.DISCUSSION...

Light south to southwest winds become variable at times, contributing
to poor to fair smoke dispersion. Increasing moisture will allow for
scattered afternoon showers and storms in vicinity of the burn site.
Storm movement will be slow and erratic at times, and slow moving storms
have the potential for locally heavy rainfall. There are no critical RH
concerns. High temperatures will reach the mid 90s with peak heat index
values near 105 degrees.
