A strong cold pushes through the Chicago Sunday.  Behind the front, temperatures tumble as strengthening westerly winds usher much colder air into the region. Highs in the 60s occur early followed by temperatures falling throughout Sunday.  By late afternoon we’ll likely see temperatures in the lower 40s and even some upper 30s.  By Monday morning many locations west and north of the Chicago metro are expected to see temperatures near freezing.  

Frost and freeze conditions could kill crops or other sensitive vegetation

The flowers and other plants that have been coming on strong thanks to the summer-like weather over the last week might be in a little danger on Sunday night.  

A Freeze Watch is in effect in the blue highlight counties, including northern Cook and northern Will, Sunday 10PM – Monday 10AM.  Sub-freezing temperatures as low as 30º are possible.  

Frost and freeze conditions could kill crops or other sensitive vegetation and possibly damage unprotected outdoor plumbing.  Take steps to protect your tender plants.  Precautions should also be taken to protect outdoor water pipes and in-ground sprinkler systems.
