"Stay Cool and Enjoy Fourth of July Festivities in California's Heat Wave"

The National Weather Service predicts that Tuesday's Fourth of July fireworks in San Diego County will still be vibrant, despite the formation of clouds along the coast due to a weakening high pressure system. The clouds could cause smoke from the fireworks to disperse more slowly, but inland skies are expected to be mostly clear. The wind is not strong enough to disperse smoke near the ground or spread firework embers. The evening humidity along the coast is expected to be around 75 percent, which is unlikely to significantly affect the brightness of the fireworks. The absence of monsoonal moisture means there won't be lightning, and a nearly full moon will rise late in the evening, after most fireworks shows have ended.
