7 inches is about right. Add this to the 24-27 inches received on the February 6-7 storm and close to a yard of snow is now on the ground.

As if this were not enough, the Washington region set a hundred year for snowfall this season today according to The Washington Post.

Reagan National Airport (DCA) reported 1″ of snow between 1 and 2 p.m., upping its storm total to 9.8″. It has received 54.9″ this year, exceeding the 54.4″ of 1898-1899.

Some local snowfall measurements, some unofficial courtesy of the National Weather Service. Note the official 32.4 measured at Washington Dulles below. Herndon readings suggest 24-26 inches of snow, or about five inches more than we received in the December 19-20 storm.

This snowfall appears to be a record breaker, and bigger than the storm of February 1979.

With all the snow and drifting snow it is hard to get an accurate measurement of snowfall. Here are some snowfall measurements at suggest that Oak Hill has had about 15 inches of snow as of early this morning. Most likely we are closer to twenty inches at this point. This storm will probably break all records. The storm is supposed to last until around ten p.m. tonight.
