15 Years Ago

It is hard to believe that fifteen years have passed by since the “Flood of the Century” in April 1997.  That flood was preceded by what was arguably the most significant blizzard to strike the state of North Dakota since the infamous blizzard in March 1966.  Although the storm impacted Minnesota, the affects were felt the strongest in both North and South Dakota.

The Red River and tributaries over the southern basin were all rising rapidly in early April 1997 as warm temperatures in late March melted the heavy snow pack.  During the first week of April, overland flooding was spreading quickly and Fargo Moorhead was beginning to be surrounded by water.  Then for three days, April 5-7,  two to three inches of rain, freezing rain and finally heavy snow fell on the region wrecking havoc at the same time so many were desperately trying to sandbag.

The blizzard had wind in excess of 50 mph and destroyed hundreds of electric poles leaving many without power for a week or more; yet, our problems that month had only begun.

A Drier March

The average precipitation in March is 1.30 inches and in recent years Fargo Moorhead has frequently exceeded that average.  That excess moisture, in combination with abundant winter snow, led to the flooding in recent years.  Last month was the first March since 2007 to record below average precipitation and the driest since 2005.  In total, March 2012 recorded 0.78 inches of rain and melted snow.

Because of the record breaking warmth in the area last month, many people forgot that March did start off cool with several small snow events.  In total, 2.6 inches was measured officially last month which is well below the average of 9.1 inches.  Those 2.6 inches of snow ranked as only the 29th lowest snow total on record, so recording so little snow in March is certainly not unusual.  In fact, you may remember that no measurable snow was recorded just two years ago in March 2010.

Although the precipitation was not as big of a story as the record breaking warmth was last month, it was certainly a noticeable departure from recent years.

March 2012

March 2012 finished with an average temperature of 41.6 degrees which is 13.8 degrees above the current 30 year average.  That ranked last month as the warmest March on record surpassing March 1910 by 0.7 degrees.  March 1910 was the warmest on record by nearly 5 degrees before being exceeded this year making both March 1910 and 2012 far warmer than any other March since 1881.

Last month by my count we recorded five record high temperatures all in a row from March 15-19, tied on record high on March 11, broke 7 records for highest minimum and tied a record for highest minimum on another day.  In total that was 14 records or ties set during the month.

Probably the most impressive record was the low of 60 degrees set on March 18 which bested the warmest low temperature on any day on record in March by 12 degrees.  Plus, two other days, March 19 and 23 also recorded a low higher than the old monthly high minimum record of 48 degrees.  It was a month that will not be soon forgotten.
