Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1149 PM CDT Sun Mar 09 2025 Valid 111200Z - 121200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are possible across far southwest California Tuesday afternoon/evening. Severe storms are not expected. ...Synopsis... Generally low-amplitude westerly mid/upper flow will overspread the Plains and Southeast ahead of a shortwave upper trough moving into the Southwest. At the surface, a prior cold frontal passage deep into the Gulf and high pressure over the eastern Gulf/Southeast will result in a dearth of boundary layer moisture east of the Rockies for much of the period. Further west, a surface low offshore southern CA will weaken as it moves east over southern CA during the afternoon/evening. Cool temperatures aloft beneath the upper trough will support steep lapse rates and weak instability (MUCAPE generally less than 300 J/kg). Isolated thunderstorms will be possible offshore and may persist inland across a small part of southwest CA. ..Leitman.. 03/10/2025
