JULY 2016 OVERALL WAS AN ACTIVE MONTH ACROSS THE REGION WITH
SEVERAL ROUNDS OF SHOWERS AND THUNDERSTORMS.  HOWEVER THE MAJORITY
OF THESE STORMS TRACKED ACROSS NORTH CENTRAL AND NORTHEAST
WASHINGTON INTO THE NORTH IDAHO PANHANDLE.  FOR SOUTHEAST WASHINGTON
AND THE SOUTH IDAHO PANHANDLE THE MONTH FINISHED WITH TEMPERATURES
NEAR TO SLIGHTLY BELOW NORMAL WITH ABOVE NORMAL RAINFALL.  MOST OF
THIS RAIN FELL ON THE 9TH AND 10TH AS A LOW PRESSURE SYSTEM TRACKED
ACROSS NE OREGON AND CENTRAL IDAHO SENT A BAND OF RAIN SHOWERS AND
ISOLATED THUNDERSTORMS INTO THE AREA. UNSEASONABLY COOL AND WET
WEATHER OCCURRED ON THE 10TH WITH LEWISTON ONLY MAKING IT TO 60
DEGREES FOR A HIGH TEMPERATURE.  THIS WAS THE 3RD COLDEST HIGH
TEMPERATURE EVER RECORDED IN LEWISTON FOR THE MONTH OF JULY DATING
BACK TO 1881.  OVER THE TWO DAY PERIOD THE LEWISTON AIRPORT PICKED
UP 1.26 INCHES OF RAIN. ON THE 19TH A THUNDERSTORM CLIPPED THE
NORTHWEST EDGE OF LEWISTON PRODUCING HEAVY RAIN AND A WIND GUST TO
43 MPH.

ONE RECORD WAS SET DURING THE MONTH AT THE LEWISTON AIRPORT.  ON THE
9TH 0.97 INCHES OF RAIN WAS RECORDED SETTING A RECORD FOR THE DATE.
