.DISCUSSION...
KEY MESSAGE 1)
Issued a flood watch for areas that have received heavy rainfall in
recent days and also are expected to get additional heavy rain into
tonight. This combination is over portions of northern Kentucky and
into portions of southern Ohio. Precipitation will gradually start to
diminish overnight. Precipitation on Monday and Tuesday will be more
limited and primarily near and south of the Ohio River. There will be
additional precipitation chances for Wednesday primarily focused
south of I-70. Drier conditions are expected for Thursday and Friday.
There is more uncertainty with model variability going into the
weekend on precipitation chances.

KEY MESSAGE 2)
High temperatures will be in the 70s to low 80s over the next week
and lows will generally be in the 50s to low 60s for the week. These
values are near normal for a lot of the week, however Tuesday through
Thursday will have a better chance of being slightly above normal for
temperatures.

&&

.AVIATION /00Z MONDAY THROUGH FRIDAY/...
Majority of showers have pushed east of the terminals this evening.
There is still a weakening line of showers west of KCVG/KLUK and KDAY
that could result in a brief -SHRA. Otherwise, main impacts tonight
will be some IFR/LIFR CIGs, along with MVFR/IFR vsbys. Guidance
pretty set on IFR CIGs developing, but some locations such as KILN
may deal with LIFR and perhaps even VLIFR CIGs for a period
overnight.

The trapped shallow moisture will result in some BR development. Most
of the guidance keeps reductions IFR at worst for BR.

CIGs will likely be slow to improve Monday morning, so maintained
MVFR through at least noon. Expecting improvement back to VFR during
the afternoon.

OUTLOOK...Thunderstorms possible Wednesday.
