KEY MESSAGES

Updated at 1019 PM CDT Tue Oct 27 2026

- Medium chances of showers and a few storms will return to the forecast Saturday into Sunday.

NEAR TERM

(Rest of tonight and Wednesday) Issued at 1019 PM CDT Tue Oct 27 2026

Increasing clouds were observed over NW AL this evening as a weak upper wave moves across the area, bringing a plume of moisture aloft over the TN Valley. While this won't result in any rain due to dry low level conditions, this will keep temperatures a few degrees warmer overnight and should keep larger dense fog concerns at bay. With that said, current dewpoint depressions are only 3-5 degrees in some locations, so we will not rule out a low chance for dense fog before the night is over.

Dry weather will persist on Wednesday as high pressure stays anchored at the sfc while south to southwest flow aloft in the mid to upper levels keeps temperatures on the warmer side of seasonal norms. Highs will top out in the low to mid 70s, approaching even the upper 70s across NW AL. Clouds should thin during the morning leading to sunny skies tomorrow afternoon.

SHORT TERM

(Wednesday night through Friday) Issued at 1019 PM CDT Tue Oct 27 2026

The weather pattern will change little over the Southeast during the short term, but the larger synoptic pattern will set the stage for active weather over the weekend. High pressure aloft will build over the Gulf while the remnants of what is currently Tropical Storm Vance moves across western TX and into the Midwest. We won't really begin to see any impacts from these changes until late Friday when moisture advection from the Gulf increases over the area and clouds begin to move in from the west. The main story for us in the meantime will be increasing temperatures, with highs rising to the upper 70s on Thursday and even warmer on Friday when the ridge axis centers over the TN Valley. While we won't break record temps (87 at HSV and 86 at MSL), highs in the lower 80s will certainly feel warm for this time of year.

LONG TERM

(Friday night through Tuesday) Issued at 1019 PM CDT Tue Oct 27 2026

Over the weekend, a quick pattern transition will take place, with the 5h and 8h ridges shift east of the region. This will allow a shortwave to enter the Ozarks and Mid South on Saturday into Sunday. The greatest UVVs will be on Sunday for the local area with our greatest shower chances. Only a slight chance of a thunderstorm exists at this point with limited instability. QPF of 0.4-1.3 inches with the highest amounts west of I-65 looks OK for now. With the surface/wedging remaining across the Lee of the Appalachians into the southeast U.S., a cool and fairly stable lower atmosphere is expected. Chances wane late Sunday, with low chances of light rain or perhaps some drizzle look favorable given shallow isentropic ascent over the cooler airmass that arrives. By Monday into Tuesday, minor upper ridging takes places and shifts into the Southeast U.S. ahead of a strong deepening upper trough in the Plains states. Southerly flow will increase Monday into Tuesday. A line of showers and thunderstorms will take shape in the lower MS Valley Tuesday in advance of the trough and cold front. But the deepening and slow nature of the upper low may delay the arrival of widespread precipitation until Wednesday.

AVIATION

(06Z TAFS) Issued at 1135 PM CDT Tue Oct 27 2026

With observations showing dewpoint depressions becoming smaller, went ahead and put in MVFR fog for a few hours before sunrise at both terminals. Beyond that, VFR conditions will prevail at both terminals for the rest of the forecast period.
