Screw 984 lows east of OC...we like our snow with a low cutting hundreds of miles NW of us!!!

Dude if you go out to the midwest in a hot air balloon at about 6,000 feet and blow facing east really hard you might be able to reel this one in.

I was having fun with that but one thing worth mentioning. It’s low odds. It’s not the most likely outcome. But there are enough absolute snow bombs with that threat day 11-12 on the GEFS/GEPS/EPS that while the odds do not favor snow right now, there is the chance that could be a big storm if it breaks right. Being cold enough seems the largest obstacle att.

It actually trended better. But still too much ridging in front and not enough behind so the mid level trough goes neutral too far west and floods us with mild air on the southerly flow ahead of it. Strengthen the ridge to the west and weaken the ridge to the east and it’s suddenly a big snow. Like I said yesterday it’s a cows fart in the right direction from a snowstorm. But gotta laugh at that. That would be painful.

We spend the entire run after Saturday with below 0 850s EXCEPT for the 12 hours it’s precipitating...and it’s not a cutter..it’s a 984 bomb off Ocean City. SMH

This isn’t fair

I still think ice is a real threat. Im just am not a fan of ice so I don’t talk about it much.

12z GEPS was a good run.

I remember us talking with Wes before the Feb Storm when it was 10 days away about how perfect it looked on that run and “Shame it has no chance to be right”. lol

Exactly...we should only listen to forecasters who are perfect and never get anything wrong!

At the end of the day we manage to fail on this specific run with a 10 day period of below normal temps and near normal precip... but its because hidding within that is a 7 day period of bone dry followed by a 24 hour warm up when all the precip comes...lol On the other hand...back off the ridging a little bit...and suddenly there are 2 legit threats with a relatively minor adjustment.

I can't keep track of who is saying "cold" and who is saying "warm". I swore a little while ago someone was posting BAMWX stuff saying it was going to get cold and snowy. And just 24 hours ago twitter was lit up with "here it comes, cold/snow" posts and suddenly its the opposite. Don't get me wrong todays 12z runs were less than inspiring, but they were just one run, and werent a dumpster fire...just a step in the wrong direction. If we hadn't had such good looks recently we would think todays runs were great. Don't get me wrong its important to change with new information. I have changed my mind a couple times this winter...but each time it took a week of trending across different sources of information, not a single run. That is crazy.

That is kind of an exaggeration. It flipped from extremely cold to kinda meh. Next week is still very cold...but bone dry. If the EPS is right there is no chance of any precip from Sunday to the following weekend. That is where the problems start...its shifting the ridging up top too far southeast...instead of an EPO ridge its centered across central and eastern Canada cutting off the cold air source and creating too much ridging in the northeast for storms to possibly cut. It's not an awful look and we have snowed with some luck in such a pattern...but its not the really good look for that period of a few runs ago. After that it starts to get back to the idea of an eastern trough...but even then its more muted and the ridging up top is weaker. It was a disappointing run IMO. I wont deny it. But its not a total disaster either.

Not a fan of todays EPS. Slightly degraded everything. It's frustratingly close to good but each discreet event took a wrong turn. The weekend has been handled in detail. It moved towards squashing any hope of a system next week. And now trended towards the op GFS idea of sliding too much ridging into the east and cutting the day 11/12 storm. Snow mean took a major cut reflecting these changes. The overall longwave pattern hasn't changed much...but you can't see the smaller details that will determine the fate of each specific threat from range and as they have come into closer range the warts start to show. As of right now, this this run, there were too many warts on each threat window. Still leaves us at a good look day 15. The good news is each threat is "close" enough that small adjustments (and adjustments will happen) could put us back into a good spot for each one.

EPS supports the op. Getting to the range where it likely will most runs.

2-4 is a LOT from a storm cutting over Chicago in the middle of an uber ridge.

Euro is setting up a day 11/12 storm...no surprise that is when the GEPS/GEFS/EPS have said our next big chance at snow is. Before that we would need the ridge axis to back off some out west for the threat next week...otherwise its a southeast coast threat. I am realistic about snow...or at least I try to be. I got 7" last week and it stayed on the ground for 3 days. I got to enjoy it several times with my kids. If I can say 2 more similar events this winter... or one more good storm and a week of cold behind it to keep snow OTG...I will call this year a win no matter what the "number" says. Bottom line would be I got a couple opportunities to play in the snow with my children and a week+ with snow OTG to enjoy the scenery. Chasing a number we know statistically we are unlikely to reach 70% of the time is just a setup for...well being you.

I am always cautious when we see long range guidance spit out a lot of snow from a cutter. It does happen. And we remember those times it did. But in reality for every one of those there are way more that just end up being a mostly rain event. This one has a pretty good antecedent air-mass so it still might end up better then the majority...but the specter of big snows from these west track lows is a lot more of a longshot than we make it sometimes. Every few years one of them ejects a lead wave that directs a strong mid level wave into the CAD and we get a nice thump snow...and then we think there is a good chance of that every time a cutter comes along with cold air in front of it. What guidance is moving towards now is the more typical outcome. I am not saying there is no chance it doesn't trend back towards a nice lead wave...but odds always were and continue to be against it. We probably would be in a much better place mentally had the guidance not teased us for 24 hours with the rare snowy outcome from this type of thing.

relax...I know the rug pull over the weekend storm hurts a bit, but honestly had the models never teased us with some kind of crazy thump snow from a storm cutting to Chicago we would be in a much better mood. Nothing has actually failed yet except a setup that was never good from a longwave pattern POV to begin with. (assuming we don't make a miraculous comeback on the weekend WAA wave).

and without NWP there would have been absolutely NO FREAKING IDEA that there was even a remote chance at any frozen precip Saturday beyond simply taking a WAG. So yes at day 5/6 there is a HUGE spread...but that spread is between a little bit of non consequential snow/ice to rain and a decent thump snow to dryslot. As we get closer the guidance will narrow the possibilities until we get within 48 hours and they typically show a realistic range. But the bottom line is the NWP can outperform humans with no help from guidance at EVERY RANGE. Yea the range and accuracy isn't perfect at day 5 but before NWP humans didn't even attempt to forecast details that far out because it was impossible. You do not grade NWP on a realistic scale.

Also..looking at the last 48 hours of runs...good and bad, the actual strength and position of the shortwave is irrelevant to the results here. With the better runs were solely the beneficiary of a lead wave of WAA precip associated with strong mid level winds directed into the CAD in the mid Atlantic. But as the ridge continues to strengthen, sharpening the trough...there will be no wave and the WAA with the main system will be directed well to our NW.

Euro 36 hours ago Euro Now If this keeps up those with chase plans might want to look into Quebec City

More time to pump the ridge in front. Euro is close to a total non event now.

early on Euro still trending the wrong way
