Well, I think today it helped our snow fell primarily before or around daybreak....it will be interesting to see what snow totals are like today up in northern Jersey, NYC, Long Island with snow falling during daylight hours due to solar radiation (the sun's rays shining through the clouds, even on cloudy days). I always feel like a little accumulation is wasted when that happens unless it is an intense storm. With that said, after thinking 1.5" today, and getting 2.25" I'm thinking around 1.0" tomorrow. I tend to be a bit conservative in my guesses, so we'll see....

1" richer than we thought we would be!:snowman:

Has been alot of melting in the city and eastern areas but much of NE NJ has gotten 3 to even 5" in spots. Temps are in the 32-34 range mostly

Cool, just what I wanted to know. There to in NE NJ, some of the steadier snow fell when the sun was just rising, so you guys got a head start, for NYC/LI they are battling temps. in the mid-30s and the sun at its highest point of the day through the clouds. Not the best combo. for accumulating snow.

The WRF-ARW develops a 989 mb low about 50 miles off Cape May at 30 hrs, then deepens it to 987 mb at 33 hrs about 100 miles off Asbury Park, then at 36 hrs it develops a secondary low or broadens the original low and has two centers one about 150 miles offshore of Asbury Park at 986 mb and the second one about 20 miles off Asbury Park at 987mb , then it deepens that low to 985 mb about 50 miles offshore of Asbury Park, then deepens to a 983mb about 100 miles off Asbury Park, it then deepens it to a 982mb near the Benchmark at 45 hrs. Precip wise it brings an area from about Harrisburg to Baltimore, all of Eastern PA, all of NJ, all of CT, and SE NY state at least 3-4 inches of snow tomorrow, with possibly a more in Central NJ and possibly even more than that on Long Island maybe around 6 inches or so, and coastal CT could get a foot according to the WRF-ARW.

WRF-NMM shows a 0.75-1" stripe of QPF near Cape May. A good portion of SNJ sees 0.5-0.75" of QPF. Most of the PHL area sees 0.25-0.5" of QPF stretching all the way back to H-burg. By hour 33 a 990 mb low develops about 150 miles east of ACY. By hour 39 it's down to 986mb just east of LI. Heads almost due east afterwards.

I had thought that as well but the PNS had 1" at 11 AM and snow stopped falling then @ PHL.

PNS confirms 1.3"...
