.SYNOPSIS...
High pressure will allow for dry conditions through the day on
Wednesday. A system will then bring rain to the region Wednesday
night into Thursday. An active pattern will continue into the weekend
with multiple rounds of precipitation.

&&

.NEAR TERM /THROUGH TONIGHT/...
Widespread cloud cover is expected through the afternoon. There is
some question with how quickly the clouds start to move out or
dissipate. Typically they hold on a little longer this time of year
and slowed the decrease in clouds in the forecast. Once they do
expect some fog. There will likely be a fog and stratus combination.

There will be a wide range in low temperatures overnight with lows in
the upper 20s north of Interstate 70 and upper 30s across northern
Kentucky.

&&

.SHORT TERM /WEDNESDAY THROUGH WEDNESDAY NIGHT/...
WAA will allow for temperatures to reach into the 50s across the
tri-state on Wednesday. It will take longer for temperatures to rise
across the rest of the area with highs only in the 40s expected
during the day on Wednesday. Temperatures will continue to rise
overnight Wednesday night. Rain will overspread the region Wednesday
night.

&&

.LONG TERM /THURSDAY THROUGH MONDAY/...
A warm weather pattern persists through the week before breaking on
Sunday. For Thursday, a stalled front is likely to be draped across
the area. Locations north of I-70 may remain in the upper 40s/lower
50s while locations south of the Ohio River may reach 60. Rain
chances exist with the front in the area and a possible upper level
shortwave trough moving through.

The aforementioned stalled front lifts north of I-70 Thursday night
into Friday when a weak surface low moves across the area. Rain
chances exist along the front when it lifts north as a warm front.
Some low end shower chances may persist in the warm sector on
Friday. Forecast highs are in the 60s for most locations. Warm
conditions continue on Saturday. Forecasts highs once again reach
into the 60s for most locations.

On Sunday, the synoptic setup may change. A strong cold front is
currently forecast to push through the area dropping temperatures
and dew points significantly. Windy conditions accompany the arrival
of the cold air on Sunday into Monday. Rain will likely accompany
the front.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
Widespread MVFR cigs are currently across the TAF sites. Expect these
cigs to continue until at least this evening. There is some question
on how quickly these cigs will dissipate and they typically hold on
longer this time of year. Linger them longer at KCMH and KLCK. If
they start to break up quicker this evening there will likely be more
fog and if not then the MVFR to IFR cigs will be more of a concern.
There will most likely be some combination with a stratus and fog
setup at times overnight. Have the MVFR cigs and vsbys lasting well
into the day on Wednesday at KCMH and KLCK.

OUTLOOK...MVFR to IFR ceilings and MVFR visibilities likely
Wednesday night into Thursday with MVFR ceilings possibly lingering
through Sunday.
