psuhoffman Posted February 16 Share Posted February 16 26 minutes ago, Stormchaserchuck1 said: Even the global models do not have more than 2-4".. I guess the radar is more impressive than that? 3 things. 1)Often these last second dry trends on guidance are BS. It’s happened many many many times. I can think of two that really stuck out. Last run before Jan 2004 storm after days of 4-8” guidance suddenly came in dry with like 2-4”. We got 4-8. Night before Feb 11 2010 guidance slashed qpf way down. We got what they had been showing. I don’t know why it happens. But many times I’ve observed this dry up right at game time and it was wrong. 2)Radar looks great and the forcing over the area is insane 3)they might be counting on better ratios than models think. The DGZ is perfect. It’s only ground temps. If it snows hard enough to overcome ground temps ratios could end up better than the 8 or 9-1 the models are thinking. 6 minutes ago, MN Transplant said: They suck, but trend is trend I don’t know what to make of it. The radar looks in line with the NAM/GFS/Euro with a healthy southern precip max along the polar boundary not focusing on the arctic boundary. But the CAMs keep going harder and harder on the arctic wave and drying up the fgen associated banding which makes little sense given how intense that looks. Of course to make it worse I can’t find an outlet that shows mid level dynamics for the hhhr or rap so I have no way of knowing why they are doing that. I can’t tell much just from the crap data they provide for those. 7 1 1 Link to comment Share on other sites More sharing options...

If it snows hard enough to overcome ground temps ratios could end up better than the 8 or 9-1 the models are thinking. 2 things. 1) They aren't really drying up right now. They haven't showed more than 4" across the area for the event the whole way along.. It's only suppose to snow moderately for 3-4 hours. that's why I'm like, why is the NWS predicting 5-8"? The radar and ground elements must be awesome. 2) Last storm they dried up last minute, and it verified. I know in the higher elevations you had like 6", but where I am I went from 4-6" on models to 1-2", and ended up with a dusting.. the whole area less than 500-1000ft experienced the same thing. That's why in these marginal temp situations the 1:10 Kuchera maps are especially wrong.. the snow fell very wet and light because warmer temps went into some upper levels of the atmosphere. I'm at 39F and it will probably drop down to 31-33, but for 10:1 results you usually need to be in the 20s. 2 Link to comment Share on other sites More sharing options...

Terpeast Posted February 17 Share Posted February 17 Maybe I was right to call out the north trend yesterday. Hopefully the good radar out west means still good qpf totals on the southern edge (which I hate to be in) Link to comment Share on other sites More sharing options...
Miss Pixee Posted February 17 Share Posted February 17 2 hours ago, EHoffman said: "High elevation" being a relative term...but yeah people forget upper NW is quite hilly. If you go to Fort Reno Park they have a little placeholder for the highest elevation point in dc. It's...underwhelming. Because with elevation you need sight lines and flat land flat to compare it to. It would be like living on the upper level of a building with no staircase or windows, there's no reference point.

Remember that rug pull like March 8 2018. Euro, NAM both, GFS, RGEM GGEM all had 4-8” across MD from that miller b? Then the HRRR started showing nothing…with the precip shield developing like 75 miles northeast if what all other guidance had. I remember us both saying to each other, We’ll die on the hill with the euro et all. No way all guidance is that wrong from like 12 hours and hrrr is right. Well… still waiting for my 4-8” from that one. Not saying I buy the hrrr and rap. We could cite 100 other times they were off on a crazy tangent. But I never ever feel comfortable unless we’re in the bullseye of some hecs with 20” 75 miles either side of me heading into it. It’s slightly troubling and perplexing they are trending worse as we get closer. People like to pretend it’s safe as some coping mechanism but I’ve had enough rug pulls and I guess I’m not a cops by lying to myself type. 4 Link to comment Share on other sites More sharing options...

NorthArlington101 Posted February 17 Share Posted February 17 Why not just a total precip map?I don’t know, but I checked after and I swear it’s all of it. Storm runs through in like 3 hours.
