Cool WX causing irregular flight tracks ND, SD, NE, CO area

What is usually this: … /KDEN/KFAR

Turned into this today: … /KDEN/KFAR

Still concerned about Frontier on the same route, DEN-FAR: … /KDEN/KFAR

Anything similar people noticed? This stuff is really cool to me.

They ended up diverting to YWG and refueling to continue to FAR. The original track disappeared so I uploaded it so people could see:
