The presence of a low-pressure system near Paraguay continues to maintain the possibility of showers over part of northern Rio Grande do Sul, western Santa Catarina, and especially the state of Paraná. Rain may begin in the morning in western and northern Paraná, ranging from moderate to heavy. During the afternoon, these instabilities spread across the northwest and north of the state, with a risk of lightning and winds of up to 70 km/h. Eastern and coastal areas of the state begin the week with clearer weather and the presence of medium clouds, but without rain. In Santa Catarina and northern Rio Grande do Sul, the circulation of moisture stimulates localized showers during the morning and afternoon, easing in intensity at night. In other regions, the weather is already clearer and more stable. Some cities in the west and the Missions region of Rio Grande do Sul state can already expect a more significant increase in daytime temperatures.
In the Southeast, the week begins with low humidity – the weather will return to dryness, with warnings for URA values between 20 and 12% across the north and northwest of São Paulo, the Triângulo region, and the west and northwest of Minas Gerais. Rain is not forecast in the region's capitals, and in São Paulo, it will heat up further in the afternoon. On the coast of Rio de Janeiro and Espírito Santo, moderate winds are expected, with gusts of up to 50 km/h. In the afternoon, areas of western and southwestern São Paulo are on alert for moderate to heavy rain, due to the combination of heat and humidity.
In the Central-West region, instability remains present in some regions of Mato Grosso do Sul, still quite irregular—but with a warning threshold for moderate to heavy rainfall in areas of the south-central and southwest. Rainfall weakens in Mato Grosso, but remains present in areas of the extreme northwest of the state, varying between light and moderate intensity. In other regions, the presence of dry air prevents rainfall, and relative humidity is entering a state of emergency in northern Goiás and part of eastern Mato Grosso, reaching values below 12%. There is no rain in Cuiabá, Brasília, and Goiânia, with a notable increase in temperatures.
In the Northeast, instability remains concentrated in a few coastal areas—rain in the form of isolated showers in eastern Sergipe and Alagoas—the week begins with muggy weather and caution in Maceió. In other regions, the weather remains stable, with mostly sunny conditions during the day. Temperatures are expected to rise further in Maranhão, Piá, western and northern Bahia, inland Pernambuco, and Ceará, while humidity plummets in the afternoon, with values ranging from 30 to 211 TP4T.
In the North, instability remains present in Amazonas, Acre, Rondônia, and Roraima. There's a risk of some storms in northwestern Amazonas and heavy rain in Rio Grande do Norte, Acre, and northern Rondônia. In other regions, heavy showers are possible at intervals throughout the day. Pará may experience isolated showers in areas bordering Amazonas. Amapá and Tocantins will experience clear weather during the day, with sun between some clouds and increasing heat as the hours pass. Humidity levels are entering a state of emergency in southern Tocantins, with values below 12%.
