At the same time, severe bora winds are affecting Croatian coast and Montenegro.

With an extremely cold airmass advecting over relatively warm seas, convective lines are maintaining going ashore and producing intense snowfall combined with orographic features and a so-called "stau" effect excessive snowfall, Severe Weather Europe experts explained.

Locally strong winds are pushing real feel below - 20 °C (-4 °F) in these areas while eastern Poland, northern Ukraine, and Belarus are experiencing -25 °C (-13 °F) to -35 °C (- 31 °F) windchills, towards -50 °C (-58 °F) in Russia.

A deep cyclone is centered over the Aegean sea, maintaining still mild temperatures over the southern Greece and Turkey - this will significantly cool through until the evening, the Severe Weather Europe said.
