000 ACUS02 KWNS 291702 SWODY2 SPC AC 291701 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1101 AM CST Sun Jan 29 2023 Valid 301200Z - 311200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast on Monday. ...Synopsis... A cold, continental air mass will continue to sag slowly southeastward from KY to the northwest Gulf coast on Monday, and a diffuse boundary will extend east-west from the northern Gulf coast to the southeast Atlantic coast. Aloft, west-southwest flow will persist from northern Mexico to the Mid-Atlantic, and a midlevel low will dig south-southeastward near the southern CA coast. Some shallow convection is expected near the southern CA coast, but buoyancy magnitude/depth will be very marginal for thunderstorms. Isolated thunderstorms may continue through the day along the diffuse boundary across the Gulf/southeast Atlantic coastal areas. Forecast soundings show weak-moderate buoyancy and straight hodographs which could support some storm organization. However, forcing for ascent will weaken with time and storm coverage is expected to remain isolated at best. Farther west, there will be a low chance for elevated thunderstorms across parts of OK/TX/AR with weak buoyancy rooted near 700 mb, and in association with subtle speed maxima ejecting east-northeastward during the day and then again early Tuesday morning. The midlevel convection could produce brief bursts of sleet in OK and a mix of sleet/freezing rain closer to the front, but buoyancy profiles will be marginal for charge separation/lightning production. ..Thompson.. 01/29/2023 $$
