Seems that way to me too. Often seems like they're one cycle behind the models.

Seems reasonable. I'm in Monroe (maybe 10-15 miles northwest of you) and my best guess for my backyard is currently 6-9...although still wouldn't be surprised by substantial changes in either direction

I think it also attempts to adjust for model biases. That has to be the reason why the blend is currently higher than any of the models that it’s blending. there was a slightly confusing post in the mid Atlantic sub forum that suggested that a few recent high ratio storms that were positive busts account for the strong positive adjustment that it’s clearly making here

For the Euro, are you saying that of the 1.1, 7.7 inches should be snow and the rest would be sleet + freezing rain? Or would the 7.7 include snow + sleet?

That would be a fair criticism if he was telling us what he thought was most likely to happen. But that's not what he posted about...he posted about the possibility of how the storm could underperform...so it makes sense that he'd cite the models that give us reason for concern.

Not sure why everyone is on eduggs' case. He's not saying we won't have a big storm. He's giving concrete reasons why there are concerns that the storm MIGHT not meet high end expectations. That's doesn't seem especially controversial. Even his statement that at four days, the low end up possibility is 0" shouldn't be especially controversial. It's unlikely, but we've seen it happen before.

I think the guy who people refer to as Yanksfan was actually Yanksfan23 or something

Is it just me, or are both posts above in response to the request for a Kuchera of the AI Euro, actually 10:1 maps, not Kuchera?

Start thinking about it, but no need to pull the trigger yet unless there's limited availability on Saturday flights

At least since last week when the GFS had a run that buried OH, PA, NJ, WV, NY, CT, RI and MA in 3-6 feet of snow.

At least an inch of new snow over the past two hours in Monroe township nj

As Sacrus said above, it’s snow. At least in Monroe. I’d describe it as more like moderate snow than heavy snow though.

That's pretty wild. Looks like a total of only 6 out of 34 happened earlier than January 15.

Ah I see. The ranges were right for the 'Expected' amounts, which seem to be equal to the top of the 'experimental, probabilistic amount ranges'. Confusing way to present things, but at least kind of makes sense.

The numbers showing on the maps have no correlation with the numbers on the map key. For example, Syosset and Stony Brook say 3-8" on the maps, but their color says 8-12" on the key. Similar discrepancies throughout the map.

Good trends this morning for those of us in Central NJ. No matter how long I'm at this, I STILL underestimate how much things can change at the (relatively) last minute...I was feeling pretty discouraged last night (I'm in southern Middlesex, near the Monmouth border). At this point, I wouldn't be surprised if I get an inch of sleety slop and also wouldn't be surprised if I get six inches of snow.

Not sure comparing Lake Placid in the 80s and 90s to NYC area in 2020s is a good gauge of climate change. Pretty sure most winters are still quite cold and snowy in Lake Placid...even during Christmas week.

"This is the hardest I've seen it snow in years" - typically posted about every 2-3 weeks during the winter, anytime rates exceed one inch per hour

If you're saying "most of the snow in La Nina comes early, so by the end of December a substantial portion of our opportunity has passed" - sure, I agree 100% But I think a lot of people bring up the rule of thumb as a way of predicting what will happen in Jan+Feb, implying that good Dec means good Jan+Feb and bad Dec means bad Jan+Feb. That might be true, but you can't analyze it by looking at correlation between Dec and full winter totals

One other point about the "if you don't exceed 4 inches by end of December, it's going to be a below average year" rule of thumb...you're kind of cheating if you use December to predict the full winter (which includes December). Much more meaningful test of predictive power would be "If you don't exceed 4 inches by the end of December, then the REMAINING portion of the winter would be below average. Obviously, with Nov+Dec generally not accounting for a very large proportion of the winter's snow, it's not a HUGE problem, but this like a less extreme version of saying "If a hitter is batting below .300 on September 1st, he's unlikely to hit .300"...obviously true, but not much of a prediction of what will happen

You've also cherry-picked specific cities, many of which have most of their snow driven primarily by lake effect snow. These apparent trends are also somewhat sensitive to exact start and end dates. For example, for Rochester and Syracuse, if you shift the entire chart about 4-5 years earlier, I'm pretty sure there would be no trend. I was in Buffalo from 1988-1992 (just before the start of your chart) and that was not a snowy period in Western NY and the past 5 years have not been snowy. I'm not saying that there isn't a gradual downtrend, but it's pretty easy to overestimate the pace of the trend by looking at a limited subset of the relevant data

Read my post. Pretty sure it explains the confusion/contention

Been meaning to mention this for a while. I think a lot of people (including some professionals) are misinterpreting the implications of the 12z and 0z being more accurate due to ingesting more fresh data. This means that right after the 0z comes out it's going to generally have better verification scores than the 6z does right after it comes out. It does not mean that after the 6z comes out, the 6 hour old 0z is going to still be more accurate than the brand new 6z. The 6z has access to whatever fresh data it ingested PLUS whatever was available at 0z for the data points where it hasn't ingested anything new. So it should still be better than a now-stale 0z. To summarize: maybe take 6z runs with a grain of salt, but still put more stock in them than in older runs

A reminder for those who have incorrectly stated that we had nothing to track early last winter...

Yeah - lasted 10-15 minutes. Probably somewhere between .25-.5 inches I'd estimate I think we're in the same town, unless you've moved anytime in the past 10 years or so
