I haven't seen anyone mention the UKMET yet, but it was a big hit today on 12z too. We will see if it follows up again tonight, but I cannot remember another time where pretty much every model showed such a similar situation 5-6 days out.

Yes the UK was on its way to being a big one at 12z. Hopefully 0z is a big hit to.

UK shows how it can go wrong. Little bit of SE Ridge and less blocking turns into cold rain and tears

Looks like the AI GFS tries to do the same thing. I don't buy the UKMET sending the low right up the Apps into a banana high setup like that. I've seen the models try do that many times over the years and typically what happens is it hits the wedge then comes down and around it or could Miller-B to the coast.

Euro AI also shows more of a cutter but strong CAD so lots of ice.. some of the models have trended towards dumping more cold in the west/midwest. That would not be ideal

If the HP is actually at least close to as strong as the other models are showing, I don’t think the AI models will handle this one well. They tend to underestimate extreme anomalous lows/highs because there aren’t enough examples of them in their training data. The other models being physics based know that, while rare, 1050ish highs can absolutely happen this time of year.


We need a combination of strong high pressure and a weak (but not too weak lol) overrunning type system. Any combination of weaker high or super amped up storm hurts us.

Looks like the UKMET and the  AIGFS are phasing too early over Arizona,giving this a chance to be amped up,delaying the cold press,and letting it cut.

If its going to phase it needs to over around the Rio Grande like the 12z Euro.Or you miss the phase and get a storm with either shortwave.

 

Just my opinion.
