SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0150 AM CST Sun Mar 12 2023 Valid 141200Z - 151200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast on Tuesday. ...Synopsis and Discussion... Appreciable low-level moisture to support convection will likely remain confined along/south of a front extending from south FL and the Keys across the Gulf and into deep south TX. Convergence along this boundary is expected to remain generally weak, which should limit thunderstorm coverage over land. Still, isolated convection may develop Tuesday afternoon across parts of south FL and the Keys with diurnal heating. A couple of thunderstorms may also occur over deep south TX as modest lift associated with the glancing influence of a shortwave trough overspreads this region. Another upper trough will impact much of the western CONUS on Tuesday. Most guidance indicates that instability will remain negligible, with thunderstorm coverage probably remaining less than 10%. ..Gleason.. 03/12/2023
