Cold front advances with heavy rain and drop in temperature in RS, warns MetSul

A MetSul Meteorology warns that a cold front will advance through Rio Grande do Sul this weekend with rain that will be heavy in several cities and still with the risk of some isolated storms. There will also be a sharp drop in temperature, due to the arrival of colder air after a hot Saturday in part of the state of Rio Grande do Sul.

The cold front brings rain between dawn and morning to several parts of the West, Campaign and South of the state. The risk of heavy to torrential rain with excessive volumes in a short period is high, which can cause flooding and flash floods.

There is a chance of localized storms with lightning, wind and hail. The front will then move to the Center and North of the state from the afternoon to the evening this Saturday, where the sun appears first with heat and a North wind.

The wind, due to the relief, can raise the marks on the thermometers to values ​​of 33ºC to 35ºC in the valleys. The cold front, upon encountering warm air as it moves through Gaucho territory in the second half of the day, will have heavy clouds capable of causing locally heavy rain and isolated thunderstorms in which the possibility of hail and localized gales cannot be ruled out.

Sultry Saturday in Porto Alegre

In Porto Alegre, Saturday will have sun and clouds with heat and stuffiness. The temperature can be close to or reach 30ºC. The cloudiness will then increase and the weather will become unstable with rain.

It rains more from the middle or end of the afternoon and at night, continuing at the beginning of Sunday. A strong wind will not move away when the cold front arrives in Greater Porto Alegre later today and there is a risk of heavy rain, especially between Saturday night and the beginning of Sunday in the Capital and the metropolitan area.

Saturday will end with temperatures of up to 13ºC to 14ºC in cities on the border with Uruguay, Campanha and the South of Rio Grande do Sul, before a cold dawn in these regions on Sunday.

Throughout next week, Rio Grande do Sul will be between colder air to the south and a powerful mass of hot air over Brazil. Depending on the day, sometimes warmer air advances from the North to the state, and sometimes colder air will move from the South to the Rio Grande do Sul territory. Since it will be in the transition zone between the two air masses, hot and cold, instability will be frequent with the expectation of a lot of rain.

Hail and storms in Uruguay

Strong storms hit Uruguay with the encounter of a mass of hot air with colder air. The storms hit different departments of the neighboring country with reports of hail, up to 8 centimeters in diameter in some places, and some windstorms.

In Solís de Mataojo, Lavalleja, large hailstones fell. Some hailstones were the size of a hen’s egg. “The noise from inside the houses was impressive. There were dented cars and broken windshields,” a local resident told Montevideo newspaper El País.

Hailstorms also hit the towns of Las Piedras (Canelones) or Kiyú (San José), causing damage to roofs. There were records of isolated hail in sectors of Northern Uruguay close to the border with Rio Grande do Sul.
