Temperatures have climbed above 31 C (88 F) degrees everyday since Dec. 13 in Buenos Aires.

This long-duration heat wave has put stress on the electrical grid of Argentina resulting in blackouts that have left many without power and any way to cool down.

At long last, relief is on the way in the form of a cold front that crossed the region Wednesday night, bringing both cooler air and lower dew points along with drenching rain.

Prior to the front, temperatures climbed to around 34 C (93 F) on Wednesday.

As the front crossed the the region early Thursday morning, heavy rain fell in many places. Buenos Aires had received over 6 cm (2.3 inches) through Thursday morning. Farther north, nearly 9 cm (3.43 inches) of rain drenched Rocha, Uruguay.

Temperatures will remain seasonably warm on Thursday; however, dew points will lower by day's end and reduce the impacts of the heat.

By Friday, both lower dew points and temperatures will be found across northern Argentina, including Buenos Aires.

Temperatures will begin to climb over the weekend and into early next week. Highs in the mid-30s C are expected by Monday. Another cold front may work back into the region later Tuesday and could bring a bit of relief, but temperatures should stay at or above normal through the end of the week.
