UNCOMFORTABLY HOT AND HUMID FOR A FEW DAYS THIS MONTH, OTHERWISE
COOL THANKS TO RATHER PERSISTENT NORTHWEST FLOW ALOFT. THIS PATTERN
IS GENERALLY NOT CONDUCIVE FOR RAINFALL, WHICH IS REFLECTED BY BELOW-
NORMAL PRECIPITATION.
FOLLOWING THE SECOND-WETTEST JULY ON RECORD, THE SO-CALLED FAUCET
TURNED OFF AND THE MONTH ENDED WITH ONLY 2.11 INCHES OF
PRECIPITATION; 1.90 INCHES BELOW NORMAL. THIS RANKS AS THE 31ST
DRIEST ON RECORD. THIS WAS ONLY SLIGHTLY MORE THAN AUGUST 2022, WHEN
2.03 INCHES WAS RECORDED. THE STATE OF INDIANA HAS GENERALLY BEEN
WORKING ITS WAY OUT OF ABNORMALLY DRY OR DROUGHT CONDITIONS THIS
SUMMER. HOWEVER, ABNORMALLY DRY CONDITIONS LOOM AGAIN AS SOUTH BEND
HAS ONLY RECORDED A TRACE OF RAIN SINCE AUGUST 18.
AN UPPER-LEVEL RIDGE THAT HAS DOMINATED THE SOUTHERN PLAINS THIS
SUMMER WAS NUDGED EASTWARD INTO THE GREAT LAKES FOR A FEW DAYS LATE
THIS MONTH. THIS RESULTED IN WELL-ABOVE NORMAL DAILY TEMPERATURES
FROM THE 20TH THROUGH 26TH. THE PEAK OF THE HEAT OCCURRED ON THE
23RD AND 24TH WHEN SOUTH BEND RECORDED A HEAT INDEX OF 114 AND 115,
RESPECTIVELY. ACCORDING TO THE MIDWESTERN REGIONAL CLIMATE CENTER,
FROM 1973 TO 2018, SOUTH BEND SEES WELL LESS THAN 1 HOUR ON AVERAGE
ANNUALLY WITH A HEAT INDEX OF 110 IN AUGUST.
ONE RECORD WAS SET THIS MONTH. THE LOW TEMPERATURE OF 77 ON THE 24TH
WAS THE WARMEST LOW TEMPERATURE RECORDED. IT BREAKS THE PREVIOUS
RECORD OF 75 SET IN 1975.
THE AVERAGE TEMPERATURE FOR THE MONTH WAS 71.5 DEGREES WHICH IS NEAR
THE NORMAL OF 70.7 DEGREES.
