CLIMATOLOGICAL SUMMARY FOR DETROIT - JUNE 2009
...SUMMER STARTS OUT COOL AND WET /13TH WETTEST/ ACROSS THE REGION...
...SEVERE WEATHER AND TORRENTIAL RAINS CAUSE DAMAGE AND FLOODING...
***DOMINANT TEMPERATURE/RAIN TREND...BELOW NORMAL/ABOVE NORMAL***
AFTER A RELATIVELY CALM MAY (BUT WET SPRING)...JUNE GOT BUSY AGAIN WITH
OCCASIONAL STORMS AND HEAVY RAINS. THE HEAVY RAINS ONLY EXASPERATED THE
WET GROUND FROM THE WINTER AND SPRING. TOTAL RAINFALL OF 5.28" AT
DETROIT METRO AIRPORT MADE IT THE 13TH WETTEST JUNE SINCE 1870. OTHER
HIGHER TOTALS FOR JUNE INCLUDE...6.71" AT ANN ARBOR AND 6.85 AT
CHELSEA. ALSO...AS OF THE END OF JUNE...MANY AREAS ACROSS SOUTHEAST
LOWER MICHIGAN SAW RAINFALL AMOUNTS OF FOUR TO AS MUCH AS SIX INCHES
ABOVE THE NORM FOR THE FIRST SIX MONTHS OF THE YEAR.
SEVERE WEATHER VISITED OCCASIONALLY DURING THE MONTH WITH THE BEST
EVENTS BEING; ONE FOR HEAVY RAIN ON THE 19-20TH AND THE OTHER FOR
SEVERE STORMS WITH WIND AND HAIL DAMAGE ON THE 25TH. FIRST OFF...
IMPRESSIVE WIDESPREAD TORRENTIAL RAINS ACCOMPANIED STORMS THAT MOVED
OVER THE REGION LATE ON THE 19TH INTO EARLY MORNING HOURS OF THE 20TH
CAUSING LOWLAND AND RIVER FLOODING. SOME OF THE HIGHER (AND AGAIN...
WIDESPREAD) AMOUNTS OF RAINFALL (AND SOME THAT FELL IN LESS THAN 24
HOURS) INCLUDED OVER THREE AND A HALF INCHES /3.59"/ THAT DROWNED THE
BELLEVILLE AREA (SOUTHWEST OF DETROIT)...WHILE 3.40" DELUGED PORTIONS
OF ALLEN PARK. IN ADDITION... 3.48" CLOBBERED DOWNTOWN ANN ARBOR...
2.90" FILLED THE RAIN BUCKETS IN CANTON AND GROSSE POINTE...2.85" OF
RAIN WAS DUMPED JUST WEST OF THE TOWN OF PLYMOUTH...2.40" AT BOTH
PINCKNEY AND MONROE...2.35 NEAR ROCKWOOD... 2.28" AT WOODHAVEN AND
2.16" IN HOWELL.
THEN LATER IN THE WEEK ON THE 25TH...SEVERE WEATHER ROCKED THE AREA
WITH MANY REPORTS OF WIND GUSTS BETWEEN 60 AND 75 MPH ACROSS THE REGION
(ESPECIALLY THE NORTH-NORTHEAST SUBURBS). MACOMB COUNTY SAW THE WORST OF
THE WINDSTORM DAMAGE. A 75 MPH WIND GUST ESTIMATED AT FRASER RESULTED
IN NUMEROUS TREES AND POWER LINES KNOCKED DOWN. ALSO...A 75 MPH WIND
GUST AT MACOMB TWP BROUGHT DOWN LARGE TREE LIMBS AND A FLAG POLE. IN
ADDITION...70 MPH WINDS IN ST CLAIR SHORES AND SHELBY TWP SAW CAUSED
CONSIDERABLE DAMAGE TO TREES WITH SOME BRANCHES/TREES BLOCKING ROADS.
POWERFUL WINDS OF 65 MPH UPROOTED A COUPLE OF TREES AND SLAMMED THEM
ONTO ROOFS OF HOMES IN STERLING HEIGHTS...WHILE UP TO GOLFBALL SIZE HAIL
POUNDED THE OXFORD/LAKE ORION AREA WITH LOCALIZED DAMAGED TO VEHICLES.
BESIDES THE WETNESS...THE OTHER MAIN TREND OF THE MONTH WAS THE
COOLNESS (OR BELOW NORMAL TEMPERATURES)...MAINLY THE FIRST HALF OF THE
MONTH. FROM THE 1ST THROUGH THE 16TH...TEMPERATURES AVERAGED AROUND 60
TO THE LOWER 60S...OR 4 TO 6 DEGREES BELOW NORMAL BY THAT POINT. IF
THOSE AVERAGES HAD CONTINUED...MUCH OF SOUTHEAST MICHIGAN WOULD HAVE
EXPERIENCED ITS COLDEST JUNE ON RECORD. FORTUNATELY (AND SOMEWHAT
IRONICALLY)...TEMPERATURES WARMED JUST IN TIME FOR THE CALENDAR
BEGINNING /21ST/ OF SUMMER. A WARM STRETCH OF WEATHER IN THE 80S AND
EVEN A COUPLE OF 90S /92 ON THE 24-25TH/ ERASED MUCH OF THAT COLD BELOW
NORMAL DEPARTURE ACCUMULATED THE FIRST HALF OF THE MONTH. TEMPERATURE
DEPARTURES BY THE END OF THE MONTH ENDED UP BEING JUST ABOUT A DEGREE
AND A HALF BELOW NORMAL.
