DAYS 1-5 (FEBRUARY 11-15)
Low pressure passes south of the region today bringing its steadiest rain south of I-90, but low level moisture has a lot of area north of I-90 foggy and drizzly to start the day, and low level cold in the Merrimack Valley, northeastern MA, and southern NH has a few areas sitting just below freezing, so some icy areas will be out there to start the day before it warms up and that condition dissipates. Use caution if traveling in those areas early today. High pressure brings a chilly, dry interlude Wednesday. The next low comes along with a little colder air to work with and should start as snow/mix for most areas pre-dawn Thursday, but as has often been the case in the long-term pattern we’ve been in, there isn’t anything to hold the cold in and we will warm up enough for a flip to rain across the region, quickly to the south, eventually to the north. And then we get something we haven’t seen that much of this winter, really cold weather, to end this week.
