I understand the gist of your point, but disagree in this instance. It’s mid January…not early December. CON snuck an 8° in the other day while I stayed mixed and had a min of 11°, but their latest sub 10° on record is 1/16.
DFW has been below 10° once since 1996. BNA has been below 10° once since 2018.
We’re not talking Amarillo here.
