.DISCUSSION... (This evening through next Thursday) Issued at 1230 PM CDT Fri Sep 5 2025
The latest surface analysis places a cold front just north of the I-40 corridor, with visible satellite imagery showing high cirrus streaming across the region. Drier air has already begun to move in behind the front, noted by dewpoints in the upper 50s and lower 60s in southeast Missouri. The front is expected to slow and stall right along the I-40 corridor through late afternoon. South of the boundary, the atmosphere will destabilize with up to 2500 J/kg of MLCAPE on hand. Coupled with 30 to 35 knots of bulk shear, convective initiation will begin within the next 3 to 4 hours and likely initiate in west Tennessee. A Slight Risk (2/5) has been slightly expanded for areas along the Tennessee River, where lift, instability, and shear will be maximized this afternoon and evening. A Marginal Risk (1/5) remains in effect for the rest of the Mid-South.
Damaging winds and large hail remain the main threats with a low risk (
