CLIMATE REPORT
NATIONAL WEATHER SERVICE BOISE ID
1137 AM MDT THU SEP 1 2016

AUGUST 2016 WAS DRY AND SEASONABLY WARM, WITH THE AVERAGE
TEMPERATURE WITHIN ONE DEGREE OF NORMAL. THERE WERE NO RECORD HIGHS
OR LOWS.

ONLY TRACES OF RAIN FELL AT THE AIRPORT. THAT`S NOT UNUSUAL, BECAUSE
AUGUST IS THE DRIEST MONTH OF AN AVERAGE YEAR. HISTORICALLY, 25% OF
BOISE AUGUSTS HAD NO MEASURABLE RAINFALL, AND 50% HAD NO MORE THAN A
TENTH OF AN INCH.

WEATHER PATTERNS WERE TYPICAL OF THIS TIME OF YEAR. PACIFIC SYSTEMS
WERE RELATIVELY WEAK, MAINLY MOVING INLAND NORTH OF OUR AREA. MOST
OF THEIR PRECIPITATION WAS CONFINED TO NORTHERN AND CENTRAL IDAHO
AND ADJACENT SECTIONS OF EASTERN WASHINGTON, NORTHERN OREGON, AND
WESTERN MONTANA. BUT EVEN THOSE AREAS WERE DRIER THAN NORMAL, AND
LITTLE IF ANY RAIN FELL ON SOUTHWEST IDAHO.

INCURSIONS OF MONSOON MOISTURE WERE USUALLY DEFLECTED TO THE EAST
AHEAD OF TRAILING PACIFIC COLD FRONTS, SO MEASURABLE RAIN FROM THAT
SOURCE CAME NO CLOSER THAN THE NEVADA BORDER AND EASTERN IDAHO.

AT THE BOISE AIRPORT, WHERE RECORDS GO BACK TO 1940, JUNE THROUGH
AUGUST 2016 RANKED AMONG THE WARMEST AND DRIEST 15 PERCENT OF
SUMMERS.
