==================================================================
CLIMATOLOGICAL SUMMARY FOR FLINT/SAGINAW - SEPTEMBER 2009
...A RELATIVELY WARM...NICE AND DRY SEPTEMBER BEGINS AUTUMN 2009...
...10TH DRIEST ON RECORD AT BOTH FLINT AND SAGINAW...
***DOMINANT TEMPERATURE/RAIN TREND...ABOVE NORMAL/WELL BELOW NORMAL***
IF MOTHER NATURE WAS TRYING TO MAKE UP FOR THE UNUSUALLY COOL (AND
IN PLACES WET) SUMMER...THEN SEPTEMBER`S WEATHER WAS A GOOD START.
WHILE TEMPERATURES THE FIRST FEW DAYS AND LAST FEW DAYS OF SEPTEMBER
AVERAGED BELOW NORMAL...MUCH OF THE REMAINDER OF THE MONTH SAW
READINGS AVERAGING ABOVE THE NORMAL. RAINFALL FOR THE ENTIRE MONTH
WAS LIGHT WITH JUST OVER AN INCH FALLING AT MOST LOCATIONS ACROSS
THE SAGINAW VALLEY AND THUMB REGION. THIS MADE IT THE TENTH DRIEST
ACROSS THE REGION SINCE RECORDS BEGAN /FLINT 1921 AND SAGINAW 1898/.
THE MOST IMPRESSIVE TIME SLOT FOR THE DRY WEATHER STARTED ON THE 1ST
AND WENT THROUGH THE 20TH WHEN MOST AREAS HAD INCONSEQUENTIAL
RAINFALL AMOUNTS WITH JUST A HUNDREDTH OR TWO. THEN EVEN ON THE
21ST...JUST A THIRD OF AN INCH OF RAIN FELL OVER THE REGION.
THE WARMEST TEMPERATURES OF THE MONTH NATURALLY OCCURRED DURING THE
FIRST HALF OF THE MONTH...ESPECIALLY FROM THE 13TH THROUGH THE 15TH
WHEN READINGS POPPED UP INTO THE LOWER 80S. THE LATTER THIRD OF THE
MONTH BECAME A LITTLE WETTER BUT REMAINED PRIMARILY WARM UNTIL...AS
MENTIONED...THE LAST COUPLE OF DAYS. A MINI WARM-UP STARTED UP NEAR
THE FALL EQUINOX AND CARRIED THROUGH THE 24TH WITH READINGS AGAIN
NEAR 80. AT THE MONTH`S CLOSE...THE MONTHLY TEMPERATURE AVERAGED
RIGHT AROUND 62 DEGREES WHICH STILL WAS A DEGREE OR TWO ABOVE NORMAL.
(THE SOUTHEAST LOWER MICHIGAN SUMMER AVERAGE WAS 67.2 DEGREES).
A SHARP COLD FRONT SLICED THROUGH THE REGION LATE IN THE MONTH
/28TH/ AND BROUGHT MUCH COLDER WEATHER (REMINDING US WHAT SEASON HAD
JUST STARTED). SCATTERED EARLY MORNING THUNDERSTORMS ACCOMPANIED THE
FRONT AND THEN LATER...STRONG NORTHWEST WINDS...HEAVY SHOWERS AND
SOME SMALL HAIL FOLLOWED WITH THE COLDER AIR IN PLACE. FLINT BISHOP
AIRPORT REPORTED A WIND GUST OF 47 MPH WHILE SAGINAW`S WIND GUSTED
TO 44 MPH. WIND GUSTS OF 40-50 MPH WERE REPORTED OVER THE SOUTHERN
LAKES. THIS FRESH BLAST OF COLD AIR BROUGHT THE FIRST TRUE AUTUMN
FEEL TO THE AIR BY THE 30TH WITH HIGHS ONLY RISING INTO THE 50S.
