jacindc Posted January 23, 2016 Share Posted January 23, 2016 NWS lowered totals.. no clue why. Here on Capitol Hill I really haven't seen the rates that would support 24+. I had 11.5" (not on a board) at 4 am, and I doubt the rates will be there to get another foot here between now and when the storm ends. Link to comment Share on other sites More sharing options...
5speed6 Posted January 23, 2016 Share Posted January 23, 2016 What's the snow like for those of you in the whiteouts? Still light and powdery or is it heavy and wet now that it's coming off the bay? Fatter, wetter flakes in the last 10-15 minutes. We're being tickled by the dry slot here south of Annapolis. Link to comment Share on other sites More sharing options...

jon_snow Posted January 23, 2016 Share Posted January 23, 2016 back deck table has 15.5", 4:33AM. Kingstowne, VA. Like I said, my table might read a bit high since it's set slightly back in a row of townhouses. Link to comment Share on other sites More sharing options...
