Medium-range guidance is in good agreement that an upper low will
drift within the southern-stream over the southern Plains from
D4/Tuesday through at least D7/Friday, its progress impeded by
strong subtropical ridging over the eastern CONUS. An active
northern stream is expected, but its location along the US/Canada
border will keep it north of the low-level moisture and instability
needed for an organized severe-thunderstorm event.
