A cold front will close in on the region today bringing with it a good chance of showers; especially, later in the afternoon and early tonight. Skies should clear after midnight as a colder air mass pushes into the Mid-Atlantic region and a stiff NW breeze will develop following the passage of the cold front. The next couple of days will feature windy conditions, daytime temperatures well below-normal for late April despite some sunshine on each day, and overnight lows in the 30’s in most suburbs. Some modification will take place in temperatures during the late week period and the weekend should begin on a quiet and mild note.

High pressure off New England will continue to produce an onshore flow around here limiting our temperatures somewhat today and resulting in an abundance of clouds. Showers will develop later tonight and on Tuesday as a cold front approaches the region and much cooler air will move in for the mid-week period. Highs on Wednesday will likely be limited to the lower 50’s and it’ll be quite windy and then late night temperatures will drop down into the 30’s.

The warming trend that began at mid-week will continue today and afternoon temperatures are likely to peak near the 70 degree mark. It does turn a bit cooler on Saturday, but then a surge in temperatures on Sunday could result in afternoon highs not far from the 80 degree mark. Looking ahead, we are not quite done yet with the cold shots from Canada and another such air mass featuring below-normal temperatures will arrive here by the middle of next week and stick around into the subsequent weekend.

Temperatures could surge to 80 degrees this Sunday in parts of the Mid-Atlantic region, but as has been the case for much of the spring, this next warm up will not necessarily stick around for an extended period. In fact, signs point to another shot of cold air for the Mid-Atlantic region by the middle of next week and teleconnection indices suggest we may have to deal with unusually chilly air masses right into the first part of May with overnight lows in the 30’s.

A weak frontal system will approach the region later today, but with little impact and high pressure will re-establish itself in the Mid-Atlantic region on Friday. As a result, the warming trend that began yesterday will continue for the next couple of days and the nice weather pattern looks like it’ll continue into early next week. We are not quite done with the cold shots, however, as another air mass featuring below-normal temperatures is destined to arrive here by the middle of next week.

After a very chilly start to the week, a warming trend and a nice stretch of weather will begin today as high pressure builds into the area. Temperatures will climb into the 50’s this afternoon and then into the 60’s on Thursday ahead of the next cool front which will be rather weak and inconsequential. As a matter of fact, temperatures should climb to the 70 degree mark on Friday and it’ll stay relatively mild this weekend as well.

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 70 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. Around here, a soaking cold rain is coming from later today into late tonight as a strong storm pushes to the northeast near and along the east coast. There is an outside chance that snow or ice pellets mix at times during this storm in some of the western and northern suburbs. It remains unusually chilly on Tuesday with partial sunshine and windy conditions. High pressure will return for the mid-week and it’ll turn milder with 70 degree highs returning late in the week.

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 in the upper 30’s 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. Low pressure will try to organize on Monday near the Mid-Atlantic coastline and it could produce some chilly rain around here and even some snow across interior sections of the Mid-Atlantic/NE US.
