Now, it’s a 1-2 inches of snow and sleet event even up here in Rockland, less than an inch for NYC 3-4 days ago I could see that because I felt there would be a strong massive WAA push but the system just dampens too much as it exits the Oh Valley leading to that initial slug of moisture dying out. I'm not sure why JB still felt that good yesterday 1 Link to comment Share on other sites More sharing options...

And snow accumulation and depth aren't even directly modeled geophysical parameters. The ECMWF models literally dozens of parameters across the entire globe and people only consider one derived parameter from an individual run for a very localized area when evaluating model performance. The funky IVT snow event was missed by all the models but the Euro up til the day of the event was the best and probably still did best that day out of all the models Link to comment Share on other sites More sharing options...

This is due to the euro being really bad so far this year in the 2 to 5 day range. Heck it was even really bad last event at 12z the day the event was ongoing. And how good have any of the other models been? The Euro has verified pretty well IMBY the last 2 events. 24-48 hrs prior It had me getting a total of 11 inches in early Dec and that is what I got. It had me getting 2 inches from the frontal wave and I received 1.5. With this system models have been all over the place quite frankly. 1 Link to comment Share on other sites More sharing options...

If you looked at the snow maps then it seems like it has been bad but its by far led the way with this event the entire way. I'm not sure if I'm correct but most of the snow maps that are put out there are mostly at 10:1 ratios. It's hard to get those ratios in most events. So people are looking at the maps and not taking the lower ratios into consideration. 1 Link to comment Share on other sites More sharing options...

The new RGEM shows it really well, it barely has an inch of snow in my neck of the woods now Link to comment Share on other sites More sharing options...
CIK62 Posted December 15, 2019 Share Posted December 15, 2019 GFS LAMP keeps starting tomorrow's precipitation later and later. Temperature now up to 37 when precipitation starts during PM Hours. Several hours ago it had something happening while it was still 32 at the surface. December 22 looking strung out again, more like a frontal passage than a cohesive storm. Core of it goes south, but WAA damage will happened if this is the arrangement. Link to comment Share on other sites More sharing options...
Brasiluvsnow Posted December 15, 2019 Share Posted December 15, 2019 To me and I am just a novice but it seems that the models have been a roller coaster and I am talking with the previous events as well. I see you guys are saying this one particular model or that model nailed it with previous storms but again to me the models have spit out different solutions from day to day never mind run to run. Again that is just my opinion and what I have seen---in other news before any of us proclaim which model was all over this Monday / Tuesday event shouln't we wait until it actually happens or is over to say that, I mean again if you looked at yesterdays runs compared to todays they are different and my guess is the overnight runs could easily ( they shouldn't in theory but in likelihood could ) not look anything like todays or yesterdays runs.

NycStormChaser Posted December 16, 2019 Share Posted December 16, 2019 Surprised more people aren't talking about the ice for areas north of here. Could be pretty significant Sent from my SM-N950U using Tapatalk Link to comment Share on other sites More sharing options...

It is night and day expansive with QPF from 00-06Z vs the 12Z run. the 12Z run had zilch from 00-06Z for HPN. This run looks to have .25-.30. At 850 it was also a shade cooler and not as far north on the warming from 00-06Z. I don't see what is doing at 750-825 though so it could be mostly sleet 1 Link to comment Share on other sites More sharing options...

Yea the 850 push was not as strong as this run. Looked only a little north of I84 at its warmest point, if it pans out like this I think this could be mostly snow/sleet inland. I also think happening overnight keeps everyone colder, could be a Snow/Sleet to ZR event even for the immediate suburbs Link to comment Share on other sites More sharing options...

There may be some dynamic cooling as frontogenesis increases late tomorrow evening, but with the SE ridge amped up like it is on the EPS below, it will be hard to avoid torching the layer just above the surface. This could be a fairly bad ice storm near White Plains, NNJ, southern CT imo. 2 1 Link to comment Share on other sites More sharing options...
eduggs Posted December 16, 2019 Share Posted December 16, 2019 I agree on the ice threat. 800mb temps still warm to about 5C right up through the mid-Hudson valley. The 0z NAM increased the QPF with the first 6 hours of the main WAA push so there's a little snow thump there. But after that mid-level warmth wins out like previous runs. NW NJ keeps showing up as a focus area for icing potential. But I think lots of areas from NEPA to SENY through SCT are at risk for some moderate ice.

HVSnowLover Posted December 16, 2019 Share Posted December 16, 2019 RGEM continues the colder trend, looks like a pretty impactful icing event for many in the area may be unfolding 1 Link to comment Share on other sites More sharing options...
