APRIL 2025 BROUGHT WARMER AND DRIER THAN NORMAL CONDITIONS TO
NORTHEAST WASHINGTON AND THE NORTH IDAHO PANHANDLE. ISOLATED
THUNDERSTORMS IMPACTED THE REGION ON THE 7TH, 8TH, 19TH, AND 27TH.
MOST OF THIS ACTIVITY WAS FOCUSED NORTH AND EAST OF SPOKANE AROUND
DEER PARK, NEWPORT, RATHDRUM, AND SANDPOINT. MOST OF THESE STORMS
DID NOT PRODUCE SIGNIFICANT IMPACTS WITH BRIEF DOWNPOURS, GUSTY
WINDS, SMALL HAIL, AND OCCASIONAL LIGHTNING. ON THE 19TH, A
STRONGER STORM TRACKED THROUGH CUSICK PRODUCING HEAVY RAIN AND
HAIL. BESIDES THE THUNDERSTORMS, THE OTHER NOTEWORTHY EVENT DURING
THE MONTH WAS WINDY CONDITIONS ON THE 7TH AND 16TH. ON THE 7TH
THE PEAK WIND GUST AT THE SPOKANE AIRPORT REACHED 48 MPH. ON THE
16TH A DRY COLD FRONT DELIVERED GUSTY WINDS WHICH CONTRIBUTED TO
SOME TREE DAMAGE AND POWER OUTAGES IN STEVENS AND PEND OREILLE
COUNTIES WITH 40 MPH GUSTS. A LOCALIZED DUST STORM ALSO
MATERIALIZED AROUND 15 MILES WEST OF RITZVILLE ON INTERSTATE 90
WITH NEAR 0 VISIBILITY LEADING TO A COLLISION AND A 1.5 MILE
BACKUP OF WESTBOUND LANES.
NO RECORDS WERE SET DURING THE MONTH AT THE SPOKANE AIRPORT.
