==================================================================
CLIMATOLOGICAL SUMMARY FOR FLINT/SAGINAW - AUGUST 2009
...FINALLY A NEAR NORMAL SUMMER MONTH...COOLS BELOW NORMAL BY THE END...
...TROPICAL-LIKE DOWNPOURS ON THE 8TH BRING LOCALIZED FLOODING...
...VERY HEAVY RAINS IN FLINT LEAD TO THE 5TH WETTEST AUGUST...
...COOL AND WET AUGUST IS A PROPER SEND OFF FOR THE SUMMER...
***DOMINANT TEMPERATURE/RAIN TREND...NORMAL/ABOVE NORMAL***
AFTER WEEKS OF UNSEASONABLY COOL WEATHER THIS SUMMER...TEMPERATURES IN
AUGUST WARMED UP CLOSER TO NORMAL (BUT FELL BELOW IN THE END). WHILE
THE FIRST WEEK STARTED OUT BELOW NORMAL LIKE JULY...TEMPERATURES WARMED
UP CLOSER TO NORMAL AND ABOVE AND HELD THERE DURING THE HEART OF
AUGUST. IN ADDITION... ALTERNATING VERY WET AND DRY PERIODS THAT
STARTED IN JULY PERSISTED IN EARLY AUGUST BUT THEN FADED...AS THE
FREQUENCY OF RAIN PICKED UP THE SECOND HALF.
THE MOST EVENTFUL WEATHER ITEM OF THE MONTH PROCEEDED A STRONG
WARM FRONT THAT PUSHED NORTH THROUGH THE REGION ON THE 8TH. STRONG
THUNDERSTORMS WITH INTENSE RAIN BROUGHT TORRENTIAL RAINS ACROSS
PORTIONS OF THE REGION. AT FLINT...3.89" OF RAIN FELL AT BISHOP AIRPORT
IN THE 24 HOUR PERIOD. INTERESTINGLY...THAT 3.89" OF RAIN DID NOT BREAK
THE DAILY RAIN RECORD FOR THE 8TH WHICH IS 4.50" IN 1937. THE TROPICAL-
LIKE RAINS BROUGHT HIGHER RAINFALL TOTALS TO THE LAPEER REGION WHICH
PROMPTED FLOOD WARNINGS. OUR COOPERATE WEATHER OBSERVER (JUST WEST OF
LAPEER) RECORDED JUST UNDER FIVE INCHES /4.97"/ OF RAIN IN THE 24 HOUR
STRETCH...WHILE GOODRICH /GENESEE COUNTY/ CAME IN AT 4.65". MORE VERY
HEAVY RAINS (WELL OVER THREE INCHES) FELL AT CORUNNA /3.41/...DURAND
/3.49/ AND OWOSSO /3.38/ ALL IN SHIAWASSEE COUNTY.
THE ONLY NOTABLE SEVERE WEATHER EVENT OF AUGUST (ABEIT MINOR) CAME ON
THE HEELS OF THE HEAVY RAINS ON THE 9TH WHEN A LINE OF STORMS BLEW
THROUGH THE REGION AFTER ONE OF THE FEW HOT HUMID DAYS IN AUGUST (AND
THE SUMMER). SCATTERED STORMS BROUGHT DAMAGING WINDS WITH REPORTS OF
SOME TREE DAMAGE
THE LAST THIRD OF THE MONTH REVERTED BACK TO THE FAMILIAR BELOW NORMAL
TEMPERATURE REGIME COOL...RAINY WEATHER DOMINATED THE LAST FEW WEEKENDS
IN AUGUST WITH A SOME HIGH TEMPERATURES MAKING A PITIFUL SHOWING IN THE
60S. AT FLINT FOR EXAMPLE...THE HIGH OF 64 ON THE 22ND AND 62 ON THE
28TH WERE THE COLDEST HIGH TEMPERATURES EVER SEEN FOR THE DATES. AT
SAGINAW...THE MERCURY JUST MADE IT OUT OF THE 50S ON THE 28TH...TOPPING
OUT AT 60. TO ADD INSULT TO INJURY...MUCH OF THIS COOL...DREARY CLOUDY
FALL-LIKE WEATHER CAME ALONG ON THE LAST FEW WEEKENDS OF AUGUST.
THE HEAVY RAINS DURING THE MONTH MADE AUGUST OF 2009 THE 5TH WETTEST ON
RECORD WHILE SAGINAW MISSED THE HEAVIEST OF RAINS AND ACTUALLY ENDED
BELOW THE NORMAL WITH 2.78 /-0.60/. THE COOL WET WEATHER WAS INDEED A
PROPER SEND OFF TO THE SUMMER OF 2009.
LOOK FOR THE COOL SUMMER 2009 WRITE-UP ALONG WITH THE AUTUMN OUTLOOK ON
THE WEB THIS FIRST WEEK OF SEPTEMBER.
