Temperatures start to rise this weekend in the Southeast, says meteorologist

As a polar air mass near Brazil loses intensity, temperatures in the South and not Southeast should start to increase this weekend, according to Climatempo meteorologist Maria Clara Sassaki.

In an interview with CNN this Saturday (21), she stated that the trend in both regions in the coming days is intense cold during the night and dawn and after temperatures higher in the afternoon, generating a large thermal amplitude.

The weekend in the South should start “cooler, that autumn look, temperatures below 10º C, but in the afternoon the feeling of heat increases a lot, and the thermometers can reach 25º C, 26 ºC”.

According to Sassaki, the thermal amplitude is generated by dry air, which should predominate in much of Brazil. The South should still have frosts, but less intense and more restricted to mountainous areas in the Rio Grande do Sul and Santa Catarina and some isolated points on the Paraná border.

This large temperature difference is indicative of dry air, as the air is very dry in the South and in most of Brazil, we have a large temperature range, with colder nights and dawns and higher temperatures in the afternoons.

The polar air mass also lowered temperatures in the North and North East , with frosts in states like Rondônia, Acre and Tocantins and cold winds in Bahia. Now, a cold front is approaching Bahia, still far out in the ocean, which should generate cloudiness in the state and in some neighbors.

“It is the same cold front associated with the subtropical cyclone that passed through the South and Southeast of Brazil last week, now it passes through Bahia and leaves heavy clouds in the region. Rain is expected at any time, between the Recôncavo Baiano and areas of Pernambuco, it may rain in Rio Grande do Norte in the late afternoon,” he says.

From Ceará to Roraima, rain showers are expected at any time of the day, which can be of high intensity, with temperatures close to 30º C. In the range from Acre to Bahia, dry weather predominates, and the temperature should also get high.

“In the Southeast and Midwest, the highlight is dry air and low levels of relative humidity, with more open weather conditions in most of these regions, but we will still see a lot of cloudiness in São Paulo, an effect of the fog that formed throughout the night, there are still many clouds, but the tendency is for the sun to appear in the afternoon, with conditions of higher temperatures and wide thermal amplitude”, he says.

The forecast for the capital of paulista this Saturday it has a maximum of 21°C and lower humidity levels, close to 35%. The day will end with stable and dry weather.

Sunday (22) should start with lots of clouds forming humid mist. Even in the morning, the sun appears and predominates for the rest of the day. Thermometers fluctuate between 11°C at dawn and 23°C in the afternoon.

Monday (23) will have potential for formation of wet mist and fog between dawn and early morning hours. In the morning, the cloudiness dissipates and the day becomes sunny. Because of this, the temperature presents a rapid rise, with a minimum of 11°C and a maximum of 24°C.
