...DISCUSSION...
Upper low over the Southeast states at the beginning of the extended
period (12Z D4/Monday) is expected to slowly drift
northward/northwestward on D4/Monday and D5/Tuesday before
eventually becoming absorbed into a shortwave trough progressing
eastward/southeastward from the Plains into the eastern CONUS on
D6/Wednesday and D7/Thursday. More northerly trajectory of this
shortwave trough coupled with only modest moisture return should
mitigate the severe-weather potential through next week.
