Forecast Discussion:
Showers this morning may stabilize delay the onset of afternoon thunderstorm activity but otherwise anticipate at least isolated coverage over southern Coconino County later today and again Wednesday. A downtrend then begins with only a slight chance of thunderstorms Thursday through Saturday but with an increase in temperatures.
Peak 8 hour average Ozone is expected to be in the upper Good range today and Wednesday then climb into the Moderate category reaching the upper part of the range by Saturday.
