chris87 Posted October 27, 2011 Share Posted October 27, 2011 Rain to snow at 48 on 18z GFS? Could be a bit earlier... looks that way...between 45 and 48 950/925 hpa goes below 0... Link to comment Share on other sites More sharing options...
Wonderdog Posted October 27, 2011 Share Posted October 27, 2011 I know that we got hit back in the late 70's or early 80's with the Veterans day snowstorm. Does this potential storm mirror the Veterans day storm in any way? Link to comment Share on other sites More sharing options...
Amped Posted October 27, 2011 Share Posted October 27, 2011 Amped and Juiced, Just how I like it. I'm going by the 540dm line for rain snow. Forget my earlier post I believe most areas will see some snow falling out of the sky. Accumulation is another story. If the storm moves offshore in a more easterly direction we have a better shot at wraparound and more areas may see accumulation. The time of day may make it rough though.

TUweathermanDD Posted October 27, 2011 Share Posted October 27, 2011 From what I'm seeing, a decent amount of the precip is snow for DC/BAL if it switches around hr 45 as we get precip out to around 51/54. Yoda that call seems about right. Link to comment Share on other sites More sharing options...
yoda Posted October 27, 2011 Share Posted October 27, 2011 looks that way...between 45 and 48 950/925 hpa goes below 0... It did to me as well.. just wanted to be sure someone else saw what I saw too Link to comment Share on other sites More sharing options...
yoda Posted October 27, 2011 Share Posted October 27, 2011 Take with gain of salt... but yes, that says 3" I-95 N and W... 6" out towards BR/Shenandoah/Catocin Link to comment Share on other sites More sharing options...
usedtobe Posted October 27, 2011 Share Posted October 27, 2011 looks that way...between 45 and 48 950/925 hpa goes below 0... [/quote To me it looks slightly warmer initially than the 12Z GFS. Still pretty similar but nothing like the NAM in terms of temps or total precip. Link to comment Share on other sites More sharing options...

Yoda that call seems about right. The soundings didn't show snow until around 15Z in Leesburg. Dc would not be snow until closer to 18Z. Link to comment Share on other sites More sharing options...

Ian Posted October 27, 2011 Share Posted October 27, 2011 dude why even post that? if nothing else people should at least read back to see maps that have already been posted. we need to be a little more careful when there are 100+ in a thread not to have it fly 400 miles an hour.

BethesdaWX Posted October 27, 2011 Share Posted October 27, 2011 Yeah but it seems like 1 out every 4 posts has a clown map on it. Even worse the posts get all sqished together when there are tons of photos which makes it even more annoying. Maybe I'm overreacting, sorry.

My apologies, figured prefacing it with "clown map ftw" made it obvious I wasn't taking this seriously. It's October, its ~60 degrees outside, and a computer model has us getting a foot of snow. Of course it won't happen, and probably nothing even remotely close to it will. But it's still... unusual. That's all. Link to comment Share on other sites More sharing options...
snowfan Posted October 27, 2011 Share Posted October 27, 2011 You want to see panic.....let those totals happen. Pepco and BGE would be screwed. We'd all be without power for 1-2 weeks.

WxUSAF Posted October 27, 2011 Share Posted October 27, 2011 Those clown maps use 10:1 ratios I believe. As Ian mentioned, you'd be looking at more like 5-7:1 with the expected thermal profile. PSU Hoffman storm last year had 6:1 ratios. Link to comment Share on other sites More sharing options...

PSU Hoffman storm last year had 6:1 ratios. Do all free ones do that or are there any that have other variables? I saw one from StormVista that was considerably lower if not half lower (8" max stripe running up just east/west of DC). I suppose I'm not necessarily a fan of those maps in the heart of Jan/Feb anyway though! But we have certainly seen a lot of them in this thread...

Before this thread runs out and we go to Ian Disaster 2: what is the policy on model run threads ? It used to be a tradition of these boards. Is it frowned on now with the growth of the group ? I think if you have a model thread when we have something to track, you can contain all most of the images in one place. Link to comment Share on other sites More sharing options...
WxUSAF Posted October 27, 2011 Share Posted October 27, 2011 That one dropped 14 inches here. Yeah, and there was about 2" of liquid equivalent. Do all free ones do that or are there any that have other variables? I saw one from StormVista that was considerably lower if not half lower (8" max stripe running up just east/west of DC). I suppose I'm not necessarily a fan of those maps in the heart of Jan/Feb anyway though! But we have certainly seen a lot of them in this thread... Maybe some are more sophisticated than others. But from what I've seen, they're usually pretty close to 10:1. As you know, snow accumulation is such a fickle thing, even more so with marginal conditions like this. Any sort of clown map has value only marginally above entertainment. Link to comment Share on other sites More sharing options...
Ian Posted October 27, 2011 Share Posted October 27, 2011 Man, no love from HPC for northern Md. counties. It is kind of an odd line right on the border tho the experimental has a similar (if a bit north) gradient. http://www.hpc.ncep.noaa.gov/pwpf_24hr/wwd_24hr_probs_sn.php Link to comment Share on other sites More sharing options...

This storm sorta creeped up early of course. I think a model thread separate from a forecasting/tracking/obs type thread would be great personally. Sometimes you want one or the other and not a giant mishmash. We're still too wedded to superthreads... Link to comment Share on other sites More sharing options...
