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!.

  • 1981 – Global Warming – “of an almost unprecedented magnitude” – New York Times
  • 1988 – I would like to draw three main conclusions. Number one, the earth is warmer in 1988 than at any time in the history of instrumental measurements. Number two, the global warming is now large enough that we can ascribe with a high degree of confidence a cause and effect relationship to the greenhouse effect. And number three, our computer climate simulations indicate that thegreenhouse effect is already large enough to begin to effect the probability of extreme events such as summer heat waves. – Jim Hansen, June 1988 testimony before Congress, see His later quote and His superior’s objection for context
  • 1989 -“On the one hand, as scientists we are ethically bound to the scientific method, in effect promising to tell the truth, the whole truth, and nothing but – which means that we must include all doubts, the caveats, the ifs, ands and buts. On the other hand, we are not just scientists but human beings as well. 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. I hope that means being both.” – Stephen Schneider, lead author of the Intergovernmental Panel on Climate Change, Discover magazine, October 1989

  • 2006 – “I believe it is appropriate to have an over-representation of factual presentations on how dangerous it is, as a predicate for opening up the audience to listen to what the solutions are, and how hopeful it is that we are going to solve this crisis.” — Al Gore, Grist magazine, May 2006
  • 2006 – “It is not a debate over whether the earth has been warming over the past century. The earth is always warming or cooling, at least a few tenths of a degree…” — Richard S. Lindzen, the Alfred P. Sloan professor of meteorology at MIT
  • 2006 – “What we have fundamentally forgotten is simple primary school science. Climate always changes. It is always…warming or cooling, it’s never stable. And if it were stable, it would actually be interesting scientifically because it would be the first time for four and a half billion years.” —Philip Stott, emeritus professor of bio-geography at the University of London
  • 2006 – “Since 1895, the media has alternated between global cooling and warming scares during four separate and sometimes overlapping time periods. From 1895 until the 1930’s the media peddled a coming ice age. From the late 1920’s until the 1960’s they warned of global warming. From the 1950’s until the 1970’s they warned us again of a coming ice age. This makes modern global warming the fourth estate’s fourth attempt to promote opposing climate change fears during the last 100 years.” – Senator James Inhofe, Monday, September 25, 2006
  • 2007– “I gave a talk recently (on fallacies of global warming) and three members of the Canadian government, the environmental cabinet, came up afterwards and said, ‘We agree with you, but it’s not worth our jobs to say anything.’ So what’s being created is a huge industry with billions of dollars of government money and people’s jobs dependent on it.” – Dr. Tim Ball, Coast-to-Coast, Feb 6, 2007
  • 2008 – “Hansen was never muzzled even though he violated NASA’s official agency position on climate forecasting (i.e., we did not know enough to forecast climate change or mankind’s effect on it). Hansen thus embarrassed NASA by coming out with his claims of global warming in 1988 in his testimony before Congress” – Dr. John S. Theon, retired Chief of the Climate Processes Research Program at NASA, see above for Hansen quotes

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.

Climate/Commentary

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!

Another break from heat and humidity

Tuesday midday

Very pleasant (and unusual) July weather continues and should last, although with slowly warming day by day through Thursday.  When we get these below normal temperatures they are brought in by upper level troughs (basically a huge pocket of colder than normal air aloft.  This destabilizes the atmosphere so that daytime heating tends to generate a large amount of afternoon cloudiness.  You saw it yesterday and we’ll see it again today and tomorrow.  Sometimes there is enough moisture to produce a small amount of precipitation.  An example is snow flurries after the arrival of a blast of cold air.  When it happens in the summer, once in awhile it generates some small, light showers.  Today’s models bring in a little more moisture than yesterday, So, is possible we could see a few brief showers this afternoon and evening, especially over southern Indiana.

Starting Friday, the chance for rain will return.  GFS and NAM are pretty weak with this next system.  It will definitely be moisture-shy as upper level winds will stay from the northwest.  So, it’s a good thing we got some pretty good rains last weekend.

Space news

The summer’s best time for viewing meteor showers comes in August with the Perseid Shower.  This year’s peak is expected to be August 11-13.  However, it won’t be nearly as “viewable” as most years.  The peak coincides with the largest, brightest full moon of the year.  So, the usual predictions of “up to 120 per hour”  have been lowered to about 30 per hour.

