It turns milder today in the Mid-Atlantic region and then it looks like we’ll have to deal with a very active frontal passage from late tomorrow night into Friday morning. Temperatures will surge on Thursday ahead of the approaching strong cold front and showers will become numerous by tomorrow night. In fact, some of the rain can fall heavily for a brief time from later tomorrow night into early Friday and there can be a thunderstorm or two mixed into the picture. Of more concern, however, is the likelihood for powerful winds from late tomorrow night into early Friday and there can be potentially damaging wind gusts; especially, immediately after the front pushes through the region.

It looks like there will be a very active frontal passage in the Mid-Atlantic region and Northeast US from later Thursday night into early Friday. Temperatures will surge on Thursday ahead of the strong cold front and showers will become numerous by Thursday night. In fact, some of the rain can briefly fall on the heavy side later Thursday night into early Friday and there can be a thunderstorm or two mixed into the picture. Of more concern, however, is the likelihood for powerful winds from later Thursday night into early Friday and there can be potentially damaging wind gusts (i.e., power outages are on the table); especially, near and along the eastern seaboard from Virginia-to-Maine.

The Arctic air mass that arrived this weekend remains in complete control this morning with very low temperatures throughout the Mid-Atlantic region as we start off the day on Tuesday. A full day of sunshine should boost temperatures well up into the 30’s and then it’ll turn milder on Wednesday. Temperatures will then surge on Thursday ahead of the next strong cold front and the (brief) warm up will be accompanied by strong winds and numerous showers. It turns moderately chilly behind the front on Friday and for the weekend to follow.

High pressure will push into the region today on the heels of yesterday’s snowfall and it will remain much colder-than-normal for the middle part of February. There can be a snow shower or two during the morning hours with some continued instability in the atmosphere. Given the very cold conditions, any snow shower can produce a quick dusting and some slippery spots on the roads. It stays quite cold tonight and Tuesday and turns noticeably milder on Wednesday. On Thursday, the next strong cold front will approach the region leading to an active weather day with possible heavy rain and strong thunderstorms. Temperatures will surge on Thursday, but the warm up will brief as much colder air returns on Friday and the weekend to follow.

After a mild start to the weekend, a pair of cold frontal passages ushered in much colder air to the Mid-Atlantic region that will stick around into Tuesday. Precipitation broke out late last night along the frontal boundary zone and changed to all snow before sunrise in the DC-to-Philly-to-NYC corridor as Arctic air filtered into the region. Snow will continue at varying rates for awhile longer today – likely into mid-day or early afternoon - aided in large part by a strong upper-level jet streak and mid-level frontogenesis. There can be additional accumulations of a couple of inches on untreated surfaces. Temperatures will hold in the low-to-mid 30’s and then drop into the teens during the overnight hours and they’ll remain well below-normal on Monday and Monday night. After a cold day on Tuesday and a milder Wednesday, very active weather will come to the area later Thursday and Thursday night possibly to include heavy rainfall and strong thunderstorms along with a dramatic, but brief spike in temperatures.

The day started off quite mild in the Mid-Atlantic region, but the passage of a pair of cold frontal systems will bring about big changes in the overall temperature pattern for the next few days. Temperatures will likely peak by early afternoon and then drop slowly later this afternoon as an Arctic air mass begins to filter into the region following the passage of these two cold fronts. An upper-level trough of low pressure will then dig into the eastern US tonight and low pressure - aided by a strong jet streak aloft - will form along the Arctic frontal boundary zone. Precipitation will break out later tonight in the DC-to-Philly-to-NYC corridor and Sunday morning is quite likely to feature accumulating snow throughout the region which can last into the mid-day hours in most areas. Very cold conditions will follow on Sunday night, Monday, and Monday night with Valentine’s Day high temperatures generally confined to the 20’s - well below-normal for mid-February. The Arctic chill will disappear at mid-week and then it turns much milder on Thursday, but that warm up looks brief and it may be accompanied by some heavy rainfall with the arrival of the next strong cold front.

It stays mild in the Mid-Atlantic region into the beginning of the weekend, but an Arctic front will slide through the area on Saturday and its passage will bring about much colder conditions for Sunday, Monday and Tuesday. Low pressure is going to form along the Arctic frontal boundary zone by tomorrow night and this system should generate accumulating snow in the Mid-Atlantic region from late Saturday night into Sunday likely on the order of a coating to a few inches in most spots. The core of the Arctic air mass will move overhead by Monday and temperatures on Valentine’s Day will be way below-normal for the middle of February. The Arctic chill wanes by mid-week and then signs point to a big time warm-up by late next week although it is likely to be accompanied by some rain by week’s end.

It stays mild in the Mid-Atlantic region for today and into the beginning of the weekend, but an Arctic front will reach the area tomorrow and its passage will bring about much colder conditions for Sunday, Monday and Tuesday. Low pressure is likely to form along the Arctic frontal boundary zone by tomorrow night and this system should generate some snow in the region from late Saturday night into Sunday. While the odds are against anything significant, snow accumulations of a coating to a couple of inches are on the table later in the weekend. The core of the Arctic air mass will move overhead by Monday and temperatures will be way below-normal for the middle of February. Looking ahead, the Arctic chill will wane by mid-week, and there are signs for a big time warm-up by late next week although it could be accompanied by rain at week’s end.

It stays mild in the Mid-Atlantic region into the beginning of the upcoming weekend, but an Arctic front will reach the area on Saturday and its passage will bring about much colder conditions for Sunday, Monday and Tuesday. Low pressure is likely to form along the Arctic frontal boundary zone by Saturday night and this system could generate some accumulating snowfall in the Mid-Atlantic region from late Saturday night into Sunday. The core of the Arctic blast will move into the region on Monday with temperatures on Valentine’s Day likely to be way below-normal for the middle of February. The Arctic chill wanes by mid-week and then signs point to a big time warm-up by late next week.

The next few days will be relatively quiet in the Mid-Atlantic region and still pretty mild compared to earlier in the week. A weak cold front will pass through the area tonight, but it will have little impact on surface temperatures with another fairly mild day expected on Friday. After a mild beginning to the weekend, an Arctic cold front will head into the eastern states from northwest-to-southeast and it will tend to slow down on its arrival. Snow or rain changing to snow is likely to develop late Saturday night and continue into Sunday morning as a wave of low pressure forms along the cold frontal boundary zone. Much colder air will push into the area on Sunday and it’ll stay quite cold through the early part of next week.
