SHORT TERM...TODAY THROUGH TUESDAY...THE REGION WILL REMAIN UNDER A SOUTHWEST FLOW BETWEEN AN UPPER RIDGE OVER THE GREAT BASIN AND AN UPPER TROUGH OFFSHORE THROUGH TUESDAY. WEAK DISTURBANCES WILL BRING SOME SPOTTY PRECIP TO PORTIONS OF THE AREA TODAY. PRECIP CHANCES WILL INCREASE FROM WEST TO EAST LATE TONIGHT INTO TUESDAY AS A STRONGER WAVE WORKS ONSHORE AND FLATTENS THE UPPER RIDGE. SNOW LEVELS WILL REMAIN HIGH THROUGH THIS PERIOD. WINDS WILL BE GENERALLY LIGHT ACROSS THE COLUMBIA BASIN AND SURROUNDING AREAS. SOUTH WINDS WILL GRADUALLY INCREASE ACROSS THE HIGHER TERRAIN AND IN THE GRANDE RONDE VALLEY. AREAS OF DENSE FOG CONTINUE OVER THE BLUE MOUNTAIN FOOTHILLS, NORTH-CENTRAL OREGON, THE SIMCOE HIGHLANDS, THE KITTITAS VALLEY, AND SOME VALLEYS IN THE WASHINGTON CASCADE EAST SLOPES. THUS WILL CONTINUE THE CURRENT DENSE FOG ADVISORIES. FOG HAS PUSHED INTO THE REDMOND, BEND AND PRINEVILLE AREAS. TEMPS ARE AROUND FREEZING, THUS WILL ISSUE A FREEZING FOG ADVISORY FOR THE CENTRAL OREGON ZONE. PATCHY FOG CONTINUES OVER LOWER PORTIONS OF THE COLUMBIA BASIN AND THE GORGE, BUT IS NOT WIDESPREAD ENOUGH FOR ADVISORIES AT THIS TIME. HIGH TEMPS WILL BE SEASONALLY MILD ABOVE 3500 FEET, BUT WILL REMAIN COOL IN THE FOGGY AREAS
