Barry “underperforms”

Barry provides a wet night

Remember all the frightful forecasts about the flooding rains Barry would cause last weekend over Louisiana and surrounding states?  Well, the storm did produce the normal heavy rains that a tropical storm does, but the big weather story for the past couple of days has been Barry’s “underperformance.”  A huge part of the damage and destruction predicted never happened.  That’s the good news.  Here’s the bad news:  All the familiar meteorologists’s phrases popped up – “We dodged the bullet”, “We got lucky”, and “The storm underperformed”.  Ah!  The world we live in.  All the reasons given imply that the forecast was correct.  Thus, it was nature that blew it!

Note to fellow forecasters:  Nature does NOT make mistakes, but we do.  Isn’t it about time that forecasters actually own up to their mistakes and just admit them rather than trying to push the blame to “the weather”?

Barry’s moisture finally reaches us.

Barry’s remnants are being picked up by a weak upper air system over the midwest that will push eastward tonight and cross the lower Ohio Valley by midday tomorrow.  Ahead of this system we’ll see periods of rain and a few thunderstorms tonight.  There could be a few lingering light showers tomorrow, but the bulk of the rain will be overnight.  Current model trends are for the heaviest rains to occur over the western third of KY and over the eastern third of KY later tonight and tomorrow.  Both of those areas could see 1″-2″ rain totals with perhaps higher totals in the mountains.  Most of southern IN and central KY should receive up to an inch of rain with a few areas higher if thunderstorms develop.

Break in the heat coming?

For at least a month, the GFS model has been predicting a change in the upper air pattern over North America.  The forecast has always been for the shift/change to occur 10 days to two weeks ahead.  But “next week’s cooling” has never shown up…yet.

Late last week the forecast was for a transition to the cooler pattern to happen Sun/Mon (July 21-2).  Now we’re less than a week away and the forecast hasn’t changed.  Could it be “real” this time?  It sure looks like it.  So, a more comfortable weather pattern should set if next week.

Then, the question becomes whether the cooler pattern will persist for several weeks or just be  a minor “blip” in the summer heat.  Longer range models keep the cooler pattern in place for most of August.  We’ll just have to wait and see.

Stuff:

There’s been a lot of news and celebration this week concerning the 50th anniversary of the Apollo II moon landing.  Here’s a tidbit I read this week…

The Apollo II computer system required about 145,000 lines of code.   (Today, Facebook runs about 62 million code lines while Google uses more than 2 billion lines!)
