A late season nor’easter continues to produce accumulating snow across interior sections of the Mid-Atlantic and Northeast US and windy, cold weather in the DC-to-Philly-to-NYC corridor. This system will lift into New England this morning and high pressure will gradually fill its shoes in our area late today into Wednesday. Milder weather returns later in the week and we’ll likely be flirting with the 75 degree mark again for highs by Friday afternoon.

A late season coastal storm will bring heavy rain to the DC-to-Philly-to-NYC corridor from later today through tonight, strong winds and potential flooding to coastal sections and accumulating to snow to interior, higher elevation locations of the Mid-Atlantic/Northeast US. In fact, it is not out of the question that some of the northern and western suburbs of the big cities along I-95 see ice pellets or even snow mixed in at times during this unfolding coast storm. An unusually chilly air mass is in place across the northeastern part of the nation, jet streaks will form at multiple levels of the atmosphere, and a vigorous disturbance aloft will all contribute to the formation of a significant storm that will have a variety of impacts over the northeastern quadrant of the nation. Cold air outbreaks from Canada into the central and eastern states have continued unabated in recent weeks and it looks like they will continue into late April and likely the early part of May.

Here we are in the second half of April and significant accumulating snow is on the table for later today and tonight across interior sections of the Mid-Atlantic and Northeast US.

Snow will actually fall during this storm as close to us as the western parts of Virginia and Maryland with accumulations quite likely.

A cold front passed through the region last night and has ushered in cooler air to the Mid-Atlantic region for the end of the work week. An even stronger front will arrive late tomorrow possibly accompanied by showers and thunderstorms and its passage will usher in a colder air mass for Sunday. In fact, temperatures could start off the day on Sunday near the 40 degree mark in some spots and they’ll be confined to the 50’s for afternoon highs – quite a difference from the 80’s of the past couple of days.

Temperatures soared into the 80’s on Wednesday in much of the Mid-Atlantic and in many spots this was the first reading this season at those levels. A repeat performance is in store for today with afternoon highs again likely to be in the 80’s across much of the region, but this time, showers and strong thunderstorms will accompany the warmth. A cold front is sliding this was from the Ohio Valley and an even stronger cold front will arrive late Saturday with more showers and possible thunderstorms. That mid-weekend frontal passage will usher in a colder air mass for Sunday and much of next week will be on the cool side across the northern US. A coastal storm will form early next week and it is likely to result in accumulating snow for the interior sections of the Mid-Atlantic and Northeast US.

A cold front will head into the eastern US today and it’ll stay very warm ahead of it with afternoon high temperatures near 80 degrees. The chance of showers will increase during the afternoon as the front approaches and there can be a late day or early evening strong thunderstorm. It’ll turn cooler on Friday behind the front, but still pretty nice as we close out the work week. Another front will cross the region on Saturday night and its passage will usher in a colder air mass for the second half of the weekend. In fact, high temperatures on Easter Sunday are liable to hold in the 50’s despite plenty of sunshine as high pressure takes control and much of next week looks to be on the cool side.

The weather pattern continues to be active today as a strong cold front slides eastward into the Mid-Atlantic region and low pressure will form near the east coast along the frontal boundary zone. As a result, more rain will fall today in the region and there can be a thunderstorm or two mixed into the picture. After the surface low pressure system pushes away, a large scale upper-level trough will edge overhead on Friday and this system will produce cool and unsettled conditions on Friday afternoon and evening with the likelihood of more shower activity. It stays cool on Saturday as well and there can be an additional shower or two as it’ll remain somewhat unstable with chilly air in the upper part of the atmosphere. Looking ahead, a much warmer pattern will evolve next week in the eastern states and we’ll likely return to the 70’s by next Tuesday afternoon.
