TEMPERATURE FOR THE YEAR WAS 95 DEGREES ON JUNE 13TH AND THE LOWEST
TEMPERATURE FOR THE YEAR WAS 7 BELOW ZERO ON DECEMBER 27TH.

THERE WERE 10 DAYS WITH A HIGH TEMPERATURE OF AT LEAST 90 DEGREES OR
WARMER.  THIS WAS ABOUT 3 DAYS BELOW NORMAL. THERE WERE 101 DAYS
WITH A LOW TEMPERATURE AT OR BELOW FREEZING. THIS WAS ABOUT 22 DAYS
LESS THAN NORMAL.

NEARLY 3 MORE DAYS THAN NORMAL.

SNOWFALL FOR THE CALENDAR YEAR WAS 18.6 INCHES...14.9 INCHES BELOW

DECEMBER, 2017 WAS THE 3RD LEAST SNOWIEST YEAR ON RECORD WITH JUST
7.2 INCHES.

BELOW IS A MONTH BY MONTH REVIEW OF THE WEATHER IN 2017

JANUARY

...MILD AND WET JANUARY BUT WELL BELOW NORMAL SNOWFALL...

DESPITE ABOVE NORMAL PRECIPITATION THIS MONTH...SNOWFALL AT FORT
WAYNE INTERNATIONAL AIRPORT WAS WELL BELOW NORMAL. THIS WAS DUE TO
THE VERY MILD TEMPERATURES THAT OCCURRED FOR MUCH OF THE MONTH.

JANUARY BEGAN MILD AND WET WITH HIGH TEMPERATURES IN THE 40S ON THE
FIRST THREE DAYS OF THE MONTH. OVER AN INCH OF RAIN COMBINED FELL ON
THE 2ND AND 3RD AS WELL. AN ARCTIC COLD FRONT PUT A QUICK END TO
THESE ABOVE NORMAL TEMPERATURES AND THE 5TH THROUGH THE 8TH
EXPERIENCED AVERAGE TEMPERATURES MORE THAN 10 DEGREES BELOW NORMAL.
THE COLDEST DAY OF THE MONTH OCCURRED DURING THIS STRETCH ON THE 6TH
WITH A HIGH TEMPERATURE OF JUST 12 AND A LOW OF 1 FOR AN AVERAGE
DAILY TEMPERATURE OF 7 DEGREES...18 DEGREES BELOW NORMAL.
TEMPERATURES QUICKLY MODERATED AND A HIGH TEMPERATURE OF 50 DEGREES
WAS REACHED ON THE 10TH. THE REMAINDER OF JANUARY WAS VERY MILD WITH
ONLY ONE DAY BETWEEN THE 10TH AND 31ST EXPERIENCING A BELOW NORMAL
TEMPERATURE.

A RECORD OF 9 CONSECUTIVE DAYS ABOVE FREEZING WAS SET DURING THE
MIDDLE OF THE MONTH FROM JANUARY 17TH THROUGH THE 25TH. THE WARMEST
TEMPERATURE DURING THIS STRETCH WAS 63 ON THE 21ST AND 22ND. THE
COLDEST TEMPERATURE DURING THIS STRETCH WAS 35. THIS BROKE THE OLD
RECORD OF 7 DAYS FROM JANUARY 2ND THROUGH THE 8TH IN 1998.

THE AVERAGE MONTHLY TEMPERATURE WAS 33.1...8.2 DEGREES ABOVE NORMAL.
THIS RANKED AS THE 9TH WARMEST JANUARY ON RECORD. THE HIGHEST
TEMPERATURE FOR THE MONTH WAS 63 ON THE 21ST AND 22ND. THE COLDEST
WAS 0 DEGREES ON THE 7TH. THERE WERE ONLY 10 DAYS WHERE THE HIGH
TEMPERATURE DID NOT GET ABOVE FREEZING.

JANUARY PRECIPITATION WAS 4.71 INCHES...2.45 INCHES ABOVE NORMAL.
THIS RANKED AS THE 10TH WETTEST JANUARY ON RECORD. MEASURABLE
PRECIPITATION FELL ON 16 DAYS AND THREE DAYS HAD A HALF INCH OR MORE
OF PRECIPITATION.

SNOWFALL FOR THE MONTH WAS JUST 1.3 INCHES...8.8 INCHES BELOW NORMAL.
THIS RANKED AS 7TH LEAST SNOWIEST JANUARY. MEASURABLE SNOW FELL ON
JUST 5 DAYS WITH THE GREATEST SINGLE DAY SNOWFALL BEING JUST 0.5
INCHES ON THE 29TH.


