                 ...WEATHER SUMMARY FOR 2009...

         ...THE 2009 WEATHER YEAR IN REVIEW FOR FORT WAYNE...

============================ JANUARY ============================

...A COLD AND SNOWY START TO 2009...

DESPITE A RELATIVELY QUIET AND MILD START TO THE NEW YEAR AT FORT
WAYNE...THE WEATHER CHANGED QUICKLY AND IT BECAME VERY COLD. THE
SECOND WEEK OF THE MONTH SAW A RETURN TO TEMPERATURES BELOW NORMAL
AND A STORM SYSTEM THAT BROUGHT LIGHT SNOW BACK TO THE AREA. IT WAS
ALSO THE BEGINNING OF A PERIOD OF VERY COLD TEMPERATURES AND BRUTAL
WIND CHILLS.

A STRONG UPPER LEVEL SYSTEM MOVED THROUGH THE GREAT LAKES ON THE 9TH
AND 10TH. THIS BROUGHT A PERSISTENT BAND OF LIGHT TO MODERATE SNOW
ACROSS NORTHERN INDIANA AND SOUTHWEST LOWER MICHIGAN...BUT MOST OF
THIS REMAINED JUST NORTH OF FORT WAYNE. WHILE PARTS OF NORTHERN
INDIANA AND NORTHWEST OHIO RECEIVED 6 TO 10 INCHES OF SNOW....FORT
WAYNE ONLY RECORDED 2.2 INCHES DURING THIS STORM. SEVERAL FAST
MOVING CLIPPER SYSTEMS WOULD FOLLOW EVERY FEW DAYS FOR THE REMAINDER
OF THE MONTH. THE FIRST FEW OF THESE CLIPPERS BROUGHT VERY COLD
ARCTIC AIR INTO THE AREA ALONG WITH STRONG WINDS OF 20 TO 30 MPH.
THIS CREATED DEADLY WIND CHILL VALUES BETWEEN 30 BELOW AND 40 BELOW
ZERO BETWEEN THE 14TH AND 17TH...PROMPTING WIND CHILL WARNINGS
ACROSS THE ENTIRE REGION FOR SEVERAL DAYS. TEMPERATURES MODERATED
SLIGHTLY BY THE 22ND AND 23RD BUT ANOTHER ARCTIC INTRUSION OF COLD
AIR OCCURRED BY THE 24TH AND LASTED THROUGH THE END OF THE MONTH.
THE BIGGEST SNOWFALL OF THE SEASON OCCURRED ON THE 27TH AND 28TH AS
LOW PRESSURE MOVED THROUGH THE OHIO VALLEY AND BROUGHT 4 TO 8 INCHES
OF SNOW TO NORTHEAST INDIANA AND NORTHWEST OHIO. FORT WAYNE
OFFICIALLY RECORDED 6.8 INCHES OF SNOW FROM THIS SYSTEM.

THE FIRST STRONG ARCTIC COLD FRONT BROUGHT THE COLDEST TEMPERATURES
IN OVER 30 YEARS BETWEEN JANUARY 13TH AND JANUARY 20TH. DURING THIS
PERIOD...6 OUT OF 8 DAYS HAD LOW TEMPERATURES OF ZERO DEGREES OR
COLDER. THE 15TH AND 16TH WERE THE COLDEST DAYS WITH THE LOW
TEMPERATURE ON THE 15TH BEING NEGATIVE 14...WHICH OCCURRED RIGHT AT
MIDNIGHT...AND THE MORNING LOW ON THE 16TH WAS NEGATIVE 19. THE HIGH
TEMPERATURE ON THE 16TH WAS ONLY 1 ABOVE ZERO. THE FOLLOWING NIGHT
TEMPERATURES ONCE AGAIN PLUMMETED WITH THE LOW IN THE EARLY MORNING
HOURS OF THE 17TH AT 13 DEGREES BELOW ZERO. THESE WERE THE COLDEST
TEMPERATURES AT FORT WAYNE SINCE 1972 WHEN A LOW TEMPERATURE OF
NEGATIVE 19 OCCURRED ON JANUARY 16TH. THIS WAS ALSO THE 4TH COLDEST
TEMPERATURE EVER RECORDED AT FORT WAYNE. THE COLDEST TEMPERATURE
EVER RECORDED WAS NEGATIVE 24...OCCURRING ON JANUARY 12TH 1918.

