· Moderate to high Heat Impacts are expected on Monday, especially for those sensitive to heat.

· Cooling is forecast near the coast and in the coastal valleys by Tuesday, but most  inland areas will remain hot.

· Cooling will develop in all areas by Wednesday.

Weather Summary

A warming trend will continue into Monday for inland areas as high pressure continues to strengthen over the region.  Inland highs on Monday are forecast to range from 95 to 105. Most coastal areas will remain very warm on Monday due to continued light offshore flow, with highs near the coast forecast to range from 80 to 95.  A southerly surge is forecast to begin along the Big Sur Coast on Monday, as a shallow marine layer with fog advances from south to north. Thus, Big Sur will likely see some relief from the heat on Monday. The southerly surge will continue northward up the coast on Monday night and a shallow marine layer and light onshore flow are expected to be in place in all coastal areas by Tuesday morning. Thus, all coastal areas are forecast to experience significant cooling on Tuesday. Less substantial cooling  is expected along the San Francisco Bay Shoreline and in the coastal valleys on Tuesday. The inland valleys and hills will remain very warm to hot on Tuesday. All areas are forecast to cool by Wednesday as the marine layer deepens and onshore flow increases.
