JUNE 2013 WAS HIGHLIGHTED BY HIGHLY VARIABLE RAINFALL AMOUNTS ALONG
WITH NORMAL TEMPERATURES. ALTHOUGH GRAND RAPIDS...LANSING...AND
MUSKEGON ALL RECORDED ABOVE NORMAL RAINFALL...SOME LOCATIONS ACROSS
CENTRAL LOWER MICHIGAN RECORDED BELOW NORMAL RAINFALL. THE DISPARITY
WAS APPARENT BETWEEN COOP SITES LIKE HART AND SCOTTVILLE WHICH
RECEIVED LESS THAN 1.5 INCHES OF RAIN COMPARED TO THE LANSING
CAPITAL CITY AIRPORT WHICH RECEIVED NEARLY 8.5 INCHES.

THE MONTH GOT OFF TO A RATHER COOL START DURING THE FIRST TWO WEEKS
OR SO WITH HIGHS MAINLY IN THE 60S AND 70S. IT WAS ALSO A WET PERIOD
AT TIMES WITH ALL THREE PRIMARY CLIMATE SITES RECEIVING A ONE INCH
OR MORE RAINFALL EVENT...AND IN THE CASE OF LANSING THERE WERE TWO
EVENTS OVER ONE INCH. A SEVERE WEATHER EVENT LATE ON JUNE 12TH AND
EARLY ON JUNE 13TH BROUGHT DAMAGE TO TREES AND PRODUCED A FEW LARGE
HAIL REPORTS AS WELL AS FLASH FLOODING TO SOUTHWEST LOWER MICHIGAN.
STRONG STORMS ALSO BROUGHT LOCALIZED DAMAGE TO THE VICKSBURG AREA ON
THE 17TH WITH A 68 MPH MEASURED GUST ALONG WITH SOME TREE AND ROAD
SIGN DAMAGE.

PERIODS OF HEAVY RAIN ALSO STRUCK DURING THE SECOND HALF OF THE
MONTH WITH NUMEROUS INSTANCES OF 1 TO 3 INCH RAINFALL TOTALS ACROSS
SOUTHWEST MICHIGAN. REPORTS OF FLOODING OCCURRED IN THE KALAMAZOO
AREA ON THE 25TH WITH 2 TO 4 INCHES OF RAIN FALLING IN A SHORT TIME.
ADDITIONAL SIGNIFICANT RAINFALL STRUCK THE LANSING AREA ON THE 28TH
WITH A BAND OF 1 TO 3 INCHES THAT PRODUCED LOCALIZED FLOODING AND
TEMPORARY BARRICADING OF ROADS.

BY THE END OF THE MONTH...THE LANSING AREA HAD REACHED THE 4TH
WETTEST JUNE ON RECORD AND ALSO THE 9TH WETTEST MONTH ON RECORD.
WITH THE MIDWAY POINT IN THE YEAR FAST APPROACHING...ALL THREE
CLIMATE SITES WERE EASILY ON RECORD PACE FOR THE WETTEST YEAR ALL
TIME. THIS IS ESPECIALLY DUE IN PART TO A WET SPRING FOR MUCH OF
WEST MICHIGAN.
