Triad Air Quality

Triad Forecast

Synopsis and Discussion

Air quality levels remain in the lower Code YELLOW range this afternoon as mostly cloudy skies have trapped particle pollution under the cloud deck. AN deepening upper level low diving in from the north will provide very favorable large scale forcing that will supplement the strengthening of an offshore low pressure system expected to dump considerable amounts of snow across the majority of the state tonight and through tomorrow. The cloud cover combined with precipitating snow should keep particle pollution elevated enough to warrant Code YELLOW AQI for the Triad on Saturday. However, the strengthening of the low pressure system will also generate gusty northwesterly winds along the western side of the system that should lower particle pollution to Code GREEN by the evening (especially as snow lightens up and skies begin to clear from west to east overnight). Another shot of Arctic air arrives in the wake of the departing low pressure system, keeping temperatures well below normal Sunday and Monday despite clear and sunny skies. With that said, particle pollution will likely remain Code GREEN Sunday and into the following week. (Payne)
