Ian Posted December 13, 2010 Share Posted December 13, 2010 I have been playing around with dalies and combined daily info that is part of my 'snowstorm database' to pull some La Nina specific info at D.C. Still a work in progress, but will post some now and keep adding. I will use the following two posts for updates in the future so they will remain at the top of the thread. I will also note when I make additional entries by making a new post at the end of the thread with the change. zwyts provided the following list of Ninas back into the early 1900s. If anyone has issues with this list plz don't be afraid to note them. I would like to have accurate info where possible.

Ian Posted January 25, 2011 Author Share Posted January 25, 2011 Mod/Strong Nina Years - 14 in Total i noted on 12/16 that the first snow came in that big cluster--now we have a fairly legit if not settled threat right near the "peak" of the graph. obviously the sample set is way too small but eh.
