Clear sky over the Alps, snow red colored.
At Zurich Airport (LSZH), cold fog is dissipating, coinciding with the approach of a United States Air Force aircraft.
Over Italy, dense high-altitude cloud cover, with the presence of Saharan dust exhibiting typical rippled cloud-tops.

Low stratus blankets the northern Alps today, pushing into pre-Alpine valleys with a ceiling of ~800m (Rigi webcam); valley shape+exposure matter more than the fog’s height.
Alpine valleys have foehn with up to 14°C, the southern Alps have thick cloud (but little rain), spilling over the main ridge

Let's check in a see which year since 1940 was the warmest and which one was the coldest for all of the Earth. Red colors are closest to 2025, and blue colors are closest to 1940. I spot a slight difference.

Central Europe has finally received fresh snow.
With arctic air mass and clear skies widespread severe chill are expected Sunday night, with some Alpine valleys reaching −30°C!
The cold wave persists until Thursday, after which stormy westerly winds will introduce again milder atlantic air.

Vielleicht schaffen wir es zumindest, Waldbrände nicht nur auf Brandstiftung zurückzuführen. 12jährige, die Feuerwerkskörper zünden, gab es immer schon. Extreme Trockenheit, die daraus Waldbrände macht, ist hingegen eher neu. Guter Journalismus würde das einordnen. www.derstandard.at/story/300000...

Under high pressure, the Alps will experience dry, often sunny and clear weather. In the north and southeast, persistent low stratus cloud may linger over low-lying areas.
Snow cover (shown in blue) is more extensive than usual for this time of year.
