Interesting..WPC completely removed the CMC and Ukie from their blend for this system.
"A general model blend of the deterministic GFS/ECMWF/CMC/UKMET was used for the first two days of the period (Wednesday and Thursday), with more weight placed on the GFS and ECMWF. For Friday onwards, the CMC and UKMET were removed from the blend and the ECENS and GEFS ensemble means were added in increasing amounts."
