First freeze warning of season Monday morning

Sunday morning we had plenty of frost, especially in inland communities. Low temperatures Sunday morning were even below freezing in some isolated spots but most woke up to lows in the lower 30s. Milwaukee lucked out with a lake breeze keeping them a little warmer with a low of 40°.

Thanks to a cool day, overnight temperatures will drop quickly and most of southeast Wisconsin will see lows around or near freezing by Monday morning. The National Weather Service has issued a freeze warning for the entire CBS 58 viewing area from midnight until 8 AM Monday. 

Lows Monday morning will be coldest in inland spots where some isolated upper 20s aren't out of the question. Most of us will wake up somewhere between 30-34° which is cold enough to kill some sensitive plants.

If you've already done some spring planting it will be a good idea to cover them with a blanket or upside down pot. Watering the plants before the freeze arrives also helps because the evaporating water actually warms the plant slightly.
