SHORT TERM
(This afternoon through Tuesday)
Issued at 240 PM EDT Mon Mar 18 2024
The main driver of the sensible weather today into tomorrow will be a deep upper level trough currently extending from southeast Canada into the Lower Mississippi River Valley region. A surface boundary associated with the trough is moving southward through Georgia, with noticeably cooler and drier air behind. Dewpoints in the 20s have settled in across the northern tier. Highs this afternoon will be mainly in the 50s in north Georgia and 60s in central Georgia. Northwesterly winds have increased as the trough axis swings eastward towards the area, increasing to 15-20 mph with gusts as high as 25-30 mph. Locally higher gusts may be possible in the mid to late afternoon, but will not be widespread enough to warrant a Wind Advisory. Wind speeds will begin to diminish this evening, with gusts coming to an end after midnight.
As the upper trough axis moves through the area, 1000-500 mb thicknesses will decrease to as low as 528-540 dam across much of north Georgia, indicating the potential for well below average temperatures through the remainder of the short term period.
Temperatures overnight and into Tuesday morning are forecast to drop into the upper 20s roughly north of I-85 and into the low 30s to the south. As a result, a Freeze Warning remains in effect for portions of north and central Georgia. Some isolated locations in east- central Georgia may experience sub-freezing temperatures in the early morning hours as well. High temperatures tomorrow will rise into the upper 50s to the low 60s underneath mostly clear skies.
With dry northwesterly flow continuing to filter into the area, I opted to run on the low side of guidance for dewpoints. Dewpoints are forecast to be in the teens and low 20s throughout the day, with single digit values possible in the higher elevations of far northeast Georgia. As a result, minimum relative humidity values are forecast to range from 20-25 percent across the area on Tuesday afternoon and early evening. If 10-hour fuels are able to sufficiently dry out today, which appears likely with elevated winds and plenty of sunshine, a fire danger statement will likely be needed for Tuesday. 1000-500 mb thicknesses will increase as upper level ridging moves towards the Southeast and surface high pressure becomes centered over south Georgia. Lows early Wednesday morning will be warmer compared to Tuesday as a result, mainly in the upper 30s. Some locations in far north Georgia could approach freezing, and will need to be monitored in case another Freeze Warning is needed for these locations.

LONG TERM
(Wednesday morning through next Sunday)
Issued at 240 PM EDT Mon Mar 18 2024
A mid-/upper-level ridge and surface high pressure will keep conditions dry on Wednesday and Thursday. Will need to monitor the relative humidity forecast both days in regards to fire weather conditions, as the current forecast is for the upper-20 to upper-30 percent range. High temperatures both days will be in the upper 60s to mid-70s outside of the mountains.
Ensemble guidance indicates a 500mb shortwave trough traversing the Southeast on Friday, but guidance is clustering the low centers across the Gulf Coast and/or over the Gulf itself, so northward advection of warm, moist, unstable air over the CWA looks unlikely.
In addition, guidance is suggesting the development of a wedge across portions of north and central Georgia, which would further promote a stable airmass. As a result, have omitted thunder from the forecast at this time. The GEFS places the average area of low pressure farther north than does the EPS, evidenced by GEFS QPF being a few tenths of an inch greater than the EPS QPF overall. The current expectation is that rain showers will begin on Friday morning, continue through the afternoon, and shift eastward out of the CWA on Friday night. Friday high temperatures will be cooler than the previous two days -- generally in the mid-50s to mid-60s.
Dry conditions will return on Saturday and Sunday with lows in the upper 30s to lower 50s and highs in the mid-60s to lower 70s -- within a few degrees of normal.

VFR conditions continue at all sites. Gusts have largely begun to taper off though a few intermittent gusts 18-22kts may be possible up until 09z. Otherwise, NW wind are forecast to be 10kts or less through 12z. Around 16-18z winds will shift back to the west with speeds 7 to 10kts and will taper off after 00z.
