222 ACUS01 KWNS 060041 SWODY1 SPC AC 060039 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0639 PM CST Wed Feb 05 2025 Valid 060100Z - 061200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS IN SOUTHERN/CENTRAL KY TO FAR NORTHERN TN... ...SUMMARY... A couple tornadic storms, along with isolated damaging winds and large hail, will be possible overnight into early morning Thursday across parts of Kentucky and Tennessee. ...KY/TN... A low-amplitude shortwave trough over the Mid/Lower MO Valley will progress east across parts of the Midwest tonight. Strong tropospheric flow attendant to this wave will overspread the northern periphery of a warm-moist sector advancing north from the TN Valley. This will induce weak cyclogenesis overnight within the pronounced baroclinic zone. Low-level warm theta-e advection will strengthen later this evening, with mainly elevated convection occurring north-northeast of the surface front. Still, some potential will exist for near surface-based storms across the baroclinic zone, along with a couple supercells. A separate band of broken convection may form in the early morning as a cold front emerges near the developing surface cyclone. Enlarged low-level hodographs, coupled with pronounced elongation in the mid/upper levels, could foster a couple sustained surface-based supercells within this regime across parts of southern to central KY and far northern TN. The categorical risk has been increased to a level 2-SLGT for the overnight/early-morning tornado potential. ..Grams.. 02/06/2025 $$
