June 2009 Recap

                          ...TEMPERATURE VARIABILITY IN ITS FINEST...

JUNE WAS ANOTHER GREAT EXAMPLE HOW THE OFTEN OVER-USED TERM "NORMAL"
CAN BE MISLEADING AT TIMES. STRICTLY LOOKING AT THE FINAL JUNE
TEMPERATURE NUMBERS FOR OUR SELECTED LONG TERM CLIMATE SITES...IT IS
TRUE THAT...ON AVERAGE...IT WAS A SLIGHTLY COOL MONTH...WITH MEAN
TEMPERATURES IN GENERAL RUNNING ABOUT A DEGREE OR TWO BELOW NORMAL.
HOWEVER...WHEN SPECIFICALLY LOOKING AT DAILY NUMBERS AT THE SITES...
20 OR MORE DAYS WERE BELOW NORMAL FOR THE MONTH...WITH JUST A TEN
DAY STRETCH OF WARM TO HOT WEATHER DURING MID AND LATE MONTH
SALVAGING A MONTH THAT WOULD HAVE LIKELY GONE DOWN IN THE RECORD
BOOKS FOR ONE OF THE MORE COLDER JUNES. INTERESTINGLY...DESPITE THE
"COOLNESS" OF THE MONTH...IT WAS DURING THIS WARM PERIOD WHEN ONE OF
OUR WARMEST DAYS IN THE LAST COUPLE YEARS OCCURRED...WITH MANY
INTERIOR LOCATIONS REACHING THE MID 90S ON JUNE 24TH. THE UPPER
LEVEL PATTERN BEHIND THE VARIABILITY SEEN DURING JUNE FEATURED BOOK
END (BEGINNING AND END OF THE MONTH) NORTHWEST FLOW CONFIGURATIONS
(SUPPLYING COOL AIR OUT OF CANADA)...WITH A BRIEF PATTERN
REALIGNMENT ALLOWING DEEP GREAT LAKES RIDGING BRINGING THE
AFOREMENTIONED "HEATWAVE" TOWARDS THE MID AND LATE MONTH PERIOD.

MUCH LIKE THE TEMPERATURES...RAINFALL AMOUNTS WERE DECEIVING YET
AGAIN THIS MONTH...WITH AMOUNTS RUNNING A TOUCH ABOVE/BELOW NORMAL.
ONCE AGAIN...THESE VALUES DO NOT TRULY REPRESENT THE CONDITIONS SEEN
DURING THE MONTH...WITH PROLONGED DRY SPELLS BRIEFLY INTERRUPTED BY
A DAY OR TWO OF SOME MUCH NEEDED RAINFALL. WITH THE RELATIVELY DRY
FLOW OUT OF CANADA PERSISTING MUCH OF THE MONTH...SEVERE WEATHER WAS
KEPT TO A MINIMUM...WITH JUST ISOLATED SEVERE WEATHER REPORTED. ONLY
FOUR WARNING WERE ISSUED BY OUR OFFICE DURING JUNE. THIS IS IN STARK
CONTRAST TO LAST JUNE...ONE OF OUR BUSIEST SEVERE THUNDERSTORM
MONTHS ON RECORD.

HERE IS A LOOK AT HOW SOME LOCATIONS FARED WITH RESPECT TO THEIR
AVERAGE TEMPERATURES DURING JUNE 2009 (MAX...MIN...AND MEAN
VALUES REPRESENT AVERAGE VALUES DURING THE MONTH. NORMAL VALUES USED
TO CALCULATE DEPARTURES ARE FROM THE 30 YEAR PERIOD OF 1971-2000):

HERE ARE SOME OF THE MORE NOTABLE WEATHER EVENTS DURING JUNE 2009:

-JUNE 1ST THROUGH THE 10TH...METEOROLOGICAL SUMMER KICKED OFF MORE
LIKE THE MIDDLE OF SPRING...WITH TEMPERATURES WELL BELOW NORMAL FOR
THE FIRST 10 DAYS OF THE MONTH. ON AVERAGE...DAILY TEMPERATURES WERE
A GOOD 5 TO 10 DEGREES (OR MORE!) BELOW NORMAL THROUGH THIS PERIOD.
THE COOLEST CONDITIONS OCCURRED DURING THE EARLY MORNING HOURS OF
JUNE 2ND THROUGH THE 5TH...WHEN MANY LOCATIONS SAW FROST-PRODUCING
LOWS IN THE 30S. A COUPLE OF THE INTERIOR COLDER LOCATIONS EVEN SAW
TEMPERATURES DIP INTO THE 20S...WITH ATLANTA REPORTING THE COLDEST
TEMPERATURES...DROPPING ALL THE WAY DOWN TO 24 DEGREES EARLY ON JUNE
4TH.

-JUNE 7TH AND 8TH...AFTER A DRY START TO THE MONTH...SLOW NORTHWARD
MOVING REMNANTS OF WHICH WAS ONCE A GULF OF MEXICO TROPICAL
DISTURBANCE BROUGHT SOME MUCH NEEDED RAIN TO THE NORTHWOODS...WITH
TWO DAY TOTALS IN MANY LOCATIONS EXCEEDING AN INCH AND A HALF.

-JUNE 21ST THROUGH THE 25TH...AS IF ON QUE...THE OFFICIAL ARRIVAL OF
SUMMER EARLY ON THE 21ST STARTED A 5 DAY STRETCH OF WARM (TO HOT)
WEATHER ACROSS NORTHERN MICHIGAN. HIGHS IN THE 80S ON THE 21ST AND
22ND WERE REPLACED BY READINGS IN THE 90S FOR MANY LOCATIONS DURING
THE AFTERNOON HOURS OF THE 23RD AND 24TH. ON THE 24TH...MID 90S WERE
COMMON (THE HOTTEST READINGS IN THE LAST SEVERAL YEARS) AWAY FROM
THE IMMEDIATE GREAT LAKES SHORELINES. AS ONE WOULD EXPECT...SEVERAL
RECORD HIGHS WERE RECORDED ON THE 24TH. THE HOTTEST TEMPERATURE
OBSERVED ACROSS NORTHERN MICHIGAN WAS 97 DEGREES AT BOTH FIFE LAKE
AND MIO.

-JUNE 28TH THROUGH THE 30TH...THE MONTH ENDED MUCH LIKE IT
BEGAN...WITH UNSEASONABLE COOL TEMPERATURES. THE CULPRIT THIS TIME
WAS A STRONG AND SLOW MOVING LOW PRESSURE...WHICH BROUGHT A
PROLONGED PERIOD OF CLOUDY AND COOL WEATHER TO THE NORTHWOODS.
SEVERAL LOCATION SAW HIGHS STUCK IN THE MID TO UPPER 50S ON THE
30TH...SETTING NEW RECORD LOW HIGH TEMPERATURES FOR THE DATE. IN
ADDITION TO THE COOL READINGS...AND IN DELIGHT TO LOCAL LAWNS AND
FARMERS...MORE RAIN ACCOMPANIED THE STORM SYSTEM...WITH MULTI-DAY
RAINFALL TOTALS OF A HALF INCH OR MORE FOR MANY LOCATIONS.
