A bit of an unorthodox set up with this one. A very strong storm will move almost due north over the Great Lakes, giving parts of the mid west blizzard conditions. Normally, a storm tracking so far to our north and west would result in a warm wind direction at the surface, causing any associated precipitation to fall as rain.
While I don't expect an all snow event (for Boston), we finally have the benefit of some solidly locked in cold air which allow everyone to start out as snow on Wednesday night.
8pm on Wednesday night looks to be the peak time for snowfall for Eastern Mass. It could be heavy at times during the 4-6 hours that follow, especially in higher elevations. Early totals could be anywhere from 2-4 in Boston and in points southward with 3-6 in areas north and west of the city.
Once this initial burst moves through, a warm front will pass through our region, likely changing any leftover precipitation to rain.
This forecast is highly uncertain however, due to the complex set up. A second system appears to move over Northern New England on Thursday night, giving areas up there a decent snowfall. As of now, it looks like the only meaningful snowfall Boston will get is from the first wave on Wednesday night.
More updates as we get closer to Wednesday
Hope you nail this one.
