The heatwave is expected to strain California's power grid, particularly during the evening hours when solar generation decreases. Elevated humidity and persistent warm nighttime temperatures will exacerbate cooling needs, making it harder for homes and businesses to cool naturally. This could lead to higher energy costs and discomfort for residents, especially in areas like Burbank, where humidity may make temperatures feel like the low 100s. Additionally, at least 24 locations across the state may set records for high minimum temperatures, further intensifying the impact.
