Thinking back historically, what is I80 like during the 1st & 2nd week of December? -weather-wise...
I don't have a historical record for I-80 or that region of the country. I do know that there have been heavy snows experienced at times in the midwest in December. You are definitely in winter storm territory and my only advice here is to watch the long term (Weather Channel weekly) forecasts. The weather could be quite nice or you could encounter highway closings due to heavy snow or ice. In your motor home you are much better equipped to face the consequences of closed highways than other motorists. You have your motel with you and can conveniently wait out bad weather. People do travel all these roads all winter long. If you aren't on a have-to schedule, you can take your time and work your way along as the weather permits.
As mentioned above, I am planning to be leaving Olympia/Seattle, WA headed East on I-90 this time next Monday. If weather looks questionable for that route I could drop south and take I-84 to I-80. This illustrates another way to handle storms, if you don't want to wait them out, travel where the storms are not going to affect you, change your route. I will be on a schedule that will require about 400 miles a day to reach the St. Louis area by Friday so I'll be looking to get some road behind me each day. If we fall behind one day, we'll try to make up some of it the next day. This time of year, the options are more open than they may be in December.
By the way, your note brought back to me the name of a magazine I had forgotten. Weatherwise is a publication of the American Meteorological Society. I found their web site thanks to your use of the phrase. If you are interested in weather, this magazine features great stories about weather and also has some incredible photos. Unfortunately there is only a print version available though the archives can be searched electronically. I don't know if you can download reprints or if they have to be mailed. I'll be looking into that.
I just did a brief search and found an abstract of a 2010 article, "When Winter Comes to Fall." It described a snowstorm that hit the Denver area the end of October. Up to four feet of snow fell in the foothills and I-70 was closed for a period of time. That brings to mind a late fall trip to Colorado we made in 2005. It was the second week of November before we were ready to leave the Denver area. We pulled up stakes late one afternoon with the forecast of a storm on the way. We stopped at a rest area north of Colorado Springs. I got up at 5:00 a.m. and turned on the Weather Channel to see the storm coverage from Denver featured on the morning show. The radar showed the snow just north of our location and moving our way so I woke Louise and we did an emergency - get out of town - drill and were on the road in about 5 minutes. We stayed ahead of a pretty good snow storm that time. Any time I'm traveling in late fall or winter I am always watching the weather!
