Sunday Evening Storm Update: As Rain Changes to Snow, Briefly Heavy Snow Rates Expected

As a quick-hitting winter storm grips New England, snow is beginning to take over from rain, thanks to a shift in winds and plunging temperatures. While the storm’s path has been consistent with earlier forecasts, tonight’s updates offer fine tuning of timing, totals, and the Arctic blast following close behind.

The Current Setup

After a mild day with temperatures in the 40s, much of southeastern New England started with rain. However, colder air is already pushing south, flipping precipitation to snow across western and northern New England. By 9 PM, areas like Boston will see snow as the rain-snow line collapses south and east.

Visibility has already dropped in parts of central Massachusetts, western Connecticut, and New Hampshire, thanks to steady snow in these areas. Maine is also transitioning, with totals expected to climb as the storm progresses.

Snowfall Totals and Rain-Snow Line

Please be sure to see the map in Matt’s forecast video for full details, but current estimates suggest the following accumulations by storm’s end:

  • Outer Cape and Nantucket: Coating to 1 inch.
  • Cape Cod Canal: 1–2 inches.
  • Boston and South Shore: 3–5 inches.
  • MetroWest and Central New England: 5–8 inches.
  • Western Massachusetts and Southern Vermont: 8–12 inches, especially in higher elevations.
  • Midcoast and Eastern Maine: Locally 8–12 inches.

The heaviest snow rates of 1–2 inches per hour will occur for most between 9 PM and 1 AM, making travel treacherous. Snow tapers off for most of New England by 3-5 AM Monday…sooner for some and later in Maine.

Arctic Air and Dangerous Wind Chills

As the storm departs, Arctic air rushes in behind it, dropping temperatures to the single digits and teens by Monday morning. Winds gusting to 30 mph will drive wind chills below zero.
