.DISCUSSION (This evening through Thursday)...
Issued at 238 PM EDT Thu Jul 9 2026

Satellite imagery depicts a well defined MCV near St. Louis
progressing eastward. This will likely be the main source of lift
this afternoon and evening, with an MCS likely developing over south
central IL after 4PM. Model guidance is still widely varied on
specific placement of this MCS, but given MCV and LLJ placement, the
current expectation is for this MCS to move through far SW portions
of central Indiana between 7-11PM this evening. Sounding analysis
shows a quasi-inverted "V" sounding in the lowers 1km of which is
allowing for 1000+ J/kg of DCAPE. This should allow for micro-scale
bowing segments along the cold pool, with a damaging wind gust
threat during this same time period. Within any organized segments,
a weak tornadic spin up is possible but given LCL height and weak
boundary layer shear, this threat should remain very isolated.

The next threat tonight will reside with the potential for a remnant
boundary to develop following the passage of the MCV. This boundary
coupled with a consistent 30-40kt LLJ could lead to training
convection south of a Bloomington to Columbus line between 02-08Z
overnight. If this does occur pockets of 2-4" over a 6 hour period
will be possible, with localized flooding threat. As the LLJ weakens
tomorrow morning, convection will eventually dissipate, with most
areas becoming dry by 10Z.

Friday through Saturday:

Another upper level wave will move slowly through the region Friday
into Saturday with a weak surface boundary expected to pass from
north to south through central Indiana during the afternoon and
evening. Models are starting to come to a better agreement on
timing, with convection likely to occur between 4PM and 10PM from
north to south across the region. Shear will be rather weak this
time around, and therefor the severe risk is low for Friday. That
said, there is enough destabilization through a deep saturated
column for an isolated wet microburst to be possible. A quick inch
is possible over a 30min period with these storms as well, but the
movement on these cells should be fast enough to limit the flood
threat for the afternoon and evening hours.

Late tomorrow evening, this boundary is expected to stall near or
south of central Indiana, with another nocturnal LLJ expected to
form. If this boundary stays within central Indiana, there is some
potential for an additional flooding concern Friday night, but
confidence is low on this occurring at this time.

Sunday through Next Week:

The strong upper ridging centered over the Rockies during the second
half of the weekend will shift east into the Mississippi and Ohio
Valleys for much of next week bringing a return to a warmer and
drier pattern for central Indiana. Highs will return to the upper
80s and lower 90s through the middle of next week. Unlike the recent
high heat in late June and the first few days of July...temperatures
and dewpoints should be lower through the period which will keep
heat indices largely manageable from a heat stress standpoint...
peaking in the mid and upper 90s.

A few lingering storms are possible Sunday over southern counties as
an upper trough axis shifts away to the south The presence of a
strong mid level cap will largely mitigate convective risks from
late Sunday through Tuesday. By Wednesday and Thursday...mid level
temperatures will fall weakening the cap with a greater opportunity
for isolated convection focused largely during the afternoon and
evening. A more pronounced threat for thunderstorms will come late
week into next weekend as the ridge suppresses and a cold front sags
south from the Great Lakes. In the wake of this frontal passage...a
cooler airmass will expand into the region.

.AVIATION (18Z TAF Issuance)...
Issued at 135 PM EDT Thu Jul 9 2026

Impacts:

- Showers and storms possible at all sites this evening into the
  overnight

Discussion:

VFR conditions will remain throughout the afternoon into the
evening. After 22Z, a MCV will push into Indiana with a broken line
of thunderstorms expected at KHUF and KBMG through 02Z. A remnant
boundary behind this MCV coupled with a LLJ will likely lead to
additional thunderstorms between 02-08Z overnight. Greatest threat
will be at KBMG, but all sites could see a thunderstorm.

MVFR ceilings could be possible tomorrow morning, but confidence
is low.

Winds will be light out of the southwest(200-230 degrees) during the
day, becoming variable after 00Z as the MCV pushes through.
