| A temporary relief from this week's hot
temperatures will follow a cold front expected to cross Oklahoma tonight.
Temperatures will be less hot this weekend, as a dry air mass settles over
the state. These conditions, combined with clear skies, will support ozone
formation statewide, with the potential for ozone concentrations to approach
the "Unhealthy for Sensitive Groups"/Orange category on Sunday and
Monday around the OKC and Tulsa metros. Simultaneously, the influx of
northern air will carry smoke into the state, keeping particulate matter
concentrations in the Moderate/Yellow category. |
