April 2015 Stats

A summary of some April stats for the area:

 

Average temperatures across the North Dakota Agricultural Weather Network(NDAWN) are presented below.  The last several days of April certainly helped take an average or slightly below average month it push it more into a slightly above average temperature April.

Departures from the April 30 year average temperature ranged mostly from -2 to +2 across the NDAWN Weather Stations, making April 2015 a very average month for the state of North Dakota into northwestern ND.

Although April finished near the average for temperature, most of the NDAWN network finished well below average for precipitation:   Total precipitation over the NDAWN mesonet averaged between 0.33 and 0.66 inches, which is well below the 1.00 to 1.40 inch average for much of the state.  The statewide average is currently 1.22 inches and only one NDAWN station recorded rainfall above that level.

Taken as a percent of average precipitation, that amount of moisture would equate to 30% to 60% of normal.

Because the NDAWN stations only record precipitation during the principal rainy months (April through October), the percent of normal precipitation for the past 6 months is presented below based on analysis from the High Plains Regional Climate Center (HPRCC) below, that takes data from airports and cooperative observers in the region.  This gives a perspective on the lack of snow and rainfall over the past 6 months.

The Fargo Airport recorded an average temperature of 47.1°, 3.0 degrees above average which would rank last month as the 21st warmest April of record.  The airport sensor recorded 0.98 inches of rain (and melted snow).  That is 0.38 inches below the current 30 year average of 1.36 inches of rain for that location.  That would rank as the 34th driest April of record.  This compares to the 3.43 inches that fell during April 2014 that ranked as the 18th wettest on record.

The University of North Dakota (UND) sensor, now located at the National Weather Service (NWS) offices in Grand Forks had an average temperature of 44.4° in April 2015 which would rank as the 32nd warmest April on record for that location.   The NWS recorded 0.73 inches of rain and melted snow for the month which would rank as the 35th driest April on record.  That 0.73 inches is 0.25 inches below the 30 year average of 0.98 inches for the month of April.

The average temperature at the Bismarck Airport in April 2015 was 45.4 degrees which is 1.6 degrees above average.  That would rank last month as tied for the 42nd warmest April on record for that location.  The Bismarck Airport recorded 0.37 inches of rain/melted snow during the month of April 2015.  That would rank as tied for the 15th driest April of record.   That 0.37 inches of moisture is 0.89 inches below the average of 1.26 inches for the month.
