  Wednesday and be locally strong and gusty Wednesday night.
  Winds will then shift to the west on Thursday and remain gusty.
  Wind advisories may be needed for Wednesday night and Thursday,
  especially in coastal and higher elevation locations.

* There is also a potential for isolated thunderstorms Wednesday
  night and Thursday morning.
