Short term /today through Saturday/...
short term models are in pretty good agreement. Northwest flow
aloft with a wave will move across the area through the period. At
the surface...a weak boundary will shift to the south through
tonight...allowing high pressure to build in from the northeast
tomorrow. This will bring north to northeast flow to the area.
Models showing good moisture across the area and with day time
heating expect isolated showers and thunderstorms this afternoon.
Better rain chances on Saturday as wedge front pushes westward.
Instability will be minimal with just isolated thunder expected.
Guidance temperatures are close today and tonight and see no
reason to stray. High temperatures on Saturday will be dependent
upon the amount of cloud cover with The Wedge...with a larger
spread in guidance temperatures over East Georgia. Have gone with a
blend most areas and stayed closer to cooler mav over eastern
areas.

Long term /Saturday night through Thursday/...
upper low will be situated across the southeast states at the
beginning of the long term portion of the forecast. The low will
continue through the remainder of the weekend...but should open up
and become an open wave across the northern Gomex by early next
week. The middle level flow may try and go more zonal across the County warning forecast area
during this time.

At the surface...wedge of high pressure across the area Sunday into
Monday should eventually erode by the middle of the week. A cold
front will begin to drop south across the County warning forecast area during the latter
half of the week.

VFR ceilings will continue through the period. Winds will be light
west to northwest with north-northeast winds after 14z. Continue to think
isolated thunderstorms and rain possible this afternoon but expected coverage too low
to mention in tafs.

medium to high confidence all elements.
