A roller coaster week of weather is predicted for Argentina, Paraguay, Uruguay and southern Brazil. There will likely be a combination of extreme heat, followed by a rapid cooldown with rainstorms here and there. If you don´t like the weather, just wait half an hour.

The beginning of spring is upon us in the Southern Hemisphere, and Argentina and southern Brazil will experience some early summer weather as unusually warm weather builds.

A flow of balmy, tropical air from the north will help reach temperatures up into the 30s Celsius (mid -80s to near 100 Fahrenheit) in many places during the week. Specifically, Buenos Aires, Argentina, will peak at 32C (90F) on Tuesday, a whopping 14C above normal!
