The conventional and A.I. powered models all showed a strong Arctic blast with a lobe of the lower-stratospheric / upper-tropospheric polar vortex slowly but surely rotating through the Lower 48.  The extreme cold is outperforming forecast guidance from several days ago most likely because of snow cover and underestimating the strength of the cold airmass up in Alberta.  I\u2019m particularly impressed with the wind chills into the minus 30s and minus 40s into Iowa, Indiana, and Illinois including Chicago.  There is a huge population under this frigid cold dome.</p><p>Temperatures at 6 pm ET were colder than -10\u00b0F in Iowa and -6\u00b0F in Chicago with subzero temperatures bending around Lake Michigan into southern Michigan.</p>",
