Today, Guadalajara, Mexico is covered in 5 feet of ice from an enormous hail storm. July 1, 2019

Tropical Storm Barbara (click here) is set to become the next hurricane in the Eastern Pacific Ocean and take a track farther to the west than Alvin.
Less than 48 hours after the demise of once-Hurricane Alvin, Barbara formed over the warm waters several hundred miles to the southwest of Mexico on Sunday.
Further strengthening is expected as Barbara remains over warm water and in an area with lessening wind shear, both of which are conducive for a tropical system to intensify....

This is the height of the mixing. It is definitely over Guadalajara.
Hurricane season is beginning in the East Pacific. There was a rapid change in equatorial water vapor at the end of Alvin and the spawning of Barbara. The Southern Hemisphere is also turbulent. There is a huge water vapor plume from Indonesia south to Antarctica at the same time there is air mixing over Mexico.
This is definitely a global climate event. Five feet of hail is rare. I don't recall such events in the past 20 years at the very least.
Basically, the skies over Guadalajara opened up and upper atmosphere cold air mixed with water vapor and the rain turned to ice.
