JULY 2017 WAS VERY DRY ALONG WITH WARMER THAN NORMAL TEMPERATURES
ACROSS NORTHEAST WASHINGTON AND THE NORTH IDAHO PANHANDLE.  WHILE
THERE WERE NO RECORD BREAKING HEAT SPELLS WITH JUST TWO DAYS OF
SPOKANE WARMING INTO THE UPPER 90S TO NEAR 100...SPOKANE REACHED 90
OR HIGHER ON 14 DAYS WITH THE JULY NORMAL ONLY AT 8 DAYS.  REGARDING
PRECIPITATION ONLY A TRACE FELL THE ENTIRE MONTH AT THE SPOKANE
AIRPORT.  A TRACE OR LESS FOR THE MONTH OF JULY HAS OCCURRED 15
TIMES SINCE RECORDS BEGAN IN 1881.  ONLY A COUPLE THUNDERSTORM DAYS
OCCURRED DURING THE MONTH.  THE FIRST WAS ON THE 10TH AS
THUNDERSTORMS TRACKED NEAR THE CANADIAN BORDER FROM LAUIER TO
NORTHPORT.  A LOCALIZED DOWNPOUR HIT BOUNDARY DAM WITH 0.55 INCHES
MAKING IT THE WETTEST STATION IN EASTERN WASHINGTON FOR THE MONTH.
ON THE 15TH AND 20TH SCATTERED DRY THUNDERSTORMS OCCURRED EARLY EACH
DAY RESULTING IN NEW FIRES.  MOST OF THESE WERE FIRES WERE
SMALL...EXCEPT THE NOISE CREEK FIRE NEAR SULLIVAN LAKE AND THE NORTH
HUGHES FIRE 14 MILES ENE OF METALINE FALLS.

SPOKANE AIRPORT TIED ONE RECORD DURING THE MONTH WHEN THE HIGH
TEMPERATURE REACHED 99 DEGREES ON THE 7TH.
