08/16/2019 Forecast Update
FORECAST SUMMARY:
Friday, August 16th, 2019 through Monday, August 19th, 2019
Ozone: 8-hour Ozone concentrations will range from Good to Moderate through the forecast period.
PM-2.5: 24-hour Fine Particulate concentrations will range from Good to low-Moderate.
FORECAST DISCUSSION:
Systems will bring on and off chances for precipitation through the weekend. The first chance will be Friday evening/night; Saturday should be mostly dry; but precipitation chances return Sunday. A stronger front moves through later Monday/Tuesday cooling conditions down by mid-week.
As for air quality, seasonable surface temperatures, coupled with cooler upper level temperatures and at least scattered cloud cover, will keep ozone from reaching higher than Moderate Friday or Saturday. By Sunday, surface and upper level temperatures increase along with dew point readings. Clouds and precipitation associated with a system nearby should again keep ozone from reaching higher than Moderate. Less cloud cover is expected Monday with warmer temperatures continuing; however, the system passing through Sunday should allow for more northerly/westerly winds. Currently, ozone is not expected to get higher than Moderate on Monday.
Significant build-up of fine particulate is not anticipated. Readings should range from middle Good to low Moderate.
EXTENDED FORECAST:
Extended models show cooler conditions by mid-week allowing for Good air quality.
