Subj : DAY1SVR: Day 1 Convective Outlook To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Wed Apr 09 2025 00:57:25 ACUS01 KWNS 090057 SWODY1 SPC AC 090055 Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0755 PM CDT Tue Apr 08 2025 Valid 090100Z - 091200Z ....NO SEVERE THUNDERSTORM AREAS FORECAST... ....SUMMARY... Organized severe weather is not expected through Wednesday morning. Isolated strong storms remain possible over the next few hours in South Florida and the Keys as well as western South Dakota. ....Synopsis... A shortwave trough continues to approach the Florida Peninsula this evening. A weak surface boundary that is currently offshore may provide some focus for thunderstorms tonight. Another shortwave trough in Montana is responsible for isolated strong convection moving into western South Dakota. This activity may continue another couple of hours before weakening. ....South Dakota... The low-level airmass is quite dry; however, moisture is sufficient for isolated convection on the southern fringe of the shortwave trough. Small hail may occur with this activity, but the dry boundary layer is more likely to support strong to potentially marginally severe wind gusts. Activity should weaken over the next couple of hours and coverage will remain too isolated for adding severe probabilities. ....South Florida/Keys... The approach of the shortwave trough may promote a modest increase in convection along and near the surface boundary. Given diminishing surface temperatures and increase MLCIN, storms will become increasingly elevated with time. A strong gust could occur with the strongest storms, but this potential should remain spatially limited. ...Wendt.. 04/09/2025 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
