=====================================================================
...A SHIFT IN THE PATTERN BRINGS CHANGE TO BEGIN FALL 2012...

FOR THE FIRST TIME IN QUITE A LONG TIME, NEARLY AN ENTIRE MONTH HAS
BEEN CHARACTERIZED BY FREQUENT TROUGHING OVER THE GREAT LAKES. THE
RESULT FOR THE FLINT AND SAGINAW AREAS HAS BEEN A NOTABLE SHIFT FROM
WARMER THAN NORMAL TEMPERATURES, A TREND WHICH STILL CONTINUED
THROUGH THE FIRST WEEK OF THE MONTH, TO COOLER THAN NORMAL WEATHER.
AFTER SEEING HIGH TEMPERATURES TOP 80 DEGREES ON THE FIRST SIX DAYS
OF THE MONTH IN FLINT (FIVE OUT OF THE FIRST 6 DAYS IN SAGINAW),
INCLUDING A HIGH OF 90 DEGREES ON SEPTEMBER 3RD, TEMPERATURES HAD
FALLEN INTO THE LOW 70S BY SEPTEMBER 8TH. THE 3 WEEKS WHICH FOLLOWED
WERE MOSTLY CHARACTERIZED BY BELOW NORMAL TEMPERATURES, INCLUDING A
HIGH OF 57 AND 58 AND DEGREES IN FLINT AND SAGINAW RESPECTIVELY ON
SEPTEMBER 23RD. BY THIS TIME, MORNING LOWS WELL INTO THE 30S WERE
BEING OBSERVED. THIS SHIFT TO PERSISTENT TROUGHING AND AND BELOW
NORMAL TEMPERATURES RESULTED IN SEPTEMBER 2012 ENDING WITH AN
AVERAGE TEMPERATURE THAT WAS JUST SLIGHTLY ABOVE THE 30-YEAR
CLIMATOLOGICAL NORMAL IN FLINT (+0.3 DEGREES) AND SLIGHTLY BELOW IN
SAGINAW (-0.1 DEGREES). THUS, DESPITE THE NOTEWORTHY PATTERN CHANGE,
FLINT STILL MANAGED TO SQUEAK OUT ITS 17TH STRAIGHT MONTH WITH AN
AVERAGE TEMPERATURE ABOVE NORMAL.

SEVERE WEATHER REMAINED ON THE QUIET SIDE WITH ONLY 3 SEVERE WEATHER
REPORTS ON SEPTEMBER 5TH FOR WIND AND HAIL IN HURON COUNTY AND ONLY
2 DAYS DURING WHICH THUNDER WAS OBSERVED AT FLINT-BISHOP AIRPORT. NO
THUNDER WAS OBSERVED AT SAGINAW (MBS). FLINT MEASURED 2.58" OF RAIN
FOR THE MONTH, WHICH IS 69% OF ITS 3.75" MONTHLY NORMAL. IN SAGINAW,
2.08" WAS MEASURED, OR 54% OF THE 3.83" SEPTEMBER NORMAL. DESPITE
THE BELOW NORMAL RAINFALL AMOUNTS, THE COMBINATION OF MORE TYPICAL
RAINFALL PATTERNS AND MUCH COOLER TEMPERATURES HAVE ELIMINATED
DROUGHT CONDITIONS OVER ALL OF SOUTHEAST MICHIGAN.

THE AVERAGE HIGH TEMPERATURE FOR THE FLINT AREA WAS 73.7 (38TH
WARMEST ON RECORD), AND +1.4 DEGREES ABOVE THE NORMAL VALUE OF 72.3.
THE AVERAGE HIGH IN SAGINAW WAS 72.5 (49TH WARMEST ON RECORD), +0.4
DEGREES ABOVE THE 72.1 DEGREE NORMAL. FLINT`S AVERAGE LOW FOR THE
MONTH WAS 49.9 (24TH COLDEST ON RECORD), AND -0.8 DEGREES BELOW THE
49.9 DEGREE NORMAL. SIMILARLY, THE AVERAGE LOW IN SAGINAW WAS 49.9
(39TH COLDEST ON RECORD), AND -0.6 BELOW THE NORMAL OF 50.5 DEGREES.
THE AVERAGE TEMPERATURE FOR THE ENTIRE MONTH OF SEPTEMBER IN FLINT
WAS 61.4 (36TH COLDEST), A DEPARTURE OF +0.3 DEGREES FROM THE 61.1
DEGREE SEPTEMBER NORMAL. FOR SAGINAW, IT WAS 61.2 (50TH COLDEST ON
RECORD), AND -0.1 BELOW THE 61.3 SEPTEMBER NORMAL.
