After a few dry days, northeastern Argentina and Uruguay could be facing flooding problems for the weekend.
A front lifting northward across the country of Argentina throughout the weekend will bring some heavier thunderstorms.
Late Saturday afternoon and into Saturday evening, thunderstorms will begin to develop along this front, bringing drenching downpours for Buenos Aires and Cordoba in Argentina. Into Sunday, thunderstorms will move into Montevideo, Uruguay and southern Brazil.
The main threat with these thunderstorms is expected to be the heavy rain. As the front slowly pushes northward, enough water could fall from the sky to cause flooding. Rainfall could reach as much as 50 mm to 100 mm (2 to 4 inches) through Sunday. Even higher amounts could be possible in a few locations.
Although the main risk is flooding, heavy rain will not be the only threat. AccuWeather Meteorologist Rob Miller said, "there could also be some isolated wind gusts reaching 80 kph (50 mph)" as the front passes.
The rain will also bring a cooldown for the area. Leading up to these storms, temperatures will be reaching near 30 C (about 85 F). The arrival of the clouds and heavy rain will bring temperatures back in the low to mid-20s C (low to mid-70s F). These cooler temperatures will likely hold through Monday and Tuesday.
