The Berkshire region will endure its first severe cold snap of the winter season starting Wednesday, Feb. 10, and continuing through the weekend, according to the National Weather Service.
"Very cold temperatures will combine with strong gusty winds to allow for wind chill values to reach dangerous to potentially life-threatening conditions between Saturday and Sunday night," the government forecast stated.
The return of the cold weather marks a change to the unseasonably mild temperatures that have accompanied the 2016 winter season.
Sporadic snow showers will persist tonight into Friday night, leaving about a half-inch to an inch of snow in daily and overnight bursts.
On Thursday night, the low is expected to be 5 degrees. Friday night will be around 8. Saturday night will be about minus 7, while Sunday night will be around minus 2.
Daytime highs are expected to be 33 on Wednesday, 23 on Thursday, 21 on Friday, 12 on Saturday and 9 on Sunday. On Monday, the temperature will be near 24.
