.DISCUSSION...
1. Hot and muggy conditions continue for most of the week,
but subside just enough that no heat advisory is necessary for
Tuesday. A pattern change may be in store for this weekend.
2. Following a few days of suppressed convection, diurnal showers
and thunderstorms return by Thursday and persist through the
weekend. A cold front may further enhance storm activity over
the weekend.
