=====================================================================
   ...UNUSUALLY WARM SUMMER ENDS WITH RECORD RAIN IN SAGINAW...

SUMMER 2012 WILL BE REMEMBERED IN THE FLINT AND SAGINAW AREAS FOR
BEING PARTICULARLY HOT AND DRY. THE SUMMER`S AVERAGE TEMPERATURE OF
71.7 IN FLINT AND 72.0 IN SAGINAW TIED IT FOR THE 13TH AND 5TH
WARMEST SUMMER ON RECORD RESPECTIVELY. THE TEMPERATURE HAS ALSO
REACHED OR EXCEEDED THE 90 DEGREE THRESHOLD ON 29 OCCASIONS FOR THE
CALENDAR YEAR TO DATE IN FLINT AND 22 OCCASIONS IN SAGINAW. ALTHOUGH
BOTH FALL SHORT OF THE RECORDS, THEY ARE BOTH FAR ABOVE THE AVERAGE
AND REAFFIRM THIS SUMMER`S POSITION AMONG THE UPPER TIER OF
UNUSUALLY WARM SEASONS. OVERALL, AUGUST WAS A RELATIVELY QUIET AND
NEAR-NORMAL MONTH WITH THE EXCEPTION OF ONE MOISTURE-LADEN AUTUMN-LIKE
STORM SYSTEM THAT BROUGHT A PERIOD OF EXCEPTIONAL RAINFALL TO THE
SAGINAW VALLEY AREA. AFTER MEASURING 1.10" OF RAIN ON AUGUST 9TH, AN
INCREDIBLE 6.93" FELL OVER THE COURSE OF THE FOLLOWING DAY, NEARLY
ALL OF WHICH WAS STRATIFORM IN NATURE. THE DROUGHT-BUSTING RAIN WAS
THE GREATEST 1-DAY RAINFALL IN SAGINAW`S HISTORICAL RECORD AND THE
2-DAY TOTAL OF 8.03" WAS THE 2ND GREATEST SUCH TOTAL (BEHIND 10.06"
ON 9/11/1986). BY SUMMER`S END, SAGINAW HAD RECORDED 15.67" OF
RAINFALL. WITH OVER HALF OF THE RAIN HAVING FALLEN ON AUGUST 9-10,
SUMMER 2012 NOW DECEPTIVELY RANKS AS THEIR SECOND WETTEST SUMMER ON
RECORD.

THE SECOND WEEK OF AUGUST SAW A QUICK TRANSITION FROM SUMMER TO
AUTUMN WEATHER. THROUGH THE THE BEGINNING OF THE MONTH, TEMPERATURES
HOVERED ABOVE NORMAL, WITH MULTIPLE 90+ DEGREE READINGS BEING
RECORDED IN FLINT ALONG WITH ONE IN SAGINAW DURING THIS TIME. FROM
THERE, HOWEVER, 10 OUT OF THE NEXT 14 DAYS AVERAGED BELOW NORMAL IN
FLINT AND 12 OUT OF 14 IN SAGINAW AS PERSISTENT TROUGHING SETTLED
OVER THE GREAT LAKES. IT WAS DURING THIS TIME THAT THE PATTERN
BECAME MORE ACTIVE AND THE BULK OF THE MONTH`S RAIN WAS OBSERVED
OVER THE AREA. SAGINAW`S MONTHLY RAINFALL TOTAL OF 9.43" WAS A
RECORD FOR AUGUST WHILE FLINT`S 3.16" WAS NORMAL. A WARMER AND MORE
TROPICAL AIRMASS THEN SPREAD INTO THE STATE TO END THE MONTH AS THE
REMNANTS OF HURRICANE ISAAC LIFTED INTO THE OHIO VALLEY.  ALTHOUGH
THIS BROUGHT LITTLE IN THE WAY OF RAIN, THE BOOST TO TEMPERATURES
HELPED LIFT THE AVERAGE TEMPERATURE FOR THE MONTH TO 69.7 IN FLINT
AND 69.3 IN SAGINAW, BOTH OF WHICH WERE +0.9 ABOVE THE AUGUST
AVERAGE. IN WHAT HAS BEEN A THEME FOR MOST OF THE CALENDAR YEAR TO
DATE, SEVERE WEATHER WAS DORMANT AS AUGUST SAW ZERO REPORTS IN THE
THE NWS WHITE LAKE FORECAST AREA.

THE AVERAGE HIGH TEMPERATURE FOR THE FLINT AREA WAS 81.7 (33RD
WARMEST ON RECORD), AND +2.0 DEGREES ABOVE THE NORMAL VALUE OF 79.7.
THE AVERAGE HIGH IN SAGINAW WAS 80.0 (54TH WARMEST ON RECORD), +0.6
DEGREES ABOVE THE 80.0 DEGREE NORMAL. FLINT`S AVERAGE LOW FOR THE
MONTH WAS 57.7 (49TH WARMEST ON RECORD), AND -0.2 BELOW THE 57.9
DEGREE NORMAL. SIMILARLY, THE AVERAGE LOW IN SAGINAW WAS 59.3 (31ST
WARMEST ON RECORD), AND +1.0 ABOVE THE NORMAL OF 58.3 DEGREES. THE
AVERAGE TEMPERATURE FOR THE ENTIRE MONTH OF AUGUST IN FLINT WAS 69.7
(40TH WARMEST), A DEPARTURE OF +0.9 DEGREES FROM THE 68.8 DEGREE
AUGUST NORMAL. FOR SAGINAW, IT WAS 69.3 (39TH WARMEST ON RECORD),
AND ALSO +0.9 DEGREES ABOVE THE 68.8 DEGREE AUGUST NORMAL.
