Expect another day of record temperatures before a change in the weather pattern begins over the weekend and continues next week. The change in the pattern will lead to a cooling trend, stronger daytime winds, more cloudiness, and rain chances (starting Sunday).
Peak 8 hour average Ozone is anticipated to remain in the upper part of the Good range but will be close to the Moderate threshold.
