WETTEST SEPTEMBER SINCE 2016.
THE MONTH BEGAN WITH A TRIO OF 90S AND A HANDFUL OF SEVERE
THUNDERSTORM DAYS, WITH WARNINGS ISSUED ON THE 3RD, 4TH, AND 5TH. WE
NOTCHED ONE ADDITIONAL 90-DEGREE DAY ON THE 15TH, BRINGING THE
MONTH`S TOTAL TO 4, WHICH IS THE MOST SINCE 2018 (5). THE DAILY
AVERAGE TEMPERATURE FINALLY DIPPED BELOW NORMAL ON THE 14TH, BUT
ONLY FOR ONE DAY. THE RENEWED HEAT OCCURRED AS A LARGE UPPER-LEVEL
RIDGE MOVED IN ONCE MORE. A TASTE OF FALL ARRIVED IN THE LATTER
THIRD OF THE MONTH WHEN HIGHS IN THE 60S AND EVEN SOME LOWS IN THE
40S WERE COMMON. THE AVERAGE TEMPERATURE FOR THE MONTH WAS 67.9
WHICH IS 3.1 DEGREES ABOVE NORMAL AND RANKS AS THE 18TH WARMEST ON
RECORD. NO TEMPERATURE RECORDS WERE SET THIS MONTH.
DUE TO THE AFORMENTIONED UPPER-LEVEL RIDGE, WE FOUND OURSELVES
WITHIN THE "RING OF FIRE" PATTERN AT TIMES. IN THIS PATTERN,
COMPLEXES OF THUNDERSTORMS RIDE ATOP A RIDGE IN PLACE. RAINFALL FOR
THE MONTH TOTALED 4.99 INCHES WHICH IS 1.99" ABOVE NORMAL AND RANKS
AS THE 15TH WETTEST ON RECORD, AND WETTEST SINCE 5.44 INCHES IN
2016. ONE DAILY RAINFALL RECORD WAS SET: SEPTEMBER 17TH RECORDED
2.01 INCHES, BREAKING THE PREVIOUS RECORD OF 0.95 SET IN 1969.
THE STRETCH FROM SEPTEMBER 15TH THROUGH 20TH REPRESENTED 94% OF THE
MONTH`S RAINFALL TOTAL: 4.71 INCHES. DURING THIS STRETCH, RECORD
RIVER FLOODING OCCURRED ALONG THE WABASH RIVER IN ADAMS COUNTY AT
LINN GROVE. AN AUTOMATED GAUGE RECORDED A WATER LEVEL OF 14.86 FEET,
EXCEEDING THE PREVIOUS RECORD OF 14.8 SET IN 2003. ELSEWHERE,
INSTANCES OF URBAN AND LOW-LYING FLOODING WERE NOTED.
