....DISCUSSION...
Medium-range model guidance shows a mid-level high centered over the
Desert Southwest during the extended period.  Models continue to
show an increasingly active/progressive flow regime near the
Canadian border with large model variability still evident in
shortwave amplifications/timing.  However, it seems there may be a
moist/unstable reservoir across the Upper Midwest during the
Friday-Saturday (day 6-7) in which perhaps greater severe potential
may be realized.  Will defer the inclusion of potential severe
highlights to later outlooks for model variability/uncertainty to
decrease.
