- Sub-freezing temperatures will occur between 9 pm and 9 am MST with hard freeze conditions between 11 pm and 9 am MST.
- Near record lows will see killing temperatures for some vegetation as well as very hazardous cold for people and pets tonight. Most unprotected exposed water pipes will freeze with these very cold temperatures.

A Hard Freeze Warning means widespread temperatures at or well below 28 degrees are expected, with Sub-freezing Temperatures Expected for many hours. To prevent freezing and possible bursting of outdoor water pipes, they should be wrapped. Drained, or allowed to drip slowly. Those that have In-ground sprinkler systems should drain them, and cover Above-ground pipes to protect them from freezing. These conditions will also kill crops and other sensitive vegetation.
