SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 1229 AM CST Fri Jan 08 2021 Valid 101200Z - 111200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... General thunderstorms are possible from parts of southeast Texas into southern Louisiana. Severe weather is unlikely. ...Synopsis... A shortwave trough will move east across TX and toward the lower MS Valley on Sunday, providing strong southwest flow aloft along with height falls. Ahead of this trough, a cool/stable air mass due to high pressure will exist, and will prevent any appreciable destabilization. Models indicate the surface low associated with this trough will remain over the northern Gulf of Mexico, thus there is little chance of SBCAPE developing over land. However, weak elevated instability is expected to develop from southeast TX into southern LA, supporting general thunderstorm activity. ..Jewell.. 01/08/2021
