SYNOPSIS
A WETTER, MORE ACTIVE PATTERN ARRIVES SATURDAY AFTERNOON
BRINGING WIDESPREAD RAIN AND MOUNTAIN SNOW THROUGH MONDAY. DRY
WEATHER RETURNS TUESDAY AND WEDNESDAY, THEN ANOTHER SYSTEM MOVES
IN TOWARD THE END OF THE WEEK.
DISCUSSION
TODAY THROUGH MONDAY: A PLUME OF MOISTURE CAN BE SEEN ON SATELLITE
STREAMING IN FROM THE SOUTHWEST WITH RADAR SHOWING RAIN BEGINNING TO
SPREAD EAST OF THE CASCADES. SNOW LEVELS WILL REMAIN AT 5K TO 6K
FEET THROUGH TONIGHT, KEEPING PRECIP IN THE FORM OF RAIN OVER
MOUNTAIN PASSES. HEADING INTO SUNDAY, SNOW LEVELS WILL FALL TO
AROUND 3K FEET, BRINGING A TRANSITION TO SNOW AT PASS LEVELS. SNOW
LEVELS WILL DROP FURTHER BY MONDAY, FALLING TO 2.5K FEET. FOR
LOOKOUT PASS, LATEST RUNS OF THE NBM GIVE LOOKOUT PASS AN 80% CHANCE
OF SEEING AT LEAST 2 INCHES OF SNOW BY MONDAY EVENING (UP FROM 75%
IN PREVIOUS RUNS) AND A 15% CHANCE OF 6 OR MORE INCHES OF SNOW (DOWN
FROM 25% IN PREVIOUS RUNS). FOR STEVENS PASS, THERE IS A 20% CHANCE
OF 2 OR MORE INCHES OF SNOW AND A 10% CHANCE OF 6 OR MORE INCHES. IN
ADDITION TO RAIN AND SNOW, THIS SYSTEM WILL BRING BREEZY WINDS
TONIGHT AND AGAIN SUNDAY NIGHT INTO MONDAY ACROSS THE COLUMBIA
BASIN, NORTH ID, AND INTO THE SPOKANE/CDA AREA WITH GUSTS OF 20 TO
30 MPH. AFTERNOON HIGH TEMPERATURES DURING THIS PERIOD WILL RANGE
FROM THE UPPER 30S IN THE NORTHERN VALLEYS TO UPPER 40S FOR THE
DEEPER COLUMBIA BASIN AND IN THE L-C VALLEY. CLOUDS AND MOISTURE
WILL KEEP DIURNAL RANGES SMALL WITH OVERNIGHT LOWS IN THE MID 30S TO
LOW 40S.
TUESDAY AND WEDNESDAY: THE INLAND NORTHWEST WILL SHIFT INTO A SPLIT
FLOW PATTERN WITH SYSTEMS MOVING BY TO OUR NORTH AND SOUTH. WHILE
BRITISH COLUMBIA AND CALIFORNIA ARE GETTING ACTIVE WEATHER WITH
THESE SYSTEMS, WE WILL STAY DRY. AFTERNOON HIGHS WILL HOLD STEADY IN
THE UPPER 30S TO UPPER 40S, BUT THE ARRIVAL OF DRIER AIR WILL RESULT
IN LARGER DIURNAL TEMPERATURE RANGES WITH OVERNIGHT LOWS FALLING
INTO THE MID 20S TO LOW 30S.
THURSDAY AND FRIDAY: OUR NEXT SYSTEM APPROACHES THURSDAY EVENING
BRINGING LIGHT MOUNTAIN SNOW AND A MIX OF RAIN AND SNOW FOR THE
VALLEYS. ENSEMBLES HAVE COME INTO BETTER AGREEMENT ON THE STRONGEST
DYNAMICS DIVING TO OUR SOUTH WITH ONLY 13% OF ENSEMBLE MEMBERS
BRINGING THE BULK OF THE DYNAMICS DIRECTLY OVER THE INLAND
NORTHWEST. IF THE STRONGER DYNAMICS WERE TO MOVE OVER THE REGION
WE'D BE LOOKING AT HIGHER PRECIP AMOUNTS, BUT RIGHT NOW THAT DOES
NOT LOOK LIKELY.
LOOKING AHEAD TO MID-FEBRUARY, THE CLIMATE PREDICTION CENTER'S 8-14
DAY OUTLOOK PLACES THE CASCADES IN AN AREA OF SLIGHT RISK FOR HEAVY
SNOW FROM FEBRUARY 15TH THROUGH 21ST. PERHAPS NOT ALL HOPE IS LOST
FOR GETTING SOME SNOW IN THE MOUNTAINS THIS WINTER? WE'LL SEE IF
THIS SNOW SIGNAL PERSISTS OVER THE COMING DAYS. /FEWKES
