Not sure yet, but I think 2” is certainly in play. I think Monday might be a fun wintry day. Snow in the morning, some sleet, pause, a bit more snow and sleet in the evening.
The shutout pattern in December had that Pac jet blasting into the west coast. Now it's barely making it to the dateline before splitting. That's a pretty good look actually. If anything we want it to extend a bit farther so that ridge is closer to the west coast. It gets there right at the very end, but 14-16 days out, etc. That jet across the CONUS there is primarily STJ.
True. What doesn’t hold water for me is how the gfs handles the CAD in today’s run. High is stronger and in a better position and just has no holding power on temps. Don’t buy it at all. GFS consistently sucks with CAD and don’t think it’s right now.
There are no trends yet. Yesterday the models “trended” toward a weaker primary. Last night they went the other way. It’s still pretty scattershot within a plausible envelope of possibilities. We know the general setup right now. Details that will impact our sensible weather still have to be sorted out.
Overnight runs also made a clear step towards more overrunning precip Sunday night and Monday and link that with the main event Tuesday. Still obvious we don’t have this locked down.
Eh don’t know about that. Cyclonic flow around a distinct LP area will help reinforce CAD and bring more precip. Some of the random great looks we’ve had for this event have the energy split around 50:50 between the primry and coastal.
18z GFS definitely puts more energy into the piece that transfers to the coast. Subtle differences from 12z, but ends up a bit better for us in the only way we care about.
I could be wrong, I was just going off memory. Could just be 7/8.
On a related note, I wonder if the SSW *does* end up actually saving this winter from being a raging dumpster fire for all of the eastern CONUS. Will be an interesting study.
