JULY 2016 CAME TO A CLOSE WITH TEMPERATURES THAT AVERAGED SLIGHTLY ABOVE NORMAL
THROUGH MOST OF CENTRAL LOWER MICHIGAN AND NEAR NORMAL IN FAR SOUTHWEST LOWER
MICHIGAN. AREA-WIDE PRECIPITATION TOTALS AVERAGED ABOVE NORMAL WITH SPORADIC
LOCATIONS WELL ABOVE OR BELOW NORMAL.

IT WAS A MILD MONTH OVERALL. LESS THAN ONE-THIRD OF THE DAYS RESULTED IN
TEMPERATURES THAT WOULD BE CONSIDERED BELOW NORMAL. ABOUT HALF OF THE BELOW
NORMAL DAILY AVERAGES WERE CONFINED TO THE FIRST WEEK. MUCH OF THE TIME...HIGH
TEMPERATURES AT EACH CLIMATE SITE WERE SOLIDLY IN THE 80S WITH FEW 90S
INTERSPERSED THROUGHOUT JULY. NO RECORD HIGH TEMPERATURES WERE SET...BUT
RELATIVELY WARM NIGHTS WERE COMMON. LANSING TIED A RECORD WARM LOW TEMPERATURE
OF 73 DEGREES ON JULY 22ND...PREVIOUSLY SET IN 1972. ELEVATED HUMIDITY LEVELS
PERIODICALLY MADE THEIR WAY INTO THE LOWER PENINSULA. THE COMBINATION OF WARM
TEMPERATURES AND MOISTURE LED TO A FEW SULTRY SUMMER DAYS.

PRECIPITATION...WHILE NOT AT ALL VOID...WAS HIT-OR-MISS. THE CONVECTIVE
ENVIRONMENT PROVIDED FOR LOCALIZED HEAVY RAINFALL. A BULK OF THE MONTHS
MOISTURE WAS RECEIVED IN LARGE...SINGLE EVENTS. AS HIGH PRESSURE STRENGTHENED
AND MEANDERED THROUGH THE MIDWEST...THE ACTIVE STORM TRACK SET UP OVER THE
GREAT LAKES REGION FROM TIME TO TIME. ON JULY 7TH...LOCALIZED HEAVY RAIN
DEVELOPED OVER JACKSON MICHIGAN...LEADING TO URBAN FLOODING THAT AFFECTED THE
GROUND FLOOR OF THE HENRY FORD ALLEGIANCE HEALTH HOSPITAL. ON JULY 24TH AND
JULY 29TH...THE MUSKEGON AND GRAND RAPIDS AREAS RECEIVED THEIR FAIR SHARE OF
RAINFALL. BOTH SITES BROKE DAILY RAINFALL RECORDS ON JULY 24TH...WITH 2.93
INCHES OF RAIN RECORDED IN MUSKEGON AND 1.53 INCHES RECORDED IN GRAND RAPIDS.
MUSKEGONS MONTHLY RAINFALL RANKED 5TH WETTEST ON RECORD.

SEVERE WEATHER WAS FAIRLY TAME WITH A LIMITED NUMBER OF LOCAL STORM REPORTS.
ONLY MARGINAL STORM DAMAGE WAS PERIODICALLY NOTED IN JULY. DAMAGE THAT DID
OCCUR WAS LARGELY RELATED TO GUSTY WINDS AND CONSISTED OF FEW DOWNED
TREES...LIMBS AND POWERLINES ON A LOCAL SCALE. NO WIDESPREAD SEVERE WEATHER
DEVELOPED THROUGHOUT THE MONTH.
