.DISCUSSION...
BROAD SOUTHWEST FLOW WILL CONTINUE TODAY AS LOW PRESSURE CONTINUES
TO SPIN OFFSHORE. TEMPERATURES WILL BE 10 TO 15 DEGREES COOLER FOR
HIGHS TODAY AS COMPARED TO MONDAY WHICH WILL SIGNIFICANTLY LIMIT
THE POTENTIAL FOR THUNDERSTORMS TO DEVELOP. THERE WILL STILL BE
A VERY SLIGHT POTENTIAL FOR ISOLATED THUNDERSTORMS...HOWEVER.
TONIGHT THROUGH THURSDAY A FRONTAL SYSTEM WILL OVERSPREAD THE AREA
WITH PRECIPITATION. BETWEEN TODAY AND THURSDAY INLAND HIGH
TEMPERATURES ARE LIKELY TO FALL ANOTHER 10 TO 20 DEGREES AND SNOW
LEVELS WILL FALL TO NEAR 4000 FEET. FRIDAY THROUGH EARLY NEXT WEEK A
GENERAL NORTHWEST FLOW IS EXPECTED.

* IT SHOULD BE NOTED THAT THE GENERAL WINDS TODAY WILL BE FROM THE
SOUTHWEST. TERRAIN INFLUENCES WERE ACCOUNTED FOR WITH POTENTIAL OF
A SOUTHEAST COMPONENT TIL LATE MORNING, THEN TURNING SOUTHWEST. THE
WIND COULD BECOME WEST TO EVEN NORTHWEST IN THE LATE AFTERNOON AND
EARLY EVENING, ESPECIALLY IN GUSTS, DUE THE COMPETING INFLUENCES
OF THE SPRAGUE RIVER DRAINAGE AND THE SOUTHWEST FLOW.
