=====================================================================
...RECORD WARM SPRING 2012 FOLLOWED BY DETROIT`S 9TH WARMEST JUNE...

AFTER RECORDING 13 STRAIGHT MONTHS OF ABOVE NORMAL TEMPERATURES, IT
SEEMED LIKE CHANGE MIGHT BE IN THE AIR TO START SEASON. A
WELL-DEVELOPED WINTER-LIKE SYSTEM TRACKED ACROSS SOUTHEAST MICHIGAN
ON THE FIRST DAY OF METEOROLOGICAL SUMMER. THE STORM BROUGHT
WIDESPREAD STRATIFORM RAINFALL AND UNSEASONABLY CHILLY TEMPERATURES.
HIGH TEMPERATURES ON JUNE 1ST WERE 62, 56, AND 54 IN DETROIT, FLINT,
AND SAGINAW RESPECTIVELY. FACTORING IN THE CLOUDS, RAIN, AND WIND IT
FELT EVEN COLDER THAN THAT. HOWEVER, A WEEK OF NORMAL TO SLIGHTLY
BELOW NORMAL TEMPERATURES IN THE 70S AND LOW 80S GAVE WAY TO A
BUILDING UPPER RIDGE THAT INFLUENCED THE WEATHER FOR THE FINAL THREE
WEEKS OF THE MONTH. AS DROUGHT BUILT ACROSS THE CENTRAL UNITED
STATES, HOT AND DRY CONDITIONS INEVITABLY SPREAD INTO THE DETROIT
AREA.

THE FIRST 90 DEGREE TEMPERATURE OF JUNE, AND 3RD OF THE YEAR,
OCCURRED ON THE 9TH DAY OF THE MONTH. HOWEVER, BY THE TIME THE MONTH
WOULD END, THE 90 DEGREE THRESHOLD WOULD ALREADY BE ECLIPSED ON NINE
OCCASIONS (YIELDING A TOTAL OF 11 FOR THE YEAR). THIS IS REMARKABLE
GIVEN THAT THE DETROIT AREA AVERAGES ONLY 11 FOR THE ENTIRE CALENDAR
YEAR. THE AGGRESSIVE RESURGENCE OF WARM WEATHER ALSO RESULTED IN AN
AVERAGE TEMPERATURE OF 50.3 DEGREES FOR THE FIRST HALF OF THE YEAR
(JANUARY 1ST THROUGH JUNE 30TH), THE WARMEST IN THE DETROIT AREA`S
CLIMATE RECORD. THE PREVIOUS RECORD FOR THE FIRST SIX MONTHS OF THE
YEAR WAS 49.1, WHICH BELONGED TO THE NOTORIOUS "SUPER NINO" YEAR OF
1998. WITH ANOTHER HEATWAVE SETTLING IN TO ROUND OUT THE LAST FEW
DAYS OF THE MONTH, DETROIT HIT ITS WARMEST TEMPERATURE OF 99 DEGREES
ON JUNE 28TH. OVERALL, THE AVERAGE TEMPERATURE FOR THE MONTH WAS
72.3, OR +2.9 DEGREES ABOVE THE 69.4 DEGREE MONTHLY NORMAL. DESPITE
BEING THE 9TH WARMEST JUNE IN DETROIT`S RECORD, THE HEAT STILL FELL
WELL SHORT OF JUNE 1933, THE HOTTEST ON RECORD, WHICH HAD AN AVERAGE
TEMPERATURE OF 74.6 DEGREES.

THE SEVERE WEATHER SEASON REMAINED ON THE QUIET SIDE AS THE HOT AND
DRY ATMOSPHERE, FUELED BY EXPANDING DROUGHT CONDITIONS, LIMITED
THUNDERSTORM ACTIVITY AND RAINFALL IN GENERAL. A COUPLE OF SEVERE
EPISODES DID, HOWEVER, PRODUCE STRONG WINDS RESULTING MOSTLY IN
DOWNED TREES AND POWER LINES ON THE 18TH AND 21ST OF THE MONTH. ONE
PARTICULARLY STRONG THUNDERSTORM RESULTED IN THE CLOSER OF GROSS
ISLE BRIDGE DUE TO WIND DAMAGE. DESPITE THE BRIEF LATE-MONTH SEVERE
WEATHER, DETROIT PICKED UP ONLY 1.31" OF RAINFALL, OR 32% OF THE
3.52" MONTHLY NORMAL. MUCH OF SOUTHEAST MICHIGAN HAD BECOME
ABNORMALLY DRY BY MONTH`S END.

THE AVERAGE HIGH TEMPERATURE FOR THE DETROIT AREA IN JUNE WAS 84.0
+4.7 DEGREES ABOVE THE NORMAL VALUE OF 79.3 AND THE 4TH WARMEST ON
RECORD. THE AVERAGE LOW FOR THE MONTH WAS 60.6, +1.1 DEGREES ABOVE
THE 59.5 DEGREE NORMAL AND TIED FOR THE 31ST WARMEST ON RECORD. THE
AVERAGE OVERALL TEMPERATURE WAS 72.3, A DEPARTURE OF +2.9 ABOVE THE
69.4 DEGREE NORMAL AND THE 9TH WARMEST ON RECORD.
