.DISCUSSION...Onshore flow will bring a cooling and moistening trend
to Southwest California tonight through Sunday as an upper trough of
low pressure moves over the West Coast. Onshore flow will continue
through Monday as the trough moves further inland. A deepening marine
layer will bring low clouds and fog through the L.A. County
valleys...approaching the Clear Creek Rx location. There is a small

to 20 mph. Increasing northwest flow is expected Monday night with
gusts 25 to 30 mph in the Clear Creek area.
