....DISCUSSION...
Models are generally in good agreement through about Monday/D6,
depicting an amplifying upper trough over the West, with upper
ridging centered over the Great Lakes and MS Valley. A gradual
increase in southwest flow aloft may eventually overspread parts of
the High Plains, but there is still uncertainty with the progression
of this trough. Even so, moisture and instability will not be
particularly strong over the Plains, but may still favor scattered
strong to severe storms with time. At this point it is too
conditional and uncertain to introduce any low-end severe areas.
