Blanche Bays...

Expect to see a gradual return to typical summertime shower and
storm activity from this weekend into the next work week. Weak
surface high pressure meandering around the northwest Gulf today
and early Sunday will keep seas low and rain chances fairly low.
By Sunday afternoon and beyond, expect daily chances for scattered
to numerous shower and thunderstorms over coastal waters. Seas
will remain low through the period as patterns stall and weakness
remains overhead.
