Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0753 PM CDT Thu Mar 12 2026 Valid 130100Z - 131200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast tonight. ...01z Update... Thunderstorm potential is diminishing quickly across the FL Peninsula early this evening. Boundary layer cooling will lead to weaker buoyancy over the next few hours and poor lapse rates do not appear particularly favorable for robust deep convection. Latest radar data exhibits shallow convection along the front, but only a few flashes of lightning remain with this activity. Across the upper MS Valley, exit region of strong midlevel jet will support weak elevated convection from eastern ND across MN into western WI tonight.

Even so, thunderstorms will remain quite isolated. ..Darrow.. 03/13/2026Read more
