Discussion
There is growing likelihood for yet another heavy rain event in the DC metro region and it could include some strong thunderstorm activity as well. High pressure has pushed off the Northeast US coastline and a warm front will approach the area later today from the southwest. This front will stall out over the region on Friday and allow low pressure to track right along its boundary zone. While there can be a few showers and thunderstorms later today and tonight, the main rain event around here will come later Friday into Saturday with occasional heavy rain and possible strong thunderstorms. Given the already-saturated grounds in some spots, flash flooding may become a serious concern during this storm. The rain looks like it will linger through much of of the day on Saturday and perhaps even into Sunday; especially, along coastal sections as this unfolding July nor'easter will be a slow mover.
