12:20 PM | *Downpours later tonight in the transition to the warmest weather so far this season in the Mid-Atlantic region* — Arcfield Weather

Details

Low pressure and its associated warm front now over the Midwest will push eastward to the Mid-Atlantic region later tonight and this system is likely to generate showers and thunderstorms from late this evening into the wee hours of the morning on Thursday. Some of the rain that falls can be heavy at times. The surface low pressure system will be supported aloft by a pretty healthy “vorticity maxima” that moves directly over the Mid-Atlantic region. The batch of rain will push off the coast early tomorrow and mostly cloudy skies should give way to partial sunshine by afternoon.

In the afternoon on Thursday, it’ll turn noticeably warmer and more humid in the Mid-Atlantic region and the warm up will intensify on Friday.  In fact, temperatures on Friday afternoon should reach the mid or upper 80’s with 90 degrees possible in the DC metro region.  The hottest day is liable to come on Saturday when temperatures could climb into the middle 90’s in a good part of the DC-to-Philly-to-NYC corridor.  Much of the next two days look to be rain-free, but that kind of scenario changes later in the weekend.
