CLIMATE REPORT...CORRECTED
NATIONAL WEATHER SERVICE BOISE ID
950 AM MDT MON AUG 9 2016

ALTHOUGH JULY`S AVERAGE TEMPERATURE AND TOTAL PRECIPITATION WERE
CLOSE TO NORMAL AT THE AIRPORT, IT WAS AN UNUSUAL MONTH.

THE AVERAGE TEMPERATURE OF 75.4 WAS THE LOWEST JULY AVERAGE SINCE
2001. THE LOW OF 47 ON THE 11TH WAS THE COOLEST JULY TEMPERATURE
SINCE 2000, AND THE HIGH OF 69 ON THE 10TH WAS THE COOLEST JULY
DAILY HIGH SINCE 2001. THE 101 ON THE 27TH, THE HOTTEST DAY OF THE
MONTH, WAS THE LOWEST JULY MONTHLY MAXIMUM SINCE 1997.

BUT THERE WERE NO RECORD DAILY HIGHS OR LOWS.

A NEW DAILY PRECIPITATION RECORD WAS SET ON JULY 10TH, WHEN .27 INCH
OF RAIN WAS RECORDED AT THE AIRPORT. EVEN HEAVIER AMOUNTS WERE
MEASURED ELSWHERE IN THE BOISE AREA, INCLUDING .76 INCH IN EAGLE AND
.61 INCH IN MERIDIAN.

THE WEATHER SYSTEM RESPONSIBLE FOR JULY`S ONLY RAINY DAY WAS A COLD
UPPER LEVEL LOW PRESSURE SYSTEM WHICH FORMED OVER THE BERING SEA ON
THE 5TH AND REACHED THE NORTHWEST COAST ON THE 8TH, STEERED BY THE
FLOW AROUND AN UPPER LEVEL HIGH PRESSURE AREA BETWEEN ALASKA AND
HAWAII.

BOISE WAS JUST FAR ENOUGH NORTH TO BENEFIT FROM THE STORM, WHICH
EXTENDED UNUSUALLY FAR SOUTH FOR THIS TIME OF YEAR. RAINFALL AMOUNTS
DIMINISHED RAPIDLY SOUTH OF BOISE, AND NO RAIN AT ALL WAS MEASURED
SOUTH OF THE NEVADA BORDER.

FROM THE 21ST THROUGH THE END OF THE MONTH A VERY WARM UPPER LEVEL
HIGH PRESSURE RIDGE WAS THE DOMINANT FEATURE OVER THE INTERMOUNTAIN
WEST. TEMPERATURES AT BOISE REACHED TRIPLE DIGITS ON THE 21ST, 25TH,
27TH, 29TH AND 30TH
