Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1138 PM CST Wed Nov 11 2020 Valid 131200Z - 141200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected Friday or Friday night. ...Synopsis... A progressive large-scale pattern will exist over the CONUS on Friday, with richer low-level moisture relegated to southern Florida and central/southern Texas. Thunderstorm potential will be spatially confined to just a few areas Friday/Friday night, with severe thunderstorm potential currently expected to be virtually nil. ...South-central Plains/Lower Missouri Valley... The potential for thunderstorms is expected to increase Friday night after sunset, initially across parts of southern/eastern Kansas, Oklahoma, and western North Texas. This elevated thunderstorm development will be related to increasing warm/moist advection atop a cold/stable boundary layer to the north of a southern Plains warm front. Thunderstorms may develop as far east-northeast as much of Missouri/northern Arkansas overnight. Severe thunderstorms are unlikely as quantities of elevated moisture/buoyancy are expected be too meager for meaningful hail production. ...Coastal Oregon/Washington... An amplifying shortwave trough and related frontal band are expected to develop inland across the region Friday afternoon. While a stronger low-topped thunderstorm or two near coastal portions of Oregon/southwest Washington cannot be ruled out Friday afternoon, the potential for severe thunderstorms currently appears low. ..Guyer.. 11/12/2020
