As storms roared through Norman, Oklahoma, on April 22, lightning scattered across the night sky in stunning fashion.
Wet weather is forecast to return to parts of South America that have been dealing with drought, but even with some welcome rain on the way, AccuWeather forecasters say the rain is not all good news.
As a storm moves to the east, a front will stall over the region through the end of the weekend.
A storm meandering to the west of South America will begin to move east along the stalled front. This will help to increase precipitation across northern Argentina and Uruguay through the early part of this week.
Showers and thunderstorms are expected to develop from Chubut province in southern Argentina to the provinces of Salta and Formosa in the north. Precipitation will also expand across Uruguay and extreme southern Brazil.
According to Nicholls, the heaviest rain is forecast to fall from Río Negro to Córdoba and Santa Fe and east across Buenos Aires as well as Uruguay. Here, rainfall totals can reach 25-75 mm (1-3 inches) by the beginning of this week.
In areas that receive multiple heavy thunderstorms or extended periods of rain, an AccuWeather Local StormMax™ of 150 mm (6 inches) is possible.

"Locally strong thunderstorms that produce gusty winds and hail are possible in northern Argentina and Uruguay into Tuesday," added Jason Nicholls.
The rain will be welcome after an unusually dry end to the summer. Parts of northern Argentina recorded only 30-65% of their normal rainfall during the month of March.
Many cities have remained well below normal in rainfall amounts through the first half of April, including Buenos Aires, which has received only about 20% of normal rainfall so far this month.
However, the looming deluge may trigger flash flooding as well as delay the harvest for some crops.
While the rain will be beneficial to some, it may come at a cost.
Too much rain in a short period of time can result in flash flooding, especially in areas where the ground will be slow to absorb the influx of water.
The wet weather may also hinder the already struggling agricultural industry. Crop yield estimates have already decreased due to the ongoing pandemic, and now the prolonged period of wet weather could delay the harvest of some cotton, soybean and corn crops, according to Nicholls.
Even as the storm system moves away from the area into the middle of next week, unsettled weather can linger as showers and thunderstorms are forecast to linger in northern Argentina and Uruguay.
