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.

As one powerful storm exits towards southeastern Canada, another system is gathering strength over the western US and it will become a powerhouse by Friday evening over the Upper Midwest/Great Lakes. This next strong storm will generate blizzard conditions over much of the Midwest and Great Lakes region from later Friday into Saturday and it’ll produce more heavy rain and strong winds for the Mid-Atlantic and Northeast US. Meanwhile, there has been a buildup of intense cold air over western Canada in recent days and it is now slipping south and east and into the US. This late week/weekend major storm system will actually help in its advance to the south and east and much colder air will work its way all the way to the eastern seaboard by the second half of the weekend. As it turns out, there are signs that a storm may intensify early next week somewhere near the east coast and with the expected late weekend influx of much colder air, accumulating snow may be on the table this time for the big cities along the I-95 corridor.

The powerful storm system that brought heavy rainfall and howling winds to the region yesterday and last night will push into southeastern Canada today. Winds will remain quite strong gusting up to 40 mph or so, but from a westerly direction on the back side of the departing storm system. Another powerful storm system can bring heavy rain and strong winds to the Mid-Atlantic region on Friday night and this second system will usher in much colder air for the latter part of the upcoming weekend and the early part of next week. In fact, there will be some intense cold this weekend dropping southward from Canada into the US and some of this Arctic air will trek south and east reaching the eastern seaboard later in the weekend. A third storm system threatens the eastern states early-to-middle part of next week and this time snow will be on the table in the I-95 corridor given the expected preceding arrival of Arctic air.

A powerful storm system will bring heavy rainfall and increasingly strong winds to the Mid-Atlantic region and Northeast US this afternoon and tonight leading to localized flooding and unfortunately, numerous power outages are on the table. The grounds are well-saturated from recent heavy rain events and today’s storm can add another 2 or 3 inches with isolated higher amounts possible. Winds can gust to 55 or 60 mph along the interior sections of the I-95 corridor with even higher amounts along coastal sections of the Mid-Atlantic and Northeast US. As a result, trees, limbs and power lines will be quite vulnerable leading to the fear that power outages can become widespread.
Another powerful storm system can bring heavy rain and strong winds to the Mid-Atlantic region and Northeast US on Friday night and this second system will usher in much colder air for the latter part of the weekend and early part of next week. In fact, there will be some intense cold this weekend dropping southward from Canada into the US and some of this air will trek south and east reaching the eastern seaboard later in the weekend. A third storm system threatens the eastern states early-to-mid next week and this time snow will be on the table in the I-95 corridor given the expected preceding influx of Arctic air.

A powerful storm system will bring heavy rain to the DC metro region from mid-day through much of tonight and significant flooding is on the table. Some spots can receive as much as 2-3 inches of rain and this will be on top of already well-saturated grounds from multiple heavy rain events in recent weeks. In addition to the heavy rainfall, winds will become increasingly strong with potentially damaging gusts to 50 mph or so raising the possibility of broken limbs, downed trees and numerous power outages. Another significant storm system can produce similar conditions around here from late Friday into early Saturday (i.e., heavy rain and strong winds). A third storm system threatens the Mid-Atlantic region during the first half of next week and this time snow will be on the table.