A TOTAL OF 8 DAYS HAD LOW TEMPERATURES OF ZERO OR COLDER THIS MONTH.
THERE HAVE BEEN 12 OTHER YEARS SINCE 1898 WITH 8 OR MORE DAYS BELOW
ZERO DURING THE MONTH OF JANUARY. JANUARY 1977 HAD THE MOST AT 17. A
TOTAL OF 23 DAYS HAD AVERAGE TEMPERATURES BELOW NORMAL...WITH THE
COLDEST DAY BEING JANUARY 16 WHEN THE AVERAGE TEMPERATURE WAS
NEGATIVE 9...32 DEGREES BELOW NORMAL. ALL OF THIS BITTERLY COLD
ARTIC AIR HELPED JANUARY 2009 TO BECOME THE 7TH COLDEST ON RECORD.
THE AVERAGE MONTHLY TEMPERATURE OF 16.6 DEGREES WAS 7.0 DEGREES
BELOW NORMAL.

PRECIPITATION FOR THE MONTH WAS 1.07 INCHES...0.98 INCHES BELOW
NORMAL. DESPITE THE PRECIPITATION BEING BELOW NORMAL...SNOWFALL WAS
ABOVE NORMAL. FORT WAYNE RECORDED 15.5 INCHES OF SNOW...5.6 INCHES
ABOVE THE NORMAL OF 9.9 INCHES. THIS RANKED AS THE 7TH SNOWIEST
JANUARY ON RECORD AT FORT WAYNE. THIS WAS ALSO THE MOST JANUARY
SNOWFALL SINCE 2005 WHEN 17.2 INCHES FELL. THE SNOWIEST JANUARY ON
RECORD WAS 1982 WHEN 29.5 INCHES FELL.

MEASURABLE SNOW OCCURRED ON 13 DAYS. THE GREATEST SNOW DEPTH FOR THE
MONTH WAS RECORDED ON JANUARY 28TH WHEN 7 INCHES WAS MEASURED ON THE
GROUND. THERE HAS BEEN AT LEAST ONE INCH OR MORE OF SNOW ON THE
GROUND AT FORT WAYNE INTERNATIONAL AIRPORT SINCE JANUARY 10TH...A
STRETCH OF 22 STRAIGHT DAYS.

============================ FEBRUARY ============================

...FEBRUARY WAS MUCH WARMER AND MUCH WETTER THAN NORMAL AT FORT
WAYNE...

FEBRUARY TURNED OUT TO BE THE ONLY MONTH OF THE METEOROLOGICAL
WINTER SEASON...DECEMBER THROUGH FEBRUARY...WITH ABOVE NORMAL
TEMPERATURES AT FORT WAYNE. FEBRUARY WAS ALSO MUCH WETTER THAN
NORMAL BUT SNOWFALL WAS BELOW NORMAL FOR THE MONTH. THERE WERE
SEVERAL DAYS WITH MINOR SNOW ACCUMULATIONS BUT NO SIGNIFICANT SNOW
EVENTS OCCURRED. THERE WERE TWO RATHER SIGNIFICANT RAINFALL EVENTS
WITH ONE SETTING A RECORD WITH OVER 2 INCHES OF RAIN.

THE AVERAGE MONTHLY TEMPERATURE WAS 30.3 DEGREES...3.0 DEGREES ABOVE
NORMAL. 16 OF THE 28 DAYS EXPERIENCED AN AVERAGE TEMPERATURE AT OR
ABOVE NORMAL...WITH 3 DAYS HAVING AN AVERAGE TEMPERATURE OF 20 OR
MORE DEGREES ABOVE NORMAL. THE WARMEST DAY OF THE MONTH OCCURRED ON
THE 10TH WHEN THE HIGH TEMPERATURE HIT 61 DEGREES. THE AVERAGE
TEMPERATURE FOR THIS DAY WAS 53 DEGREES...27 DEGREES ABOVE NORMAL.
IN CONTRAST...12 DAYS HAD AN AVERAGE TEMPERATURE BELOW NORMAL...WITH
THE COLDEST DAYS BEING THE 4TH AND 5TH WHEN THE AVERAGE TEMPERATURE
WAS 9 DEGREES...16 DEGREES BELOW ZERO. THE 4TH AND 5TH ALSO HAD THE
COLDEST LOW TEMPERATURE FOR THE MONTH WITH NEGATIVE 1 RECORDED ON
BOTH DAYS.

