NOAAVisualizations | A Shroud of Cold Air Descends on the U.S. @NOAAVisualizations | Uploaded 11 years ago | Updated 1 hour ago
A drop in the jet stream sent temperatures across the United States plummeting over the Martin Luther King Jr Holiday weekend. The pronounced change in temperatures can be seen in this weather data from NOAA/NCEP's Real-Time Mesoscale Analysis. Areas colored blue are below freezing. The diurnal cycle of heating and cooling can be seen over time, but the pattern is clear: much of the U.S. is pretty cold.
