Chilly Temps Tonight... But Why?

Despite a big warm-up in the forecast, tonight is still going to be chilly with lows in the mid 30s. So what gives? One big reason is the cloudless skies above us.

Clouds act like insulation. Under clear skies, warmer air near the ground escapes up and out into the atmosphere faster than under cloudy skies. Light winds and low dewpoints can also aid in a faster cooldown.

Fortunately, temperatures warm up quite a bit after tonight. We'll be in the mid 60s for Friday and Saturday, with 70s for Sunday through Tuesday.
