Current situation and outlook
High Erich has us firmly in his grip. Since the last PowderAlert in the east, and for several weeks in the west, the sun has been shining almost uninterrupted. There is thick fog in the lowlands, but above it is again (or still) relatively mild and bright blue. Erich is a kind of side arm of the more or less stationary Azores High, which naturally tends to lie over the Azores, but also repeatedly stretches towards Europe.
The polar vortex currently has its main center between Greenland and northeastern Canada. There is repeated development of low pressure from eastern Canada over the east coast of the USA, which leads to warmer air being transported from south to north over the Atlantic, which in turn strengthens the Azores High. The cold air over Scandinavia and north-western Siberia is fighting against high pressure on the other side of the world in the Kazakhstan/SW Russia region. Between the high pressure in the eastern Atlantic and Central Europe and the high pressure in Central Asia, there are repeated outbreaks of cold air to the south - most recently during the last snowfall event in the eastern Eastern Alps.