PRECIPITATION FOR THE MONTH WAS 3.70 INCHES...1.76 INCHES ABOVE
NORMAL. THE HIGHEST SINGLE DAY PRECIPITATION WAS ON THE 11TH WHEN
2.38 INCHES FELL. THIS WAS A RECORD FOR THIS DATE. A STORM SYSTEM ON
THE 26TH AND 27TH PRODUCED 0.58 INCHES OF PRECIPITATION FOR THE TWO
DAYS COMBINED. THESE TWO RAIN EVENTS MADE UP OVER THREE FOURTHS OF
THE PRECIPITATION FOR THE MONTH. MEASURABLE PRECIPITATION OCCURRED
ON 8 DAYS IN THE MONTH...WHICH IS SLIGHTLY BELOW NORMAL.

SNOWFALL FOR THE MONTH WAS 4.1 INCHES...3.5 INCHES BELOW THE NORMAL
OF 7.6 INCHES. THE HIGHEST SINGLE DAY SNOWFALL OCCURRED ON THE 21ST
WITH 1.6 INCHES.

============================ MARCH =========================

MARCH BEGAN DRY AND COLD AT FORT WAYNE BUT THE WEATHER PATTERN
QUICKLY CHANGED TO WARM AND WET BY THE SECOND WEEK. AS A MATTER OF
FACT...RECORD RAINFALL AND FLOODING OCCURRED ONCE AGAIN ACROSS
NORTHEAST INDIANA AS TWO SIGNIFICANT SYSTEMS BROUGHT HEAVY RAINFALL
TO THE REGION. DURING THE 4 DAY PERIOD FROM MARCH 7TH THROUGH
10TH...4.42 INCHES OF RAIN WAS RECORD AT FORT WAYNE INTERNATIONAL
AIRPORT. MANY RURAL AREAS RECEIVED BETWEEN 4 AND 8 INCHES OF
RAINFALL DURING THIS PERIOD. MOST RIVERS WENT ABOVE FLOOD STAGE
FOLLOWING THIS HEAVY RAIN AND SEVERAL RIVERS HAD MAJOR OR RECORD
FLOODING. TEMPERATURES HAD BEEN IN THE 60S AND 70S LEADING UP TO
THIS HEAVY RAINFALL AND QUICKLY DROPPED BACK INTO THE 20S AND 30S IN
ITS WAKE.

THE FIRST TORNADOES OF THE YEAR FOR THE NWS NORTHERN INDIANA COUNTY
WARNING AREA OCCURRED ON MARCH 8TH AS A POWERFUL STORM SYSTEM MOVED
THROUGH THE GREAT LAKES. AN EF0 TORNADO OCCURRED NEAR COLUMBIA CITY
INDIANA WHILE ANOTHER EF0 TORNADO OCCURRED WEST OF DEFIANCE OHIO.

THE MIDDLE PORTION OF MARCH WAS DRY AND RATHER WARM WITH GENERALLY
ABOVE NORMAL TEMPERATURES. THIS DRY STRETCH ALLOWED MANY AREA LAKES
AND RIVERS TO SLOWLY RECEDE AFTER THE RECORD FLOODING EARLIER IN THE
MONTH. WET WEATHER RETURNED DURING THE LAST WEEK OF MARCH AS SEVERAL
STORM SYSTEMS MOVED THROUGH THE GREAT LAKES AND OHIO VALLEY REGION.
FORTUNATELY THIS RAIN DID NOT CAUSE ANY RENEWED FLOODING BUT DID
SATURATE THE SOILS AGAIN.

