A shroud of cold air descends on the U.S.
From NOAA, an animation showing a wave of cold during the Martin Luther King Jr. holiday weekend last month:
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.
While you're at it, you might as well check out other videos on the NOAA Visualizations YouTube channel. Some good stuff.
Redrawn United States of electoral votes
Neil Freeman reimagined state boundary lines based on population. He started with an algorithm and the fifty largest cities, considered proximity, urban area, and commuting patterns, and then hand-tweaked boundary lines and shapes. The state names are mostly centered around geographic features (although I would have opted for ones based on dating profiles).
