What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Indianapolis, IN wrote its last area forecast discussion before this severe thunderstorm warning went out at Apr 5, 12:11 PM EDT, 17 minutes earlier.

Area forecast discussion, Apr 5, 12:11 PM EDT, 17 minutes before
Area Forecast Discussion
National Weather Service Indianapolis IN
1211 PM EDT Wed Apr 5 2023

.Mesoscale Update...
Issued at 1211 PM EDT Wed Apr 5 2023

Primary area of concern over the next 1-2 hours will largely be
confined to a couple of small bowing segments on the northern edge
of the ongoing broken convective complex along and ahead of the
approaching cold front, with the majority of the line pushing
through north and west central Indiana appearing likely to remain
mostly sub severe with gusts in the 40-50 MPH range. Cannot entirely
rule out brief intensifications of the line further south in the
area, but increasingly expansive cloud cover over the region is
suppressing insolation and eroding instability across the area, and
thus expect that the convective line will continue to struggle as it
moves eastward.

There will remain at least a modest threat for rapid mesovortex
generation and possible brief and weak QLCS tornadoes, given the
potent magnitude of the 0-3KM shear (40-50KT), although orientation
of the shear vector is largely line parallel, particularly southwest
of Indianapolis, and will require reorientation of the QLCS
convergence zone via surges or small bows to realize the effect of
aforementioned shear.

The magnitude of the overall flow in the low to mid levels (KIND VWP
sensing 50-65KT in the 2-6KM layer) will continue to support
isolated damaging wind gusts being forced to the surface via
downdrafts, and latest ACARS sounding out of IND does show slightly
more dry air in the lowest 3KM and thus some slightly enhanced
evaporative cooling/downburst potential, but the continued erosion
of instability over the area as temperatures cool should maintain a
limit on a more widespread and significant damaging wind threat.

Expect that this line will bring our threat to an end by the time it
exits the area around mid afternoon, although a more significant
threat may evolve to our south and east later today along and ahead
of the frontal convection in areas where clearer skies have allowed
for more significant warming thus far today.

Previous Mesoscale Update Issued 1057 AM EDT April 5 2023

Current analysis of ongoing and expected convection for the next
couple of hours across Central Indiana... Early morning convection
seems to have somewhat stabilized the atmosphere, with satellite
imagery indicating horizontal features that are not growing
vertically rather lifting perpendicular to the approaching
convective line upstream in Illinois. Latest aircraft soundings
indicate the earlier dry layer at 850mb has moistened, likely a
result from recent convection and some earlier moisture convergence.
The winds from the sounding also support less backing in the low
near surface environment, and has become more uniform within the
lowest 3km of the atmosphere. There still does appear to be some
speed shear between 20kt to 50 kts, so any stronger more vertically
developed convective elements could still produce gusty winds to
near severe limits.

But the next challenge will be on the approaching line of
convection, which is presently in Northwest Indiana or Lafayette to
Gary, extending southwest through Central and Southern Illinois.
This line will continue to push east late this morning, but given
the recovering environment ahead of the line, this seems to be
favorable for seeing smaller convective elements lift perpendicular
to the line. This becomes the concern for the potential of weaker
meso circulations to quickly develop and produce weak tornadoes
associated with the QLCS like structure...main timing appears to be
late morning into early afternoon, but the threat will enhance as
the day progresses for areas east of the convective line.

&&

.Short Term...(Today and tonight)
Issued at 256 AM EDT Wed Apr 5 2023

Severe thunderstorms are possible today, although there are some
negative factors for significant/widespread severe. Damaging
winds and a few tornadoes are still possible. Hail is more
conditional and should generally be limited in size and impact.
Any significant severe should be localized, conditional, and
dictated by the storm scale or mesoscale. Meteorological analysis
and range of possibilities are covered in the analysis below.

There has been a sizable shift in the character of the upstream mid-
latitude cyclone in model data over the last few days. Early
indications were a quicker lower amplitude scenario with jet exit
region breaching the warm sector at a more orthogonal angle,
resembling some of the more classic dangerous tornado scenarios of
the past somewhere across the region. But the trend has been slower
and more amplified with key elements for a significant larger scale
tornado event now absent.

