Another round of accumulating snow is headed to the DC metro region on Friday as low pressure intensifies just off the Carolina coastline. The snow should arrive between 2 and 6 AM and snowfall estimates are 1-3 inches across the area. On the heels of the late week snow event, another Arctic air mass will plunge into the eastern states from Canada and lows in the teens will be quite likely again this weekend in most suburban locations. Looking ahead, the Arctic chill will fade away around here early next week and we’ll turn warmer-than-normal for the middle and latter parts of next week with rain likely back in the forecast.

Accumulating snow fell in the Mid-Atlantic region from Monday into Tuesday and a second such event is headed this way for the end of the work week. Snow should develop early in the day on Friday in the DC-to-Philly-to-NYC corridor as low pressure starts to intensify just off the Carolina coastline aided by vigorous support in the upper part of the atmosphere. On the heels of the late week snow event, another Arctic air mass will plunge into the eastern US from Canada and single digits lows will be possible this weekend in some suburban locations. Looking ahead, the Arctic chill will dissipate around here early next week and we’ll turn warmer-than-normal for the middle and latter parts of next week with rain likely back in the forecast.

Very cold air has poured into the region on the heels of yesterday’s snow and temperatures today will be hard-pressed to climb past the mid-to-upper 20’s for afternoon highs and stiff winds will make it feel even colder than the actual air temperature. Another coastal low pressure system is likely to bring us accumulating snow on Friday and cold high pressure will follow for the weekend anchoring another Arctic air mass.

There can be a bit of freezing rain and/or snow this morning with little, if any, in the way of additional accumulations. Low pressure pushes off to our northeast and very cold air will flow into the area on its backside. Temperatures later tonight could drop to the teens with the influx of Arctic air and fresh snow cover. Another accumulating snow event is on tap for the end of the work week and this storm system will be followed by another Arctic blast for the upcoming weekend.

During the past couple of years, many spots along the DC-to-Philly-to-NYC corridor have not had more than an inch of snow in any single event…that “snow drought” is about to end. In fact, there will likely be two accumulating snow events this week in the Mid-Atlantic region with the first one from later today into Tuesday likely resulting in a general 2-4 inch snowfall and there can be isolated higher amounts of 5 inches. The second accumulating snow event comes at week’s end and this one has the potential to produce significant snowfall amounts. This late week system will be followed by an Arctic blast for the upcoming weekend in the Mid-Atlantic region. Temperatures are likely to climb back to above-normal levels later next week, but Arctic outbreaks are destined to return to the central and eastern US during late January and February given the on-going stratospheric warming event over the northern hemisphere polar region.

Low pressure will begin to intensify just off the Carolina coastline by later today and then push northeastward on Tuesday just off the east coast. There will be some accumulating snow around here early today (coating to an inch) and then a lull in the precipitation for the late morning hours and then the snow re-develops during the afternoon. The snow will continue tonight and into Tuesday morning with 2-4 inches likely and isolated higher amounts of 5 inches are possible…the most snowfall in many spots in a couple of years. High pressure will then take control at mid-week and then another coastal low pressure system will develop on Friday and this system has the potential to bring significant snow to the Mid-Atlantic region. Signs point to another Arctic blast to follow making for very cold conditions during the upcoming weekend with single digits lows possible in many suburban locations of the Mid-Atlantic region.

It’ll be quite an active week in the Mid-Atlantic region beginning with the arrival of an Arctic front on Sunday followed by a couple chances for accumulating snow during the work week and then there can be another Arctic blast next weekend. The arrival of the Arctic front on Sunday can come with powerful wind gusts and snow squalls that can put down a quick small accumulation anytime from late-morning to mid-afternoon. During the week, low pressure is likely to intensify just off the Carolina coastline on Monday night and Tuesday and this system will bring some accumulating snow to the I-95 corridor from later Monday into Tuesday. Another system will likely push into the Mid-Atlantic region at the end of the work week - possibly with another round of accumulating snow - and there is likely to be an impressive Arctic blast to follow for next weekend.

A powerful storm system that will produce blizzard conditions across the Midwest and Great Lakes will the Mid-Atlantic region more heavy rain and strong winds from late today into early Saturday. Given the already well saturated grounds from recent heavy rain, localized flooding is likely to become an issue with the coming rainfall and with the strong winds expected, isolated power outages are a possibility. Colder air will follow this storm for the second half of the weekend and for much of next week as well. Low pressure may intensify off the east coast in the early-to-middle part of next week and that could result in some accumulating snow for the DC-to-Philly-to-NYC corridor, but details still need to be ironed out. There is also a second threat of snow for us late next week and that one could be followed by an Arctic blast into the Mid-Atlantic region.

Arctic air is now sliding into the northern US from western Canada and this cold air outbreak will likely become big weather news in coming days as it spreads across the nation. Indeed, the Arctic air will push all the way south to the Lower Rio Grande Valley region of Texas over the next few days and much colder air will advance eastward to the east coast by the end of the upcoming weekend. Another big weather story will be the next powerful storm system that will generate a blizzard for much of the Midwest and Great Lakes region and more heavy rain and strong winds for the Mid-Atlantic/Northeast US. The large storm and intense cold will indeed play a role in NFL playoff games this weekend with Kansas City likely near 0 degrees at game time on Saturday evening and Buffalo’s game on Sunday afternoon could feature heavy lake-effect snow bands and very high winds.

Another powerful storm system can bring heavy rain and strong winds to the Mid-Atlantic region on Friday night and this next system will usher in much colder air for the second half of the upcoming weekend and it looks rather cold for much of next week as well. There are signs that a storm may intensify just off the east coast early-to-middle next week and with the expected late weekend influx of much colder air, accumulating snow may be on the table for the DC-to-Philly-to-NYC corridor. Indeed, there may be a second threat for snow in the I-95 corridor at the end of week with the possible influx of another Arctic air mass for the weekend of the 20th/21st.
