JANUARY 2026 BROUGHT WARMER AND DRIER THAN NORMAL CONDITIONS TO
SOUTHEAST WASHINGTON AND THE SOUTH IDAHO PANHANDLE. THE FIRST SEVEN
DAYS BROUGHT SEVERAL ROUNDS OF PRECIPITATION, FALLING MOSTLY AS
RAIN, BEFORE CHANGING TO SNOW ON THE 7TH WITH AROUND 2-3 INCHES OF
ACCUMULATION ON THE PALOUSE.  THEN A PROLONGED DRY SPELL ARRIVED
FROM THE 9TH THROUGH THE 27TH.  THE MONTH FINISHED OFF WITH JUST A
FEW BRIEF PERIODS OF LIGHT RAIN.

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