Friday will witness instability in the southeast, especially in Minas Gerais, where the combination of heat and humidity keeps heavy clouds forming throughout the afternoon. In Rio de Janeiro, the chance of rain increases in Sul Fluminense and Serra, while the coast continues to receive faster and more regular rain. In São Paulo, the Paraiba Valley and the northern coast focus the greatest risk of rainfall, but with periods of sunshine between openings.

– Conditions remain favorable for storm formation, especially in Minas state and south of Rio. Meteorologist Andrea Ramos says the weather is organized for this purpose, noting that moisture is still directed towards the southeast.
Temperatures remain high in the region, with maximum temperatures approaching or exceeding 30°C in the interior of São Paulo and Minas Gerais. The heat increases the possibility of wind gusts and thunderstorms, a scenario that could be repeated later in the day in warmer areas.
In the central-western region, instability increases in the north of Mato Grosso, where more heavy rains are expected in the afternoon. More local rain falls in Goiás and Mato Grosso do Sul, depending on the temperature of the day.
– Even in states with irregular instability, there is a possibility of wind gusts when rain cells form – says Andrea, explaining the typical behavior at this time of year.
The north remains the most affected region. Amazonas, Acre, Rondonia and Pará have large areas with a high probability of rainfall, with thunderstorms forming between the afternoon and early evening.
– The weather is very humid and hot, which encourages widespread and persistent storms in several places – says the meteorologist.
In the northeast, Bahia again concentrates the most significant quantities. The west and south of the state continue to record high accumulations since the beginning of the week, and on Friday the pattern of dense skies and frequent rains is maintained. On the coast, instability is weaker, but still present.
In the south, Friday will witness a state of instability limited to the coast of Santa Catarina and eastern Rio Grande do Sul. Inland areas will once again see low temperatures and humidity, with less potential for isolated storms.
Trend for the weekend
Inmet maps show that Saturday (30) maintains instability centered in the north and part of the Midwest, with more frequent rains between Mato Grosso, Tocantins, Pará and Amazonas. In the south-east, Minas Gerais remains the area most at risk, with rain falling in the afternoon and at night. In Rio, Sol Fluminense maintains the possibility of instability; In São Paulo, the coast and Paraiba Valley will again see rain in the late afternoon.
In the south, the southernmost tip of Rio Grande do Sul appears again with the possibility of heavy rain on Saturday, while the rest of the region remains under the influence of heat.
Andrea Ramos explains that the change in pattern should happen on Sunday.
– Between Sunday and Monday, there is a tendency to form a more organized system, capable of increasing the risk of heavy rain in some areas – says the meteorologist.
