WINTER 2017-18

THE WINTER OF 2017-18 WAS CHARACTERIZED BY ALTERNATING STRETCHES
BETWEEN VERY COLD AND WARM WEATHER. EACH PERIOD LASTED BETWEEN ONE
AND THREE WEEKS BEFORE THE PATTERN QUICKLY CHANGED. DURING THE COLD
PERIODS, NORMAL TO ABOVE NORMAL SNOWFALL AND BELOW NORMAL
TEMPERATURES WERE OBSERVED. DURING THE WARM PERIODS, TEMPERATURES
WERE ABOVE NORMAL WHILE PRECIPITATION WAS GENERALLY NEAR OR BELOW
NORMAL.

THE WINTER BEGAN VERY MILD WITH THE FIRST 5 DAYS OF DECEMBER HAVING
HIGH TEMPERATURES IN THE 50S AND 60S. THIS QUICKLY ENDED WHILE ALSO
BEGINNING THE FIRST PATTERN SHIFT OF THE SEASON TO MUCH BELOW NORMAL
TEMPERATURES. DECEMBER SAW TWO STRETCHES OF ABOVE NORMAL
TEMPERATURES AND TWO PERIODS OF BELOW NORMAL TEMPERATURES. OVERALL
THE MONTH ENDED ABOUT 2 DEGREES BELOW NORMAL FOR ITS AVERAGE
TEMPERATURE, NEARLY TWO INCHES BELOW NORMAL FOR PRECIPITATION BUT
JUST SHY OF 3 INCHES ABOVE NORMAL FOR SNOWFALL.

JANUARY SAW THE ALTERNATING WARM AND COLD PATTERN CONTINUE AS THE
MONTH BEGAN WITH ONE OF THE COLDEST BEGINNINGS TO A NEW YEAR ON
RECORD AS TEMPERATURES DROPPED BELOW ZERO. THE SECOND WEEK WAS MILD
BUT FOLLOWED QUICKLY BY ANOTHER VERY COLD PERIOD LASTING THROUGH
ABOUT THE 18TH. THIS WAS AGAIN FOLLOWED BY VERY MILD AIR WITH ABOVE
NORMAL TEMPERATURES THAT LASTED THROUGH THE END OF THE MONTH. THE
AVERAGE MONTHLY TEMPERATURE WAS NEAR NORMAL WHILE PRECIPITATION WAS
ABOUT AN INCH BELOW NORMAL AND SNOWFALL WAS ABOUT 3 INCHES BELOW
NORMAL.

FEBRUARY WAS NOT ABOUT TO BUCKLE THE TREND OF THE SEASON UNTIL A
THREE DAY STRETCH MID MONTH THAT ALTERED THE SEASONAL TOTALS OF
PRECIPITATION AND BROUGHT THEM FROM WELL BELOW NORMAL TO NEAR
NORMAL. FEBRUARY WAS SPLIT IN HALF WITH THE BEGINNING HALF SEEING
TEMPERATURES BELOW NORMAL WHILE THE SECOND HALF WAS ABOVE NORMAL.
SNOWFALL WAS ABOVE NORMAL DURING THE FIRST PORTION OF THE MONTH
THANKS TO CLOSE TO A HALF FOOT OF SNOW WITH ONE STORM SYSTEM. THE
LATTER HALF OF THE MONTH SAW ABOVE NORMAL PRECIPITATION. OVERALL THE
AVERAGE MONTHLY TEMPERATURE AND TOTAL MONTHLY PRECIPITATION WAS WELL
ABOVE NORMAL WHILE SNOWFALL WAS ALSO ABOVE NORMAL.

THE 2017-18 WINTER SEASON AT FORT WAYNE HAD AN AVERAGE TEMPERATURE
OF 28.5 DEGREES, WHICH WAS 1.1 DEGREES ABOVE NORMAL. THIS RANKED AS
THE 42ND COLDEST WINTER ON RECORD.

PRECIPITATION FOR THE SEASON WAS 6.63 INCHES, 0.44 INCHES BELOW
NORMAL. THIS RANKED AS THE 62ND DRIEST WINTER ON RECORD. OVER 4
INCHES OF THIS PRECIPITATION FELL IN FEBRUARY AND OVER 2 INCHES FELL
IN JUST A 3 DAY PERIOD DURING MID FEBRUARY.

SNOWFALL FOR THE SEASON WAS 28.2 INCHES, 1.9 INCHES ABOVE NORMAL.
THIS RANKED AS THE 29TH SNOWIEST WINTER SEASON ON RECORD.

BELOW IS A MONTH BY MONTH SUMMARY OF THE WINTER SEASON IN THE FORT
WAYNE AREA.

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.

JANUARY

JANUARY WAS A MONTH OF EXTREMES AND FLUCTUATIONS IN THE WEATHER AS
VERY COLD AND WARM TEMPERATURES WERE EXPERIENCED AT TIMES. THE MONTH
BEGAN WITH BITTERLY COLD ARCTIC AIR AND SUB ZERO TEMPERATURES ACROSS
THE REGION MAKING FOR ONE OF THE COLDEST NEW YEAR DAYS IN HISTORY.
THE COLD AIR SUBSIDED BRIEFLY BUT CAME BACK WITH MORE SUB ZERO AIR
DURING THE SECOND AND THIRD WEEKS OF THE MONTH.

