Patchy Frost Possible Friday Morning
A Frost Advisory has been issued for Stephenson, Jo Daviess and Green counties beginning overnight and lasting through early Friday morning.
Skies will likely remain mostly cloudy but a few breaks in the cloud cover could allow for temperatures to fall into the mid 30's, causing patchy frost to develop. I do not think this is a widespread threat as cloud cover from the southwest will quickly fill in, but if you do have sensitive plants or vegetables that have begun to emerge it may be a wise idea to cover them just to be on the safe side.
We are actually pretty close to when we experience our average last spring freeze. Typically this occurs towards the end of April - right around April 28th in Rockford. The earliest spring freeze occurred on April 7th and the latest spring freeze occurred on May 27th.
