Okay all you road warriors, I need some help with my route heading from Denver to Eugene OR. It the "TIME" of the year I'm most curious about and WEATHER.
We'll be leaving out of Shawnee Oklahoma Sept 25th and well be traveling non-stop until we reach our destination. We'll be on I-80 to I-84 and what can I expect the weather to be on our route. Is it SNOWING that time of year?

I thank all of you in advance for your thoughts.

Just for clarification, since you mentioned I-80, that's about 100 miles north of Denver. Perhaps Cheyenne to Eugene? Unless you'll be coming up I-25 from points south to Denver, then on to I-80? If so, then take the US 287 route from Fort Collins to Laramie and bypass Cheyenne altogether.

I-80 across Wyoming should not be a problem in late September. However, the weather can be very changeable in Wyoming, so keeping an eye on it is a good idea. The highest point on I-80 will be between Cheyenne and Laramie, where it tops out at ~9600 feet. It's a gradual up hill to that point from Cheyenne, and there's a goodly downhill into Laramie. Just drop down a gear or two and it's fine going down.
