THIS HAZARDOUS WEATHER OUTLOOK IS FOR CENTRAL AND NORTHEAST OREGON
AS WELL AS SOUTH CENTRAL AND SOUTHEAST WASHINGTON.

.DAY ONE...TODAY AND TONIGHT

THE PROBABILITY FOR WIDESPREAD HAZARDOUS WEATHER IS LOW.

A STRONG UPPER LEVEL HIGH PRESSURE RIDGE ALONG THE COAST THIS
MORNING WILL MOVE EAST THROUGH THE DAY WITH THE RIDGE AXIS MOVING
OVER EASTERN WASHINGTON/OREGON BY THIS AFTERNOON. THE HIGH PRESSURE
WILL PROVIDE A DRY SOUTHERLY FLOW ALOFT TODAY FOR MOSTLY SUNNY SKIES
AND WARMER HIGH TEMPERATURES THIS AFTERNOON. THE RIDGE WILL CONTINUE
OVER THE PACIFIC NORTHWEST TONIGHT FOR A CONTINUATION OF DRY
CONDITIONS.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

THE PROBABILITY FOR WIDESPREAD HAZARDOUS WEATHER IS LOW.

THE AFOREMENTIONED UPPER LEVEL RIDGE STARTS BREAKING DOWN ON FRIDAY
AS THE RIDGE AXIS MOVES EAST INTO IDAHO/MONTANA. AS SUCH THE RIDGE
WILL BRING DRY CONDITIONS AND WARMER TEMPERATURES THROUGH FRIDAY. A
WEAKENING AND MAINLY DRY FRONTAL BOUNDARY MOVES ACROSS THE REGION
FRIDAY NIGHT. THE EAST SLOPES OF THE CASCADES WILL HAVE THE BEST
CHANCE FOR PRECIPITATION WITH THIS SYSTEM DURING FRIDAY NIGHT.

WASHINGTON AND OREGON WILL BE UNDER A SOUTHWEST FLOW ALOFT SATURDAY
AS THE NEXT SYSTEM APPROACHES THE COAST WITH THE BEST CHANCE FOR
PRECIPITATION OVER THE CASCADES. A STRONG WEATHER SYSTEM WILL PUSH A
COLD FRONT AND ATTENDANT MOISTURE THROUGH THE FORECAST AREA SATURDAY
NIGHT AND SUNDAY FOR RAIN AND SNOW LIKELY IN THE MOUNTAINS WITH A
CHANCE OF RAIN IN THE COLUMBIA BASIN AND ADJACENT VALLEYS AS WELL AS
IN NORTH CENTRAL OREGON. THEN A SERIES OF STRONGER UPPER LEVEL
TROUGHS AND ASSOCIATED SURFACE FRONTS MOVE ACROSS THE AREA MONDAY
THROUGH THE MIDDLE OF NEXT WEEK. THESE SYSTEMS WILL BRING RAIN AND
MOUNTAIN SNOW ALONG WITH COOLER TEMPERATURES.
