Isolated showers and thunderstorms may begin developing near the burn site towards the noon hour, followed by increasing chances for showers and thunderstorms throughout the afternoon hours. Westerly surface and transport winds will prevail this morning, with surface winds shifting to southwesterly outside of thunderstorm activity this afternoon. Heat index values will again approach Heat Advisory criteria by early afternoon before showers and thunderstorms increase in coverage. Gradually strengthening transport speeds and elevated mixing heights will result in good daytime dispersion values. Showers and thunderstorms will diminish in coverage towards sunset, with west-southwesterly transport winds only gradually diminishing overnight tonight. .REST OF TODAY...
