It is possible that there may be better agreement with tonight`s
guidance as one of the many players is now over the CONUS upper
air network and may be sampled better. This is a vigorous
shortwave that is currently diving south along the west coast.
This shortwave will have some influence on another shortwave/mid
level close low farther north in Canada. This interaction could
be important because the northern energy may end up being the
main driver that digs down and helps spin up the surface low.
