Original: polar vortex
Attention is turning to signs that the polar vortex is weakening, with meteorologists and local media discussing what that could mean for weather patterns across North America. A weakening vortex can disturb the jet stream, potentially allowing frigid Arctic air to spill southward into Canada and the United States. Forecasters caution the exact outcome remains uncertain, but cold snaps are a common result.
Why now: Signals that the polar vortex is weakening have prompted interest in whether harsh winter weather is imminent.
