CURRENT SATELLITE SHOW LOW AND MID LEVEL CLOUDS FORMING ACROSS THE
EASTERN SLOPES OF THE CASCADES AND THROUGH PORTIONS OF CENTRAL OR.
RADAR SHOWS NOT RETURNS ACROSS MUCH OF THE REGION. HOWEVER, BEND AND
REDMOND OBSERVATIONS ARE CURRENTLY REPORTING LIGHT SNOW. THIS WILL
LIKELY CONTINUE OVER THE NEXT FEW HOURS WITH UP TO 0.10 INCHES OF
ADDITIONAL SNOW ACCUMULATION (70-90%).
MODELS SHOW THE UPPER LEVEL LOW TO BE TO THE SOUTHWEST OF THE REGION
BRINGING IN A SLIGHT SOUTHWEST FLOW AND LIGHT PRECIPITATION THROUGH
THE REMAINDER OF THE DAY TODAY. MOUNTAINS WILL CONTINUE TO SEE LIGHT
SNOW SHOWERS (80-90%) WITH ACCUMULATIONS NEARING 0.10-0.30" FOR THE
WA CASCADES, 0.20-0.50 FOR THE OCHOCO-JOHN DAY HIGHLANDS (60-80%)
AND 0.30-0.40" FOR THE NORTHERN BLUES (70-90%)
AS WE MOVE INTO FRIDAY, MODELS SHOW THE LEADING EDGE OF A WEAK UPPER
LEVEL RIDGE WILL MAKE ITS WAY INTO THE REGION BRINGING WITH IT LIGHT
PRECIPITATION MAINLY TO THE HIGH PEAKS OF THE CASCADES AND A BIT
MORE PRECIPITATION CAUSED BY OROGRAPHIC LIFTING TO THE NORTHERN
BLUES. WITH THAT, MODELS AS WELL AS HREF RAW ENSEMBLES SHOW 70-90%
PROBABILITIES OF THE NORTHERN BLUES, MEACHAM, TOLLGATE ANS BLUEWOOD
SEEING AN ADDITIONAL 1-2" OF SNOW FRIDAY WITH THE SLOPES OF THE
NORTHERN BLUES SEEING 0.2-0.3 INCHES. AS FOR THE EAGLE CAPS AND THE
SURROUNDING WALLOWA MOUNTAINS, HREF RAW ENSEMBLES HAVE THE RIDGETOPS
SEEING 1-2" (70-90%) WHILE PORTIONS OF WALLA VALLEY COULD SEE 0.20-
0.3" (30-50%). LASTLY, UNION COUNTY COULD SEE LIGHT SNOW OF 0.10-
0.20" (60-80%).
WITH THE INCOMING FRONTAL SYSTEM, BOTH THE NBM AND HREF ARE PICKING
UP ON AN INCREASE IN WINDS ACROSS THE FOOTHILLS OF THE SOUTHERN AND
NORTHERN BLUES, THROUGH UNION COUNTY AND PORTIONS OF CENTRAL OR ON
SATURDAY MORNING. HREF RAW ENSEMBLES SHOW WINDS TO KICK UP AFTER 4
AM WITH 70-80% PROBABILITIES OF THE FOOTHILLS OF THE BLUES AND
ISOLATED LOCATIONS THROUGH CENTRAL OR SEEING WINDS NEARING 20 MPH
SUSTAINED WITH GUSTS TO 30 MPH. AFTER NOON, NBM RAW ENSEMBLES PICK
UP ON WINDS INCREASING THROUGH UNION COUNTY WITH 80-90%
PROBABILITIES OF SUSTAINED WINDS NEARING 30 MPH WITH GUSTS TO NEAR
40 MPH. ALTHOUGH MODELS ARE NOT PICKING UP ON IT, PATTERN
RECOGNITION WITH SOUTHERLY FLOW OVER THE MOUNTAINS INTO WALLOWA, WE
EXPECT WINDS TO INCREASE THROUGH THE VALLEY.
MODELS SHOW AN ACTIVE PATTERN TO PERSIST THROUGH THE LONG TERM. THIS
PATTERN WILL BRING MOUNTAIN SNOW AND LOW ELEVATION RAIN. CLUSTERS
SHOW THE MAIN DEVIATION WITH THE MODELS IS IN THE TIMING AND OR
LOCATION OF THE INCOMING SYSTEMS. REGARDLESS, ALL MODELS SHOW
PRECIPITATION ACCOMPANYING THE NEXT ROUND OF SYSTEMS. (50-70%
