TSSN+ Posted January 20 Share Posted January 20 1 minute ago, psuhoffman said: It got the structure of the storm it just shifted 30-50 miles north at game time and every model missed that even the rgem which was right then went south with everything else lol. So I dunno how to grade that. I might be low because I’m measuring 6” but some of the early stuff might have compacted and it’s windy up on this ridge so that makes it hard. Ya I measured 7”. This is the biggest snowfall for me in the past like 5 years. 1 1 Link to comment Share on other sites More sharing options...
Roger Ramjet Posted January 20 Share Posted January 20 Looks like I will end up at slightly over 4". Worried about drifting on my access road tomorrow. Link to comment Share on other sites More sharing options...
psuhoffman Posted January 20 Share Posted January 20 There are reports of 8-9” in some isolates spots in south central PA. The 4-8” area ended up starting in extreme NW VA through northern MD border counties north into south central PA. Then the gradient south of that was severe. Those rgem runs we made fun of ended up pretty close actually unfortunately. These kinds of game time NW shifts with these boundary waves make up a large % of our areas busts. This isn’t that rare unfortunately. I always fear a north shift with these type storms. 2 1 Link to comment Share on other sites More sharing options...
Chris_B Posted January 20 Share Posted January 20 Well, 0.25” (rounding up) and 29.5° F in N Arlington near 7 Corners. Bust AF :-( Link to comment Share on other sites More sharing options...
Warm Nose Posted January 20 Share Posted January 20 RGEM yesterday. Honestly not too far off - the thermals wrecked things east of 15. 3 1 Link to comment Share on other sites More sharing options...
hstorm Posted January 20 Share Posted January 20 Right around 2 inches in Great Falls. Couldn’t get a good measurement because we went and spent the afternoon at Top Golf in Sterling. Awesome experience in the snow. This was a great storm here. A bit less snow than projected but the rates this afternoon were incredible. Nice to have a fresh layer of white for the incoming arctic blast. 1 Link to comment Share on other sites More sharing options...
Round Hill WX Posted January 20 Share Posted January 20 3.25” final in Round Hill. Congrats to the Nams and the Euro on the qpf front. The GFS needs a recalibration. 13.25” on the season. 2 Link to comment Share on other sites More sharing options...

I got 6.5" but measured on the sidewalk in 2 increments, 4.5 and 2. It's fluff so it'll be at 5" before morning if the winds don't blow it away. 3 Link to comment Share on other sites More sharing options...

I had warnings for 6” last year in two events and didn’t get over 3” in either event in Westminster. 1 1 Link to comment Share on other sites More sharing options...

MountainGeek Posted January 20 Share Posted January 20 Finished just under 6" - trees heavily loaded with the initial batch of wet snow and then topped with powder -- gorgeous out there. 2 Link to comment Share on other sites More sharing options...
dailylurker Posted January 20 Share Posted January 20 I just looked at my point and click. What happened to extreme cold. They raised temps by about 10 degrees over what it showed 2 days ago. Looks like a typical cold shot. Nothing record breaking. Models way overdue cold. Where's my -2. It's now 11. Wow lol 3 Link to comment Share on other sites More sharing options...

SomeguyfromTakomaPark Posted January 20 Share Posted January 20 Cool event, only about 0.5 maybe but we had 30-45 minutes of great conditions it looks wintry and it’s cold. Glad the northern folks cashed in. Really thought we’d get a few inches with this setup but the modeling was out to lunch with the QPF for us.

Paleocene Posted January 20 Share Posted January 20 Great storm up in Harrisburg. Probably 6" of fluffy big dendrites. Light, not accumulating stuff all morning til mid afternoon. Snowed hard from about 2pm-6pm. Excellent deform band stuff. Back to the snow hole tomorrow 9 Link to comment Share on other sites More sharing options...
PrinceFrederickWx Posted January 20 Share Posted January 20 0.4" for this storm, bringing the monthly total to 13.9". My target now is: 1) keeping the snowpack all month 2) clinching snowiest month ever IMBY (the record for that is 16.7" in January 2022). Let's keep the nickels-and-dimes going! 1 Link to comment Share on other sites More sharing options...
uncletim Posted January 20 Share Posted January 20 1 hour ago, NorthArlington101 said: Honestly I was mostly joking. This was a ~50mi shift from it being right. Remarkable consistency. Will still tar its reputation on this forum I imagine. Did it (Euro AI) ever “adjust”? Was it better than conventional Euro, say, 4 days out? Serious questions, not snark. Just wondering where it’s most useful. Link to comment Share on other sites More sharing options...
87storms Posted January 20 Share Posted January 20 Reports of 3" in downtown Frederick and 4.6" up the street from me a couple miles. Makes sense. I probably got 3.5-4". This one kinda made up for the January 6 situation. 1 Link to comment Share on other sites More sharing options...

Terpeast Posted January 20 Share Posted January 20 Looks like my forecast did alright for far NW burbs, busted pretty badly along i-95. Mby got close to low end of 3”, probably did reach that if I measured using a snowboard, but I just stuck a ruler on the sidewalk and again on my deck so I naturally got a more conservative number given all the compaction and melting. What went wrong? Simple. Cold air got delayed a few hours, while best frontgen banding was 30 miles NW of model outputs. Tough to get those mesoscale details right even 12-24 hours in advance, impossible beyond 24h. It didn’t impact places like Round Hill or Frederick much, but such a minor shift robbed us in the i-95 corridor. Unfortunate but it is what it is. Nrn folks, this one was yours. Enjoy! I know I did, too! 6 Link to comment Share on other sites More sharing options...
Amped Posted January 20 Share Posted January 20 Philly to Boston will do fine. Always the southern 100 miles of the snow swath that busts. Link to comment Share on other sites More sharing options...

Curious because it seems to me that weather modeling is one area where AI can be truly useful to society - possibly a major upgrade in modeling, which from my uneducated perspective seems to have stalled somewhat. But I also know we are only in the intitial stages of AI implementation. Link to comment Share on other sites More sharing options...
