KEY MESSAGES
* EPISODES OF LIGHT RAIN AND HIGH ELEVATION SNOW TO CONTINUE
THROUGH THE WEEKEND.
* UNSETTLED WEATHER WILL PERSIST ACROSS THE WESTERN U.S. THROUGH
THE WEEK WITH PERIODS OF BREEZY CONDITIONS AND ADDITIONAL ROUNDS
OF LIGHT RAIN AND MOUNTAIN SNOW.
DISCUSSION
AN UNSETTLED PATTERN REMAINS ANCHORED ACROSS THE WESTERN U.S. AS
A LARGE UPPER TROUGH CONTINUES TO LINGER OFF THE PACIFIC COAST.
SMALLER SCALE IMPULSES WITHIN THE FLOW WILL CONTINUE TO PROMOTE
EPISODES OF RAIN AND MOUNTAIN SNOW THROUGH TONIGHT. A BIT OF A
RESPITE IS THEN EXPECTED BEFORE ANOTHER ROUND OF RAIN AND MOUNTAIN
SNOW LATE SATURDAY INTO SUNDAY. AT THIS TIME, PRECIPITATION
AMOUNTS APPEAR QUITE MODEST, WITH PROBABILITIES OF A TENTH OF AN
INCH OF RAIN HOVERING AROUND 10-20 PERCENT IN THE LOWER ELEVATIONS
AND THE HEAVIER TOTALS CONFINED TO ELEVATIONS ABOVE 5000 FT.
FOR THE COMING WORK WEEK, THE GENERAL PATTERN APPEARS QUITE
STEADY. THE UPPER TROUGH WILL GRADUALLY MIGRATE EASTWARD, WITH
ADDITIONAL ROUNDS OF LIGHT PRECIPITATION. TOWARD THE LATTER HALF
OF THE WEEK, ENSEMBLES POINT TO A MORE PRONOUNCED STORM SYSTEM
DIGGING FROM THE PACIFIC NORTHWEST SOUTHWARD, WHICH COULD INDUCE A
PERIOD OF BREEZY/WINDY AND COLDER CONDITIONS, HOWEVER CONFIDENCE
ON THE EXACT PLACEMENT AND INTENSITY OF THIS SYSTEM REMAINS QUITE
LOW. HEADING INTO NEXT WEEKEND, ENSEMBLE SOLUTIONS POINT THE
DEVELOPMENT OF A PRONOUNCED UPPER RIDGE ALONG THE WEST COAST WITH
PERSISTENT NORTH/NORTHWEST FLOW, WHICH MAY RESULT IN SUSTAINED
COOLER TEMPERATURES BEFORE A GRADUAL REBOUND.

WHICH SHOULD ALSO PERSIST THROUGH THE REMAINDER OF THE EVENING AND

VISIBILITIES DOWN TO AROUND 3-5SM FOR MUCH OF THE OVERNIGHT PERIOD;
HOWEVER, A FEW AREAS COULD SEE VISIBILITIES DROP TO LESS THAN 3SM AT

IS EXPECTED BY AFTERNOON. LIGHT WINDS WILL PERSIST THROUGH FRIDAY.
