ONSHORE FLOW WILL KEEP TEMPERATURES NEAR SEASONAL
NORMALS, KEEP DAYTIME RH VALUES ABOVE CRITICAL THRESHOLDS AND
MAINTAIN GOOD TO EXCELLENT OVERNIGHT RH RECOVERIES. A WEAK SYSTEM
PASSING JUST TO THE NORTH OF THE AREA WEDNESDAY WILL BRING SLIGHTLY
COOLER TEMPERATURES AND A SLIGHT CHANCE FOR SHOWERS AND THUNDERSTORMS
IN THE NORTH CASCADES. A WARMING TREND AND PERSISTENT DRY CONDITIONS
WILL ELEVATE FIRE WEATHER CONCERNS FOR THE END OF THE WEEK.
