Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0650 PM CST Sun Dec 25 2016 Valid 260100Z - 261200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Organized severe thunderstorms are not forecast through early Monday morning across the Lower 48 states. ...Synopsis... A mature deep-layer cyclone over the north-central states will develop northeastward into the Upper Midwest by early Monday. A cold front will push eastward across the western part of the Cornbelt and to the western Great Lakes states while the trailing portion of the boundary stalls over TX. A low-topped convective band will continue to progress east-northeastward across IA and MO but a stable layer near the surface will likely inhibit momentum transfer of strong gusts to the surface during the evening. Farther south, as the upper system continues to become increasingly displaced from the Ozarks southward into north-central TX, a lessening in forcing for ascent and weak buoyancy will act to limit storm intensity but maintain an overall organized convective structure, prior to weakening further later this evening into the overnight. ..Smith.. 12/26/2016Read more
