high risk Posted Saturday at 05:21 PM Share Posted Saturday at 05:21 PM 4 minutes ago, BTRWx's Thanks Giving said: What is the maximum range for the NBM? You can't really define a range for it, as it is combining forecasts from multiple ensemble systems with some extra adjustments made with bias correction techniques for amounts (not spatial coverage). Ultimately, it only has much accuracy as the overall synoptic skill and skill-spread ratios of the various inputs, but its purpose is that it's not as prone to wild swings from individual solutions. That said, the "deterministic" solution shown in that previous post is worth looking at, but it should be done in conjunction with percentiles and probabilities. 4 4 Link to comment Share on other sites More sharing options...

Always wondered about how the ensembles factored into that. Much appreciated. 1 Link to comment Share on other sites More sharing options...
stormtracker Posted Saturday at 05:28 PM Author Share Posted Saturday at 05:28 PM ok, snow maps are coming out on the Euro and....looks like the GFS imo so far. it's at 84 with a little more left Amounts drop off north of montgomery county and B'more. Pretty map people do your thing. 2 Link to comment Share on other sites More sharing options...
SnowGolfBro Posted Saturday at 05:29 PM Share Posted Saturday at 05:29 PM This is starting to feel like January 6th. The northern crew is starting to pack it in (although I think there is more upside for you guys with this one). Jackpot zone from Quantico to Alexandria. With nice snows close to warning level up to Baltimore. I hope everyone scores big, but this is how it looks now. We don’t have the temps leading in to get a foot plus again, but 6-10 in the jackpot zone seems not unreasonable. Link to comment Share on other sites More sharing options...

NorthArlington101 Posted Saturday at 05:39 PM Share Posted Saturday at 05:39 PM So maybe I was harsh - there is the more solid push Tuesday then something that appears sorta separate… but it all kinda blends. This is probably a better map. 5 Link to comment Share on other sites More sharing options...

IronTy Posted Saturday at 05:40 PM Share Posted Saturday at 05:40 PM I'm torn, in order to make a late run to victory in the snow total comp I need these storms more north toward DCA/BWI. On the other hand I just want snow imby and this winter we seem to be in the bullseye so I can't complain. Link to comment Share on other sites More sharing options...
midatlanticweather Posted Saturday at 05:44 PM Share Posted Saturday at 05:44 PM Wow! Richmond and north to Fredericksburg look like the jackpot to me. I think it is a bit south, but not coming north anymore. Just hoping for precipitation expansion now 1 Link to comment Share on other sites More sharing options...

stormtracker Posted Saturday at 05:53 PM Author Share Posted Saturday at 05:53 PM I don't think anybody, plus or minus, should be locking anything in yet. There is still plenty of time for changes, especially with the models windshield wipe-ring every run. We we start getting into tomorrow, then models should start to converge I would think. 4 2 Link to comment Share on other sites More sharing options...

Yup if I recall the jan 6th event didn't get locked down till we were only 48 hours out. And even then it still drifted a bit north in the last 24 hours Link to comment Share on other sites More sharing options...

WVclimo Posted Saturday at 06:03 PM Share Posted Saturday at 06:03 PM Pretty rough run from the Euro up this way. GFS had the 3” line at the PA Turnpike. It never gets north of Montgomery County on the EC. Link to comment Share on other sites More sharing options...
