Yet another chance for snow is in the cards, this time ahead of a warm front as a weak storm forms over southeastern Canada aided by an upper-level disturbance swinging through. With cold air in place, that combination of cold and moisture will lead to snow.
Leading up to this snow will be temperatures early-Friday morning into the 20s for most locations where snow is expected. That will set the stage for accumulating snow. Most areas will experience a light snow, so main roads should be clear and just wet and slushy, but the secondary roads may become slick, especially if a moderate snow moves in with snowfall rates near 1 inch per hour. Based on the latest timing, snow is expected to fall early Friday morning before sunrise from Lake Erie through eastern Pennsylvania and possibly even New Jersey. Temperatures will be a bit warmer in the I-95 corridor south of New York City, however, so accumulation — if any — will be confined to the cold and grassy surfaces. Then around sunrise through the late-morning, snow is currently forecast to move into most of New York State, including Long Island, and southern and central New England. These areas have the best chance for accumulating snow, especially if it falls at a heavier snow rate. If is comes down as a light snow, then there won’t be much accumulation due to the strong April sun. Then in the afternoon on Friday, the snow will clear out of much of the region. The areas that will still be impacted in the afternoon will be northern New England, Maine, and Upstate New York. Also on the backside of this precipitation, especially the further south you are, the snow may actually end as rain for a brief time.
Then overnight, a cold front will attempt to reach the coast but will stall out while cold air surges in from the north and west. Therefore, additional snow is expected across most of the Northeast Friday night as a new storm moves into the Mid-Atlantic.
Again, accumulation will be light. Due to the complicated forecast with the storm over the Mid-Atlantic, our snowfall forecast below only includes the snow Thursday night into Friday.
