FEBRUARY 2025 BROUGHT COOLER AND WETTER THAN NORMAL CONDITIONS TO
SOUTHEAST WASHINGTON AND THE SOUTH IDAHO PANHANDLE.  BUT IT WAS A
MONTH OF SWINGS FEATURING BOTH THE COLDEST AND WARMEST TEMPERATURES
OF THE WINTER. THE FIRST 3 WEEKS BROUGHT SEVERAL ROUNDS OF LIGHT TO
MODERATE RAIN AND SNOW. THE EXCEPTION IS A STORM ON THE 4TH AND 5TH
THAT BROUGHT HEAVY SNOW TO THE REGION.  SNOW REPORTS INCLUDE 12" IN
REUBENS, 10" ANATONE, AND 6" AT THE LEWISTON AIRPORT. BY THE 17TH
THE SNOW DEPTH INCREASED TO THE HIGHEST LEVEL OF THE SEASON IN
MOSCOW WITH 10". THE COLDEST TEMPERATURES OF THE WINTER ALSO
OCCURRED DURING THIS STRETCH FROM THE 9TH THROUGH THE 13TH. SOME OF
THE COLDEST READINGS INCLUDE -19F IN GARFIELD, -14F IN MOSCOW, AND
-13F IN PULLMAN. THIS COLD SPELL WOULD SOON BE IN THE REAR VIEW
MIRROR AS THE WARMEST TEMPERATURES OF THE WINTER ARRIVED ON THE 27TH
AND 28TH WITH HIGHS IN LEWISTON REACHING THE MID 60S. THE RAPID WARM
THOUGH WAS BAD NEWS AS THE RAPID SNOW MELT COMBINED WITH PERIODS OF
RAIN AND WINDY CONDITIONS RESULTED IN RAPID RISES ON CREEKS AND
STREAMS WITH FLOODING MOST PRONOUNCED FROM THE SPOKANE AREA DOWN
THROUGH THE PALOUSE. SEVERAL TOWNS WERE INUNDATED WITH WATER
INCLUDING GARFIELD, OAKESDALE, THORNTON, ROSALIA, COLFAX, PLAZA,
PALOUSE, PULLMAN, MOSCOW, AND EDWALL. SEVERAL ROADS WERE CLOSED AT
ONE POINT DUE TO WATER OVER ROADS INCLUDING US 2 JUST WEST OF
FAIRCHILD AFB, US 27 FROM OAKESDALE TO EDEN, AND PORTIONS OF STATE
ROUTES 23, 25, 231, AND 272. OAKESDALE WAS ONE OF THE HARDEST HIT
TOWNS WITH WATER FROM A FLOODED CREEK RUNNING INTO SEVERAL HOMES.
THE TOWN OF PALOUSE WAS ALSO HARD HIT WAS WATER IN THE BASEMENT FOR
SEVERAL BUILDINGS ALONG THE PALOUSE RIVER. THE WATER WAS ESTIMATED
TO BE AT LEAST 3 FEET DEEP. THE PALOUSE RIVER AT POTLATCH CRESTED AT
17.2 FEET WHICH WAS THE 11TH HIGHEST ON RECORD. HANGMAN CREEK
CRESTED NEAR THE MODERATE FLOOD STAGE OF 13 FEET. PARADISE CREEK ON
THE PALOUSE CRESTED AT 11.21 FEET WHICH WAS THE 3RD HIGHEST ON
RECORD. 48 HOUR PRECIPITATION TOTALS INCLUDE 1.99" IN SAINT MARIES,
1.41" COLFAX, 1.39" PULLMAN, 1.35" LINDEN, AND 1.31" IN MOSCOW.
WINDY CONDITIONS OCCURRED FROM THE 23RD THROUGH THE 25TH WITH PEAK
GUSTS NEAR 50 MPH EACH DAY AT THE PULLMAN AIRPORT.

SEVERAL RECORDS WERE SET DURING THE MONTH AT THE LEWISTON AIRPORT.
THIS INCLUDES RECORD PRECIPITATION OF 0.39 INCHES AND RECORD
SNOWFALL OF 6.0 INCHES ON THE 4TH.  ON THE 19TH A RECORD DAILY
