THE NEXT SEVERAL DAYS. TO AGGRAVATE THE ISSUE...WILL HAVE A FEW
ISOLATED THUNDERSTORMS NEAR AND OVER THE CASCADES THIS EVENING.

WINDS WILL PICK UP LATER FRIDAY...AND CONTINUE INTO EARLY SUNDAY.
HOWEVER...WINDS WILL NOT BE AS STRONG AS THOSE LAST WEEKEND...BUT
EXPECT VERY WARM CONDITIONS AND LOW HUMIDITY. THERMAL TROUGH WILL
SHIFT OVER THE INTERIOR ON SUNDAY...THEN REBUILD EAST OF THE
CASCADES LATER SUNDAY NIGHT AND MONDAY. IT WILL BE ON SUNDAY THAT
WORST CONDITIONS CAN BE EXPECTED OVER THE CASCADES...WITH MOST
UNSTABLE AIR AT THAT TIME. WILL SEE RELIEF TO HEAT AND DRY AIR AT
LOWER ELEVATIONS BEGINNING SUNDAY NIGHT.

LONGER RANGE CHARTS SHOW A GRADUAL RETURN TO ONSHORE FLOW NEXT
WEEK...WITH A RETURN TO MORE SEASONABLE TEMPERATURES AND HUMIDITY.
