Stinkbugspecialist Posted January 7, 2015 Share Posted January 7, 2015 Does it seem more amplified than yesterday's clipper. Or weaker ? Link to comment Share on other sites More sharing options...

No, that isn't what it says. It says the track is further north than the previous system, which is obvious...not that the models moved north.

RitualOfTheTrout Posted January 7, 2015 Share Posted January 7, 2015 Squall went through here a little while ago, probably the heaviest snow I've witnessed this season, to bad it was short lived. Link to comment Share on other sites More sharing options...
north pgh Posted January 7, 2015 Share Posted January 7, 2015 The Canadian is still insistent bringing the friday clipper further south. Something to watch I guess I saw this too and it gives us a nice little burst of snow. Now the Nam is south and wetter as well. We may be looking at another 1-2 inch snowfall early Friday morning. Not a big storm but it is trending better. I just had some really gusty winds go through. I am guessing with wind chills tonight most schools will delay tomorrow.

north pgh Posted January 7, 2015 Share Posted January 7, 2015 It looks like that squall line near I-80 has turned deadly. 3 killed and 30 injured. When we wish for extreme weather we often forget about the consequences. http://www.post-gazette.com/news/transportation/2015/01/07/14-vehicle-accident-on-I-80-near-Clarion-kills-at-least-one-person/stories/201501070185 Link to comment Share on other sites More sharing options...
CoraopolisWx Posted January 7, 2015 Share Posted January 7, 2015 That deadly accident not withstanding. From reading the NE Ohio thread, it was the dry air that really weakened the LES event region wide. Also the speed in which the ice began to form, didn't help much either.

Looking at the radar, it looks like the southern extent of snow is much further south than modeled. Hopefully we can get an inch or 2 out of it.

Rdd9108 Posted January 8, 2015 Author Share Posted January 8, 2015 An inch maybe. The only model on our side is the Canadian. Next week looks more promising for two different waves. Would love to post some maps but I gotta head to class and then the gym. Link to comment Share on other sites More sharing options...

Stinkbugspecialist Posted January 8, 2015 Share Posted January 8, 2015 Someone email the power plant and tell them to start churning around midnight tonight between the clipper and the plant snow maker. Maybee them two can phase and give a bigger snow totals.. Lol Link to comment Share on other sites More sharing options...

jwilson Posted January 9, 2015 Share Posted January 9, 2015 We'll have a stale air mass by Monday so it looks like a marginal event. I guess there's a chance for a serious ice storm, but I don't think anyone wants that. I'll take two feet of snow to an inch of ice anytime.
