    A fascinating graphic: some musings:

    1. The east has clearly been hit harder than the west.  This actually gives me a bit of hope.  Yeah there is nasty background warming but perhaps there really is a multidecade cycle that happens to be "favoring" eastern NA for warmth.  

    2. On the other hand, the eastern CONUS is on average lower in elevation than the west which suggests that it is less able to rely on elevation for cold and is this more dependent on cold air advection from the source regions.  So it makes sense that combined trends of warmer source region and increased pacific influence are hurting the east worse.

    3. Man 1998-2000 looks like it was an ugly period.

    Outside the come from behind victory in Jan 2000, there was no winter to be found in these parts. I was really young, but I remember basically getting out early all 3 years from a lack of snow days used. It was a rough stretch. Add in the March 2001 fail and dismal 2002 and you got yourself a 5 year stretch of rough winters. 2003 is when it broke, and it broke big. There’s been terrible streaks of futility throughout history in these parts. We’re on a cooler, that’s for sure. 

  2. I’ll add we had 1.67” of rain yesterday at our place. We missed most of it traveling back from Myrtle Beach, but we got clobbered once we got to the Capital Beltway with those elevated thunderstorms that rolled through. It was dumping rain

    According to NWS I’m in the 100+ inch zone at Donner. There is 3 extra bedrooms at this place…anybody wanna come and help me shovel lol 

    IMG_0054.png

    Should be good for 4-6ft up at that elevation. Enjoy the pasting! 

  4. Took a ride through the Catoctins today. Still 2-4” of snow OTG up around 1200’+ 

    Temp was 45° at my place and got down to 36-38° on top of the mountain. Whole different world up there. Really is beautiful

    *Missed a snow event in January. No reading so likely closer to 14.3-14.8” 

  6. Hate to say it, but kudos to the HRRR/RAP combo for sniffing this out basically since 14z runs. They are going to hit the nail on the head for here and basically hit the northern band in PA, to a degree. 
     

    Im not a HRRR disciple by any means, but it can be useful for trends in certain setups. It struggles with southern stream disturbances and does better with NS systems. I think convection within SS disturbances causes chaos in the model. Would be interesting to study. 
     

    My forecast earlier was terrible and I really forced what I showed everyone here. I didn’t have a good mental day today, so seeing it snow nicely helped bring up my spirit. Depression sucks, that’s all I have to say. 
     

    Have a good night everyone. Enjoy the snow, whatever falls. Truly a treat.

    Before the “hrrr great dryening” took over the conversation I was trying to advocate it the surface can just be cold enough rates and ratios could be really good based on the mid levels 

    Yeah. I think the 5” is pretty dead south of M/D except for maybe your hood, but 2-4” is still decent for those NW of US29. 7H fronto went into PA and that pretty much killed any chance at the max for here. Annoying, but it is what it is. This is still pretty nice to see.

    Rough snow forecast outline (Medium Confidence):

    Zone A: 6-10"

    Zone B: 3-5" w/ stripe of 5-6" within the 85H frontogen band that sets up from NoVA through SoMD. The potential does include the DC metro, but best chance for highest totals will lie on the edge and outside the beltway. Uncertainty for Southern DE due to thermals

    Zone C: 4-6" in the Catoctins and adjacent terrain 

    Zone D: 4-6" w/ max of 7" elevation areas above 650ft. This is tricky depending on 7H frontogenesis placement

    Most of region: 2-5" fairly widespread. Higher totals within the Parrs ridge area from NW MoCo through western HoCo into the Carroll/Frederick border (Clarksburg/Damascus/Mount Airy). 1-2" for areas south of Zone B

    I'll try to fine tune this forecast with the new 12z data set. Might be bumping totals a bit

    Perfect pass for us at h85 and the h7 fronto is off the charts. If the NAM verified verbatim, there would be 2-3"/hr rates happening somewhere and possibly TSSN+

    3k is a pounding too, funny how kuch is lower than 10:1, with those soundings and that setup, the growth should be great. 

    Colleague and I were just talking about this. Pivotal utilizes the surface as part of the formula for ratios on Kuchera and it's weighted too heavily. If it started off the surface from 925 and up, it would be much much better. The Kuchera ratios are better on WeatherBell, but still might be a touch high.

    Lol I remember that …. I think that was early in 2013.

    Was this the same storm someone said they didn't believe you had two inches of snow, so you took a picture with a newspaper with the date on it in the background of the ruler in the snow and a thumbs up? :lol:

    One of my favorite things I've ever seen on this forum.

    With the back-to-back January storms, the errors seemed like they were just sticking a ruler in a random spot and measuring snow depth. Now I'm even more stumped. The only thing we both know is that all the State Highway measurements are probably wrong again somehow. LOL

    There was just no way Ballanger Creek, who flipped over 30-45 min after me had close to 3” of snow, equal to places to my north. It’s maddening. I measured 2.25” to 2.4” basically everywhere. Not like the snow drifted. Maybe I missed SOME compaction with the snow at such low SLR, but Yeesh.

    As of 9:37 AM. That 0.6" 2 miles east of Leesburg checks out compared to mby. Should get a more complete set of obs by noon-ish.

    I call BS on the Ballanger Creek total. No way they got close to Thurmont or Emmitsburg. I’m north of them and didn’t even have that much. Dept of Highways has had some weird totals over this winter. Idk how they measure.
