Brazil Faces Persistent Cold in South, Low Humidity Across Interior

Southern Brazil will experience continued cold on Thursday, with widespread low humidity expected across the country's interior. While the cold air mass that has dominated recent days is set to weaken, frost is possible in parts of Rio Grande do Sul, Santa Catarina, and Paraná during the early morning. Much of the Center-West, Southeast, and interior Northeast regions will see stable, sunny weather with significant temperature differences between morning and afternoon. The National Institute of Meteorology (Inmet) forecasts relative humidity to drop between 20% and 30% in 14 states, potentially falling below 20% in some areas, particularly in the afternoon. This low humidity poses risks of skin dryness, eye discomfort, and respiratory issues. In the South, sunny skies will prevail with temperatures gradually rising to 20-25°C. The Southeast anticipates stable weather with a chance of early morning fog in coastal areas of São Paulo, Rio de Janeiro, Minas Gerais, and Espírito Santo. Minimum temperatures could approach 0°C in southern Minas Gerais and higher elevations of São Paulo, with frost possible in nearby mountain ranges. In contrast, northern Minas Gerais could see highs exceeding 30°C. São Paulo city expects a maximum of 23°C, while Rio de Janeiro and Belo Horizonte will experience highs around 25°C and 27°C respectively. The Center-West will remain dry and sunny, with afternoon temperatures reaching up to 35°C in northern Mato Grosso and Goiás, though mornings will remain cool in southern Mato Grosso do Sul, with lows between 5-7°C in some cities. Humidity levels in parts of Goiás, the Federal District, eastern Mato Grosso, and northern Mato Grosso do Sul could fall to 12-20%. The Northeast will see rain primarily along the coast, with irregular showers expected in Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, and Bahia, while the interior remains sunny and hot, with highs near 36°C. The North region will experience scattered showers in northern Amazonas, Roraima, Amapá, and central-northern Pará, with potential for thunderstorms in western Amazonia by Friday. Other areas in the North will remain dry and warm, with highs up to 36°C in southern Pará and Tocantins, where humidity may also drop below 30%.
