It goes without saying that this winter has been very frustrating for snow lovers in the DC-to-Philly-to-NYC corridor as there just hasn’t been the right combination of cold and moisture to result in significant snowfall. A strong cold frontal passage at mid-week will indeed usher in a cold air mass fully capable of producing snow in the Mid-Atlantic region as long as moisture becomes available. In fact, there will be plenty of moisture meandering across the southern US over the next couple of days and it looks like some of this will northeastward into the Carolinas and as far north as southern Virginia at the same time this upcoming cold air mass becomes firmly established. The result may be a significant snow event from southern Virginia to upstate South Carolina with half a foot possible in North Carolina and – as has been the case for much of the winter – snow lovers from DC-to-Philly-to-NYC will be looking with envy from the outside. Longer term, there are some signs of hope for cold and snow in the Mid-Atlantic’s I-95 corridor, but we have had false promises already this winter and time is beginning to run short.

High pressure will push off to the north and east today and a cold front will approach the area from the northwest. This front will generate occasional showers in the Mid-Atlantic from this afternoon into the evening, but it doesn’t look like a significant precipitation event. High pressure builds in behind the front on Wednesday and it’ll turn slightly colder and then we’ll turn even colder on Thursday and Friday with highs confined to the upper 30’s on both days. There will be a lot of moisture to watch later this week across the Southeast US, but for now, it looks like it’ll stay just to our southeast potentially causing some accumulating snow in the Carolinas and southeastern Virginia.

High pressure will control the weather around here as we start the week, but a strong cold front will approach from the northwest on Tuesday. As a result, we’ll start off dry and chilly today, but rain showers are likely on Tuesday as the front closes in on the eastern seaboard. Following the front, another cold air mass will arrive in the Mid-Atlantic and it is likely to stay cold and dry through the end of the week.

Arctic air has pushed into the Mid-Atlantic region and temperatures today will do no better than the middle 30’s for highs and temperatures will plunge to bitter cold levels by early tomorrow in the mid-to-upper teens. Winds will be noticeable today out of the northwest making it feel even worse that the actual air temperatures. High temperatures on Saturday will again be confined to the 30’s - well below-normal for this time of year where the normal high in DC is 45 degrees. Strong high pressure will then push off the east coast late Saturday and temperatures will ease on Sunday with highs back to near 50 degrees and well into the 50’s early next week. One final note, the rocket launch that was originally scheduled for late Sunday afternoon at NASA’s Wallops Island Facility has been rescheduled for this afternoon at 3:43 PM and it may be visible throughout the Mid-Atlantic region. The original launch was scrubbed due to a faulty sensor issue which should be resolved by week’s end. Weather can be an issue as winds will be quite gusty out of the northwest throughout the Mid-Atlantic region.

An Arctic front has pushed through the Northern Plains and into the Upper Midwest at mid-day and temperatures have plunged to below zero in many locations. In addition, winds are quite strong in these same areas resulting in dangerous wind chill values as low as 30 degrees below zero. This Arctic air outbreak will continue to push to the south and east over the next 24 hours and will bring some of the coldest readings yet this season to the Mid-Atlantic and Northeast US by the early part of the weekend. As has been the case for much of the winter, the cold air will be rather short-lived and temperatures will ease noticeably by Sunday afternoon in the Mid-Atlantic/NE US.

Low pressure will pull away later today and head towards the waters off of eastern New England. The low pressure will drag a cold front through the region later in the day and an impressive cold air outbreak will arrive in the overnight hours and it'll stay quite cold into the weekend. Temperatures both tomorrow and Saturday afternoon are likely to be held in the middle 30's for highs and it'll be bitter cold tomorrow night with lows in the mid-to-upper teens - some of the coldest readings so far this season. One final note, the rocket launch that was originally scheduled for late Sunday afternoon at NASA’s Wallops Island Facility has been rescheduled for Friday, February 14th at 3:43 PM and it may be visible throughout the Mid-Atlantic region. The original launch was scrubbed due to a faulty sensor issue which should be resolved by week’s end. Weather can be an issue on Friday as winds will be quite gusty out of the northwest throughout the Mid-Atlantic region.

There will be a break today in the recent active weather pattern as high pressure takes control for a short period of time. Another low pressure system, however, will move in this direction from the Tennessee Valley and impact us with more rainfall from late today into Thursday afternoon. Following this next system, an impressive cold air outbreak will arrive on Thursday night and it'll stay quite cold into the first part of the upcoming weekend. Temperatures on Friday and Saturday will struggle to reach the mid or upper 30’s for afternoon highs and there will be a stiff NW wind at times to make it feel even worse.

A wave of low pressure will track along a frontal boundary zone today from southwest-to-northeast and produce more rainfall in the Mid-Atlantic region. There will be a brief break in this active and unsettled weather pattern from tonight into late Wednesday as high pressure takes over for a short period of time. Another low pressure system, however, will then impact us with more rainfall from late Wednesday into Thursday. Quite an impressive cold air outbreak will arrive here on Thursday night and temperatures will struggle to reach the middle 30’s on Friday and there will be strong winds from the northwest. One final note, the rocket launch scheduled for late Sunday afternoon at Wallops Island, VA was scrubbed due to a faulty sensor. The next attempt will be no earlier than Thursday afternoon.

Low pressure will track to our north today and drag a cold front through the region and then another low pressure system will ride up and along the frontal boundary zone on Tuesday. As a result, the week will start on an unsettled note with occasional rain today, tonight and Tuesday. High pressure will arrive at mid-week and then we’ll have to watch for yet another system as it pulls out of the southwest and heads in this direction likely with more rainfall on Thursday. An impressive cold air outbreak will arrive here on Friday and it'll stay quite cold to begin the upcoming weekend.

Strong low pressure will move over the interior part of Pennsylvania today on its way to eastern New England and a strong cold front will sweep eastward through the region. This frontal passage will be accompanied by more rain and winds can gust to 50 mph. In addition, there can be a strong-to-severe thunderstorm this morning containing heavy downpours, damaging wind gusts and perhaps even small hail. High pressure takes over to start the weekend, but a weak system could produce some snow showers on Saturday night.
