Polar Vortex 2024 Usa Time. Winter 2024/2025 is about to begin (meteorologically) in a very dynamic way. The majority of the forecast models say yes, the winds at 60 degrees north* (the mean location of the polar vortex) will briefly reverse direction within the next week or so, commencing the second major sudden.

Following a polar vortex disruption in early march, winds at 60 degrees north (outlined in magenta) on march 16, 2024, were mostly from the east—a reversal of the normal. Meteorologists believe that polar vortex disruption a couple of weeks ago in the lower levels of the stratosphere could help energize a stronger disturbance higher up.
