JUNE 2016 ENDED SLIGHTLY WARMER THAN NORMAL FOR SOUTHERN LOWER MICHIGAN...WHILE
THE REMAINDER OF THE LOWER PENINSULA HOVERED NEAR NORMAL. THE MAIN HEADLINE
TURNED OUT TO BE THE DRY PATTERN...WHICH PLACED MUCH OF THE SOUTHEASTERN CORNER
OF THE SATE IN ABNORMALLY DRY STATUS AS THE MONTH DREW TO A CLOSE.

A MAJORITY OF THE MONTH RESULTED IN DAILY TEMPERATURES THAT WERE FAIRLY
COMFORTABLE BY LATE-SPRING AND EARLY-SUMMER STANDARDS. NEAR 90 DEGREE
TEMPERATURES WERE OFTEN OFFSET BY DAYS WHEN TEMPERATURES WERE NEAR OR BELOW 80
DEGREES. EVEN IN INSTANCES WHEN TEMPERATURES REACHED OR EXCEEDED THE 90 DEGREE
BENCHMARK...IT WAS HARD TO COME BY HIGH MOISTURE LEVELS. THIS LIMITED THE
NUMBER OF MUGGY DAYS...WHILE ALSO ALLOWING COOLER NIGHTS TO SETTLE IN FROM TIME
TO TIME. ON A FEW OCCASIONS...TEMPERATURES FELL WELL INTO THE 40S WITH
OUTLYING RURAL AREAS FALLING INTO THE UPPER 30S.

AS MENTIONED...THE LACK OF MOISTURE SLOWLY RAISED CONCERNS AS JUNE PROGRESSED.
FEW INSTANCES INCLUDED HIGHER RAINFALL TOTALS. WHEN HIGHER RAINFALL AMOUNTS DID
FALL...THE EVENTS WERE RATHER QUICK...LOCALIZED AND LARGELY CONFINED TO THE
FIRST HALF OF THE MONTH. BEYOND JUNE 15TH...MEASURABLE PRECIPITATION WAS
EXTREMELY SPARSE...ESPECIALLY ACROSS CENTRAL AND SOUTHEASTERN LOWER MICHIGAN. A
LARGE NUMBER OF COMMUNITIES BEGAN TO PROHIBIT BURNING...AS SOILS DRIED AND
VEGETATION BEGAN TO SHOW SIGNS OF THE ONSET OF DROUGHT. AT THE END OF THE
MONTH...SOME PLACES DID NOT EVEN REACH ONE-QUARTER OF THEIR NORMAL MONTHLY
PRECIPITATION.

DRY WEATHER WOULD PROVE TO BE WORTHY ENOUGH TO RANK 2016 AS THE 3RD DRIEST JUNE
ON RECORD FOR LANSING AND 10TH DRIEST JUNE ON RECORD FOR GRAND RAPIDS. MUSKEGON
WAS THE LONE CLIMATE SITE TO RECEIVE NEAR NORMAL RAINFALL WITH A DEFICIT OF
ONLY 0.21 OF AN INCH. ABOUT ONE-THIRD OF THE PRECIPITATION CAME IN ONE EVEN ON
JUNE 15TH. THE EVENT ALSO RESULTED IN SEVERE THUNDERSTORM WIND GUSTS THAT
BROUGHT DOWN SEVERAL TREES AND POWER LINE IN AREAS SURROUNDING MUSKEGON. SOME
RESIDENTS WENT A FEW DAYS BEFORE POWER WAS RESTORED. OTHERWISE...SEVERE WEATHER
WAS FAIRLY TAME AND SCATTERED THROUGH THE MONTH.
