UPDATE FOR AVIATION...

.PREV DISCUSSION... /Issued 339 AM EDT Tue Sep 17 2019/

SHORT TERM /Today through Wednesday/...
Another Hot day in store with high temperatures running in the
mid 90s to near 100 for most locations except the mountains.
These temperatures could set/tie a couple of records across the
area and most likely at ATL and MCN.

A weak cold front is expected to drift south across the area
today and into Wednesday then a ridge of high pressure will
build down the Appalachians Wednesday, bringing cooler temperatures
to the area.

Rain chances are limited to the far northeast and east today into
tonight as overall moisture is limited.

As the surface high builds on Wednesday, some added moisture and clouds
can be expected along with a 20 to 30 percent chance for a shower or
thunderstorm.

Forecast high temperatures are running about 9 to 15 degrees above
normal across much of the area today and around 1 to 10 degrees above
normal on Wednesday as cooler air moves in. Forecast low temperatures
are running about 7 to 12 degrees above normal for tonight.

Overall confidence is medium to high.

 SHRA/TSRA in the NW corner of GA on
Monday, the long term period will be completely devoid of precip
chances.

00Z model guidance shows upper ridge still dominant feature Thursday
through Monday even while we enjoy a relatively brief period of
cooler/drier weather Thurs-Saturday thanks to surface wedge of high
pressure. Sadly, upper ridge progged to build back in starting
Sunday. 00Z guidance also a little slower than previous runs to
bring westerlies down into north GA so backed off PoPs on days 7
and 8.
