SHORT TERM
(This afternoon through Monday)
Issued at 233 PM EST Sun Dec 3 2023

Surface analysis shows a pre-frontal trough across far southeast GA this afternoon with a cold front across northern portions of the state. A secondary dry cold front is currently cross the Mississippi River. The dry front looks to move through tomorrow, along with a wind shift to the NW.

The secondary front will also bring much drier and cooler airmass to the area. There is good potential for deep mixing tomorrow and with the gusty NW surface winds, dewpoints could be several degrees below the current forecast. This pertains to mostly fire weather concerns. If dewpoints are lower than currently forecasted, a Fire Danger Statement may be necessary.

LONG TERM
(Tuesday morning through next Saturday)
Issued at 233 PM EST Sun Dec 3 2023

The long term pattern will begin with mostly zonal flow aloft.
However, by Tuesday night, an upper trough will dig over New England and the Mid-Atlantic states. This may bring some very light rain/snow showers to the NE GA mountains. No accumulating snow is anticipated at this time, and precipitation probabilities are low. Colder temperatures are expected Wednesday, with daytime highs ranging in the 40s across extreme North GA to near 60 across southern portions of the CWA. Wednesday night will be the coldest night of the extended period, with low temperatures mainly in the 20s to near 30. Temperatures will begin to rebound to near normal late in the work week. Another upper trough is forecast to dig over the MS Valley by Fri night/Sat morning, with a chance of showers returning to the area Saturday.

Will need to keep an eye on fire weather for Thursday. Dry air will remain in place as daytime high temperatures begin to climb again. Additionally, SW winds will begin to increase, with gusts over 15 mph possible across portions of N GA. Right now Min RH values are forecast above critical thresholds but this could change as we get closer to the end of the work week.
