  with all severe hazards possible. Damaging straight-line winds are
  the main hazard, but a few tornadoes and large hail will be
  possible. Localized heavy rainfall may lead to flash flooding,
  especially east of I-65.

  through Friday this week.

* Rain chances return late week into the weekend with maximum
  temperatures returning to the 90s.

.UPDATE...
Issued at 341 PM EDT Tue Jul 21 2026

Semi-discrete supercells have now congealed into a squall line
moving through south-central Indiana and into central Kentucky.
Forecast updates reflect the timing of the system, which is
closely mimicking the HRRR forecast. SPC mesoanalysis ahead of
the squall line has very high CAPE (instability) amounts (SBCAPE
upwards of 4000 J/KG, MLCAPE around 3000 J/KG), effective bulk
shear between 40-50 KTS, PWs of greater than 2 (approaching
climatological maximum for July), DCAPEs greater than 600 J/KG, and
registering elevated numbers on several supercell/tornado
parameters (supercell composite, effective layer STP, effective
layer SRHs). Storms will continue to race toward the
south/southeast direction into a ripe environment for storms to
continue and/or strengthen for the next 4-6 hours.

.SHORT TERM /THROUGH TONIGHT/...
Issued at 145 PM EDT Tue Jul 21 2026

*** Today and Tonight ***

An upper level trough is beginning to drop south into the northern
part of the Ohio Valley. An associated low pressure system over
Ontario is draping a cold front SW through northern IL into the
Central Plains. This front is expected to push through the forecast
area today and tonight. Ahead of the line, PWATS are between 1.5" to
2" across the region (on the order of 75th to 99th percentile for
late July). As storms start to move in this afternoon, PWATS could
reach 2.5" (approaching climatological maximum for late July).
Southern IN counties can expected for storms to start moving in
early afternoon, with a some more discrete storms initially. As the
afternoon progresses, a broken line of storms will beginning to
develop over southern IN and move SW through KY.

All severe threats remain possible for this afternoon and evening.
Gusty winds up to 70 MPH are expected with storms, along with a 1"-
2" hail threat. Isolated large hail is not out of the question, but
has the greatest chance with discrete cellular storms rather than
with the linear convection. A few isolated tornadoes are possible
mainly east of I-65, but not off the table for the remaining of the
forecast area. SBCAPE values are ranging from 2,000 - 4,000 J/kg
across the area providing ample instability for the environment.
Deep layer shear values of 30 - 40 kts are also expected to move in
ahead of this line, adding to the threat of tornadoes. However, LCL
heights are expected to remain marginal which would decrease that
threat slightly. There is also a concern for flash flooding with the
favorable PWAT environment. Storms will produce heavy rainfall
leading to isolated flash flooding, along with any training storms
through the evening hours. A flood watch has been issued for KY
counties mainly east of I-65 that will run through late tonight.

.LONG TERM /WEDNESDAY THROUGH TUESDAY/...
Issued at 145 PM EDT Tue Jul 21 2026

*** Tomorrow - Monday Night ***

Behind the cold front, a surface high pressure will build into the
Ohio Valley starting tomorrow. The upper level ridge that is
currently in place over the southern Plains will continue to
persist, leaving the Ohio Valley region in a northwesterly flow
aloft. Tomorrow some gusty winds are possible through the day as a
mid-level jet moves through. Maximum temperatures tomorrow are
expected to be in the mid to low 80s tomorrow with the CAA behind
the front. Temperatures will bounce back to the mid to upper 80s by
Saturday.

The next chance for precip will be Friday as a shortwave
trough moves east from the Central Plains. As we move into the late
weekend early week, a couple frontal boundaries will move through
the region. This will likely bring another round of rain showers for
Sunday into Monday. Temperatures to start the week will be in the
upper 80s and low 90s.

.AVIATION /18Z TAFS THROUGH 00Z THURSDAY/...
Issued at 145 PM EDT Tue Jul 21 2026

Convective activity over south central Indiana has initiated and
is starting to move southeastward into the region. General
arrival times are between 18Z and 19Z for south central Indiana
terminals, 19Z and 20Z for Louisville area terminals, and
pushing into central Kentucky (including Lexington, Bardstown,
Elizabethtown areas) for 20Z to 21Z. Sites should expect a few
hours (at least) of strong gusty winds and reduced visibilities
from heavy downpours this evening. Hail is also a concern in
these storms. Once storms pass, general wind direction will be
out of the NW with some chances for patchy MVFR fog later
tonight into tomorrow morning.
