A cold front is moving through the Southeast this Thursday (3) and organizing areas of instability over parts of the Central-West, Southeast and Northeast, with more intense rains between northern Minas Gerais, Esp\u00edrito Santo and southern Bahia. The cold air mass also reduces temperatures and may cause frost in the Serra da Mantiqueira and Paran\u00e1, while another system increases the risk of hail in Rio Grande do Sul.\n<\/p>\n
The passage of the cold front establishes a channel of moisture over these regions and favors isolated showers. In the South, a low-pressure system passing south of Rio Grande do Sul contributes to rainfall and increases the possibility of hail in southeastern Rio Grande do Sul.<\/p>\n
In the Northeast, however, the heat remains intense inland, with temperatures that can exceed 40 \u00b0C.<\/p>\n
In the North, Thursday will be marked by many clouds throughout the region. Showers are expected in the central-west and northern Amazonas throughout the day and, in isolated areas, in southern Tocantins and Par\u00e1.<\/p>\n
In other areas, there is also a possibility of isolated rain. Among the capital cities, the lowest minimum temperature will be 23 \u00b0C in Rio Branco (AC). Maximum temperatures will reach 37 \u00b0C in Manaus (AM) and Rio Branco, and 38 \u00b0C in Porto Velho (RO) and Palmas (TO).<\/p>\n
There is a yellow warning indicating potential danger due to low air humidity in southern Tocantins.<\/p>\n

Manaus and Palmas will register maximum temperatures of 37\u00b0C.<\/p>\n
