He southern Chileespecially the southern areacontinues under the effects of an atmospheric river of category 2, which keeps active intense rainfall with high zero isotherm. Although the rest of the country is expected to be warm and stable, the front associated with this atmospheric phenomenon will continue to cause persistent rains in specific sectors of Patagonia.
According to the Meteorological models more recent, until Thursday 28 could accumulate between 60 and 120 millimeters additional rain in sectors of the Aysén region and the South Cordillera de los Lagos. This frontal system remains almost stationary due to a strong anticyclone over the central area of the country, which prevents its displacement towards the south, concentrating rainfall in that area.
Nevertheless, This anticyclone is expected to start weakening from Wednesday, allowing the front to advance slightly north. This will coincide with the arrival of colder air in height, which will cause the zero isotherm to begin to descend and that rainfall migrate to new areas.
Possible snowfalls and rains in the country’s center-south
He European medium -term forecast center (ECMWF) He anticipates that the last strong rainy wave in Patagonia will occur on Wednesday 27. As the frontal system tilt to the north, driven by cold air at its back, low surface pressure will be developed that will be combined with a cold core in height. This will generate weak and scattered rains in the central and south zone during the second half of the week. In addition, this low pressure is expected to destabilize the atmosphere, causing intense drizzles in Valle, coast and the Cordillera de la Costa sectors. In contrast, some areas of the mountain range between Valparaíso and Biobío could receive snow showers, highlighting the contrast with the warm and sunny days that are experienced at the beginning of the week.
Variable climate towards the weekend
During the weekend, the ECMWF model projects that this low pressure and a more pronounced trough They will remain over the center of the country. This could give way to isolated thunderstorms in center-northern mountain sectors on Saturday. In the southern area, meanwhile, an improvement of conditions is expected, with stable time and upward temperatures due to the warm upset prior to the entry of a new front system.
Northern Chile: Heat and some coastal drizzles
In nOrt of the countrythe clear skies Inside, with temperatures that will exceed 30? ° C in locations such as Pica, Huara and María Elena. However, a slight thermal descent is anticipated towards Friday due to the entry of colder air in height. In coastal sectors of Antofagasta, Atacama and even in Iquique, morning drizzles could be recorded between Friday and Saturday, the product of a height trough that will run from the south.
