Both record cold and record snowfall in South Dakota

Also the earliest measurable September snowfall ever. To add to the misery, this all came after 100-degree temperatures on Saturday in Rapid City.

This was the earliest measurable snow in downtown Rapid City in September since 2014,  according to meteorologist Matt Gonterak. The city’s previous record of 1.6″ was set on Sept. 11, 2014 .

Tuesday’s weather set a record for a daily low in downtown Rapid City at 31 degrees. The previous record was in 1929 when downtown’s low was 34 degrees.

In fact, multiple records were set in Downtown Rapid City and at the Rapid City Regional Airport on Monday September 7th, 2020:
