NEAR TERM [Today]...
A cold front across northern Alabama and north Georgia early this
morning will continue to drop south and into the Florida Panhandle
by this afternoon. Although convection out ahead of the front is
currently diminishing, we expect storms to increase in coverage
later this morning and afternoon with daytime heating.
A much drier airmass will be filtering into the region on northerly flow in the wake of the front. PoPs will be tapered from nil extreme
northern zones to mid range chance (40%) for our southern tier
Georgia and Florida zones. Max temps today will be in the lower to
mid 90s inland and upper 80s along the coast.
SHORT TERM [Tonight Through Sunday]...
The large scale longwave pattern remains amplified highlighted by
ridging over Cntrl Conus with high centered over LA/AR border, and a
trough along Ern most states into Wrn Atlc with axis just off Ern
Locally, this translates to dry NW/N steering flow.
At surface, low off mid-Atlc with weakening front Swd then Wwd along N FL/AL coast. During the rest of the overnight period, dissipating
front will move into Gulf of Mex then beyond our coastal waters by
In its wake...high over great lakes builds swd into Nrn Gulf region. Depending on actual position of front and residual moisture from rain, patchy to areas of fog expected mainly SE Big Bend.
During the rest of the weekend, the center of high will move into
LWR MS Valley on Sat then to the NRN Gulf overnight pushing the Ern
trough further into Atlc with a more zonal flow developing across
most of Ern Conus except for weak troughing over SE region with
Gulf high shunted farther in Gulf of Mex thru Sun.
At surface, high moves ewd exiting into Atlc Sat night with axis swwd and back towards N FL/S GA. Local flow veers to east then offshore by that time. So expect deep layer ridging leading to a drier airmass with wdly sct late aftn into eve precip with the focus south of ridge axis, namely south of I-10.
Also this will lead to lower humidities and heat indices.
Expect lows each night in the mid 60s to low 70s. Under NLY steering flow and lack of clouds, expect inland highs in the mid 90s on Sat and low to mid 90s on Sun.
LONG TERM [Sunday Night through Thursday]...
The upper pattern is forecast to remain relatively flat and weak
through the first half of next week. With a relatively dry airmass
in place, this will keep rain chances on the low end of scattered,
By Wednesday and Thursday, a trough is forecast to amplify along the eastern seaboard, which may improve rain chances.
Temperatures should remain near seasonal normals.
AVIATION...[Through 12z Saturday]
A diminishing line of convection ahead of a cold front will continue
to move to the south this morning. The storms should impact ABY and
DHN between 06z and 09z possibly resulting in MVFR to IFR
conditions. The remaining TAF sites could see convection before
sunrise but the best chance will come later this morning and
afternoon as additional storms develop along and ahead of the front.
The cold front should be south of DHN and ABY by 12z with VFR
conditions for the remainder of the TAF cycle.
Winds near exercise caution levels are possible overnight into early
morning ahead of an approaching cold front.
The front will stall very near the coast later today, with winds weakening through the weekend.
Generally light winds and low seas are then expected into early next week.
Red flag conditions are not expected for the next several days.
Although locally heavy rain will fall over portions of our AL and Nrn tier GA counties rest of overnight into this morning. river gauges are expected to remain below flood stage for the next several days.
