JUNE 2025 FINISHED WITH ABOVE NORMAL TEMPERATURES AND BELOW NORMAL
PRECIPITATION FOR SOUTHEAST WASHINGTON INTO THE SOUTH IDAHO
PANHANDLE. FOR THE LEWISTON AND PULLMAN AIRPORTS THE THIRD DRIEST
JUNE ON RECORD WAS RECORDED WITH 0.08 AND 0.10 INCHES OF PRECIPITATION
RESPECTIVELY.
THE FIRST FEW DAYS OF JUNE STARTED WITH NEAR NORMAL TEMPERATURES
WITH HIGH TEMPERATURES IN THE MID TO UPPER 70S IN LEWISTON BEFORE
TEMPERATURES SURGED INTO THE 90S TO NEAR THE CENTURY MARK FROM THE
7TH THROUGH THE 10TH. TEMPERATURES THEN DROPPED BACK DOWN TO
SLIGHTLY ABOVE SEASONAL NORMALS FOR A WEEK BEFORE A LARGE LOW
PRESSURE SYSTEM TRACKING THROUGH THE REGION BROUGHT A BRIEF DOSE
OF COOLER WEATHER WITH HIGHS ONLY IN THE UPPER 60S TO LOW 70S ON THE
20TH THROUGH THE 22ND. WETTING RAINS FELL ACROSS THE CENTRAL
PANHANDLE MOUNTAINS DURING THE EVENING OF THE 22ND WITH A QUARTER TO
HALF INCH OF RAIN. BUT THE THREE DAY EVENT SPARED MUCH OF SOUTHEAST
WASHINGTON AND THE LEWISTON AREA FROM SIGNIFICANT RAIN, WITH LESS
THAN A TENTH OF AN INCH.
ONE DAILY RECORD WAS TIED DURING THE MONTH AT THE LEWISTON AIRPORT,
WITH A HIGH TEMPERATURE OF 101F ON THE 9TH.
