...SEPTEMBER WAS RELATIVELY MILD WITH BELOW NORMAL PRECIPITATION...

THE MONTH OF SEPTEMBER COULD BE BROKEN DOWN INTO THIRDS...WITH THE
BEGINNING AND ENDING THIRDS WARM AND THE MIDDLE THIRD QUITE COOL.
THE RESULT WAS A NEAR NORMAL MONTH IN TERMS OF TEMPERATURES WITH
MONTHLY PRECIPITATION SLIGHTLY BELOW NORMAL.

THE MONTH BEGAN QUITE WARM WITH HIGH TEMPERATURES IN THE 80S ON THE
FIRST FOUR DAYS AND A HIGH OF 91 ON THE 5TH BEFORE A STRONG COLD
FRONT SWEPT THROUGH THE AREA. THIS FRONT BROUGHT SEVERAL INCHES OF
BENEFICIAL RAINFALL TO THE REGION WITH OVER AN INCH FALLING AT SOUTH
BEND. SEVERE WEATHER ALSO OCCURRED WITH THUNDERSTORMS PRODUCING
LARGE HAIL AND DAMAGING WINDS IN A FEW LOCATIONS.

THIS FIRST COLD FRONT DROPPED TEMPERATURES BACK INTO THE 70S AND
NEAR NORMAL FOR EARLY SEPTEMBER BUT A SECOND COLD FRONT ALONG WITH
REMNANT MOISTURE FROM PACIFIC HURRICANE NORBERT BROUGHT MORE HEAVY
RAINFALL TO THE AREA ON SEPTEMBER 10TH. TEMPERATURES BEHIND THIS
FRONT DROPPED WELL BELOW NORMAL FOR THE MIDDLE PORTION OF THE MONTH.
AVERAGE DAILY TEMPERATURES BETWEEN THE 11TH AND 23RD OF SEPTEMBER
WERE BELOW NORMAL EACH DAY EXCEPT FOR THE 20TH. TEMPERATURES WERE AS
MUCH AS 13 DEGREES BELOW NORMAL ON THE 13TH. LOW TEMPERATURES WERE
IN THE 40S EACH MORNING DURING THIS STRETCH.

TEMPERATURES MODERATED BRIEFLY ON THE 20TH WITH HIGHS BACK AROUND 80
AHEAD OF ANOTHER STRONG COLD FRONT. THIS FRONT BROUGHT RAIN AND
SEVERE WEATHER BACK TO THE REGION DURING THE LATE AFTERNOON HOURS ON
THE 20TH. MANY AREAS EXPERIENCED WIND DAMAGE AND HEAVY RAINFALL FROM
A LINE OF THUNDERSTORMS THAT MOVED THROUGH AHEAD OF THE MAIN COLD
FRONT. THE COOLER WEATHER BEHIND THIS FRONT WAS BRIEF AS MILD AND
DRY WEATHER RETURNED TO END THE MONTH. HIGH TEMPERATURES CLIMBED
BACK INTO THE 80S ON FOUR OF THE LAST 5 DAYS TO END SEPTEMBER.

THE AVERAGE MONTHLY TEMPERATURE WAS 63.2 DEGREES...0.7 DEGREES BELOW
NORMAL. THIS RANKED AS THE T-39TH COOLEST SEPTEMBER ON RECORD. THE
HIGHEST TEMPERATURE WAS 91 ON THE 5TH AND THE COOLEST WAS 40 ON THE
22ND. TOTAL PRECIPITATION WAS 2.71 INCHES...0.82 INCHES BELOW
NORMAL. THIS RANKED AS THE T-47TH DRIEST SEPTEMBER ON RECORD. THE
GREATEST 24 HOUR RAINFALL WAS 1.14 INCHES ON THE 5TH AND 6TH. A
TOTAL OF 11 DAYS IN SEPTEMBER HAD MEASURABLE PRECIPITATION AND TWO
OF THESE DAYS HAD GREATER THAN ONE HALF INCH OF RAINFALL.
