| Warm temperatures and stagnant flow
associated with a weak stationary boundary will foster ozone development into
the Moderate Category through midweek with metro areas and northwestern
Oklahoma seeing the highest amounts. Pop-up showers and thunderstorms are
forecasted across the state during evening/nighttime hours through Friday.
Any area that sees one of these slow-moving storms will experience a
temporary washout of ozone and particulates. Flow will switch to a stronger
southerly pattern on Friday, likely pushing any remaining ozone accumulation
out of the area. |
