High pressure (Shaded “Arch” shape with blue arrows) is building offshore and will keep a northwest airflow with just enough moisture to produce cooler temperatures, late night and early morning clouds and possible fog, but not enough to produce any rain. A weak cold front will cool things a bit Friday, then high pressure returns to warm us up again for the weekend.
