...DISCUSSION...
Overall, the long range pattern will feature a ridge centered over
the southern High Plains which may shift slightly west through the
period. Some severe weather may occur within the northwesterly flow
pattern from the northern Plains to the Ohio Valley Tuesday/D4 to
Thursday/D6, but confidence is not high enough for probabilities at
this time.  There is an emerging signal for a seasonably strong high
pressure to build into the eastern CONUS and shunt most of the
richer low-level moisture to the Gulf Coast states. If this occurs,
a relative lull in severe weather potential would exist from the
Mid-Atlantic and Northeast to the Upper Midwest into next weekend.
