When it's this cold in the upper midwest, it's going to be cold everywhere. I read somewhere the bowls played in Texas won't get above 50. Here in Minny it's about -14.
Yeah, if was going to be in the 40s in Iowa, it would be in the 60s in Memphis. Albuquerque, Charlotte, NYC, Nashville, and Annapolis of the top of my head all have outdoor bowl games and are as far north or farther than Memphis.
Late December seems to be the coldest down south. I've seen it 12 degrees in New Orleans on Christmas eve and frozen my butt off walking along a beach in a parka in Pensacola in December.
Unless you get a bowl in the Florida peninsula or Southern Cal, it's likely to be cold.
