A two-part storm is predicted to bring a wintry mix to the Boston region this weekend then winds “strong enough to blow over small trees” on Monday, according to the National Weather Service.

Rain is approaching the Northeast from the South, while air circulation is coming in from the Southwest, meteorologist William Babcock said Friday. The two weather systems will become one unified storm before moving into New England.

“It’s going to pick up all that moisture of the southern U.S. and then it’s all going to move north,” he said. “The storm itself is moving into the Great Lakes, but all that moisture, all that rain, is going to move north, and it runs into the colder air over New England.”

Boston will get a mix of snow, sleet, and rain starting around 2 a.m. Sunday, according to the service. The precipitation will change to rain around 3 a.m. Sunday as temperatures increase. Western Massachusetts will start seeing the wintry mix much earlier, around 10 or 11 p.m. Saturday, Babcock said.

The city’s forecast includes an inch of rain, less than an inch of snow, and no ice, according to maps from the service.

Winds Sunday night through Monday are part of the same system. The service predicts Boston could have maximum wind gusts of 40 to 45 miles per hour, while areas along the Massachusetts coast, including Cape Cod, could clock higher speeds. Gloucester and Plymouth could see gusts of 45 to 50 miles per hour, while Chatham and Provincetown could see gusts between 50 and 55 miles per hour.

Some trees could be knocked down as a result, according to Babcock.

“I don’t see it turning New England into the prairies so, I mean, it’s not going to be like that,” he said. “But it will probably knock over a couple of trees here and a couple of trees there.”
