sauss06 Posted December 5, 2013 Share Posted December 5, 2013 I agree...but I'm also having a hard time following because there are 2 separate threats that are being lumped together in essentially the same discussion. Those of us in the LSV (and those going to the Steelers game) are keying in on Sunday, while those north and west are focused on Friday night. Some great discussion and analysis...just hard to figure which event some are discussing. Yep, to me looks like we (LSV guys) will be rain Friday. And Sunday / Monday looks to start as Snow, a lil frzn then all rain. But what do i know. Zak told me on fb, he is thinking we get a couple inches, then .25-.50 ice?!?!

djr5001 Posted December 5, 2013 Share Posted December 5, 2013 Any predictions for icing in Millersville, PA? still tough to call right now... the icing threat is more of event 2 (Sunday/Monday) and event 1 (Friday/Saturday) results may determine how much of a threat there may be... I say there is a chance but right now a very small chance until things evolve a little more Link to comment Share on other sites More sharing options...
sauss06 Posted December 5, 2013 Share Posted December 5, 2013 "The SREFS are just little baby NAMs that are born three hours after mommy NAM is released from the psych ward."

jm1220 Posted December 5, 2013 Share Posted December 5, 2013 lets play find the front!! lol http://www.meteo.psu.edu/~fxg1/DEPHR/last.html http://www.meteo.psu.edu/~fxg1/DT24/t0.gif I do think sorta similar to last week that the areas that manage a changeover tomorrow night and keep this fresh snow on Saturday will see colder temperatures than the models are currently predicting and yes with a more established high lock in the colder air near the surface once again for Sunday/Monday unlike last week though... there will likely be a good bit of rain before a changeover instead of snow first then change over... will be interesting to see how easy the places that do changeover tomorrow accumulate As for warm sea surface temperatures... at the surface it impacts far eastern PA more than the Harrisburg region... I have seen in the past where a east/southeasterly wind pushes the cold air into the eastern side of the mountains and places like MDT wind up 5-10 degrees colder than Reading and east... aloft it certainly hurts any chance for snow and can warm 850mb level enough that if we see heavy periods of rain the warmer air can mix down to the surface a little... lighter rainfall and we could see temperatures close again for ice potential Once you're really into the ridges/valleys, the SE surface winds aren't a big factor. The cold air gets trapped pretty efficiently once you're into that terrain. I remember a couple of occasions when I lived out there when that was the case, yet temps stayed below freezing for hours and we had freezing rain/sleet. It's obviously a much bigger factor where I live now. Link to comment Share on other sites More sharing options...

If there is a changeover at the end to snow late Friday/Early Saturday for LSV area it will likely be a Trace to 1" at best... for Sunday/Monday .25-.5" ice may be a little extreme for our region... worst case scenario may be .1-.25"... the initial snow may be too light to reach the ground at first with the cold by dry airmass eating up some of the initial snow potential too Link to comment Share on other sites More sharing options...
whiteout Posted December 5, 2013 Share Posted December 5, 2013 FWIW, DTs first guess map has the LSV getting 2-4" and a significant ice storm on top of that I do agree with a lot of the posters in here in that it is tough going anywhere on this site and finding a forecast or model interpretation of the runs with a LSV focus. Even as the GFS just came out showing very cold surface temps and a big threat for ice I've not seen much commenting on it (this is for the Sunday storm) Link to comment Share on other sites More sharing options...

canderson Posted December 5, 2013 Share Posted December 5, 2013 My call for Friday for MDT: Rain, maybe a mix but it won't stick anywhere. Per models, LSV and N of DC/Baltimore is in for a significant, maybe catastrophic, ice storm Sunday into Monday. Please no. It gives Charlottesville nearly .9" zr!

sauss06 Posted December 5, 2013 Share Posted December 5, 2013 i just stumbled upon some notes of mine. December 15-16, 2007 we had freezing rain and lost power for over 7 hours. for whatever reason, i didn't document how much frzn we had. Link to comment Share on other sites More sharing options...
Atomixwx Posted December 5, 2013 Share Posted December 5, 2013 I was using #icestorm2013 in social media posts last week for fun. I guess I may have to bring it back out if the models verify on this one. Although I do think some see more snow this time than what we did last week.

PennMan Posted December 5, 2013 Author Share Posted December 5, 2013 i just stumbled upon some notes of mine. December 15-16, 2007 we had freezing rain and lost power for over 7 hours. for whatever reason, i didn't document how much frzn we had. At my parents' in Lebanon County 1.1" of rain fell with temperatures between 26 and 30 with that storm. They were without power for quite awhile. A big ice storm is not something I care to deal with, but all indications are that someone is getting one. Up here, the strong high sometimes means we hang on to sleet longer than anticipated, cutting down on freezing rain amounts. Link to comment Share on other sites More sharing options...

MAG5035 Posted December 5, 2013 Share Posted December 5, 2013 Euro appears to hold serve with storm #1. Was just looking at that via text data, pretty much about the same as last night. Thats a pretty sizeable snow event for AOO/UNV/IPT with MDT seeing a bit of snow at the tail end (about an inch). Guess will have to see if that ends up being the case or if the NAM and it's dysfunctional family pulls off the upset (That description of the SREFs was pretty much the best i've ever seen). GFS seemed like it was in between. Link to comment Share on other sites More sharing options...

December 15-16, 2007 we had freezing rain and lost power for over 7 hours. for whatever reason, i didn't document how much frzn we had. I remember this storm. We were flying out of PHL Dec. 15 to Texas. There was no WWA or WSW or any real mention of zr. Woke up at 5 a.m. to take the trash around and then leave and I stepped out on the sidewalk and busted my tail. We got in the car and didn't go over 15 all the way to the Turnpike only to find it completely closed. We had to take 30 all the way to PHL and never went over 20 on that drive. It was terrifying.

I'm guessing this is the best thread on here to discuss what's going on in Dauphin/York/Lebanon/Lancaster Counties? It is the best thread, indeed. As of now, models appear to show the more significant zr will be south of that route. I'm not a great source for reading models, but I think we get heavier rain up here which really helps decrease icing. As always, one of our awesome mets will be able to provide much more expertise. We are in NYC and driving home Sunday, we'll just leave earlier if we need to do so. Link to comment Share on other sites More sharing options...
