I am glad that John and Earl posted before I could. I have lived and worked in North Dakota, Colorado and Northern Illinois as well as Texas. 35 degrees in east and southeast Texas with the wind blowing is sort of equivalent to 15 below in Durango (I have cut wood outside in Durango in short sleeves at zero), about the same in Northern Illinois, and feels about the same as 10 below in North Dakota with the wind chill at -20. Below that North Dakota with the wind blowing is definitely colder.
When I had relatives living outside Durango, it always seemed colder in my driveway in Houston at 40 than up at Lake Vallecito at -10 the day before.
