Weather tracker: temperatures plunge to -45C in parts of Russia

Siberian cold front forecast to push into China, Mongolia and then UK by Wednesday

A large area of high pressure covering the whole of eastern Europe is bringing severely low temperatures across Siberia. In a part of the world where temperatures are often below freezing at this time of year, the mercury has been 20C to 25C below average in areas over the weekend, with central and eastern Russia experiencing temperatures widely of -25C to -45C.

Over the next couple of days, westerly winds will result in temperatures rising above average in northern Russia but temperatures will remain 10C to 20C below normal in southern Russia. The orientation of the high-pressure system will allow northerly winds to send the cold air southwards across central and eastern Asia over the next few days. Temperatures will fall widely below average here too, with northern and eastern parts of China and Mongolia particularly affected. Temperatures here will fall 10C to 20C below normal by midweek as the same area of high pressure builds in and traps the cold air with temperatures struggling to rise above freezing by day.
