A cold front passed through the region last night and today will be on the chilly side with a stiff NW wind making it feel even colder than the actual air temperatures. Another weak low pressure system could produce a bit of rain on Christmas Day and then a significant winter storm is likely to have an impact at the end of the week. There is potential for substantial icing around here by later Friday and Friday night with a strong high pressure system to our north acting as an important source of cold air through the event.

While the nation’s mid-section enjoys rarely ever-seen sustained warmth for the next few days, the northeastern states will continue to experience plenty of winter weather right into the early part of January. One system is bringing some accumulating snow today to the northern Mid-Atlantic region and Northeast US and some interior higher elevation locations will receive several inches. Another storm system is likely to threaten the Mid-Atlantic region and Northeast US on Friday with significant accumulating snow in some areas and substantial icing in others. A key player at the end of the week will be a strong high-pressure system over southeastern Canada which will act as an anchor for low-level Arctic air that can lead to frozen precipitation throughout the Mid-Atlantic region and Northeast US.
Looking ahead to next week, the winter weather pattern is likely to continue across the northeastern states with two major-league Arctic air outbreaks on the table. Both of these Arctic air masses will have originated up across the northwestern part of Canada where temperatures on Monday morning bottomed out at -67.7°F... reportedly the lowest temperature in Canada since January 1999…in other words, get ready, next week’s Arctic invasions might be quite noteworthy.

Low pressure to our north will produce some accumulating snow in the morning of up to a couple of inches and then a mix of rain and snow is likely around mid-day…precipitation winds down in the early-to-mid afternoon hours. After clearing skies tonight, the mid-week looks to be dry and chilly in the NYC metro region and then there can be a touch of light precipitation on Thursday, Christmas Day, from another “clipper” system that moves from northwest-to-southeast. A more impactful low pressure is likely here at the end of the week with significant snow and/or ice on the table as strong high pressure positioned to our north acts as a source of cold air for the northeastern states.

Low pressure to our north will produce occasional rain in the area during the morning hours and there can be some clearing skies by the end of the day. After partly cloudy skies tonight, the mid-week looks to be dry and chilly in the DC metro region and then there can be a touch of rain on Thursday, Christmas Day, from another “clipper” system that moves from northwest-to-southeast. A more impactful low pressure is likely here at the end of the week with ice on the table as strong high pressure positioned to our north acts as a source of cold air for the northeastern states.

It stays quite mild around here right through the week with temperatures soaring to well above normal levels of late December. In fact, Christmas Day (Thursday) is likely to feature afternoon temperatures peaking in the low-to-mid 70’s and there will likely be plenty of sunshine to go along with the unusual warmth.

Low pressure to our north will produce accumulating snow in the area early today and then a mixed bag of precipitation is likely before it all winds down around mid-day…watch for slick spots through the morning, accumulations of a coating to an inch or so. After clearing skies tonight, the mid-week looks to be dry and chilly in the Philly metro region and then there can be a touch of light precipitation on Thursday, Christmas Day, from another “clipper” system that moves from northwest-to-southeast. A more impactful low pressure is likely here at the end of the week with significant ice or accumulating snow on the table as strong high pressure positioned to our north acts as a source of cold air for the northeastern states.

The big weather story around here will be the continuation of our recent warm and dry weather pattern for the next few days with afternoon highs well up in the 60’s. It does turn colder by the weekend, but temperatures will still be in the moderate zone with highs on Saturday and Sunday near the 50-degree mark.

While the nation’s mid-section enjoys rarely ever-seen sustained warmth for Christmas week, the northeastern states will experience plenty of winter weather during the next 7 days or so. One system will bring some snow and ice to the northern Mid-Atlantic region and Northeast US from late tonight into Tuesday and though not a significant event, there can be some slippery spots tomorrow even in the big cities along the I-95 corridor from Philly-to-Boston. Another storm could threaten the Mid-Atlantic region and Northeast US with accumulating snow and significant ice at the end of the week with strong high pressure positioned over eastern Canada anchoring an Arctic air mass. By the end of the upcoming weekend, another low pressure will slide to the Great Lakes, and its training cold front will head to the east coast. This combination can produce rain, ice and snow across the northeastern states late in the weekend and it’ll be followed by another Arctic air outbreak for the first part of next week.

A cold front passed through the region late Sunday and the new work week will start off on the cold side with sun giving way to increasing clouds. A “clipper” low pressure system over the Great Lakes will bring thickening clouds to the area by this evening and snow is likely late at night as its moisture field moves in from northwest-to-southeast. On Tuesday, temperatures will climb above freezing and the precipitation will become a mixed bag of rain, sleet and snow before an ultimate changeover to rain. Watch out for some slippery spots during the AM commute on Tuesday and a coating to an inch of snow is possible before any changeover takes place.

A cold front passed through the region late Sunday and the new work week will start off on the cold side with sun followed by increasing clouds A “clipper” low pressure system over the Great Lakes will bring thickening clouds to the area by this evening and there can be a bit of late night snow or a mixture of rain, sleet and snow before a changeover to all rain for the morning hours on Tuesday…little to no snow accumulation is expected. Clearing skies on Tuesday night will be followed by a dry, breezy day at mid-week.
