SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1140 PM CST Fri Jan 08 2021 Valid 101200Z - 111200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... General thunderstorms are possible Sunday from southern Texas into southern Louisiana. Severe weather is unlikely. ...Synopsis... A shortwave trough with cyclonically curved speed max will move east across TX and toward the lower MS Valley on Sunday, providing strong winds aloft and large-scale lift. Ahead of this trough, east/northeast surface winds will maintain a cool/stable air mass with high pressure, preventing any appreciable destabilization along the Gulf Coast. Models clearly show the surface low remaining over the Gulf of Mexico, with little if any SBCAPE over land. Despite this, southerly winds and moisture advection above the surface will likely result in weak elevated instability, supporting at least isolated elevated thunderstorms across much of southern and eastern TX and perhaps southern LA. ..Jewell.. 01/09/2021
