Severe Weather To Target Brazil, Paraguay, Bolivia

Severe thunderstorms will threaten parts of Brazil, Paraguay, and Bolivia Friday and Saturday. Damaging winds, large hail, and flash flooding are all concerns.

The Setup

A cold front will move northward across central South America on Friday. Along and ahead of the front, the environment will be supportive for some damaging thunderstorms to blossom.

The greatest severe threat Friday afternoon and evening will extend from southern Brazil northwestward through Paraguay and into Bolivia. This includes cities such as Florianopolis, Asuncion, and Santa Cruz.

Damaging winds in excess of 80 kph, large hail up to 5 cm, and flash flooding will be possible in the strongest of storms.

The severe thunderstorm threat will diminish late Friday night into early Saturday, however, the severe threat will once again grow during the day Saturday as temperatures rise ahead of the cold front.

Cities such as São Paulo up to Brasilia will be at risk for some gusty to potentially severe thunderstorms Saturday afternoon and evening.

In the wake of the cold front, a cooler more stable fall air mass will move in and end the risk for severe weather.
