How is the drive in I-90 in Montana in SEPTEMBER?

I am planning to drive across Montana and parts of the Dakotas this September 2018.

Do I have to worry about the unpredictable weather of October for example if I go in September. Are the conditions in both months unpredictable or is September much better for driving? Will the driving have less traffic in September than August? What preparations should I make to drive in September? Please advise. Please include links to weather sites if possible. Thank you

The temps will be in the 40's - 70s. Traffic will be a bit less but highway traffic in Montana isn't much of a problem.

It should be fine in September as far as the Dakotas go. There are some high passes in Montana that "could" be a problem but not very likely.

Thank you very much.

Do you have additional comments about traveling through the area?

This might be one of the only chances I get to see Montana and the Dakotas; any suggestions?

Thank you

Excellent driving conditions in September.

Do you have time to detour down to Yellowstone? I'd definitely plan a stop at Little Bighorn -
