...DISCUSSION...
Severe-thunderstorm potential still appears low through the extended
range. An upper-level trough is expected to persist across the
eastern CONUS through the period, as multiple reinforcing shortwaves
move southeastward from Canada. A surface ridge covering much of the
central/eastern CONUS will inhibit low-level moisture return through
most of the extended range. Guidance suggests potential for the
surface ridge to eventually shift eastward by D7/Tuesday into
D8/Wednesday, allowing for some moisture return into parts of Texas.
This could lead to an increase in thunderstorm activity, but the
displacement between stronger deep-layer flow/shear and any
appreciable surface-based instability currently appears too large to
support organized severe potential through early next week.
