..COOLER THAN NORMAL THROUGH THE PERIOD
..SHOWERS FOR AREAS NEAR AND NORTH OF I-80 THROUGH SUNDAY
METEOROLOGICAL CONDITIONS (FRI AM - THU AM)
GENERAL TROFFING ACROSS THE WEST COAST IS BEING REINFORCED BY AN
AREA OF LOW PRESSURE MOVING OUT OF THE GULF OF ALASKA TOWARD THE
SOUTHEAST. THIS IS CURRENTLY GENERATING SCATTERED SHOWERS ACROSS
AREAS NEAR AND NORTH OF I-80 THIS MORNING. AS THE SYSTEM FROM THE
NORTHWEST SETTLES ACROSS THE WESTERN US THIS WEEKEND...LOOK FOR
BROAD TROFFING ACROSS THE REGION WITH COOLER THAN NORMAL
TEMPERATURES BOTTOMING OUT EITHER SATURDAY OR SUNDAY FROM WEST TO
EAST ACROSS THE AREA. AFTERNOON TEMPERATURE ANOMALIES COULD RUN
ANYWHERE FROM 5- TO 25-DEGF UNDER SEASONAL NORMALS. ALSO...THROUGH
THE WEEKEND...EXPECT ROUNDS OF SHOWERS TO MOVE ACROSS THE REGION
WITH INDIVIDUAL DISTURBANCES ROTATING THROUGH THE GENERAL FLOW WITH
THE BEST CHANCE OF PRECIP REMAINING NEAR AND NORTH OF I-80.
THE TROFFING ACROSS THE WESTERN US WILL REMAIN IN PLACE THROUGH THE
MIDDLE OF NEXT WEEK...WEAKENING A BIT. THIS SHOULD BRING AN END TO
THE PRECIP CHANCES...BUT COOLER THAN NORMAL TEMPERATURES ARE
ANTICIPATED TO LAST ALL THE WAY THROUGH THE WEEK.
FREEZING LEVELS ARE CURRENTLY RUNNING FROM 10000- TO 16000-FEET
ACROSS THE REGION...LOWEST NORTHWEST AND HIGHEST SOUTHEAST. AS THE
COOLER AIR FILTERS IN ACROSS MUCH OF THE REGION...LOOK FOR FREEZING
LEVELS TO BOTTOM OUT LATE SATURDAY OR EARLY SUNDAY FROM 6500-FEET
OVER THE UPPER KLAMATH RIVER BASIN...NORTHEAST CA...AND NORTHWEST
NV. FOR SOUTHERN AREAS...WHERE COOLER AIR DOESN/T QUITE
REACH...FREEZING LEVELS SHOULD REMAIN NEAR OR JUST ABOVE 16000-FEET.
WITH SLIGHT WEAKENING TO THE CYCLONIC FLOW ACROSS THE WEST DURING
THE MIDDLE OF NEXT WEEK...LOOK FOR FREEZING LEVELS TO REACH UP
CLOSER TO 12000-FEET OVER THE UPPER KLAMATH RIVER BASIN TO ABOUT
16000-FEET NEAR THE CA/MX BORDER.
