FORECAST SUMMARY:
Monday, August 12th, 2019 through Friday, August 16th, 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:
A frontal boundary and associated low pressure area will bring precipitation in the forecast later Monday into Tuesday. Then, a second weaker system could trigger scattered precipitation later Wednesday. These systems should keep ozone primarily Good through mid-week. Northerly winds at upper levels then keep cooler temperatures around through Friday. Conditions dry out Thursday and Friday, but lower temperatures will keep ozone from increasing higher than a few Moderates. Moderate fine particulate in the southeast Monday into Tuesday will likely improve to Good by Wednesday, lasting through Friday.
EXTENDED FORECAST:
Extended models are hinting at a warmup for the coming weekend which could make increased ozone a possibility. There is a bit on uncertainty; therefore, this forecast will be updated Friday to detail weekend air quality conditions.
