DISCUSSION:

An upper low and frontal system will bring rain to most areas
today. There will be enough instability this morning into this
afternoon for a slight chance of thunderstorms, mainly in
northern areas and in the mountains.

Rainfall totals of one quarter to three quarters of an inch are
expected across the region, with local totals up to one inch from
southern Santa Barbara County through Ventura County and into
western Los Angeles County. Snow levels will be between 4500 and
5500 feet.
