Sea breeze winds will linger through 9 PM and then ease with wind speeds trending light to calm. The overnight inversion will begin to trap smoke by 9 PM and the linger east winds will push it westward along SR-26. Early Thursday, there is the potential for patchy fog development and the visibility degradation may be enhanced in areas of heavy surface smoke. Though mixing heights will push toward 6k ft, light transport winds will lead to an overall poor dispersion Thursday. Hot and dry conditions will persist through the end of the week with low humidity around 25-30% and temperatures nearing record levels. The sea breeze will push across the fire area again Thursday around the same time between 7-8 pm, turning variable winds southeasterly around 10 mph. .REST OF TONIGHT...
