Wetter and Colder February 2009

 

The month of February across central and northeast South Dakota as well as west central Minnesota had several large precipitation producing systems affect the area.  These systems were enough to bring the month of February above normal precipitation and snowfall for most locations across central and northeast South Dakota along with west central Minnesota.

 The first storm system in early February was quite unusual in that it was warm and produced mostly rain and quite of bit of rain especially for central and north central South Dakota.  Several locations had an inch or more of rainfall from this storm.  Mobridge had 1.28 inches of rainfall from February 8th to the 9th.  The other systems came at the end of the month and brought large snowfall amounts across central and northern South Dakota into west central Minnesota.  Snowfall amounts from 6 to as much as 14 inches were reported with the February 26th and February 27th storms.  February snowfall amounts ranged from near normal to over 10 inches above normal.  Sisseton, Wheaton, and Mobridge all had around 16 inches of snowfall for the month.  These snowfalls ranked as the 4th snowiest February at Wheaton and Mobridge, the 7th snowiest at Sisseton, and the 11th snowiest February at Timber Lake on record.   As far as total precipitation, the 1.87 inches at Timber Lake was their 3rd wettest February and the 1.01 inches at Pierre was their 15th wettest February on record.  Pierre and Mobridge also set daily maximum precipitation records on the 9th.

The temperatures for the month of February continued the trend of below normal across much of north central and northeast South Dakota along with west central Minnesota.  Temperatures ranged from 2 degrees below to as much as 7 degrees below normal for the month of February.  Again, Kennebec and Pierre were near to above normal for temperatures.  Kennebec set a record high of 64 degrees on the 6th.   The snow cover continued to play a role and keeping the northern and eastern parts of the area colder than normal.