THE AVERAGE MONTHLY TEMPERATURE OF 42.2 DEGREES WAS 4.1 DEGREES
ABOVE NORMAL. THE HIGHEST TEMPERATURE WAS 71 ON THE 7TH AND 17TH AND
THE COLDEST TEMPERATURE WAS 8 ABOVE ZERO ON THE THIRD. PRECIPITATION
FOR THE MONTH WAS 5.70 INCHES...2.84 INCHES ABOVE NORMAL. THIS RANKS
AS THE 6TH WETTEST MARCH ON RECORD AT FORT WAYNE. MEASURABLE
PRECIPITATION OCCURRED ON JUST 9 DAYS DURING THE MONTH...BUT ON
THREE OF THESE DAYS THE PRECIPITATION RECORDED WAS OVER ONE
INCH...WITH 1.96 INCHES RECORDED ON THE 8TH. SNOWFALL WAS JUST A
TRACE FOR THE MONTH...WHICH TIES AS THE SECOND LEAST SNOWIEST
MARCH ON RECORD. THERE WERE ONLY THREE DAYS DURING THE MONTH IN
WHICH A TRACE OF SNOWFALL WAS RECORDED.

FORT WAYNE BROKE TWO PRECIPITATION RECORDS ON MARCH 8TH AND 10TH
WITH RESPECTIVE AMOUNTS OF 1.96 AND 1.53 INCHES OF RAINFALL. FORT
WAYNE ALSO TIED A HIGH TEMPERATURE RECORD ON THE 17TH WITH 71
DEGREES.

============================ APRIL ============================

...NEAR NORMAL TEMPERATURES BUT ABOVE NORMAL PRECIPITATION FOR
APRIL...

DESPITE OVER AN INCH OF SNOW AND ABOVE NORMAL PRECIPITATION...APRIL
ACTUALLY ENDED UP BEING NEAR NORMAL FOR TEMPERATURES AT FORT WAYNE.
TEMPERATURES VARIED DRASTICALLY DURING THE MONTH...WITH HIGHS
RANGING FROM THE LOWER 40S TO MIDDLE 80S. OVER HALF THE DAYS IN THE
MONTH HAD SOME FORM OF PRECIPITATION...WITH TWO DAYS SEEING AT LEAST
A TRACE OF SNOW AND ONE DAY HAVING MEASURABLE SNOWFALL.

THE MONTH BEGAN MILD AT FORT WAYNE WITH HIGH TEMPERATURES IN THE 50S
ON THE FIRST AND NEAR 70 ON THE SECOND. HOWEVER...A STRONG STORM
SYSTEM THAT ALLOWED THE WARMER TEMPERATURES TO SPREAD INTO THE
REGION MOVED INTO THE GREAT LAKES AND BROUGHT WET AND COLD
CONDITIONS TO NORTHERN INDIANA. THIS SYSTEM WAS COLD ENOUGH TO TURN
THE RAIN INTO SNOW AS IT BEGAN TO MOVE EAST. FORT WAYNE RECORDED AN
INCH AND A HALF OF SNOWFALL ON THE 6TH. SOME LOCATIONS JUST NORTH
AND WEST OF FORT WAYNE RECEIVED BETWEEN 3 AND 6 INCHES OF SNOW.
WINTER WEATHER ADVISORIES WERE ISSUED FOR THIS SPRING SNOW STORM.

TEMPERATURES CONTINUED TO SWING DRASTICALLY OVER THE REMAINDER OF
THE MONTH WITH HIGH TEMPERATURES RANGING FROM THE LOWER 40S ON THE
13TH AND 14TH...TO THE LOWER AND MIDDLE 80S ON THE 24TH THROUGH THE

MONTH. SNOWFALL FOR THE MONTH WAS 1.5 INCHES...JUST 0.4 INCHES ABOVE
THE NORMAL OF 1.1 INCHES.

============================ MAY ============================

...NEAR NORMAL TEMPERATURES AND BELOW NORMAL PRECIPITATION...

THE MONTH OF MAY AT FORT WAYNE WAS NEAR NORMAL WITH RESPECT TO
TEMPERATURES BUT PRECIPITATION WAS WELL BELOW NORMAL. THE RELATIVELY
QUIET SEVERE WEATHER SEASON CONTINUED THROUGH MAY WITH ONLY A FEW
WARNINGS BEING ISSUED ACROSS THE AREA.

