Between the end of Thursday night and the early hours of Friday, the Uruguayan Institute of Meteorology (Inumet) forecasts rapid drops in temperature that will accompany a cold front. According to meteorologist José Serra, summer “is saying goodbye today (for this Thursday) practically, depending on the temperatures.” “It’s the last hot day we’re going to have of the summer,” added in dialogue with The Observer.
Inumet’s Twitter account reads: “We anticipate that between the end of the night of today Thursday the 17th and the early hours of Friday the 18th, enter through the south of Uruguay a cold front. This situation will favor deteriorates, lowering the temperature with the rotation and increase of the wind southeast and south direction“.

In the same tweet, Inumet attached a video explaining what is a cold front and points causing “rapid drops in temperatures”.
“It occurs when a mass of cold air advances towards lower latitudes and its leading edge is inserted like a wedge between the ground and the warm air. During its trajectory, the mass of air that has been displacing the warmer air causes rapid drops in temperatures in the region through which it passes“, explains the audiovisual material.
José Serra’s prognosis goes in the same direction. “Starting tonight, the cloudiness will begin to increase”this “due to the advance of a cold front of rapid displacement that will affect much of the national territory. The meteorologist predicts that “some precipitation” between 5 and 15 mm, and does not rule out “the punctual formation of some storm cell“, where there are likely to be “higher precipitation volumes”.
“This situation will lead to a marked drop in temperatures he claimed.
On Fridayaccording Serra, “they are going to be between an average maximum of 20°, 21° and a minimum of 16th, 17th“. Both Inumet and AccuWeather agree on the overall forecast for Serra, but point possible storms for this day.
Already the next day, Saturday, “starts to get better”though “will persist some instability in the north and northeast of the country with some rainfallimproving rapidly by midday.” Temperatures “will hover around 20°, 21° degrees the maximum and a minimum of 15° to 16° degrees,” said the meteorologist.
The Sunday will be found “again stable with somewhat cloudy to cloudy skiesand temperatures of 22° to 23° maximum, and 15°” of minimal. Although during the campaign “they will be able to reach 9th, 10th“, he indicated. That same Sunday the 20th, at “approximately 12:56” autumn begins, he told The Observer.
For Monday, Serra estimates that the temperatures “will remain autumnal”, despite the fact that in the first days of the season there may be “some slight pulse of heat, where temperatures they can reach 25°, 28° again.” “It is feasible, it does not mean that it will happen,” he clarified.
“The trend for fall is normal or slightly below normal rainfall in the southern region, and slightly higher in the northeastern region of the country,” said the meteorologist.
