Atlantic low-pressure areas have now transported more cloudy sea air to our western region, causing endless humidity. Pike soaked snow brought 50 liters per square meter in one day.

Hoch Reiner completed the late winter spectacle. Together with the adversaries, the southern current developed, with which the warmer and drier weather reached our region. After that, the temperature went in the opposite direction again.

It was also affected by Easter under the influence of Hoch Spiro over Scandinavia, which remained friendly and dry but fresh due to the continental air flowing with the east current. At night, the mercury even fell into the mild cold range.
