SHORT TERM /Today through Friday/...
Latest regional surface analysis indicates wedge front has made
it just about out of the area with the majority now over portions
of eastern Alabama. Behind this feature, high pressure continues
to wedge in through the Carolinas and the local area. Dewpoints
already significantly lower with mid to upper 50s across most
locations and this has resulted in lower min temps as well.
Despite an abundance of cloud cover, sites like Atlanta which
were around 80 degrees this time last night, are some 8 degrees
lower tonight.

Expect cloud cover to remain over the area for most of today and
gone on the higher side of guidance for cloud cover. Still think
there could be enough sun late though to allow for temps to just
creep into the lower 80s for North GA. But should the clouds hang
on just a little longer though, would not be surprised to see
some upper 70s high more in line with the MAV guidance.

First cool down as we approach the fall season in store for
tonight with lower 50s for the mountains and mid to upper 50s
elsewhere. Should be clearing skies and lower winds which should
enhance radiational cooling conditions. One additional day around
climo in store for Friday with lower 80s for most locales although
mid 80s will be the rule over Central GA.

LONG TERM /Friday Night through Wednesday/...
No major concerns for the long term period with mostly
dry weather expected. High pressure is expected to predominate
through the weekend.

A weak cold front is forecast to move into the area late Monday
to early Tuesday and become stationary late Tuesday into
Wednesday. This is where the GFS and European differ with the
European mainly dry and the GFS having more and moisture and
producing some rain amounts from late Monday into Wednesday over
portions of the forecast area.

Will keep things dry for now until there is more consistency
between the models with rain chances.

Temperatures are expected to be within several degrees of normal
to start but warm to above normal from Sunday/Monday and beyond.
