.SHORT TERM /Tonight through Friday Night/...

Water vapor showing some drier air spreading into north and central
GA this afternoon. At best...looking for only isolated convection
with better chances south of Columbus to Macon. Have removed all
pops after 06z. However...a surface boundary is forecast to push
into north GA around 12z and the possibility remains for some
development along and ahead of this feature overnight mainly north.
For now...will watch and see. This surface boundary...associated
with the short wave dropping into the mid Atlantic states...should
push into central GA by Friday afternoon. Expect best pops for
Friday mainly central GA ahead of this feature but still only in the
chance category. Drying continues Friday night into the central
zones. Mav/Met blend of temperatures looks okay.

.LONG TERM /Saturday through Thursday/...

Extended forecast looks to be on track, and have made minimal
adjustments. Have tried to accommodate the timing differences between
the extended models for the mid-week fropa next week (Day 7 and 8)
by taking a blend of the solutions. Both models seem to have trouble
resolving the front and dry air behind it before a secondary upper
level disturbance moves into the region. For now have gone with
slight chance to chance pops for Wednesday and Thursday.

Milder temperatures (highs in the 80s, lows in the 60s) through the
weekend will warm up once again by Tuesday with highs back in the
90s across the state.

Previous forecast discussion is included below.

LONG TERM /Friday Night through Wednesday/...
The extended forecast starts off with the upper level longwave
trough just off the eastern seaboard and its associated wave just
off the Carolina coast. This trough pushing off the east coast
will allow a drier airmass to slowly push into N GA Sat
morning...with an over all drying trend setting up for the
remainder of the extended forecast. It is good to see much better
agreement between the ECMWF and the GFS this morning in the
extended portions of the forecast. Both models show the surface to
upper level ridge over the New England states building southward
into GA Sat morning...and continuing to dominate the weather
pattern through the middle of next week. Both models are also
showing a weak cold front moving south out of the great lake
states Tue morning and pushing into N GA by Wed morning. This
front will bring rain chances back to the area for day 7 but only
putting in a slight chance for now. The drier airmass that moves
into the region Sat will also usher in some cooler temps to start
the extended forecast. looking at high temps Sat through Monday
mainly in the 80s. Temps will rebound back into the 90s by Tue/Wed
of next week.

.AVIATION...
18Z Update...
Some drier air working its way into the forecast area. Expecting
vfr through the period...with few or sct040-050 this afternoon.
Chance of convection too low to mention...but any development should
be mainly KCSG to KMCN and south. Winds will remain on the west
side...and frequent gusts to around 20kt are possible this afternoon.

//ATL Confidence...18Z Update...
High confidence all elements.
