Subj : DAY2SVR: Nws Storm Prediction Center Norman Ok To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Mon Dec 30 2024 06:34:23 ACUS02 KWNS 300634 SWODY2 SPC AC 300632 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1232 AM CST Mon Dec 30 2024 Valid 311200Z - 011200Z ....NO SEVERE THUNDERSTORM AREAS FORECAST... ....SUMMARY... Isolated thunderstorms are possible from the Outer Banks into southern New England late Tuesday into early Wednesday. Severe thunderstorms are not expected. ....Synopsis... A compact shortwave trough is forecast to move from the OH Valley northeastward into southern New England on Tuesday. An attendant surface low will take a similar path throughout the day while gradually occluding, reaching western NY by late Tuesday night/early Wednesday morning. An associated cold front is expected to push from the Mid MS/Lower OH Valleys eastward through the remainder of the OH Valley, the TN Valley, and Southeast States. By Wednesday evening, a surface low generated by secondary cyclogenesis at the triple point will likely be over the Delmarva Peninsula vicinity, with the associated cold front extending from this low southwestward through the central Carolinas, southern GA, and the western FL Peninsula. Continued eastward progress will take this front off the East Coast and through all but south FL by early Wednesday morning. Limited low-level moisture and attendant buoyancy is anticipated ahead of this shortwave and its associated cold front, precluding thunderstorm development across much of the eastern CONUS. Some deeper convective cores are possible along and ahead of the cold front across the middle OH Valley Wednesday morning. A few lightning flashes are possible, but current expectation is for overall coverage to remain less than 10 percent. A greater risk for thunderstorms is possible from the NC Outer Banks into southern New England from Tuesday evening into Wednesday morning. Here, strong warm-air advection within the warm conveyor could result in a few elevated storms deep enough to produce lightning. ...Mosier.. 12/30/2024 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
