I'm going to say light turbulence for parts of the journey, and probably light-moderate nearer SLC and over DEN. SLC is getting 5 inches of snow, so I'd expect delays, and landing will be bumpy because of winds. A CRJ-900 is a bit smaller than a regular sized craft (say a 737 or A320).
However, you'll be perfectly safe. Just think of a bumpy country road.
Terrified of flying...could you give me a forecast? Thanks!
