- Low chances of thunderstorms late Wednesday night through Thursday.

-Warming trend expected this weekend with next chance of rain early next week.

NEAR TERM

(Rest of Today and Tonight) Issued at 1014 AM CST Tue Feb 24 2026

Surface high pressure centered over southern AL will translate southeastward today keeping skies clear through the early afternoon. This in addition to a developing surface low east of the Rocky Mountains will promote mild WAA via a broad area of enhanced southwesterly flow over the southeastern CONUS. This will allow high temperatures to reach into the l50s this afternoon in addition to increasing dewpoints from m10s to m20s. A developing mid-level shortwave associated with an upper-level low over southern Canada will bring marginal height falls and consequently increasing cloud cover to the area late this afternoon. This cloud cover in addition to winds of 10-15kts at the sfc should prevent large amounts of cooling overnight, with low temperatures expected to remain mild in the l40s.

SHORT TERM

(Wednesday through Thursday) Issued at 1014 AM CST Tue Feb 24 2026

Largely zonal flow will take precedence across much of the southeastern CONUS by Wednesday, reinforcing rather dense cloud cover over most of the region. As the aforementioned surface high continues to translate eastward over the Atlantic, south- southwesterly flow will persist across the TN valley through Thursday allowing high temperatures to climb into the u50s-l60s on Wednesday and m60s-u60s on Thursday. Temperatures will remain mild Wednesday night thanks to continued cloud cover with lows in the l50s expected.

A mid-level shortwave trough will begin to develop east of the Rocky Mountains and shift southeastward on Wednesday, beginning to influence conditions in the TN Valley starting late Wednesday afternoon. Forcing associated with this trough will allow low to medium precipitation chances (20-60%) to return late Wednesday afternoon into Thursday morning. Precipitation chances will increase (70-80%) through the early afternoon on Thursday ahead of an approaching cold front. With adequate 0-6km bulk shear (45-55 kts) in place, some organized convection may develop Thursday afternoon, though largely meager instability (50-150 J/kg SBCAPE) should prevent a severe threat from materializing.

LONG TERM

(Thursday night through Monday) Issued at 958 PM CST Mon Feb 23 2026

Convection will taper off in wake of the front Thursday evening/night and a drier air mass will filter into the area by Friday morning. However, other than a drop in dewpoints there will be little change to the air mass as we return in a fairly zonal pattern aloft. As a result, a gradual warming trend will take place through the weekend as afternoon highs will reach the low to mid 60s on Friday and the upper 60s to lower 70s both Saturday and Sunday, with southerly flow returning. Low chances for rain will return early next week as a weak shortwave will approach the region from the west.

AVIATION

(18Z TAFS) Issued at 1029 AM CST Tue Feb 24 2026

VFR flight weather conditions are forecast through tonight. Lower ceilings of 015-025agl (MVFR) will develop NLT 14Z, with a very low chance of -SHRA toward the end of the period. Have left this out of both KMSL and KHSV TAFs due to the very low probability.
