Earlier this weak, the meandering jet stream brought Arctic air, ice, and snow down to South Texas. Now it’s bringing heat and dust from the Sahara all the way to central Europe.

A #winterstorm2021 down to South #Texas?
Usually a strong polar vortex confines Arctic air to the north. It's stabilized by a high temp. gradient between low & high latitudes. The lower the gradient, the more the wind belts meander, transporting cold air south/warm air north.
