What Happens When Western Europe Meets a Siberian Freeze

Sub-zero weather from Siberia is covering western Europe, and forecasts say it may stay a while.

Europe is gripped by some of the coldest weather in a decade, blanketing the continent in snow and sub-zero temperatures from Dublin to Dubrovnik.

The later winter freeze has roiled energy markets -- forcing utilities to scramble for natural gas to heat millions of homes -- and disrupted travel across the region, blocking roads and closing airports.

On Thursday, British weather forecasters issued a red weather warning, signaling life-threatening conditions, for Scotland and southwest England as new band of snow swept northward across the country. 

Some of the severest weather has been in the Baltic states, where temperatures dropped to as low as minus 29 degree Celsius (minus 20 Fahrenheit) in Estonia earlier this week.

The unseasonably cold weather, caused by a steady flow of icy, Arctic air from Siberia, could last for another two weeks, according to forecasters at Accuweather, delaying the start of spring.
