SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1125 AM CST Wed Jan 06 2021 Valid 071200Z - 081200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS FAR SOUTHEASTERN LOUISIANA AND AREAS JUST OFFSHORE FROM THE ALABAMA AND FLORIDA PANHANDLE COASTS... ...SUMMARY... Thunderstorms are possible Thursday across the Southeast, with very low/conditional threat for a brief tornado mainly from the mouth of the Mississippi eastward to just south of the Florida Panhandle coast. ...Synopsis... A complex/amplified flow field aloft is progged over the U.S. this period, with the main feature of interest being an upper low that will advance eastward across the southeastern quarter of the country through the period. Elsewhere, a second/substantial trough crossing the eastern Pacific will near the Pacific Northwest Coast late. At the surface, a weak low will shift eastward from the central Gulf Coast area during the day, and then across north Florida and into the southeastern Atlantic overnight. Meanwhile, a cold front -- trailing from a low that will remain offshore -- will reach the Pacific Northwest Coast overnight. ...Far southeastern LA east along the Florida Panhandle Coast... Strong low-level warm advection, atop a stable boundary layer, is expected across the Southeast Thursday, as the upper cyclone and attendant/weak surface low advance. While favorably strong/veering flow through the lower troposphere will precede the low, it appears increasingly unlikely that any appreciable surface-based CAPE will develop inland. Thus, the MRGL risk area is being adjusted southward, largely confined to areas just offshore, where a brief tornado cannot be ruled out. ..Goss.. 01/06/2021
