The National Oceanic and Atmospheric Administration has released a map depicting the ongoing record-setting blast of arctic air in stunning detail.
Using data from its High Resolution Rapid Refresh (HRRR) model, NOAA released a map showing expected low temperatures across the Lower 48 for the night of Nov. 13-14. Below-freezing temperatures are depicted as far south as the Gulf Coast states. The HRRR model, in development for five years, finally became "operational" -- in other words, ready for everyday use in real-time weather forecasting -- in September.
The slideshow above starts with NOAA's map. But we couldn't stop there. Using our own high-resolution temperature data, we take you closer to the polar plunge with 11 more maps showing how the bitterly cold air charged across the Canadian border and sent temperatures crashing across a huge swath of the country. Click through the slideshow above for a closer look.
