A cold front brought gusty thunderstorms with locally heavy rainfall to parts of northeastern Argentina and Uruguay on Tuesday, and another front will bring a renewed threat for strong to severe storms Thursday into Thursday night.

The cities of Buenos Aires and Montevideo will again be in the path of these storms, which will be capable of producing damaging winds, locally heavy rainfall and hail.

A brief break from the stormy weather occurred on Wednesday as the first frontal boundary lifted north into Brazil promoting a cooler and dry day across the region.

The second frontal boundary will bring a new threat for strong to severe thunderstorms Thursday afternoon and evening for both Buenos Aires and Montevideo.

The second front will lift northward by Friday allowing a much cooler air mass to push into both cities through the weekend.

Meanwhile, the threat of heavy rain and gusty thunderstorms will shift into areas from Paraguay into southeastern Brazil for the weekend where flooding will be the primary concern.
