Northeast warms as big freeze sweeps southward

Historic lows forecast for many regions; cold wave expected to begin exit on Tuesday

As extreme cold weather continues to move southward across China, bringing the lowest temperatures recorded in decades, northeastern parts of the country have already experienced some localized warming, the National Meteorological Center said on Sunday.

Temperatures rose by up to 10 degrees in some regions on Saturday, yet China's national observatory continued to renew its orange alert for the cold wave moving south.
