Meteorologist explains weather forecast for the last week of July, in Paraná The passage of a cold front and the formation of an extratropical cyclone should mark the meteorology this last week of July in Southern Brazil, according to Climatempo. ? Follow the g1 PR channel on WhatsApp The most affected state should be Rio Grande do Sul, which is under warning of strong storms. In Paraná, most of the week should have stable weather, according to the Environmental Technology and Monitoring System (Simepar), but rain is forecast in the middle of the week — when the territory of Paraná may also experience storms. On Tuesday (28), in the southern half, winds can reach 50 km/h and rains are expected to start during the night; on Wednesday (29), they spread throughout the state, says Simepar. "Throughout the last week of July and the beginning of August, several meteorological situations will act together to cause a lot of rain in the south of Brazil: low atmospheric pressure, passage of an oceanic cold front, formation of a cold front in the interior of the continent, formation of an extratropical cyclone, tendency for cyclonic circulation of winds around 5 km in altitude and a hot and humid wind current coming from the Amazon (low-level jet)", adds Climatempo.

This Monday (27), there is no rain forecast and maximum temperatures could approach 30ºC in the west and north regions. See the forecast by region below. On Tuesday (28), the weather changes little during the day. The sun continues to predominate and temperatures remain high. However, wind gusts are expected to be strong due to the intensification of a low pressure system between Paraguay, northern Argentina and southern Brazil. "By the end of the night, rain can already reach areas in the west, southwest and center-south of Paraná. On Wednesday (29), the rain advances over Paraná and spreads throughout the day. Conditions are favorable for rain showers accompanied by lightning and localized gusts of wind", says Simepar. On Thursday (30) the instability loses strength. The sky remains very cloudy in the east and there is the possibility of very occasional rain. On Friday (31) the weather becomes stable again. Cloudiness still predominates in the center-south, Campos Gerais, southeast and east of Paraná, while in other regions the sun appears more frequently. As a result, temperatures rise again, with maximums close to 30°C between the west and north of the state and around 24°C in the other regions of Paraná. ??Forecast by region See, below, the weather forecast updated by Simepar this Monday (27): Monday, July 27th Monday, July 27th Reproduction/Simepar Tuesday, July 28th Tuesday, July 28th Reproduction/Simepar Wednesday, July 29th Wednesday, July 29th Reproduction/Simepar Thursday, July 30th July Thursday, July 30th Reproduction/Simepar Friday, July 31st Friday, July 31st Reproduction/Simepar Most watched videos on g1 Paraná: A 23-year-old man was indicted by the Civil Police of Paraná for using artificial intelligence (AI) tools to make pornographic montages of a 21-year-old girl who ignored him on social media and publishing them on an adult content website o Read more news on g1 Paraná
