Wilmington, NC hasn't seen a 6" snowstorm since December 1989. Remarkably, Wilmington had a 8.6" snowstorm on January 13-14, 1912 and a 9.8" snowfall on February 10-11, 1912.

UlsterCountySnowZ Posted January 5, 2017 Share Posted January 5, 2017 Total euro precip doesn't amount to much, eastern Long Island sees an addition couple of inch, nobody else accumulates... maybe a dusting to 1" for NYC areas Link to comment Share on other sites More sharing options...

The two streams on the Euro are completely disjointed. The GFS was a heck of a lot closer than the Euro is. I'm not sure what people expected with no blocking and an overall progressive pattern.

Holly had a nice updated AFD talking about mesoscale banding. As people on this board would likely know, with mesoscale banding, pinpointing the heavier bands is nearly impossible (much like convective t-storms in the summer). In scenarios like this, some small areas (like part of a couple of counties) could get 3-5" of snow, while everyone around them could get 1-3" of snow. http://forecast.weather.gov/product.php?site=PHI&issuedby=PHI&product=AFD&format=CI&version=1&glossary=1&highlight=off .SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/... 930 AM Update...We are in the process of analyzing the incoming 12Z model guidance. Hourly temps, PoPs and Wx grids were already updated for tonight and are included in the 930 AM ESTF. We anticipate sending out an updated snowfall map and issue any winter weather advisories before noon. The 12Z NAM, latest RAP and HRRRx (which goes out far enough to capture the entire event) indicate a band of heavier snowfall (2-3") that develops late this evening near the Mason-Dixon line in SE PA/N Delmarva and expands northeastward into central NJ overnight. We continue to see a trend to the northwest with the placement of the mesoscale snow band. Additionally, the models show a local min in precip between this leading snow band to the north and heavier precip offshore, which is where we previously forecast the axis of heavier snowfall to occur. A period of moderate snow on the western edge of the precip shield from the coastal low may occur late tonight or early Friday morning over coastal NJ but it`s still a very close call. Exactly what I was expressing last night. The general snow maps are smoothed out. It's all about where banding sets up. I think it's more like a general inch around the city with 4" in the best banding Link to comment Share on other sites More sharing options...

Very possible however my red flag for this event, is zero ensembles support, the EPS and Gefs are pretty unanimous on a near miss solution, which is right in line with ggem/GFS/nam/euro.... no reason other than staying hopeful to think this thing has what it takes to get out ahead of the energy dropping from Canada allowing for the trough to dig and phase in time to bring it up coast...I'm not sayin it's impossible, I just think it's not gonna happen for anyone west of eastern Long Island... best place to be is ELI, and I think they could overperform, but I think they overperform with wave 1 not wave 2... Also keep in mind single digit dew points, and a very cold air mass, with a progressive flow, and late phase... your gonna need to see some decent DBZ overhead otherwise your LE pours virga only shot we have is models are wrong on the timing and we get an earlier phase Link to comment Share on other sites More sharing options...

All models show measurable snowfall from both waves for NYC East and South, not just Eastern Long Island. Just because NYC wont see half a foot doesnt mean it was a whiff. The UKIE, GFS and EURO, our best models, all took huge jumps NW. Yes, not to Ulster County, but the 12z suite puts the coast in the game for an advisory level snowfall. The Ukie gives Eastern LI a warning level event for Wave 2. Link to comment Share on other sites More sharing options...

donsutherland1 Posted January 5, 2017 Share Posted January 5, 2017 Comparison of the 1/5 0z and 12z runs of the RGEM. Ratios should be better than 10:1 (probably 12:1 to 15:1 depending on location): Link to comment Share on other sites More sharing options...

BxWeatherwatcher Posted January 5, 2017 Share Posted January 5, 2017 track the lows,1 developing by the delmarva,the other in georgia and the lone impulse in ill which actually come in to play tonight. someone along the coast is gonna get clipped with a healthy band later on when everything really starts blowing up along the coastal plain..

It finds a nut once in a while but it was clearly overdone yesterday with the 3-5" type stuff it was showing on Long Island. 1-2" maybe locally 3" is probably right near the coast and less than 1" in the north and west suburbs. It does look better for wave 2 than 12z and that brushed moderate snow on the coast. Link to comment Share on other sites More sharing options...
