Contest of Champions on Urithiru

[theSurgeOfPhysics Awakened Object]

The Stormfather said that a Highstorm naturally cycles higher and lower in the sky and will at the highest point engulf the top of Urithiru. The last Highstorm we saw was at end of RoW, a few days before the end of the book yet before the 10-day countdown began, and Kaladin described it as being just below the rooftop. So in 10 days, the Highstorm will likely envelop the rooftop and make for a great battle scene!

The timing of the contest is important, as the Stormfather may be able to extend time in Dalinar's last moments of the fight (if Dalinar does indeed serve as his own champion). He may ask for this if, say, he becomes severely wounded. It would be very interesting to see Dalinar take a pause in the fight and be able to think it through, and given the additional Investiture from the Tower (and potential Investiture from the Valley if the Highstorm lines up with both locations simultaneously— see linked topic below), then he'd have a lot of time to work with.

The only problem is that Odium set the date and time of the contest, and he probably knows when the next storm will be, so does he want a Highstorm for the contest? If so, why? Perhaps Odium has done this so that he can command the Everstorm to meet with the Highstorm at this moment, causing a WoR-level phenomenon that we saw before. 

This is just speculation, so maybe we won't see any Highstorm, but we've seen either a Highstorm or the Everstorm used in the last battles since WoR, so it would only make sense for us to see them used again.

Given the amount of control the Stormfather has over the storm he could probably bring it there at the time.

Though your mention of the storms reminds me of this one death rattle
