...SCATTERED TO NUMEROUS SHOWERS AND ISOLATED THUNDERSTORMS
TONIGHT THROUGH SUNDAY...

...BREEZY WESTERLY WINDS SUNDAY...

.DISCUSSION...Warmer, drier conditions area-wide today. A low- 
pressure system from the Pacific will bring widespread showers 
and isolated thunderstorms to the region tonight through Sunday. 
Breezy westerly winds will also develop Sunday with a cold frontal 
passage. Drier conditions are then anticipated late Monday, 
followed by warming into the middle of next week.


***Thunderstorms imply strong gusty winds***
***Winds are 20 foot 10 minute averages***
***CWR-chance of wetting rain 0.10 or greater***
***Ventilation Index is derived from the
   transport wind multiplied by the mixing
   height in 100's of feet. Index categories
   are a generalized indicator and users are
   encourage to develop criteria that are 
   suitable and representative of dispersion
   conditions in their local area of interest.***
     Note: Max transport winds may not occur 
     at the same time as max mixing height.
