The ridge of high pressure responsible for the warm temperatures over the weekend and today is breaking down and a trough of low pressure sets up along the West Coast.
Cooler temperatures and areas of low clouds and fog have already developed at the beaches.
Tuesday a cold front will move through the Central Coast bringing drizzle/light rain to San Luis Obispo County on Tuesday night into Wednesday morning but futher south the front will likely not be effective producing any rain chances.
Temperatures on Tuesday and Wednesday will drop normal in the 60s and 70s, even inland areas drop into the 70s for highs.
High pressure is expected to rebuild across the Central Coast and should bring normal temperatures with plenty of night and morning low clouds and fog to San Luis Obispo County on Thursday into next Monday.
Former Supertyphoon Vongfong is forecast to head northeastward and become extratropical as it moves into the Gulf of Alaska next week. The leftovers of this system could actually produce unsettled weather for the Central Coast the following Thursday and Friday.
