WHAT A DIFFERENCE A YEAR MAKES. THE SPRING OF 2012 SAW THE BEGINNINGS
OF SIGNIFICANT DROUGHT CONDITIONS OVER THE REGION. HOWEVER THE MARCH
TO MAY 2013 SPRING HAS BEEN 180 DEGREES DIFFERENT. WHILE IT WAS
ALREADY WETTER THAN A YEAR AGO...THE EXTREMELY HEAVY RAINS AT THE
END OF MAY PUSHED THE FARGO AREA INTO 2ND WETTEST METEOROLOGICAL
SPRING ON RECORD. THE 10.71 INCHES OF RAIN FELL SHORT OF THE 1902
SPRING...WHEN 11.44 INCHES FELL.

IT WAS SO WET IN LARGE PART TO THE NEAR RECORD SPRING SNOWFALL. THE
31.3 INCHES REPORTED IS THE 2ND SNOWIEST MARCH TO MAY PERIOD...
FALLING BEHIND 1997 BY JUST 2.3 INCHES. HOWEVER THE 68.4 INCHES OF
SNOW FOR THE WHOLE WINTER SEASON FALLS INTO 11TH PLACE. THE NEXT
SNOWIEST WINTER SEASON WAS THE 1981/1982 SEASON WHEN 69.5 INCHES
FELL.

TEMPERATURE WISE IT RANKS AS THE 9TH COLDEST METEOROLOGICAL SPRING ON
RECORD. THE 36.2 DEGREE AVERAGE WAS 6.8 DEGREES BELOW THE 30 YEAR
AVERAGE. LAST YEAR THE SAME TIME PERIOD AVERAGED 50.2 DEGREES MAKING
2012 THE WARMEST SPRING ON RECORD.

REMEMBER...THIS DATA IS PROVISIONAL AND SUBJECT TO CHANGE. THE FINAL
AND OFFICIAL RECORDS WILL BE AVAILABLE FROM THE NATIONAL CLIMATIC
DATA CENTER.
