THE METEOROLOGICAL WINTER OF 2013/2014 WILL BE LONG REMEMBERED...BUT
NOT NECESSARILY FOR THE REASONS MANY FOLKS THINK. TRUE...IT WAS
UNUSUALLY COLD BUT IT WAS NOT THE COLDEST ON RECORD. WHAT DECEMBER 2013
TO FEBRUARY 2014 WILL BE LOGGED AS IT THE CONSISTENCY OF THE COLD.

AT THE GRAND FORKS AIRPORT...WHICH HAS THE SHORTEST PERIOD OF RECORD
IN THE AREA...THE MEAN 3 MONTH TEMPERATURE OF 0.5 DEGREES PUTS IT AS
THE 3RD COLDEST FOR THE AIRPORT LOCATION WHOSE DATA GOES BACK TO 1941.

THE TEMPERATURE DROPPED TO -33 DEGREES ON JANUARY 2ND 2014...THEN HIT
40 DEGREES 10 DAYS LATER ON THE 12TH. THE THREE MONTH MEAN DEPARTURE
FROM NORMAL OF -9.5 DEGREES IS STATISTICALLY IN THE LOWER THIRD OF
COLDEST EXPECTED WINTERS...ANOTHER INDICATOR OF WHAT WE ALREADY KNEW.

TO FURTHER SUPPORT THE IDEA OF CONSISTENT AND FREQUENT COLD HAVE
CALCULATED THE NUMBER OF DAYS WHEN THE LOW TEMPERATURES FELL TO ZERO OR
BELOW. OVER THE PERIOD FROM 1941 TO 2013 THERE ARE 48 DAYS...ON
AVERAGE...THAT THE LOW FALLS TO ZERO OR BELOW DURING THE DECEMBER TO
FEBRUARY PERIOD. THIS WINTER THAT TOTAL WAS 72 DAYS WHICH IS 2ND ONLY
BEHIND THE 1949/1950 WINTER.

THERE WAS 1.89 INCHES OF LIQUID EQUIVALENT WHICH IS ONLY 0.21 INCHES ABOVE
THE LONG TERM AVERAGE.

BECAUSE OF THE COLD WEATHER THE TOTAL 3 MONTH SNOWFALL OF 44.1 INCHES
IS THE 4TH HIGHEST. THE WINTER OF 1996/97 HAD 57.7 INCHES OF SNOW DURING
THE DECEMBER...JANUARY AND FEBRUARY PERIOD.

THE AVERAGE WIND SPEED WAS 12.2 MPH WHICH IS ABOUT 3.5 MPH ABOVE THE LONG
TERM MEDIAN. THE HIGHEST WIND SPEED OF 57 MPH OCCURRED ON JANUARY 16TH.
ANOTHER FACTOR ADDING TO THE OVERALL APPARENT SEVERITY OF THIS WINTER
INCLUDES THE 7 BLIZZARDS THAT IMPACTED THE RED RIVER VALLEY. THIS IS
WELL ABOVE THE USUAL 2 OR 3 THAT OCCUR EVERY WINTER. THE PEAK ON RECORD
OF 10 BLIZZARDS WAS THE 1996/97 WINTER.

THE ABOVE INFORMATION IS PROVISIONAL...IS BASED ON EDITED DATA AND
WILL LIKELY BE CHANGED SLIGHTLY AFTER FURTHER REVIEW BY THE NATIONAL
CLIMATE DATA CENTER. OFFICIAL RECORDS AND SUMMARIES WILL BE
AVAILABLE LATER THIS SPRING OR EARLY SUMMER.
