AUGUST 2017 WAS ONCE AGAIN WARMER AND DRIER THAN NORMAL ACROSS NORTH
CENTRAL WASHINGTON.  THE FIRST 11 DAYS BROUGHT WARM AND SMOKY
CONDITIONS AS AN UPPER RIDGE SET UP OFF THE COAST RESULTING IN
NORTHWEST FLOW WHICH BROUGHT SMOKE FROM BRITISH COLUMBIA INTO THE
REGION.  THE 4TH WAS ESPECIALLY SMOKY WITH VISIBILITY DOWN TO 1 MILE
AT WENATCHEE...EPHRATA...AND MOSES LAKE.  ON THE 7TH AND 8TH A WEAK
SYSTEM BROUGHT ISOLATED MOUNTAIN THUNDERSTORMS.  THE WENATCHEE
AIRPORT WARMED INTO THE 90S EACH DAY FROM THE 1ST THROUGH THE
12TH...WHICH COMBINED WITH THE LATE JULY HEAT MADE FOR 19
CONSECUTIVE DAYS OF 90 OR HIGHER WHICH WAS THE SECOND HIGHEST ON
RECORD.  A SIGNIFICANT COOL DOWN ON THE 13TH AND 14TH BROUGHT LIGHT
SHOWERS...WITH HIGHS ONLY IN THE UPPER 70S ON THE 14TH.  WINDY
CONDITIONS ALSO HELPED CLEAR THE SMOKE OUT OF THE REGION WITH A PEAK
WIND OF 40 MPH AT THE WENATCHEE AIRPORT ON THE 13TH.  THE WEATHER
BECAME SEASONAL FROM THE 15TH THROUGH THE 26TH WITH GENERALLY DRY
CONDITIONS AND NORMAL TEMPERATURES.  ALTHOUGH A PERIOD OF DRY AND
WINDY CONDITIONS FROM A DRY COLD FRONT LATE ON THE 16TH AND EARLY ON
THE 17TH CONTRIBUTED TO RAPID FIRE SPREAD OF THE MONUMENT HILL FIRE
NEAR QUINCY WITH WENATCHEE REPORTING A PEAK WIND GUST OF 40 MPH.  AN
UPPER RIDGE BUILT IN AT THE END OF THE MONTH WITH HOT TEMPERATURES
IN THE 90S RETURNING. THIS ALLOWED REGIONAL FIRES TO BECOME MORE
ACTIVE WITH A RETURN OF HAZY SKIES.

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