Thunderstorms with an isolated damaging wind/tornado threat may occur Thursday from coastal North Carolina into parts of the Mid Atlantic. ....Synopsis... An upper-level low will deepen as it moves from the central Appalachians to the eastern Great Lakes on Thursday. A surface low will deepen slightly as it moves up the eastern slopes of the Appalachians. This will pull low-level moisture westward across eastern North Carolina and eastern Virginia into the Mid-Atlantic. ....Eastern North Carolina into the Mid-Atlantic... A line of strong to isolated severe storms will likely be ongoing at the beginning of the period from eastern Pennsylvania into southern Virginia. Ahead of this line of storms, weak instability is expected to develop, potentially as far west as far northern Virginia and far western Maryland. Have modified the western extent of this Marginal Risk to account for the expected western/northern extent of the warm sector ahead of the cold front. Isolated damaging wind gusts will be the primary threat, but strong low-level shear may also support a tornado. ....Western Pennsylvania... Beneath the upper-level low, some isolated hail threat may exist during the afternoon. Steepening mid-level lapse rates due to cooling temperatures aloft will result in some instability during the afternoon with sufficient shear for storm organization. Extensive cloud cover should limit surface heating and thus the threat for large hail. However, if some clearing/greater instability can develop in a corridor across western Pennsylvania, a few stronger storms may be capable of marginally severe hail. This trend will be monitored for potential hail probabilities in later outlooks. ...Bentley.. 10/29/2025 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
