Hour-by-Hour to 7 Degrees Below Zero

It looks like the holiday weekend will have a burst of snow Friday night and the potential for a few inches on Monday.

But the big story for Saturday and Sunday will be dangerously cold temperatures as cold air and high winds settle in, according to the National Weather Service.

The wind chill, or “feels like” temperature, will stay in the single digits all day Saturday and drop below freezing Sunday — as much as 7 below in parts of the region.

A wind advisory will be in effect from 3 a.m. until 6 p.m. Saturday for most of the region, with wind gusts possibly reaching up to 50 mph.
