HRRR3 Model seems to have Precip Type issues by Noon tomorrow for all of LI, NYC, S. Shore of Conn. and all but upper third of NJ.        I think it is an experimental output though.     Comments.         Choose correct Sector.      Check Radar and Winter       Use the > to go as far as it can on the 23Z Run, passed the Red boxes.

While you cant discount it, I believe it is running too warm.  i dont see a mix line running that far northwest, i can see the mix line getting north of eastern LI but thats about as far as it gets towards western li/nyc

As others have stated the hrrr seems to be best under 6hrs of runtime. Past that the differences are pretty inconsistent.

It definitely won’t be that far northwest by noon. Although some models do have the mix line approaching the region overnight with the overrunning precip but it will crash once the coastal takes over.

Gfs pops another little low on Tuesday 

Gfs has snow until Wednesday morning

I mean I know it's possibly a faux pas at this juncture to post snow maps, but I'm curious what it shows with that other little low on Tuesday

So Noaa just lowered our totals in Monmouth (Tinton Falls, a few miles from Red Bank) to less than one inch on monday. Everything on here is saying differently, I hate IMBY posts but I will be going to work if it's only going to be an inch of accumulation. Any Ideas ? 

i really don't see what would support an inch of snow or less on monday anywhere in monmouth

Comparing 0z to 4z HRRR it seems to be moving the low east a bit. Also more impressive with snow totals. Has SW CT at 7 inches by 15z vs 5 inches. Low is stronger as well.

HRRR is completely and utterly lost on this one. Just look at the radar sim. It has no CCB and precipitation field to the west of the low. Not gonna happen, it's an extreme outlier. Even the other mesos whole disagree.

The gfs shows what appears to be the low stalling  and strengthening through tuesday right off belmar nj

Curious if the precip will remain as intense.

 

Thoughts?

No.  The system occludes as well as the flow aloft being almost entirely NNE off land at that stage with no Atlantic moisture influx.  You also will have probably poisoned the mid levels with some milder temps leading to poor snow growth.  Some isolated areas of accumulating snow will happen later tomorrow night and early Tuesday but over 1-2 inches additional accumulation won’t occur many places at all
