The current stretch of mild weather will come to a peak today with a breakout of sunshine and temperatures jumping towards the 70 degree mark. A cold front, however, will push through the region later in the day and this will lead to tumbling temperatures during the overnight hours and set the stage for some wintry precipitation from tomorrow into tomorrow night. During the day on Thursday, there can be some rain, ice and/or snow in the DC metro region and then freezing rain is quite likely tomorrow night for awhile and there can be an ice buildup in some of the far northern and western suburbs. By Friday, temperatures should climb above the freezing mark leading to some residual plain rain for the area.

Today will be another mild day in the Mid-Atlantic region with periods of rain as low pressure pushes from the Upper Midwest towards the southeastern part of Canada. The current mild stretch will peak on Wednesday afternoon with the breakout of sunshine after a cloudy start and temperatures are quite likely going to reach 65-70 degrees in the DC-to-Philly-to-NYC corridor. The passage of a cold front later tomorrow will then bring about big changes in the temperature department in the overnight hours setting the stage for a winter weather event from later Thursday into early Friday. The winter weather event could include some snow accumulations; primarily, across the northern Mid-Atlantic and a potential significant buildup of ice in places like southern and central Pennsylvania.

It’ll stay quite mild again today, but rain is on the way for the mid-day and afternoon hours and it’ll continue into the evening as low pressure pushes by to our northwest. The warmest day of the week is coming on Wednesday ahead of the next cold front with temperatures likely to reach 70 degrees during the afternoon. Following the passage of the cold front, temperatures will tumble on Thursday and this could lead to some ice and/or snow in the DC metro region before an eventual changeover to plain rain on Friday.

It’ll be quite mild in the Mid-Atlantic region through mid-week, but then it turns much colder on Thursday and that cool down could be accompanied by some icing in much of the area. Temperatures today should make it into the 50’s and they’ll remain on the mild side on Tuesday, but it’ll become quite wet as well with a decent rainfall on the way from later tomorrow into tomorrow night. The warmest day of the week is likely to be on Wednesday ahead of the next cold front with temperatures likely to climb well up in the 60’s, but then big temperatures changes will take place by Thursday. Looking beyond the possible ice event later Thursday, numerous signs point to a continuation of winter weather conditions in the eastern states as we wind down the month of February and then flip over to March. In fact, there is a good chance for a very cold air mass to arrive in the east by early next week and it could be preceded by some snowfall.

The first half of the week will be much milder than recent days, but it’ll turn colder again on Thursday and there is a threat for some wintry precipitation from later Thursday into early Friday. Highs will be well up in the 50’s later today and 65 degrees is on the table by mid-week. A cold front crosses the region later Wednesday and sets the stage for a “cold air damming” setup from Thursday into Friday potentially resulting in some ice and/or snow before a changeover to rain.

A strong cold front has pushed through the region and winds will remain quite strong this morning in the Mid-Atlantic region. Temperatures will drop through the day following the early day highs and clouds will give way to sunshine for the mid-day and afternoon hours. After a cold and more tranquil night, Saturday will feature a reinforcing shot of cold air and this frontal passage will be supported by a strong wave of energy in the upper part of the atmosphere. As a result, there will be snow shower activity on Saturday in parts of the Mid-Atlantic/NE US and perhaps even a few isolated snow squalls. In addition, winds will become quite strong gusting past 40 mph in the DC-to-Philly-to-NYC corridor.

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.
