This new NCDC data covers the climatological period from 1980-2012 instead of 1960-1990, so this is a big update. Last year I talked about some of the changes, and showed a comparison of the old and new maps, and changes in individual cities. This year, we're going to start our "2012 White Christmas" forecast maps later this week -- meanwhile we have an article about this graphic and why some areas are more prone to a white Christmas than others.

The extreme rain continues today, with the Carolinas in the cross-hairs. This one could be a 1,000 year event.
Hurricane Joaquin rapidly strengthened into a monster storm overnight -- this changes everything.
Will Hurricane Joaquin be the next "Isabel" or "Sandy?" Does it even matter?
