A classic fall storm setup will come together Monday night into Tuesday night across much of the East coast. The storm prediction center has already issued a RISK area for Maryland, NJ, PA, DE, NY, and VA for Tuesday afternoon. The combination of strong upper air dynamics coupled with abundant moisture could lead to wind damage across many states.
There are currently two players I am monitor at this hour. A developing low pressure center over Louisiana, with plenty of gulf moisture, is beginning to intensify and move north. At the same time a trough over North Dakota is digging south into the upper Midwest. As the trough over North Dakota moves southeast it will lift the moisture out of the Gulf coast states north into Maryland and the Mid Atlantic. The trough will continue to strengthen as it digs south increasing the winds in the Mid Atlantic starting Monday night and going into Tuesday. Bands of rain will stream in from south to north bringing heavy rain to the region. During Tuesday afternoon a few thunderstorms could develop in the quick south to north flow and any storm that becomes strong could tap into very strong winds a loft, dragging them to the ground. There is the threat for some wind damage across the area Tuesday afternoon and evening.
