'Flash Freeze' May Hit MA With Snow Continuing: Weather Advisory

MASSACHUSETTS — Hazardous travel conditions may persist through Thursday and into early Friday in Massachusetts as a drop in temperatures runs into continuing precipitation.

Massachusetts is under a winter weather advisory until 4 a.m. Friday with up to an inch of snow accumulation possible during that time, according to the National Weather Service.

But a rapid drop in temperatures beginning around noon Thursday may cause a "flash freeze" of snow and sleet that's already fallen across the state.

"Cold air over VT & NH drains southward today, temps fall below freezing in northern portions of MA, CT & RI. This will result in a flash freeze, with any standing water or slush, freezing later this morning into the afternoon & evening. Icy spots will develop," the National Weather Service said in a tweet Thursday morning.

Temperatures could drop by about 10 degrees between Boston and Worcester around noontime, according to forecasts. Within about an hour, the temperature could go from 32 in Worcester to 20. By the Thursday rush hour, temperatures will be in the low 20s across the region.

Up to 2/10 of an inch of ice may accumulate on top of snow that's been falling since Thursday night, according to the weather service.

Friday will be mostly dry, but temperatures will be very cold, falling into the single digits across the state by sunset, according to the weather service.
