The influence of high pressure off the New England coast will fade this afternoon as low pressure near the Georgia coast becomes the main feature on the weather map. Low pressure is beginning to impact the Middle Atlantic states with cloudiness and breezy conditions. Temperatures this afternoon are on the cool side with readings only in the low to mid 60s. Rainfall will be light this afternoon with occasional showers expected. More widespread rain showers will move into the region overnight and during the day on Thursday. The heaviest rain will likely fall during the day on Thursday and into the evening hours. 1 to 2 inches of rain can be expected across the region with isolated higher amounts. Rain showers may persist into the morning hours on Friday before the sky begins to clear on Saturday afternoon. Along with the cool temperatures and rainfall, we can expect gusty winds from the northeast as the center of low pressure moves to our southeast and off the Virginia coastline. Winds may gust over 30 m.p.h. at times, and coastal flooding may occur on the western shore of the bay due to the onshore flow.
