right near my old stomping rounds....i use to work at the corner of adams lane and rte 130. the building across from Margaritas pizzeria.

good luck down there!

Just got to my friends in West Windsor. Route 130 and Church Street. She wanted to put salt out. I told her that would ruin the shoveling experience tomorrow.

Realizing now i should change my location back to Edison.

Thats right! I was saying something similar today to some other Meteorologists on campus. A few days ago, it didnt look like we have enough cold air. Now we do and we have snow hours away. Bring it!

That is why any declarative statements about snowstorms more than three days in advance (especially in this part of the world) are quite often wrong.

Everyone worries about mixing, but I wonder if a persistent dry air pocket will put someone in a localized screw zone? Some of the high res models clown maps have had odd lollipops and accumulation deserts in places where elevation wouldn't account for the discrepancy.

If you look at the RGEM animation...there appeared to be light snow ongoing in eastern NYC and Nassau for several hours while everyone else was in at least moderate snow...somewhat weird...

through 15hours on the gfs, 850 line well south of the city

i think this comes in line with all the other gfs runs precip amount wise and probably colder than 18z

at 18z 850 line right over nyc cutting LI in two north shore south shore, give or take

precip amounts are still in the .30 to .40.

I know both in Mt Holly and Upton CWA's past few years there have been irregular accumulation patterns both in some of our bigger events and in marginal ones...some due to hours of lighter snowfall due to drier air streaming into a narrow region and eroding the precip shield, other times in the marginal events some areas taken longer to moisten and losing precious hours of accumulating snow, then basicallly going right to mix....there was one where DC got 2-4"...my location in south Jersey got a dusting...and central jersey and points north got 4-5" due to losing hours of precip to dry air, where that same area of dry air drained down to dc leading to evaporative cooling that allowed them to stay mostly snow.

That's definitely an odd solution... weird thing is that the HRRR/RR also showed this before, they're starting to back away from it, instead showing a 30-35dbz band coming through, but the RGEM now shows this:

NAM shows the same thing. Nothing to freak out about. Might be picking up on some dry air or developing banding.

Good thing that it's just a little dry slot, probably won't have any huge impact on the total snowfall... at least it's actually going to snow and accumulate without a changeover, that's good enough by itself. Might be a while until we get another snowstorm like this one.

its draining dry air down the hudson valley, thats why. it happens all the time with a 1030 high over upstate ny. It could eat a few flakes IF its real.

I stand by what i said earlier, SWFE don't tend to have much virga.
