ptb127 Posted February 21, 2011 Share Posted February 21, 2011 I thought this was just the OBS for storm 1. Not a forecasting thread. What totals map is this? Latest snow map drops the totals Link to comment Share on other sites More sharing options...
winterwarlock Posted February 21, 2011 Share Posted February 21, 2011 Latest snow map drops the totals interesting...I wonder why given their forecast totals call for much more everywhere. I happen to agree with this map over the bloated 3-5 inch calls Link to comment Share on other sites More sharing options...
NortheastPAWx Posted February 21, 2011 Share Posted February 21, 2011 I was asked why I don't think 7-10" will verify...precip amounts here don't support it (Barely 0.50" QPF for Luzerne county) and I've noticed these events kind of underperform here.

Ralph Wiggum Posted February 21, 2011 Share Posted February 21, 2011 21z srefs for rd 2 a little drier Yeah, but look how far North the spread reaches. At this close range, that seems like a fairly wide spread still to the North of the mean. Link to comment Share on other sites More sharing options...

It can't be just part 2 since the highest totals are in the Poconos. Link to comment Share on other sites More sharing options...

ChescoWx Posted February 21, 2011 Share Posted February 21, 2011 Actually snowing just west of Harrisburg now I think its worth noting at this juncture that its raining in the DelMarVa but not even snowing around Harrisburg yet. Link to comment Share on other sites More sharing options...
famartin Posted February 21, 2011 Share Posted February 21, 2011 What impact will that have? It seems as though precip upstream from most of the Del Valley is a lot of virga. The heavier band near HGR is gonna head toward Delaware. Link to comment Share on other sites More sharing options...
famartin Posted February 21, 2011 Share Posted February 21, 2011 Actually snowing just west of Harrisburg now York is reporting flurries (7 miles = flurries). Looking at radar reveals that the heavy stuff near HGR is gonna likely head ESE toward Delaware. Link to comment Share on other sites More sharing options...
