The big chill is credited to a lack of cloud cover combined with artic air from the Pacific Northwest. Monday afternoon temperatures are expected to be in the mid-to-low 60s in most areas, with some mountain regions possibly dipping into the 30s.
"It's a perfect day to go to Big Bear. Chilly, but lots of new snow up there," said NBC4 meteorologist Byron Miranda.
Historically, the average high for Dec. 5 is 70 degrees.
A freeze watch was issued for Ventura County through Tuesday morning.
The remainder of the week will remain chilly with overnight lows expected to stay in the low 40s.
