AFTER A RECORD BREAKING HOT JUNE...THE FIRST 9 DAYS OF JULY BROUGHT
MORE OF THE SAME WITH HOT TEMPERATURES ACROSS SOUTHEAST WASHINGTON
AND THE SOUTH IDAHO PANHANDLE.  TEMPERATURES FOR THE FIRST 9 DAYS
WERE CONSISTENTLY BETWEEN 10 TO 15 DEGREES ABOVE NORMAL WITH HIGH
TEMPERATURES ON SIX OF THESE DAYS REACHING 100 TO 105.  THE STREAK
OF HEAT FINALLY CAME TO AN END ON THE 10TH AS HIGH PRESSURE BROKE
DOWN.  SHOWERS AND THUNDERSTORMS RESULTED WITH FLASH FLOODING
CLOSING HIGHWAY 195 FOUR MILES NORTH OF CLARKSTON. THE STORMS ALSO
DOWNED A TREE IN OAKESDALE.  ON THE 11TH ANOTHER STORM TRACKED FROM
THE BLUE MOUNTAINS BEFORE CLIPPING THE SOUTHEAST FRINGES OF
LEWISTON.  A SPOTTER IN ASOTIN COUNTY REPORTED A HALF INCH OF RAIN
IN 20 MINUTES.  THE 12TH THROUGH THE 24TH BROUGHT UNEVENTFUL WEATHER
WITH NORMAL TEMPERATURES AND GENERALLY DRY WEATHER. A COOLER AND
SHOWERY WEATHER PATTERN CAME IN FROM THE 25TH THROUGH THE 27TH
BEFORE A RETURN TO TYPICAL LATE JULY CONDITIONS TO FINISH OUT THE
MONTH.

NO RECORDS WERE SET DURING THE MONTH AT THE LEWISTON AIRPORT.
