Boston metro north covers the North Shore, Merrimack Valley and Northwest Suburbs:
Above normal temperatures continue into this weekend, with high temperatures reaching into the 40’s through Saturday. As we progress with this unusually mild winter season lets take a brief look at February. The first half of the month we have experienced above normal temperatures on 11 days, below normal readings for 3 days and 1 day with normal readings. At Logan International Airport the mercury is running about 4.5 degrees above seasonal averages for the first half of February. Not only are we lacking in snowfall but overall it continues to be dry as well, with very little precipitation this month. February precipitation has only been 0.07 inches which stands 1.59 inches below normal so far this month.
One low pressure system moves out of the Ohio Valley into Canada, with a second low developing well south of New England. With the mild temperatures expected to continue the remainder of the week it is likely northeastern Massachusetts has rain from this system, with a chance of a wintry mix well inland late Thursday night and early Friday morning. If any snow does mix in with the rain it is expected to be in the Northwest Suburbs and Merrimack Valley. From Thursday night through mid-day Friday is the best chance for periods of precipitation. There is no expectation of any snow accumulation. As the low in Canada moves further away from New England the associated front will push through by Friday afternoon, with improving weather that will last into the overnight. The air mass behind the front will deliver more above normal temperatures as there is no cold air behind this system.
Saturday brings fair weather as sunshine returns. Temperatures remain above normal, with highs into the 40’s again to start the weekend. Nighttime readings falling to near seasonal averages.
On Sunday it will cool a bit to seasonal levels and there is some question if a low pressure system moves up the coast or goes harmlessly out to sea. Still much uncertainty on the track of this storm but there is some suggestion this storm, like so many others this season, will track too far south of New England to give us a major storm. There remains the possibility of a glancing blow over southeastern New England. For now we are calling for a mostly cloudy Sunday in northeastern Massachusetts, with any precipitation from this storm system sliding south of the area. That can change of course, but that is the way we see it at this time.
