FLOSSI AND THE FROZEN FORECAST

United States and southern Ontario, Canada, were under winter weather warnings as snow squalls moved through Thursday morning ahead Arctic temperatures blasting through the region with blustery and potentially damaging wind gusts.

After a week of bitterly cold temperatures and days of lake-effect snow, another shot of cold air swept through the Northeast, sending temperatures in parts of the Midwest plunging into the teens, 10 to 20 degrees below normal. Wind gusts up to 80 miles per hour are expected Thursday afternoon into the evening, bringing blizzard conditions to areas with lake-effect snow and making travel treacherous.

Forecasters with the National Weather Service in New York City said Thursday night into Friday would be the coldest night and early morning of the season, especially after accounting for wind chill.
