NORTHWEST OREGON AND SOUTHWEST WASHINGTON FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PORTLAND OR
900 AM PDT THU JUL 29 1999

SYSTEM MOVING THROUGH CANADA HAS BROUGHT A MARINE PUSH TO SOUTHWEST
WASHINGTON AND NORTHWEST OREGON. THIS WILL BRING COOLER TEMPERATURES
CLOSER TO SEASONAL NORMS. EXPECT SUNSHINE TO BREAK OUT THIS AFTERNOON
THOUGH CLOUDS MAY PERSIST NEAR THE COASTLINE IN THE AFTERNOON. UPPER
LOW OFF CALIFORNIA COAST SEEMS FAR ENOUGH EAST THAT MOISTURE AND
DYNAMIC EFFECTS ON FORECAST AREA WILL BE MINOR FOR AWHILE. EXPECT
MARINE CLOUDINESS TO COME BACK ONSHORE AND INLAND TONIGHT AND FRIDAY
...THOUGH A LITTLE EARLIER BURNOFF FRIDAY. NO MARINE ADVISORIES AS
GRADIENTS RELATIVELY WEAK. EXTENDED MODELS SHOW UPPER LOW OFF THE
CALIFORNIA COAST MOVING CLOSER TO THE COAST AND ALSO NORTHWARD THIS
WEEKEND FOR BETTER CHANCE OF INLAND CONVECTION. CURRENT FORECAST
PACKAGE LOOKS REASONABLE. TOLLESON