Astronomers have been watching the skies for possible asteroids that could be on collision paths with Earth.  As of today, we know of 1493 Potentially Hazardous Asteroids. These PHAs, as they are commonly known are defined as asteroids which are greater than 100 meters in diameter and have orbits that bring them within 5 million miles of Earth.  An impact would be devastating to our Earth, but at this time none is known to have an orbit that would create a direct impact here.  That’s the good news, the bad news is that PHAs are still being discovered.

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!

Another update

Saturday afternoon

Recently, radar indicates the third system I mentioned earlier has organized faster than thought.  So, the time line I just issued should probably be shifted forward a few hours.  Showers/tstorms could reach the Louisville area as early as 10 P.M.  If so, that will increase chances for severe storms locally.

4 PM update

Saturday Afternoon

The model trends mentioned this morning are starting to fall into place.  A strong cluster of thunderstorms has formed over northern IN and parts of western OH.  This is expected to consolidate into a large system and spread SE over OH into far NE KY and West Virginia.

Next system is starting to appear over northern IL.  It is also expected to strengthen and spread SE – mostly likely staying north of southern IN and the Louisville.  This system should be spreading north of us this evening – 8 to Midnight.

The piece of atmospheric energy we are concerned about for us is a disorganized area of scattered thunderstorms over southern MN, WI, Iowa and western IL.  This system looks to be the biggest of the three and should travel SE farther south than the first two.  It looks likely we’ll plenty of Severe Storms over IL and Western IN this evening until Midnight or later.  What’s left of the system should then begin fading as it moves toward the Louisville area.  Some thunderstorms could arrive here as early as Midnight, but it appears as though the best chances will be around 2 A.M. and, even more likely between 5 and 9 A.M.  All rain is expected to end  by late morning

The severe storm threat still looks very low within 35 miles (or so) of Louisville.  But, if anything “severe” is going to happen. 5-8 A.M. would be the most likely time.

Rain/storm chances dropping (quickly)

Saturday Morning

A quick look at the morning model runs continues the trends noted yesterday.  The HIRES NAM model doesn’t even produce ANY rain for the Louisville area – keeping the heavy rain/storm threat from northern IN to SW Ohio, eastern KY (east of I-75) and West Virginia.

The NAM continues yesterday’s trend, but in a much weaker fashion.  It now pushes a line of showers/t-storms through the region after midnight with the majority of rain (on the light side) ending before Noon.

The GFS as usual is the slowest.  It is also a weakened version of yesterday.  It holds off the rain/storm cluster until well after Midnight with all rain wrapping up shortly after Noon. Again the rain totals predicted are much lower than yesterday’s prediction.

So, here’s my latest forecast:

Afternoon:  partly cloudy, hot and humid…high 90ish (a highly technical term

Tonight:  20% chance for thunderstorms until midnight.  After Midnight, showers and thunderstorms are likely.  Gusty winds possible.  Rain chance 60%.  Low…72.

Tomorrow:  Showers end during the morning, then sunny and breezy in the afternoon…high…87.

Severe Storm Threat

Most, if not all, of the severe weather will occur over eastern Indiana and SW Ohio (and southeast from there).  An isolated severe thunderstorm is possible,  but not likely, within 35 miles of Louisville.

There is also talk of a second chance for severe storms tomorrow afternoon or evening.  To me, this seems like someone’s idea of a bad joke.

Big Change in August outlook

Friday afternoon

I’m not much of a fan of extended outlooks and/or long range forecasting.  Nevertheless, I do check a model that portends to go out weeks and months.  That model is known as CFSv2.  I like to see the slow, usually subtle, forecast changes the model picks up.  But today I noticed a big shock – a dramatic one week change in August’s outlook.

Below is the forecast from July 17.  The top left image is the raw computer output.  The upper right is a statistically “normalized” version of the raw data.  The bottom images are probabilities of occurrence.  Notice the eastern U.S.  Forecast for an above normal surface temperature (2 meters) is quite evident.

CFSv2Aug

That was July 17.  Here’s the same image from today’s run…

CFSv2AugNEW

An amazing flip-flop!  If correct, we’re looking at a very nice August.  But, if it flips once, it can flip again.  This is a perfect example why I don’t like forecasting beyond 3 days.

