Most regions of Brazil are expected to experience sunny weather this weekend, according to weather forecasts released Friday [1].
This shift toward warmer, drier conditions follows a period of instability and rainfall in several states, affecting agricultural planning and weekend travel across the country.
Temperatures in most capital cities are expected to rise above 30°C on Friday [1]. This trend marks another phase of a "veranico," a period of unseasonably warm weather [1].
In Alagoas, the Secretaria de Meio Ambiente e Recursos Hídricos (Semarh) said that a dry air mass began to predominate on May 27 [2]. This followed a period where Semarh said there was the possibility of passing showers in the Zona da Mata and along the coast until May 26 [2].
However, the outlook is not uniform across the nation. While national forecasts suggest clear skies, local authorities in the south have issued warnings. A new cold front moving into Southern Brazil is expected to cause a change in weather patterns in Paraná [3].
Editorial staff at Bem Paraná said the arrival of this front should provoke storms in the region [3]. This creates a contradiction with broader national forecasts that predict a sunny weekend for all Brazilian regions [1].
Local authorities continue to monitor the movement of the cold front to determine the exact timing, and severity, of the predicted thunderstorms in the south [3].
“The majority of capitals should have temperatures above 30°C”
The divergence between national sunny forecasts and regional storm alerts in Paraná highlights the volatility of Brazil's current transitional weather patterns. While the 'veranico' brings heat to the majority of the country, the simultaneous movement of a cold front in the south indicates that the dry air mass is not yet absolute, maintaining a risk of severe weather in specific southern corridors.
