Wow!  What area of Germantown are you?  I am next to Milestone near 355 and 27, and have closer to 6 inches.

Just went around the corner to pick up a pizza and the roads are BAD again.  Moderate snow and 29.

East of Daly Elementary.

 

I bet the roads are terrible right now. I have 6" on hard surfaces but there is a ton of compaction on them. 9" on anything that is insulated.

Finally getting the Loudon-Fairfax-DC-MoCo superband!  Big flakes and best rates of the storm.  Picked up around 520pm while I was shoveling/snowblowing.  Driveway covered again.

 

Measured 0.2" on the snowboard at 5pm for a storm total of 6.1".  I'm sure there's more than another 0.2" already in the last 20 minutes.

Thanks for getting schools closed. ;)

This storm broke a lot of mid atlantic rules of thumb

  • Onset earlier than forecast
  • Virga was minimal
  • Models kept get better through and after onset
  • Snowfall was unusually evenly distributed
  • There was no parrs deathband (i feel bad for psu)
  • Nova and DCA are jackpotting 
  • Warm air advection overperformed
  • Upper level low qpf is higher than forecast
  • Shutoff is later than forecast
  • Start to finish will span 30 hours

Let all that sink in for a minute...
