AUGUST WAS THE DRIEST MONTH OF THE 2008 TO DATE. IT WAS ALSO THE
MONTH WITH THE LEAST NUMBER OF DAYS OF MEASURABLE PRECIPITATION DAYS
IN 2008. AT GRAND RAPIDS THERE WERE ONLY 5 DAYS WITH MEASURABLE
PRECIPITATION. THE LAST TIME GRAND RAPIDS HAD LESS DAYS IN A
CALENDAR MONTH WITH MEASURABLE PRECIPITATION WAS IN SEPTEMBER OF
2004 WHEN THERE WAS ONLY 4 DAYS. AT LANSING THERE WERE 7 DAYS WITH
MEASURABLE PRECIPITATION. THE LAST TIME THE LANSING AREA HAD LESS
DAYS OF MEASURABLE PRECIPITATION IN A CALENDAR MONTH WAS JUNE OF
2006 WHEN THERE WAS 6 DAYS. RAINFALL ACROSS THE AREA WAS FROM 2 TO
3 INCHES BELOW NORMAL. MOST AREA IN THE GRAND RAPIDS COUNTY WARNING
AREA (CWA) HAD LESS THAN ONE AND A HALF INCHES OF RAIN FOR THE
ENTIRE MONTH.
THERE WAS ALSO A LACK OF SEVERE WEATHER ACROSS SOUTHWEST LOWER
MICHIGAN DURING THE MONTH. THE MAIN SEVERE WEATHER EVENT CAME ON THE
7TH WHEN A SERIES OF WATERSPOUTS DEVELOPED OVER LAKE MICHIGAN. THE
WATERSPOUTS OCCURRED OFFSHORE FROM GRAND HAVEN DOWN TO SOUTH HAVEN
DURING THE LATE MORNING AND EARLY AFTERNOON HOURS AS A FRONT DROPPED
THROUGH THE AREA. THE FRONT...COMBINED WITH COOL TEMPERATURES MOVING
OVER THE 70 PLUS DEGREE WATERS OF LAKE MICHIGAN PRODUCED THE
WATERSPOUTS. OTHER THAN THE WATERSPOUTS...ONLY AN ISOLATED SEVERE
EVENT OCCURRED WHEN SOME ISOLATED WIND DAMAGE OCCURRED IN HARRISON
AND ST. JOHNS ON THE 23RD WITH A LINE OF THUNDERSTORMS.
BESIDES BEING A DRY MONTH AUGUST 2008 WAS THE COOLEST AUGUST SINCE
2004. MOST OF SOUTHWEST LOWER MICHIGAN AVERAGED NEAR NORMAL EVEN SO.
THE COOLEST PART OF THE MONTH WAS FROM THE 8TH THROUGH THE 16TH.
DURING THAT TIME NEARLY EVERY DAY WAS COOLER THAN NORMAL ACROSS THE
AREA. THE COLDEST LOW TEMPERATURE WAS 32 DEGREES... WHICH WAS
REPORTED AT BALDWIN ON THE MORNING OF THE 26TH. THE 23RD WAS THE
WARMEST DAY FOR THE MONTH IN MOST AREAS. GRAND RAPIDS AND LANSING
BOTH BRIEFLY WARMED TO 90 DEGREES. BATTLE CREEK HAD THE WARMEST
REPORTED HIGH IN THE AREA FOR AUGUST WITH A HIGH OF 91 DEGREES ON
THE 23RD. SEVERAL LOCATIONS REACHED 90 DEGREES ON THE 31ST...THOSE
WOULD INCLUDE HOLLAND AND WELLSTON.
