The Beast from the East 2

According to the UK Meteorological Office:

"The 'Beast from the East' is a phrase used to describe cold and wintry conditions in the UK as a result of easterly winds from the near continent.

When pressure is high over Scandinavia, the UK tends to experience a polar continental air mass. 

When this happens in winter, cold air is drawn in from the Eurasian landmass, bringing the cold and wintry conditions that give rise to the 'Beast from the East' moniker."
