The WPC says to take all the non GFS models including yesterday's 12Z run of the Euro and blend them together
No significant changes were noted with the closed low as it
weakens east into the Ohio River Valley through Tuesday morning.
Regarding the upstream, large scale trough, the 00Z UKMET trended
a little slower, while the 00Z CMC trended a little faster
compared to their 12Z cycles. The 00Z ECMWF also trended slower
and slightly weaker with the trough progression beginning Tuesday
afternoon.
From Tuesday through Thursday morning, the 00Z deterministic
guidance shows reasonable agreement outside of the faster 00Z GFS,
though minor non-GFS differences remain. Given some of the changes
from cycle to cycle, the final preference will not be to jump
completely on board with the non 00Z GFS suite of models (despite
their relative agreement), but to nudge in that direction from the
12Z ECMWF position. Therefore, the final preference is to take the
12Z ECMWF and blend it with a 00Z ECMWF/UKMET/CMC/NAM blend.
