An elongated area of low pressure will send periods of heavy rain with embedded thunderstorms through tonight, a cold front will approach from the northwest and allow for colder air to move into the region. Ski country looks to get 4-8 inches of snow with 0-4 in the valleys. There will likely be areas of central and Northern New England that experience up to a half inch of ice. In the Merrimack Valley expect temperatures to drop tomorrow morning. Highs will occur pre-dawn hours with highs in the 50s but will drop rapidly and be in the 20s by late morning and afternoon. The heaviest of precipitation should be ending for the lower sections of the valley in Northeast Massachusetts by the time this change from pure rain to freezing rain/sleet occurs. Looking ahead, temperatures look to remain in the 20s for the second half of the holiday weekend through the week. We will have to monitor a chance of some snow showers Tuesday night into Wednesday as a quick moving clipper moves in from the northwest OR the energy involved with this clipper could interact with a piece of energy further south and give the region a good snowstorm Mid to late week but all the players need to be looked. There will be a better understanding of this come Monday.
