Sub-freezing temperatures overnight will harden slush and puddles, so Thursday morning’s commute in Greater Boston is expected to be slippery, according to the National Weather Service.
“Untreated surfaces with slush/water will become icy, so please take your time in the morning,” the weather service tweeted late Wednesday night.
Several communities in central Massachusetts plan to delay school openings Thursday by two hours. Fitchburg State University will also have a two-hour delay on Thursday, according to the school’s website.
Cold but sunny weather is on tap for much of Thursday, with the high temperature expected to be in the low 30s, meteorologist William Babcock said.
On Friday, highs will be in the mid-30s. Milder temperatures, in the mid-40s, and periods of rain and snow are expected over the weekend.
The warming trend comes after a wintry mix of snow, sleet and freezing rain moved across the region on Wednesday, making for slippery travel throughout Massachusetts for most of the day.
A winter storm warning remained in effect until 10 p.m. for north-central and northwestern portions of the state, according to the weather service.
