Officials issued a wind chill advisory Wednesday in the White Mountains with temperatures expected to drop below freezing and snow in the forecast.

“The calendar might read mid-May but the White Mountains will feel more like late March,” Mount Washington Observatory officials wrote on Twitter. The wind chill advisory is in effect until Thursday morning.

On Wednesday, the wind chill is expected to fall to single digits, with gusts reaching up to 70 mph in the evening, officials said. At elevations above 4,000 feet, more than 3 inches of snow could fall, according to a forecast from meteorologist Ryan Knapp on the observatory’s website. Lower elevations will receive up to 1 inch.


Snow is expected to taper off Wednesday night, Knapp said. On Thursday, temperatures will rise to the lower 30s but “will remain well below normal for mid-May,” he wrote. The wind chill advisory is set to expire at 8 a.m.

Knapp cautioned hikers seeking to traverse the mountains while the warning is in effect.

“This will reduce exposure and hypothermia times to a matter of minutes if not adequately prepared for winter hiking,” he wrote.

Much of Massachusetts will experience a blast of cold weather Wednesday, the National Weather Service said. The region will experience “gusty winds” and “cooler-than-normal highs,” as well as below-freezing temperatures into the night, according to a forecast discussion. A freeze watch was issued for Wednesday night and Thursday morning over the western part of the state.
