...A SEASONABLE AUGUST WITH SLIGHTLY ABOVE NORMAL PRECIPITATION...
OVERALL, AUGUST WAS A SEASONABLE MONTH WITH A MAJORITY OF DAYS
HAVING NEAR NORMAL TO SLIGHTLY WARMER THAN NORMAL TEMPERATURES AND
LOW (OR AT LEAST TOLERABLE) HUMIDITY IN SOUTH BEND. THE WARMEST
TEMPERATURE THIS MONTH WAS 88 DEGREES ON AUGUST 8TH AND THE COOLEST
WAS A LOW OF 51 DEGREES ON AUGUST 25TH. ALTHOUGH THERE WERE
OCCASIONAL BOUTS OF WARMTH AND HUMIDITY, THERE WERE NO 90 DEGREE
DAYS THIS MONTH! THIS IS THE FIRST TIME THERE HAVE BEEN ZERO 90+
DEGREE DAYS IN AUGUST SINCE 2019; SOUTH BEND TYPICALLY AVERAGES IS 4
DAYS IN THE 90S EACH AUGUST. OVERALL, SOUTH BEND`S AVERAGE
TEMPERATURE THIS AUGUST WAS 71.7 DEGREES, WHICH IS 1.0 DEGREES ABOVE
NORMAL.
PERSISTENT NORTHWEST FLOW AND THE "RING OF FIRE" PATTERN BROUGHT
WELL ABOVE NORMAL RAINFALL TO NORTHERN AND CENTRAL INDIANA DURING
EARLY TO MID AUGUST. HISTORIC RAINFALL AMOUNTS OF 12"+ AND
WIDESPREAD AREAL/RIVER FLOODING WERE OBSERVED SOUTH OF THE US 30
CORRIDOR. UNFORTUNATELY FOR SOUTH BEND, MUCH OF THIS SETUP MISSED
THE AREA COMPLETELY. A MAJORITY OF FAR SOUTHERN LOWER MICHIGAN AND
FAR NORTHERN INDIANA RECIEVED ANYWHERE FROM 50-100% OF THEIR NORMAL
RAINFALL FOR THE MONTH (COMPARED TO 200-300%+ IN CENTRAL INDIANA).
FOR SOUTH BEND, THERE WERE 2 DAYS THIS AUGUST WITH OVER AN INCH OF
RAIN: AUGUST 9TH (1.12") AND AUGUST 11TH (1.10"). OUTSIDE OF THESE 2
DAYS, A MAJORITY OF THE MONTH`S RAINFALL ADDED UP SLOWLY. SOUTH BEND
TOTALED 4.11" OF RAIN FOR THE MONTH, WHICH IS 0.10" ABOVE NORMAL AND
RANKS AS THE 43RD WETTEST AUGUST. NOTABLY, THIS IS ONLY THE THIRD
TIME IN THE PAST DECADE SOUTH BEND HAS HAD ABOVE NORMAL RAINFALL IN
AUGUST AND THE FIRST SINCE 2020.
THERE WERE NO TEMPERATURE OR PRECIPITATION RECORDS SET THIS MONTH.
