 Special Weather Statement 
Statement as of 9:15 am PDT on May 22, 2008


... Cool and unsettled weather through Memorial Day weekend...

A developing low pressure system will bring cool and unsettled
weather with a chance of showers and thunderstorms today through
Sunday. The best chance for showers and thunderstorms will be over
the mountains. People with outdoor activities should expect periods
of showers or thunderstorms during the Holiday weekend.
Thunderstorms contain deadly lightning and may produce brief heavy
rain... gusty winds... and small hail. Snow is possible above 7000
feet in the san gorgonio wilderness and on mount San Jacinto.
Rainfall amounts will be highly variable due to the showery nature
of the precipitation.

The weather will be considerably cooler than last week with high
temperatures running 10 to 20 degrees below seasonal averages.
Interested parties should stay informed on the latest forecast.
