As the final week of summer begins in Rio Grande do Sul, temperatures are anticipated to soar, with several cities expected to reach 35ºC or higher. The weather forecast from Climatempo Meteorologia indicates that a dry air mass will dominate the area, ensuring mostly clear skies and increasing temperatures throughout the day. In particular, cities like Alegrete, Cachoeira do Sul, and Santa Rosa are among those likely to experience these extreme temperatures, with some inland areas potentially hitting maximums of 37ºC.

The conditions will change later in the day as the combination of heat and humidity, alongside a low-pressure area, is expected to bring about some instability in the weather. Rainfall is predicted, particularly affecting the regions known as Missões, Pampas, and Noroeste, which may experience moderate precipitation. The southwestern zone could encounter stronger and more irregular rainfall, suggesting a notable shift from the earlier dry spells during the day.

Overall, the fluctuation between the sweltering heat and the possibility of rain reflects the typical transitional weather patterns in the region as summer comes to a close. Residents should prepare for both the extreme heat earlier in the day and potential downpours later, a combination that underscores the changing dynamics of seasonal weather in southern Brazil.
