SEPTEMBER 2017 SURE BROUGHT SOME SIGNIFICANT WEATHER CHANGES TO
NORTH CENTRAL WASHINGTON.  THE MONTH STARTED WHERE AUGUST LEFT OFF
WITH CONTINUED VERY DRY AND WARM CONDITIONS WHICH RESULTED IN A
CONTINUATION OF NUMEROUS ACTIVE WILDFIRES ACROSS
WASHINGTON...OREGON...MONTANA...AND SOUTHERN BRITISH COLUMBIA.  THE
MONTANA FIRES WERE ESPECIALLY ACTIVE...AND THUS WHEN THE WINDS
SHIFTED OUT OF THE NORTHEAST ON THE 4TH...EXTENSIVE SMOKE WAS
BROUGHT INTO THE REGION.  WIDESPREAD VISIBILITY OF ONE TO THREE
MILES WAS OBSERVED FROM THE 4TH THROUGH THE 7TH.  WINDS SHIFTED ON
THE 8TH AND 9TH WITH SMOKE CLEARING THE REGION...BEFORE RETURNING ON
THE 14TH AND 15TH WITH ANOTHER NORTHEAST WIND SHIFT.  THE PATTERN
CHANGED ON THE 17TH...FINALLY BRINGING AN END TO THE SMOKE.  THE
18TH THROUGH THE 21ST WAS MUCH COOLER AND WET. ALTHOUGH MOST OF THE
RAIN SHOWERS MISSED THE WENATCHEE AREA AND THE METHOW VALLEY WITH
LESS THAN .02 INCHES REPORTED. THE HIGH TEMPERATURE IN WENATCHEE
ONLY REACHED 59F ON THE 20TH AFTER REACHING 91F ON THE 12TH. AFTER
THE MID-MONTH COOL DOWN...TEMPERATURES GRADUALLY WARMED ONCE AGAIN
AFTER THAT...REACHING THE MID 70S TO LOWER 80S FROM THE 26TH THROUGH
THE 29TH.

NO RECORDS WERE SET DURING THE MONTH AT THE WENATCHEE AIRPORT.
