2) A low pressure system brings the chance for precipitation and
colder temperatures for the end of the week.

.DISCUSSION...
KEY MESSAGE 1...

Dry conditions are expected for the next 24 hours ahead of a more
active pattern starting Wednesday evening. This afternoon, a dry
cold front has been working through northern Ohio, and is roughly in
line with the I-70 corridor as of this writing. Light northwest
winds are observed in west-central and central Ohio with
southwesterly winds observed in eastern Indiana and southwest Ohio.
1
The front will stall later this evening, allowing winds to become
light and variable. Widespread fog is not currently expected, but the
stalled front and clear skies do support the potential for radiation
fog late tonight into Wednesday morning. The dry conditions
associated with the front are a limiting factor and likely prevent
this from being a widespread issue.

KEY MESSAGE 2...

As the low pressure approaches the area tomorrow, clouds will
increase in coverage, especially into the late afternoon and evening.
A band of showers and perhaps a few rumbles of thunder move into
southwest portions of the area during the evening hours. Ahead of
this band, a few showers may pop up along the stalled front, which is
still expected to be along and north of the I-70 corridor. Forecast
soundings show a very narrow CAPE area for only a few hours across
portions of southwest Indiana and western Ohio so thunder mentions
are very limited within the forecast. Due to the later timing, the
severe threat appears lower at this time. If the timing moves closer
to the early evening, a few strong wind gusts would be possible in
southeastern Indiana (SPC Day 2 Marginal Risk).

Otherwise, slow moving showers along the front combined with the band
of rain provide some potential local rainfall amounts to be between
0.50-1". Most locations see less than 0.50".

Wednesday night, the low pressure deepens as it shifts east out of
the region. While not during an optimal diurnal window, the pressure
response on the backside of the low pressure may result in a period
of gusty winds overnight into early Thursday morning. Most gusts
should peak in the 30 mph range, but a few gusts up to 35 mph are
possible.

From Thursday through Saturday, deep cyclonic flow is persistent over
the region. Expect below normal temperatures, widespread cloud
coverage, and northwesterly flow. Precipitation chances are highest
on Thursday, and there may be enough cold air to produce the first
flakes of the season.

Temperatures gradually begin to climb back into the 50s early next
week, remaining a few degrees below normal.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
Prevailing VFR conditions through the TAF period, however, there is
some potential for fog developing late tonight into Wednesday
morning. A weak front moves into the northern TAF sites
(DAY/CMH/LCK) this evening, stalling overnight. Conditions have been
dry throughout the day and the front is cloud free, but the calm
winds and clear skies may help to favor fog development overnight.
For now, have TEMPO MVFR for DAY/ILN/CMH/LCK for this. Otherwise, the
typical valley fog potential is mentioned at LUK.

Southwest to northwest winds this evening become light and variable.
Light winds likely continue through the morning and early afternoon
hours across DAY/CMH/LCK, but they will also eventually become
southerly. Wind speeds remain 10 knots or less.

OUTLOOK...MVFR to IFR ceilings and visibilities possible Wednesday
night through Friday.
