KEY MESSAGES

Updated at 958 PM CST Mon Feb 23 2026

- Very cold tonight with overnight lows in the upper teens to lower 20s. A warming trend will then begin on Tuesday.

- Low to medium chances of showers Wednesday evening increase to high chances on Thursday, with low chances of thunder late Wednesday night through Thursday.

NEAR TERM

(Today) Issued at 229 AM CST Tue Feb 24 2026

Clear skies and calm winds have allowed for decent radiational cooling allowing temps to drop into the low 20s. Cooling of a few more degrees is forecast by sunrise, yet the the absence of wind will keep apparent temperatures close to real temperatures.

Through the day, surface high pressure will rotate through the TN Valley keeping skies clear and turning surface flow to the SSW. This will allow for mild WAA with highs rebounding to the low 50s this afternoon. Slight moisture return will also occur rising dew points from the mid teens to the mid 20s through the day. Zonal flow aloft will allow additional cloud cover to filter in through the afternoon from a weak shortwave to our NW.

SHORT TERM

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

Generally zonal flow aloft will evolve by Tuesday night across the Deep South as high pressure slides off the south and east. A shortwave trough will begin to develop along the leeside of the Rockies on Wednesday and shift eastward toward the Tennessee Valley Wednesday night into Thursday. Ahead of this feature, cloud cover will increase steadily across the area late Tuesday night through the day on Wednesday. Despite the cloud cover, southerly flow should help to push high temperatures into the lower 60s by the afternoon.

The aforementioned shortwave will dive SE into the lower Mississippi Valley on Thursday, pulling a cold front into the Mid South and Tennessee Valley. Low-medium (30-60%)chances for rain showers will return to the forecast late Wednesday night into early Thursday morning ahead of the front. More widespread showers and storms (80-90% chance) are forecast during the day on Thursday, as the front finally pushes into the region. More than sufficient bulk shear values of 40-55 kts will support some organized convection, but instability appears to be fairly meager. LREF probs indicate 20-40% of exceeding 100 J/kg of SBCAPE and only around 10-15% chance of exceeding 200 J/kg of SBCAPE. Factoring in the poor lapse rates, any storms that do develop should be pretty limited in magnitude. However, given the aforementioned shear profile, a couple of locally strong storms might not be out of the question.

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

(06Z TAFS) Issued at 1103 PM CST Mon Feb 23 2026

VFR conditions will prevail at both terminals through the period underneath a mostly clear sky. SW winds will increase late Tuesday morning through the afternoon hours.
