WPC update:
--18Z UPDATE---
No change to the initial model preference. The 12Z ECMWF slowed
down the trough over the Gulf further, but the same preference in
that area (timing compromise) is still preferred. With the clipper
system, the 12Z UKMET trended closer to the GFS for the low track,
but the ECMWF remained closer south and was joined by the GEFS
Mean. The preference there is to continue with a non-NAM blend,
with a slightly higher weight on the GFS.
The GEFS is in more agreement with the Euro according to them