FEBRUARY

...RECORD WARM FEBRUARY WITH BELOW NORMAL SNOWFALL...

IT WAS AN INCREDIBLY WARM FEBRUARY IN THE FORT WAYNE AREA WITH
SLIGHTLY BELOW NORMAL PRECIPITATION AND SNOWFALL THAT WAS WELL BELOW
NORMAL. THE DAILY TEMPERATURES DURING FEBRUARY AVERAGED BELOW NORMAL
ON JUST THREE DAYS WHILE 15 DAYS AVERAGED MORE THAN 10 DEGREES ABOVE
NORMAL. THERE WERE EIGHT DAYS THAT AVERAGED 20 DEGREES OR MORE ABOVE
NORMAL.

THE AVERAGE MONTHLY TEMPERATURE WAS 39.8 DEGREES...11.5 DEGREES
ABOVE NORMAL. THIS RANKED AS THE WARMEST FEBRUARY ON RECORD. THE
PREVIOUS RECORD WAS 38.6 DEGREES SET IN 1930. THE WARMEST
TEMPERATURE WAS 71 ON THE 24TH AND THE COLDEST WAS 11 ON THE 9TH.
THE 71 WAS THE 2ND WARMEST FEBRUARY TEMPERATURE EVER RECORDED IN
FORT WAYNE. THE AVERAGE HIGH TEMPERATURE FOR THE MONTH WAS 49.9
DEGREES. THIS WAS A RECORD...SHATTERING THE PREVIOUS RECORD OF 45.8
SET IN 1930. THE AVERAGE LOW TEMPERATURE WAS 29.8. THIS RANKED AS
THE 2ND WARMEST MEAN LOW TEMPERATURE FOR FEBRUARY. THERE WERE ONLY 3
DAYS WITH A HIGH TEMPERATURE THAT DID NOT REACH 32 DEGREES.

THERE WAS 1 DAY THIS MONTH WITH A HIGH TEMPERATURE ABOVE 70...THAT
WAS 71 ON THE 24TH. THIS TIES 1996...1999 AND 2000 AS THE ONLY OTHER
YEARS TO HAVE A FEBRUARY HIGH TEMPERATURE OF 70 DEGREES OR WARMER.
THE WARMEST FEBRUARY TEMPERATURE WAS 73 SET IN 2000. THERE WERE 9
DAYS IN FEBRUARY WITH A HIGH TEMPERATURE OF 60 DEGREES OR WARMER.
THIS BROKE THE RECORD OF 7 SET IN 1976 AND 1930 AS THE MOST NUMBER
OF 60 DEGREE DAYS IN FEBRUARY. HALF OF THE DAYS...14...HAD A HIGH
TEMPERATURE OF 50 DEGREES OR WARMER. THIS WAS A RECORD...SURPASSING
1976 WHICH HAD 13 DAYS ABOVE 50 DEGREES.

FEBRUARY PRECIPITATION WAS SLIGHTLY BELOW NORMAL WITH 1.76 INCHES OF
PRECIPITATION BEING RECORDED. THIS WAS 0.28 INCHES BELOW NORMAL AND
RANKED AS THE 56TH DRIEST FEBRUARY. MORE THAN HALF OF THIS
PRECIPITATION FELL ON JUST TWO DAYS...THE 7TH AND 8TH. MEASUREABLE
PRECIPITATION FELL ON 8 DAYS DURING THE MONTH.

MEASURABLE SNOW FELL ON JUST 3 DAYS FOR A TOTAL OF 2.5 INCHES AND
2.3 INCHES FELL ON THE 8TH. THE MONTHLY TOTAL WAS 5.2 INCHES BELOW
NORMAL AND RANKED AS THE 22ND LEAST SNOWIEST FEBRUARY ON RECORD. THE
RECORD IS A TRACE SET IN 1998.

MARCH

...SEASONABLE TEMPERATURES WITH ABOVE NORMAL RAINFALL IN MARCH...

