Just fringed us, but this wasn't there since 12z yesterday. Very close miss. Won't take much to shift it to a 2-4/3-6" hit

Slowly coming back to the original idea and now the ukmet and euro solutions

It'll figure it out and look like the other models, but not until it plays dumb for a bit.

Honestly laughable differences on the GFS from 6 hours ago. We need to put another upgrade on the table for this thing. NCEP really should consolidate to a HiRes model/HREF type output that goes to 180 hours and eliminate NAM, SREF, etc. A short range hi-res and that and be done with it.

Model is performing miserably in verification scores. It needs help

AIFS is smoking the GFS in the 6-15 day verification scores

Edit - even blows GFS out of the water in 1-5 day scores, wow

GFS might suppress this one, but might be overdoing the cold/PV again like it did last time.

That 1050+mb high it keeps showing would challenge records for the highest barometric pressure in the Central Plains.  Hopefully that’s an indication it’s overdone.

January 7, 2015 set the previous records in these cities:

  • Grand Island, Nebraska (1056.9 millibars)
  • Lincoln, Nebraska (1055.9 millibars)
  • Omaha, Nebraska (1055.3 millibars)
  • Concordia, Kansas (1055.1 millibars)
  • Topeka, Kansas (1054.3 millibars)
  • Des Moines, Iowa (1052.15 millibars)
  • North Little Rock, Arkansas (1045.07 millibars)

Do you have that graphic? Didn't realize they were running Euro AI verification #'s. 

I do, but its through my job. We compare AI models with all other NWP models in the 1-5, 6-10, 11-15 day ranges.

That's awesome. Wish we could see but great to perform that service to assist the general public. You'd think the AI "models" would only get better over time.
