Polar Vortex February 2025

Polar Vortex February 2025. The polar vortex spins anticlockwise around the north pole with wind speeds of about 155mph (250km/h). Another key factor to consider is the strength of the stratospheric polar vortex (spv).

By next week, a third blast will hit the midwest and the eastern seaboard, plunging temperatures to subzero levels across at least 30 states. A strong/stable polar vortex usually means strong polar circulation and jet stream.
