Remember those dog days of summer when things felt like they would never cool down?

Well, we’re there — it has cooled down. Way, way down.

The National Weather Service has warned that Arctic air is pouring into New England following the storm system that went through the region this weekend. That air will produce windchills expected to drop between minus 10 and minus 25 degrees in Greater Boston.


“Today will not be the nicest day to spend outdoors,” forecasters warned early Monday.

The weather service has issued a windchill advisory for the area that will remain in effect until 8 a.m. Tuesday.

Forecasters cautioned that dangerous, icy road conditions remain a risk for the morning commute, especially in areas still frozen over from Sunday’s rain and sleet. The weather service doesn’t expect temperatures to climb above freezing for at least the next 48 hours, so even once roads are treated, they suggest drivers around the region take it slow Monday.

Going outside at all Monday could be dangerous if you’re not dressed appropriately. The wind chills could cause frostbite on any exposed skin in as little as 30 minutes, the weather service said.
