Snow makes a return and so does the cold weather

An innocent looking storm system across will quickly spread its moisture into Vermont Monday. This is a weather system that caused thunderstorms with sleet across the Great Lakes in spite of the fact that the storm only has a central pressure of 1010 mb. It is the clashing of airmasses that is acting as the ignition for the intense area of precipitation and as this area of precipitation moves east into the colder temperatures it will snow. The snow will fall mainly across the northern part of the state beginning during the midday hours Monday and persisting through Monday night. The 8-12 inches wiy ll be a nice little victory this late in the season as the snow will turn heavy for a time late Monday. At the base the snow will be of a wetter consistency but the upper half of the mountain should see powder. The snow will taper to flurries by Tuesday morning and sunshine will make a return.

We talked about another storm during the midweek period, another product of a major clash in airmasses. Like before it looks like most of the snow will travel to our south although a few recent runs of the GFS American Model have the region getting grazed with a few inches. We do now it will be very cold for late March with temperatures remaining below freezing for the most part through the end of the week. The cold weather may abate somewhat by the weekend but temperatures will remain below normal and we may get just enough instability for occasional snow showers.
