Esta é uma sondagem do GFS na próxima noite quando a chuva intensa deve estar começando na região de Angra dos Reis. Vento em 1km > 30 kt é bastante preocupante. Convecção profunda será favorecida por CAPE > 400 J/kg e cisalhamento de 30 kt.

🌩️This video explains the development of the tornadic storm near Porto Alegre on 31 March. The merger of two storms triggered the formation of a downburst. On the western edge of the downburst, a weak tornado then developed.

Storm-following loop of *the* supercell from last night that produced some incredible tornadoes in NE. Absolutely packed with interactions and mergers, the initial tornado looks to have begun after a newer updraft hit the inflow area of the original supercell and blew up. You

The flooding in Buenos Aires province, Argentina, occurred as a strong ridge and surface anticyclone settled east of southern Brazil and enabled continuous southward moisture transport. Precipitable water exceeded 3 standard deviations above normal along the stationary front

Very large hail in Rosario, Argentina, earlier today. Dry air near the surface, but an EML above 3 km that supports decent CAPE. Shear is not that strong, but this storm didn't seem to care

Timelapse of the life-cycle of the longest lasting tornado of the Arnett, OK LP supercell. This storm was spinning like crazy. #okwx

Multiple days of heavy rain fell on the state of Buenos Aires, Argentina starting last week.

The heavy rain in Vera, Santa Fe province, Argentina, was caused by an impressive backbuilding along a stationary front. The 850 hPa flow at 45 kt maintained convective development to the northwest of previous convection. CAPE and shear were both favorable for severe storms
