Alert for heavy snowfall in Mendoza and northern Patagonia
As this Sunday progresses, it will begin to snow again in the mountainous area of Patagoniaespecially in the northern part of it, and on Monday there will be a significant intensification on the high mountains of Neuquén, also extending to Mendoza.
The mountainous area of Mendoza expects a large batch of snow in a few hours on Monday, with accumulations that can greatly exceed half a meter.. The entire region from northern Patagonia to southern Cuyo maintains a yellow level weather alert from the National Meteorological Service.
The situation will also be accompanied by strong winds in the mountain area, but fundamentally further north of the area where snowfall is expected, between San Juan and Catamarca.
Warmer weather, with precipitation in the center of the country and the coast
The first part of the week will be characterized by a slight rise in temperatures and especially humidity in the central and northeastern area of Argentina. Throughout Monday the north wind will be channeled strongly in the central provinces, leaving gusty conditions in San Luis, Córdoba, La Pampa and Buenos Aires.
Cloud cover will progressively increase in the center and north of the country between Monday and Tuesday, and for this day, the return of isolated rains and storms to northeastern Argentina is likely. During Wednesday, our ECMWF reference model predicts an intensification of these phenomena in the central part of the Coast, with probable strong storms and abundant rainfall, mainly over the province of Corrientes..
In the central provinces, a fairly overcast Wednesday with high humidity is expected, without ruling out some rains in Córdoba, the north of Buenos Aires and the Federal Capital.
Colder with snowfall, prior to the weekend with the May 25 holiday
The preview that we gave several days ago in Meteored Argentina about a new outbreak of cold in the country towards the May 25 holiday He seems to be gaining confidence.
Current projections indicate a new and widespread thermal decline in the country between Thursday the 23rd and Friday the 24th.sustained by the entry of relative high pressures associated with an intense south wind channel.
During Thursday, more rain and storms of varying intensity are expected in the center and north of the coast, while In the south and center of the country the south wind will accentuate the change in weather.
Precipitation will begin to become widespread as Thursday passes in central-western Argentina and, in combination with low temperatures, They could lead to snowfall not only in the Cuyo mountain range, but also in low areas of the center and south of Mendoza (such as the city of San Rafael) and low areas of the north of Neuquén..
Also, it is likely that towards the end of Thursday, precipitation in the form of rain will give way to snowfall in mountain areas of San Luis and Córdoba, according to our confidence model.
Between Friday the 24th and the holiday on Saturday the 25th, a new and notable thermal decline will be consolidated throughout Argentina.beginning a weekend that, like the current one, will have low temperatures as the main protagonists.
