Euro continuing it's weekend trolling on a more amplfied system. Snow to wintry mix event for AOO/UNV, all snow for IPT, MDT looks to be mostly rain. GFS keeps most stuff with this system south for now, and thats not a bad thing at this range haha. I seriously would keep an eye out on this system, especially our more northern folks.. as there may be just enough cold left before it gets run out in the wake of this one. Could be one of those classic finally see the snow but it melts the next day type deals.

EDIT: I didn't realize i was still viewing the Pitt thread when I posted this haha. Euro storm for the weekend looks to be primarily a rain event for the Pit area.

Its 53 out and I'm getting sleet mixing in with the rain where I'm at. Not hail, but little sleet pellets. Interesting.

The temp was 52 and the dewpoint was 45 at KAGC at 1pm today....the 850 mb temp at 12Z was +6 C.....I can fathom no way that you were seeing frozen precip. I'm very curious what you were seeing...but I really have no explaination without seeing it myself.

Batten down the hatches....the front over the next hour means business....gusts have been in the 50-60mph across all of eastern Ohio.

A few flurries overnight...with wet surfaces freezing, if the wind doesn't dry everything off.

Believe me, I thought it was odd too, but that's what I saw. Not making it up. When I was sitting in my truck eating lunch today, I was watching them bounce off of my windshield and hood. You can tell when sleet hits your vehicle because it makes a louder sound than a raindrop. It didn't last long. I should have tried to take a picture of it, although I don't know how it would have turned out on my camera phone. Strange indeed for that warm of a surface temp. Can't explain it. Maybe put it in the same category as a UFO sighting then. :D

Well condsidering it's coming from you and not Therusselwxman or some of our more notorious posters, thats why I'm trying to think of a plausible explination. :D

With that high dewpoint/relatively saturated surface enviroment....and I checked this am's sounding (12Z)....the freezing level was about 7500 ft....and it may have been higher at 1pm. The precipitation was general stratiform in the afternoon, so that rules out hail...the convective showers didn't hit until the front this evening....oh well...to the little part of met that is left in me, it's driving me nuts trying to figure this out.

I don't know. Maybe it's possible that it was so windy at the time it was just rain hitting my truck hard and bouncing off like sleet would. I'll just go with that explanation and move on. :D

No offense, but I was trying to scientifically figure it out, because it makes no sense. I think I'm better off not posting....so I think that's what I'll do from now on...just sit back and read...enjoy your wx.

Nah....we need the more educated, scientific stuff around here too. We are traditionally a bit starved for it, relatively speaking.

Can't believe it's Jan 18th already. The below average snow had to happen sooner or later....but I would at least like a couple nice events to track.

By all means, post. I welcome your explanation or anyone else's. I don't think anywhere in my posts I was suggesting that you shouldn't. Believe me, I found it weird too. It's possible I could've just been seeing something that wasn't there. Wouldn't be the first time with my great eyesight. :D Wasn't trying to offend you or suggest anything with my last post. I'm not quite sure how or why you took it that way. I was basically joking around about it in my previous post, that's all.

GFS and NAM both look like a maybe 1-2 inch possibly even 2-3 inches overnight Thursday into Friday. GFS is colder for Saturday which would imply more of a mix, while the NAM looks like mainly rain with maybe some brief frza to start. Hopefully things don't trend towards a more icey outcome for Saturday but the potential is there for at least some.

Yeah, there's a pretty big difference in temperatures between the two models for Saturday. I don't want the GFS solution at this point, because I think it would mean a possibility of ice like you mentioned. I'll take plain old rain over ice any day. It'll be interesting to see which one of the two ends up budging on this as we get closer, or maybe we end up somewhere in the middle of the two and still get mostly rain Saturday.

Sorry BlackN'GoldRules....my identity is in my member title....CoraopolisWx got it right....I just need to take a break...I'm a burned out met that is looking for a career change and taking it out on this forum is not the right thing to do. I have mostly lost my passion for wx.....but everynow and then I get pulled back in. I need to come back when I'm in a much better situation and state of mind. I'm not into board drama and sorry if I was a cause of some here. I do apologize.

No problem.

I remember your posts in the past. Very informative.

We don't get to much met experience in this Pittsburgh thread and I am just a weather nut like most others looking for more information and discussion.

Don't be a stranger however we need more storms to get more to discuss.

It's OK man, don't worry about it. Hope things work out for you in your search for a different career. Believe me, I know what it's like to be burned out doing what I do for a living. It can take a lot out of you. Anyway, no hard feelings. Post some more of your thoughts and ideas here in the future when weather becomes an enjoyable hobby to you again. We'll always welcome an expert's ideas here.

18z GFS is a little warmer than the 12z solution, but still gives us a decent amount of frozen precip at the onset. 18z NAM basically almost makes this an all rain event. Maybe just a very brief period of frozen precip at the start according to the NAM. Of course, these are just the 18z maps. We'll see what the 0z will show. I have to work very early Saturday morning, so I really don't want to see any ice out of this.

0z GFS keeps us all frozen on Saturday. 0z NAM is a little colder than previous runs but still mostly rain.

GFS trending our way.

We need the 12Z NAM to come in a little colder and the GFS to hold serve.

I would like some snow. No ice please. Would especially be nice for a Friday night and Saturday with no work.

I have to work early Saturday so I'm really hoping for no ice. Looking at the GFS keeping us frozen, and the position of the low, freezing rain is a definite possibilty according to the GFS run.

12Z NAM still looks good for about 2-3 inches of snow starting this afternoon. (1pm) Ratios are pretty high during the bulk (nearly 20:1) so it should be a fluffly snow.

For Saturday morning NAM still warmer, looks to have the system further north so we get some zr over night but should be plain rain by 6am if the NAM is to be believed. I have to be out early Saturday, so I am hoping for either rain or snow, nothing in between lol.

As per today's 12z RGEM, anyone living north of I-70 stays frozen throughout the event. Would probably be a problem for bridge traffic in the metro area.

Just from past experience, the warm air always seems to be underdone for the SW portion. Ive seen it a 100 times when we are forcaseted to get snow, and it ends up being sleet or just plain rain. Once you make it into Butler and Armstrong counties though the cold seems to hold on a bit more. This system may be different though in that it is not a really woundup and it just a wave moving east to west essentially.

Still haven't seen a flake of snow in Greensburg yet for todays event.

So true....except with the strength (or lack thereof) this this system, I'm not sure if there will be as much warm air advecting in.

Starting to flurry in town
