Bring in your pets and sensitive plants (or cover them if you can’t bring them in) as the first freeze of the season is expected tonight into Saturday morning to close out climatological fall and welcome in climatological winter on December 1. Temperatures will fall into the low 30s across much of the metro by morning, and a Freeze Warning is in effect for the entire Tri-County area as a result. Despite several days of cold air ahead, including even colder air next week, this will be the only Freeze Warning of the season as the growing season will come to an end on December 1, regardless of how far to the east freezing temperatures penetrate. Frost and freeze alerts resume on March 1, 2025.

After that very chilly start, we’re warming to only the mid-50s in the afternoon despite mostly sunny skies. Northerly winds 5-10 MPH will keep temperatures feeling like the mid-40s through early afternoon.

Winds go calm overnight Saturday into Sunday morning, and we’ll see another very chilly morning as a result, with the potential for widespread frost particularly inland. Lows should bottom out in the low 30s once more. (If it doesn’t freeze again, it’ll be close.) Highs will recover a bit to the upper 50s on Sunday afternoon, but that’s still well below normal for the first of December.

We have another shot of even colder air in store for early next week, with lows in the 20s across the metro possible Tuesday and Wednesday mornings. Tuesday may not even get out of the 40s! Colder-than-normal temperatures and rain-free conditions look to continue through next Friday.
