Go South For Snow, Waaaay South

An area of low pressure that formed in northern Mexico during early March was unusually strong and cold for that area, not only for March, but anytime of year.
"Such a large, strong upper low appears to be an unprecedented event in modern weather observations for Mexico," said Bob Henson in a wunderground.com blog.
As the above satellite image illustrates, snow fell throughout Mexico's Sierra Madre Occidental Mountains. However, some high-valley locations even saw snowfall from this storm system.
Mexico's second-most populated city, Guadalajara, even saw a coating of snow in some areas. Guadalajara is at a latitude lower than Miami and even Havana, Cuba. However, its elevation of about 5,200 feet in combination with the cold nature of the low pressure system allowed snow to fall there. This is reportedly the first snow in Guadalajara since December 1997, another strong El Nino year.
