The passage of a weak disturbance will increase daytime shower 
and thunderstorm coverage across all local waters today. Caution 
flags for the offshore waters through the afternoon. This 
persistent onshore fetch will weaken through the week as eastern 
surface high pressure expands into the northwestern Gulf. Rain 
chances will increase over the weekend as western Gulf upper 
ridging weakens and general troughiness develops in its wake.
