DISCUSSION
FRIDAY AND SATURDAY: THE AIR MASS IN PLACE IS REGISTERING OVER
200% OF NORMAL ON THE PRECIPITABLE WATER READINGS WITH THE
PLUME OF MOISTURE AIMED AT THE INLAND NORTHWEST. THIS PLUME WILL
MAINTAIN A MILD AND WET PATTERN THROUGH FRIDAY WITH THE UPPER
LEVEL TROUGH TO THE NORTH SWINGING OVERHEAD ACROSS THE
NORTHWEST. THE SURFACE LOW POSITIONED IN ALBERTA ALONG WITH THE
FLATTENING OF THE TROUGH TO A MORE ZONAL WEST TO EAST FLOW WILL
RESULT IN BREEZY WEST- SOUTHWEST WINDS FRIDAY ACROSS THE SOUTH-
CENTRAL WASHINGTON BASIN, THE WEST PLAINS, AND UP THROUGH THE
OKANOGAN VALLEY. WINDS WILL REMAIN ELEVATED INTO SATURDAY. A
BRIEF TRANSITION FRIDAY EVENING WITH THE AIR MASS SEEING A BRIEF
DRYING TREND BEFORE ANOTHER PLUME OF MOISTURE RELOADS FOR
SATURDAY, AIMED MORE AT THE HIGHER ELEVATIONS. SNOW LEVELS WILL
RISE FRIDAY NIGHT FROM 5000 FEET TO WELL OVER 7000-8000 FEET BY
SATURDAY NIGHT. SNOW ACCUMULATIONS AT WASHINGTON PASS HAVE
CONTINUED TO DECREASE, HOWEVER TOTALS THROUGH SATURDAY MORNING
SHOULD END UP BETWEEN 5-8 INCHES (30% CHANCE FOR MORE THAN 6
INCHES).
SUNDAY THROUGH THURSDAY: THE NEXT WEATHER SYSTEM WILL BEGIN TO
ENTER THE REGION SUNDAY EVENING WITH ANOTHER PLUME OF MOISTURE
AND A COLDER AIR MASS. SNOW LEVELS WILL RAPIDLY LOWER BY MONDAY
EVENING TO 3000 - 4000 FEET INTO TUESDAY. THE PRECIPITATION
CHANCES ALSO DECREASE WITH THE COLDER TEMPERATURES AND THE LOSS
OF HIGHER PRECIPITABLE WATER VALUES. LIGHT PRECIP CHANCES
THROUGH WEDNESDAY WILL RETURN WITH THE HIGHER FOCUS ON THE
DISTURBANCE LATE IN THE WEEK BRINGING ANOTHER ROUND OF
PRECIPITATION WITH LOWER SNOW LEVELS AND COLDER TEMPERATURES
(NEAR FREEZING) AND THE CHANCE FOR A RAIN-SNOW MIX DOWN TO
VALLEYS. CONFIDENCE IS NOT GREAT IN THIS SOLUTION, BUT THE CPC
8-14 DAY HAZARDS DOES PAINT MESSAGE OF SLIGHT RISK (20-40%
CHANCE) CHANCE OF BELOW NORMAL TEMPERATURES COINCIDENT WITH A
SLIGHT RISK (20-40%) CHANCE OF SNOW BY LATE NEXT WEEK. SOMETHING
TO KEEP OUR EYES ON. /DEWEY
