FEET OVER THE WASHINGTON CASCADES TO NEAR 4000 FEET OVER THE

UPSLOPE FLOW WILL DEVELOP OVER THE EAST SLOPES OF THE CASCADES TODAY
AND WILL AID IN ENHANCING PRECIPITATION AMOUNTS THERE. THE UPPER
LOW WILL SLOWLY MOVE OVER WASHINGTON TONIGHT AND PRODUCE UPSLOPE
FLOW OVER THE BLUE MOUNTAINS. GIVEN THE SLOW MOVEMENT OF THIS
SYSTEM...SNOW TOTALS WILL LIKELY REACH WARNING CRITERIA BY SUNDAY
OVER THE BLUE MOUNTAINS. WITH THE TRACK OF THE UPPER LOW REMAINING
FARTHER WEST AND PRIMARILY OVER WASHINGTON...BELIEVE WALLOWA COUNTY
WILL ESCAPE THE THREAT OF HEAVY SNOW THIS TIME AROUND. THEREFORE...
