After more than a foot of snow has in Belmont in the past 18 hours, the fourth storm in the past three weeks is expected to end at noon, Sunday, Feb. 15 with a peek of sunshine expected this afternoon.

Nearby Lexington picked up 16.6 inches of snow while Winchester saw 13 inches fall, according to the National Weather Service.

But the departing storm will open the door for some of the coldest temperatures in recent history as well as wind chills reaching -30 to -45 below Sunday night that will make it dangerous to be outside for any period of time.

The National Weather Service has issued a wind chill warning, which is issued when the wind chill index is likely to fall to -25 degrees or colder for at least 3 hours. A wind chill index below -30 can bring about frostbite in as little as 10 minutes. 

Residents can expect lows below zero tonight, Sunday and Monday, Feb. 16, with northwest winds blowing steadily at 25 to 35 mph with gusts up to 65 mph.

The NWS advises that outdoor exposure should be limited. If you are heading outdoors, dress in layers and keep your hands and head covered to protect against frostbite.
