NORTHEAST OREGON/SOUTHEAST WASHINGTON FORECAST DISCUSSION NATIONAL WEATHER SERVICE PENDLETON OR 230 PM PST SAT JAN 13 2001 A SERIES OF WEATHER DISTURBANCES IN A NORTHWEST FLOW ALOFT WILL MOVE THROUGH THE FORECAST AREA DURING THE NEXT 24 TO 36 HOURS. THE FIRST HAS ALREADY BROUGHT SOME RAIN AND HIGHER ELEVATION SNOW TO THE AREA TODAY. THIS FIRST BAND OF RAIN AND SNOW HAS MOVED NORTHEAST INTO SOUTHEAST WASHINGTON. THE NEXT BAND IS ABOUT TO MOVE THROUGH THE FOOTHILLS OF THE BLUE MOUNTAINS LATER THIS AFTERNOON AND THIS EVENING AND THEN INTO THE NORTHEAST OREGON AND SOUTHEAST WASHINGTON MOUNTAINS OVERNIGHT. TEMPERATURES WILL DROP TO AROUND FREEZING WITH COOLING ALOFT IN THE COLUMBIA BASIN AND FOOTHILLS. BELIEVE THERE WILL BE ENOUGH SNOW IN THE HIGHER ELEVATIONS OF THE BLUE MOUNTAIN FOOTHILLS TO WARRANT CONTINUING THE SNOW ADVISORY THAT WAS ISSUED EARLIER TODAY. THEN THE NEXT WEATHER DISTURBANCE IN THE UPPER FLOW WILL DROP DOWN FROM BRITISH COLUMBIA ON SUNDAY BRINGING ANOTHER WAVE OF MOISTURE. BY THIS TIME 850 MB TEMPERATURES WILL HAVE COOLED TO AROUND -5 TO -6 DEGREES C. SO MOST OF THE PRECIPITATION WILL BE IN THE FORM OF SNOW EXCEPT IN THE LOWEST ELEVATIONS OF THE FORECAST AREA. THIS SECOND SYSTEM LOOKS A LITTLE STRONGER WITH BETTER OMEGA (LIFT) THAN THE CURRENT ONE. BY SUNDAY NIGHT THESE SYSTEMS MOVE EAST AS THE UPPER TROUGH FINALLY SHIFTS EASTWARD. THEN AN UPPER RIDGE WILL AMPLIFY ALONG THE COAST ON MONDAY BRINGING A DRIER NORTHERLY FLOW TO THE AREA. AS CONDITIONS ALOFT BEGIN TO DRY OUT AND SKIES CLEAR... AREAS OF LOW CLOUDS AND FOG WILL BECOME A PROBLEM IN THE VALLEYS AND BASINS WITH THE ABUNDANT LOW LEVEL MOISTURE FROM PREVIOUS RAIN AND SNOWFALL. WILL KEEP TEMPERATURES ON THE COOL SIDE...A FEW DEGREES COOLER THAN GUIDANCE FOR MONDAY AS A RESULT. RSC. EXTENDED...EXPECT LOWER CLOUDS AND AREAS OF FOG TO PERSIST TUESDAY THROUGH THURSDAY OVER THE VALLEYS AND COLUMBIA BASIN AS AN UPPER LEVEL RIDGE CAMPS OUT OVER THE PACIFIC NORTHWEST. THIS WILL STRENGTHEN INVERSIONS THROUGHOUT THE COLUMBIA BASIN AND LOWER VALLEYS WHILE THE MOUNTAINS ENJOY MOSTLY SUNNY SKIES UNDER THE UPPER RIDGE. THEN THE EXTENDED PERIOD MODELS START TO DIFFER FRIDAY IN TIMING THE EASTWARD MOVEMENT OF A TROUGH AND ASSOCIATED DISTURBANCE. WILL GO WITH A CHANCE OF PRECIPITATION THROUGHOUT OUR AREA FRIDAY AND SATURDAY...AS THE RIDGE AND TROUGH SHOULD TBOTH SHIFT EAST DURING THAT TIME FRAME.
