...DISCUSSION...
Medium-range models indicate a mid-level low over the southern Great
Lakes will weaken on Sunday (day 4) as an attendant trough moves
across the Mid-Atlantic states and Carolinas.  If appreciable
instability can develop over parts of the Mid-Atlantic states, some
risk for strong thunderstorms could develop.  This scenario is
characterized by relatively high uncertainty at this time.  The
potential for severe thunderstorms will likely be lowest on Monday
as high pressure over the northern Gulf Coast states limits
destabilization.  Models indicate southwesterly mid-level flow will
become established across the southern High Plains downstream of a
potential amplifying trough over the western U.S.  Predictability is
too low during the latter half of the extended period.
