Overview
The hottest weather of the spring so far is on the way for the Mid-Atlantic region with Friday, Saturday and Sunday promising to be noticeably different than what we’ve experienced in recent days. The transition to this uncomfortable weather pattern will actually begin later tonight with the arrival of low pressure and its associated warm front and there can be downpours in the Mid-Atlantic region along with embedded thunderstorms. Following the passage of the warm front, it’ll turn noticeably warmer and more humid later Thursday and the warm up will intensify on Friday and likely peak on Saturday afternoon with temperatures well up in the 90’s in many locations. A cool front closes in on the eastern seaboard late in the weekend bringing with it a renewed chance of showers and thunderstorms.

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.

By the late weekend, the next cool front will slide slowly eastward into the eastern states and it is likely to bring with it more shower and thunderstorm activity from late Sunday into Sunday night. This frontal system may get hung up for a bit on Monday possibly extending the threat of showers and thunderstorms into the early part of next week; however, temperatures should become more comfortable after the warmest three-day period so far this season.
