Day 4-8 Convective Outlook

...DISCUSSION...
Large spread among guidance is apparent during the Day 4-8 period.
Most guidance develops an upper cyclone over the central or eastern
U.S. for much of the period, while an upper ridge persists over the
western states. However, the GFS suite of guidance is much more
progressive with the central/eastern upper trough/low compared to
the ECMWF, and eventually develops a broad upper ridge over much of
the CONUS late in the period. Given vastly different forecast
solutions, confidence in any severe potential developing during the
forecast period is low.
