lower to mid teens inland and upper teens to around 20 degrees
along area beaches. Patchy black ice on roadways, bridges and

A Hard Freeze Watch remains in effect for inland zones Thursday
night, where temperatures could dip to around or just below 20
degrees.

Southerly flow returns by the weekend. With warm, moist Gulf air
flowing atop cooler nearshore waters, dense fog formation along
the coast looks likely into weekend.
