Mostly clear and very dry conditions will allow temperatures to fall into the 30s in the lower desert areas.

The National Weather Service advised that pets should be brought indoors, and sensitive plants may be damaged or killed if left uncovered.

However, Santos said that by Friday, temperatures will drop back to the low to mid 60s for the coast and valleys as a trough of low pressure moves into the Great Basin. The weekend will see a warm up into the low to upper 70s.  The warming trend is forecast to last into early next week.
