Forecaster's note
Current Conditions: High pressure remains in control today with wall-to-wall sunshine. As the sun heats the ground today, vertical and horizontal mixing of the air will create good air quality through this evening. *** Wednesday’s Forecast: Winds will be calm and the sky will be mostly clear Wednesday morning, which will allow the ground to rapidly cool into the lower 40s. The combination of the cold air near the ground and a lack of wind can trap pollutants near the ground, causing a period of moderate air quality during the morning hours. During the afternoon, winds a few thousand feet above
