Wind Chill History: When Did We Last Experience BRUTALY COLD chills?

Because I like colorfully displayed data that tells a story, I tabulated the TOTAL HOURS where we experienced WIND CHILLS BELOW ZERO for each winter recently using the IOWA MESONET SITE.

The last winter with wind chills -6 to -10 was 2018-19

The last brutally cold winter of 2013-14 featured wind chills under -30

So far this winter (2021-22), none yet.

I included some of the cold winter of the late 1970s/early 1980s for comparison
