Forecast
Snow for the Southwestern Alps with a Retour d’Est setup! But, to get straight to the point: don’t take the amounts in our forecast too literally this time, as they seem likely to be considerably lower.
Today, a front brings some fresh snow to the eastern Alps. After that, sunny high-pressure weather will return, but for how long? An upper-level disturbance (cold pool) is moving from Poland to Southeast Europe today.
Nothing new under the sun. Chris already mentioned in his Sunday weather report about the dominant high-pressure system, bringing plenty of sunshine and, so far, relatively low temperatures.
After an active week with multiple disturbances, we are now dealing with a prolonged high-pressure situation. The result is more and more sun and, in the long term, rising temperatures.
The last dump of this wet week is still ongoing in the Western Alps. Today, we look at what all the variability has brought and where the most powder has fallen. We also look ahead to the coming week, which will be dominated by a powerful high-pressure area.
From Sunday, we can expect stable high-pressure weather in much of Europe. Before that, we still have a few unsettled days ahead with rain and snow. Both the Southern and Northern Alps can still expect precipitation.
The Alps will remain in the warm sector of a depression near the British Isles today and Monday. The air is humid, and it is thawing up to an altitude of 1600 meters (Southern Alps) to 2300 meters (Western and Northern Alps).
The cold front that refreshed the base in the northern and western regions of the Alps has left, making way for dry and cold weather. However, this won’t last long as high clouds from the next disturbance will move into France this afternoon.
The days of strong high-pressure influence are coming to an end. The new year will start with a more unsettled period. This is being initiated by a cold front coming in from the northwest on Thursday.
For over a week, the Alps have been basking in the sun, but at the beginning of January, the weather map is really going to change. As is often the case with such transitions, it remains uncertain if and when the cold air will arrive.
