** SHORT TERM UPDATE **
A low pressure wave in the Gulf of Maine has shoved the warm front back to the south as a back-door cold front that has now chilled down southern NH and most of eastern MA. Temperatures have fallen from the lower 40s to the lower 30s and with some fog forming, there may be some patchy ice forming on untreated surfaces overnight. Be aware of this if you are heading outside tomorrow morning as it probably will remain chilly into mid morning.
A slight tweak to the forecast appears in the TONIGHT section below, otherwise, the remainder is unchanged from the original post.
The lack of significant winter storms will continue, in fact there is very little risk of important storminess for the foreseeable future (that is, 7 days, possibly longer). Temperatures will continue to ride a little bit of a roller coaster, though this will not be extreme either. Brief cold shots come between near to above normal temperature stretches, with the midwinter chill being a bit more dominant in the days ahead.
A warm front passed by early Tuesday. Snowfall was less than expected, with most occurring across NH and Maine. A cold front will pass by on Wednesday, but with very mild air in place expect a risk of rain showers in a short window of time just ahead of the front. Generally dry weather is expected Thursday through the weekend as a sprawling area of high pressure builds across eastern Canada and the northeastern US. Low pressure will pass well south of the region Thursday with no impact.
