REGIONAL SATELLITE AND RADAR SHOWED CIRRUS OVERSPREADING THE
OREGON CASCADES INTO CENTRAL OREGON. A STABLE LAYER IMPINGING ON
THE UPPER CASCADE CREST OF WASHINGTON WAS STILL ALLOWING HIGH
ELEVATIONS SNOW IN KITTITAS COUNTY, WHERE THE HREF CONTINUED TO
HINT AT LIGHT SNOW ACCUMULATIONS. ROAD CAMS AND MESONET
OBSERVATIONS INDICATED REDUCED VISIBILITY TO UNDER 1 MILES IN
THE UPPER SLOPES IN KITTITAS COUNTY, BUT NO DISCERNIBLE IMPACTS
AS THE ROADS WERE ALL WET THOUGH THE PASS LEVEL. SOME OF THAT
DOWNSLOPING ADIABATIC WARMING WILL BE LOST BY SATURDAY AS WINDS
SLACK OFF OVER MUCH OF THE ENTIRE REGION. SUNNY AND SPRING LIKE
50S’ WILL MAKE A PLEASANT WEEKEND, WHILE MOUNTAIN SLOPES AND
HIGHER ELEVATIONS ARE RELEGATED TO THE 40S.
SURFACE WIND GUSTS BOTH THIS AFTERNOON AND FRIDAY WILL REMAIN
BREEZY/GUSTY WITH THE 75TH PERCENTILE OF THE NBM WIND GUST IN
THE FALLING IN THE 30+ MPH RANGE. THE WEST TO SOUTHWESTERLY
FLOW EAST OF THE CASCADES WILL LEAD TO A WARMING TEMPERATURES IN
THE AFTERNOON FRIDAY AS HIGHS APPROACH 60 DEGREES ACROSS THE
LOWER COLUMBIA BASIN. THE NEXT APPRECIABLE CHANCES FOR
PRECIPITATION RETURN ACROSS THE CENTRAL OREGON CASCADE SLOPES
THIS WEEKEND WITH PROFILES SUPPORTING RAIN OR RAIN/SNOW IN THOSE
ZONES, BEFORE DRYING OUT REGION WIDE FOR MONDAY AND TUESDAY.
HIGH PROBABILITIES FOR RAIN OR SNOW, (70-90%) RETURN BY EARLY
WEDNESDAY, DEPENDING ON ELEVATION LEVELS ACROSS THE HIGHER
TERRAIN.
AVIATION /00Z TAFS THROUGH 00Z SATURDAY/
VFR CONDITIONS WILL CONTINUE PREVAILING FOR ALL SITES. LATEST
GUIDANCE STILL DEPICTS SOUTHWEST SUSTAINED WINDS FOR KPDT/KPSC
AND NORTHWEST WINDS FOR KDLS AROUND 12-15KTS THIS AFTERNOON INTO
EARLY EVENING. KDLS/KPSC ARE CURRENTLY GUSTING AT 20-25KTS AND
MAY CONTINUE THROUGH 03Z, WITH A 30-40% PROBABILITY ON THE
TIMING/EXTENT. WINDS FOR THOSE SITES SHOULD DECREASE DURING THE
EVENING HOURS. HOWEVER, KPDT/KALW MIGHT HAVE SUSTAINED WINDS OF
12-15KTS AROUND 17-18Z FRIDAY MORNING, BUT CONFIDENCE IS LOW
(15-30%). FEASTER/97
