SHORT TERM /Today through Thursday/.
A trough deepening over the eastern half of the country was helping to push a cold front into northwest GA this morning. This front should move through north and central GA today. Moisture is limited so no precipitation is expected Behind the front. low relative humidity and windy conditions will combine with drying fuels to heighten fire danger today However. relative humidity values look like they will remain above 25 percent this afternoon. So with northwest winds of 15 to 20 mph with gusts to near 30 . and fuel moisture below 8 percent . a Fire Danger Statement has been issued for the afternoon. The Fire Danger Statement replaces the Fire Weather Watch. The Wind Advisory will be continued for today also.
Overnight low temperatures will drop into the 30s over much of the forecast area. Lows near freezing still look reasonable for the far northeast and the Freeze Watch has been upgraded to a Freeze Warning Elsewhere. patchy frost is possible toward Thursday morning as wind speeds drop off.
Critical fire conditions are possible for Thursday as relative humidity values are expected to drop into the low 20s for much of east central GA. This will continue to be monitored.
LONG TERM /Thursday Night through Tuesday/.
Friday will bring weak ridging aloft as surface high pressure shifts eastward from the spine of the Appalachians to just offshore of the Carolinas. Low-level moisture will increase across western Georgia through the day as the surface high pressure circulation drives southerly flow across the CWA. As a result, the greatest potential for fire danger conditions on Friday will be across the eastern portion of the CWA, where relative humidity is forecast to fall to 23% to 25% for several hours in the afternoon.
Models continue to be in good agreement with the timing and big picture of the weekend system. A 500-mb trough will eject northeast across the ArkLaTex and TN Valley over the course of late Friday night through Saturday afternoon. However, the track of the associated surface low -- and the placement of its warm front across the CWA -- are more uncertain at this point. The GFS is still suggesting strong low-level flow (40-50 kts at 925 mb and 50-60 kts at 850 mb) out of the south to southwest, as well as ample instability, so strong to severe storms will be a concern during the daytime hours. The placement/progression of the warm front will largely dictate where the threat for severe storms will be maximized. Have a slight chance to chance of showers and a slight chance of thunderstorms for late Saturday night into early Sunday morning, as the upper trough axis and moisture push off to the east.
In addition to the potential for strong to severe storms, heavy rain will also be a concern as progged PWATs of 1.5-1.7 inches across central Georgia are near the daily maximum per sounding climatology. Fortunately, 6-hour QPF through the event should be manageable given the recent dry conditions and normal to below- normal streamflows. That said, any locally heavier or longer- lasting rainfall -- especially across north Georgia and metro Atlanta -- could lead to localized flash flooding and quick rises of creeks, streams, and rivers.
Monday and Tuesday look to be sunny to mostly sunny, dry, and warm courtesy of a stout upper ridge building across the eastern half of the CONUS.
AVIATION . 06Z Update . VFR conditions through the period. A dry cold front will increase mid/high clouds mainly for the northern sites this morning then clearing. Winds initially light southwest increasing from the west by 10z then more enhanced northwest winds increase during the day to 18-20 kts gusting close to 30 kts.