THE AVERAGE TEMPERATURE FOR MARCH WAS CLOSE TO NORMAL AT FORT WAYNE
INTERNATIONAL AIRPORT WHILE PRECIPITATION WAS ABOVE NORMAL.
TEMPERATURES VARIED SIGNIFICANTLY DURING THE MONTH...BUT AFTER A
VERY WARM FEBRUARY...MARCH FELT COLDER THAN NORMAL TO MANY PEOPLE.
THE MONTH BEGAN WITH SEVERE THUNDERSTORMS AND TEMPERATURES IN THE
60S BUT BY THE 3RD HIGHS WERE ONLY IN THE LOWER 30S AND LOWS WERE IN
THE LOWER 20S ACROSS THE REGION. TEMPERATURES WOULD WARM AGAIN
THOUGH WITH HIGHS BACK IN THE 60S BY THE 5TH. THE REMAINDER OF THE
MONTH WOULD SEE SIMILAR SWINGS FROM WARM TO COLD. THE BIGGEST CHANGE
OCCURRED ON THE 23RD AND 24TH WHEN THE HIGH TEMPERATURE WENT FROM 49
ON THE 23RD TO 76 ON THE 24TH. 2 OF THE FINAL 6 DAYS OF MARCH
CONTAINED STRONG THUNDERSTORMS WITH PRECIPITATION TOTALS REACHING
HIGHER THAN 0.75 INCH OF RAIN EACH DAY.

THE AVERAGE MONTHLY TEMPERATURE WAS 39.4 DEGREES...1.0 DEGREES ABOVE
NORMAL. THIS RANKED AS THE 41ST WARMEST MARCH ON RECORD. THERE WAS
3.81 INCHES OF PRECIPITATION...1.10 INCHES ABOVE NORMAL. THIS RANKED
AS THE 28TH WETTEST MARCH ON RECORD. SNOWFALL FOR MARCH WAS 3.0
INCHES...1.1 INCHES BELOW NORMAL. THIS RANKED AS THE 44TH LEAST
SNOWIEST MARCH ON RECORD.

APRIL

...WARM APRIL WITH NEAR NORMAL PRECIPITATION...

TEMPERATURES AVERAGED WELL ABOVE NORMAL FOR THE MONTH AT FORT WAYNE
WHILE PRECIPITATION WAS SLIGHTLY ABOVE NORMAL. THERE WAS ONE DAY
WITH MEASURABLE SNOW ON APRIL 6TH BUT THE MONTHLY TOTAL WAS BELOW
NORMAL.

IT WAS A RATHER TYPICAL APRIL WITH LARGE VARIATIONS IN TEMPERATURES.
DAILY HIGH TEMPERATURES RANGED FROM THE MIDDLE 40S TO THE MIDDLE 80S
WHILE DAILY LOW TEMPERATURES RANGED FROM THE UPPER 20S TO THE LOWER
60S. THE WARMEST TEMPERATURE FOR THE MONTH WAS 85 ON THE 26TH AND
THE COLDEST TEMPERATURE WAS 29 ON THE 8TH.

THE AVERAGE MONTHLY TEMPERATURE WAS 55.1...5.3 DEGREES ABOVE NORMAL.
THIS RANKED AS THE 5TH WARMEST APRIL ON RECORD. THERE WERE 9 DAYS
WITH AN AVERAGE TEMPERATURE BELOW NORMAL BUT THERE WERE NO DAYS WITH
AN AVERAGE TEMPERATURE MORE THAN 7 DEGREES BELOW NORMAL. IN
CONTRAST...THERE WERE 10 DAYS WITH AN AVERAGE TEMPERATURE OF AT
LEAST 10 DEGREES OR MORE ABOVE NORMAL.

TOTAL PRECIPITATION FOR THE MONTH WAS 3.71 INCHES...0.19 INCHES
ABOVE NORMAL. THIS RANKED AS THE 41ST WETTEST APRIL ON RECORD.
MEASURABLE PRECIPITATION FELL ON 15 DAYS.

THERE WAS 0.4 INCHES OF SNOW...ALL FALLING ON APRIL 6TH. THIS WAS
0.6 INCHES BELOW THE NORMAL OF 1.0 INCHES AND RANKED AS THE 61ST
LEAST SNOWIEST APRIL ON RECORD.

MAY

...A VERY WET MAY WITH NEAR NORMAL TEMPERATURES...

