Once in a Blue Moon

As another snowy December came to a close, the lunar cycle displayed it's second full moon of the month. For the first time in almost 20 years, there was a "Blue Moon" on New Year's Eve. While 2010 begins, forecasts call for a dry and temperate pattern to evolve for the region, we'll see. (OSNW3 January Observations)

(December 2009 Radar Loop)
About a week ago WxWatcher inquired about radar loops to share in his classroom. There are a few good ones that currently exist on the OSNW3 website, however I felt it necessary to loop the entire month of December as it became one to remember around the nation. Plenty of good storms to analyze and remember. Choose a link below and enjoy!
