SPC 1630Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1031 AM CST Wed Nov 24 2021 Valid 241630Z - 251200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are possible this evening and overnight from parts of the southern Plains into the Ozarks and mid Mississippi Valley. ...East/southeast Texas and southern Plains/Ozarks... Influenced by amplifying belts of split westerlies, a southeastward-moving cold front will approach the region late tonight/early Thanksgiving morning. A relatively moist air mass preceding the front along with increasing forcing for ascent including frontal uplift will contribute to increasing thunderstorm coverage from late-evening onward, initially across eastern Oklahoma and north Texas including the DFW Metroplex vicinity, and subsequently broader parts of the Ozarks/ArkLaTex and east/southeast Texas overnight. It is possible that a few stronger/more organized storms may materialize late tonight across a broad part of east-central/southeast Texas including the I-35/I-45 vicinities. This would be influenced by thunderstorms occurring immediately near the front and perhaps within a zone of pre-frontal confluence where boundary layer inhibition will be relatively weak. While sufficient, albeit modest, buoyancy and moderately strong low-level/deep-layer shear could support some weak/transient supercells and other semi-organized storms capable of small hail/gusty winds, the potential for severe thunderstorms is currently expected to remain low. ..Guyer/Gleason.. 11/24/2021 Read more LIVE: spc.noaa.gov
