Wind chill values will remain in the subzero region until Saturday, when temperatures will rise to about 25 degrees. There’s a strong likelihood of a wintry mix of snow, sleet, and rain Saturday night and Sunday, according to NWS. That could exacerbate the danger of roof collapses, as the region has seen about 5 feet of snow in February alone.
