After several days with temperatures above average for the time of year, showers, thunderstorms and hail will return. Therefore, a sudden change in weather is expected that will make mainland Portugal “return to winter”.
According to Alfredo Graça, geographer and specialist at the meteorological information project Meteored, this change occurs with the arrival of a cold depression coming from Greenland. “This isolated cold depression, associated with a maritime polar air mass, will soon form south of Greenland and travel rapidly across the Atlantic until reaching mainland Portugal next Friday, April 26,” he says.
“Before that, tomorrow (Thursday) the first signs of the imminent change in the weather will be felt: a first front associated with this depression will leave periods of rain in areas of the North and Center on Thursday afternoon (25) , not to mention the drop in temperatures”, he continues.
The cold depression will bring rain with greater intensity and abundance in the afternoon and evening and, above all, in the regions located west of the Condensation Barrier (districts of Viana do Castelo, Braga, Porto, Aveiro and western areas of the districts of Vila Real and Viseu). Snow is also expected in the highest points of Serra da Estrela and, at the end of the day, in points in the extreme north above 1200 meters of altitude.
For the early hours and morning of Saturday (27), a meteorological situation of rain is expected to continue, worsened by a further drop in temperatures, which will result in snowfall until mid-morning in the mountainous areas of the North and Center above 1200 meters altitude. There will be a risk of thunderstorms and the possibility of hail in some parts of the country cannot be excluded.
For Sunday (28) a temporary worsening of weather conditions is expected, but in the afternoon a new occurrence of precipitation and snowfall is expected.
