What is the “polar vortex”?

The “polar vortex” is a circulation of very cold air which normally exists near the North Pole. Throughout winter, the vortex can weaken and pieces can break off. When a lobe of the polar vortex migrates south, it results in the coldest air of the entire winter.

That’s what happens Friday into Saturday.

A few reminders as the cold nears:

Limit time outdoors, consider adjusting plans Friday into Saturday
Check heating sources and water pipes to ensure they’ll be protected
Make sure humidifiers are good to go, this air will be very dry (dewpoints -30°)
Keep pets indoors. Consider making a contingency plan for outdoor livestock and farm animals
