Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1156 PM CST Wed Jan 08 2025 Valid 091200Z - 101200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast through Friday morning. ...Synopsis... A large, positive-tilt upper trough will extend from the Four Corners into Baja CA early today, and will move eastward into the Plains through Friday morning. Strong southwest flow aloft will spread east across the southern Plains and into the lower MS Valley, with nearly 100 kt at 500 mb within the leading speed max. At the surface, a cool and stable air mass will remain due to high pressure, though warming above the boundary layer will occur. The strongest theta-e advection will occur over much of southern to eastern TX through 00Z, spreading across LS and MS into Friday morning. While shear will be very strong, only elevated instability will exist over land, north of a developing surface low over the northwest Gulf of Mexico. MUCAPE of 100 to 250 J/kg appears reasonable over parts of TX and extending late into LA, with scattered convective shower and thunderstorms possible. It is unlikely that instability will be strong enough for any hail risk given poor lapse rates aloft. ..Jewell/Wendt.. 01/09/2025
