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.

THE UNIVERSITY OF NORTH DAKOTA/NATIONAL WEATHER SERVICE CLIMATE
SITE...UND/NWS...HAS OVER 120 YEARS OF RECORDS TO DRAW FROM. BASED
ON THE DATA COLLECTED THE 3 MONTH TEMPERATURE OF 1.5 DEGREES PUTS IT
AS THE 7TH COLDEST FOR THE UND/NWS LOCATION WHOSE DATA GOES BACK TO
1890.

THE TEMPERATURE DROPPED TO -26 DEGREES ON JANUARY 2ND AND AGAIN ON
THE 6TH 2014...THEN HIT 42 DEGREES 6 DAYS LATER ON THE 12TH. THE
THREE MONTH MEAN DEPARTURE FROM NORMAL OF -9.4 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 1890 TO 2013 THERE ARE 47 DAYS...ON
AVERAGE...THAT THE LOW FALLS TO ZERO OR BELOW DURING THE DECEMBER TO
FEBRUARY PERIOD. THIS WINTER THAT TOTAL WAS 71 DAYS WHICH IS 3RD
PLACE BEHIND THE 2ND PLACE 1949/50 WINTER AND 1ST PLACE 1916/1917
WINTER.

THERE WAS 1.42 INCHES OF LIQUID EQUIVALENT WHICH IS ONLY 0.53 INCHES
BELOW 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 199/97 HAD 57.3 INCHES OF SNOW
DURING THE DECEMBER...JANUARY AND FEBRUARY PERIOD.

THE AVERAGE WIND SPEED WAS 8.0 MPH WHICH IS ABOUT AVERAGE FOR THE IN
TOWN MEDIAN. THE HIGHEST WIND SPEED OF 50 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.
