Down to 32 here and also at MLI. Over in LOT it's 27 in Sugar Grove with several upper 20s around. Looks like a freeze warning was warranted. Hopefully folks covered up their plants anyway with the frost advisories being issued etc.
Looks like Mon and Tue may be as cold in some areas.
I went back and looked at the weather station data. Didn't have any freezes after April 30th from 2016-2019, last year we had 1. This May we could have 3.
EDIT: Now also looks like Wed morning also has freeze potential. 4 freezes in May? Wow
