But it is warmer now, on average than it was a couple/few/several/100 decades ago, on average over time. Yeah no doubt its warmer. That shouldn't be affecting model performance though....in fact, if anything, our model performance has vastly improved in the past decade. Tracking a storm even 7-8 days would get you laughed off the forum with a weenie tag 10 years ago. Now, we've often tracked some of our biggies that far out (or even longer). It used to rarely be like that....now it's not super uncommon even if still abnormal. I think the model changes are just more amplified in everyone's mind when we haven't gotten shit for snowstorms and we keep missing our brief windows of favorable setups. 1 1 Link to comment Share on other sites More sharing options...

Part of the problem too is one's expectation and interpretation and also there are so many products offered and available and people run away with them and it just leads to chaos (Twitter is a great example of this). For example, with winter weather, you see model snowfall maps tossed around left and right and some try to use those solely for forecasting a storm way out or to hype and just give an unrealistic expectation. With severe weather you see it with the potential hazard types on the SHARPpy plots (people go buts when it shows TORNADO or PDS TORNADO) or the UD helicity swaths or SIG Tor and now these CIPS analogs. But I don't think models are as terrible as some make them out to be, it's just they're being misinterpreted. Link to comment Share on other sites More sharing options...

Data overload and also unrealistic expectations of model accuracy at long lead time. At any rate. 18z GFS looks like a snow to rain event. Still quite a bit different than the euro.

Typhoon Tip Posted January 6, 2023 Share Posted January 6, 2023 It's doing something similar to the GGEM's 12z solution ...which is to split open the event into two distinct phases... The first is an intense isentropic lift event, with perhaps 6-9 hours for a band of impressive QPF to move through, ...transitioning from snow to rain as it goes. Then it's ENE gales into the coast and elevations inland, with mist everywhere, while the low deepens east of Jersey with the capture, cut-off drifting E from there. At that point, there's modest dynamic support of cooling and CCB cat-paw band might end with accumulating snow. Snow-rain-snow away from the coast in total, but there's two distinct pulses of QPF. I'm not sure the models are handing the slow movement of the atmosphere ( can't believe I'm saying that since 2010!!) ...but much in the same way they screw things up when the flow is fast. In this case...there doesn't appear to be any reason to eject the isentropic engine like it's doing there around 180 hour and running up the Maine coast like that. Lows don't typical just puke their guts and turn inside out like that. Link to comment Share on other sites More sharing options...

When you have high heights all across canada and into newF, your cold source is marginal at best to get locked in. I couldn’t care less about some blue H on a surface map which retreats faster than your weenie in pool of cold water in April. Link to comment Share on other sites More sharing options...

Typhoon Tip Posted January 6, 2023 Share Posted January 6, 2023 well, anyway... it's incrementally improved for winter enthusiasts ...I wouldn't sweat much. The signal for 12th -16th has really been consistent. Folks can't expect to be model doped with d-drip at this range. Especially because we're in a marginal atmospheric space and probably still will be heading into the period of time. There does not appear to be any present index suggestion that a major correction in the models is necessary to happen... Today was marginal. Finally got its act together...with far less dynamic power as that that thing on the 14th has, too. It was modeled pretty warm all week - then yesterday we we had to put Advisories up. So, I'm neither optimistic nor pessimistic... 1 Link to comment Share on other sites More sharing options...

Yes, 100% and this is the difficulty of having a discussion where climate change enters the chat. Things can be getting warmer BUT also not be the main cause of our ratter winter so far. Both of those statements can be true. Climate change is not putting a mean upper level trough over the inter mountain west with above normal heights over us. That’s just a shitty draw on a pattern that does not want to budge. Link to comment Share on other sites More sharing options...
