Discussion
Vigorous upper-level low pressure will push into the eastern states over the next 24 hours or so and this will result in some of the chilliest air so far this season to the Mid-Atlantic region and Northeast US. As this system pushes east, atmospheric instability will bring us lots of clouds today and perhaps a few late day showers, maybe a rumble of thunder. The colder air mass filters into the region later tonight from the northwest-to-the-southeast. High temperatures for the next couple of days will likely be confined to the lower 50’s which is colder-than-normal for this time of year and frost will be possible in suburban locations during the late night/early morning time periods of Tuesday/Wednesday/Thursday. Looking ahead, noticeably milder weather will return by week’s end and the upcoming weekend.