THE DIFFERENCE BETWEEN THE WARMEST AND COLDEST TEMPERATURES WAS A
WHOPPING 72 DEGREES AND SEPARATED BY JUST 8 DAYS. THE LOWEST
TEMPERATURE OF THE MONTH WAS 13 DEGREES BELOW ZERO ON THE 2ND AND
THE WARMEST TEMPERATURE WAS 59 DEGREES ON THE 11TH. BOTH OF THESE
TEMPERATURES WERE DAILY RECORDS ON THEIR RESPECTIVE DATES.

DESPITE THE OVERALL FEELING THAT JANUARY WAS COLD, THERE WERE
ACTUALLY MORE DAYS WITH ABOVE NORMAL TEMPERATURES THAN BELOW NORMAL.
HOWEVER, MOST BELOW NORMAL DAYS WERE WELL BELOW NORMAL AND AS MUCH
AS 20 TO 30 DEGREES BELOW NORMAL. THIS WAS DUE TO BITTERLY COLD
ARCTIC AIR THAT INTRUDED DURING TWO SEPARATE PERIODS DURING THE
FIRST HALF OF THE MONTH.  THE PERIOD FROM JANUARY 19TH THROUGH THE
31ST DID NOT HAVE A DAY WITH A BELOW NORMAL AVERAGE TEMPERATURE.
THIS MILD END TO THE MONTH HELPED EVEN OUT THE COLD STRETCHES AND
LED TO A NEAR NORMAL AVERAGE MONTHLY TEMPERATURE.

THE AVERAGE MONTHLY TEMPERATURE WAS 25.2 DEGREES, 0.3 DEGREES ABOVE
NORMAL. THIS RANKED AS THE 65TH WARMEST JANUARY ON RECORD AND TIED
WITH 1927, 1956 AND 2001. THERE WERE 7 DAYS WITH TEMPERATURES BELOW
ZERO. THERE WERE ONLY 11 OTHER JANUARY MONTHS WITH MORE BELOW ZERO
DAYS.

PRECIPITATION FOR THE MONTH WAS 1.25 INCHES WHICH WAS 1.01 INCHES
BELOW NORMAL. THIS RANKED AS THE 27TH DRIEST JANUARY ON RECORD, TIED
WITH THE YEAR 2000.

SNOWFALL WAS ALSO BELOW NORMAL. A TOTAL OF 7.2 INCHES FELL WHICH WAS
2.9 INCHES BELOW NORMAL. THIS RANKED AS THE 55TH LEAST SNOWIEST
JANUARY ON RECORD.

FEBRUARY

...A VERY WET FEBRUARY WITH FLOODING...

WHILE FORT WAYNE WAS JUST MISSED BY HISTORIC RAINFALL WHICH OCCURRED
IN OTHER PARTS OF NORTHERN INDIANA, THE AREA DID SEE VERY WET
CONDITIONS AND MODERATE TO MAJOR FLOODING ON LOCAL RIVERS. OVER 4
INCHES OF PRECIPITATION WAS MEASURED IN FEBRUARY AND OVER HALF OF
THIS PRECIPITATION OCCURRED AS RAIN DURING A 3 DAY STRETCH FROM
JANUARY 19TH THROUGH THE 21ST AND NEARLY 80 PERCENT OF THE MONTHLY
PRECIPITATION FELL BETWEEN THE 19TH AND 25TH.

THE FIRST HALF OF FEBRUARY WAS GENERALLY COLD AND SNOWY WHILE THE
SECOND HALF OF THE MONTH WAS WARM AND WET. ALL BUT 2.3 INCHES OF THE
MONTHLY SNOWFALL OCCURRED BETWEEN THE 1ST AND 10TH WITH A MAXIMUM
SNOW DEPTH OF 5 INCHES ON THE 6TH. WARMER TEMPERATURES HELPED MELT
THIS SNOW BY THE 11TH. RAINFALL THAT OCCURRED DURING THE THIRD WEEK
OF FEBRUARY OVER SATURATED GROUND LED TO FLOODING ON AREA STREAMS,
CREEKS AND RIVERS. SEVERAL RIVERS REACHED MINOR FLOOD STAGE WHILE
FEW REACHED INTO MODERATE AND MAJOR FLOOD ACROSS THE REGION.

TEMPERATURES FOR THE MONTH WERE ABOVE NORMAL WITH AN AVERAGE
TEMPERATURE OF 33.3 DEGREES, 5.0 DEGREES ABOVE NORMAL. THIS RANKED
AS THE 19TH WARMEST FEBRUARY ON RECORD. THE WARMEST TEMPERATURE WAS
70 ON THE 20TH, A RECORD FOR THAT DATE, AND THE COLDEST TEMPERATURE
WAS 1 ABOVE ZERO ON THE 6TH.

MONTHLY PRECIPITATION WAS 4.37 INCHES, 2.33 INCHES ABOVE NORMAL.
THIS RANKED AS THE 8TH WETTEST FEBRUARY ON RECORD.

FEBRUARY SNOWFALL WAS 9.6 INCHES, 1.9 INCHES ABOVE NORMAL. ALL OF
THIS SNOWFALL OCCURRED IN THE FIRST 17 DAYS OF THE MONTH WITH NO
MEASURABLE SNOWFALL AFTER FEBRUARY 17TH. THIS ALSO RANKED AS THE
32ND SNOWIEST FEBRUARY ON RECORD.
