A COLD FRONT WILL STALL OVER WESTERN WASHINGTON WEDNESDAY NIGHT AND REMAIN IN PLACE INTO THURSDAY NIGHT GENERATING PERIODS OF RAIN ACROSS THE REGION. A SURFACE LOW PRESSURE CENTER IS EXPECTED TO DEVELOP ALONG THE FRONT WELL WEST OF OREGON THEN MOVE UP THE FRONT AND ACROSS THE NORTHWEST EARLY FRIDAY. THIS LOW WILL GENERATE ANOTHER PERIOD OF HEAVIER RAIN ACROSS PARTS OF WESTERN WASHINGTON. THROUGH THIS PERIOD...FREEZING LEVELS WILL REMAIN HIGH ENOUGH FOR MOSTLY RAIN ACROSS THE MOUNTAINS. WHERE THE AREAS OF HEAVIER RAIN OCCUR WILL DEPEND UPON ON WHERE THE FRONT STALLS AND THE EXACT PATH OF THE LOW THAT IS EXPECTED TO MOVE UP THE FRONT. A NORTH OR SOUTH SHIFT OF EITHER WILL MAKE A SIGNIFICANT DIFFERENCE ON WHICH AREA RECEIVES THE HEAVIER RAINS. UNDER MORE NORMAL CIRCUMSTANCES...THE AMOUNT OF RAIN FORECAST WOULD GENERALLY NOT POSE THIS MUCH OF A PROBLEM...BUT RIVERS ARE STILL DRAINING WATER FROM THE RECENT RAINS AND COULD RESPOND MORE READILY TO ADDITIONAL RAINFALL. AT THIS TIME...RIVERS OF CONCERN INCLUDE THE SKOKOMISH ON THE OLYMPIC PENINSULA...AND THE FOLLOWING RIVERS FLOWING OFF THE CASCADES...THE SNOHOMISH AT CARNATION...THE PUYALLUP RIVER NEAR ORTING AND THE LOWER REACHES OF THE CHEHALIS RIVER. IF MORE RAIN FALLS THAN IS CURRENTLY ANTICIPATED THEN A FEW ADDITIONAL RIVERS WOULD BE ADDED TO THIS LIST. THIS PRECIPITATION PATTERN IS NOT GOOD FOR GENERATING SIGNIFICANT RAINS IN THE GREEN RIVER BASIN...SO NO FLOODING IS EXPECTED ON THE GREEN RIVER DURING THE PERIOD. $$ CERNIGLIAIssuing Weather Forecast Office Homepage
