For 5/3/2024
[ The forecast is updated daily by 3:30 pm EDT. ]
Most regions are currently trending code yellow on this Thursday. For Friday, the strong high pressure will begin to shift to the east, and winds should become more south/southeasterly, which will help to bring in some cleaner background concentrations. Moisture will also increase as the next system approaches from the west. Increased moisture and some more cloud cover will help to decrease ozone formation. Thus, all regions should be CODE GREEN.
