March 2015 was a very warm and dry month across central and northeast South Dakota as well as west central Minnesota.  Average temperatures were from 4 to 7 degrees above normal for the month.  The average high temperatures across the region were from 7 to 13 degrees above normal.  Locations in central and north central South Dakota were among the top ten warmest on record.  Pierre had their second warmest average high temperature for March along with Timber Lake.  Mobridge and Kennebec had their third warmest average high temperature on record.  There was a large range from the highest to the lowest temperatures for March with below zero readings early on to the very warm readings in mid and late March.  Differences between the high and low temperatures across the region ranged from 80 to over 100 degrees.  Kennebec had a difference of 102 degrees with a low of 19 below zero on March 5th and a high of 83 degrees on March 15th.

The area was also very dry throughout March with precipitation departures across the region generally from three-quarters to an inch below normal.  As a result, moderate drought conditions expanded across northeast South Dakota and west central Minnesota throughout March with abnormally dry conditions spreading out west.  Several locations had one of their top ten driest March’s on record.  Aberdeen and Mobridge tied for the tenth driest while Timber Lake had their fourth driest March on record.  Timber Lake and Mobridge also tied for their second and third least snowfalls on record, respectively, with only a trace of snowfall.
