A cold front will move across the region this afternoon, bringing unseasonably cold air through at least Wednesday. Temperatures will warm slightly by the end of the week, and heavy showers and winds are possible on Friday, according to the National Weather Service.
“Temperatures today will be below average, and will fall into the lower 30s and even the 20s in the suburbs outside of Boston overnight,” said Charlie Foley, weather service meteorologist.
Today will be mostly sunny, with a high around 58. A few clouds could develop by midday, and a southwest wind will bring gusts near 30 miles per hour, according to the weather service. A few sprinkles could pop up in western regions, but no significant rain is expected.
Tuesday will be mostly sunny, with unseasonably chilly temperatures in the upper 40s. Light winds will blow through the day and the southeast coast will see clouds developing and a few morning sprinkles, according to the weather service. Temperatures will fall into the upper 30s overnight, and clouds will increase.
Clouds will dominate the skies Wednesday, and precipitation, including a bit of snow, is possible. Some white flakes could fall in the north and west, especially in higher terrain, while other areas will see rain, according to the weather service. Daytime temperatures will crest at around 50 and will fall to around 40 overnight. As fans descend on Fenway Park for Game 6 of the World Series, temperatures will be chilly, so an extra layer is recommended.
Thursday will see a mixture of clouds and sun, and showers will likely develop after 11 a.m. Temperatures will climb to around 60 this Halloween, and will fall into the mid-50s overnight. In the early evening — the prime hours for trick-or-treating and perhaps ending the World Series — rain is likely, but the night won’t be a washout. Some intense winds will develop late Thursday into early Friday, bringing gusts up to 45 miles per hour.
“There could be significant precipitation Thursday, but rain should fall late enough for the kids to get out, get their candy, and not get impacted that much,” Foley said. “But some heavy rain could come at the end of the World Series.”
Widespread rain is likely Friday, and a few rumbles of thunder cannot be ruled out. The heaviest rain could likely come to northern parts of the region. Daytime temperatures will reach the mid-60s, and fall to around 50 overnight.
The weekend should be fairly nice, with mostly sunny skies expected for Saturday and Sunday. Temperatures through the weekend should hover in the upper 50s, and no rain is expected, according to the weather service.
