Snow bands are tightening across the Mid-Atlantic and New England coast this morning, and conditions are poised to deteriorate fast along the I-95 corridor. What falls as light flakes early will intensify by late afternoon, with snowfall rates climbing to 2 to 3 inches per hour in eastern Massachusetts. Wind already whistles off the harbor, and stronger gusts are on the way.
According to the National Weather Service, a rapidly strengthening coastal low may undergo bombogenesis as it tracks north. If pressure drops 24 millibars in 24 hours, blizzard conditions will likely develop from north of Baltimore through Boston. Nearly 54 million people sit under Winter Storm or Blizzard Warnings. Gusts could reach 50 to 70 mph, creating near-zero visibility at times.
In Boston, Worcester and Providence, plow crews are staging equipment now. A slight track shift east would trim totals. A closer coastal path could deliver 24 to 36 inches by Monday afternoon. I-90, I-93 and Route 128 may become impassable during peak snowfall. Plan extra time. Avoid unnecessary travel once heavy bands set up.
Coastal flooding is also possible during high tide cycles. Secure outdoor items and charge devices. Power outages may affect thousands if winds topple trees onto lines.
By Monday evening, snow tapers quickly. Cleanup begins, but flash freezing may refreeze slush as temperatures hover near freezing.
Five Day Outlook for Boston, Massachusetts:
Monday: Heavy snow early, then gradual clearing late. Highs near freezing.
Tuesday: Improving conditions, lighter winds. Highs in the 30s.
Wednesday: Brighter skies. Highs mid-30s.
