I just watched Joe Bs daily video and he says its gonna get darn cold again and there are gonna be some good widespread storm threats. He says the pattern is something to behold especially in march.

 

53.9" for the season now for KPIT. Probably a realistic shot at 75" total by end of March.

Where are you at? The highest official report for that storm from NWS Pit was 26" i think in southern Allegheny, and 21.1" at the airport. That fell in about a 16 to 18 hour period. The rates we were tracking that night generally peaked at 2" to 2.5" per hour. (Which was spectacular!)

But...

The Jan '94 had documented 5" per hour rates for a short time. Those were downtown and points south and east. That storm had a very under represented 14" at the airport, but 20" downtown. There was up to 30" south and east

The March '93 storm had several 3" per hour hours both at the airport and other places. That sett the a time 24 hr snowfall amount at 23.6" Obviously, that was another level in terms of 50 mph winds and 36" totals to the east.

Feb 2003 was a more drawm out storm with out the pounding rates. The area got 15" to 20" more on duration i think

I'm not saying feb 2010 wasnt a great storm. It was. However there were a few other recent ones with heavier per hour rates.

This is the hourly obs for peak of the March 1993 storm:

12 PM EST HVY SNOW  23   23  100  N18G31  29.45F  VSB1/16 WCI -4 1 PM EST HVY SNOW  23   23  100  N17G25  29.39F  VSB1/16 WCI -3  MIN TEMP LAST 24 HRS 22  PRECIP LAST 6 HRS .10                             2 PM EST HVY SNOW  22   21   96  N23     29.28F  VSB1/16 WCI -10 3 PM EST HVY SNOW  21   21  100  N23     29.22F  VSB1/16 WCI -11 4 PM EST HVY SNOW  20   18   92  N28G40  29.20F  VSB1/16 WCI -16 5 PM EST HVY SNOW  18   17   96  N25G39  29.19F  VSB1/16 WCI -17 6 PM EST HVY SNOW  18   17   96  N25G37  29.19S  VSB1/16 WCI -17 7 PM EST HVY SNOW  18   16   92  N28G36  29.19S  VSB1/16 WCI -19

1/16 mile visibility? Yeah, that's 3" an hour, even with wind. Plus, there are plenty of references to 3" an hour rates for that storm. I lived on Mt Washington during that storm and I measured a 4" rate from 3 to 4 pm.

That would be a site to see. I hope I can see rates here like that again soon, although I know thats more likely around the coast or lake effect.

I saw March 12 21993 was one of the analogs showing up for the upcoming pattern. Just sayin. ;)

 

00z NAM still looks pretty interesting for tomorrow night / Tuesday morning.

Don't you dare screw with me. That would cause endless model watching during the week. It was nice getting drunk and not staring at models. Weekends ftw.

gfs is looking pretty nice for tomorrow now as well. Mixing doesn't seem to be an issue. A general 3-5 with 4-8 just to the north. 

 

I think it's going to be an issue in the beginning, especially for the communities south of Pittsburgh, but I think overall it'll be mostly snow for everyone, especially when the low gets closer.

Looks like a non-event down here tonight (maybe a couple inches), at least according to the NWS forecast.  I haven't really looked at the models.  Last of the snow for at least a week, which would essentially tie the longest we've gone this winter without a snow threat.  Pretty incredible how this entire winter has been a train of storms.

 

The snowpack may actually be gone after this weekend; I haven't seen grass in quite a while.

Weather Tidbit for the night: Yesterday's snowfall at the NWS office measured 2.5" out of 0.02" of liquid equivalent. You may have seen us refer to snow-to-liquid ratios or snow ratios in products such as our discussions. A "normal" snow ratio in Pittsburgh would be around 12 to 1. Today's snow ratio worked out to be 125 to 1! That's an absolutely stunning number.

that isn't even a fight 

 

I'll keep a tally, but for now it appears the RGEM is standing on its own.  The NAM says just 1-2 down here, so it would agree with the NWS.  The GFS appears to give us a little of everything which would cut on max snowfall.  I don't know where to access the accumulated snowfall maps for the latest GFS, though.  Euro I haven't seen.

RGEM has been a great model for Precip type over the last 2 Winters that I have been following. They keep the snow line all the way to the PA/WV border. I think Morgantown is on the line but most of Greater Pit will see all snow.
