The National Weather Service released a freeze warning at 12:27 p.m. on Monday valid from Tuesday 10 p.m. until Wednesday 10 a.m. for Larimer County below 6,000 feet/Northwest Weld County, Boulder/Jefferson counties below 6,000 feet/West Broomfield County, North Douglas County below 6,000 feet/Denver/West Adams and Arapahoe counties/East Broomfield County and Elbert/central and east Douglas counties above 6,000 feet.

The NWS comments, “Take steps now to protect tender plants from the cold. To prevent water pipes from freezing; wrap or drain or allow them to drip slowly.”

Freeze watch or warning – this is what it means

Freeze warnings are issued from May to October (but can be extended if necessary), when low temperatures are expected to be 29-32 degrees. If there is a potential for temperatures to fall into these thresholds, a freeze watch may be issued a few days ahead of time.

According to the NWS, if a freeze warning or watch is issued for your area, there is little you can do to protect plants. If you can move your sensitive plants inside, do so because the freeze will likely kill them, depending on the severity of conditions.
