7/21 -An Ozone Action Day has been declared for July 21st, 2022! Ozone has the potential to reach the unhealthy for sensitive groups (USG) category along the northern portion of the I-95 corridor on Thursday. Sensitive individuals, including the very young, the elderly, and persons with respiratory diseases such as asthma, should avoid strenuous activities during the afternoon and early evening hours. Hazy, hot, and humid conditions persist into Thursday as a weak cold front approaches the region in the evening. While the weak front will provide some clouds at times during the later afternoon hours, mostly sunny skies and southwesterly winds will keep ozone in the upper moderate to low USG category. Additionally, increasing humidity will allow fine particle concentrations to remain in the low moderate category.
7/22 - Another day of heat and humidity is forecast for the Garden State to round out the workweek. Sunny skies, temperatures reaching the mid 90s, and light westerly winds will be enough for ozone concentrations to remain elevated. There will be some chances for cloud cover during the afternoon hours which may help to limit ozone to the upper moderate category but the potential for ozone rising into the unhealthy for sensitive groups (USG) category will still be a possibility for the coming days. Increased humidity will allow fine particle concentrations to linger in the low moderate category in southern New Jersey.
