No changes to the Day 1 Outlook. Receptive fuels and dry conditions persist across the Southeast, but light winds should mitigate widespread fire weather concerns. ...Georgia into the Carolinas... A mid-level short wave trough evident in current water vapor imagery and nearly collocated surface low will progress eastward into the Ohio River Valley through today. Gulf moisture return will be concentrated farther west along the lower MS River Valley with dry conditions and afternoon relative humidity in the 20-30% range across much of the Southeast. However, south/southeast winds will remain light at or below 10 mph through the afternoon across GA and the Carolinas where drier fuels are found, limiting a broader fire weather threat. ..Williams.. 11/18/2025 .PREV DISCUSSION... /ISSUED 1239 AM CST Tue Nov 18 2025/ ...Synopsis... Critical fire weather concerns are not expected for today across the country, though localized concerns may emerge across portions of the Southeast and southern Appalachians this afternoon. Early-morning satellite imagery depicts a weakening upper wave over the central Plains. This feature, along with an attendant surface low, will shift eastward into the OH Valley through this evening. Across the West, another upper wave continues to drift southward along the CA coast. Strong low-level winds are expected to accompany both of these systems, however, increasing showers/thunderstorms coincident with the breezy conditions will mitigate fire weather concerns. Elsewhere, surface winds are expected to remain sufficiently benign to limit the fire weather threat. ...Georgia into the Carolinas... Dry conditions are expected to continue across GA into the Carolinas for today. Southerly winds will help advect some returning moisture into the region, but ensemble consensus is that RH minimums in the 20-30% range will be common once again. Surface high pressure will limit wind speeds to mainly near/below 10 mph based on the 90th percentile of recent HREF/NBM runs. However, a few locations, especially at higher elevations, may see occasional gusts upwards of 15-20 mph that may support very localized fire weather concerns. ...Please see www.spc.noaa.gov/fire for graphic product... $$