METEOROLOGICAL SPRING CAME TO AN END WITH A VERY WET MAY BUT
TEMPERATURES FOR THE MONTH AVERAGED JUST SLIGHTLY BELOW NORMAL
DESPITE ALL THE RAINFALL. MEASURABLE PRECIPITATION FELL ON JUST OVER
HALF OF THE DAYS IN THE MONTH AND TEMPERATURES WERE BELOW NORMAL ON
16 DAYS. THE AVERAGE DAILY TEMPERATURE WAS BELOW NORMAL ON 11 OF THE
FIRST 13 DAYS. THERE WAS A NICE STRETCH OF WEATHER FROM AROUND THE
14TH THROUGH THE 17TH WITH ABOVE NORMAL TEMPERATURES AND NO
PRECIPITATION. THIS BRIEF WINDOW DID ALLOW MANY FARM FIELDS TO DRY
OUT WHICH GAVE FARMERS A CHANCE TO GET THEIR SPRING CROPS IN.
UNFORTUNATELY THIS WINDOW CAME TO A QUICK CLOSE AS MORE RAIN
RETURNED WITH OVER AN INCH FALLING ON THE 18TH AND NEARLY 3 INCHES
FALLING FROM THE 18TH TO THE 21ST.

THE AVERAGE MONTHLY TEMPERATURE WAS 59.8...0.6 DEGREES BELOW NORMAL.
THIS RANKED AS THE 50TH COOLEST MAY ON RECORD. THE HIGHEST
TEMPERATURE WAS 91 ON THE 18TH. THIS WAS THE 8TH EARLIEST DATE FOR A
90 DEGREE DAY ON RECORD. THE EARLIEST WAS APRIL 11TH 1930. THE
COOLEST TEMPERATURE WAS 31 ON THE 8TH. THIS WAS THE ONLY DAY BELOW
FREEZING IN MAY.

MONTHLY PRECIPITATION WAS 9.22 INCHES...4.95 INCHES ABOVE NORMAL.
THIS RANKED AS THE 2ND WETTEST MAY ON RECORD. MEASURABLE
PRECIPITATION FELL ON 19 DAYS AND AN INCH OR MORE OF RAIN FELL ON 3
DIFFERENT DAYS.

JUNE

...A WARM AND VERY WET JUNE...

JUNE STARTED RELATIVELY DRY WITH ONLY 2 OF THE FIRST 12 DAYS
RECORDING MEASURABLE PRECIPITATION. HOWEVER THE NEXT 12 DAYS, FROM
THE 13TH TO THE 24TH WERE WETTER WITH 10 DAYS RECORDING A TRACE OR
MORE OF PRECIPITATION. THE FIRST 6 DAYS OF THIS SECOND 12 DAY
PERIOD, FROM THE 13TH TO THE 18TH SAW ABOVE NORMAL TEMPERATURES, BUT
THE NEXT 6 DAYS SAW 5 OF THEM CONTAIN BELOW AVERAGE TEMPERATURES.
BELOW AVERAGE TEMPERATURES CONTINUED UNTIL THE 28TH. THE MONTH ENDED
ON A WET NOTE WITH 2 OF THE LAST 8 DAYS RECORDING RECORD PRECIP
TOTALS, THE 23RD AND THE 30TH. IN TERMS OF CROP CONDITIONS, EARLY
MONTH DRYNESS RESULTED IN REDUCED TOPSOIL MOISTURE FOR CROP
DEVELOPMENT, BUT MID MONTH SHOWERS AND STORMS HELPED TO IMPROVE
TOPSOIL MOISTURE AND RECOVER CROP CONDITIONS.

THE AVERAGE MONTHLY TEMPERATURE WAS 71.7...1.6 DEGREES ABOVE NORMAL.
THIS RANKED AS THE 31ST WARMEST JUNE ON RECORD. THE HIGHEST
TEMPERATURES WAS 95 ON THE 13TH. THE COOLEST TEMPERATURE WAS 49 ON
THE 2ND AND THE 8TH.

MONTHLY PRECIPITATION WAS 7.31 INCHES...3.15 INCHES ABOVE NORMAL.
THIS RANKED AS THE 7TH WETTEST JUNE ON RECORD. MEASURABLE
PRECIPITATION FELL ON 12 DAYS AND 0.50 INCH OR MORE FELL ON 4
DIFFERENT DAYS. IN ADDITION, THE 1.79 INCHES OF RAIN THAT FELL ON
THE 23RD WAS A RECORD FOR THAT DAY AND THE 3.01 INCHES THAT FELL ON
THE 30TH WAS A RECORD FOR THAT DAY.

JULY

...NEAR NORMAL TEMPERATURES AND SLIGHTLY ABOVE NORMAL PRECIPITATION
THIS MONTH...

