.DISCUSSION...
KEY MESSAGE 1)

Have observed scattered nocturnal convection across portions of
southern Illinois and southern Indiana the last few hours. This is in
response to increasing moisture and elevated instability within an
area influenced by a low level jet. This activity, and possibly new
activity within this zone, may skirt the southwest portion of our CWA
early this morning. There is some uncertainty how far north
convection will form, but have chance PoPs including most of
southeast Indiana and northern Kentucky before the chance for
convection sharply cuts off to the north early this morning.

After a mid morning to early afternoon lull, new convection is
expected to form by late afternoon. While there is uncertainty as to
how much coverage there will be due to weak forcing, the most likely
location for convection looks to be across eastern Indiana into
west/southwest Ohio. Assuming better moisture return in the low
levels and sufficient instability, isolated strong to marginally
severe storms will be possible, with the primary threat strong to
locally damaging wind gusts. Convection may move east into central
Ohio during the evening before dissipating.


KEY MESSAGE 2)

A shortwave trough digs into the Midwest and Great
Lakes Tuesday into Wednesday. At the surface, a cold front moves
south into the CWA on Tuesday, gradually moving through Tuesday night
into Wednesday. This will provide a chance of showers and
thunderstorms during this time. Initially, timing could be a little
tricky, as some guidance suggests even some morning convection on
Tuesday, but the majority of the showers and thunderstorms will be
likely to occur from Tuesday afternoon through Wednesday morning.
During this time, it is likely that much of the area receives 1 inch
of rainfall, with a low probability that some locations could reach
2 inches of rainfall. Will have to monitor for any potential hydro
issues on small streams/creeks, but at this time the risk for
flooding appears to be low.

Even with the cold front residing to the south by late Wednesday,
influence from the mid level trough will keep unsettled conditions
(showers) in the forecast through the rest of the week, along with
below normal temperatures.

.AVIATION /10Z MONDAY THROUGH FRIDAY/...
There may be a passing shower which impacts the KCVG/KLUK terminals
early this morning, otherwise expect VFR conditions with primarily
mid clouds for the balance of the morning. By late afternoon,
scattered convection is expected to develop. There`s uncertainty with
how much coverage there will be, however KDAY/KILN may have the best
chances, at least initially, to be impacted by a storm. Confidence
further east toward Columbus during the evening is lower.

Southerly winds are expected to become gusty late this morning into this
afternoon, and may remain gusty at or above 20 knots this evening.
Non-convective low level wind shear may also develop late tonight.
The majority of overnight showers and thunderstorms are expected to
remain to the northwest.

OUTLOOK...Thunderstorms possible Tuesday afternoon into Tuesday night.
MVFR to IFR ceilings and visibilities likely Tuesday night into
Wednesday.
