Drive carefully today. Those roads might be slicker than you think.
A weakening cold front will slide offshore this morning, allowing rain and freezing rain to move over southern New England today. Dry and colder weather arrives Christmas Eve and should persist through Christmas Day, with snow showers around Boston unlikely until Thursday, according to the National Weather Service.
“We could see one-tenth of an inch of ice today,” said Glenn Field, weather service meteorologist. “When we get to a half-inch, that’s when we see power lines coming down and roads becoming bad. We are expecting temperatures to warm up just enough after noon, but if they don’t, there could be problems.”
A mixture of rain and freezing rain will fall through the state this morning, but should transition to all rain after 1 p.m. The weather service has issued a freezing rain advisory for northeastern Massachusetts, including Boston. Skies will remain mostly cloudy through the day and temperatures will settle in the upper 30s. Rain will continue through the evening and temperatures will fall into the low 20s.
Tuesday will be dry and blustery. Conditions will be partly sunny with a high near 32, according to the weather service. A northwest wind will gust near 11 miles per hour through the day. A few late-day snow showers are possible for the outer Cape and on Nantucket, but no significant precipitation is expected. Temperatures will fall into the teens overnight, and winds will strengthen slightly, gusting around 15 miles per hour.
“It’s going to be very cold on Christmas Eve, with temperatures in the mid-teens, including in Boston,” Field said. “On Christmas Day, we will get into the mid-20s if we are lucky.”
Christmas Day will be sunny and a northwest wind will gain strength in the afternoon, gusting around 13 miles per hour. Clouds will develop overnight, and temperatures will fall into the low 20s. A few leftover snow showers could fall on the outer Cape, from Provincetown to Chatham. Besides that, no snow is expected throughout the region, according to the weather service.
“We will have a cold front coming through during the day Thursday,” Field said. “Along with that brings a chance of some precipitation, but it’s not going to be a big storm.”
Thursday will be partly sunny and temperatures will crest around 40. A few scattered rain and snow showers are possible during the day, but less than an inch of precipitation is likely. Clouds will develop overnight and temperatures will fall into the 20s.
The sun will continue Friday, with temperatures settling in the mid-30s. Skies will remain clear overnight, with temperatures falling into the mid-20s. Dry and cold conditions will continue through the weekend, according to the weather service.
