The wind chill factor could get as low as -18 on Thursday night, the National Weather Service warns.
The temperature combined with wind gusts will be so dangerously low that the National Weather Service has issued a wind chill advisory that runs from 7 p.m. on Thursday through 10 a.m. on Friday.
The advisory extends across most of eastern and central Massachusetts, including Hamilton and Wenham. An advisory is issued when wind chills are expected between -15 and -24 for at least 3 hours.
The weather service said that there is a “heightened threat of frostbite or hypothermia” for anyone that will be outside on Thursday evening and early Friday morning. The wind chill factors have been created by a combination of air temperatures between -5 and 5 and northwest winds at 10-15 miles per hour with gusts up to 35 mph.
“Remember to dress in layers and wear a hat and gloves to protect yourself from the cold,” the weather service said when it issued its advisory.
