.WHAT HAS CHANGED...
Let the heat advisory expire.

&&

.KEY MESSAGES...
1) Isolated to scattered thunderstorms this evening into the
overnight.

2) Scattered storms will develop again Sunday and Monday. Temperatures
will return to near normal levels.

&&

.DISCUSSION...
KEY MESSAGE 1)
Much of the thunderstorm activity has been centered near the I-70
corridor. Additional thunderstorms have developed across Indiana and
will work into portions of the region a well. Additional storms have
developed south the region and have the potential to move into
southern portions of the region. Not all locations will receive rain
however with storms being scattered in nature.

While widespread severe weather is not expected, isolated strong to
severe storms will still be possible. In addition, these storms will
produce heavy downpours and could lead to localized flooding issues.

KEY MESSAGE 2)
Sunday into Monday, a weak mid-level disturbance will slowly shift
east through our area with showers and storms possible each day.
Instability will be much less as winds shift to the north behind a
weak frontal boundary. This will limit the severe storm threat.

&&

.AVIATION /00Z SUNDAY THROUGH THURSDAY/...
Scattered showers and some thunderstorms will be around this evening
and the first part of the overnight hours. Timed in at TAF sites
based on highest probability of occurrence. Overnight, there will be
the potential for some MVFR cigs and vsbys. Additional cu and
thunderstorms will develop for Sunday.

Outlook...Thunderstorms possible through Monday and then again on
Thursday.
