There is still a wave around the 24 and it’s close. It’s a little north on most guidance but given season trends don’t mind that

I’m sorry did you forget the substantive part of this post? Oh wait it’s YOU. Silly me. Carry on.

You guess? What’s your point? There is no way to know whether that storm would still be snow now without knowing what the temps were DURING the snow. Not 12 hours before or after. Thats irrelevant. But oddly you know exactly what the temp was when it don’t matter but can only guess when it’s pertinent to the discussion. You think you’re clever when really it’s transparent exactly what you’re doing. Go BS somewhere else. Everyone here knows your act and it’s old tired and boring.

Because someone always baits us into that AGW to shit it down. As long as no one takes the bait…

This. I’ve told you and others this before. Places south of us are not getting more snow than us. I showed you the snowfall the last 10 years in a ton of random southern cities and none have more snow than Baltimore over the last 10 years. Not one. Some had more snow one single season. Others more a different year. This is perception bias. You don’t pay attention to exactly where the storms missing to our south hit. Or the frequency. Yea New Orleans got that big snow last year. But that’s the only damn big snow they got in the last 10 years! Charlotte got one a couple weeks ago. But they’ve only had a few storms over 10 years! Same with Raleigh, Nashville, Dallas, Little Rock, find me one city south of us that actually has more snow. Do some research before you make a declarative theory or statement. Don’t go on perception. Yes we will be like Raleigh and get some southern sliders. So every 3 years we will get one damn snowstorm. But hey we will get that storm that used to go south of us. Winning!!!

For the record I am not talking about human AGW I am simply discussing how our snow climo is changing and I am not taking the bait to engage in the causation AGW debate

Except it’s been made very clear to us that the larger discussion about cyclical v man made and all that is strictly off limits for political reasons. That’s why you don’t hear people commenting on it. It’s off limits. The fact it’s warmer now than 30/50/100 year ago is just a fact and how it affects our snow climo v 30/50/100 years ago isn’t political.

I got 1” last week lol

If there was it would be snow NW of 95. A more N more amped system actually is colder in this case because it’s only the surface that’s torched and heavier precip would dynamically cool temps more

@Cobalt you’re 100% but please delete and just ignore that jackass. He is baiting you. And worse when he gets you to engage in the more political aspects then suddenly someone finds a mod and cries and then the whole thing gets shut down. It’s the same game. He is baiting you. Delete and move on. Anyone dumb enough to believe what he said isn’t worth your time and is too stupid to understand the science you’re using to prove your point anyways.

Don’t take the bait just ignore this jackass. Please.

JFC no one cites snowstorms from the god damn ice age. This is irrelevant to this discussion. Everyone has a sense of what they consider our climo and normal based on modern recorded history. When we say it’s getting warmer everyone knows we mean in the last 100 years not comparing to 10,000 BC. This is gaslighting of the highest order.

The ensemble means have a snowy bias. I’ve discussed why before. Part of it is skewed results from big snow outlier members. The median right now which is a better indicator is only 1” for DC and about 2” for Baltimore and you. That’s a much more accurate indicator of what the model thinks the chances of snow are. You could also look at the probability output and see you only have a 40% of 3” over the next 15 days. So it’s saying you have a 60% of NOT getting any significant snow! But everyone pots the colorful mean maps because they always show more snow because a handful of unlikely 20” members of the ensemble skew the snow higher! There are other issues too but I’ll leave it there. However…you still want the snow output to be good. Because yea you just said it. When thay be bad we NEVER snow! It’s no hope! When they do show snow it doesn’t mean we will snow it just means we have a shot. I’d say today’s EPS would say about a 30-40% chance of some snow depending on where you are for the majority of the area. So that means it likely WONT snow. But it’s better than having no fucking chance. I swear to god how are some people on here for 20 years and still haven’t learned how to use a tool or how probabilities work!

