Numerous New Records for Cold Low & High Temperatures February 13-15, 2021

The coldest air began to spread into the region on Saturday, February 13th, resulting in a few record cold high temperatures.

Valentine’s Day 2021 became the coldest on record since 1936 for several locations, easily breaking the record cold highs by several degrees.

These records are preliminary, but they illustrate how extensive the cold air was, especially from Valentine’s Day into the following night & early morning of the 15th, when record low temperatures were broken or tied in many of the same locations which saw record cold high temperatures the day before.

The cold snap started to ease by February 16th, but not before a few more records were tied/broken.

All in all, the preliminary data shows 22 sites in southeast SD, southwest MN, and northwest IA, with 1 or more new records, with 14 of those sites setting multiple new records from Feb 13-16, 2021.
