Warmer Than Normal April

 Another above normal temperature month occurred across central and northeast South Dakota as well as west central Minnesota.  Temperatures for April were from 4 to nearly 8 degrees above normal across the area.  The warmest daily temperatures for the month were in the upper 70s to the lower 80s in the middle of April.  Along with these warm temperatures, very strong south winds from 35 to 45 mph gusting to 60 to 70 mph occurred on April 13th.  The wind and warm temperatures also helped several fires to spread.  

The precipitation for April was near to above normal which was not good for the ongoing flooding situation, especially in northeast South Dakota.  Snowfall was pretty much non-existent for the month except for west of the Missouri River in north central South Dakota. Towards the end of the month, a large upper level low pressure area brought showers and thunderstorms to the region with rainfall amounts ranging from a quarter inch to over two inches in some locations.  In Brown County, Aberdeen received nearly 2.25 inches or rain over a two day period adding to the expansive and damaging flooding already occurring.