This is true of the cause of the warming. But a discussion of the effects of the warming on snowfall does not have to include that unless someone just wants to be belligerent. it’s ~2f warmer now than 1970. 3f since 1950. Those are facts. We don’t need to bring what’s causing it into it. A discussion regarding how it’s impacting our snow doesn’t require us to agree on why it’s warmer just the reality that it is. And anyone who is going to be belligerent enough to deny it’s warmer, as if thermometers are subjective, well if someone came in here and said we can’t discuss precipitation because liquid isn’t real we wouldn’t listen or let them alter our behavior. I choose to treat anyone who wants to act crazy and pretend it’s not warmer the same way. I don’t alter my behavior to placate crazy people. Again this isn’t about why it’s warmer. Snowstorms don’t care why! This is just about the effects of that undeniable factual warming!

Except you didn’t provide the relevant data. How warm it was the day before doesn’t matter. How warm was it while it snowed? Did the temp drop to 27? If so 2f wouldn’t have mattered and that’s still a snowstorm now. But if it was 32 during the snow, I got bad news for you regarding what math says the +2f would mean

Not globally but the rate of increase does continue to accelerate. What’s happened that caused the sudden post 2016 decline in snowfall was a pattern change to a hostile pacific much of the time which has made the 2f matter more because we’re stuck in a warm regime most of the time where even when we do get snow threats we need Them to work with marginal temps and those marginal temps are now warmer. Some of this will get better when a better long term cycle emerges. But make no mistake we’re bleeding snow even in those. For example the last time we timed up a favorable Atlantic and pacific in the 2000s Baltimore only averaged 21” during that period. Better yea but only slightly above what the 30 year mean was anyways. At the same time NYC and Boston were averaging 150-175% of normal! That should have been us! And in the 1960s when a similar pattern happened it was us. But it’s warming so the core of the snowfall shifted north. And we got scraps on the southern edge of the max snowfall anomalies despite a perfect pattern cycle. That’s going to keep happening and get worse. we will continue to see short term cycles of less and more snow but over top of that is the long term decline. Each up will be less up and each down will be more down and eventually Baltimore will have a winter climate similar to what Raleigh used to have where snowfall is an extreme anomaly and not something you expect in any given winter.

Will most of the column from h85 down is nearly isothermal so they all start warming together in this case. Slightly. But the equation gets a lot harder the further southwest you go right now.

True BUT this topic never comes up in a vacuum. It’s not like someone comes in here and just says now let’s talk about climate change. What happens is we get a synoptic situation that is being impacted by climate change. It’s impossible not to note that this storm we are tracking right now is being impacted by it being warmer. You’d be under an advisory if not a warning right now of it was 1970 and 2f colder with this same exact synoptic setup. That discussion is muddy because it bridges both topics. And I don’t think the people that shit it down do so because it’s the wrong thread they do so because they are uncomfortable with the topic. Either because they are in denial about what it’s doing to our snowfall or because they are in denial because it’s inconvenient to their preferred ideology. I have no patience or fucks to give about either of those reasons.

This storm is taking a perfect track. It’s just too warm for DC

The high resolution models can pick up on them but the issue here is the higher mountains in our area are southwest and in this case south of the thermal boundary that sets up. The high resolution do show more snow on Catoctin and parrs ridge in Maryland.

I don’t agree with the argument but some argue C02 concentration are cyclical. Look I’m on your side I just don’t want to muddy the snow argument because what’s causing the warming doesn’t matter to the is the warming hurting our snowfall argument. Those 2 debates can be severed.

As long as NWS doesn’t issue any advisories and downplays it we are good! Let’s reverse psychology this into a snowstorm.

To be fair the nam and euro were pretty identical the last 2 runs. We don’t know what the euro will show this run yet!

The snow alg on wxbell is flawed for the AIFS ensembles. It seems to count anything remotely close as snow. I tried to figure out what’s wrong but it just seems like someone accidentally set the freezing temp as 35 instead of 32 lol. It’s not the model it’s the clown snow map wxbell makes.
