Follow the g1 Ponta Grossa and region channel on WhatsApp Meteorologist Bianca de Angelo explains that the week began with the formation of a new low pressure area close to the coast of Argentina, which favors atmospheric instability in some regions this Monday (6). According to her, in the southern half of the state, rain occurs persistently throughout the day, with accumulations varying from light to moderate, and in the northern half there is the possibility of isolated rains, with higher temperatures. "In the north, the maximum exceeds 22°C, reaching approximately 26°C in municipalities such as Colorado, Sertaneja and Loanda. In the Center-South, in the metropolitan region of Curitiba and on the coast, the weather remains cloudy, keeping temperatures varying between 17ºC and 20ºC. The lowest maximums are predicted in the southwest and west of the State, with temperatures between 13ºC and 16ºC", he says. Frost: What is it and what conditions are necessary for the formation of the phenomenon? On Tuesday (7) the low pressure area moves towards the ocean, losing its influence over the state. There is still light rain forecast between the northern half of the state and the coast, but the main highlight is the arrival of cold air masses. "During dawn, only the west and southwest region record temperatures below 10°C, while in other areas the values ??are milder. However, throughout the day, the polar air mass advances over the state, causing a sharp decline in temperatures", he points out. In the early hours of Wednesday (8), negative temperatures are forecast in the vicinity of Palmas, in the south of the state, with favorable rates for the formation of moderate intensity frost between Palmas and União da Vitória. Cities in the central region, Campos Gerais and west of Curitiba may also record the phenomenon, at a weaker intensity. See the map below. Throughout the day, the predominance of the Sun favors the rise in temperatures in the afternoon and the maximum temperatures once again exceed 16ºC in all regions of Paraná, says the meteorologist. Frost forecast for Wednesday (8) Reproduction/Simepar In the early hours of Thursday (9), explains Simepar, temperatures drop again - however, there are no longer forecasts of negative values. During the afternoon the highlight becomes the northwest of the state, where the action of a hot air mass once again favors highs above 27°C in municipalities such as Icaraíma and Umuarama. "On Friday (10) a new area of ??instability causes the return of rain in a timely manner in the west of Paraná. Temperatures maintain the typical pattern: cold mornings and afternoons with rising temperatures. In the northwest, maximums exceed 30°C", concludes Bianca.
