Some of the moisture from the coastal storm will be "thrown" back our way and interact with the cold front moving through causing some light snow during Monday night. Amounts of 2-4 inches will occur East of the Hudson river valley through Western New England. Overnight amounts elsewhere will be 1-2 inches by morning.
During Tuesday we'll focus our attention on a Clipper system moving southeast across the Great lakes. This low is expected to weaken BUT transfer its energy to a new low off the Delmarva coast by late Tuesday. This coastal low is then forecast to track east to east northeast far to our south, so once again no significant snow fall is expected. However with the weakening clipper sliding across the area on Tuesday once again we could see some occasional very light snow or snow showers and once again temperatures will be in the 30s.
By Wednesday the second coastal low will be turning northeast and merge with the first coastal storm making for an intense low pressure area near the Canadian Maritimes. This will result in strong N-NW winds developing over us and colder air moving in. Highs Wednesday will be in the low 30s, with some 20s north of Albany. Once again a few snow showers are possible but nothing significant in terms accumulations.
Thursday will be a windy cold day with the threat for a snow shower or two. Its during Friday that the arctic air will arrive, thanks to an arctic cold front will pass through the region accompanied by afternoon snow showers and perhaps some snow squalls. Look for temperatures to quickly plunge by Friday evening and night into the single numbers along with very low wind chill values of at least -10°, if not lower.
Saturday will be downright cold. High temperatures will only be in the single numbers to low teens and once again with strong winds, expect very low, perhaps dangerously low, wind chills, too.