Water vapor channel imagery shows an amplified trough centered
roughly over the Rockies with deepening closed low over the eastern
Dakotas. Models have the midlevel speed maxima downstream of the
trough axis, and the strongest synoptic-scale ascent in its exit
region shifting quickly into Canada today. The cold front will tend
to outpace the trailing weakly cyclonic but intense midlevel flow
and associated DCVA, and should be the primary forcing mechanism for
convection in our area today. It should cross through during the
afternoon, interacting with a deep subtropical plume of mid-high
level moisture from the east Pacific that is clearly seen in CIRA
layered moisture products spreading into the Ohio Valley. Within
this deep moist plume, weaker midlevel lapse rates are present, and
will likely limit destabilization somewhat. Nevertheless, at least
modest instability will exist and in the presence of strong mass
response (i.e., ~50+ knot low level jet) causing strong shear, will
result in some severe thunderstorm potential.

The coverage of convection may be high, resulting in complicated
storm scale interactions and mergers, and limiting the opportunity
for discrete storms. A QLCS forced/maintained by frontal convergence
may be the most noteworthy convective feature for our area. However,
satellite-derived layered moisture products show a pronounced
northward surge of deeper low-level moisture in the central gulf
coast states, helping to increase convective coverage over Arkansas.
This is ahead of frontal forcing. The expansiveness and magnitude of
this convection is currently in question, but it is occurring within
a low-level warm/moist advection regime and within aforementioned
mid-high level subtropical moisture plume. So, it should maintain in
at least limited coverage. This could move into southern and
portions of central Indiana during the early morning hours,
preceding the frontal QLCS.

Expected/possible scenarios with regards to convective evolution:

1. There could be just enough height falls/ascent, midlevel cooling,
and low-level warm/moist advection for pre-frontal convection to
increase early-mid morning. This would primarily be over the
northwest half of Indiana, and seems low probability at this time.
If it occurred, a marginal hail/wind threat could evolve, but
diurnal minimum coupled with moistening/warming trend in the mid
levels should preclude a more substantial threat.

2. Convection now in south-central Missouri and north-central
Arkansas continues northeastward reaching southwest portions of
the area by around 6am or shortly after. Parameter space would
support a marginal hail/wind threat as well, but it may not be
fully rooted in the boundary layer.

3. QLCS maintains and even reinvigorates some as it moves into
central Indiana late morning through early afternoon and interacts
with deep moist axis and modest diabatic surface heating. Shear
vector orientations will be oblique, but sufficient in magnitude
for some concern with localized surges and line reorientations
supporting mesovortices and a few tornadoes. Otherwise, deep moist
environment and water loading amidst at least modest instability
will result in wind as the primary threat. The storm mode should
limit or preclude the hail threat.

Tight MSLP gradient and at least some mixing and momentum
transfer could result in wind gusts at least approaching Wind
Advisory criteria, albeit not as significant of a threat as the
last two mid-latitude systems. We will continue the Windy
Advisory, though it is low confidence relative to the previous two
cases. Post-frontal gradient will be less than previous system as
well, given the higher latitude track. Stronger winds aloft pass
during the diurnal mixing minimum tonight, limiting potential for
substantial wind speeds.

&&

.Long Term...(Thursday through Tuesday)
Issued at 256 AM EDT Wed Apr 5 2023

A quiescent synoptic pattern evolves in the long term period with
stronger westerlies aloft relegated to higher latitudes and positive
midlevel height anomalies dominating south of that. Post-frontal
cold advection Thursday is modest and temperatures should be only
slightly below early April climatology. A steady day to day warm-up
is expected into early next week as midlevel heights become more
positively anomalous. One weak perturbation over the Great Lakes by
Monday is less pronounced than previous runs with minimal ascent
interacting with a continental air mass. Deeper moisture at that
time will be confined to the gulf coast region. Thus, precipitation
seems unlikely. In its wake, an impressive plume of well mixed and
adiabatically warmed air aloft originating in the semi-arid
southwest will help us rise to well above climatology for what looks
to be the majority of next week. Temperatures may reach the 80s by
midweek, and dry conditions look to prevail.

&&

.Aviation...(12Z TAF Issuance)
Issued at 611 AM EDT Wed Apr 5 2023

Impacts:

* Low level wind shear this morning

* Thunderstorm window 14-20z

* MVFR stratus with rain/storms

* Strong gusts up to 35-40 knots outside of storms before the front

Discussion:

Poor flying conditions are expected today with deteriorating
ceilings, increasing storm coverage, and strong winds. Thunderstorms
over southern Illinois should impact at least BMG and possibly IND
and HUF early-mid morning, and additional storms along the front
will reach all TAF sites by midday and exit later this afternoon.

Generally improving conditions are expected mid-late afternoon with
departing rain and storms, slight decrease in wind, and return of
VFR conditions.
