March has begun like a lion with cold and an active pattern and there is one more storm to deal with before an Arctic blast arrives and this storm may have the biggest impact of all. Storm #1 brought accumulating snow to much of the Mid-Atlantic region on Thursday night, storm #2 brought snow and ice to many areas on Friday night, and the next storm is likely to begin on Sunday afternoon with the most potential of all as it will be loaded with moisture. The immediate I-95 corridor region from DC-to-Philly-to-NYC is going to be the “battle zone” region with significant snow accumulations to the north and west and mainly rain to the south and east.

March has begun more like a lion than a lamb and there are two more storms to deal with over the next few days which can bring additional accumulating snow and ice to the Mid-Atlantic region. Storm #1 brought accumulating snow to the Mid-Atlantic region in the overnight hours and is now pushing off the coastline, but there will be no clearing behind it. In fact, storm #2 is already gathering strength in the Southeast US and its precipitation shield will expand noticeably later today as it gets invigorated by an upper-level wave of energy. This next storm can start as a wintry mix tonight and a transition to all snow is possible in the overnight hours; especially, to the north and west of I-95.
Storm #3 arrives on Sunday afternoon and has the greatest potential of all for a significant impact as it will be loaded with moisture. The immediate I-95 corridor region from DC-to-Philly-to-NYC is liable to be the “battle zone” region with significant snow accumulations possible to the north and west and mainly rain to the south and east. There is the potential for 6+ inches of snow to the north and west of Philly and NYC and perhaps even as far south as the far northern and western suburbs of DC - but some details still have to be ironed out. All of this activity will be followed by an Arctic outbreak for next week across much of the nation.

March is coming in like a lion with overnight accumulating snow and two more storms are on the way. Low pressure is now heading towards the Mid-Atlantic coastline and it is bringing us round one of an extended precipitation event. That same low pressure system will hang around the Mid-Atlantic coastline during the remainder of today and it’ll get energized by early tonight as upper-level energy passes overhead. As a result, after a break for awhile in the precipitation, more rain, sleet and/or snow can fall early tonight and then likely transition to all snow late with additional accumulations of a couple inches possible. Yet another wintry precipitation event is headed to the NYC metro region for later Sunday into early Monday. This next system will have plenty of available moisture; consequently, a lot of potential, but it is unclear as to where the all-important rain/snow line may set up. Rain, sleet and/or snow can break out in the Mid-Atlantic region during the afternoon hours on Sunday and then possibly transition to all snow Sunday night with snow accumulations possible to the north and west of the metro area...stay tuned. All of this will be followed by Arctic cold for the first full week of March.

March is going to begin with some accumulating snow for the Mid-Atlantic region and it could have an impact on the Friday morning commute in the DC, Philly metro regions. Low pressure will push towards the Mid-Atlantic coastline in the overnight hours and snow is likely to break out around or shortly after midnight in the DC-to-Philly corridor and it can be mixed with sleet and/or freezing rain at times; especially, south of the PA/MD border. That low pressure system hangs around the Mid-Atlantic coastline on Friday and gets energized late in the day as upper-level energy passes overhead and this can lead to more rain, sleet and/or snow from late Friday into early Saturday including additional accumulations in some areas. Yet another wintry precipitation event is likely headed to the Mid-Atlantic region for later Sunday into early Monday. The late weekend system will have plenty of available moisture to it; consequently, lots of potential, but it is unclear as to where the all-important rain/snow line may set up.

March looks like it will get underway with some snow in the NYC metro region as an active weather pattern continues across the nation. Low pressure will pull out of the Midwest later today and slide across our area late tonight and likely bring snow that can be mixed with sleet and/or freezing rain at times. Average accumulations of a coating to an inch or two are on the table by mid-day Friday with the higher amounts on the southwest side of the metro area. It stays unsettled later tomorrow, tomorrow night and Saturday with another couple of waves possibly generating some chilly rain for the area and snow or sleet can be mixed in at times. A cold front slides towards the Mid-Atlantic region on Sunday and this could set the stage for an important late weekend wintry event, but it is too early to say if it will feature rain, sleet or snow or some combination of the three.

March may come in like a lion…a cold lion…as about 2/3rds of the nation will be well below normal for early March with the cold wave extending from the Rockies to the New England coastline and to the Gulf coast. In addition, the calendar turn from February to March will be accompanied by an active weather pattern with multiple waves of energy and an accumulating snow threat in the I-95 corridor late tomorrow night/early Friday and another wintry event possible late in the weekend.

Winter is not going to give up without a fight despite what the groundhog predicted a few weeks ago. The calendar turns from February to March this Friday and the new month will begin with an active pattern to include additional cold air outbreaks and some snow threats. The first threat of snow will actually take place later today and tonight as a “clipper-like” system drops southeastward across the Great Lakes. Snow showers could reach into the metro region later today and continue tonight as this system passes by to our north, perhaps resulting in minor accumulations. Another system could generate some snow or rain here on Friday – just as we begin the month of March. A cold air outbreak is likely to arrive in the Mid-Atlantic region on Sunday and low pressure may form near the Southeast US coastline right along the cold frontal boundary zone. This could result in another wintry precipitation event from late Sunday into Monday with the chance of snow or a wintry mix. The first full week of March will be well below-normal in much of the nation including the Mid-Atlantic region.

Winter is not going to give up without a fight despite what the groundhog predicted a few weeks ago. The calendar turns from February to March this Friday and the new month will begin with an active pattern to include additional cold air outbreaks and some snow threats during the next week to ten days. The first threat of snow will take place tomorrow night in the northern part of the Mid-Atlantic region as a “clipper-like” system drops southeastward across the Great Lakes. Another relatively weak system could generate some snow in the DC-to-Philly corridor late Thursday night/early Friday – just as we begin the month of March. A cold air outbreak is likely to arrive in the Mid-Atlantic region on Sunday and low pressure may form near the Southeast US coastline right along the cold frontal boundary zone. This could very well turn into the most important threat of all for snow in the Mid-Atlantic region as signs point to a northward push of moisture along the east coast late Sunday into Monday with fresh, cold air in place. Finally, as a vigorous wave of upper-level energy drops into the Great Lakes region early next week, the another system could develop near the east coast, but it is certainly too early to say if that will come close enough to the Mid-Atlantic to produce snow.

An active weather pattern is in store for the Mid-Atlantic region for the next week or so. High pressure will edge into the region today and this will cause a relaxation in the pressure gradient and noticeably less wind compared to Monday. A fast moving low pressure system will cross the Ohio Valley late tonight and early Wednesday and spread clouds into the Mid-Atlantic region and snow showers are possible here late tomorrow and tomorrow night - perhaps even a period of steadier snow with small accumulations. Another disturbance will head our way by early Friday and this system can bring us some snow as we end the work week. Looking ahead to the weekend, it’ll turn a bit milder on Saturday with a chance of rain and then colder on Sunday and we'll have to watch moisture to our south that may try to push northward along the east coast as we end the weekend. Yet another system may try to ride up along the east coast by the middle of next week.

A powerful storm over southeastern Canada is combining with strong high pressure over the Upper Midwest to create a very tight pressure gradient field today and this is leading to high winds gusts across the Mid-Atlantic region. Winds can gust into the 50-60 mph range and scattered power outages are possible given the well saturated grounds which can weaken root systems of trees. The air mass is quite chilly as we begin the new work week and it’ll feel much colder with the strong winds. After a calmer and sunny day on Tuesday, a couple of disturbances have to be watched for the mid-to-late week as they can throw some snow or rain our way.
