The National Weather Service issued a Winter Storm Warning for inland Massachusetts for Wednesday into Thursday, which it expanded Wednesday afternoon to include the Boston metro area.

“A major winter storm today into early Thursday will bring heavy, wet snow and the potential for power outages across interior southern New England,” the service said. “Mainly heavy rain and strong winds will occur along and southeast of the Boston to Providence corridor, with the potential for some renewed river/stream flooding.”


Service forecasters said Wednesday afternoon that the snow forecast for the I-95 corridor remained uncertain, even as totals were “nudged upward” from initial predictions.

“Keep in mind uncertainty remains HIGH in the outlined area, since surface temperatures will be key to accumulating snow or melting,” the service said of the I-95 corridor. “In these areas, especially in the cities, slushy accumulations are expected on roads, with most accumulations on grass.”

Most of the storm’s accumulation is expected to take place between 6 p.m. and midnight, according to the service.