THE AVERAGE MONTHLY TEMPERATURE WAS 60.2 DEGREES....2 DEGREES BELOW
NORMAL. THE HIGHEST TEMPERATURE WAS 85 ON THE 23RD AND 27TH. THE

============================ JUNE ============================

...NEAR NORMAL TEMPERATURES AND PRECIPITATION...

TEMPERATURES FOR THE MONTH OF JUNE WERE SLIGHTLY ABOVE NORMAL AT
FORT WAYNE INTERNATIONAL AIRPORT WHILE PRECIPITATION FOR THE MONTH

WHILE THE OVERALL AVERAGE MONTHLY TEMPERATURE OF 70.5 DEGREES WAS
ONLY 0.8 DEGREES ABOVE NORMAL...ACTUAL DAILY TEMPERATURES VARIED
SIGNIFICANTLY DURING THE MONTH. HIGH TEMPERATURES RANGED FROM THE
LOWER 60S TO THE MIDDLE 90S...AND LOW TEMPERATURES RANGED FROM THE
LOWER 40S TO LOWER 70S. THE WARMEST DAY OF THE MONTH WAS ON THE 25TH
WITH A HIGH OF 95. IN CONTRAST...THE HIGH TEMPERATURE ON JUNE 3RD

IT WAS ANOTHER RELATIVELY QUIET MONTH WITH RESPECT TO SEVERE
WEATHER. JUNE 19TH WAS THE MOST ACTIVE DAY WITH NUMEROUS SEVERE
THUNDERSTORM WARNINGS AND A FEW TORNADO WARNINGS BEING ISSUES ACROSS
NORTHERN INDIANA AND NORTHWEST OHIO. SEVERE THUNDERSTORMS ON THE
19TH PRODUCED WIND DAMAGE WITH NUMEROUS TREES AND POWERLINES
REPORTED DOWN FROM 60 TO 70 MPH WINDS. LARGE HAIL UP TO GRAPEFRUIT

============================ JULY ============================

...RECORD COLDEST JULY AT FORT WAYNE...

THIS JULY RANKS AS THE COLDEST JULY ON RECORD IN THE FORT WAYNE
AREA. OFFICIAL RECORDS FOR THE FORT WAYNE AREA BEGAN IN 1897. THE
AVERAGE MONTHLY TEMPERATURE FOR JULY 2009 WAS 68.9 DEGREES...4.5
DEGREES BELOW NORMAL. THE PREVIOUS RECORD WAS 69.7 DEGREES SET IN
1967. A PERSISTENT TROUGH OF LOW PRESSURE ACROSS EASTERN CANADA AND
THE EASTERN UNITED STATES HAS HELPED TO FUNNEL COOL CANADIAN AIR
INTO THE GREAT LAKES AND OHIO VALLEY FOR MOST OF THE SUMMER WHILE
KEEPING THE HOT AND HUMID WEATHER WELL TO OUR WEST. IN ADDITION TO
THE COOLER THAN NORMAL AIR...BELOW NORMAL DEW POINTS HAVE HELPED
MAKE THE SUMMER FEEL MORE LIKE FALL WITH VERY LOW BUT COMFORTABLE
RELATIVE HUMIDITIES.

IT HAS BEEN SO COOL THAT ON TWO SEPARATE OCCASIONS RARE JULY LAKE
EFFECT RAIN SHOWERS OCCURRED ACROSS SOUTHWEST LOWER MICHIGAN AND
NORTHWEST INDIANA. THIS OCCURRED AT THE BEGINNING OF JULY ON THE 1ST
AND 2ND AND AGAIN IN MID JULY AROUND THE 18TH. ON BOTH
OCCASIONS...HIGH TEMPERATURES REMAINED IN THE 60S AND LOWER 70S
ACROSS THE AREA WHILE TEMPERATURES IN THE LOWER PART OF THE
ATMOSPHERE WERE COLD ENOUGH TO HELP GENERATE LAKE EFFECT RAIN
SHOWERS OVER THE RELATIVELY WARMER WATERS OF LAKE MICHIGAN. SOME OF
THESE LAKE EFFECT SHOWERS EVENTUALLY MADE THEIR WAY INTO NORTHEAST
INDIANA.

