Washington DC December Precipitation Update

As noted here at the time, the reported precipitation from National Airport in connection with the record-breaking December snowstorm appeared to be incomplete. The National Weather Service monthly climate summary for December 2009 is now showing a more realistic 1.34" for the 19th, as compared with 0.40" previously reported. This brings the corrected December total to 6.79", which would now be the second wettest December in history. The National Climatic Data Center statewide data (see previous post) show that December was the wettest on record in both Maryland and Virginia.
