Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0143 PM CST Thu Dec 03 2020 Valid 032000Z - 041200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... The risk for severe thunderstorms is low across the U.S. through tonight. ...Discussion... No change has been made to the previous convective outlook. ..Smith.. 12/03/2020 .PREV DISCUSSION... /ISSUED 1030 AM CST Thu Dec 03 2020/ ...Gulf Coast... A highly amplified large-scale pattern will persist through tonight, including a slow eastward evolution of a currently closed trough over the Ozarks toward the Mid-South through tonight. In association with richer moisture, scattered thunderstorms are expected to be most common over the open Gulf of Mexico waters off of Louisiana/Mississippi/Alabama and eventually off the Florida Panhandle tonight, but a few thunderstorms will also be possible over inland areas of the region this afternoon and tonight in vicinity of a northward-extending surface trough. Organized severe storms are unlikely. While a stronger storm or two could conceivably occur near coastal Louisiana (Plaquemines Parish) or near coastal parts of Mississippi/Alabama this evening into the overnight, latest thinking continues to be that inland destabilization will be limited and that the stronger/more organized storms will likely remain offshore through late tonight.
