Cold Air
The Weather Prediction Center has highlighted extensive colder than average temperatures Sunday through Monday as cold Canadian air follows the upper level low and is dragged all the way into Southern California!

Temperatures will drop into the 20s and 30s during the overnight hours the next several mornings, certainly cold enough to support even snow at lower elevations. There are hard freeze warnings for Southern Humboldt Interior and Southern Trinity Counties in California with temps expected to fall in the upper 20s, along with much of Utah. Freeze watches and warnings have been issued for the Denver and Tucson metros, for Monday and Tuesday mornings, respectively.

Cover plants that are outside or bring them inside, and make sure outdoor animals have a warm place to go.
