That makes me think we do real well as I don't remember any storms where they get smoked that we didn't get hammered unless the storm slid way to our south and east. 

That's exactly what I was wondering all yesterday. What other Miller A has ever gone from dropping 7-11" of snow in Charlotte, then come up the coast on a classic track with plenty of moisture, and yet flips over to plain rain for a significant chunk of the storm for the entire DC to Boston corridor (what the warmer models were showing yesterday)?

Negative tilt troughs can screw new england,  we've had some big snows where they've rained in Boston.  Not common but the blizzard of 66 was such a storm.

1/22/87, 1/25/00 and 12/29/00 weren't that kind to Boston either... but, yeah, that does happen with a city or two. It was just this idea that everyone from here through Boston was going to be receiving less snow than Charlotte and now perhaps Raleigh that was intriguing...

if you go to trafficland.com and go down to VA... You can clearly see where the snow is based on the traffic colors of the roads. Red/Black in NC, yellows showing up in Blacksburg/Roanoke, green in Lynchburg.

 

Thanks for the reminder. I forgot to post my usual link.

Navy Yard runs cold but according to the weatherbug station, they made it to 26 today ( add a degree or two to that for actual temp since they run cold) --- now down to 24 degrees... the forecast high was 30, and then was adjusted up to 33, but we never came close.

 

Definitely going to be cold for the front end thump.
