NOTTINGHAM, MD—The Maryland Department of Environment has issued a Code Orange Air Quality Alert for Thursday.
A quickly degrading airmass, favorable trajectories transporting modestly modified air, light winds, and hot temperatures will increase the probability of USG ozone, particularly in the Baltimore area Thursday.
A Heat Advisory will be in effect for the Baltimore area until 7 p.m. Severe storms are possible as well.
Cleaner air, though likely still in the Moderate AQI range, is expected elsewhere, particularly further from the urban, I-95 corridor.
As an upper level low approaches the area Friday, increased chances for clouds, precipitation, and cooler temperatures should return good air quality to the region.
