Average last spring freeze

Temperatures Thursday morning fell into the upper 20's and low 30's area wide, with some locations dropping into the middle 20's.  There were a few reports of frost this morning, but frost could be more widespread Friday morning with a lighter wind.

The weather this week has been cold, no question about that, but it's not unheard of to get freezing temperatures towards the end of April.  According to Illinois State Climatologists, the median date of the last freeze, 32 degrees, is between the 21st and 29th of April in Northern Illinois.  The median date of the last 28 degree freeze is usually within the first week and a half, to two weeks, in April.

While it's possible temperatures will fall to freezing again this Spring, we've likely got a few more possible nights of frost.  Northern Illinois has seen freezing temperatures as late as the 27th of May!
