A 20-degree temperature swing means a warmer but messy Wednesday with rain and snow passing through
Emerging from the Great Lakes with a northeasterly direction, this storm is set to take a more interior track, with the core of the storm passing through Montreal instead of the New England coast.
What does this mean? Boston and most of coastal New England will remain in the warm part of the storm, keeping precipitation to light rain as temperatures push well into the 40s. With a speedy system like this, only about a quarter of an inch of rain is expected.
You can see more green across areas like Worcester, Concord, and as far west as Springfield with this storm. A quick coating of snow is possible in those areas before a quick switch to a wintry mix, and then all rain as the day progresses.
Wednesday will see a storm come through the region beginning mid-morning and lasting through the evening.Boston Globe
Greater Boston and the entire I-495 corridor should stay with rain during the entire storm. The highest snow totals will be in the higher elevations of Northern New England, where 3 to 6 inches could be possible. The Berkshires, and near Concord, N.H., may end up with a couple of inches. The storm wraps up shortly after the commute home.
Temperatures on Wednesday will warm into the low and upper 40s across most of Southern New England. However, there will be a breeze that develops as the day carries on, with gusts of 20 to 30 mph at times, sending wind chills into the 30s during the afternoon.
