Cooler pattern

Our warm to hot stretch is coming to an end. Low clouds will blanket a good potion of the Bay Area Wednesday morning. Partly cloudy skies are expected later in the day. Highs should range from the low 60s to the upper 70s. A system will drop in from the north later in the week. Shower chances have been added to the Friday forecast. Highest chances will be focused up in the North Bay.
