Polar Vortex 2024 Houston Time. Every winter, the polar vortex strengthens over the north pole. Observed and forecasted (noaa gefsv12) wind speed (top) and temperature (bottom) in the polar vortex compared to the natural range of variability (faint shading).

It’s a permanent feature that typically sits over the north pole, keeping the hemisphere’s coldest air in the polar region. Let’s see what noaa’s climate prediction center (cpc) predicts for the last month of winter.
