AUGUST 2014 WAS A FAIRLY BENIGN MONTH FOR MOST OF SOUTHWEST LOWER
MICHIGAN...WITH NEAR NORMAL TEMPERATURES AND VARIABLE BUT NEAR
NORMAL RAINFALL IN GENERAL.

NO DAILY RECORDS FOR TEMPERATURE OR PRECIPITATION WERE SET
AT THE THREE MAIN CLIMATE SITES. FOR THE FIRST TIME SINCE
2009...AUGUST WAS THE WARMEST MONTH OF METEOROLOGICAL SUMMER...OWING
TO THE WELL BELOW NORMAL JULY. GRAND RAPIDS...LANSING...AND MUSKEGON
FAILED TO REACH 90 DEGREES...WHICH KEPT THE NUMBER OF 90 DEGREE DAYS
FOR EACH SITE AT ZERO FOR THE YEAR TO DATE. IN GRAND RAPIDS...THIS
WAS THE FIRST YEAR SINCE 1951 IN WHICH TEMPERATURES DID NOT REACH 90
DEGREES BY THE END OF AUGUST. IN LANSING...IT WAS THE FIRST YEAR
SINCE 2004. KALAMAZOO AND BATTLE CREEK REACHED OR EXCEEDED THE 90
DEGREE MARK THIS MONTH.

RELATIVELY LOW HUMIDITY THE FIRST THIRD OF THE MONTH ALLOWED FOR
WIDER TEMPERATURE RANGES...WITH AFTERNOON HIGHS REACHING NEAR TO
ABOVE NORMAL BUT MORNING LOWS USUALLY FALLING BELOW NORMAL. THERE
WAS A COOL DOWN AROUND THE MIDDLE OF THE MONTH. GRAND RAPIDS FAILED
TO REACH 70 DEGREES ON AUGUST 12TH AS DID MUSKEGON ON THE 12TH AND
14TH. GRAND RAPIDS...MUSKEGON...AND LANSING ALSO EXPERIENCED AT
LEAST ONE MORNING WITH TEMPERATURES IN THE 40S. HIGH HUMIDITY AND
WARMER TEMPERATURES THEN RULED THE LATTER THIRD OF THE MONTH. HIGHS
CONSISTENTLY REACHED THE UPPER 70S AND LOW 80S...NEAR NORMAL...WHILE
LOWS OFTEN STAYED ABOVE NORMAL IN THE MID TO UPPER 60S.
OVERALL...AVERAGE TEMPERATURES FOR THE MONTH WERE WITHIN ONE DEGREE
OF NORMAL FOR MOST LOCATIONS...THOUGH WERE GENERALLY ON THE COOLER
SIDE OF NORMAL.

RAINFALL WAS MORE PLENTIFUL IN THE EASTERN PART OF THE STATE THAN IT
WAS IN THE WESTERN PART. RAINFALL WAS USUALLY DELIVERED IN HEAVY
BATCHES IN ASSOCIATION WITH SHOWERS AND THUNDERSTORMS AS IS TYPICAL
FOR LATE SUMMER...AND AS SUCH...LOCAL DEPARTURES FROM NORMAL CAN BE
QUITE VARIABLE. IN GENERAL...THE LANSING AREA AND THE LAKESHORE
SOUTH OF HOLLAND WERE MODESTLY ABOVE NORMAL. GRAND RAPIDS ENDED UP
RIGHT NEAR NORMAL. KALAMAZOO...BATTLE CREEK...AND JACKSON WERE
MODESTLY TO MODERATELY BELOW NORMAL. THE LEAST AMOUNT OF RAIN FELL
IN WEST CENTRAL AND NORTHWEST LOWER MICHIGAN...WHERE LESS THAN 75
PERCENT OF NORMAL RAINFALL WAS RECEIVED.

THERE WERE A FEW EPISODES OF LOCALLY SEVERE WEATHER BUT WIDESPREAD
SIGNIFICANT SEVERE WEATHER DID NOT OCCUR. THE BIGGEST EVENT ON
AUGUST 19 PRODUCED A LINE AND CLUSTER OF STORMS WHICH PROGRESSED
THROUGH SOUTHERN LOWER MICHIGAN. THERE WERE MULTIPLE REPORTS OF
DOWNED TREES IN ALLEGAN AND VAN BUREN COUNTIES...AND A GUST OF 68
MPH WAS MEASURED AT THE SOUTH HAVEN LIGHT.
