Any way to confirm? I only have sfc, 925, 850, and 700...I don't know that anyone gets full soundings...at the risk of making everyone sad...here are 850 temps at 7 pm tomorrow. 2 Link to comment Share on other sites More sharing options...

osfan24 Posted December 16, 2020 Share Posted December 16, 2020 Nevermind, someone posted it above and yes, it's a massive step back. A low over Baltimore City ain't it, my friends. Are the GFS and Euro really going to be this far apart? Link to comment Share on other sites More sharing options...

Those maps are lol. They have be at 16” but when I check the temps at all levels I can only find about .4 qpf that’s snow even up here. To be honest, there has to come a time where you take a look at the consensus track for the LP center and the h5, steering, and the flow in a nowcast. That coupled together still makes it really hard to expect a low to go over Baltimore. Models seem to be struggling with the double barrel look and where the true MSLP is going to end up. As Wwxluvr said, this is a really sensitive set up, and I think that is reflected with regards to low positoning more than anything. The euro is showing some of the biggest "snow maps," but has the low the furthest west. That's after the NAM & GFS moved it SE @ 18z. I'm more focused on some of the short term indicators/mesoanalysis to see where our low pops and how the ML's react in response to that positioning.

They are awful. Which is bogus of course. But that also leaves the door open...one of the models has to be wrong with where they are putting the low, and there is signficiant discrepancy amongst Op's at the moment and even their ensembles. If the track of the GFS or even the NAM at 18z are correct but the euro has the thermal scheme correct, a lot of folks would be surprised at the outcome. The airmass is a lot more formidable than some have given it credit to this pt. Link to comment Share on other sites More sharing options...

psuhoffman Posted December 16, 2020 Share Posted December 16, 2020 Ok I think some are over analyzing a run where the low tracks OVER BALTIMORE!!!! Hopefully it’s wrong. But come on. If the low actually tracks from Richmond to Baltimore to Wilmington anyone from 81 east and south of York PA is screwed. We know that. This isn’t that complicated. Just hope that track is wrong. If you get the 12k NAM or GFS track with the euro storm presentation we get a big storm 95 NW. unfortunately the best guidance at this range we have looks like poo. No one mentioned both the RGEM and HRDRPS look awful and had their worst runs at 18z. I am rooting for the gfs but...it’s the GFS lol. Other then the GFS and 12k NAM everything else I saw continued to degrade at 18z. 1 Link to comment Share on other sites More sharing options...