TEMPERATURES AVERAGED CLOSE TO NORMAL IN JULY AND PRECIPITATION WAS
SPREAD RATHER EVENLY THROUGHOUT THE MONTH LEADING TO A SLIGHTLY
BELOW NORMAL JULY. THERE WERE A COUPLE PERIODS OF WARM TEMPERATURES
AND VERY HUMID CONDITIONS, BUT THE HIGH TEMPERATURE ONLY REACHED 90
DEGREES ONCE DURING THE MONTH ON JULY 18TH.

THE AVERAGE MONTHLY TEMPERATURE WAS 73.5 DEGREES, 0.1 DEGREES BELOW
NORMAL. THIS RANKED AS THE 52ND COOLEST JULY ON RECORD.

THERE WAS 4.36 INCHES OF PRECIPITATION, 0.12 ABOVE NORMAL. THIS
RANKED AS THE 31ST WETTEST JULY ON RECORD. MEASURABLE PRECIPITATION
FELL ON 9 DAYS AND 0.50 INCH OR MORE FELL ON 3 DIFFERENT DAYS. 1.89
INCHES OF RAIN FELL ON THE 10TH, BARELY BREAKING THE PREVIOUS RECORD
OF 1.87 INCHES IN 1992.

AUGUST

IT WAS A RELATIVELY COOL AND DRY AUGUST AT FORT WAYNE. THE AVERAGE
MONTHLY TEMPERATURE WAS NEARLY 3 DEGREES BELOW NORMAL AND
PRECIPITATION WAS NEARLY A HALF INCH BELOW NORMAL. MOST OF THE MONTH
HAD ACTUALLY BEEN VERY DRY BUT A NEARLY STATIONARY CLUSTER OF
THUNDERSTORMS OVER THE FORT WAYNE AREA ON THE 29TH OFFICIALLY
DROPPED 2.09 INCHES OF RAIN. HOWEVER, MANY PARTS OF THE CITY AND
ALLEN COUNTY IN GENERAL SAW BETWEEN 3 AND 5 INCHES OF RAIN WHICH
CREATED FLASH FLOODING IN SOME LOCATIONS. THE COMBINATION OF OVERALL
DRY AND RELATIVELY COOL WEATHER DID MAKE FOR A COMFORTABLE MONTH
WITH ONLY A FEW WARM AND MUGGY DAYS.

THERE WERE JUST 9 DAYS DURING AUGUST WITH AN AVERAGE TEMPERATURE
ABOVE NORMAL AND THERE WAS ONLY ONE DAY, THE 21ST, WITH AN AVERAGE
TEMPERATURE MORE THAN 5 DEGREES ABOVE NORMAL. THE REMAINING 22 DAYS
OF AUGUST SAW 3 DAYS WITH NORMAL AVERAGE TEMPERATURES AND 19 DAYS
WITH BELOW NORMAL TEMPERATURES. THE LAST 10 DAYS OF THE MONTH WERE
ALL BELOW NORMAL AND THERE WAS A STRETCH OF DAYS FROM THE 4TH TO THE
14TH WHERE 9 OF THESE 11 DAYS WERE BELOW NORMAL.

DESPITE ALL OF THE BELOW NORMAL TEMPERATURES...AUGUST OF 2017 WAS
JUST THE 12TH COOLEST AUGUST ON RECORD AT FORT WAYNE WITH AN AVERAGE
TEMPERATURE OF 68.7. THIS WAS 2.8 DEGREES BELOW NORMAL. THE COOLEST
AUGUST ON RECORD WAS 1915 WITH AN AVERAGE TEMPERATURE OF 65.7. THE
HIGHEST TEMPERATURE THIS AUGUST WAS 89 ON THE 16TH. ONLY 12 OTHER
AUGUST MONTHS HAVE HAD COOLER MONTHLY MAXIMUM TEMPERATURES AND THERE
HAVE BEEN 22 MONTHS OF AUGUST WHERE THE HIGH TEMPERATURE DID NOT
REACH 90 DEGREES. THE COOLEST TEMPERATURE WAS 46 ON THE 25TH. THIS
RANKED AS THE 26TH COOLEST AUGUST TEMPERATURE ON RECORD. THE RECORD
COOLEST AUGUST TEMPERATURE IS 38 SET IN 1965.

