WEATHER UNTIL NOVEMBER 19, 2024, ANALYSIS AND FORECAST
Instability continues to dominate the weather scene on the Major Islands and part of the South, but the new element is related to the worsening in the North-West regions, due to a cold impulse moving from France towards Spain.
This colder air flows along the eastern flank of the anticyclone that places its maximum over the British Isles. In some way, the Mediterranean remains exposed, thus reinvigorating the depressionary circulation already present at low latitudes, with worsening also in the peninsular areas of the southern regions.
Part of the cold flowing west of Italy is responsible for the more noticeable temperature drop in the North, which is favoring snowfalls in the Western Alps from 1000 meters. New cold air will be drawn from the Balkans towards the Adriatic regions during the middle of the week, thus fueling instability both in the South and along the southern regions. There will be a further temperature drop.
Meanwhile, the weather will improve in the North-West, due to the cold vortex currently over France moving away towards Spain. The isolated cyclonic circulation over Spain will remain a threat, as it will be hooked by a new Arctic plunge descending from Scandinavia over the weekend.
Pending confirmation, a new worsening of the weather is likely starting from Sunday 18 in the most western regions, but with more evident effects at the beginning of next week.
