The streak of below-freezing temperatures started in metro Denver at 4 p.m. Monday and is forecast to break around noon Thursday, forecasters said.

Temperatures cool off into the upper 30s and lower 40s on Saturday under partly cloudy skies. While parts of the high country will see 1-3″ of snow Saturday into Sunday, the snow could make its way in the form of flurries overnight in Denver with no accumulation expected.

Due to frigid temperatures forecast throughout the week, the City of Denver is extending its cold weather shelters through Feb. 20.
