JANUARY 2024 BROUGHT BELOW NORMAL TEMPERATURES TO SOUTHEAST
WASHINGTON AND THE SOUTH IDAHO PANHANDLE. PRECIPITATION WAS ABOVE
NORMAL IN THE LEWISTON AREA WHILE BELOW NROMAL IN THE CENTRAL
PANHANDLE MOUNTAINS. THE MONTH WAS ACTIVE WITH SEVERAL SIGNIFICANT
WEATHER EVENTS. ON THE 9TH A DEEP LOW PRESSURE TRACKED ACROSS
SOUTHERN BRITISH COLUMBIA PRODUCING STRONG WINDS OVER THE REGION.
PEAK WIND GUSTS INCLUDE 64 MPH AT ALDER RIDGE IN THE BLUE MOUNTAINS,
62 MPH NEAR POMEROY, AND 56 MPH AT THE PULLMAN AIRPORT. THEN ON THE
11TH A STRONG ARCTIC FRONT DELIVERED SNOW SQUALLS FOLLOWED BY BITTER
COLD. A QUICK 7 INCHES OF SNOW FELL IN LEWISTON, WHILE A CLARKSTON
RESIDENT REPORTED 5 INCHES IN 2.5 HOURS. MEANWHILE THUNDERSNOW WAS
REPORTED NEAR ALPOWA SUMMIT. THEN THE INLAND NORTHWEST WENT IN THE
DEEP FREEZE. ON THE 13TH THE HIGH TEMPERATURE AT THE LEWISTON
AIRPORT ONLY REACHED 2F, MAKING IT THE COLDEST READING SINCE 1983!
BUT THE WIND CHILLS THAT MORNING MADE IT FEEL EVEN COLDER. WIND
CHILL READINGS BOTTOMED OUT AT -40F UNIONTOWN, -35F ANATONE, -32F
PULLMAN AIRPORT, -31F REUBENS, -30F RITZVILLE, -29F LAPWAI, -25F
CRAIGMONT, AND -21F AT THE LEWISTON AIRPORT.  AS ABRUPT AS THE MAJOR
COLD SPELL OCCURRED, THE MONTH WOULD CONCLUDE WITH RECORD WARMTH.
DURING THE TRANSITION TO WARMER TEMPERATURES OCCASIONAL ROUNDS OF
SNOW AND A WINTRY MIX WERE OBSERVED FROM THE 17TH THROUGH THE 21ST.
BUT THEN THE 26TH THROUGH THE 31ST WERE EXCEPTIONALLY MILD WITH HIGH
TEMPERATURES WARMING INTO THE 50S, WITH LEWISTON REACHING A BALMY 63
DEGREES ON THE 29TH.

SEVERAL RECORDS WERE BROKEN DURING THE MONTH AT THE LEWISTON
AIRPORT.  ON THE 13TH A RECORD LOW TEMPERATURE OF -10F WAS RECORDED
ALONG WITH A RECORD COLD HIGH TEMPERATURE OF 2F. RECORD HIGH
TEMPERATURES OF 59F AND 63F WERE SET ON THE 28TH AND 29TH
RESPECTIVELY.  RECORD WARM LOW TEMPERATURES OF 44F AND 46F WERE SET
