Discussion
A potent system will cross the Great Lakes later today at the same time a front to our south begins to advance northward as a warm front. The combination of these systems - along with loads of available low-level moisture - will result in an increasing unstable atmosphere from later tonight into Friday. While there can be an isolated shower or thunderstorm late today or early tonight, the main action time period, I believe, will be from about the wee hours of the morning into mid-day or early afternoon on Friday when showers and thunderstorms are likely to become more numerous. Any late night and early-to-mid Friday storm can be strong and downpours are on the table…watch out for the possibility of flash flooding. High pressure will then begin to build into the region later Friday night and there is reasonable hope that the weekend actually features back-to-back rain-free days in the Mid-Atlantic region along with comfortably warm temperatures.
