....DISCUSSION...
Severe potential appears low during much of the period, with an area
of interest on D7/Tuesday in the northern Great Plains vicinity.
Guidance consensus suggests a large-scale trough should approach the
West Coast by about D5/Sunday. An embedded shortwave impulse is
generally projected to move northeast across the central Rockies
into the northern High Plains early next week. This may yield at
least a low-probability severe threat, seemingly centered on
D7/Tuesday, in parts of the Dakotas to eastern MT. Typical spread
for this time frame and only modest run-to-run continuity suggest
predictability is too low for a 15 percent severe area.
