.SYNOPSIS...
Showers and thunderstorms will be possible today in advance of a
cold front. Precipitation will come to an end for Tuesday evening and
fog will be possible across portions of the region for Tuesday
night. After a brief moderation in temperatures, warmer temperatures
will start to work back into the region into the weekend.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
One area of precipitation across eastern portions of the region has
decreased in coverage and moved out of the region. There is then a
lull in the precipitation and also breaks in the cloud cover. Due to
this have some patchy fog mention in. There are already some showers
starting to develop across the Tri-State in advance of a larger area
of showers and thunderstorms over Indiana. Expect additional shower
and some thunderstorm activity to move into the region later in the
overnight and into the day on Tuesday. Cannot rule out an isolated
strong to severe storm with damaging winds the primary threat across
primarily the southern and southeastern portions of the region today.
In addition pockets of heavier rainfall will lead to the potential
for localized flooding issues. A cold front will move through late in
the day. Temperatures will be cooler today with highs in the low to
middle 80s.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/...
Cold front will continue to move through during the evening.
Precipitation will quickly come to an end. While drier air will start
to work in there will be some lingering low level moisture and
therefore have patchy fog in across the southeastern half of the
forecast area primarily near and southeast of Interstate 71. Also
have patchy dense fog in the river valleys.

Temperatures on Wednesday are expected to be in the low to middle
80s with dewpoints in the 60s.  CAA cu will be present.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
On Wednesday evening, an area of surface high pressure will be
centered over the middle Mississippi Valley region, extending
northeastward into the Ohio Valley. The upper level pattern will
exhibit troughing over the northeastern states and Quebec, and
ridging building into the central part of the CONUS.

The ridging will begin to move east through the end of the week and
into the weekend. This will put the ILN CWA into a pattern that will
trend warmer with time. Conditions look to be generally dry, with
the area a little too close to the center of the ridge (and the
associated surface high) to be in a favorable location for storm
development. Could probably be a very low chance of some showers and
storms in northern Indiana and Ohio on Thursday and Friday, but
chances in the ILN forecast area would be very low confidence at
most. Dry weather is now forecast for Saturday as well, with the
ridge remaining well-established. Since precipitation will not be
the main concern through this period, a return to hot temperatures
may be the bigger issue -- with highs reaching the lower 90s by
Saturday. As of now, it looks like dewpoints may stay low enough to
keep the area out of heat advisory criteria.

By Sunday, there is more variance from model-to-model, but some
signs that the ridge may begin to break down a bit as a shortwave
approaches from the west. Chances for thunderstorms look perhaps a
little higher for Sunday and Monday, but confidence remains low in
any specifics. Temperatures should stay warm on Sunday (lower 90s)
before starting to fall slightly early in the week (upper 80s on
Monday). While chances for storms will exist for Sunday and beyond,
as of now, no clear signs for organized convection or significant
hazards through the extended forecast period.

&&

.AVIATION /10Z TUESDAY THROUGH SATURDAY/...
An area of showers and some embedded thunder continues to move across
the region. Showers and some thunderstorms will be possible into the
early afternoon hours. MVFR cigs and vsbys will be possible at times
with this area of precipitation. There will then be a brief lull or
decrease in activity before the cold front moves through later in the
day. Have one or two hours of showers with that feature. There will
be several wind shifts through the TAF period. Skies will start to
clear out at the end of the TAF period and have some fog developing
during that time.

OUTLOOK...No significant weather is expected at this time.
