...BELOW NORMAL TEMPERATURES CONTINUE INTO SEPTEMBER...

THE COOL PATTERN CONTINUED THROUGH SEPTEMBER WITH COOLER THAN NORMAL
TEMPERATURES AND BELOW NORMAL PRECIPITATION ACROSS NORTHERN INDIANA
AND SOUTHWEST LOWER MICHIGAN. BELOW NORMAL PRECIPITATION DID NOT
HELP THE ONGOING MODERATE DROUGHT CONDITIONS...ALTHOUGH COOL TEMPS
AND SHORTER DAYS HAVE ALLOWED AREA VEGETATION TO REMAIN GREEN.
HYDROLOGIC CONDITIONS ARE STILL POOR AS LAKE...RIVER...AND STREAM
LEVELS REMAIN WELL BELOW NORMAL. MANY AREAS SAW THEIR FIRST FROST
BETWEEN THE 19TH AND 24TH AS A FEW NIGHTS DROPPED TO NEAR FREEZING
IN OUTLYING AREAS.

THE AVERAGE TEMPERATURE FOR SEPTEMBER AT SOUTH BEND WAS 63.0
DEGREES...0.9 DEGREES BELOW NORMAL. THIS TIES FOR THE 33RD COOLEST
SEPTEMBER ON RECORD AT SOUTH BEND. THE AVERAGE HIGH TEMPERATURE WAS
73.6 AND THE AVERAGE LOW TEMPERATURE WAS 52.4. THE TEMPERATURE
REACHED 90 DEGREES 1 DAY...THE 3RD...AND 80 DEGREES OR HIGHER ON 9
DAYS...THE 1ST THROUGH 4TH...THE 6TH AND 7TH...AND THE 11TH THROUGH
13TH. THE WARMEST TEMPERATURE WAS 90 ON THE 3RD AND THE COOLEST
TEMPERATURE WAS 37 ON THE 24TH.

THE MONTHLY PRECIPITATION TOTAL WAS 2.03 INCHES...1.50 INCHES BELOW
NORMAL. THIS RANKS AS THE 35TH DRIEST SEPTEMBER FOR THE PERIOD 1893
TO 2012. MEASURABLE PRECIPITATION FELL ON 11 DAYS BUT THERE WAS
NEVER A HALF INCH OR MORE ON ANY DAY. THE HIGHEST DAILY RAINFALL
OCCURRED ON THE 5TH...WHEN 0.49 INCHES FELL.
