.SYNOPSIS...

High pressure over the region continues light winds with afternoon
onshore surges developing along nearshore waters due 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.
