SnowDreamer Posted January 25, 2021 Share Posted January 25, 2021 On a separate note, does anybody have any guesses why the CWG map is oriented like this? Most models I have seen show a gradient nothing like this angle. Link to comment Share on other sites More sharing options...

NorthArlington101 Posted January 25, 2021 Share Posted January 25, 2021 Checking on the QPF, the NAM is an outlier, but it's not like it would take a crazy jump to get the other guidance in line. 50 or less miles north isn't a totally unreasonable ask...

Ok, that was my snarky answer. The better answer builds on that a little more. It's still one of the best models for handling shallow cold air masses and things like terrain-induced wind storms in the west and fog. Ultimately, the NAM nest is a way better model, but it's driven by the 12 km NAM, so that's another reason to keep running it. Ultimately, the NAM nest and parent are frozen (no more development is being done on them) and will likely be retired in ~3 years. 3 Link to comment Share on other sites More sharing options...

The NAM is colder than the GFS which is notoriously crappy with low-level temperature profiles, and the NAM (in conjunction with the HRRR and some other meso models) is telling me that if I'm north of the Beltway tomorrow evening, I have a decent shot to see a modest accumulation of snow. I personally rarely look at the 12 km version of the NAM, because the NAM nest is a much better model, and I think that is a good strategy here this evening with the 00z cycle. 1 4 Link to comment Share on other sites More sharing options...

Someone smarter than me can chime in but I don't think this is one of those scenarios. Think we'd need the high QPF/rates from the NAM to give those outside of the favored areas a chance at a boom.

Thank you for contributing...and in case you haven't noticed his ridiculous NWP conspiracy rants drive me absolutely crazy. It's not the stupidity of it...its the extreme disrespect to basically accuse so many people of that kind of thing without any evidence to back it up. The audacity to think its acceptable to just make up some BS like that and impugn the integrity of others without a shred of any evidence to support the accusation. 2 Link to comment Share on other sites More sharing options...

NorthArlington101 Posted January 25, 2021 Share Posted January 25, 2021 FWIW, thought the HDRPS and Para looked cold enough. Just gotta will it north.

It’s all we’ve had for 30 years and they are not looking into any different methods. The very nature of ensembles is to further the cover all bases method such that come funding time one of those 30 panels can be presented as confirmation to the unknowing Dept of Commerce people. Im a weather nut also and let’s face it the cartoons are fun to look at. They are just not predictive of weather but rather illustrative of it Not a troll either but rather experientially seasoned. Used to be 100+ of us clamoring about models back in 2005, over time as the blooms faded participants of regularity have shrunk to 20 all of whom vigorously defend their baby. I thank all of you who helped educate me about 850s and 500 and a Few other things but models and many of the alphabet soup of indexes have not proven to be general fund of knowledge enhancing Thank you for the courage of your comment, more of same is needed even with the chastizements we face Oh no you don't...you started all this by dropping these nuggets for no reason in both storm threads earlier today. You didn't post in banter. And now you want to pull this passive aggressive BS "not the right place" crap because you're rightfully taking a beating for the nonsense garbage you posted. 3 4 Link to comment Share on other sites More sharing options...
