We've known that the USA is in for a bi-coastal blast of cold air, snow, and heavy rains, but this map by Jesse Farrell shows just how much of the contiguous USA has below freezing temperatures this morning.

Here is a summary of temperatures seen this morning by states:
  • All States except Florida (80% of US Land) are less than 32°F
  • 25 States (30% Land) Below 0 °F
  • 6 States Below -20°F

Of course, though not seen in the map above, Alaska has subfreezing temperatures, and Hawaii has subfreezing temperatures on the mountain peaks of Mauna Loa and Mauna Kea -not unusual for this time of year, but it is important not to exclude the 49th, and 50th states from any discussion about the USA.

Meanwhile, a once in a decade storm will hit California this weekend.
