SPC Mar 30, 2022 0730 UTC Day 3 Severe Thunderstorm Outlook

SPC 0730Z Day 3 Outlook Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0208 AM CDT Wed Mar 30 2022 Valid 011200Z - 021200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are possible across the Florida Peninsula as well as from the Texas Panhandle into Oklahoma and North Texas on Friday. ...Synopsis and Discussion... A stable, post-frontal airmass is forecast to cover much of the central and eastern CONUS early Friday, anchored by an area of high pressure centered over the MS Valley. This area of high pressure is expected to drift eastward throughout the day. Some modest moisture advection is anticipated over south TX ahead of a shortwave trough moving into the Plains. Isolated thunderstorms are possible from the TX Panhandle eastward across OK and north TX as this shortwave moves through. However, the higher dewpoints and greater buoyancy will be displaced south of the stronger forcing for ascent, limiting the severe potential. Isolated thunderstorms are also possible across the FL Peninsula as a weakening cold front slowly moves southward across the region. Moderate southwesterly flow aloft will be in place over the peninsula, supporting the potential for a few stronger storms. Uncertainty regarding coverage merits omitting severe probabilities with this outlook. ..Mosier.. 03/30/2022 Read more CHECK UPDATE ZOOM GRAPHIC
