WASHINGTON INTO THE SOUTH IDAHO PANHANDLE. FOR LEWISTON IT WAS THE
3RD WARMEST JULY ON RECORD. FROM THE 7TH THROUGH THE 22ND, LEWISTON
REACHED 100 OR WARMER EVERY DAY EXCEPT THE 15TH. THE HOTTEST DAY
WAS THE 21ST WHEN THE HIGH TEMPERATURE REACHED 111F. BESIDES THE

PULLMAN/MOSCOW AREAS, AND INTO THE CENTRAL PANHANDLE MOUNTAINS. THE

KNOCKED OUT POWER TO APPROXIMATELY 600 RESIDENTS IN KAMIAH WITH
NEARBY STATIONS REPORTING WIND GUSTS OF 45 TO 55 MPH.
