Synopsis
A diurnal wind pattern will likely persist through the week even as a weak front drops into the area Wednesday night. This front will drift over the coast and into the coastal waters Thursday and Friday but as it stalls the winds will still be mostly dictated by daytime heating and slight cooling at night. With that light to moderate onshore winds each day driven by the sea breeze and light to moderate offshore winds each night driven by the land breeze. Storm coverage will start to increase Wednesday but look for storms to really ramp up by Thursday with widespread coverage by the weekend. Winds and waves will be locally higher near any storms along the increased threat for dangerous cloud to ground lightning. Small Craft Advisory conditions may develop over the Gulf waters by next weekend.
