The weather this week will be quiet across much of the eastern two-thirds of the nation and relatively mild for the middle portion of December. The warmer-than-normal weather this week will likely peak on Thursday in the Mid-Atlantic region with temperatures probably reaching into the 60’s in the DC-Philly-to-NYC corridor. A different story is possible next week, however, as the overall pattern shows some signs of turning colder and potentially stormy in the northeastern part of the nation.

After a chilly day on Sunday, it’ll turn a bit milder today and stay warmer-than-normal through the week. High pressure will be in control in much of the eastern US for the next several days although there will be a couple of weak frontal systems to deal at times. A stronger cold front will head this way this weekend and that is likely to result in a cool down by the end of the weekend. One final note, record high temperature were indeed set on Saturday in DC (70 degrees), Philly (68 degrees) and New York City’s Central Park (66 degrees).

The weather has been rather chilly in the Mid-Atlantic and Northeast US during the past few days, but a major league warm-up is coming on Saturday. In fact, the surge of warmth tomorrow will quite likely result in record highs in many spots including perhaps the DC, Philly and NYC metro regions. Another factor on Saturday will be the winds which will intensify substantially ahead of an incoming strong cold front perhaps gusting up to 55 mph or so. Showers are likely to accompany this frontal system on Saturday in the eastern states and there can even be some strong thunderstorm activity. It’ll turn considerably colder on Sunday following the frontal passage, but then warmer conditions will return next week. For today, the warm air will explode northward through the Mississippi Valley and a severe weather outbreak is on the table which includes the threat of tornadoes.

A warm up begins today in the Mid-Atlantic region, but it really intensifies on Saturday as winds will increase substantially as we begin the weekend from a southwesterly direction. In fact, winds on Saturday can gust past 50 mph and temperatures should soar towards the 70 degree mark around here which would threaten the December 11th record of 68 degrees set in 1979. Late day and evening showers are likely to accompany the approach of the incoming strong cold front and there can even be a strong thunderstorm as well in some spots. Following the passage of the strong cold front, it’ll turn noticeably colder on Sunday with afternoon highs likely confined to the 40’s. Looking ahead, much of next week will turn out to be warmer-than-normal across the eastern two-thirds of the nation as strong high pressure ridging develops over the Great Lakes.

Today will be a cold and dry day in the Mid-Atlantic region with plenty of cloud cover, but a big time warm up is coming by the weekend ahead of the next strong cold front. The surge of warmth expected on Saturday is likely to come with strong southwesterly winds and record high temperatures in much of the eastern US including perhaps the DC, Philly and NYC metro regions. Temperatures could actually soar to the 70 degree mark around here which would break the record of 68 degrees set back in 1979. It’ll turn noticeably colder on Sunday following the passage of a strong cold front. However, the bulk of next week looks to be quite warm across the eastern two-thirds of the nation as strong high pressure ridging develops over the Great Lakes.

While the weather today is pretty cold in the Mid-Atlantic and Northeast US with a touch of snow in some spots, a big warm up is coming by the weekend and the bulk of next week looks to be on the warm side of normal as we head towards the middle part of December. In fact, the surge of warmth expected this Saturday is likely to come with record high temperatures in much of the eastern US including along the DC-to-Philly-to-NYC corridor. Temperatures could actually soar towards the 70 degree mark in DC and Philly and climb into the middle 60’s in NYC – all well above-normal for this time of year and all would threaten record highs. This surge of record-breaking warmth will come ahead of the next strong cold front which can produce severe thunderstorms on Friday in the Mississippi Valley and even some strong thunderstorm activity later Saturday in the eastern states.

Weak low pressure will push to a position off the Mid-Atlantic coastline by later today and it could produce a touch of snow in some spots at times, but its overall impact will be very limited. This system features little support in the upper atmosphere, a limited amount of moisture, and any intensification of the surface low is going to wait until it is well off the east coast. It remains cold on Thursday, but will turn much milder again by the beginning of the weekend. In fact, a surge of warmth on Saturday could bring record high temperatures to the metro region with temperatures soaring towards 70 degrees…turns colder again on Sunday.

A strong cold front passed through the region in the overnight hours with scattered showers and some very gusty winds. After a cold, dry and much less windy day on Tuesday, weak low pressure will push to a position off the Mid-Atlantic coastline by early tomorrow morning. This system has little support aloft, limited moisture, and should only be able to produce a touch of snow in portions of the Mid-Atlantic region on Wednesday. It remains cold on Thursday, but will turn much milder again by the beginning of the weekend.

A strong cold front will arrive in the eastern states late today and its passage will set the stage for some snow at mid-week in the Mid-Atlantic region and Northeast US. It’ll turn very windy and much milder today just ahead of the front along with a few rain showers. Temperatures will drop sharply in the overnight hours behind the front as the strong winds shift to a northwesterly direction. After a cold, dry and much less windy day on Tuesday, low pressure will push to a position off the Mid-Atlantic coastline by early Wednesday morning. The fresh cold air mass that arrives shortly following the passage of the front will maintain its ground at mid-week allowing for primarily snow in the Mid-Atlantic/Northeast US and minor accumulations are on the table.

A strong cold front will arrive in the eastern states later today and it’ll turn very windy and much milder ahead of it and then sharply colder behind it during the overnight hours. The winds can gust past 40 mph later in the day from a southwesterly direction and then again later tonight following the frontal passage from a northwesterly direction. After a cold and dry day on Tuesday, low pressure will push from the south-central states to a position off the Mid-Atlantic coastline on Wednesday bringing the chance of some snow which can be mixed with rain and/or sleet at times. Some snow accumulations are possible in the region with this mid-week system likely in the range of a coating to a couple of inches.
