The 12k and 3k might as well be two different models. May sound like a weenie, but I’d lean more on the 3k within 48 hours of onset. 3 Link to comment Share on other sites More sharing options...

I haven't seen the midshore above 12" on any model run recently. GFS and UKie have been close but cant imagine they are riding with that combo lol.

NorthArlington101 Posted 6 hours ago Share Posted 6 hours ago I’m going to pretend the FV3 is good. That is a much better thump.It would probably be fine but it barely starts in DC until like 6am.

NorthArlington101 Posted 6 hours ago Share Posted 6 hours ago It literally has precip starting at 10pm in DC, but okay. I may have blinked and missed things today but I thought we were supposed to wake up to more than 2” at 6am. I’m willing to cave to being wrong, though. Guess every flake sticks even if it’s not heavy from midnight-6. Link to comment Share on other sites More sharing options...

Fair - WxBell 10:1 maps have about half of that so I guess it likes the ratios, which isn’t crazy. Probably over analyzing the FV3 at this point. I’ll say you win 1 Link to comment Share on other sites More sharing options...

May sound like a weenie, but I’d lean more on the 3k within 48 hours of onset. They differ in more than just resolution, so they effectively are two different models (even though they have obvious commonalities). As you said, though, the 3 km is a far superior model, except for when it deepens hurricanes down to 850 mb. 4 1 Link to comment Share on other sites More sharing options...

Okay I'm about to go super weenie here, but that's where I am mentally. You probably already know this, but per this paper, the FV3 is being retired as well when RRFS comes online: https://journals.ametsoc.org/downloadpdf/view/journals/bams/aop/BAMS-D-25-0323.1/BAMS-D-25-0323.1.pdf The RRFS switched to MPAS for v2, which is (I believe) what we're watching slowly roll in. Supposedly, even v1 outperformed most high-res models, with some reflectively issues that have hopefully been resolved per that paper. I'll stop now. 1 2 Link to comment Share on other sites More sharing options...
