Positive Height Anomalies To The North Of Hawaii And Just To The
East Of Greenland Will Both Act To Favor A Reloading Trough Over
The Western Conus Next Week.
The Models And Ensembles Show Good Agreement Through About Fri/D6 Before Timing Differences Over The Pacific Amplify Downstream Into The Pac Nw And Rockies.
Both The 00z Gfs And Ecmwf Presented Plausible Forecasts Within The Ensemble Spread Regarding A Respectable Upper Trough Digging Well Into The Sw States By Thu/D5 And Then Ejecting Onto The Plains Thereafter.
The Gfs Is Ahead Of The Ecmwf And Either Was Acceptable.
However... By Fri-Sat/D6-7... Energy Flowing Atop The Retrograding Northeast Pacific Ridge Presents A Whole Host Of Timing Differences Among The Guidance. Cues Were Taken From The
Ecmwf Ensemble Mean Given Its More Consistent Forecast Compared To The Gefs Mean Over The Past 36-48 Hrs... Bringing Lower Heights Into The Northern Rockies By Sat/D7 Rather Than Ridging Like The Gfs.
