...29TH DRIEST SEPTEMBER ON RECORD RESULTS IN WORSENING DROUGHT...

RECALL THAT ONLY A TRACE OF RAIN HAD FALLEN AT SOUTH BEND FROM
AUGUST 18TH TO 31ST. THIS DRYNESS CONTINUED INTO SEPTEMBER AS
MEASURABLE PRECIPITATION WAS NOT RECORDED UNTIL THE 6TH (0.60
INCHES). AS A RESULT, DROUGHT CONDITIONS CAME BLAZING BACK TO THE
REGION ACCORDING TO THE US DROUGHT MONITOR. ON SEPTEMBER 5TH, JUST
OVER 65% OF THE FORECAST AREA WAS EXPERIENCING "ABNORMALLY DRY"
CONDITIONS, WHILE ABOUT 3% WAS DEEMED TO BE IN A "MODERATE DROUGHT".
BY SEPTEMBER 26TH, 80% OF THE FORECAST AREA WAS EXPERIENCING
"MODERATE DROUGHT". LAWNS BECAME DORMANT. SOIL WAS VERY DRY AND
CRACKED, AND VERY LOW WATER LEVELS WERE NOTED ACROSS PONDS, CREEKS,
STREAMS AND RIVERS. PASTURE CONDITIONS DETERIORATED AND SOYBEAN PODS
WERE SHATTERING IN CENTRAL INDIANA. PRECIPITATION FOR THE MONTH
TOTALED 1.71 INCHES WHICH IS THE 29TH DRIEST ON RECORD. THIS IS THE
DRIEST SINCE 2020 WHEN 1.68 INCHES WAS OBSERVED.

PAIRED WITH THE DRY CONDITIONS WERE ABOVE NORMAL TEMPERATURES. A
BLOCKING RIDGE WAS A FACTOR ONCE AGAIN. THERE WERE THREE 90-DEGREE
DAYS EARLY IN THE MONTH WHICH IS ABOVE THE NORMAL VALUE OF 1.5 DAYS
IN SEPTEMBER. (THE ANNUAL TOTAL IS NOW 15, WHICH IS ABOVE THE NORMAL
VALUE OF 13.5 DAYS PER YEAR.) THE MIDDLE OF THE MONTH WAS COOLER,
WITH A NINE-DAY STRETCH OF BELOW-NORMAL TEMPERATURES. THIS WAS
QUICKLY OFFSET BY UNSEASONABLY MILD CONDITIONS ON THE 21ST AND 22ND
WHICH SAW A DAILY AVERAGE TEMPERATURE 10 AND 11 DEGREES ABOVE
NORMAL, RESPECTIVELY. THE AVERAGE TEMPERATURE FOR THE MONTH WAS 66.6
DEGREES WHICH IS 2.9 DEGREES ABOVE NORMAL. THIS RANKS AS THE
33RD WARMEST ON RECORD, TIED WITH 1930 AND 1915.

NO RECORDS WERE SET THIS MONTH.
