A light to moderate interior snow event is likely in Southern New England late Tuesday evening through Wednesday morning. A system riding along a stalled front south of Southern New England will bring snow and rain starting late-Tuesday evening. There will be colder air in place, but the storm may track just close enough to SNE to allow for rain or a mix from the coast to Providence for part of the event. Farther inland, there is a better chance of snow.
Right now, it looks like a borderline plowable snow NW of I-295 in RI and W of I-495 in MA, as well as most of interior CT if the storm tracks close to the coast. If the storm tracks a bit farther offshore, a more widespread 1-3″ snowfall is likely, as colder air hangs on near the coast. The best chance of 3-4″ inland is with the track near the coast. Of course, in that scenario, it’s the best chance of 0-1″ near the coast to Providence because of the milder air. The best chance of the high-end totals near the coast is if the storm is farther south, and that also leaves less snow in interior sections because they will be right on the fringe of the steady precipitation.
We will continue to update and tweak this map as necessary.
The “height” of this minor-moderate event may coincide with the Wednesday AM commute. If it takes the track closer to the coast, the only threat of icy roads is in the areas shaded in yellow.
