.SYNOPSIS...
An upper level disturbance will bring thunderstorms and the potential
for damaging winds today. A cold front will move through Monday night
into Tuesday bringing with it additional thunderstorm chances. Dry
conditions will be present for Wednesday before a weaker system
brings some additional precipitation chances for Thursday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
A disturbance moving through this morning will continue to bring
showers and thunderstorms to the region. A stronger disturbance moves
through later in the day bringing with it additional thunderstorm
chances. Will continue to highlight the potential for damaging winds
in the HWO. In addition will continue to mention the potential for
isolated flooding as well.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM TUESDAY/...
The cold front will work through tonight into Tuesday. This will
bring with it additional thunderstorm chances until the passage of
the frontal boundary. Cannot rule out an isolated strong to severe
storm on Tuesday as well. The best chance for this would be across
southern and eastern portions of the forecast area. Will mention
isolated potential in the HWO.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
On Tuesday evening, a cold front will have just cleared through the
ILN forecast area, and will continue to move east. Behind the front,
surface high pressure -- and a cooler and drier air mass -- will
settle into the region. This will lead to quiet weather conditions
Tuesday night through Thursday morning.

By Thursday, there will be a slight shift to the weather pattern, as
troughing develops over the northeastern states, and ridging
develops through the central part of the CONUS. A weak shortwave in
the northwest flow may bring some precipitation to northern Indiana
and northern Ohio on Thursday afternoon.

By Friday, the surface high will be moving further to the east, and
the ridging over the central CONUS will begin drifting eastward as
well. This will place the Ohio Valley in a warm advection pattern
through the weekend, which will allow both heat and humidity to
gradually increase. In terms of temperatures, highs in the lower 90s
can be expected on Saturday and Sunday as well. As temperatures
increase, chances for precipitation will begin to increase again as
well -- just a little bit on Friday, and then with greater chances
on Saturday and Sunday. While chances for storms will increase, as
of now, no clear signs for organized convection or significant
hazards through the extended forecast period.

&&

.AVIATION /10Z MONDAY THROUGH FRIDAY/...
An area of showers and isolated thunder is moving into the western
TAF sites KCVG, KLUK, and KDAY. Additional shower and thunderstorm
development is expected through the day. Precipitation will decrease
in coverage overnight tonight before picking up near the front during
the day on Tuesday at the longer KCVG TAF.

Cigs will be a mix of MVFR and VFR. Cannot rule out briefly lower
cigs, however in general most will be VFR or MVFR. There will be the
potential for fog in spots tonight.

OUTLOOK...Thunderstorms possible on Tuesday.
