Forecast Discussion:
A weak weather disturbance will lead to a chance of showers and slight chance of thunderstorms today as it tracks northeastward across Arizona. The next opportunity for precipitation will be Tuesday night into Friday morning as a more significant weather system from the Pacific approaches and then moves through the state. The best chances for precipitation will be Wednesday and Thursday. The system will also bring cooler temperatures and breezy to windy conditions at times.
Peak 8 hour average Ozone values each day are expected to remain in the Good range thanks to the time of year, good to excellent ventilation and enhanced cloudiness over the next several days.
