Sounds like a Navy PCS move........
........and please accept my thanks for your service, also.
Hello crystalfrison,
If this were my trip, my intense bias against large cities and their traffic would make me look closely at avoiding DC and Chicago, provided doing so didn't add too much distance. The alternate I'd map out for comparison with my friend glc's route would be I-64 all the way from the Beach to Lexington, KY, I-75 to Cincy, I-74 to Davenport, IA, where you'd pick up I-80. Then I-80 to I-29 north (using the I-680 shortcut just east of Omaha, of course) to I-90 on the eastern border of SD at Sioux Falls. You do pick up Cincy and Indy as cities that way, but my feeling is they're a good trade for the God-awful morasse of DC and Chicago.
As glc noted, you'll just want to continue to look ahead at what the weather's doing about a day ahead of your route. Once you get to central MT, you start going through a series of passes at Bozeman, Butte, the ID border, and finally Snoqualmie Pass in WA just east of Seattle. What you can avoid by continually looking ahead is driving right into the teeth of a storm. The storms usually pass quickly and the plow crews and their equipment are the best anywhere in the world, so normally everything's squared away within a few hours of a storm.
Also as glc noted, the Mountain states have live webcams liberally scattered along the Interstates, so you can search them up and have a look at conditions at the passes and elsewhere along I-90 in particular. Practically every travel plaza (the new term for truck stops) has TVs constantly on the Weather Channel if you're not smartphone or laptop-equipped.
Glad to learn of your Navy Reserve service, glc. I knew we got along well, but never the underlying reason why. My "baby" son, all 6'3" 220 lbs of him, is a Seabee, you may recall. He's now in the Reserve. I love the Navy and everything it did for my son.
Safe travels crystalfrison.
