Models are now starting to come into a semblance of agreement in regards to where New England’s Tuesday storm will track. In a completely expected turn, after pushing the storm well south of New England, most guidance has begun to edge the storm further north. At this time, it is looking increasingly likely that the storm will pass New England near the benchmark. This increases chances for an impactful snowstorm for much of southern and central New England.
The overall setup for the storm will involve a primary low tracking up the Appalachian Mountains and into the Mid-Atlantic early Tuesday morning. As it does so, a secondary low will form off the Mid-Atlantic coast and strengthen as the primary low weakens. This all supports a colder storm with mostly snow falling across New England.
The biggest issue for snowfall will be the lack of cold air ahead of the storm. Record high temperatures are possible on Saturday with Sunday and Monday only a notch cooler. Colder air will be filtering into New England on Tuesday as a cold front drops south. Also, models are showing a deep low pressure system, with the central pressure dropping to around the 980mb range.