PRECIPITATION FOR THE MONTH WAS 3.16 INCHES, 0.48 INCHES BELOW
NORMAL. THIS RANKED AS THE 61ST DRIEST AUGUST ON RECORD. THE YEAR
1969 HOLDS THE RECORD FOR THE DRIEST AUGUST WITH JUST 0.42 INCHES OF
PRECIPITATION. AUGUST 2017 HAD JUST 6 DAYS WITH MEASURABLE
PRECIPITATION. OVER HALF OF THE MONTHLY RAINFALL FELL ON THE 29TH
WITH 2.06 INCHES BEING RECORDED. THIS WAS ALSO A DAILY RECORD FOR
THE 29TH. WITHOUT THIS RAINFALL ON THE 29TH, THIS AUGUST WOULD HAVE
BEEN THE 4TH DRIEST AUGUST ON RECORD AT FORT WAYNE. THIS RAINFALL
DID HELP KEEP THE YEAR 2017 TO DATE RANKED FIRST FOR WETTEST YEAR ON
RECORD TO DATE. THROUGH AUGUST 31ST, 2017 RANKS AS THE WETTEST YEAR
ON RECORD WITH 38.28 INCHES. THE SECOND WETTEST YEAR ON RECORD TO
DATE IS 1990 WITH 36.90 INCHES.

SEPTEMBER

...WARM AND DRY SEPTEMBER DESPITE COOL START...

SEPTEMBER WAS A WARM AND DRY MONTH WHICH EXPERIENCED FOUR 90 DEGREE
DAYS. THIS MATCHED THE TOTAL NUMBER OF 90 DEGREE DAYS IN JUNE (4)
AND WAS JUST 2 LESS THAN THE COMBINED MONTHS OF MAY, JUNE, JULY AND
AUGUST WHICH HAD A TOTAL OF SIX 90 DEGREE DAYS. ABOUT THREE QUARTERS
OF THE MONTHLY PRECIPITATION FELL ON JUST TWO DAYS AND THERE WERE
ONLY 9 DAYS WITH MEASURABLE PRECIPITATION. THE FIRST HALF OF THE
MONTH ACTUALLY BEGAN RATHER COOL AND WET BUT QUICKLY TRANSITIONED TO
VERY WARM AND DRY DURING THE SECOND HALF.

TWELVE OF THE FIRST FOURTEEN DAYS OF SEPTEMBER SAW BELOW NORMAL
TEMPERATURES. FOUR OF THESE TWELVE DAYS WERE 10 DEGREES OR MORE
BELOW NORMAL. MEASURABLE PRECIPITATION ALSO FELL ON 5 OF THE FIRST 8
DAYS IN SEPTEMBER. THE OVERALL WEATHER PATTERN ACROSS THE UNITED
STATES CHANGED DRASTICALLY MID MONTH AND THIS BROUGHT HEAT, HUMIDITY
AND VERY DRY CONDITIONS TO THE LOCAL AREA DURING THE LATTER HALF OF
THE MONTH. THERE WAS ONLY ONE DAY AFTER THE 13TH WITH AN AVERAGE
TEMPERATURE BELOW NORMAL AND THAT WAS ON THE 30TH.

THE PERIOD FROM SEPTEMBER 20TH TO THE 26TH WAS EXCEPTIONALLY WARM
WITH EACH DAY IN THIS PERIOD AT LEAST 11 DEGREES ABOVE NORMAL AND
THREE DAYS FROM THE 21ST TO THE 23RD HAD HIGH TEMPERATURES OF 90
DEGREES OR WARMER. INCREASED CLOUDS AND HUMIDITY KEPT HIGH
TEMPERATURES ON THE 24TH AND 25TH AT 89 DEGREES BUT THE HIGH ON THE
26TH REACHED 90 AGAIN.

SO JUST HOW WARM WAS THIS PERIOD FROM THE 20TH TO THE 26TH COMPARED
TO PREVIOUS YEARS? THE AVERAGE TEMPERATURE DURING THIS STRETCH WAS
76.2 DEGREES WITH 4 DAYS HAVING A HIGH TEMPERATURE OF 90 OR HIGHER.
THIS WAS THE WARMEST STRETCH ON RECORD BETWEEN THESE DATES,
SURPASSING 1920 WHICH HAD AN AVERAGE TEMPERATURE OF 73.6 DEGREES.

THE AVERAGE MONTHLY TEMPERATURE FOR SEPTEMBER 2017 WAS 65.9, 1.6
DEGREES ABOVE NORMAL. THIS RANKED AS THE 43RD WARMEST SEPTEMBER ON
RECORD. THE HIGHEST TEMPERATURE WAS 92 ON THE 22ND AND THE COOLEST
TEMPERATURE WAS 42 ON THE 30TH.

