WINTER 2018-19

THE WINTER BEGAN MILD WITH BELOW NORMAL SNOWFALL. PRECIPITATION WAS
GENERALLY BELOW NORMAL IN DECEMBER, UNTIL THE LAST DAY WHEN OVER AN
INCH OF RAIN SWAYED THE MONTHLY TOTAL TO SLIGHTLY ABOVE NORMAL.
JANUARY BEGAN MILD BUT TRENDED CLOSER TO NORMAL MID MONTH. HOWEVER,
A RECORD COLD BLAST FROM THE ARCTIC AND SIBERIA BROUGHT RECORD COLD
TEMPERATURES TO END THE MONTH. PRECIPITATION WAS BELOW NORMAL IN
JANUARY BUT IT WAS THE ONLY MONTH DURING THE WINTER SEASON WITH
ABOVE NORMAL SNOWFALL. FEBRUARY WOULD END THE METEOROLOGICAL WINTER
SEASON WITH NEAR NORMAL TEMPERATURES AND PRECIPITATION BUT BELOW
NORMAL SNOWFALL.

THE AVERAGE MONTHLY TEMPERATURE FOR THE 2018-19 WINTER SEASON WAS
30.6 DEGREES, 3.2 DEGREES ABOVE NORMAL. THIS RANKED AS THE 19TH
WARMEST WINTER SEASON. THE WARMEST TEMPERATURE WAS 59 ON FEBRUARY
7TH. THE COLDEST TEMPERATURE WAS 13 BELOW ZERO ON JANUARY 30TH.

WINTER PRECIPITATION WAS 7.49 INCHES, 0.42 INCHES ABOVE NORMAL. THIS
RANKED AS THE 40TH WETTEST WINTER SEASON ON RECORD.

WINTER SNOWFALL WAS 19.8 INCHES, 6.5 INCHES BELOW NORMAL. THIS
RANKED AS THE 50TH LEAST SNOWIEST WINTER SEASON.

BELOW IS A MONTH BY MONTH SUMMARY OF THE 2018-19 WINTER.


...A MILD START TO METEOROLOGICAL WINTER...

AFTER A COLD NOVEMBER WITH ABOVE NORMAL SNOWFALL, THE FIRST MONTH OF
THE METEOROLOGICAL WINTER SEASON WAS MILD WITH NEAR NORMAL
PRECIPITATION AND BELOW NORMAL SNOWFALL. DECEMBER PRECIPITATION WAS
ACTUALLY AN INCH BELOW NORMAL ON THE 30TH, BUT MODERATE TO LOCALLY
HEAVY RAINFALL OF OVER AN INCH ON THE LAST DAY OF THE MONTH AND YEAR
BROUGHT THE MONTHLY PRECIPITATION TOTAL BACK UP TO SLIGHTLY ABOVE
NORMAL.

IT WAS A RATHER UNEVENTFUL FIRST MONTH OF WINTER WITH MILD
TEMPERATURES AND LITTLE IN THE WAY OF SNOW. DECEMBER BEGAN MILD AND
WET WITH JUST OVER THREE QUARTERS OF AN INCH OF RAINFALL ON THE
FIRST TWO DAYS AND HIGH TEMPERATURES IN THE 50S, REACHING 59 ON THE
2ND. THE COLDEST PERIOD OF THE MONTH AND THE ONLY DAYS WITH AN
AVERAGE TEMPERATURE BELOW NORMAL OCCURRED FROM THE 4TH THROUGH THE
10TH. THE ONLY MEASURABLE SNOW OF THE MONTH, 0.1 INCHES, FELL DURING
THIS PERIOD ON DECEMBER 5TH. THE REMAINDER OF DECEMBER WAS MILD AND
RELATIVELY DRY UNTIL THE 31ST.

THE AVERAGE MONTHLY TEMPERATURE WAS 35.8, 6.7 DEGREES ABOVE NORMAL.
THIS RANKED AS THE 12TH WARMEST DECEMBER ON RECORD, TIED WITH 1994.
THIS MONTHLY AVERAGE TEMPERATURE WAS JUST OVER A DEGREE COLDER THAN
THE NOVEMBER AVERAGE TEMPERATURE. NORMALLY THE DECEMBER MONTHLY
AVERAGE TEMPERATURE IS ABOUT 12 DEGREES COLDER THAN NOVEMBER. THE
WARMEST TEMPERATURE WAS 59 ON THE 2ND AND 31ST WHILE THE COLDEST WAS
16 ON THE 9TH.

