NOAA is forecasting an insane amount of precipitation for Washington in the next week.
17-23 inches of liquid precipitation if forecast to fall on Washington in the next 7 days. If that all came as snow, that would translate to 15-23 feet of snow.
Snow levels will be fluctuating with these storms. Snow levels are forecast to get higher with each successive storm this week until topping out around 8,000-feet Tuesday. Snow levels are forecast to drop back down to 2,000-3,500 feet on Wednesday and remain there while 2 or 3 storms roll through Wed – Sat (see graphs & info below). Mt. Baker ski area lives between 3,000 and 5,000 feet. Crystal Mountain ski area lives between 4,400 and 7,000 feet.
The upper mountain of 10-781′ Mt. Baker is forecast to see 88-119″ of snow in the next 3 days.
Snow levels are forecast to get higher with each successive system until Tuesday. On Wednesday snow levels are forecast to drop back down to the 2,000-3,500 foot range while 2 or 3 storms roll through Washington Wednesday to Saturady.
SNOW LEVELS - EACH INCOMING SYSTEM BRINGS YET WARMER AIR. FLOW IN THE PASSES TO BRIEFLY GO WEST AND MODERATE TEMPS THERE TODAY BEFORE SWINGING BACK TO EAST LATE TODAY. YET THE TREND IS FOR HIGHER SNOW LEVELS WITH EACH SYSTEM INTO TUESDAY...CLIMBING FROM 4000 TO 5000 FT TODAY TO 5000 TO 7000 FT MONDAY AND PERHAPS AS HIGH AS 8000 FT TUESDAY. - NOAA Seattle, WA today.LONG TERM...FROM THE PREVIOUS DISCUSSION...IT LOOKS LIKE THERE WILL BE A TRANSITION TO A COOLER PATTERN AROUND WEDNESDAY OR WEDNESDAY NIGHT...BUT RECENT MODEL RUNS OF THE GFS...EUROPEAN...AND CANADIAN MODELS KEEP THE PATTERN FAIRLY ACTIVE WITH TWO OR THREE SYSTEMS MOVING THROUGH BETWEEN WEDNESDAY AND SATURDAY. THERE IS A GOOD CHANCE THE SNOW LEVEL WILL BE MAINLY IN THE 2000 TO 3500 FT RANGE DURING THIS PERIOD. - NOAA Seattle, WA today
