SEPTEMBER 2025 FINISHED WITH MUCH ABOVE NORMAL TEMPERATURES FOR
NORTH CENTRAL WASHINGTON. PRECIPITATION AMOUNTS VARIED ACROSS THE
REGION. THE FIRST FIVE DAYS REACHED THE 90S IN WENATCHEE. LIGHTNING
ALSO STARTED FIRES IN THE CASCADES ON THE 1ST INCLUDING THE LOWER
SUGARLOAF FIRE WHICH BY MONTHS END WAS OVER 30,000 ACRES. FROM THE
7TH THROUGH THE 10TH THUNDERSTORMS OCCURRED EACH DAY ALONG THE EAST
SLOPES OF THE CASCADES INTO OKANOGAN VALLEY AND HIGHLANDS. ON THE
14TH COOL AND SHOWERY WEATHER ARRIVED, WITH A FUNNEL CLOUD SPOTTED
WEST OF COULEE CITY, APPROXIMATELY 10 MILES NORTHWEST OF SOAP LAKE.
THE COOLER WEATHER WAS SHORT LIVED AS HIGH TEMPERATURES RETURNED
INTO THE 80S FROM THE 16TH THROUGH THE 20TH. HIGH PRESSURE ON THE
23RD AND 24TH ALLOWED AN INCREASE IN VALLEY SMOKE FOR LAKE
WENATCHEE, CHELAN, ENTIAT, AND WENATCHEE. ON THE 24TH AIR QUALITY
REACHED HAZARDOUS LEVELS IN WENATCHEE. ON THE 25TH A STRONG DRY COLD
FRONT PASSED THROUGH THE REGION BRINGING WINDY CONDITIONS AND VERY
LOW RELATIVE HUMIDITY. VALUES WERE NOTEWORTHY FOR ANY TIME OF THE
YEAR, WITH OMAK DROPPING TO 6 PERCENT. THE WINDS PUSHED SMOKE FROM
FIRES IN THE CASCADES INTO THE COLUMBIA BASIN WITH UNHEALTHY AIR
QUALITY IN MOSES LAKE. PEAK WIND GUSTS INCLUDE 50 MPH IN MATTAWA,
45 MPH OROVILLE, AND 40 MPH AT THE WENATCHEE AIRPORT.
A COUPLE RECORDS WERE BROKEN DURING THE MONTH AT THE WENATCHEE
AIRPORT. ON THE 3RD A RECORD HIGH TEMPERATURE OF 99F WAS SET. ON
THE 21ST JUST .03 INCHES OF RAIN WAS ENOUGH TO SET A DAILY RECORD AS
WELL.
