The area has just withstood a prolonged siege of sub-zero temperatures. The low temps dipped to -3° below zero on February 6th and the lows stayed in the minus range until the morning of the 20th. For five days during that period, from the 12th to the 16th it did not get to zero or above with the coldest day being Valentines Day. The result can be seen in the picture of the Flandreau Dam. For the falls to be completely encased in a frozen cap of ice isn’t unprecedented but it has not been seen for a number of years.
Flandreau set a new record cold high temperature on Valentine’s Day of -13 which broke the old Valentine’s Day record of -11° set back in 1936. Likewise the low of -30 was a new record for February 15th, the old record being set at -25° in 1939.
As is typical this time of year, temperatures are quickly rebounding and this week it will be possible to see highs in the 40s.