MONTHLY PRECIPITATION WAS 2.94 INCHES, 0.17 INCHES ABOVE NORMAL.
THIS RANKED AS THE 35TH WETTEST MONTH ON RECORD. MOST OF THIS
PRECIPITATION FELL ON THE FIRST TWO DAYS AND LAST DAY OF THE MONTH.
A TOTAL OF 1.26 INCHES FELL ON THE 31ST, WHICH WAS A RECORD FOR THAT
DATE. THERE WERE 12 DAYS WITH MEASURABLE PRECIPITATION.

SNOWFALL FOR THE MONTH WAS WELL BELOW NORMAL WITH JUST 0.1 INCHES
FALLING. THIS WAS 8.4 INCHES BELOW NORMAL AND RANKED AS THE 2ND
LEAST SNOWIEST DECEMBER ON RECORD, BEHIND 1931 WHICH ONLY RECORDED A
TRACE OF SNOWFALL.

...THE END OF JANUARY WAS ABOMINABLE...

JANUARY BEGAN VERY MILD, TRENDED CLOSER TO NORMAL MID MONTH, BUT
THEN ENDED ABOMINABLY COLD WITH TEMPERATURES AND WIND CHILLS NOT
SEEN IN THIS REGION IN A LONG TIME. EVERYONES FAVORITE TERM, THE
POLAR VORTEX, HELPED SEND BITTERLY COLD AIR SOUTH FROM THE ARCTIC
RIGHT INTO THE HEART OF THE GREAT LAKES TO END THE MONTH. THE DAILY
AVERAGE TEMPERATURE AT FORT WAYNE ON THE 30TH WAS 31 DEGREES BELOW
NORMAL WHILE ON THE 31ST IT WAS 26 DEGREES BELOW NORMAL. THESE
DEPARTURES FROM NORMAL ARE ESPECIALLY IMPRESSIVE WHEN YOU FACTOR IN
THAT THIS IS NORMALLY THE COLDEST TIME OF THE YEAR ANYWAY. WIND
CHILLS DURING THESE TWO DAYS REACHED TO BETWEEN 35 BELOW AND 50
BELOW ZERO WHILE ACTUAL AIR TEMPERATURES IN THE REGION FELL TO
BETWEEN 10 BELOW AND 20 BELOW ZERO. THE COLDEST TEMPERATURE MEASURED
AT FORT WAYNE INTERNATIONAL AIRPORT WAS 13 BELOW ZERO WHILE THE
COLDEST WIND CHILL WAS 40 BELOW ZERO.

THROUGH THE FIRST 18 DAYS OF JANUARY, THE AVERAGE MONTHLY
TEMPERATURE WAS 33.0 DEGREES, 8.0 DEGREES ABOVE NORMAL.  THE AVERAGE
TEMPERATURE FROM THE 19TH TO THE 31ST WAS JUST 14.8 DEGREES. THIS
RANKED AS THE 16TH COLDEST AVERAGE TEMPERATURE ON RECORD FOR THIS
PERIOD TO END JANUARY. THE WARMEST TEMPERATURE FOR THE MONTH WAS 55
DEGREES ON THE 7TH AND THE COLDEST WAS 13 DEGREES BELOW ZERO ON THE
30TH. THIS WAS A 68 DEGREE DIFFERENCE BETWEEN THE MONTHLY HIGH AND
LOW TEMPERATURE.

THE AVERAGE MONTHLY TEMPERATURE FOR ALL OF JANUARY 2019 ENDED UP
BEING 25.4 DEGREES, 0.5 DEGREES ABOVE NORMAL. THIS RANKED AS THE
64TH WARMEST JANUARY ON RECORD.

PRECIPITATION FOR JANUARY WAS 2.12 INCHES, 0.14 INCHES BELOW NORMAL.
THIS RANKED AS THE 66TH DRIEST JANUARY ON RECORD. DESPITE THE BELOW
NORMAL PRECIPITATION, SNOWFALL WAS ABOVE NORMAL. TOTAL SNOWFALL WAS
14.3 INCHES, 4.2 INCHES ABOVE NORMAL. THIS RANKED AS THE 19TH
SNOWIEST JANUARY ON RECORD.

SEVERAL DAILY RECORDS WERE SET IN JANUARY. A DAILY MAXIMUM
PRECIPITATION RECORD WAS SET ON THE 23RD WITH 0.87 INCHES OF
PRECIPITATION. A RECORD LOW MINIMUM TEMPERATURE RECORD WAS SET ON
THE 30TH WITH A LOW OF 13 DEGREES BELOW ZERO. A RECORD LOW MAXIMUM
TEMPERATURE RECORD WAS SET ON THE 30TH WITH A HIGH OF JUST 0
DEGREES. THE SAME RECORD WAS TIED ON THE 31ST WITH A HIGH OF 6
DEGREES ABOVE ZERO.

...FEBRUARY BROUGHT ABOVE NORMAL TEMPERATURES AND PRECIPITATION...

