Extreme heat wave: Argentina will be the hottest place in the world

RIO DE JANEIRO, BRAZIL – After the brief respite, a new heatwave is on the horizon for the middle of next week in much of Argentina. It should be even more intense than the last one, with a regional atmospheric circulation configuration that is quite atypical and reminiscent of the most extreme heat situations it has experienced in recent years.

The country is in for a hot weekend. The heat will increase mainly in the Pampas, and northern Patagonia, where the most unusual values compared to the averages are expected on Saturday and Sunday, with values ranging from 37 to 41°C.

In the rest of the center and the north of the country, maximum temperatures will continue to be around 35°C, especially in Buenos Aires and in the various areas of the Atlantic coast, where temperatures will hardly exceed 30°C due to the persistent easterly winds already mentioned.

As for precipitation, there is little or nothing to report in the country in the short term. Scattered showers are likely Saturday over southern Patagonia, which is much cooler and windier than the rest of the country.

In northern Patagonia and southern Mendoza, favored by the high heat, showers and thunderstorms are expected starting Saturday afternoon. They could be repeated in the north of Argentina, especially over Misiones and some mountainous regions of Salta and Jujuy.

On Sunday, showers and thunderstorms could return over Misiones in eastern Formosa. North of Corrientes, west of Mendoza and San Juan, and in the mountainous regions of the northwest.

NEXT WEEK, ON THE BACK BURNER

Next week, a block-like atmospheric circulation pattern will emerge, a very rare but likely constellation to be found under a La Niña event like the current one at this time of year, providing ideal conditions for the most intense heatwaves in Argentina.

Under this scenario, southern South America, particularly Argentina, will most likely become the hottest place on Earth starting next Tuesday, with temperatures exceeding 40°C in much of the country, according to forecasts from various meteorological models.

The heatwave will extend until at least Thursday, June 13, with maximum temperatures in central provinces such as Buenos Aires, Córdoba, Santa Fe, and Entre Rios ranging from 10°C to 15°C above normal.
