I came across some interesting data today. The last time Sioux Falls had an overnight low temp above zero was December 28th when the low was 4°. During that time, the warmest low Sioux Falls has had was 0° on January 3 with the coldest low being -18° on January 6th. Our current ten day stretch, is giving Sioux Falls an average low temperature of -8.4°. This string should end later this week.
I also checked the stats for other cities in eastern KELOLAND, but I found that many locations had an above zero low on January 4th. This includes Marshall, Pipestone, Brookings, and Huron. I did find that Aberdeen and Watertown also in a consecutive string of below zero lows, but it’s a day longer than Sioux Falls.
Aberdeen’s last above zero low was December 27th when the low was 15°. Since December 28th, the coldest low is -27° on January 2nd while the warmest low is 0° on January 3rd. The average low for December 28th through January 7th is -13°.
Watertown’s last above zero also occurred on December 27th, with a low of 14°. The average low since December 28 is -13°, just like Aberdeen. It includes a coldest low of -27° on January 2nd and a warmest low of -4° on January 3rd.
I’ve included tables of all three cities below.
