On Friday they re-routed the big bike tour from RMNP to Ft. Collin to take 34 through Loveland and no smoke problems were reported. As you say, though, much can change this week and who knows which way the winds will be blowing the day you come through.

FWIW, we've had no smoke issues in Boulder so you may want to re-route your trip to go up to the park via Lyons.
