.DISCUSSION...

MONSOONAL MOISTURE CONTINUES ACROSS THE REGION. THIS MOISTURE WILL
CONTINUE TO INTERACT WITH THE AFTERNOON HEATING TO PRODUCE
ISOLATED TO SCATTERED THUNDERSTORMS ACROSS THE AREA UNTIL SUNDAY.
A COLD FRONT IS EXPECTED TO ARRIVE ON SUNDAY AND THIS WILL PUSH
MOST OF THE MOISTURE AWAY FROM THE REGION AND DROP THE
TEMPERATURE A COUPLE OF DEGREES. THE COOL DOWN WILL BE SHORT LIVED
AS WARM AIR IS EXPECTED TO QUICKLY BUILD BACK IN NEXT WEEK. GFS
AND EUROPEAN CONTINUE TO SHOW THAT THE MONSOONAL MOISTURE WILL BE
CLOSE TO THE REGION...CLOSE ENOUGH TO SUPPORT SLIGHT CHANCES FOR
THUNDERSTORMS NEXT WEEK.

AGAIN THIS AFTERNOON AND EVENING. THE STORMS WILL HAVE THE POTENTIAL
TO PRODUCE GUSTY WINDS IN EXCESS OF 50 MPH ALONG WITH LOCALLY HEAVY
RAIN. KBYI AND KSUN WILL BE THE MOSTLY LIKELY TAF SITES AFFECTED BY
THUNDERSTORMS THIS EVENING. VFR CONDITIONS WILL BE THE RULE OUTSIDE

&&

COAST THE PAST FEW DAYS WILL MOVE SLIGHTLY INLAND OVER WASHINGTON