THERE WAS JUST 1.67 INCHES OF PRECIPITATION RECORDED, 1.13 INCHES
BELOW NORMAL. THIS RANKED AS THE 30TH DRIEST SEPTEMBER ON RECORD.


OCTOBER

...WARM TEMPERATURES AND BELOW NORMAL PRECIPITATION FOR OCTOBER...

OCTOBER BEGAN WARM BUT QUICKLY TURNED COOL DURING THE LAST WEEK OF
THE MONTH. THE FIRST THREE WEEKS WERE VERY WARM WITH HIGH
TEMPERATURES IN THE 60S, 70S AND 80S BUT THE LAST 8 DAYS WERE VERY
COOL WITH HIGH TEMPERATURES ONLY IN THE 40S AND 50S. WHILE PARTS OF
NORTHWEST INDIANA SAW NEAR RECORD RAINFALL IN OCTOBER, THE FORT
WAYNE AREA WAS SLIGHTLY BELOW NORMAL FOR THE MONTH.

THROUGH THE FIRST 23 DAYS OF THE MONTH, TEMPERATURES WERE AT OR
ABOVE NORMAL ON ALL BUT ONE DAY. EACH DAY FROM THE 24TH THROUGH THE
31ST WAS BELOW NORMAL WITH TWO DAYS AT LEAST 10 DEGREES BELOW
NORMAL. THE FIRST WIDESPREAD FROST AND FREEZE OCCURRED DURING THIS
LAST WEEK OF OCTOBER, WHICH WAS LATER THAN NORMAL.

THE AVERAGE MONTHLY TEMPERATURE WAS 56.8 DEGREES, 4.2 DEGREES ABOVE
NORMAL. THIS RANKED AS THE 18TH WARMEST OCTOBER ON RECORD. THE
WARMEST TEMPERATURE WAS 84 ON THE 4TH AND THE COLDEST WAS 29 ON THE
26TH. THERE WERE 4 MORNINGS WITH A LOW TEMPERATURE AT OR BELOW 32
DEGREES.

MONTHLY PRECIPITATION TOTALED 2.24 INCHES, 0.60 INCHES BELOW NORMAL.
THIS RANKED AS THE 55TH DRIEST OCTOBER ON RECORD.

THERE WAS A TRACE OF SNOWFALL RECORDED ON THE 27TH. NORMAL OCTOBER
SNOWFALL IS 0.3 INCHES.


NOVEMBER

...NOVEMBER VERY WET WITH NEAR NORMAL TEMPERATURES...

WHILE THE LAST WEEK OF NOVEMBER EXPERIENCED NEAR NORMAL TO ABOVE
NORMAL TEMPERATURES AND BELOW NORMAL PRECIPITATION...THE SECOND AND
THIRD WEEKS OF THE MONTH WERE COOL AND GENERALLY WET. THIS WAS A
REVERSAL FROM A WARM AND DRY OCTOBER. DESPITE BEING VERY WET, ONLY A
TRACE OF SNOWFALL WAS RECORDED DURING THE ENTIRE MONTH.

THE AVERAGE MONTHLY TEMPERATURE WAS 42.0 DEGREES, 0.6 DEGREES ABOVE
NORMAL. THIS RANKED AS THE 37TH WARMEST NOVEMBER ON RECORD AT FORT
WAYNE. THE WARMEST TEMPERATURE WAS 68 ON THE 5TH. THE COLDEST
TEMPERATURE OF 21 OCCURRED ON THE 11TH.

TOTAL PRECIPITATION FOR THE MONTH WAS 5.49 INCHES WHICH WAS 2.40
INCHES ABOVE NORMAL. THIS RANKED AS THE 4TH WETTEST NOVEMBER ON
RECORD. MORE THAN HALF OF THE TOTAL MONTHLY PRECIPITATION FELL ON
JUST ONE DAY, THE 18TH WITH 2.96 INCHES BEING MEASURED. THIS BROKE
THE DAILY RAINFALL RECORD FOR THE 18TH AND ALSO SET A NEW SINGLE DAY
MONTHLY RAINFALL RECORD FOR NOVEMBER AT FORT WAYNE. THE PREVIOUS
SINGLE DAY NOVEMBER RAINFALL RECORD WAS 2.53 INCHES SET ON NOVEMBER
29TH, 2011. ALL OF THE MONTHLY PRECIPITATION FELL ON JUST 10 DAYS
THIS MONTH.

