I-90 East Travel Between Spokane, Wa and Billings, Montana

I agree with Corky - Would dance in the street if it rained hard. Missoula is supposed to be getting some rain today and tomorrow (Kalispell, not so much). However, you never know. Anything can happen. I'd suggest you check the webcams just before you leave. Access it at the MT gov website - highway dept. Good resource. Have a good trip.
