Discussion
A strong cool front will pass through the region later today and it will be accompanied by numerous showers and embedded thunderstorms which can produce some heavy rainfall - some of the storms can reach strong-to-severe levels. A more comfortable air mass will arrive in the Mid-Atlantic region for the “Wednesday through Friday” time period and it will be anchored by strong high pressure that originated in southern Canada. By the weekend, a deep upper-level "negatively-tilted" trough is likely to form over the Upper Midwest and this will lead to an unstable and unsettled weekend around here with significant rainfall possible on both weekend days.
