.DISCUSSION...

A STRONG UPPER-LEVEL RIDGE OF HIGH PRESSURE WILL DOMINATE THE
REGION THROUGH THE WEEK WITH ABOVE AVERAGE TEMPS AND LOW DAYTIME
RHS. LOOK FOR LIGHT TERRAIN DRIVEN WINDS AND MOSTLY CLEAR SKIES
ASIDE FROM SMOKE.  A THERMALLY INDUCED PRESSURE TROUGH WILL
SETUP ALONG THE EAST SLOPES OF THE CASCADES TUESDAY THROUGH
THURSDAY...LEADING TO AN UNSTABLE AIR MASS AND POOR RELATIVE
HUMIDITY RECOVERIES.  A DISTURBANCE UNDERCUTTING THE RIDGE EARLY
NEXT WEEK MAY BRING THE NEXT CHANCE FOR WINDIER CONDITIONS AND
PERHAPS THUNDERSTORMS. CONFIDENCE IS VERY LOW REGARDING THE DETAILS
OF THIS FEATURE.
