Could be some brief 0.1-0.2 mile visibility on the roads. Yeah I feel like its overdone but let's just see what the hi rez models do now because the global's are useless at this range. I would love for those rates to verify. We don't usually get to see those kind of rates so even as progress as this system is it would atleast be interesting.

MAG5035 Posted February 6, 2020 Share Posted February 6, 2020 It's not the most ideal scenario by any means, but the inside track this low is supposed to take through eastern PA should be sufficient enough to keep the Pittsburgh area in some decent precip for a bit after the changeover. I think Pittsburgh metro should manage at least a couple inches but I do believe the best snowfall may reside in a line just east running up the Laurels thru Indiana/Punxy on up into Northern PA. Higher areas around the metro probably do a bit better accumulation wise but the cold air coming in with the developing low moving from VA into eastern PA should provide a pretty clean changeover for everyone. That HRDPS can be a bit too wound up with it's precip rates but the dynamics present offer the opportunity for a period of decent snowfall rates. Placement/coverage of the eventual precip area generated from the deepening low and the track of said low will have to be watched closely to see if this under or overachieves. Both options are on the table in western PA. 5 Link to comment Share on other sites More sharing options...

I hope somebody overachieves... I have a different set of problems to contend with over on this side of the Laurels with this one. Right now I think KPIT at 12.7" is going to keep its lead over the 10.8" I have to date. I only need about 40" more to get to average for the season lol. 1 Link to comment Share on other sites More sharing options...

jwilson Posted February 7, 2020 Share Posted February 7, 2020 SREF plumes are up to a mean of over 4" now, compared to 2.5" earlier. Meanwhile, the HRDPS is a pretty good hit for us (6-10"), though the model name always makes me think it's derpy. Not sure it's all that valuable, just another possible solution.

KPITSnow Posted February 7, 2020 Share Posted February 7, 2020 0z HRRR dropping. 1-2 inches over pittsburgh...every direction 50 miles from us 2-4 inches. Can’t make this up. Link to comment Share on other sites More sharing options...

MikeB_01 Posted February 7, 2020 Share Posted February 7, 2020 Sorry I am a little late to the party.. Should at the very least be a fun one tonight. Still waiting on the 21z SREFs, but the 15z kicked out 4in and about a 50% chance of 1"/hr rates around 7am. Id take that in a heartbeat. 1 Link to comment Share on other sites More sharing options...

MikeB_01 Posted February 7, 2020 Share Posted February 7, 2020 That interesting hole in the HRRR that seems to be right over our area has to be an error. I think the snow totals are a little low because there seems to be a struggle to be transition 100% over to snow. The PType map is showing freezing rain still in the area around 10z. However, looking at the sounding, I don't think FZR is falling during that time. Not sure what the HRRR is finding right there. Link to comment Share on other sites More sharing options...

That's the nice thing about the HRRR, if you don't like what you see just wait an hour. Really, that band is pretty narrow, and looks like it wants to setup right over or just to the east of Allegheny county. That small of a margin of error is going to be hard for models to nail down.

KPITSnow Posted February 7, 2020 Share Posted February 7, 2020 I think regardless tomorrow morning’s commute will be a nightmare. Obviously not the same setup but there was a storm last year we got 3 or 4 inches, but it came at like an inch an hour rated starting at 5 am? Was a total mess. I’ll probably delay heading to work if it all goes to hell. Link to comment Share on other sites More sharing options...

jwilson Posted February 7, 2020 Share Posted February 7, 2020 Changeover occurred between 330 and 4 AM. Have what looks to be an inch or so thus far, boundary might be setting up east, but the snow side of this system looks more robust (for now) than expected. We'll see when bombogensis occurs how frontogenic forcing interplays with the current shield. Link to comment Share on other sites More sharing options...
