Thunderstorms are unlikely through tonight. ....20z Update... No adjustments are needed as latest observations and short-term guidance suggest that thunderstorm potential will remain negligible over the CONUS through tonight. ...Guyer.. 02/28/2025 ..PREV DISCUSSION... /ISSUED 1015 AM CST Fri Feb 28 2025/ ....Synopsis and Discussion... An upper trough over Ontario and the Upper Midwest is forecast to further amplify today as it eventually encompasses much of the eastern CONUS. With a surface cold front having cleared the Gulf/Atlantic Coasts, dry and/or stable conditions are likely to preclude thunderstorms across the central/eastern CONUS through tonight. Farther west, a closed upper low will approach coastal southern CA through the period. While showers may occur across parts of this region as the upper low approaches, thermodynamic profiles are forecast to remain generally unfavorable for lightning production. $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
