Forecast Discussion: Another area of low pressure in the area will result in shower and thunderstorm activity Friday, mainly this afternoon. Convection will begin too early for ozone to get elevated to the moderate range. Following this, an east to northeast flow will commence on Saturday behind a back door cold front, which will mean another day of good air quality. Ozone levels will then rise by the early part of next week as the overall air mass over us stagnates with a fair amount of sunshine and warmer air.
