Synopsis and Discussion

Sunny skies and warm temperatures have allowed for ozone to climb to mid and upper code YELLOW, despite the windy conditions. Particle pollution is also in the low to mid YELLOW category. High pressure will continue to control the weather through Saturday providing warm temperatures and elevated, code YELLOW ozone. A few more clouds will enter the picture, Sunday, as a weak disturbance moves through, helping to lower ozone back to upper code GREEN. Partly sunny skies will return, Monday, and combined with the warm temperatures, ozone will rebound back to code YELLOW. Particle pollution will remain code YELLOW throughout the forecast period (GENTRY).
