Extratropical cyclone removing heat
An unusual cold at the end of December caused isolated frost formation in the lowlands of Planalto Sul Catarinense and the São José dos Ocentes region, in the Campos de Cima da Serra.
But what is the reason for the low temperatures in southern Brazil? According to MetSul, an extratropical cyclone off the coast of Rio Grande do Sul has pushed cold air into the area, resulting in cool nights and pleasant afternoons this time of year.
For those who like cold bad news. The low temperatures did not last long and the heat returned. For this Thursday (28), for example, thermometers will exceed the 30°C mark in Porto Alegre. After all, it's summer.
