Interesting, the dam is actually on the north side of town but they're low elevation so maybe that explains the lower total? I'd say close to 2" where I am but not entirely sure because it flipped to rain way before I got home.

If you complained twice a year you could comment.

Yeah but you just complained though

what is? maybe forum melts, not sure you get more than 50" tbh. Hope you get 100" though - Today

That was quite the wintry 0z gfs run. days n days like ineedsnow mentioned. It's been showing up and hopefully comes to fruition. Also hoses NYC south so it's an added bonus! -
It's the moon.

29.8, I hope we get some snow Friday morning.

Saw this and thought "GFS is hallucinating again", now I can't get that map and "Lucy in the Sky with Diamonds" out of my head. Groovy. -
Last few GFS runs have been really neat. We're breaking the color chart. Yesterday's 00z gfs actually gave W Yellowstone 100" lol.

Our best chance to see some snow this month may be from a quick hitting Alberta Clipper or associated cold front. But of course we're talking light snow and nothing major. The trough is just too far east and the flow too flat. There isn't enough room or time for anything to really dig and slow down, gather moisture, and trigger a major winter storm as the maps look now. But it's early still and the models are not that good. Subtle adjustments and you just know they're going to happen could change things. We watch and wait. Most of my prior threat dates are now not so near misses. WX/PT

Nice looks like the call for a trimonthly of ~ -0.6 was a good call. Should continue to rise from here slowly. Unfortunately I do not think this will be an 'official' La Nina based on ONI numbers but darn close like last year. Still liking my call of about the week of Christmas into the new year being the warm up time frame leaving the tail end of phase 8 into 1. Here is an updated subsurface from beginning of October to December 1st. Also @donsutherland1 I'm still working on chatting with you about RONI. I may just create a different thread and tag you instead of keeping it in this one, we will see. Hope to be done by this weekend. Work and life just taking precedence right now unfortunately. -
Calm yourself Mr. Complainer, nobody said it is always right, plus is it Friday already?.
-
See? Euro ain't always right!

why can't we ever have every model it always has to flip flop around
-
Just brutal. I’m going to cry.

I’m seeing roughly 2-4” of new snow projected along the spine of the Greens through tomorrow with a bit more at elevation and a bit less in the lower valleys, but it looks like the snow starts tomorrow morning and lasts into tomorrow night. A quick scroll through the most recent run of the GFS shows 7 to 9 potential systems in the queue out through mid-month or so. A couple of them look a little warm, but the mountains will do their thing and get snow as long as there aren’t any heavily wound up systems passing to our west. That’s the beauty of a somewhat safe “zonal” flow. It’s not a textbook Northern Greens bread and butter pattern showing very discrete clippers lined up, but it’s certainly in that neighborhood and it looks like there are a lot of systems poised to come through. Now that we’re into December, average snowfall here in the valley is jumping up to 1 to 2 inches per day, and that means probably 2 inches per day for the local mountains, so that’s sort of the average baseline snowfall to think about. As it stands on the modeling, the GFS shows 2 to 3 feet of projected accumulation for the mountains at 10:1 SLR through the next couple of weeks, which would probably be about an average pace. That’s with the caveat of course that some of that projection is at long lead time and SLR ratios might be substantially higher than 10:1 depending on how much upslope snow is in the mix.

One last post before I call it a night. Something that I thought was a fun demonstration of how moistening the atmosphere truly works was this snapshot of the HRRR at 2am Friday. I really love how you can see the actual snowfall hitting the ground earliest along the spine of Shenandoah because the couple 1000 feet elevation they have compared to the surrounding areas means that there is less dry air between the clouds and the ground. It's fun to then see this reflected by it showing snow hitting the ground instead of sublimating. Dewpoint depression shows how the higher up you go the more moisture is making it to the surface as the lower values are found almost identically to an elevation map. None of this actually has a sensible impact on our weather or forecasts (though it does explain that the Shenandoah maximum in this storm is less the result of orthographic lift but instead this dry air quirk) but instead just a fun exercise to show how moistening the column works from the top down elevation wise. I will be sure to this run to show my mountain meteorology/climate near the ground professor as I feel that they'd appreciate it.
