TauntonBlizzard2013 Posted December 15, 2019 Share Posted December 15, 2019 The one common theme in this is no matter where the heaviest axis of snow is... the amount really aren’t all that impressive. I think we are talking like 5” where the best stuff ends up Link to comment Share on other sites More sharing options...
CoastalWx Posted December 15, 2019 Share Posted December 15, 2019 That's fine. I'd take 2" and run. Would be nice for the incoming cold. 1 Link to comment Share on other sites More sharing options...

Prob be some minor glaze in spots...but this is frigid below 850-900mb so my guess is the non-snow ptype in the interior will be mostly sleet. There may be a thin band of solid icing just inland from the south coast of C/SW CT where the midlevels really intrude deeper but sfc stays below freezing? 1 Link to comment Share on other sites More sharing options...
CoastalWx Posted December 15, 2019 Share Posted December 15, 2019 Yeah if one were to believe the 3K NAM, it would melt the hydro meteors, but it's a large area of sub 32F area that it falls through again. I agree, seems like maybe the area in srn CT and RI just inland may get decent icing. Link to comment Share on other sites More sharing options...
HoarfrostHubb Posted December 15, 2019 Share Posted December 15, 2019 RPM would make me very happy. Unfortunately it is about as consistent as the Patriots offense Link to comment Share on other sites More sharing options...

I think a lot of the mesos put out their own ptype or even snowfall/ratio. I'm a little out of the loop with the details of what models can do what over the least 5 or so year, but that was at least my understanding.

I'm a prime candidate for this statement right now, bad icing tends to occured in this area last year on multiple storms... Anybody remember this? Terrible situation. 12Z RGEM coming out now just able to look at the CMC-Ptype page, looks like the initial thump cut way back. Precip shield is much lighter on the front end but thats only to hr48. 1 Link to comment Share on other sites More sharing options...

RGEM def has its own ptype algorithm unlike, say, the Euro. It's why it's one of the few TT maps that doesn't say "includes sleet" in the snowfall. So I'm pretty sure meteocentre just rips the liquid straight from the RGEM ptype parameter. 1 Link to comment Share on other sites More sharing options...
CoastalWx Posted December 15, 2019 Share Posted December 15, 2019 I think the mesos like 3K NAM, HRRR, and maybe RGEM explicitly predict snow. That said, I still find some of the output a bit strange at times. 1 Link to comment Share on other sites More sharing options...

I know the ICON and 3k NAM have their own as well. So I guess you can throw the herpes into that mix as well. weather.us has some rare Euro maps you won't find elsewhere. There's a significant weather map there which makes me think the euro does put something out for ptype...since the maps include t'storms and fog as well. I doubt the US vendors are getting ALL of the euro data. I mean weather.us has heat flux, moisture flux, ozone, etc. Link to comment Share on other sites More sharing options...

One storm that comes to mind that it latched on to early and infact did not waffle back and forth as it usually does was Jan 23rd 2016 blizzard. It actually did pretty well, it was a hair too far north with the heaviest qpf but overall a good performance from what i remember. Link to comment Share on other sites More sharing options...
