I'm confused. It's spring in the northern hemisphere.
It's Spring but there's a winter airmass around and it got stuck in the Caynon with warm air coming over top of it. I think they mentioned Winter because it would only happen in winter if it does? Or maybe just because this is an unusual winter airmass there for late Spring.
There are definitely smaller inversion events there, but they usually come on cloudy days or only fill part of the canyon. This filled the entire canyon on a clear day which was a rare sight.
For those not sure... clouds are created when cold air is trapped near the surface as warm air moves in above. The humidity in the colder air causes the fog. Inversion means warmer temps as you go higher in height.
Jet stream dipping to Mexico border with cold airmass north of it. Not sure where the warm air came from. Probably the Mid May Sun? Pacific air with the cold air trapped?
Big snowstorm for some areas of Wyoming and Colorado which are leafed out too. Point is, winter type pattern

Hmm; I wouldn't have thought it'd be a winter-only pattern. Need a source of cold + some moisture to create the pattern? It'd be neat to see the vertical temperature profile there; I wonder if the Grand Canyon occasionally gets unusual ones.

Either way, they can just call it a "rare spring phenomenon"...
It's still winter there? Looks like these people don't even know the season of their country...
The south rim of the Grand Canyon is at 7000 foot elevation. The calendar may say spring, but at high elevations the weather can still be wintery.
