clarks green snow Posted December 15, 2016 Share Posted December 15, 2016 Squall came through around 7AM and dropped a quick 1/2 to an inch of snow mostly north of I-84. Accidents everywhere. 13 degrees right now and looking to head down close to 5 tonight. Friday night and Saturday AM look interesting up here. Mets are all over the place with most saying 3-7".

Jmister Posted December 16, 2016 Share Posted December 16, 2016 It does look increasingly like a slop fest with less of a snow thump in the beginning. The NAM sounding for Sat 12z shows a ridiculous inversion...temps go from -7C at the surface to 3C at 850mb. This sounding looks like sleet to me, but any rain that falls, no matter how hard, will freeze right away at those surface temps. State College maps show primarily snow, but these were updated at 10am. I bet the update will push more towards ice and sleet. However, the WPC is realizing the icing concern.

Jmister Posted December 16, 2016 Share Posted December 16, 2016 Speaking of, CTP in their update is moving the threat away from snow and more towards ice. Updated 7:30pm Link to comment Share on other sites More sharing options...
Blizzard of 93 Posted December 16, 2016 Share Posted December 16, 2016 Most models still show 2-4 inches of snow for most of us before the changeover to ice. What do you guys think about the odds of the potential for a secondary wave on Sunday that could possibly change us back to snow ? Link to comment Share on other sites More sharing options...

canderson Posted December 16, 2016 Share Posted December 16, 2016 .6 would be horrible bit not destructive really, leafs are gone ahd wind will be balm so it wouldn't be the end of the world. 1"+ ice?

CarlislePaWx Posted December 16, 2016 Share Posted December 16, 2016 Not saying I buy into the 0.6" of ice, however, i'm pretty sure NWS says that even 0.50" of ice accretion is a major amount which can cause significant tree damage from the weight of the ice. It only takes the potential of 0.25" of ice to produce a winter storm warning. My expectation is that we will wake up tomorrow morning to WSW for snow (light amounts, probably less than 2") > sleet > long duration ZR. NAM gives the LSV no measureable snowfall from tomorrow night's initial precip. That does seem a little odd. My immediate area tends to be very slow to scour out the cold, (for this part of Cumberland County), so I would not be surprised to see ZR hold on longer.

I'm not being a deb, but far too often these events under-perform snow-wise around these parts. Rarely do we pick up more than a slushy inch or two before the flip...I guess time will tell as each event can provide surprises both good and bad. As expected, accumulation totals have been steadily lowered. Horst now saying a coating up to 1". Link to comment Share on other sites More sharing options...
AllWeather Posted December 16, 2016 Share Posted December 16, 2016 I'm increasingly becoming more concerned with the icing potential here in PA. The globals have come around to keeping temps AOB freezing for everyone here in this forum into about 15z tomorrow. During this time, around .10" QPF falls at MDT as snow per a blend of the guidance I look at frequently. Then it flips, with a period of IP, and an even longer period of FZRA. After the flip per soundings, roughly a quarter-inch (or more) of FZRA falls at MDT...other locations have quite a bit more. The cold air we have now is bitter cold, and the ground is freezing at this point. Having temps at 32F or even 33-34F in the boundary layer will still probably mean freezing rain as the ground is just so darn cold. That's concerning. Oh yeah, we'll probably have some snow too, but unless you're awake around sunrise in SCPA, you may not see it fall! Link to comment Share on other sites More sharing options...

Many Rodeo's in..... With that said, the 850's are scorching hot by 12z so that layer may be getting quite thin.....but it only needs to be "thick enough".... Ice skates for many.......

At least there is some energy scooting SE w/ the frontal passage that may give it a shot as temps crash back towards normal. All good.

Downsloping (warming) winds either dry things or warm it up (or both). I've personally never seen cold air catch up in an anafrontal situation to change over to snow SE of the high terrain of C PA.