Scoping out the weekend weather

Friday Morning

It’s like a three ring circus today – three models, three different solutions.  Trying to put it all together, here are a few things I’m pretty confident about.  1).  Our weather should remain dry through 6 P.M. Saturday (except for a small possibility for a few sprinkles overnight).  2).  Severe thunderstorms appear likely tomorrow night over northern/central Indiana moving into Ohio by Sunday morning.  Severe chance for Louisville area looks to be very small as peak storm chance for us will come from about Midnight Saturday until 8 A.M.  Sunday.  3).  One thing the models do agree upon is expected rainfall from this system.  Yesterday they placed a 1″+ swath of rain over most of IN and KY.  Today’s forecasts have dropped that by more than half.  Now the models are putting a 1-2″ path generally from Indy to Cincinnati with rapid dropoff south of that line.

So this could be a very interesting, and frustrating weekend for us forecasters as many things could go wrong.  But, forecast the weather is what I do, so here’s what I’m thinking now:

This Afternoon:  Mostly sunny…high mid 80’s (low humidity)

Tonight:  Mostly cloudy and warm…a few sprinkles possible…low…72.

Saturday:  Partly cloudy, hot and humid…high…90

Sat Night:  Showers and thunderstorms likely, especially after midnight.  Strong gusty   winds possible..low’…70

Sunday: Showers/thundershowers ending by late morning, then partly cloudy and warm…high…86.

Pleasant again

Thursday Afternoon

Yesterday’s showers danced around the area with little to show for their efforts.  One exception was a narrow area of .25″+ rain from near LaGrange eastward into western Henry County. I have my sprinkler running right now.

Meanwhile pleasant weather will continue through tomorrow although it’ll be a little warmer in the afternoon.  The weekend should get off to a pretty good start – partly cloudy, upper 80’s and more humid on Saturday.  Then, we’ll begin to feel the effects of yet another upper air trough digging south into the Great Lake and Ohio Valley regions.  We’ve seen a lot of these systems this summer and have enjoyed the cool weather they’ve brought.  But, although they look very promising for rain several days in advance, lately they have failed to deliver on that promise.  Currently, the models are painting a large stripe of 1″ plus rains over the area.  But, even now, the models are putting some “red flags” on the rain outlook.  They are locking in on Midnight Saturday night until Noon Sunday as the preferred time for the most energy to be near us.  This time of year, that’s often a death trap for rain.  But, I’m sure there will be some changes to that outlook before Saturday.

Stuff – neat photo

Found the photo below from  www.spaceweather.com  Photographer was Stine Bretteberg and photo was taken in northern Norway.

sundog_strip

We are accustomed to the sun rising in the east and setting in the west.  But it’s not that way over all the earth.  Over polar areas of the Northern Hemisphere the sun never sets on the date of the Summer Solstice (usually June 20 or 21) and for several weeks either side of that date.  It’s commonly known as the Land of the Midnight Sun.   So, if the sun doesn’t set, what does it do?  It goes around and around in circles.  It starts in May as the sun hugging the horizon.  Each day until the solstice, the sun gets higher in the sky as it circles around the horizon.  After the solstice, it slowly winds back down.

The photo was taken around midnight with the sun sitting on the horizon while a layer of ice crystal clouds (cirrostratus, for Latin lovers) is in the sky.  As a result, several optical features all appear together.  First, the midnight sun; second, A large halo around the sun; and third, a set of sun dogs (parhelia) sitting in the halo at the horizon.  The Sun Dogs are the bright spots (often they have the colors of a rainbow faintly displayed) seen near the horizon directly east and west of the sun.

Addendum (also for my Latin speaking friends)

Talking about the sun’s behavior at high latitudes brings to mind an old story from a college textbook.  It seems an agricultural group , upon hearing about the sun’s polar activity, decided that would be the ideal place to raise sunflowers.  So they packed up some gear and headed off to the Land of the Midnight Sun and set of a greenhouse and planted their sunflower seeds.  At first, everything went well – the plants grew quickly and were tall and  e healthy.  Then, when the flowers started to grow, they did what sunflowers do – they followed the sun around and around and around until they slowly strangled themselves to death!
