Clouds mainly stick to the Coast tonight. Only a few slip into the Bay and coastal valleys. Lows cool nicely into the middle 50s to lower 60s. Communities near places like Antioch only cool into the middle and upper 60s.
Our heat peaks tomorrow and creates a Moderate to High Risk of heat illness. A HEAT ADVISORY is in effect from 11 a.m. to 8 p.m. on Tuesday. A Spare the Air alert is also in effect as stagnant air and smoke from the Six Rivers Lightning Complex Fire gather in our sky.
