Gfs really cut back on the primary to our west again. Almost coastalish now. Crazy

I think my yard gets sleet deform banded on the gfs. Lol. Waiting for sounding.

@WinterWxLuvr Look at the left hand side of the sounding. The bar graph shows omega/lift at various altitudes. The denritic growth zone (DGZ) is marked in red. Super short answer is you want the biggest bars between the red lines. On this sounding car alarms are going off and visibility is -.5 miles. Yes, it's a minus sign. You can only see what happened half a mile ago cuz it's atomic puking

Nobodys tossing mesos. They will get the warm nose more right than the globals. But we're still 48+ range. Mesos can magnify errors that far out. 24 hours from now is different

Ehoff has not only moved his own goalposts but doubled down on top of it.

Nam will prob be furthest north with mid level temp problems the whole way in. And it will prob get it right at game time. Burning question of course is how much wiggle room if any for snow. Beats me. Like 0z so far tho

We'd all be better off just acknowledging that the nam took a couple tabs of acid earlier, is now coming down off the trip, and not analyzing anything beyond that.

I guess it really might be possible that the nam was way off the rails and is crawling towards where every single other reliable and unreliable model already is. Didnt see that coming

Def wait at least until tomorrow eve if possible but if I were in your shoes I'd grab a wed flight if we're still looking at the same thing the euro/gfs are spitting out. Even if snow fails, if it's still looking like rain with temps in the 20s @ IAD thurs the risk of sig delays and/or cancellations is pretty high. The is the first one of these waves to hit with temps being below freezing for 24+ hours straight before it starts

It's obvious man. With all the posting about the other 3-4 threats on the way, it's really confusing figuring out which one people are talking about.

We should just go ahead and do it now before 0z. If 0z fails we can immediately delete the thread to save the storm by 6z.

Only once the most important model caves... aka nam

6-8 is my goalpost There is no way you get that much rain and sleet.

Nam wins again lol Hmmm... euro looks like nam? You need to post an explantion why on your wx page so I can make the connection. No matter how hard I squint and go cross eyed, it still looks like the gfs and para

Euro looks great to me. Mids are still trending the right way. Perfect. As heights press, slower onset often comes with the territory. That's 2 steps in front of what I'm watching. Heights are prob going to start sliding the other way sometime between now and wed night. I like where this is a lot more than I did 48 hours ago

Be careful dude. You might get Short Pump'd tonight. Shelter in place. Hopefully with a perfectly cured nug of Gelato Cake

That's most likely a factor of the colder/more confluent flow run over run change. That acts as a better defense against the bull rush with precip/warm air so it shouldnt be a surprise. Models are prob too juicy as they have been at this range quite often. However, at 72hr leads, having things shunt souther/colder could not be more welcome for our area. At least to me anyways. Warm fail crew shift will prob get replaced by suppression fail crew shift here shortly if this continues. I'm an entrepreneur and my own boss so my crew likes where my yard is.

Para should be interesting given that its dad upped the cold game

Gfs looks better across the board with heights/temps etc leading into onset. Still got that trend going in our favor.

Here's where I think the disconnect between you and leesburg today is rooted. A few short days ago this was an abject failure and barely discussion worthy. Globals quickly and unexpectedly set the hook with arguably too bullish of snow solutions with front end. It's fun to consider but I think everyone knows high end results are full of peril. Plenty of people have said as much. But when the nam did what it did at 12z, you drilled down to the subatomic level of why it might be right and why we should seriously worry. Well, we're all appropriately worried already imo and just having some fun. But man PSU, you really sunk the nail this AM with nam analysis. And now with my quoted post it's either high end results or bust. And that's totally fine and you have every damn right on earth and venus to feel such a way. Just don't expect us all to feel the same away about it. It does have the feel that your goal may be that. Maybe I'm out to lunch and I probably am but my read of the room comes to that conclusion.

Icon actually tic'd colder at onset. Screw the NAM

This is just my rule of thumb and anecdotal. When meso's have 2 events in their range to deal with, it's always best to wait until the first one is out of the picture before fretting solutions that are vastly different than the globals beyond that. The whole time/compounding error thing can often go haywire with mesos. Also, meso's biggest value is short range and not mid. Still a day or more away from being in the short range. Not saying the NAM wont nail it. Just that if you're trying to actually forcast and not weenie out, a blend of guidance and much less weight on outliers helps keep your job

100 miles? Pffft. That's less than 1 NAM run away to correct. 1000 miles is a red flag tho

Which in itself is fine and why Ji is Ji and also why I like the guy. The problem here is he's very contagious and the only vaccine is snow. Basically I'm saying there is no cure

Typical dead guy response
