....DISCUSSION...
Multiple mid-level troughs will traverse the CONUS while translating
within a broader west-northwest to east-southeasterly upper level
flow regime through the Days 4-8 period. Periodic bouts of surface
high pressure will reinforce a statically stable, cool and dry
airmass across most of the CONUS, limiting thunderstorm development.
One exception will be with the Gulf Coast states early next week,
when a surface low preceding one of the embedded mid-level troughs
will encourage onshore flow from the Gulf. Should this occur, enough
buoyancy will be in place (along with deep-layer ascent) to support
thunderstorms. However, buoyancy may be too weak to support a severe
threat.