DESPITE SEVERAL DAYS OF HIGH WINDS, FREEZING RAIN AND ICE, FEBRUARY
ACTUALLY ENDED UP WITH ABOVE NORMAL TEMPERATURES, NEAR NORMAL
PRECIPITATION BUT BELOW NORMAL SNOWFALL.

THE BRIEF BUT BRUTALLY COLD ARCTIC INTRUSION THAT ENDED JANUARY
CARRIED OVER TO START FEBRUARY BUT ONLY BRIEFLY. THE MONTH BEGAN
WITH A LOW TEMPERATURE OF 6 ABOVE ZERO BUT BY THE 2ND DAY OF THE
MONTH, HIGH TEMPERATURES WERE IN THE 40S AND ACTUALLY REACHED 55
DEGREES ON THE 3RD AND 4TH. BASED ON A SEARCH OF CLIMATOLOGICAL
RECORDS, FORT WAYNE CAME UP ONE DEGREE SHY OF THE GREATEST
TEMPERATURE CHANGE OVER A 3 DAY AND 4 DAY PERIOD, GOING FROM A LOW
OF 9 BELOW ZERO ON JANUARY 31ST TO A HIGH OF 55 ON FEBRUARY 3RD FOR
A 3 DAY TEMPERATURE CHANGE OF 64 DEGREES. THE 4 DAY CHANGE WAS 68
DEGREES, GOING FROM A LOW OF 13 BELOW ZERO ON THE 30TH TO A HIGH OF
55 ON THE 3RD.

THE REMAINDER OF FEBRUARY WOULD SEE A ROLLER COASTER RIDE WITH
TEMPERATURES OSCILLATING BETWEEN ABOVE AND BELOW NORMAL AS SEVERAL
WEAK LOW PRESSURE SYSTEMS WOULD MOVE THROUGH THE REGION EVERY COUPLE
OF DAYS. THE LONGEST STRETCH OF ABOVE NORMAL TEMPERATURES WAS JUST 5
DAYS FROM THE 3RD THROUGH THE 7TH AND AGAIN FROM THE 20TH TO THE
24TH.  THE LONGEST STRETCH OF BELOW NORMAL TEMPERATURES WAS 4 DAYS
FROM THE 16TH THROUGH THE 19TH, AND AGAIN FROM THE 25TH THROUGH THE
28TH.

SEVERAL FAST MOVING CLIPPER SYSTEMS WHICH ORIGINATED IN THE PACIFIC
OCEAN COUPLED WITH A LACK OF DEEP COLD AIR IN THE GREAT LAKES
ALLOWED PRECIPITATION ON SEVERAL OCCASIONS TO FALL AS RAIN DURING
THE MONTH. THE TIMING OF THESE SYSTEMS WERE OFTEN LATE AT NIGHT INTO
THE MORNING DAYLIGHT HOURS WHEN SURFACE TEMPERATURES WERE NEAR OR
BELOW FREEZING. THIS LED TO FREEZING RAIN AT THE SURFACE AND
GENERALLY LIGHT ICE ACCUMULATIONS. THE EXCEPTION WAS ON FEBRUARY
12TH WHEN FREEZING RAIN LED TO WIDESPREAD ICE ACCUMULATIONS BETWEEN
ONE AND TWO TENTHS OF AN INCH AND SOME REPORTS BETWEEN TWO TENTHS
AND THREE TENTHS OF AN INCH.

HIGH WINDS ALSO OCCURRED SEVERAL TIMES DURING THE MONTH. THE DAILY
PEAK WIND SPEED AT FORT WAYNE EXCEEDED 40 MPH ON THE 7TH, 8TH, 12TH,
13TH, 15TH, 24TH AND 25TH. THE WIND EVENT ON THE 24TH WAS A HISTORIC
AND LIKELY UNPRECEDENTED EVENT AS WIND GUSTS EXCEEDED 50 MPH DURING
MUCH OF THE DAY AND 58 MPH ON MANY OCCASIONS. THE PEAK GUST FOR THE
DAY WAS 64 MPH.

OVERALL TEMPERATURES WERE ABOVE NORMAL, SNOWFALL WAS BELOW NORMAL
AND PRECIPITATION WAS NEAR NORMAL. THE AVERAGE MONTHLY TEMPERATURE
WAS 30.6, 2.3 DEGREES ABOVE NORMAL. THIS RANKED AS THE 35TH WARMEST
FEBRUARY ON RECORD. PRECIPITATION WAS 2.43 INCHES, 0.39 INCHES ABOVE
NORMAL. THIS RANKED AS THE 34TH WETTEST FEBRUARY. SNOWFALL WAS JUST
5.4 INCHES, 2.3 INCHES BELOW NORMAL. THIS RANKED AS THE 51ST LEAST
SNOWIEST FEBRUARY.
