JUNE 2017 TEMPERATURES LARGELY AVERAGED ABOVE NORMAL THROUGH MUCH OF
LOWER MICHIGAN. PRECIPITATION VARIED BETWEEN GREATER THAN NORMAL
RAINFALL OVER CENTRAL LOWER MICHIGAN AND BELOW NORMAL RAINFALL OVER
PORTIONS OF SOUTHERN LOWER MICHIGAN. THUNDERSTORMS HAD LOCALIZED
IMPACTS ON MONTHLY TALLIES, WHICH MAY NOT BE AS ACCURATELY REFLECTED
IN GENERAL GRAPHICS.

MUCH OF LOWER MICHIGAN`S TEMPERATURE DEPARTURES AVERAGED 1-2 DEGREES
ABOVE NORMAL. DEPARTURES WERE AFFECTED BY THE LOCALIZED VARIATIONS
IN EVENT-DRIVEN PRECIPITATION AMOUNTS AND EVENT FREQUENCY. LANSING`S
CAPITAL REGION INTERNATIONAL AIRPORT TIED (1934) ITS 5TH WARMEST
JUNE ON RECORD WITH A MONTHLY TEMPERATURE AVERAGE OF 71.1 DEGREES.
THIS WAS 3.5 DEGREES WARMER THAN NORMAL. THE WARMEST JUNE ON RECORD
OCCURRED IN 2005, WHEN AN AVERAGE OF 72.7 DEGREES WAS RECORDED.

THE HOTTEST PART OF THE MONTH SPANNED A 5 DAY PERIOD FROM JUNE 10TH
THROUGH JUNE 14TH. HIGH TEMPERATURES CONSISTENTLY RANGED FROM THE
UPPER 80S TO MID-90S THROUGH SOUTHWEST MICHIGAN. THUNDERSTORMS
BROUGHT HEAVY RAIN TO THE AREA ON JUNE 17TH WITH AMOUNTS GENERALLY
UP TO 2 INCHES. LOCALIZED AMOUNTS RANGED FROM 3-4 INCHES. A FEW
THUNDERSTORM EVENTS RESULTED IN LOCALIZED WIND DAMAGE WITH NO
WIDESPREAD HAIL OR WIND EVENTS TO RECALL.

THE BIGGEST STORY OF THE MONTH OCCURRED NEAR AND AROUND MT.
PLEASANT, WHERE SEVERAL INCHES OF RAIN FELL ON THE NIGHT OF JUNE
22ND INTO THE EARLY MORNING HOURS OF JUNE 23RD. MANY ROADS WERE
REPORTED WASHED OUT OR CLOSED. SOME RESIDENTIAL AREAS ACCUMULATED
ENOUGH WATER TO REACH THE HOODS OF VEHICLES. LOCAL IMPACTS WERE
GREAT ENOUGH TO REQUIRE SEVERAL DAYS IN RECOVERY EFFORTS.
