Same here about 2 inches in Monroe, CNJ

[Animal]

Second wave will have me up all night watching.

This hobby rules.

 

What 2nd wave? Radar looks bad out west.

[Absolute Humidity]

3.0" even in Ewing... that's mi madre

Nice pic Ray. 2.9" here on the board. Up to 4" on the grass with air pockets.

What 2nd wave? Radar looks bad out west.

Searchlight casting

for faults in the

clouds of delusion

Radar should blossom soon

[ChescoWx]

Latest Wxsim has a mix picking back up again later this evening transitioning to ZR toward midnight. Unfortunately the trend continues to be colder and it now has temps staying below freezing here in NW Chesco till almost 9am - by that time another another 0.71" of frozen has fallen. Looks like another inch or 2 of snow may fall before the total change to ZR. So far 3.8" on the board here. The Wxsim also paints another 2 to 4" of snow on Tuesday late AM

What 2nd wave? Radar looks bad out west.

Wrong direction, look southwest.

[Animal]

Wrong direction, look southwest.

 

I also looked SW

[famartin]

I also looked SW

That blob down in western Virginia and southern West Virginia is the next round.

[Heisy]

What 2nd wave? Radar looks bad out west.

 

Look into VA, its already quickly shooting NW from there.

[Heisy]

Its actually making a b-line towards us just like this morning. If temps hold in the burbs it could get pretty bad

[NJHurricane]

Ground truth confirmation for the PHL/national park measurement...Took a walk around my home base National Park NJ...as small as this town is there was a clear one inch gradient, heavier towards the river...I took some rough measurements near the Red Bank Battlefield monument park...within sight of PHL control tower...assuming the observer is on that side of town I concur with the official measurement...my first real snow since we moved from one town over in Woodbury, when we moved to our last location in Woodbury was the microband that hit the airport and Gloucester county several years ago...I need to move every year lol

[KamuSnow]

6.75" in Concord Township, PA  - an awesome event. Roads were rough, warm ground underneath seemed to help make a nice layer of ice on main roads with the heavy snow rates. There may be enough snow to survive the rain tomorrow and stick around for the rest of the week. Lights look good with snow on the ground!

[noctilucent]

I'll go with 3.3" here in Warrington, Bucks County, PA.....though I measured pockets with as much as 4.5".

 

Temp is 26.7, with a light ENE wind....surprising that the wind has not shifted to a more southerly component or the temp has not risen.

I have a trip to North Jersey tomorrow (inland)...and earlier today I figured it would not be an issue....now....I guess I'd better check first before taking off.  

[Heisy]

Ray are you concerned for icing problems in the burbs late 2nite/early tomorrow? I think the city might get a brief glaze, but thats about it. 

[famartin]

Yes icing looks like a significant problem later on.  I haven't looked closely at it though, I must admit.

[Violentweatherfan]

light mist - rain now in Levittown PA

[Fields27]

Little over an inch in northern Berks. Congrats to those of you who cashed in down towards Philly! I'll be up late to see how this 2nd round plays out. Thinking tomorrow morning is going to be an absolute mess. Currently sitting at 25*

[Allsnow]

wow at these numbers

congrats guys!

Yes good stuff. My brother in Tom's River says he got 10".

[MGorse]

5.1 inches of snow in Delran, NJ. Seems to be some freezing drizzle occurring now.

 

Today was probably the most rapidly changing shift I have worked in my NWS career so far. We saw the banding setting up across northern Maryland with moderate to heavy snow in the obs under it. We had a feeling there would be a burst of snow, but just wow!  The thermal gradient was quite impressive aloft from our area southward and that allowed for rapid strengthening of the frontogenetic forcing. It appears there was some elevated instability within that band which helped with the 1-3 inches per hour snowfall rates. The HRRR this morning actually picked up on that band and then did fairly well. After looking at the totals, just wow! I smell a case study on this bad boy. At least I got to break out my snow thrower. I am glad I am off from work tomorrow as I am exhausted and probably have less hair than I did early this morning.

[Allsnow]

Good work today mike! Very rapid changing event!

[MGorse]

Good work today mike! Very rapid changing event!

 

Thanks. PHL was not happy when I spoke to them late this morning with an update. What a mess!

I knew something rare was up, seeing how heavy those rates were in the beginning of the philly game. 

 

freezing drizzle could be a traffic nightmare tonight for N and C NJ. ..

Wow, that's pretty amazing. I saw the Euro and some other high Rez models paint a 3 - 5" band last night, but just wow at some of those totals.

[famartin]

The 3.0" of snow melted to 0.28" liquid back home.

[RedSky]

Have had snizzle since the snow stopped
