.SYNOPSIS...
High pressure over the region early this week brings light winds

to the Atlantic sea breeze. As the high pressure system shifts
northeast mid to late week, a predominant east to southeast wind
pattern takes over and persists into the weekend. This onshore flow
will draw in higher moisture levels, resulting in scattered showers
and embedded thunderstorms Thursday and Friday through the weekend.
