Big changes on the 00z GFS run for the weekend storm. Not for the good unfortunately. Hopefully, just one run and won't turn into a trend. Let's see what the 00z Euro has to say about this.

Yeah I saw that, seems like all models lost the storm to some degree. I guess there is that saying that models tend to lose the storm at some point, hopefully we are just in that period.

 

Now this is just pure conjecture, but I've always wondered when all models tend to lose a storm at once if it has something to do with data sampling. IE, lets say some critical part of the storm that was modeled to exist all of the sudden finds itself in some sparse region that doesn't get sampled well, that then causes the solutions to be way off (hence the models lost the storm), then once this feature moves back into better sampling the storm re-emerges. On the other hand, it could just be that as we get closer in time and things are better resolved its now been determined the storm won't happen, I guess time will tell the tale.

Thinking North of 422 is going to be the place to be. Still think that rain line goes farther north. Maybe to I-70?

 

I live 1 mile south of 422.  

It amazes me how it truly is a dividing line with the weather.  It could be flurries in Ford City and as soon as you go across the bridge into Kittanning, BAM....a blizzard.

I'm pretty close to you any thoughts on Indiana? Nam really brings in warm air.

I doubt we see all that much snow, but this mostly rain stuff that is being said is simply not true.

You better hope we see rain or snow. With the short salt supply Ice would be horrible.

I just think that low is going to push warm air further North. I'll admit I haven't had time to dissect models, but knowing our history on this type of event we torch (at least city and south) more times then not.
