.SYNOPSIS... A cold front moves through the region today bringing cooler and drier air to the north and west and a chance of showers and thunderstorms to the south and east. Mainly dry conditions are expected during the upcoming work week, with below normal temperatures to start, gradually warming as the week goes on.
&&
.NEAR TERM /THROUGH TONIGHT/... Key Message(s):
- Front moving through with strong temperature gradient in place, cooler in the north, warmer in the south.
- Scattered showers and storms expected along the front with highest chances south of I-20.
Cold front is moving through the forecast area this morning. Deep layer moisture remains relatively high, above 1.5 inches across the entire area and is expected to remain high ahead of the front with drier air moving in aloft behind it. Shower and thunderstorm coverage today will be highly dependent on the exact progression of the front with destabilization, and as a result highest chance for showers and storms, expected this afternoon. Highest potential for sbCAPE to exceed 1000 J/kg will be south of I-20 where greater than 50 percent of members favor this moderate destabilization. As a result, highest convective coverage expected in the southeastern portion of the forecast area. Precipitation may be moderate to potentially heavy at times, especially where the front meets the sea breeze with hires guidance indicating this will be possible around the I-95 corridor and areas east. Significant uncertainty in the temperature forecast for today due to the cold front. A tight temperature gradient will be in place across the area today with the far northwestern portion of the forecast area struggling to reach 80 and the southeastern portion of the area approaching 90. Convection will diminish tonight with drier air continuing to move in overnight. Lows tonight in the low to mid 60s.

.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... Key message(s):
- Cool and dry conditions for much of the region to start the new work week. Winds may be breezy at times due to a tight pressure gradient.
Weak upper troughing will dominate the region during the period. This combined with surface flow out of the northeast around high pressure to our north will result in mainly dry conditions and temperatures below seasonal values. Moisture will be confined to the coast, though a shower or two cannot be ruled out across the Eastern Midlands, mainly along and east of I-95. Winds may be breezy at times due to a tight pressure gradient between the aforementioned high pressure to our north and an inverted trough off the coast. Daytime temperatures should be in the upper 70s to lower 80s both days with overnight lows in the upper 50s to mid 60s.
&&
.LONG TERM /WEDNESDAY THROUGH SATURDAY/... Key message(s):
- Continued dry with temperatures warming to near normal values to close out the work week.
Strong high pressure and continued weak troughing aloft maintain a northeasterly flow through much of the extended. Moisture is shunted out of the region due to a reinforcing trough with PWATs at or below an inch for much of the period. Despite troughing aloft, a warming trend is expected, with temperatures returning to near normal values on Thursday and Friday. Long range guidance suggest that below normal height anomalies will develop next weekend resulting in lower temperatures once again though the dry weather continues.
&&
.AVIATION /12Z SUNDAY THROUGH THURSDAY/... VFR conditions in place with chance of showers and storms this afternoon into evening.
Expect VFR conditions at all terminals as a cold front moves through the area. This afternoon showers and storms will develop near the front and while the coverage is uncertain, have included a prob30 group for tsra at all the terminals for the potential. As the front continues to move east, lingering low level moisture tonight will lead to restrictions developing and increasing northeast winds. Highest confidence in ceiling restrictions at OGB.
EXTENDED AVIATION OUTLOOK...A cooler and drier air mass will settle over the region early next week behind the front.

.CAE WATCHES/WARNINGS/ADVISORIES... SC...None. GA...None.
