...AN ACTIVE AND VARIABLE WINTER SEASON ACROSS NORTHERN INDIANA...

WHILE SNOWFALL FOR THE METEOROLOGICAL WINTER SEASON FROM DECEMBER
THROUGH FEBRUARY ENDED UP WELL BELOW NORMAL...THERE WERE NUMEROUS
STRONG WEATHER SYSTEMS WHICH BROUGHT MUCH NEEDED PRECIPITATION AND
HIGHLY VARIABLE TEMPERATURES TO THE REGION.

DECEMBER WAS CHARACTERIZED BY AN ACTIVE BUT OVERALL WARM WEATHER
PATTERN...ESPECIALLY DURING THE FIRST HALF OF THE MONTH.
TEMPERATURES WERE MUCH ABOVE NORMAL FOR THE FIRST 20 DAYS OF
DECEMBER WITH DAILY AVERAGE TEMPERATURES 10 TO 20 DEGREES ABOVE
NORMAL. THIS CAUSED MOST PRECIPITATION TO FALL IN THE FORM OF RAIN
INSTEAD OF SNOW. DECEMBER ALSO ENDED A STREAK OF BELOW NORMAL
TEMPERATURES FROM AUGUST TO NOVEMBER. A PATTERN CHANGE FOR THE LAST
PART OF THE MONTH ALLOWED FOR COLDER AIR TO INFILTRATE THE
REGION...BRINGING TEMPERATURES CLOSER TO NORMAL WITH SEVERAL ROUNDS
OF LIGHT SNOWFALL.

TOTAL DECEMBER PRECIPITATION WAS 2.20 INCHES...0.57 INCHES BELOW
NORMAL. SNOWFALL WAS 9.0 INCHES WHICH WAS 0.5 INCHES ABOVE NORMAL.
THE AVERAGE MONTHLY TEMPERATURE OF 36.3 DEGREES WAS 7.2 DEGREES
ABOVE NORMAL. THIS RANKED AS THE 6TH WARMEST DECEMBER ON RECORD.

JANUARY WAS LIKE A WEATHER ROLLER COASTER RIDE AS DRAMATIC UP AND
DOWN SWINGS IN TEMPERATURES WERE RECORDED. HIGH TEMPERATURES TOPPED
OUT IN THE MIDDLE 60S AND LOW TEMPERATURES BOTTOMED OUT AROUND ZERO
DEGREES. JANUARY ALSO SAW ABOVE NORMAL PRECIPITATION WITH A FEW DAYS
OF MODERATE TO HEAVY RAINFALL. THIS HELPED RAISE WATER LEVELS ON
AREA LAKES AND RIVERS AND EVEN LED TO SOME MODERATE FLOODING ON AREA
RIVERS.

SIMILAR TO DECEMBER...SNOWFALL THROUGH JANUARY 20TH WAS WELL BELOW
NORMAL WITH ONLY TWO TENTHS OF AN INCH BEING RECORDED. MOST OF THE
DECEMBER SNOW THEN FELL AFTER THE 20TH WITH JUST OVER 2 INCHES
RECORDED FOLLOWING THE FIRST SIGNIFICANT ARCTIC OUTBREAK OF THE
SEASON. TEMPERATURES CRASHED TO THE SINGLE DIGITS BY THE 21ST. THE
22ND WAS THE COLDEST DAY OF THE WINTER SEASON WITH A HIGH OF ONLY 14
AND A LOW OF 3 DEGREES.

THE AVERAGE MONTHLY TEMPERATURE FOR JANUARY WAS 27.8 DEGREES...2.9
DEGREES ABOVE NORMAL. THE MONTHLY PRECIPITATION WAS 3.43
INCHES...1.17 INCHES ABOVE NORMAL. MONTHLY SNOWFALL WAS 2.6
INCHES...7.5 INCHES BELOW NORMAL. THIS RANKS AS THE 19TH LOWEST
JANUARY SNOWFALL TOTAL SINCE 1912.

AFTER A JANUARY WITH ABOVE NORMAL PRECIPITATION...FEBRUARY SAW
PRECIPITATION DROP BACK BELOW NORMAL ALONG WITH SNOWFALL ENDING UP
SLIGHTLY ABOVE NORMAL. THE FEBRUARY WEATHER PATTERN WAS MORE TYPICAL
OF WINTER ACROSS OUR AREA AS WELL AS MUCH OF THE UNITED STATES WHERE
SEVERAL STRONG BLIZZARDS WITH HEAVY SNOWFALL IMPACTED PARTS OF THE
ATLANTIC SEABOARD AND THE CENTRAL UNITED STATES.

THE AVERAGE MONTHLY TEMPERATURE FOR FEBRUARY WAS 27.5 DEGREES...0.8
DEGREES BELOW NORMAL. PRECIPITATION WAS 1.86 INCHES...0.18 INCHES
BELOW NORMAL. SNOWFALL WAS 8.2 INCHES...0.5 INCHES ABOVE NORMAL.

THE METEOROLOGICAL WINTER SEASON RUNS FROM DECEMBER 1ST THROUGH
FEBRUARY 28TH. DURING THIS PERIOD THE MEAN TEMPERATURE WAS 30.5
DEGREES...3.1 DEGREES ABOVE NORMAL. THIS RANKED AS THE 15TH WARMEST
WINTER SEASON SINCE 1912. THE HIGHEST TEMPERATURE WAS 64 ON JANUARY
30TH AND THE LOWEST TEMPERATURE WAS 2 ON JANUARY 2ND.

THE SEASONAL PRECIPITATION WAS 7.49 INCHES...0.42 INCHES ABOVE
NORMAL. THIS RANKED AS THE 34TH WETTEST WINTER SEASON SINCE 1912.
SNOWFALL WAS 19.8 INCHES...6.5 INCHES BELOW NORMAL. THIS RANKED AS
THE 44TH LEAST SNOWIEST WINTER SEASON SINCE 1912.
