==================================================================
CLIMATOLOGICAL SUMMARY FOR FLINT/SAGINAW - JULY 2009
...COLDEST JULY ON RECORD FOR BOTH FLINT AND SAGINAW...
...EVEN THOUGH SLIGHTLY COLDER THAN 1992 THIS JULY STILL NICER...
...SEVERE WEATHER NEARLY NON-EXISTENT FOR AN USUALLY ACTIVE MONTH...
...SOME AREAS BEGIN TO DRY OUT DURING THE MONTH...
***DOMINANT TEMPERATURE/RAIN TREND...BELOW NORMAL/BELOW NORMAL***
THERE HAS NOT BEEN A JULY THIS COOL (OR COMFORTABLE FOR THAT MATTER)
SINCE ALL OFFICIAL RECORD KEEPING FOR BOTH FLINT /1921/ AND SAGINAW
/1900/. BOTH FLINT...WITH AN AVERAGE JULY TEMPERATURE OF 65.6 AND
SAGINAW WITH AN AVERAGE OF 66.0...BEAT OUT THE SOMEWHAT RECENT
PREVIOUS COLDEST JULY OF 1992 /FNT-66.9 AND MBS-66.2/ BY TWO OR
THREE TENTHS. EVEN DETROIT WITH ITS MORE EXPANSIVE HEAT ISLAND
CAME IN THIRD PLACE WITH 68.9 /68.8-1992/. THE "UP NORTH" WEATHER
VACATIONED DOWN HERE IN THE SOUTH WITH THE MONTH`S WEATHER WAS MORE IN
LINE WITH THE TIP OF LOWER MICHIGAN. WHILE ABNORMALLY COOL THERE WAS
PLENTY OF SUNSHINE FOR MOST ACROSS SOUTHEAST LOWER MICHIGAN (THOUGH
HOT WEATHER INTERESTS MAY DISAGREE). NORMALLY IN JULY...WE SEE ABOUT
HALF OUR 90S /3-4/ FOR THE SUMMER /8/ AND THIS JULY WE COULDN`T EVEN
MUSTER AN 85! BOTH CITIES RECORDED AN 84 ON THE 28TH AS THEIR
HIGHEST TEMPERATURE FOR JULY. THIS WAS NOT THE LOWEST HIGH HOWEVER
FOR A JULY IN FLINT`S HISTORY...IN 1992 THE HIGHEST FOR THE MONTH
ONLY REACHED 83 ON THE 1ST. IN ADDITION...THE MONTH ITSELF WAS NOT
ONLY COOL IT WAS VERY WET WITH OVER NINE INCHES OF RAIN /9.35"/
FALLING. SO COMPARING THE TWO...EVEN THOUGH JULY 2009 WAS COLDER BY
A FEW TENTHS...JULY 1992 WAS NOT ONLY A RECORD COOL MONTH IT WAS
MISERABLY WET...SO WORSE THAT THIS JULY ON THE WHOLE. ROUGHLY THE
SAME COULD BE SAID ABOUT SAGINAW...IN 1992 THE HIGH ONLY REACHED 83
TWICE AND 4.25 RAIN FELL.
NEARLY EVERY DAY IN THE MONTH AVERAGED BELOW NORMAL IN JULY (ONLY
ONE AVERAGED ABOVE NORMAL). ACTUALLY...THE ENTIRE FIRST THREE WEEKS
OF JULY WERE THE COLDEST WITH TEMPERATURES AVERAGING AROUND SIX
DEGREES BELOW NORMAL. THE COLDEST DAYS WERE ON THE 7TH AND 17TH WHEN
THE TEMPERATURE STRUGGLED TO MAKE EVEN 70 DEGREES /KEEP IN MIND THE
AVERAGE IS LOWER TO MID MID 80S/. BOTH SAGINAW AND FLINT HAD A HIGH
AMOUNT OF HEATING DEGREE DAYS AND VERY LOW AMOUNT OF COOLING DEGREE
DAYS (VERSUS THE NORM). IN FACT...HERE AT WHITE LAKE /NWS/ OUR
COOLING DEGREE DAYS VERSUS HEATING DEGREE DAYS FOR THE NWS IN WHITE
LAKE...THEY ARE THE SAME /55/...HIGHLY UNUSUAL FOR JULY.
AFTER SEVERAL DOMINANT WET MONTHS...JULY BEGAN SHOWING SIGNS OF
"DRYING TREND". THE DRIER WEATHER DEVELOPED IN POCKETS ACROSS
SOUTHEAST LOWER MICHIGAN BUT WHETHER ITS A TREND OR JUST SHORT-LIVED
REMAINS TO BE SEEN. THERE ALSO WAS LITTLE IN THE WAY OF SEVERE
WEATHER WITH JUST AN ISOLATED CASE OR TWO...NOT TYPICAL FOR JULY.
