Weather forecasts indicate significant changes in the coming days across various parts of Brazil. While a frontal system will bring rain to the Northeast and part of the North Region, the rest of the national territory is expected to maintain stable weather, with cold early mornings and alerts for frost and low air humidity.
Rain returns to the Northeast
The main climatic change will occur in the Northeast. According to Inmet data, a low-pressure system over the Atlantic Ocean is organizing a frontal system that will intensify precipitation between the southern coast of Bahia and Alagoas, with higher incidence expected on Wednesday (15). This instability will also extend to areas of Ceará, Piauí, and Maranhão.
On the southern coast of Bahia, specifically between Itacaré and Porto Seguro, there is a coastal wind warning valid for Tuesday (14). For Wednesday, the risk of strong winds covers areas of Bahia, Pernambuco, Sergipe, Alagoas, southern Ceará, southern Paraíba, and the border between Piauí and Pernambuco. Despite the return of rain, the interior of the region will remain hot, potentially recording temperatures up to 35°C, although in the mountainous areas of Bahia, minimums will be around 15°C.
Instability concentrated in the North
Amazonas, Pará, and Roraima have the highest probability of rain on Tuesday (14), with expectations of isolated showers and thunderstorms. On Wednesday (15), the instability will remain more focused on Amazonas and Pará, while other states will record scattered rain. Acre, Rondônia, and Tocantins are expected to experience predominantly dry weather during most of the period, although northern Tocantins may have localized rain.
Key points of the forecast include heavier rain in Bahia, Alagoas, Ceará, Piauí, and Maranhão; isolated thunderstorms in Amazonas, Roraima, and Pará; frost forecast in regions of the South, southern Minas Gerais, and Campos do Jordão; and low air humidity in municipalities of the Center-West and interior of Southeast.
Cold in the early mornings of the Central-South
Residents of the Southern Region will face another night of low temperatures on Tuesday (14). A cold air mass will keep thermometers between 0°C and 4°C, favoring the formation of frost in Paraná, Santa Catarina, and Rio Grande do Sul. On Wednesday (15), the intensity of the cold will decrease, allowing maximums to exceed 20°C in several cities.
In the Southeast, mornings will remain cold, especially in southern Minas Gerais and Campos do Jordão, where frost is still predicted. Light and isolated rains will be limited to the coast of São Paulo and Rio de Janeiro, as well as northeastern Minas Gerais.
Center-West with little variation
For the Center-West, the forecast indicates few changes. There is a possibility of isolated rain in the Federal District and Goiás on Tuesday (14), and in the extreme north of Mato Grosso on Wednesday (15). The most notable aspect remains the low air humidity in Mato Grosso do Sul and southern Goiás, whose indices may vary between 20% and 30% during the afternoon.
In summary, the country will present a scenario of contrasts in the coming days: while the Northeast and North will see the return of rain, the South, Southeast, and Center-West regions will be marked by the persistence of cold and dry weather.
