TEMPERATURES IN AUGUST 2015 WERE NEAR TO SLIGHTLY BELOW NORMAL. AS
IS OFTEN THE CASE DURING SUMMER MONTHS...RAINFALL DUE TO
THUNDERSTORMS VARIED SIGNIFICANTLY BY LOCATION. LANSING RECORDED ITS
THIRD WETTEST AUGUST WITH 6.82 INCHES. RECORDS GO BACK TO 1863.
LANSING ALSO RECORDED ITS WETTEST AUGUST DAY WITH 3.77 INCHES ON
AUGUST 10...BREAKING THE OLD RECORD OF 3.39 INCHES SET ON AUGUST 27
2013. AUGUST 10 2015 IS NOW THE 6TH WETTEST CALENDAR DAY ON RECORD
AT LANSING.

TEMPERATURES WERE NEAR NORMAL TO A LITTLE ON THE COOL SIDE OF NORMAL
DURING AUGUST 2015. HIGHS IN THE UPPER 70S AND 80S WERE COMMON IN
THE EARLY AND MIDDLE PARTS OF THE MONTH...WITH A COOL DOWN DURING
THE LAST WEEK OF THE MONTH WITH HIGHS IN THE 60S FOR A FEW DAYS.
MOST LOCATIONS REACHED 90 DEGREES ONE TIME. MUSKEGON AND JACKSON DID
NOT HAVE A 90 DEGREE DAY.

AUGUST GOT OFF TO A QUICK START WITH ACTIVE WEATHER AS A LINE OF
STRONG TO SEVERE THUNDERSTORMS MOVED SOUTH THROUGH LOWER MICHIGAN
DURING THE EVENING HOURS OF AUGUST 2ND 2015. THOUGH THE STORMS
PRODUCED DESTRUCTIVE WINDS AND BASEBALL SIZE HAIL IN NORTHERN LOWER
MICHIGAN...THE MAIN EFFECTS OF THESE STORMS IN CENTRAL TO SOUTHERN
MICHIGAN WERE 40-50 MPH WINDS WITH SOME LOCALLY HIGHER GUSTS.
LOCALLY HEAVY RAINFALL...SMALL HAIL...AND VERY FREQUENT LIGHTNING
WERE ALSO COMMON. RESULTING IMPACTS INCLUDED SOME POWER OUTAGES AND
BROKEN TREE BRANCHES AS WELL AS A FEW TREES THAT CAME DOWN AND
CAUSED DAMAGE.

PERIODS OF RAIN WITH SCATTERED THUNDERSTORMS RETURNED TO THE AREA ON
MONDAY AUGUST 10. GRAND RAPIDS RECEIVED 1.22 INCHES...BUT MANY
LOCATIONS DID NOT RECEIVE SIGNIFICANT AMOUNTS OF RAIN.
HOWEVER...STORMS WITH OVER 1 INCH PER HOUR RAINFALL RATES PERSISTED
NEAR ROCKFORD AND LANSING...LEADING TO HIGHER TOTALS. AREAS BETWEEN
PORTLAND AND LANSING RECEIVED 2.5 TO 4.5 INCHES. MODERATE STREET
FLOODING AND PONDING OF WATER WAS COMMON IN LANSING. ROADS IN SOME
LOW SPOTS HAD WATER LEVELS APPROACHING THE ROOFS OF CARS. US-127
NEAR SAGINAW HWY WAS SHUT DOWN FOR HOURS DUE TO DEEP FLOODWATERS AND
CLOGGED STORM DRAINS.
