SHORT TERM...TODAY THROUGH SUNDAY NIGHT...THE UPPER RIDGE THAT HAS
BEEN OVER THE PACIFIC NORTHWEST ON THURSDAY WILL SHIFT EASTWARD

AS THE UPPER TROUGH MOVES INTO THE CASCADES THIS AFTERNOON THE
THERMAL SURFACE TROUGH WILL MOVE EAST AND TEMPERATURE GRADIENTS WILL
TIGHTEN ACROSS THE CASCADES WHICH WILL IN TURN RESULT IN TIGHTENING
SURFACE PRESSURE GRADIENTS. AS SUCH CAN EXPECT INCREASING WINDS OVER

LATER TODAY. WINDS WILL ALSO INCREASE THIS AFTERNOON IN THE KITTITAS
VALLEY. THERE WILL BE VERY LIMITED MOISTURE WITH THE COLD FRONT

ANY THUNDERSTORMS ON TUESDAY AND SEE WHAT FUTURE RUNS SHOW.  A DRY
WESTERLY FLOW IS PROGGED OVER WASHINGTON MON AND TUES THEN OVER THE
REMAINDER OF THE AREA WED AND THURS.  THIS WILL SUPPRESS ANY
MONSOONAL MOISTURE TO THE SOUTH.   OVERALL...A DRY FORECAST IS IN
STORE THROUGH THE EXTENDED PERIOD WITH TEMPERATURES NEAR OR ABOVE
