Day 4-8 Convective Outlook

Valid 251200Z - 301200Z

Any appreciable severe weather potential during this period may
largely hinge on tropical developments possible by late in the work
week, both near the south Atlantic coast and near the lower Texas
coast.  The latest medium-range guidance suggests that the latter
feature may become the more prominent tropical cyclone, which may
progress inland across the Texas coast, before the remnants
eventually accelerate northeastward into/through the lower
Mississippi Valley region next weekend into early next week.  The
extent of any possible associated tornado risk will depend on many
factors, some of which remain unknown, and most of which are
characterized by low predictability at this extended time range.
