It's Independence Day, and most of us look forward to watching our local fireworks displays that light up the night sky with colorful designs and loud booms. But the even the slightest weather variations can make a huge impact on these night shows.
Many cities can still hold their firework displays in the rain, provided spectators don't mind getting wet. Unless we're dealing with torrential downpours, fireworks can still be shot in the rain. If it's damp, the fireworks are put in water-proof bags in sealed canisters that allow the explosion to take place before they get too wet. It turns dangerous though when there is lightning-packed storms, at that point officials cancel the display where folks won't be at risk of getting struck.
It's important that the wind flow is moving in the right direction, not in the direction of the crowd. High winds can cause a fire hazard. It's also interesting to note that with a tropical, humid air mass, the duller the colors will look in the sky. If weather conditions are parched with extremely low humidity, fireworks shows can be banned especially if fire weather watches are in effect.
