DISCUSSION...

A cold winter storm will develop Monday across Northern
California, then drive south across Central and Southern
California Monday night through Tuesday. This system will bring
widespread precipitation to our region.

The brunt of the storm will occur late Monday night through
Tuesday afternoon. Isolated thunderstorms during the day Tuesday
could cause isolated more intense precipitation rates, just about
anywhere.

General precip amounts will be around one-quarter to one-half
inch near the coast, to one-half to one inch in the mountains, and
around one-tenth to two-tenths inch in the deserts.

Snow amounts will be 1 to 3 inches in the high deserts and Santa
Ana Mountains, and 4 to 8 inches in the higher mountains.
