Several wintry storms in the East – Monday through Saturday will be an interesting period in the East as three separate disturbances bring wintry precipitation to the East. Friday could bring the biggest risk of snow to the Mid-Atlantic, with significant snow possible in southern New England.
A quiet weekend ahead? – After the coastal storm moves out of the U.S. on Friday, a quiet weekend could be in store for most of the U.S. aside from some lake-effect snow and a weak disturbance in the West.
Deep cold moving into the Northeast – The coldest temperatures of the season are expected to move into the Northeast this weekend and into early next week as lows drop into the negatives.
The complicated weather pattern continues this week in the East as three disturbances move through the region. The first one will move up the East Coast tonight and through Tuesday, bringing some snow, mixed precipitation and rain to most of the coast. Interior areas are expected to see the worst of it as temperatures stay cool enough for snow and mixed precipitation to stick, while areas closer to the coast should change over to rain for a significant portion of the event. Needless to say, travel will be a mess at the onset of the storm, and the precipitation will become a concern again behind the system as what does end up on the ground freezes over.
Shortly behind this system, a shortwave will bring a weak but potentially hazardous shot of wintry weather into the Mid-Atlantic on Wednesday, with an inch of snow (or 0.1″ of freezing rain or sleet) possible in the region. The Southeast could see some light rain from this disturbance.
The Plains will see a shot of wintry weather on Wednesday as a third disturbance ramps up over the mid-country. the Central Plains and Midwest will get a shot of wintry precip. as the storm progresses eastward. Depending on the storm’s track, which is still variable and up to a lot of debate, this system could bring snow and mixed precip. to the Mid-Atlantic and Northeast late this work week, with significant snowfall on the order of 6-12″ possible in some areas further north. The areas most likely to see these kinds of totals is the western Appalachians in the Mid-Atlantic and in southern New England (as if they didn’t have enough snow already this season!).
Going into the weekend, a calmer weather pattern is in place as no significant storms show up over the U.S. However, in place of dynamic weather we instead of widespread cold, with belows over almost all of the eastern half of the country. The biggest effects of this cold will be seen in the Northeast, where many areas will see their coldest temperatures of the season over the weekend and into early next week. The blocking pattern over the Atlantic has kept the Northeast relatively mild so far this winter, so the cold temperatures will be a bit of a shock to the system as lows (and in some areas highs!) drop to below zero Fahrenheit.
