After a relatively mild Saturday night, residents should prepare for increasing clouds and a light wintry mix on Sunday as a powerful Arctic blast prepares to send temperatures tumbling on Monday.
The last of Saturday’s rain and clouds are quickly moving offshore by the afternoon, paving the way for a drier air mass, according to the National Weather Service. Saturday night, skies will clear, providing a calm end to the weekend before the next system moves in.
Temperatures Saturday night are expected to remain mainly in the 20s.
Coastal areas like Hyannis can expect a low of 30 degrees, while Boston is supposed to drop to 26 degrees under mostly clear skies.
Inland areas will experience temperatures in the upper teens and low 20s, including Worcester, 22 degrees, and the western cities of Springfield, 18 degrees and Pittsfield, 19 degrees.
Since most of the state is falling below freezing Saturday night, residents should be mindful of any lingering melted snowpack that could refreeze and create slick spots.
Sunday will feature a mix of clouds and sun, with the best chance for sunshine during the first half of the day. Clouds will then steadily increase through the afternoon ahead of the weak disturbance and a cold front moving into northern New England.
This system is expected to bring a chance of light snow showers late Sunday night, mainly confined to areas north of the Massachusetts Turnpike.
Accumulations will be minimal, and a simple coating is expected. At most, this region could see half an inch, forecasters predict.
The bigger change will be the drop in temperature on Sunday night. Ahead of the arctic front, temperatures will likely fall into the teens and low 20s, making it noticeably colder than Saturday night, forecasters report.
Arctic air is then set to arrive on Monday, bringing well-below-normal temperatures to kick off the work week.
