Discussion
A soaking rain event is on the way for the first part of the weekend. Strong high pressure has pushed off the east coast and this will open the door for moisture to head this way from the Mississippi and Ohio Valleys. A strong upper-level wave of energy will help to generate surface low pressure over the Ohio Valley later today and then a second system will form nearby on Saturday. This second system will become the focus area for significant rainfall and heavy rain is possible here from late tonight into tomorrow afternoon. A thunderstorm is also possible during this soaking rain event. On Sunday, some sunshine will return to the Mid-Atlantic region, but it'll be rather chilly with strong NW winds.
