Freeze Watch for Friday

Thursday Evening Update:  The Freeze Watch has been extended to include all northern Illinois and southern Wisconsin counties.  Remember to bring in the plants you can and want to keep and pick any veggies left in the garden.  Temperatures both nights drop into the upper 20's.





Original Post Thursday Morning:

A passing cold front on Thursday, along with a building high pressure system, will bring chilly temperatures to the Stateline for the weekend. As the high pressure system sinks south from Canada, it will bring a chilly Canadian air mass with it. This combined with breezy northerly winds will reinforce the cold air keeping the cold snap with us through the weekend. Overnight lows on Friday night into Saturday morning will fall below freezing, into the upper 20's. This has prompted the National Weather Service to issue a Freeze Watch for Winnebago, Boone, McHenry, Ogle, Lee, and DeKalb counties late Friday night until 9am Saturday morning. Along with the freeze watch you will also wake up to areas of frost Saturday and Sunday morning. It will still be cold as you wake up on Sunday, with temperatures near freezing at 32°.

Though southern Wisconsin and our western counties aren't included in the freeze watch just yet, I wouldn't be surprised if the watch was expanded coming up later today or by Friday.

The cold snap won't last long, temperatures make it into the upper 50's by Sunday afternoon and then into the mid 60's by Monday.
