FIRE WEATHER PLANNING FORECAST FOR WESTERN WASHINGTON

203 PM PDT SUN SEP 6 2026
DISCUSSION
RAIN SHOWERS LINGER TONIGHT OVER THE MOUNTAINS,
ESPECIALLY IN THE CASCADES AROUND MOUNT RAINIER, BUT THE THREAT OF
LIGHTNING REMAINS LOW. THE LOW PRESSURE SYSTEM MOVES AWAY, WITH DRIER
AND WARMER CONDITIONS DEVELOPING THROUGH THE FIRST HALF OF THE WEEK.
ONSHORE FLOW WILL MAINTAIN EXCELLENT RH RECOVERIES TONIGHT INTO
MONDAY, BUT LIGHT OFFSHORE FLOW MAY BRIEFLY DEVELOP TOWARD MIDWEEK.
THIS COULD BRING DAYTIME HUMIDITIES APPROACHING CRITICAL THRESHOLDS.
ANOTHER DISTURBANCE BRINGS COOLER TEMPERATURES, HIGHER HUMIDITIES,
AND RAIN CHANCES LATE IN THE WEEK.
FORECAST FOR 20 FOOT WIND SPEED (VALLEYS AND RIDGE TOPS) ARE 10
MINUTE AVERAGES REFLECTING RAWS WINDS.
