Sleet now being reported on a line from just south of Allentown, Pa to just north of Trenton and eastward

You can see a weak LP trying to develop around the Delmarva:

All snow out by me right now on LI but I can see the R/S creeping in from the SE.

How much snow do you have out ther right now, Scott? I'm back in Fishkill now which is about ten miles south of Poughkeepsie, and we have jack-squat lmao maybe getting close to an inch.

Def not as many early birds as there are night owls.

FINALLY SOMEBODY WHO HAS A DUAL-POL PRODUCT Ahahahaha I've been trying to splice radar "bright bands", in quotes because returns aren't that bright, surface obs, and the meso-analysis to get an approximation ahaha

by **Frank_Wx** Sat Dec 17, 2016 6:58 am

I felt like models did not have a changeover until 9-10am. Seems fast

26.2* with moderate snow falling. Avg measurement 2.25" so far. Even if it stopped here I'm happy.

That's why I kept my forecast the same; I mentioned that in my discussion I thought the models were much too slow. We'all see if that holds true or not. How much do you have so far?

by Guest Sat Dec 17, 2016 7:04 am

Just came back in. 2 1/2" here in Syosset and coming down good right now. Headed your may sroc4. Can this keep up till 10:00 am? if it does we get over 4" easy and maybe approach the HRR totals spit out last night of 3-5"

by **rb924119** Sat Dec 17, 2016 7:05 am

Finally tapping into the dendritic growth here in Fishkill lol wooooo

by **sroc4** Sat Dec 17, 2016 7:07 am

Frank how did you get the animation loop from radar scope to load? I am trying but it says either file to large or corrupt.

by **snow247** Sat Dec 17, 2016 7:08 am

Moderate snow. Eyeballing it looks like I'm approaching 2" here.

by **Frank_Wx** Sat Dec 17, 2016 7:08 am

Couple of things

1. Winds still from the North in northern NJ. R/S should stay S&W for another 1-2 hours, though I see its moving quickly. We'll see.

2. Besides immediate coast, surface temps are cold as heck still. Looking at a prolonged wintry event.

More ice/sleet mix now here. A good inch to inch and half on ground. Temp has rose to 30° was at 26° at 5 am. So temps are on the rise

Lots of busts in PA, but I'm approaching 2 inches.

Your longitude is helping right now. Long Island is likely to end around 4 inches. Could see 5. Good luck!

On Facebook people in Allentown area said they have coatings to 1 inch. I definitely thought more for them. NJ/NYC seem to be on track.

by roccuweather Sat Dec 17, 2016 7:17 am

7:15am and two inches in Belleville with moderate snow. I drove on the parkway between Union and Essex at 5am and it was just wet. By 6am both roads were completely snow covered, but passable at slow rates. Surprisingly a lot of cars on the road. Saw salt trucks out but did not pass any plows on my 45 minute trip.

by **skinsfan1177** Sat Dec 17, 2016 7:18 am

Frank your map spot in for my area

by **sroc4** Sat Dec 17, 2016 7:18 am

Getting hammered right now. Gotta smell the rain to get the best rates.
