There won’t be any excuse not to walk off your Thanksgiving dinner. Forecasters are calling for mild, sunny days in the Bay Area through the holiday Thursday, with temperatures approaching the 70s both along the coast and inland — perfect for getting outside. Mornings will be a bit cool, with lows dipping into the 30s inland, forecasters say, but temperatures will heat up in the afternoons. The clear skies follow a series of weather systems that brought the first significant rain to the region since Halloween. San Francisco recorded 1.9 inches Wednesday through Saturday, bringing the total since the July 1 start of the rain year to 2.5 inches.
