Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1146 PM CDT Thu Mar 20 2025 Valid 211200Z - 221200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not forecast today. ...Synopsis... A northwest flow regime will exist across the CONUS today, with multiple embedded waves. In general, minimal thunderstorm activity is forecast due to a relatively stable air mass due to high pressure. One such high will be situated over the Southeast and into the Gulf through the period, with minimal moisture return into southern TX. Another surface high will be centered over the Great Basin for much of the period. That said, thunderstorm chances will be limited to a small part of the Pacific Northwest, and from southeast SD across IA and into IL. Both areas will be beneath their respective shortwave troughs, with cool temperatures aloft supporting weak convection. ..Jewell/Lyons.. 03/21/2025
