How long will the extreme cold temperatures last, and what changes are expected in the coming days?

The extreme cold temperatures affecting regions like Wichita, Kansas City, and Oklahoma City are showing signs of change in the next 6-10 days. According to the Climate Prediction Center, temperatures will return to normal along the East Coast, with areas from the Dakotas down to Texas expected to be above normal. This marks a significant shift from current conditions where temperatures are running as much as 40 degrees below normal, potentially breaking records for cold highs. Meanwhile, Miami is predicted to cool down slightly. This warming trend indicates the polar vortex's grip will loosen, bringing relief to the millions currently affected by the unusual winter weather.
