A freeze warning has been issued by the National Weather Service Office in Sacramento for communities below 2,000-feet elevation in the Central Valley.
Another chilly night is forecast Tuesday for the Sacramento region before rain clouds move in from the Pacific Ocean. A Canadian airmass is moving into the valley, bringing subfreezing temperatures.
Readings in the Central Valley are expected to dip into the upper 20s and lower 30s overnight. The freeze warning has been issued from midnight to 9 a.m. Wednesday.
A freeze warning means sub-freezing temperatures are likely, according to the NWS. Freezing conditions can kill crops or sensitive residential landscaping.
The weather service advises residents to protect exposed water pipes and provide a warm spot for pets to get through the night.
