Yup... more amplified wave, further south

Look at the 24 hour change!

Just like everything else its trending the right way. It's subtle 6 hour run to run...but if you go back and compare these runs to 24 hours ago its significant.

I've had a few meetings and in between tried to enjoy the snow with the kids so not been all over every model as it comes in...but just looking at where we are now v 24 hours ago things have moved the way we want in every way. There is more interaction with the trailing wave which is amplifying the trough more, and the track of the wave has shifted south some. If we continue these two trends we might back our way into another moderate event!

Got a little over 4". Was out with the kids this morning. Nice event. Sucks the coastal part kinda crapped out after most guidance teased us with it yesterday. The axis of my snow map turned out pretty good but I was about 1-2" too low with the zones. I would have bumped my 2-4 area up to 3-6 and my 1-3 up to 2-4 yesterday if I bothered.

I had stuff to do. 3.5” 24* coming down pretty good right now. Maybe I can make a run at 5”

People get wxbell for the access to models and graphics. If he pulls in a niche audience he cultivates it’s a bonus.

@Ji @jayyy something to consider wrt JB. He isn’t as bad further north where it actually snows more. He still hypes and is playing to that audience imo, but his issues are made worse by the fact he doesn’t know jack about our snow climo and I know that for a fact from our old communications in the 2000s. He judges the whole mid Atlantic area south of PA by DCAs numbers. He thinks if I get 20” it’s a snowy winter! Keep that in mind when he predicts above normal snow down here. To him that’s just 15”!

Gentlemen…

I let it know

It’s not doing much up here yet. And I actually like to analyze and chase.

The NAM when it actually has the synoptic level stuff right and isn’t off on a tangent resolves the meso details best of any guidance. The program is it’s off on a tangent every other run and it’s hard to tell when breasted it isn’t consistent in how it goes crazy. It can have feedback issues and suppress a storm. Or be way over amplified. It adds confusion imo. Frankly all the meso models do imo. I used to try to use them and it burned me so often I stopped. Now I basically use a blend of the globals and my gut instinct then at short range apply common sense to get the meso details. I’ll look at the high res models to get an idea what the details might look like but then I apply that to the Synoptics of the globals. It’s been working for me. Maybe someday they will develop a meso model that isn’t prone to wild tangents.

Thank you so much I didn’t realize my mistake.

A blind squirrel…he goes with the long shot how could the models be wrong and it shows snow EVERY time. The thing is he probably isn’t wrong about HOW it could happen. It’s just that he predicts that long shot it’s gonna snow when no model has it scenario every damn time! He actually does the complete opposite of me. I know out shitty ass climo so whenever guidance shows snow I look for how it could fall apart. And like 90% that’s what happens! When I struggle to find a realistic way it can go to crap that’s when I feel confident. He looks at every scenario and says “how could it possibly snow” and goes with that. He will be right every time it snows. And wrong every time there was any slight chance at day 10 and it doesn’t. That simple. Unfortunately my method is accurate WAY more often.

They obviously made a typo. The date is wrong. That’s the forecast for Jan 20 2034.

Nevermind, I must be wrong

The good news is if you look at the mid and upper levels...we are in what would be the comma head and deform zone IF the low actually amplifies closer to the coast. This was a MUCH better setup for us to get a snowstorm than last nights runs. Problem was the initial wave kinda ran off and the phase was sloppy AF and it never came together...but we were in the perfect location to get into it had the storm phased cleaner. A lot of runs recently...even if it all came together we were going to be too far SW based on the mid and upper level progression. I liked this run a lot better for our prospects.

yes...BTW I uploaded the wrong image and just fixed it LOL. The one I originally put was from Feb 2016. Ironically they look very similar which is why I didn't catch it right away. Which is funny because I've always held we underperformed in 2016 and that period in Feb is one reason why...but there was a perfect track rainstorm in Feb 2016, I got about 9" up here, and I think that was the one I posted first.

The main SW is digging more...that is the MOST important thing IMO. It's a sloppy phase with the STJ and the lead wave runs off and its a mess and never recovers...but we can work on all that so long as we have more dig from the main SW. Without that nothing else matters. The thing is DOA. This solution while underwhelming leaves open the possibility for a better result. Yesterday it was heading the wrong way in that regard.

NAO was negative... people at the time called it "thread the needle" but the pattern was pretty good...just the thermals were marginal and "iffy" by those days standards anyways lol. Perfect track and amplification overcame the marginal temps. Then everyone complained when it melted right after because again...the airmass wasnt cold.

For the record I actually tend to think the lack of a HECS after Presidents Day to about March 15 is just simple random luck. Truth is HECS are pretty rare. We haven't had many in January since 1980 either! Just 1996 and 2016! There is way too small a sample size. If you track smaller snowstorms like 6" plus it's clear our climo degrades QUICK when you hit March 10-20 depending on where in the region you are. But I think the last week of Feb and the first week of March if the right setup comes along it would not be too late to get a HECS. The end of our winter climo has been affected way less than the beginning due to SST's cooling by then.

If you go back to the 60's we do, since then not so much...the question is was that just random or...you know. Are we "due" or...

UKMET is mostly a 1-2" event Friday...but its a beautiful SW pass and the bullseye axis is right across DC. Getting this to track south enough is my main concern at this stage...we can work on beefing up qpf and a little more amp on the coastal later. Nothing matters if the wave goes north of us though and they never come back from that...almost never.

There was always disagreement for early Feb but all guidance agrees the NAO goes negative again by mid Feb. The Euro had a -NAO early Feb but it was always a very weak signal...it didn't go strongly neg until later...now guidance is more in agreement that the NAO starts to flip back negative between Feb 10-15. That's fine with me...Feb 15-March 10 is still prime snow climo. And there would be opportunities for snow before then in the advertised pattern. JUst not really a HECS until we get the nao back.
