RedSky Posted February 17, 2015 Share Posted February 17, 2015 Is that 20-30 DBZ band reaching Allentown, PA now putting down accumulating snow? I would think it would be. That band has moved about 30-40 miles to the North while moving generally to the NE. If the band holds together and maintains latitude, moving east along 78, that would give me some snow here in the Edison area (about 10 miles south of the northern edge of the current band) and hopefully give snow to folks as far north as the southern half of NYC/LI. Of course, the band could fall apart or start edging SE, too - I'm not an expert in this, just looking at current trajectory and projecting... I am in the center of that band and it just started flaking, not too impressive no coating yet Link to comment Share on other sites More sharing options...
Winter Wizard Posted February 17, 2015 Share Posted February 17, 2015 Moderate snow, definitely the best rates of the night so far. Flake size has noticeably increased. Coating. Link to comment Share on other sites More sharing options...

It's moistening up the air quick. Now a steady light snow with pretty big flakes. Continuing to pick up in intensity. Going to stay up a bit longer to see how this pans out.

Treckasec Posted February 17, 2015 Share Posted February 17, 2015 Hmm, I stand corrected from what I said earlier. Looks like I'm getting the band too, air is quickly moistening up here. Temp: 13 DP: 8 Humidity: 74 ( changed to 80 in just 6 minutes or so ) Oh my, just beautiful. No melting, and I can clearly see the shape of the snowflakes on surfaces. Classic shape. Falling at a slightly steadier pace compared to last time, very nice. I'd say a coating right now. I didn't think I would even have this much snow until like 3 AM, lol. We have got to fight this dry air, we have some potential, but half of the snow we could of have has been wasted. Link to comment Share on other sites More sharing options...
