Overview
- SMN forecasters, in updates Friday, said rain and thunderstorms will develop Saturday, May 16 in many Argentine provinces, with some northern areas holding showers into Sunday and a sharp drop in temperatures to follow.
- Forecasts call for 50–70 km/h winds with higher gusts in Patagonia and the central belt as the cold air drives frost risk and possible mountain snow at high elevations.
- In the Buenos Aires metro, isolated showers are most likely Saturday, then a colder and drier Sunday with early lows near 6–7°C.
- Conagua expects very hot conditions in parts of Nuevo León, with 40–45°C possible in specific municipalities and only spotty rain in the state.
- Across the Yucatán Peninsula, a low-pressure trough and tropical moisture will bring scattered showers with very hot daytime conditions and fresh coastal breezes, reflecting the seasonal split of polar air in southern South America and a heat‑building high over Mexico.
