, the NAM family and the GFS have their differences.  But, once again, none of the models is expecting much rain.  The NAMs are faster and stronger but bring in rain/t-storms during  the morning – the worst time for significant rain.  Meanwhile, the GFS holds off the rain/t-storms until about 4-10PM.  That allows time for more heating, but thunderstorms also need moisture.  That’s being trapped by the southern system.  Neither system holds out much hope for a decent amount (say, .50″ or more) of rain.

As I’ve mentioned before, beyond a day or two the GFS seems to be better.  So it looks like tomorrow and Wednesday should both reach the lower 90’s with a good chance of late day thunderstorms on Wednesday.

Commentary (and a bit of bragging)

As I write this, my wife and 12-year old granddaughter (Holly) are downstairs in the sewing room.  My wife sews a lot (quilt-maker) and Holly has always been fascinated and has been learning for years.  Today they are working on a charitable project called Dresses for Africa.  The original idea used pillow cases to make a quick and easy dress for young girls in Africa.  They made five a few weeks ago and are back at it again.  Here’s a picture of Holly’s first efforts.       016  If you sew or know people might be interested, you can get all the information at www.littledressesforafrica.org.
