A freeze watch has been upgraded to a freeze warning for a big portion of Lower Michigan.
The freeze warning starts at midnight Wednesday and lasts overnight into Thursday at 8 a.m., as temps are expected to dip into the 30s.
The freeze warning will be in effect for the southern half of Lower Michigan, from Bad Axe to Mt. Pleasant, west through Pentwater, and including all of Southeast Michigan and West Michigan.
What’s a freeze warning?
A Freeze Warning is issued when significant, widespread freezing temperatures are expected.
A Freeze Warning is issued in the spring at the start of the growing season (when it is late enough to cause damage to new plants and crops).
Freeze Watch vs Warning
- Hard Freeze Warning: Take Action! NWS issues a hard freeze warning when temperatures are expected to drop below 28°F for an extended period of time, killing most types of commercial crops and residential plants.
- Freeze Warning: Take Action! When temperatures are forecasted to go below 32°F for a long period of time, NWS issues a freeze warning. This temperature threshold kills some types of commercial crops and residential plants.
- Freeze Watch: Be Prepared: NWS issues a freeze watch when there is a potential for significant, widespread freezing temperatures within the next 24-36 hours. A freeze watch is issued in the autumn until the end of the growing season and in the spring at the start of the growing season.
