Interesting that the GEFS clustering at this timepoint is significantly worse compared to multiple earlier runs (e.g., yesterday's 18z, 12z; today's 6z)

 

I mean, it's not better. It might be worse. But overall spread increased. There's no clear cluster.

I think it speaks to volatility in runs heading forward.

The ggem ensemble spaghetti plot looks less coherent now vs 12z as well. Not a lot of answers tonight.

It's amazing how bad operational models really are. 

The Euro is the only one we treat with validity. The GFS seems like it's become worse. 

After that, there's really nothing at this range. GEM and UKMET haven't nailed a storm in as long as I can remember.

The only assistance Euro/GFS gets is due to shorter lead time. When you can break out models like RGEM. 

Once NAM gets in its' wheelhouse, it's done better than a lot of the globals IMO. 

The only real guidance we have are ensembles. Which I guess makes sense considering everything.

But even still, EPS is the best.