THERE WAS ONLY A TRACE OF SNOWFALL RECORDED IN NOVEMBER. SINCE A
TRACE IS CONSIDERED NON-MEASURABLE, THIS TIED WITH 22 OTHER YEARS IN
WHICH NO MEASURABLE SNOWFALL OCCURRED IN NOVEMBER.

DECEMBER

...IN WITH THE WARMTH, OUT WITH THE COLD...

AFTER A BRUTALLY COLD AND SNOWY STRETCH OF WEATHER TO END DECEMBER,
IT IS HARD TO REMEMBER THAT THE MONTH BEGAN WITH NEAR RECORD WARMTH
AND TEMPERATURES IN THE 50S AND 60S. THOSE WARM TEMPERATURES LASTED
ABOUT 5 DAYS BEFORE A 9 DAY STRETCH OF BELOW NORMAL TEMPERATURES
FOLLOWED BY ANOTHER PERIOD OF 8 DAYS ABOVE NORMAL. THAT WOULD BE THE
END TO ANY WARMTH THOUGH AS BITTERLY COLD AIR STRAIGHT OUT OF
SIBERIA FLUSHED INTO THE CENTRAL AND EASTERN UNITED STATES FOR THE
LAST 8 DAYS OF DECEMBER. TEMPERATURES WERE MORE THAN 20 DEGREES
BELOW NORMAL DURING THIS PERIOD WITH MEASURABLE SNOWFALL ON 7 OF THE
LAST 9 DAYS.

A FEW DAILY RECORDS WERE SET DURING THE MONTH. A RECORD COLD MAXIMUM
TEMPERATURE OF 9 DEGREES WAS RECORDED ON THE 26TH. THIS BROKE THE
PREVIOUS RECORD OF 12 SET IN 1925.  THIS HIGH OF 9 DEGREES WAS ALSO
THE 10TH COLDEST HIGH TEMPERATURE EVER RECORDED IN DECEMBER. A
RECORD DAILY SNOWFALL RECORD WAS ALSO SET ON THE 25TH. SNOWFALL OF
3.6 INCHES WAS RECORDED WHICH BROKE THE PREVIOUS DAILY RECORD OF 3.5
INCHES SET IN 1934.

THE MONTH ENDED WITH 7 STRAIGHT DAYS HAVING HIGH TEMPERATURES OF 20
DEGREES OR COLDER. THIS TIED AS THE LONGEST SUCH STREAK AT FORT
WAYNE. OTHER YEARS WITH THIS CONSECUTIVE STREAK INCLUDED 1917, 1945
AND 1958.

THE AVERAGE MONTHLY TEMPERATURE WAS 27.1, 2.0 DEGREES BELOW NORMAL.
THIS RANKED AS THE 38TH COLDEST DECEMBER ON RECORD AND IRONICALLY
TIED WITH 2016. THE WARMEST TEMPERATURE WAS 61 ON THE 4TH AND THE
COLDEST WAS 7 BELOW ON THE 27TH. THE PERIOD OF DECEMBER 25TH TO
DECEMBER 31ST HAD AN AVERAGE TEMPERATURE OF 7.2 DEGREES WHICH WAS
THE COLDEST EVER RECORDED DURING THIS 7 DAY STRETCH TO END THE
MONTH.

PRECIPITATION FOR THE MONTH WAS 1.01 INCHES, 1.76 INCHES BELOW
NORMAL. THIS WAS THE 18TH DRIEST DECEMBER ON RECORD, YET MEASURABLE
PRECIPITATION FELL ON 12 DAYS. DESPITE HAVING WELL BELOW NORMAL
PRECIPITATION, SNOWFALL FOR THE MONTH WAS ABOVE NORMAL. A TOTAL OF
11.4 INCHES WAS RECORDED WHICH WAS 2.9 INCHES ABOVE NORMAL. THIS
RANKED AS THE 17TH SNOWIEST DECEMBER ON RECORD. THE DISPARITY
BETWEEN PRECIPITATION AND SNOWFALL WAS DUE TO THE VERY COLD
TEMPERATURES AT THE END OF THE MONTH. THIS CREATED LARGE LIQUID TO
SNOW RATIOS WHICH LED TO VERY EFFICIENT SNOW MAKING PROCESSES.
