Subj : DAY3SVR: Nws Storm Prediction Center Norman Ok To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Wed Sep 24 2025 19:25:35 ACUS03 KWNS 241925 SWODY3 SPC AC 241924 Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0224 PM CDT Wed Sep 24 2025 Valid 261200Z - 271200Z ....NO SEVERE THUNDERSTORM AREAS FORECAST... ....SUMMARY... Scattered thunderstorms are likely across the Southeast and into the Carolinas on Friday. A few stronger storms may be possible near the coast from Georgia to North Carolina. ....Synopsis... A broad upper tough over the eastern CONUS is forecast to weaken before becoming cut off over portions of the Southeast Friday. To the west, an upper low will move slowly eastward settling over the Southwestern States into the weekend. A cold front will move offshore across the Mid Atlantic Coast and into parts of the Southeast Friday and Friday night. ....Southeast... As the cold front over the Southeast moves slowly eastward, a weak wave low should develop along it across portions of northern AL and western GA. Locally stronger convergence along the front and ahead of the weak low is expected to support scattered storms at the start of the period. Slow intensification of this activity is possible with scattered heating of the moist air mass. Moderate buoyancy, but modest vertical shear suggests a few multicellular clusters are possible as storm coverage gradually increases through the day. This would support some stronger downdrafts and sporadic damaging gust potential given high precipitable water content. The highest storm coverage is expected along the advancing front and near the coast across GA and SC where a few downbursts are possible. However, the limited vertical shear and very poor mid-level lapse rates lend low confidence in 5% coverage. ....Southwest... Beneath the weakening upper low, weak southerly flow will transport residual monsoon moisture northward over the southern Great basin and Four Corners. Widespread showers and thunderstorms are expected through the afternoon. Modest mid and low-level lapse rates will support some destabilization beneath the upper-level cold core despite clouds and ongoing showers/storms. While not overly strong, 30-35 kt mid-level flow could support a few stronger thunderstorms with severe wind potential owing to relatively high cloud bases. ...Lyons.. 09/24/2025 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
