High pressure will drift off the northeastern US coastline over the next couple of days and this will allow for some continued moderation in our temperatures. Moisture will push in our direction from the southern states late in the week and showers should break out here from late Friday into Saturday. A second and more important system is likely to throw rain our way late Saturday into early Sunday - some heavy at times - and then much colder air will follow for early next week. A reinforcing second blast of Arctic air will arrive here by the middle of next week. This mid-week Arctic frontal passage will have plenty of upper-level support which could result in snow showers or perhaps even snow squalls in some of the Mid-Atlantic region.

The Arctic air mass in control around here during the past couple of days will modify somewhat today and we’ll turn slightly milder for the second half of the week. By the end of the week, moisture will spread northeastward from the Deep South and showers are likely later Friday into early Saturday. By late in the weekend, a more important rain event is possible from Saturday night into Sunday and this system will usher in much colder air for the early part of next week. This initial shot of more Arctic air will likely be followed by a second blast at mid-week. Elsewhere, the rain (coast) and snow (inland) will continue to pile up over the next few days across California thanks to El Nino enhanced Pacific Ocean storms. Also, next week's initial Arctic blast will arrive first in the Upper Midwest and the playoff football game in Minneapolis on Sunday is likely to be played with temperatures near zero.

Arctic air continues to grip the region today, but it will ease during the second half of the week. By the end of the week, moisture will spread northeastward from the Deep South and rain is likely to affect the Mid-Atlantic late Friday and for parts of the upcoming weekend. Colder air will return by early next week which is looking quite cold across much of the nation.

What a difference a new year makes! The overall weather pattern has undergone an important change in the Mid-Atlantic region during the past several days and the warm temperatures of December will soon be missed. An Arctic blast arrives today from the northwest and it will bring the coldest air mass of the season into the region for the next couple of days with temperatures well below-normal for early January and overnight lows way down into the teens in many suburban areas. The Arctic chill eases later this week and then moisture will likely head in our direction from the Deep South by the end of the week. Elsewhere, a train of El Nino enhanced storms will slam into California this week alleviating somewhat their drought conditions and some of this activity could play a role in our weather here next week which is full of potential for storminess.

A colder weather pattern is now taking hold in the Mid-Atlantic region and we’ll experience much more seasonable temperatures for the foreseeable future. Along with the change to colder and drier weather, we’ll also experience more in the way of sunshine compared to the recent persistently cloudy stretch. There will be another cold frontal passage late Sunday which will usher in a true Arctic air mass for Monday and Tuesday. As a result, temperatures won’t climb higher than the 30’s for highs - maybe not even out of the 20's - and there will be a stiff NW wind causing even lower wind chill values.

A colder weather pattern is now unfolding for the Mid-Atlantic region and the first much more seasonable air mass arrives later today/tonight and it will remain much closer-to-normal temperature-wise right through the upcoming weekend. December has been a very warm month and one full of cloudy days; however, this pattern change will not only bring us colder and drier air, it will also allow for much more in the way of sunshine – at least for the next several days.

December has been quite warm and just full of cloudy days...today will be no exception. Temperatures should climb to near the 50 degree mark later today along with those persistent cloudy skies and showers could arrive after 4pm or so and then continue through the evening. It'll start to turn colder on Thursday as high pressure builds into the region and the return of more "normal" cold air will increase our chances for sunshine on Thursday, Friday and right through the weekend which will remain on the cold side. This late week cold shot signals an overall pattern change which will allow for more sustained cold air outbreaks in the Mid-Atlantic region during the month of January and perhaps even beyond.

Low pressure to our northwest today will push a warm front through the area and we’ll turn milder again for the mid-week time frame. A strong cold front will arrive on Thursday and its passage will usher in a cold air mass to begin the New Year. In fact, the overall weather pattern is currently undergoing a change that will allow for more sustained cold air in the Mid-Atlantic region during the month of January and perhaps even beyond.

A cold frontal system passed through the region last night and a large low pressure system will lift out of the southern Plains and into the Great Lakes region later today into Tuesday. The result here will be more rainfall and it should be just cold enough for ice pellets to mix in at times across the northern and western suburbs. Another low pressure system will pass northwest of our area late in the week and it will sweep another cold front to the east coast bringing a more sustained colder pattern change for the beginning of 2016.

The record high for today at Central Park is 63 degrees set in 1996 and it is certainly in jeopardy. In fact, temperatures are likely to climb to the 70’s by later in the afternoon. A cool front will slide through by tomorrow bringing slightly cooler air into the area, but it’ll stay well above normal for this time of year. It also stays quite unsettled as more rain should return to the area by tomorrow night and the rain threat will continue on each weekend day.
By Sunday, another significant warm surge will take place in the eastern US and more records could fall. Talk about a nation divided; however, at the same time the eastern states are warm, the western half of the country will be in the deep freeze. Some of that colder air will push across the Great Lakes region and into upstate New York and New England early next week and snow and ice could actually break out in those areas by Monday night or Tuesday. In fact, the threat for snow or sleet could extend into the NYC metro region as cold high pressure builds to the north.
One final note, the moon will be full on Christmas Day which is actually quite a rare event. The last time the full moon fell on December 25th was 1977, and it won't happen again until 2034.