THE AVERAGE MONTHLY TEMPERATURE WAS 68.9 DEGREES...4.5 DEGREES BELOW
NORMAL. THE HIGHEST TEMPERATURE WAS 87 DEGREES ON THE 10TH AND THE
COOLEST TEMPERATURE WAS 49 ON THE 14TH. THE LAST TIME THE HIGHEST
TEMPERATURE IN JULY WAS JUST 87 DEGREES WAS IN JULY 2000...ALL OTHER
JULY HIGHEST TEMPERATURES ON RECORD HAD A HIGH TEMPERATURES OF AT
LEAST 88 DEGREES. THE AVERAGE HIGH TEMPERATURE WAS 79.2 DEGREES...
WHICH IS THE RECORD COOLEST AVERAGE HIGH TEMPERATURE FOR JULY. JULY
1915 PREVIOUSLY RANKED COLDEST AT 79.9 DEGREES. THE AVERAGE MONTHLY
LOW TEMPERATURE WAS 58.5 DEGREES AND THIS RANKED AS THE 3RD COOLEST
FOR AVERAGE LOW TEMPERATURES.

ONLY 3 OF THE 31 DAYS OF JULY 2009 HAD AN AVERAGE TEMPERATURE ABOVE
NORMAL. JULY 28TH WAS THE WARMEST DAY OF THE MONTH WITH AN AVERAGE
TEMPERATURE OF 75 DEGREES...JUST 2 DEGREES ABOVE NORMAL. THERE WAS 1
DAY WITH THE AVERAGE TEMPERATURE AT LEAST 10 DEGREES BELOW NORMAL
AND THAT WAS THE COLDEST DAY OF THE MONTH ON JULY 4TH. THE HIGH WAS
ONLY 72 AND THE LOW WAS 52 FOR AN AVERAGE TEMPERATURE OF 62...11
DEGREES BELOW NORMAL. FORT WAYNE ALSO BROKE RECORDS FOR COOLEST HIGH
TEMPERATURES ON 2 SEPARATE DAYS. JULY 17TH AND 22ND BOTH HAD RECORD
COOL HIGH TEMPERATURES.

COLD CANADIAN AIR COUPLED WITH ABOVE NORMAL CLOUD COVER WERE THE
MAIN REASONS FOR KEEPING TEMPERATURES WELL BELOW NORMAL.
PRECIPITATION FOR THE MONTH ACTUALLY ENDED UP BEING ABOVE NORMAL
AFTER BEING BELOW NORMAL FOR MUCH OF THE MONTH. FORT WAYNE RECORDED
4.22 INCHES OF RAINFALL...0.64 INCHES ABOVE NORMAL.

THE SUMMER MONTHS OF JUNE AND JULY HAVE BEEN WELL BELOW NORMAL FOR
AVERAGE TEMPERATURES. 14 OUT OF 30 DAYS IN JUNE HAD AN AVERAGE
TEMPERATURE AT OR BELOW NORMAL WHILE JULY SAW AN IMPRESSIVE 28 OUT
OF 31 DAYS WITH AVERAGE TEMPERATURES AT OR BELOW NORMAL.

============================ AUGUST ============================

...COOL AND SLIGHTLY WET AUGUST AT FORT WAYNE...

WHILE AUGUST WAS NOT NEAR AS COOL AS JULY...IT STILL ENDED WITH
BELOW NORMAL TEMPERATURES AND PRECIPITATION THAT WAS ABOVE NORMAL.

THE AVERAGE MONTHLY TEMPERATURE WAS 69.7 DEGREES...1.4 DEGREES BELOW
NORMAL. THE AVERAGE HIGH TEMPERATURE WAS 79.6 WHILE THE AVERAGE LOW
TEMPERATURE WAS 59.8. THERE WAS A STRETCH OF 10 STRAIGHT DAYS WITH
HIGH TEMPERATURES AT OR ABOVE 80 DEGREES...WHICH WAS THE SECOND
LONGEST STREAK OF THE SUMMER. HOWEVER...19 OUT OF 31 DAYS
EXPERIENCED AVERAGE TEMPERATURES AT OR BELOW NORMAL AND THERE WERE
NO DAYS WITH AVERAGE TEMPERATURES MORE THAN 9 DEGREES ABOVE NORMAL.

