NEAR TERM

(Tonight) Issued at 1257 PM CST Wed Nov 26 2025

Not much change in previous thinking. Obs indicate northwest winds gusting at 15-22kt at this hour with dew points falling into the 20s and 30s. The sky has cleared and expect winds to slacken abruptly after sunset upon the boundary layer decoupling as surface high pressure drops southeast into the Ozarks tonight. The only fly in the ointment are high clouds that will increase toward daybreak associated with a weak upper level wave. The GFS is actually generating 0.01 QPF in northwest AL, but believe the atmosphere will be far too dry to support measurable precipitation. That being said, will advise the next shift to watch this trend closely.

SHORT TERM

(Thursday through Friday night) Issued at 935 AM CST Wed Nov 26 2025

Deep layer northwest flow will result in a dry and quiet weather forecast through Friday. Any high clouds that arrive late tonight will exit quickly early Thursday with temperature advection in low levels becoming more neutral during the day, and remaining fairly neutral through Friday as the surface high migrates east into the OH and TN valleys. 5h flow becomes a bit more zonal as well, with southerly flow developing across the Plains in advance of the next trough digging south through the Rockies. High temperatures will only reach the upper 40s to around 50 in valley areas on Thanksgiving Day (lower 40s atop the Cumberland Plateau). After a hard freeze in the middle 20s Friday morning, highs only reach the middle to upper 40s in valleys on Friday afternoon (only upper 30s atop the Cumberland Plateau).

LONG TERM

(Saturday through Tuesday) Issued at 1257 PM CST Tue Nov 25 2025

Update... There are large uncertainties in the models regarding a window of wintry precipitation Sunday night and again Tuesday night in northwest AL and southern middle TN. The forecast will include low chances of -SHSN in these instances, but at this time, it is far too early to put alot of weight into this forecast. Deterministic model runs indicate very dry sounding profiles. Stay tuned to further updates.

Previous Discussion... One more dry day on Saturday as high pressure will remain the dominant weather feature -- through increasing cloud cover will cap any potential heating and keep high temperatures in the mid 50s. A pattern change is coming late this weekend as high pressure quickly scoots off to the east on Saturday and another trough swings from the Central/Southern Plains into the Mid Mississippi and Ohio Valley. This will force a cold front through the Tennessee Valley and Deep South. Ahead of this front, southerly winds will help to advect in some return flow moisture from the Gulf. Forcing from the trough and along the front will generate light rain showers Saturday night, that will become much more numerous (60-70% chance) Sunday and Sunday night as the front passes across the region. Rainfall totals up to 1" seem plausible with this initial round of precipitation. A brief "lull" will occur on Monday, before an additional storm system will form along the Gulf -- bringing widespread showers and a few storms (60-80%) Monday night into Tuesday. This slower moving system may bring some locally heavy rainfall on the order of 1-2" which could result in some minor rises on creeks and streams. Dense cloud cover and high rain chances will keep high temperatures on the cool side in the upper 40s.

AVIATION

(18Z TAFS) Issued at 1031 AM CST Wed Nov 26 2025

VFR flight weather conditions are forecast. Northwest winds will gust at 15-20kt through 00Z, then diminish quickly below 10kt. Mid and high level ceilings at or above 120agl (VFR) will arrive late tonight lasting into Thursday morning.
