Hi all,

I'm considering a month-long road trip, and am wondering if this route might prove too cold (read: snowy) to take in my FWD sports coupe. I ask because I've never been in certain parts of the country in October, and despite a bit of weather research, have no clue what to expect. My route is:

Day 1: Philly to Chicago (long haul, I know, but I've done longer)
Day 2: Chicago to Milwaukee
Day 3: Milwaukee to Minneapolis
Day 4:Minneapolis to Fargo
Day 5: Fargo to Rapid City
Day 6: Rapid City to Missoula, MT
Day 7: Missoula to Seattle
(A week in Seattle, then south/Midwest back to Philly).

What should I expect weather-wise? I'll bring clothes that'll fit that kind of weather, but I ask because my tires are straddling the line between "decent tread" and "worn." Likely I'll change them before I leave anyway, but it'd be nice to know what October's like for those aforementioned parts of the country.

Thanks much.
