NATIONAL WEATHER SERVICE PENDLETON OR
225 PM PST SAT DEC 1 2001
STRONG SOUTH WINDS CONTINUE THIS AFTERNOON ACROSS THE NORTHEAST
CORNER OF OREGON AND THE SOUTHEAST WASHINGTON BLUES. THIS TREND WILL
CONTINUE THIS EVENING AS THE PRESSURE GRADIENT REMAINS RELATIVELY
STRONG...AND THERE IS A 50KT 850MB JET AND SOME INSTABILITY MOVING
OVER NORTHEAST OREGON/SOUTHEAST WASHINGTON THROUGH 06Z. WILL
THEREFORE KEEP THE HIGH WIND WARNING GOING UNTIL MIDNIGHT. A
NORTHERLY FLOW WILL SET UP OVERNIGHT BRINGING COOLER UNSTABLE AIR
OVER THE FORECAST AREA. THIS FLOW MAY KEEP ISOLATED LIGHT RAIN/SNOW
SHOWERS OVER FORECAST AREA OVERNIGHT...AND WILL HELP SET AN
INTERESTING STAGE FOR THE NEXT SYSTEM MOVING THROUGH SUNDAY NIGHT
AND MONDAY. THIS NEXT SYSTEM IS CURRENTLY OUT AT 40N/140W AND WILL
MOVE INTO SOUTHERN OREGON DURING THE DAY SUNDAY...SPREADING
RAIN/SNOW INTO THE SOUTHERN ZONES AND THE BLUE MOUNTAINS. THE
SURFACE LOW IS EXPECTED TO HAVE A VERY FAVORABLE TRACK FOR SNOW
PRODUCTION ALONG THE MOUNTAINS OF CENTRAL OREGON AND THE BLUE
MOUNTAINS SUNDAY NIGHT AND MONDAY. THE GLITCH IS THE QPF AMOUNTS ARE
MARGINAL. THE RAIN/SNOW IS EXPECTED TO MOVE ACROSS THE ENTIRE
PENDLETON FORECAST AREA OVERNIGHT SUNDAY AND TAPER OFF TO SHOWERS
FROM WEST TO EAST MONDAY AFTERNOON. WILL HAVE TO KEEP AN EYE ON THE
WATER VAPOR TO SEE IF MORE MOISTURE MOVES IN WITH THIS NEXT SYSTEM.
ANOTHER FACTOR TO WATCH WILL BE HOW MUCH COOL AIR WILL GET FILTERED
INTO THE BASIN. THIS WILL DETERMINE PRECIPITATION TYPE. WILL ADD
MENTION OF BOTH AT THIS TIME AND WAIT FOR LATER RUNS FOR
CLARIFICATION. AVN SEEMS TO HAVE A MUCH BETTER HANDLE ON NEXT
SYSTEM...AND ALSO INITIALIZED BETTER WITH CURRENT SYSTEM. GUIDANCE
TEMPERATURE SEEM REASONABLE SO FOLLOWED THEIR TREND. MEAD
IN THE EXTENDED...A RATHER ACTIVE PATTERN THOUGHOUT THE EXTENDED.
