DISCUSSION:

An unseasonably cold storm system will brush the area over the
weekend. There a high-to-likely chance of rain across the area
Saturday afternoon through early Sunday. Rainfall amounts will
likely be around a quarter inch or less, except a quarter to half
inch across northwestern San Luis Obispo County. Snow levels will be
fairly high initially, but will lower to between 4000 to 5000 feet
over Ventura and Los Angeles Counties by Saturday night. However, at
that time only light snow amounts will be possible.

NOTE: This a special issuance due to the threat of rain. Routine
issuances of this product will resume Nov 1. If widespread rain is
expected before then additional forecasts will be sent out.
