There will be very active weather from later tonight into early Friday in the Mid-Atlantic/Northeast US associated with the approach and passage of a strong cold frontal system. Temperatures are surging today ahead of the strong cold front and showers will become numerous from later tonight into early Friday and there can be a strong thunderstorm or two mixed into the picture. Of more concern, however, is the likelihood for powerful winds and there can be potentially damaging wind gusts; especially, in the time period surrounding the arrival and passage of the strong cold front. In the hour or so immediately behind the frontal passage, the pressure will spike, winds will shift in direction, and gusts can reach their highest levels. Temperatures will drop through the day on Friday after early day highs and the winds will die down tomorrow night. A reinforcing shot of cold arrives on Saturday and it will be supported by a very strong upper-level disturbance resulting in scattered snow showers/squalls and wind gusts past 40 mph.

The powerful winds of late Thursday night and early Friday will diminish on Friday night; however, the next strong system will produce 50+ mph wind gusts on Saturday in the northeastern quadrant of the nation and there can be snow showers and even heavier snow squalls. After that, there are signs for a big time warm up in the eastern states in the Monday, Tuesday and Wednesday time period with temperatures likely to climb into the 50’s and 60’s. There are also signs, however, that next week’s warm up will be a temporary break from winter weather and that there will be a resurgence of winter weather as we get to late next week and beyond. In fact, an evolving stratospheric warming event and the trending pattern of Pacific Ocean teleconnection indices suggest that winter’s wrath could hang around well into the month of March across the eastern states with additional cold air outbreaks and multiple new snow threats.

Temperatures will surge today ahead of a strong cold frontal system and showers will become numerous later this evening. Some of the rain later tonight can fall briefly on the heavy side and there can be a strong thunderstorm or two mixed into the picture. Of more concern, however, is the likelihood for powerful winds later tonight into tomorrow morning and there can be potentially damaging wind gusts with scattered power outages certainly on the table. The time period of greatest concern will be in the hour or two immediately following the passage of the surface cold front associated with an expected surge in pressure and a shift in wind direction. The frontal passage is most likely going to take place somewhere between about 1 AM and 6 AM. Moderately chilly air will follow the frontal passage and then a reinforcing shot of cold arrives on Saturday supported by a strong wave aloft that can result in some snow shower activity across the northeastern states and more very windy conditions.

It looks like there will be a very active frontal passage in the Mid-Atlantic region and Northeast US from later tomorrow night into early Friday. Temperatures will surge on Thursday ahead of the strong cold front and showers will become numerous on Thursday night. In fact, some of the rain can briefly fall on the heavy side 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 and there can be potentially damaging wind gusts with scattered power outages certainly on the table. The likely time period of greatest concern will be in the hour or two immediately following the passage of the surface cold front associated with an expected surge in pressure and a shift in wind direction. The likely location of greatest concern for these possible damaging wind gusts will be along coastal sections from Virginia-to-Maine. Moderately chilly air will follow the early Friday frontal passage and then a reinforcing shot of cold arrives on Saturday supported by a strong wave aloft that can result in snow shower activity across the northeastern states.

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.

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.
