...A WARM AND MUGGY SUMMER WITH NEAR NORMAL RAIN AT FORT WAYNE...

THE 2010 SUMMER SEASON WAS VERY WARM AND MUGGY AT FORT WAYNE.
RAINFALL WAS VARIABLE DURING THE SUMMER...WITH ABOVE NORMAL RAIN IN
JUNE...BELOW NORMAL RAINFALL IN JULY...AND NEAR NORMAL RAIN DURING
AUGUST. THIS AVERAGED OUT TO NEAR NORMAL RAINFALL FOR THE ENTIRE
SUMMER...DESPITE THE END OF AUGUST BEING QUITE DRY. THE LACK OF RAIN
IN THE LATTER HALF OF AUGUST CONTRIBUTED TO VERY DRY SOIL CONDITIONS
TO END THE SUMMER SEASON.

TEMPERATURES FOR JUNE WERE WELL ABOVE NORMAL AT FORT WAYNE
INTERNATIONAL AIRPORT AND PRECIPITATION WAS ALSO ABOVE NORMAL. IT
WAS A VERY ACTIVE MONTH FOR SEVERE WEATHER AS SEVERAL ROUNDS OF
THUNDERSTORMS CREATED WIDESPREAD DAMAGE AND SEVERAL TORNADOES ACROSS
THE REGION. SEVERE WEATHER OCCURRED ON SEVERAL DIFFERENT DAYS IN
JUNE BUT THE 5TH...18TH AND 23RD PROVED TO BE THE MOST SIGNIFICANT
DAYS.

WARM TEMPERATURES AND VERY HIGH DEW POINTS CONTRIBUTED TO MUGGY
CONDITIONS AND SCATTERED STRONG THUNDERSTORMS DURING THE MONTH OF
JULY. UNFORTUNATELY MANY OF THESE THUNDERSTORMS MISSED THE IMMEDIATE
FORT WAYNE AREA UNTIL LATE IN THE MONTH.

DEW POINTS...WHICH ARE A MEASURE OF THE AMOUNT OF MOISTURE IN THE
AIR...REACHED WELL INTO THE 70S ON SEVERAL DAYS THIS MONTH WHILE
TEMPERATURES ROSE INTO THE 90S. THIS CREATED VERY MUGGY CONDITIONS
AND HEAT INDICES WELL OVER 100 DEGREES. THE HEAT AND HUMIDITY ALSO
HELPED PROVIDE FUEL FOR THUNDERSTORMS WHICH WERE SCATTERED ACROSS
THE REGION THROUGHOUT THE MONTH. SOME OF THESE THUNDERSTORMS DUMPED
OVER 5 INCHES OF RAIN IN AREAS WHILE OTHER LOCATIONS...LIKE FORT
WAYNE...RECEIVED MUCH LESS RAINFALL.

DESPITE ONLY HAVING 0.08 INCHES OF RAINFALL AT FORT WAYNE DURING THE
LAST HALF OF AUGUST...THE ENTIRE MONTH ENDED UP BEING NEAR NORMAL
FOR PRECIPITATION THANKS TO A COUPLE HEAVY RAIN EVENTS DURING THE
FIRST TWO WEEKS. IT WAS A VERY WARM AND HUMID MONTH WITH SEVERAL
DAYS OF TEMPERATURES AROUND 90 AND UNCOMFORTABLE HUMIDITY.

THE AVERAGE TEMPERATURE FOR THE 2010 SUMMER SEASON AT FORT WAYNE WAS
75.3 DEGREES...3.8 DEGREES ABOVE NORMAL. THIS RANKS AS THE 3RD
WARMEST SUMMER ON RECORD AT FORT WAYNE. THE AVERAGE HIGH TEMPERATURE
WAS 85.4 DEGREES...WHICH RANKS AS THE 10TH WARMEST AVERAGE HIGH
TEMPERATURE FOR THE SUMMER SEASON. THE AVERAGE LOW TEMPERATURE WAS
65.1 DEGREES...WHICH RANKS AS THE SECOND WARMEST AVERAGE LOW
TEMPERATURE FOR THE SUMMER SEASON.

PRECIPITATION FOR THE SUMMER WAS 11.21 INCHES...0.01 INCHES BELOW
NORMAL. RAINFALL IN JUNE WAS 0.88 INCHES ABOVE NORMAL...JULY SAW
RAINFALL TOTALS 0.84 INCHES BELOW NORMAL...AND AUGUST WAS RIGHT AT
NORMAL WITH A SMALL DEFICIT OF 0.05 INCHES.

THIS WILL BE REMEMBERED AS A VERY WARM AND HUMID SUMMER. DEW
POINTS...WHICH MEASURE THE AMOUNT OF MOISTURE IN THE
ATMOSPHERE...REACHED WELL INTO THE 70S THROUGHOUT THE ENTIRE SUMMER.
THERE WERE 68 OUT OF 92 DAYS WHERE THE DEW POINT REACHED AT LEAST 65
DEGREES. THIS IS ABOUT 74 PERCENT OF THE DAYS WHICH FELT HUMID TO
MOST PEOPLE. THERE WERE 47 DAYS IN WHICH THE DEW POINT REACHED AT
LEAST 70 DEGREES...WHICH IS CONSIDERED VERY HUMID AND UNCOMFORTABLE.
THIS EQUATES TO ABOUT 51 PERCENT OF THE SUMMER DAYS. FINALLY...THERE
WERE 15 DAYS IN WHICH THE DEW POINT REACHED OR EXCEEDED 75 DEGREES.
THIS IS CONSIDERED VERY OPPRESSIVE AND DANGEROUS AS HEAT STROKE
BECOMES MORE LIKELY FOR THOSE OUTDOORS. THIS EQUATES TO ABOUT 16
PERCENT OF THE DAYS OF THIS SUMMER IN WHICH THESE DANGEROUS
CONDITIONS EXISTED. THE HIGHEST DEW POINT RECORDED AT FORT WAYNE FOR
THE SUMMER WAS 77 DEGREES ON MULTIPLE DAYS.

THE SUMMER OF 2010 SAW THE TRANSITION FROM AN EL NINO...OR WARMER
THAN NORMAL EQUATORIAL PACIFIC OCEAN TEMPERATURES...TO LA NINA
CONDITIONS...OR COOLER THAN NORMAL EQUATORIAL PACIFIC OCEAN
TEMPERATURES. LA NINA CONDITIONS TEND TO KEEP OUR AREA DRIER THAN
NORMAL IN THE FALL SEASON. THIS MAY BE A CONTRIBUTING FACTOR TO THE
RECENT DRY SPELL IN AUGUST AND IT MAY CONTINUE THROUGH THE UPCOMING
FALL SEASON.
