Massachusetts is in for plowable snow this weekend, but when exactly will it hit?

“Snow arrives in Hartford-Springfield area around 7 p.m. then spreading into Boston-Providence corridor by 10 p.m.,” the National Weather Service said Saturday morning. “However heavy snow delayed a few hours arriving just before or after midnight.”

The snow is expected to transition to rain, freezing rain, and sleet in parts of the state Sunday morning, before changing back to snow Sunday afternoon, the service said. Areas southeast of Boston are forecast to see rain Sunday morning, while areas west and north of Boston are in for a wintry mix. In Western Mass. and northern parts of Central Mass., where the highest projected snow totals are, it’ll remain snow throughout, according to the service.

With the changing temperatures, service forecasters say a “flash freeze” is possible Sunday afternoon across all of Southern New England.

All of Massachusetts, except for Cape Cod and the Islands, will be under a winter storm warning or watch for the duration of the storm.
