Frosty Morning

Temperatures this morning were about 15° cooler than yesterday morning, but tonight and tomorrow morning will be even cooler, even a little chilly. The cloud cover this morning will decrease through the afternoon and we end the day with sun. As a low pressure system departs to the east the pressure gradient will decrease allowing the gusty winds from this afternoon to die down. With the combination of lighter winds and mainly clear skies, temperatures will cool back into upper 30s and possibly even chillier for portions of southern Wisconsin, and we could wake up to patchy frost tomorrow morning.

There is a frost advisory in effect for southern Wisconsin starting at midnight tonight through 7:00am Wednesday morning. You'll want to cover any sensitive plants tonight before you head to bed.
