For 7/5/2025
[ The forecast is updated daily by 3:30 pm EDT. ]
Most regions are currently trending toward the green/yellow threshold for Independence Day. For Saturday, coastal regions could see an increase in clouds and even some storms by the evening, thanks to the tropical disturbance off the SC coast. Other areas will be almost cloud free, but an easterly wind should help to keep most pollutants dispersed, even though the atmosphere will be drier, which typically enhances ozone formation. Thus, all regions should end CODE GREEN.
