pasnownut Posted November 7, 2017 Share Posted November 7, 2017 this may be what hes talking about, but as you cycle through both GFS and GEFS you cans see the potential for the trough to break down.....after the stemwinder moves out (which often happens). need to dig more tonight to see where things are. Regardless, its way too far out to worry attm, but nice to see the blues on the east coast. Nut Link to comment Share on other sites More sharing options...

canderson Posted November 7, 2017 Share Posted November 7, 2017 Just a raw day. As noted, decent sleet mixed in today in Harrisburg. May get some flakes later this evening even. Link to comment Share on other sites More sharing options...
Itstrainingtime Posted November 7, 2017 Share Posted November 7, 2017 Had some sleet bounce off my bald head a few minutes ago down this way too. Pretty amazing how we went from a way, way above normal pattern to this so quickly. Not complaining in the slightest. Bring it! Link to comment Share on other sites More sharing options...
heavy_wx Posted November 7, 2017 Share Posted November 7, 2017 Still snowing here with modestly reduced visibility. Mostly wet surfaces out there with decent-sized melting aggregates. Link to comment Share on other sites More sharing options...

Mostly wet surfaces out there with decent-sized melting aggregates. Eric Horst, meteorologist with Millersville University tweeted this morning that we were treated to some "Kelvin Helmholtz" clouds. Surely, you of all people can fill us in on what Kelvin Helmholtz clouds are. I know my cumulus, stratus, cirrus, etc., but this is new to my weather repertoire.

heavy_wx Posted November 7, 2017 Share Posted November 7, 2017 KH waves are beautiful! Here's a particularly dramatic example from Alabama a few years ago: Basically they form when there is a vertical gradient in wind shear and/or temperature. A small, random disturbance can then grow to produce the waves; these waves are visible to us if the temperature and/or shear gradients occur near the tops of clouds, as the cloud basically traces out the waves. They're actually fairly common on fair-weather days after a cold frontal passage if you look out for them. Link to comment Share on other sites More sharing options...

Wasnt sure if I had seen those on the horizon or not, couldnt tell whether it was from factories or was actual clouds but did see Undulatus Asperatus clouds today quite vividly.

MAG5035 Posted November 7, 2017 Author Share Posted November 7, 2017 Just got back from working up north above I-80 today and it was quite a nice drive home. First flakes and measurable snowfall in the books today in the backyard, about 0.7" on the colder surfaces. There was a mini dry slot that had moved into the Altoona area before I got home so may have been more like an inch a little bit ago. At the top of Wopsy Mountain above Altoona where it gets up around 2500' there's about 2.5" on the ground up there. Talk about a spur of the moment event for the central mountains. For as relentlessly warm as this fall has been this is literally the third time I've seen it snow since the November 1st Nor'easter in my travels around the general area here. I was working above Dubois last Wednesday and got to see that bit of snowfall. Here at home, I have a new vista this year (I moved haha) Top of Wopsy Mountain above Altoona (approx 2500' elevation). This is about 5 miles from my house. Link to comment Share on other sites More sharing options...

Voyager Posted November 7, 2017 Share Posted November 7, 2017 Had about 1.5" on my Jeep when I got back to Hazleton from running two Tioga's today. Talk about a lot of miles. Anyway, it seemed as if the best accumulations were above 1,500 ft here along I-81. The snow level itself was about 1,000 ft as Hometown had a coating, but one mile down the hill in Tamaqua, at 800 ft, we had nothing. Link to comment Share on other sites More sharing options...
CarlislePaWx Posted November 8, 2017 Share Posted November 8, 2017 Sleet first started mixing in with the rain around 2:30pm here. Temp was around 38 at the time. By 4:00pm the temp had dropped to 35 and it was snowing with huge wet flakes and beginning to stick on the grass, my deck, and snowboard. By 5:00pm temp bottomed out at 33.4 degrees and the snow varied in intensity from almost nothing to big fat flakes. Precip-wise I picked up almost 0.40" of liquid. The snowfall was pure slush, but I am going to record it as 0.1" officially. It was actually more, but was melting while it was accumulating, making it almost impossible to measure. What a sudden change from yesterday with a high of 64 degrees! Also, this is fairly early for the first recorded measurement of the season. All-in-all a pleasant "surprise".
