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

What is usually this:

flightaware.com/live/flight/SKW6 … /KDEN/KFAR

Turned into this today:

They’re almost in Canada! When will they just divert already???

Still concerned about Frontier on the same route, DEN-FAR:

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:
