DEEP LAYER MOISTURE WILL ACCOMPANY FRONTAL BOUNDARY INTO THE AREA ON THURSDAY WITH ONSHORE FLOW DEVELOPING BEHIND THE FRONT. DECREASING THICKNESSES WITH THICK CLOUD COVER AND ONSHORE FLOW WILL KEEP THE TEMPS IN THE 80S AS OPPOSED TO THE 90S. MAY SEE HIGHS ONLY IN THE MID 80S ON FRIDAY AS ONSHORE FLOW BECOMES BETTER ESTABLISHED.
