    Boston has been experiencing summer-like temperatures this fall, but frost is expected Friday morning.

    Chilly temperatures and the first frost of the season are expected to blanket much of the state Friday morning, before giving way to warmer weather into the weekend, the National Weather Service said.

    “It’s just going to be a crisp, autumn morning” Friday, weather service meteorologist Kim Buttrick said.

    The weather service issued a Frost Advisory covering most of Massachusetts for 3 a.m. to 8 a.m. Friday and said temperatures throughout the state could fall close to freezing, in the low 30s.


    Coastal Massachusetts is exempt from the advisory, as temperatures there are expected to remain in the low- to mid-40s.

    “It’s kind of a tickle or taste for winter to come,” Buttrick said.

    The main risk of the frost is to the health of weaker plants that Massachusetts residents may still have out in their yards, Buttrick said, as well as slippery conditions on surfaces coated by frost.

    “Lower to the ground, it actually could be cooler, so that’s why we say if you have tender vegetation you want to cover it or you want to bring it in,” she said. “You could have some slick spots, you could have frost on plants, on sidewalks, on cars.”

    The mid-October frost is fairly typical for the state, Buttrick said. Western and Central Massachusetts usually see the first fall freeze around Oct. 1, southern areas “below the Mass Pike” around Oct. 11, and “later in the month” for Eastern and Southeastern Massachusetts.


    “It’s close to normal,” Buttrick said. “This is when we would expect to have frost advisories.”

    While early morning commuters will get their first taste of winter Friday morning, Buttrick said conditions will warm into the weekend.

    “We’re expecting seasonable temperatures ranging in the 60s, and then Friday night it won’t be as cool,” with temperatures around 50 degrees, she said.

    Temperatures this weekend are “going to turn warmer,” Buttrick said, with highs reaching into the 70s Saturday and Sunday, and a chance for showers both days.
