The focus of the weather forecast remains on the intense heat wave in central Brazil. This phenomenon has caused temperatures to be close to or above 40°C in several parts of the country's central and southeastern regions. Especially in the Midwest, the situation is very dire, as part of the soybean soybean crop is in the flowering stage.
Higher temperatures and lower humidity are expected to impair the productive potential of crops. Although the weather is dry in most parts of the country, localized heavy rains are expected in the southernmost and western parts of the northern region. In addition to the extreme irregularity of precipitation, this is true even in small areas.
Northland: Increased rainfall in the Amazon, but Tocantins remains dry
Tropical instability in the region is expected to remain active and intensify in the Amazon. **Shows rainfall between 25 and 40 mm, punctual and isolated. In the eastern part of the region, such as Tocantins, the weather is dry due to the strong hot and dry air over central Brazil.
Northeast China: Dry weather with irregular rainfall
The predominant weather in the region is hot and dry air masses. However, temperatures are expected to be lower in most parts of the northeast than in the central part of the country. In addition, humid winds from the sea will favor some instability in the eastern part of the region, with the highest winds expected in the Sealba region. In the state of Maranhão, tropical instability brings localized rainfall, with rainfall variing between 3 and 7 mm, indicating a large irregularity in precipitation.
Midwest: Soybeans in the Midwest are experiencing high temperatures and droughts
The center of the hot and dry air mass is located in the central region of the country, bringing extreme temperature conditions and low humidity. As a result, temperatures should be close to 40 in almost all areas of the Midwest, with the exception of the South and Northwest. These high temperatures will be accompanied by a relative air humidity of about 20% or less, increasing the plantation's water requirement and increasing the stress caused by the high temperatures. Some soybean plantations are in the flowering period, which is a critical period that determines crop yields. Unfortunately, the combination of high temperatures and low humidity hinders the growth of this crop today.
Southeast: Temperatures above 40°C in the northwestern part of São Paulo and in the Minas Gerais Triangle
Temperatures are expected to remain extreme in the region, especially northwest of Paulista and the Mineiro Triangle. The thermometer must exceed 38°C and approach 40°C. These high temperatures are inevitably accompanied by low humidity, which, in addition to exacerbating heat stress, increases the water requirement of crops. **Indicates that there may be some scattered and punctual rainfall in the west of São Paulo, but less than 3 mm of rainfall. In other areas, the weather should be predominantly sunny.
Southern Region: Thunderstorms in the south, increasing high temperatures.
The cold front is expected to act on Uruguay, causing heavy rainfall in neighboring countries and possibly crossing the southern border of the state of Rio Grande do Sul. There is a high probability of storms associated with this system, mainly due to the heat wave that is taking action against Brazil. In addition, temperatures are likely to rise in the south. This happens both due to heat waves and to the situation of the "prefrontal lobe", where hot air accumulates at the forefront of rainfall. Thermometers in the metropolitan area of Porto Alegre, northwestern gaucho, western and southern Santa Catarina, and northern Paraná can exceed 35 ° C.
