Temperatures plummet tonight as skies become partly cloudy. A passing flurry is possible but overall the trend is for dry weather into the beginning of the work week. Any snow and ice not removed today will be rock solid hard overnight and Monday morning as the cold air stays in place for a good portion of this week.
High pressure pays a visit Monday as temperatures remain frigid through the day despite a good amount of sunshine. Brisk winds will make it feel even colder than the actual temperatures as mid Winter conditions prevail and we remain much below normal in the temperature department. Combining the wind with the cold temperatures will bring us wind chills in the area of 5 to 10 degrees during the day. Another bitterly cold night follows before we turn our attention to another winter weather maker for Tuesday.
Low pressure will move offshore to our south and should be positioned near Long Island Tuesday night. The low intensifies as it tracks northeastward toward the Maritimes on Wednesday. There remains some question as to how much intensification this system will undergo and more importantly when it occurs. This could turn out to be a light snow event here but with higher impacts throughout eastern Massachusetts. Timing is everything as they say and that holds true for developing weather systems. If this system intensifies early we could see more than just light snow.
Plan on a good chance for periods of light snow Tuesday, coming to an end Tuesday night. One thing that remains certain is that the very cold air will continue to be with us. Too early to nail down any accumulations, but an early guess would be one to three inches. This can change.
Conditions improve Wednesday as the developing storm takes shape and moves into eastern Canada. We may actually see a milder trend toward the end of the week before more sloppy weather appears by next weekend.