THE HIGHEST TEMPERATURE OF THE MONTH WAS 92 ON THE 16TH. THE COOLEST
TEMPERATURE OF THE MONTH WAS ON THE MORNING OF THE 31ST WHEN THE LOW
TEMPERATURE WAS A CHILLY 45 DEGREES...JUST 2 DEGREES WARMER THAN THE
RECORD LOW FOR THAT DATE.

AUGUST PRECIPITATION WAS ABOVE NORMAL WITH 4.24 INCHES
FALLING...WHICH IS 0.64 INCHES ABOVE NORMAL. A LARGE PORTION OF THIS
MONTHLY RAINFALL TOTAL OCCURRED DURING THE MIDDLE OF THE MONTH AND
ON JUST A SINGLE DAY. BETWEEN AUGUST 16TH AND 22ND...NEARLY 90 PERCENT
OF THE MONTHS TOTAL RAINFALL OCCURRED. 3.80 INCHES OF RAIN FELL
DURING THIS PERIOD...WITH A SINGLE DAILY RECORD RAINFALL OF 3.24
INCHES FALLING ON AUGUST 17TH. MANY AREAS WEST OF FORT WAYNE RECORDED
EVEN MORE RAINFALL ON THE 17TH...WITH SOME PARTS OF SOUTHERN ELKHART
AND NORTHERN KOSCIUSKO COUNTIES RECEIVING OVER 8 INCHES OF RAIN.
PARTS OF ALLEN COUNTY ALSO REPORTED BETWEEN 4 AND 5 INCHES OF RAIN.

============================ SEPTEMBER ============================

...A SEASONABLY WARM AND DRY SEPTEMBER...

VERY STRONG WINDS AND SEASONABLY COOL TEMPERATURES. THE HIGHEST
TEMPERATURE OF THE MONTH WAS 83 ON THE 15TH AND THE COLDEST
TEMPERATURE WAS 40 ON THE 30TH.

IT WAS A RATHER DRY MONTH AT FORT WAYNE AS THE MONTHLY RAINFALL
TOTAL WAS ONLY 1.41 INCHES...1.40 INCHES BELOW NORMAL. RAINFALL WAS
GENERALLY SCATTERED THROUGH THE MONTH WHICH RESULTED IN SOME AREAS
SEEING SIGNIFICANTLY MORE RAIN THAN OTHERS. THE GREATEST SINGLE DAY
RAINFALL TOTAL AT FORT WAYNE THIS MONTH WAS ONLY 0.54 INCHES ON THE
8TH.

============================ OCTOBER ============================

...A VERY COOL AND WET OCTOBER...

THE FIRST HALF OF OCTOBER FELT MORE LIKE NOVEMBER AS TEMPERATURES
AVERAGED WELL BELOW NORMAL DURING THE FIRST 19 DAYS OF THE MONTH. IT
WAS ALSO A RATHER WET MONTH AS PRECIPITATION WAS ABOVE NORMAL AND
OCCURRED ON OVER HALF OF THE DAYS OF THE MONTH.

THE FIRST 19 DAYS OF OCTOBER AT FORT WAYNE INTERNATIONAL AIRPORT HAD
AVERAGE TEMPERATURES BELOW NORMAL. FIVE OF THE 19 DAYS AVERAGED 10
OR MORE DEGREES BELOW NORMAL...WITH A STRETCH OF CONSECUTIVE DAYS
FROM OCTOBER 10TH THROUGH THE 18TH ALL HAVING AVERAGE TEMPERATURES
AT LEAST 7 DEGREES BELOW NORMAL. THE COLDEST DAY OF THE MONTH WAS
OCTOBER 11TH WITH A HIGH OF 48 AND A LOW OF 35 FOR AN AVERAGE
TEMPERATURE OF 42...12 DEGREES BELOW NORMAL. THE WARMEST TEMPERATURE
OF THE FIRST 19 DAYS OF THE MONTH WAS 66 DEGREES...OCCURRING ON THE
5TH. IT WAS NOT UNTIL OCTOBER 20TH THAT THE MONTH HAD ITS FIRST DAY
