A Cold Start to June

Early June has started out abnormally cold across the area culminating in near record cold daytime temperatures in Sioux Falls, Huron and Mitchell on June 6 and 7.  While temperatures remained in the 50s this past weekend, the normal high temperature yesterday for all three sites was 78.  The recent cold weather has been the result of a strong high pressure over southern Canada bringing cool and dry air into South Dakota combined with a dense cloud cover and light rainfall.  Below is a listing of records which compare the unseasonably cold temperatures on June 6 and 7 to past years.
