The National Weather Service has issued a fresh round of Winter Weather Advisories and Winter Storm Warnings ahead of the next weather system expected to impact portions of the Mid Atlantic for the balance of the work week. This next storm is part of a parade of storms that continue to march across the region.
It appears the disturbance that’ll bring wintry weather to the Mid Atlantic will move somewhat more north than initially thought yesterday. Because of that, light snow is now expected to fall as far north as northern New Jersey, with snow flurries or a dusting of snow even possible now in New York City. However, this shift north is also bringing somewhat milder air, which will introduce more plain rain, sleet, and freezing rain on the south side of the system.
Because of these tweaks in the forecast, the National Weather Service has expanded Winter Weather Advisories further north into central Pennsylvania and New Jersey. With the possibility of snow and ice, Winter Storm Watches are now up for much of Virginia. Winter Storm Warnings are now up for portions of West Virginia and Kentucky where there could be dangerous ice accumulations from freezing rain.
A parade of winter storms continues to march through the eastern United States. After one system brought light precipitation to portions of the northern Mid Atlantic and southern New England yesterday, it appears system #2 will approach from the west starting late tomorrow, with snow lingering over portions of the central and southern Mid Atlantic through Friday. It looks like #3 will arrive in time for the weekend, with two more in the extended forecast for next week.
A frontal zone will set-up across portions of the Mid Atlantic, setting the foundation for an area that snow will fall over the next several days. Two distinct waves of low pressure will move through this zone, creating two opportunities of snowfall within the unsettled Wednesday-Friday period. While some areas could see snow throughout the entire three day period, those on the northern side of the system may only see some snow late Wednesday/early Thursday and once again late Thursday/early Friday. And unlike past storms that pushed precipitation north into New England, high pressure over the northeast will keep the precipitation over the Mid Atlantic rather than New England.
When all is said and done, 6-10″ of snow is probable across portions of western Virginia and Maryland and eastern West Virginia. The Washington, DC and Baltimore, MD metro areas will see less snow; at this time, it appears Washington, DC will see on the order of 2-4″ while Baltimore could see 3-5″. North of there, into southeastern Pennsylvania and south-central New Jersey, even less will fall with 1-3″ expected in places like Philadelphia and surrounding suburbs. In Delaware, up to 6″ may fall in portions of the state; however, with mixed precipitation, only an inch or two is now expected in southern portions of the state. Light snow is also possible in northeastern Kentucky, most of central Virginia, and north-central North Carolina from this system.
The third system in this parade of winter storms is expected to impact the eastern United States this weekend. However, with precipitation amounts and types dependent on a too-soon-to-know storm track, it is too early to produce a snowfall forecast map for that system at this time. It appears storms next week could be just as impactful too in this very active weather pattern.
