Residents of São Paulo could face record cold and a return to hot weather in just a few days.
Starting this Wednesday (14), after a cold Tuesday, the polar air mass begins to weaken over the region, raising temperatures to around 20ºC, according to the Climate Emergency Management Center of the city of São Paulo.
Despite the milder weather throughout the day, dawn will still be in the single digits, with a minimum of 7ºC. Wednesday’s dawn could even break the coldest record of the year.
From Thursday (15), the heat returns to São Paulo, with temperatures around 27ºC.
Still due to the cold, on Wednesday (14) there will be frost conditions in areas of the Mantiqueira mountain range, between the south of Minas Gerais and the Paraíba Valley . The weather should remain stable, despite being cloudy in many regions of Southeast Brazil, according to Climatempo.
Weather in other regions
The sun promises to shine throughout the southern region throughout this Wednesday. The region remains under the influence of the polar air mass, with temperatures still low, but maximum temperatures slightly higher.
Frost is expected to whiten the landscape in the countryside and mountains of Rio Grande do Sul, on the western border of Rio Grande do Sul, in the mountains and plateau of Santa Catarina, in the valleys of Santa Catarina and in the south, center-east and in the Metropolitan Region of Curitiba.
In the Central-West, the weather is mostly stable in almost all regions. According to Climatempo, only in the extreme northeast and north of Mato Grosso, the formation of a low pressure center can favor the occurrence of isolated rain between the afternoon and evening.
In the states of Mato Grosso, central and northern Mato Grosso do Sul, Goiás and the Federal District, temperatures continue to rise sharply throughout the day. The highlights are the central and northern areas of Mato Grosso, including Cuiabá, where maximum temperatures are expected to exceed 35ºC. Only in the south of Mato Grosso do Sul, where the cold front is still in effect, the increase in temperatures is expected to be lower.
Instability in the North and Northeast
In the Northeast, the circulation of maritime winds should continue to favor the formation of rain along the entire coast of the region. These instabilities associated with a low pressure center in the interior of the continent should favor the occurrence of rain showers over the center and west of Bahia.
On the other hand, in the interior of Pernambuco, Ceará, Paraíba, Ceará, Piauí and Rio Grande do Norte, the weather continues to be stable and without rain. In these areas further from the coast, high temperatures and dry air continue to reduce humidity levels during the hottest hours of the day.
In the northern region of Brazil, heavy rains are expected throughout Pará, much of Amazonas, Tocantins, southern Amapá and Roraima, with precipitation intensifying with gusts of wind and electrical discharges. Thunderstorms may occur between northern Amazonas and southern Roraima.
In the extreme south and southwest of Amazonas, in the north of Roraima, in Acre and in Rondônia, the weather remains stable. As in the Center-West, there will be predominantly sun with little cloud cover during the day. Climatempo is focusing on the low humidity, which should reach warning thresholds during the hottest hours in the east of Acre and the center, north and south of Roraima.
