KagiAI summary:

A Sudden Stratospheric Warming event (SSW) is forecast to displace the Polar Vortex and potentially shake the weather patterns in the coming weeks. The Polar Vortex behaves like a very large cyclone, covering the whole north pole down to the mid-latitudes. Rossby Waves (a pair of strong high and low-pressure systems) deflect energy upwards into the Stratosphere as they break, temporarily pausing its strengthening or weakening its circulation. The influx of energy into the Stratosphere creates a major disruption and warming, completely collapsing the upper stratospheric Polar Vortex. The forecast for the 30mb pressure level in the Stratosphere shows a complete collapse of the upper and middle Polar Vortex. The pressure pattern analysis for the weekend shows a strong lower core of the Polar Vortex bringing very cold air over the Midwest and the eastern United States. The temperature anomaly also shows the strong, abnormally high temperatures surrounding the Vortex, weakening it further. The expected pressure pattern post-SSW is high pressure over the polar regions and low pressure in the lower latitudes, prompting a low-pressure response over the eastern United States and Europe. The temperature anomaly from the CFS ensembles shows this cold extension from Canada down over the Midwest and into the eastern United States. An interesting fact is that the Polar Vortex can reach over 50km/31miles in altitude, making it a powerful force in the atmosphere.
