Temperatures are expected to take their first real tumble this week — from a high near 60 Tuesday to a low in the 20s Saturday — with a chance of the season’s first snowfall Friday.

Conditions are expected to change markedly over the week, following a sunny, breezy Sunday with a high temperature that reached 57 degrees in Boston, according to the National Weather Service.

After a series of likely highs near 60 through midweek, the coldest air since last winter is expected to arrive Thursday night, setting up a possibility of snow, forecasters said.

With the low Friday morning expected to drop into the low 30s, the 30 percent chance of precipitation may come as a snow shower, according to the weather service.


“It is still generally wavering around snowfall event potential,” said Bryce Williams, a meteorologist at the weather service, who said the forecast is not yet clear.

Higher elevations in the state — the Berkshires and Worcester Hills — have the best chance of snow, simply because the cooler temperatures, he said in a phone interview.

“It is definitely going to be cold,” Williams said. Winds are expected to gust up to 14 miles an hour with a high in the upper 30s and a low near 26 on Saturday evening, according to the weather service.

Some precipitation is also possible from Monday night through Tuesday afternoon, according to the weather service.
