The polar vortex is at it again.
The weather phenomenon responsible for bone-chilling cold fronts settling over parts of North America and Europe, including those that normally experience mild winters, has held much of the central United States in its icy grip the past few weeks.
In mid-February, a blob of Arctic air moved as far south as Texas, causing extreme cold and heavy snowfalls, loss of life, traffic chaos and power outages for millions. According to the US National Weather Service, more than 100 million people over a distance of 1.6 million square kilometers were under winter storm warnings.

Accurate advanced warnings can save lives. A study from the University of Washington and the National Oceanic and Atmospheric Administration describes a new way to rate and possibly improve tornado warnings. It finds that nighttime twisters, summer tornadoes and smaller events remain the biggest challenges for the forecasting community.
