Wind chills in parts of North Dakota reached minus 70 degrees (minus 56 degrees Celsius), while the heat index in Miami was more than 160 degrees warmer at 92 (33 degrees Celsius).
The fun part of North dakota is the extremes. The record low (without wind chill) is -60 F, the record high is 122 F. That is a 182 degree spread, or 100 C spread for the rest of the world.
I often wonder how much money Northern states would save on roads if it weren't for the extreme temperature swings.
Regularly hit highs over 100 in the summer, lows below -30 in the winter. That's an awful lot of compression and expansion. Not to mention the abuse of heavy plows and their blades catching upheaved concrete.
It's wonder our roads look like they were shelled once spring rolls around. Last year was particularly bad, I don't think the roads were in decent shape until the end of the summer. At least near Minneapolis.
It's a little disingenuous to compare winter in North Dakota to Miami in this manner, and to include the windchill. I don't know the average temperature in Miami in January, but I do know that this is not "strange" for North Dakota in January.
I'm a Michigander. We don't get ridiculous low temps like -70 or anything but, I wish most roads would be left alone. Plow and salt main Highways and expressways but, leave everything else undone. Then we can buy vehicles that can traverse the snow like sleds or good 4x4 rigs.
This would keep our roads nicer and would keep our cars from rotting out
