Radar at 9:15 PM

Heavy snow continues to fall in the DC area and on the radar you can see, it's not going anywhere anytime soon.  The low pressure center in the midwest is transferring its energy to the low developing off the coast of North Carolina.  That will ride NE off the East Coast tomorrow.

A couple of power flickers here at Potential Vorticity central - so if I disappear from blogging, it's because of a power issue.

Oh and 7 inches at 9:30, which is an inch per half hour or two inches per hour of snowfall rate now.  You can see all the dark blue setting up over our area in the map below.
