SEPTEMBER 2022 FINISHED WARMER THAN NORMAL ACROSS THE REGION.
SPOKANE AND COEUR D`ALENE AREAS FINISHED WITH NEAR NORMAL
PRECIPITATION FOR THE MONTH THANKS TO ONE WET DAY ON THE 29TH.
MEANWHILE THE NE WA MOUNTAINS AND N IDAHO PANHANDLE WERE DRIER THAN
NORMAL. THE MONTH STARTED OFF HOT WITH HIGH TEMPERATURES ON THE 1ST
AND 2ND REACHING THE MID 90S. THE HEAT CAME TO AN END ON THE 3RD
WITH ISOLATED THUNDERSTORMS OVER THE REGION. MEANWHILE FIRES IN NE
WASHINGTON AND MUCH OF IDAHO CONTINUED TO BURN ACTIVE DURING THE
FIRST HALF OF SEPTEMBER.  FROM THE 9TH THROUGH THE 14TH SMOKE
INCREASED OVER THE REGION AS EAST WINDS BROUGHT IN SMOKE FROM
SEVERAL WILDFIRES INTO EASTERN WASHINGTON. FOR SPOKANE THE WORST OF

REACHED UNHEALTHY LEVELS. THUNDERSTORMS ON THE 14TH BROUGHT SOME
RELIEF FROM THE SMOKE.  FOR THE REMAINDER OF THE MONTH HIGHS WERE
MAINLY IN THE UPPER 60S AND 70S, EXCEPT FOR A BRIEF AND RAPID WARMUP
ON THE 26TH AND 27TH WHERE SPOKANE REACHED 90F. THIS WARMTH CAME TO
A QUICK END ON THE 29TH WITH RAIN OVER THE REGION. COEUR D`ALENE AND
BAYVIEW ONLY MANAGED TO REACH 55F.  SOME OF THE HIGHER RAIN AMOUNTS
INCLUDE 1.04" IN COEUR D`ALENE AND 0.80" NEAR MOYIE SPRINGS.

A COUPLE RECORDS WERE SET DURING THE MONTH AT THE SPOKANE AIRPORT.
ON THE 27TH A RECORD HIGH TEMPERATURE OF 90F WAS SET.  THIS ALSO
BROKE A RECORD FOR THE LATEST DATE 90F OR WARMER. ON THE 29TH A
DAILY RECORD RAIN OF 0.46 INCHES WAS SET.
