KEY MESSAGES

Updated at 850 PM CDT Wed Apr 29 2026

- Medium to high chances of rain showers and perhaps a few thunderstorms Friday night. Storm total rain amounts of around 0.5" forecast

- A much cooler air mass will arrive this weekend, with daytime highs in the mid to upper 60s and overnight lows in the 40s.

NEAR TERM

(Today) Issued at 306 AM CDT Thu Apr 30 2026

An outflow boundary yesterday evening pushed northward into N AL providing an area of lift that resulted in showers and thunderstorms. These have now pushed northeast into GA. While the cold front has pushed south of the local forecast area, lingering showers continue to move eastward this morning. However, as an upper level jet streak shifts overhead, the forecast area becomes situated under the right exit region, an unfavorable area for precip. Satellite imagery shows this with an area of clearing across western TN. This area of subsidence is helping push the showers further to the south and east.

For today, a cooler and drier airmass will filter in from the north. With the upper level pattern more zonal, the cloud cover should remain through the day keeping afternoon highs only in the upper 60s to lower 70s.

SHORT TERM

(Thursday night through Saturday) Issued at 850 PM CDT Wed Apr 29 2026

High pressure to north will promote dry amd cool conditions again Thursday night as lows drop back into the 40s. Clouds will begin to increase on Friday as an area of low pressure will move eastward along the northern Gulf Coast. Would expect mostly dry conditions through the afternoon on Friday, but clouds will limit heating and highs will peak in the upper 60s once again. The aforementioned storm system will clip the Tennessee Valley Friday night, bringing medium to high (50-80%) chances for showers and a few thunderstorms (capable of producing some wetting rains of around one-half inch). The system will quickly depart on Saturday morning, with a cooler, drier air mass to follow -- and highs reaching the mid 60s in most locations.

LONG TERM

(Saturday night through Wednesday) Issued at 850 PM CDT Wed Apr 29 2026

A sharper trough will move through the region Saturday night, bringing a cooler, drier air mass into the Tennessee Valley for the later half of the weekend. High pressure at the surface will promote dry, mostly sunny days, but northwest flow will knock highs back into the low to mid 60s on Sunday and overnight lows into the lower 40s Sunday night. The upper-ridge axis will build eastward into the area early next week, as a pronounced warming trend will take place as temperatures return to seasonable levels in the upper 70s to lower 80s Monday through Wednesday.

AVIATION

(06Z TAFS) Issued at 1125 PM CDT Wed Apr 29 2026

VFR conditions will be the predominant flight category at each terminal through the period. However, some -SHRA passing across the region early Thursday may drop ceilings and visibilities to MVFR levels briefly between 06Z-10Z and have added a TEMPO to highlight this. Winds will also become gusty out of the NNE between 15-20 kts in the late morning and afternoon, before weakening after sunset.
