Following record heat midweek and snow for some on Thursday, more rounds of snow and ice can be expected across portions of the interior Northeast this weekend as two more disturbances move in.
On Friday, we’re going to see precipitation move in from west to east as the day progresses. As warm in moves in aloft, there will still be some freezing cold air stuck at the surface, so freezing rain is possible in the Catskills, the Adirondacks, the Lower Hudson River Valley, the Berkshires, and the Green and White Mountains. There will be a thinner layer of that warm air aloft in northern New England, so both freezing rain and sleet is possible in the higher elevations; in the valleys, it will be a cold rain. A cold rain will be the story for the remainder of the Northeast with periods of rain forecast for many major cities, including: Buffalo, New York, and Boston. In the evening, it may turn a bit hairy in the Portland area with rain transitioning to a wintry mix of freezing rain and/or sleet. For northern and inland Maine, this will mainly be a snow event during the afternoon and evening. All of the precipitation from this first disturbance should clear out by midnight, and temperatures will rise to the mid 30s for many locations that experienced freezing rain so some melting is possible.
Our next storm will begin to move in on Saturday and will continue through Sunday. In the morning of Saturday, a batch of line rain showers will move in from the west, affecting areas near the Pennsylvania/New York line into the New York City area. Then into the afternoon, the rain showers will become a bit more widespread in activity, affecting similar areas as well as into the northern Mid-Atlantic region, including Washington, D.C. and Philadelphia. Now as we get into Saturday night, the actual storm will begin to move in, bringing a widespread rain to the northern Mid-Atlantic, most of the interior Northeast, and southern New England. In the Adirondacks, northeastern Catskills, Berkshires, and northern New England, however, wintry weather will strike again. This is where freezing rain, sleet, and snow will fall from early-Sunday morning through as late as Sunday night. This will be an inland event with the greatest impacts in the higher elevations of northern New England. The valleys for the most part should remain warm enough for a mainly rain event. Also at the coast of Maine, it may begin as snow briefly, but will changeover to rain by the afternoon, with the exception of down-east Maine.
Localized areas in the Green and White Mountains may receive over half a foot of snow, but this will be a minor event for most areas. Take the freezing rain seriously, however, because just a glaze of ice can make travel very dangerous.
