There is no chance they only got 0.7” new today. Just terrible measuring. I’m a few miles west of DCA as the crow flies and I got 3”. Matches up well with other reports in Arlington.
Very common there due to upslope. For the light events, sometimes there's no returns overhead but the winds out of the NW will cause light snow for days.
This morning reminds me of Deep Creek where it just doesn't want to stop snowing even if its light/non-accumulating like its been the last hour. What a morning.
Just measured over 3" of new snow. This storm easily gets a B+ in my books - longevity, winter scene, cold temps (i.e. no plain rain), and a snowpack with layers of ice to help keep it around hopefully.
