IT WAS ANOTHER RELATIVELY COOL AND DRY SUMMER MONTH AT SOUTH BEND.
THE AVERAGE MONTHLY TEMPERATURE WAS MORE THAN 3 DEGREES BELOW NORMAL
AND PRECIPITATION WAS MORE THAN AN INCH BELOW NORMAL. THE
COMBINATION OF DRY AND RELATIVELY COOL WEATHER DID MAKE FOR A
COMFORTABLE MONTH WITH ONLY A FEW WARM AND MUGGY DAYS.

THERE WERE JUST 7 DAYS DURING AUGUST WITH AN AVERAGE TEMPERATURE
ABOVE NORMAL AND THERE WAS ONLY ONE DAY, THE 21ST, WITH AN AVERAGE
TEMPERATURE MORE THAN 5 DEGREES ABOVE NORMAL. THE REMAINING 24 DAYS
OF AUGUST SAW 3 DAYS WITH NORMAL AVERAGE TEMPERATURES AND 21 DAYS
WITH BELOW NORMAL TEMPERATURES. THE LAST 10 DAYS OF THE MONTH WERE
ALL BELOW NORMAL AND THERE WAS A STRETCH OF 11 STRAIGHT DAYS FROM
THE 4TH TO THE 14TH WITH BELOW NORMAL TEMPERATURES.

DESPITE ALL OF THE BELOW NORMAL TEMPERATURES...AUGUST OF 2017 WAS
JUST THE 13TH COOLEST AUGUST ON RECORD AT SOUTH BEND WITH AN AVERAGE
TEMPERATURE OF 68.0. THIS WAS 3.3 DEGREES BELOW NORMAL. THE COOLEST
AUGUST ON RECORD WAS 1915 WITH AN AVERAGE TEMPERATURE OF 65.5. THE
HIGHEST TEMPERATURE THIS AUGUST WAS 88 ON THE 16TH. ONLY 7 OTHER
AUGUST MONTHS HAVE HAD COOLER MONTHLY MAXIMUM TEMPERATURES AND THERE
HAVE BEEN 19 MONTHS OF AUGUST WHERE THE HIGH TEMPERATURE DID NOT
REACH 90 DEGREES. THE COOLEST TEMPERATURE WAS 45 ON THE 25TH. THIS
RANKED AS THE 25TH COOLEST AUGUST TEMPERATURE ON RECORD. THE RECORD
COOLEST AUGUST TEMPERATURE IS 40 SET IN 1911, 1927 AND 1965.

PRECIPITATION FOR THE MONTH WAS JUST 2.19 INCHES, 1.57 INCHES BELOW
NORMAL. THIS RANKED AS THE 30TH DRIEST AUGUST ON RECORD. THE YEAR
1950 HOLDS THE RECORD FOR THE DRIEST AUGUST WITH JUST 0.32 INCHES OF
PRECIPITATION. AUGUST 2017 HAD JUST 7 DAYS WITH MEASURABLE
PRECIPITATION. NEARLY HALF OF THE MONTHLY RAINFALL FELL ON THE 3RD
