mappy Posted November 26, 2013 Share Posted November 26, 2013 PWS near my house are all 31-32 with rain. I suspect its freezing on contact to something. Should have stayed home! Link to comment Share on other sites More sharing options...
NortheastPAWx Posted November 26, 2013 Share Posted November 26, 2013 Is that 50mm of ice showing up on that map? That would be destructive... Link to comment Share on other sites More sharing options...
skiier04 Posted November 26, 2013 Share Posted November 26, 2013 Ok RGEM just is insane. I hope to god this would never happen. lol Been pretty consistent with that too over the past day or two. Scary... people are underestimating things right now here because the roads aren't too bad despite ~3" on the ground. If we go to ZR things could get really nasty out there.

EasternUSWX Posted November 26, 2013 Share Posted November 26, 2013 Is that 50mm of ice showing up on that map? That would be destructive... Yes. lol. That's like 1.5-2" of freezing rain. There is no way... cause if so well ya we fooked. Link to comment Share on other sites More sharing options...
pawatch Posted November 26, 2013 Share Posted November 26, 2013 Just made a pit stop in Milroy on the way back to Bellefonte. 1.5" on the ground with steady snow. 322 is messy...now to run the Seven Mountains gauntlet.Good luck Penn! Not fun with all that weight.Been snowing here since about 1:00 am maybe 2" on the ground. First real snow of the season for me. Link to comment Share on other sites More sharing options...
canderson Posted November 26, 2013 Share Posted November 26, 2013 Yes. lol. That's like 1.5-2" of freezing rain. There is no way... cause if so well ya we fooked. I've seen 1.25" zr once in my life, New Years Eve/Day 2001 in East Texas. It was catastrophic to entire forests, utilities and some outbuildings. Anything .75" and over when talking about zr is extremely bad. Hell, .5" will cause major issues by itself. Link to comment Share on other sites More sharing options...
djr5001 Posted November 26, 2013 Share Posted November 26, 2013 Surprising thing is temps are still falling. Was at 34 at my house now 31.9. A few places might get some pretty bad ice. Temperatures finally getting close to dew point here out east... drop will be temporary before rising just a few degrees this afternoon Link to comment Share on other sites More sharing options...

Hell, .5" will cause major issues by itself. the model is assuming all precip freezes too... the rainfall rates would be too high for all of it to accrete but would still be significant if .25-.5" instead of 1.5-2" anyway Link to comment Share on other sites More sharing options...
EasternUSWX Posted November 26, 2013 Share Posted November 26, 2013 Temperatures finally getting close to dew point here out east... drop will be temporary before rising just a few degrees this afternoon RGEM hold 32 or below till about 11pm. NAM till about 8pm. We shall see. 31.6/27.3 in Greencastle. Getting icy. Link to comment Share on other sites More sharing options...

Heavy freezing rain falling at 30F and above runs off a lot of the time before it freezes. So the actual accretion will be less than that. Also, there's no cold air source to keep replenishing the cold air. So a lot of locations might just rise to 33 and have plain rain. Link to comment Share on other sites More sharing options...
sauss06 Posted November 26, 2013 Share Posted November 26, 2013 another concern i have, many leaves are still on the roadways in this region, last night i saw almost every storm drain still blocked. If we get the rain they speak of, could be trouble later. Link to comment Share on other sites More sharing options...

EasternUSWX Posted November 26, 2013 Share Posted November 26, 2013 31.4/27.7 now in Greencastle. Icing up. Trees and cars covered according to my friends. Link to comment Share on other sites More sharing options...
sauss06 Posted November 26, 2013 Share Posted November 26, 2013 It's a steady stratiform rain so there won't be much to worry about. Perhaps. But knowing my area, blocked storm drains create issues for certain areas in my township and it doesn't take alot of rain for that to happen.

Jmister Posted November 26, 2013 Share Posted November 26, 2013 Being in Philly for the week, of course there would be quite the interesting storm unfolding for Central PA! Just realize that those ice accumulation maps the RGEM is spitting out are highly unlikely to occur across 90% of the area it shows. Simply because moderate/heavy rain will not be able to freeze quickly enough with these marginal 31-32F temperatures. Areas just to the west who will stay a few degrees cooler and sit in less heavy precip has a chance for more serious ice accrual. Link to comment Share on other sites More sharing options...
Laurel Highlands Wx Posted November 26, 2013 Share Posted November 26, 2013 Measured 2". Temperature is 34 so unless the rate of snow picks up here will be tough to get much accumulation until later. Link to comment Share on other sites More sharing options...
Mallow Posted November 26, 2013 Share Posted November 26, 2013 Snow has already changed over in Johnstown and Altoona, ahead of schedule per the 12z NAM. This means it's probably only 2 hours away or so from changing over to ZR here in State College. Link to comment Share on other sites More sharing options...

CarlislePaWx Posted November 26, 2013 Share Posted November 26, 2013 Currently at work in Mechanicsburg. My PWS at home currently measuring 30.7/27.9 with light freezing rain. I know it is freezing because my rain gauge says 0.00". Earlier today I recorded only a dusting of snow at best. Not even 0.10". Cars were coated and my deck out back and that was about it for areas with any accumulations. The area between Zack (in Greencastle, about 25 miles southwest of me) and me in northern Carlisle typically hold on to the cold almost the longest in ZR situations in the Blue Mountain area. It will be interesting to see just how long we stay below freezing. My guess would be that as soon as the heavier rainfall arrives the temp will slowly rise up to and then above freezing. I'm wondering how much snowfall we might see on the back end tomorrow. I have plans to travel east to NJ for Thanksgiving with my sisters and we are supposed to depart around 2:00 tomorrow afternoon. Wonder what roads will be like around here. Not too worried about points well east on 78. Link to comment Share on other sites More sharing options...
Wmsptwx Posted November 26, 2013 Share Posted November 26, 2013 Wow bad zr on 15. 30 degrees and heavy rain. Just passed a bad wreck just north of Duncannon. Some day for a work trip. Link to comment Share on other sites More sharing options...
Mallow Posted November 26, 2013 Share Posted November 26, 2013 Radar showing some mixed precip already almost to Centre County. That was quick. EDIT: Based on radar, it should start sleeting/icing here in State College over the next 10 - 15 minutes. Link to comment Share on other sites More sharing options...
