.SHORT TERM /THROUGH WEDNESDAY NIGHT/... Issued at 119 PM CDT Tue Sep 23 2025
A warm front remains over the area with a surface low over central Oklahoma and waves of upper level energy moving through. The surface low will shift over the area this evening, resulting in increased wind fields, including wind shear. Instability remains limited across the area due to widespread rain and cloud cover, but some clearing is occuring over the southwestern CWA, where dewpoints are higher than elsewhere at around 70F. MLCAPE should increase to 1,000-2,000 J/kg south of I-44 later this afternoon into the evening with effective shear of 40-50 kts and SRH of 200-300. Long arcing hodographs (including SE surface winds) will result in a tornado threat, but thinking that will be greatest along the MO/AR border where the greatest low level instability exists along a remnant convective boundary.
Overall expectations are for an uptick in convection later this afternoon and evening, with some convection become severe given ample fields for organized severe weather. Hail up to golf ball size will be possible (mainly over the southwestern CWA) and damaging winds along and south of I-44. A low end (5%) tornado threat exists near the MO/AR border.
By late evening, stronger convection should exit the southeastern CWA, but light rain, fog, and at times drizzle will linger into Wednesday night or perhaps early Thursday. This is due to the upper trough remaining over the area. Look for highs in the 70s Wednesday and lows in the 50s Wednesday night.

.LONG TERM /THURSDAY THROUGH MONDAY/... Issued at 119 PM CDT Tue Sep 23 2025
After precip exits the area Wednesday night or Thursday morning, the rest of the long term is dry. Look for a gradually warning trend from highs in the 70s Thursday to the low to mid 80s Saturday, where it will remain into at least early next week.
