Area Forecast Discussion
National Weather Service Indianapolis IN
1254 PM EDT Tue Apr 4 2023

...Updated Aviation Discussion...

.Forecast Update...
Issued at 1002 AM EDT Tue Apr 4 2023

Elevated convection from warm advection had been producing some
small hail across mainly southern forecast area this morning. This
has moved east out of the area at this time, with some isolated to
scattered showers across the northeast half of the forecast area.

With warm advection continuing this morning, expect some isolated to
scattered showers will continue north into early afternoon. Will
keep some low PoPs there. Elsewhere, low clouds will persist this
morning most areas, with some breaks in the clouds across the far
southwest.

Some patchy fog will be around as well per latest surface
observations as low level moisture works into the area.

Questions remain on how fast the lower clouds will break up today
and the impact on temperatures from this. Given the extent of low
clouds, even upstream somewhat, have slowed down the partial
clearing and the rise in temperatures. However, since breaks have
already occurred, still expect them to expand and allow good warming
later today. Will have to keep a close eye on temperatures though.

&&

.Short Term...(Today through Wednesday)
Issued at 257 AM EDT Tue Apr 4 2023

There is a conditional risk of elevated thunderstorms developing
during the predawn hours this morning, driven by warm advection at
the nose of the low-level jet. The capping elevated mixed layer is
stout, however, and background midlevel height rises are
simultaneously occurring. Nevertheless, if a few convective cells
can initiate the MUCAPE profile is fairly thick and kinematics
marginally support storm tilt and organization. Hail, possibly
marginally severe, would be possible in the most intense cells. The
difference between convection and no convection is very subtle
details on moisture magnitude/depth at the level near the base of
the EML. SREF member soundings vary slightly with this, as do
outputs from various HREF members. With the deeper subsident regime
and no perturbations evident to counter this, there is a chance that
no convection forms. Any convection that does form should exit the
area by mid-late morning.

Blended model starting point (NBM) had a 7 degree error on
the high temperature for Indianapolis yesterday. This is due to
inertial lag from amplified trend in models, and PBL modeling
limitations. It is a known bias also on the windward side of ridge
with southwesterly flow aloft and trajectories back to warm deeply
mixed areas of the Southwest. Low to mid 80s for maximum
temperatures today seems reasonable in this pattern.

Strong capping EML and continued midlevel height rises with
amplifying synoptic-scale pattern will preclude thunderstorm
development today. In fact, the slower progression of the deep
evolving upstream trough means that we will probably be free of
convection through the first part of the night at least. The
window from roughly 06z Wednesday morning through 00z Wednesday
evening is complicated by the potential for multiple rounds of
convection and to the pre-frontal thermodynamic/kinematic
environment, and uncertainties with mesoscale forcing.
Furthermore, the track of the mid-latitude cyclone is such that
large scale forcing at this latitude is not particularly
noteworthy, using midlevel height trends as a proxy for large
scale ascent. Subtle height falls do occur during the period
mentioned above.

Here are a few possible scenarios for central Indiana:

1. Intense convection develops in the Ozarks region around or just
after the peak of the diurnal cycle today. It then grows up scale
with established cold pool and reaches our area during the predawn
hours Wednesday with attendant severe threat.

Around peak heating, stronger DCVA will still be over the High
Plains. But as the buckling subtropical jet phases with the polar
branch and the system deepens, strengthening moisture advection and
increasingly confluent low-level flow beneath steep midlevel lapse
rates should result in robust convection in the vicinity of the
Ozarks. The caveat to this scenario making it conditional is that
the upscale growth may be delayed if the deeper moisture surge lags.
This could delay cold pool establishment and MCS organization
considerably.

In this reasonable worst case scenario, any organized MCS would have
the potential for damaging winds and QLCS mesovortices/tornadoes
since nocturnal stabilization is expected to be minimal in strong
warm advection regime.

2. If the above scenario of organized convection reaching our area
does not occur during the predawn hours, continued deep moistening
and gradually more confluent low-level flow should encourage
convection to develop even before the diurnal cycle begins Wednesday
morning.

The extent/magnitude of this convection is unclear, but at least
modest instability and strong flow fields with sufficient shear for
storm organization would be present. There is a signal in some CAMs
that either of these first two scenarios could generally become
focused across the southern portion of our area, or along the Ohio
River through the first half of the day, with dynamic PV adjustments
on its poleward side at least temporarily limiting deep/robust
convection across central Indiana.

3. Although scenario #1 and #2 could ultimately impact the
frontal convection later in the day, it appears at least the
latter stage of what could be a robust/impactful convective event
to our west and northwest will reach our area late Wednesday.

Current thinking is the most intense convection would probably be
closer to the cyclone where midlevel lapse rates are steeper, in
perhaps one pre-frontal band and another frontal band. One or more
of these may tend to organized and reach our area late in the day
offering a second opportunity for convection and associated severe
hazards (primarily wind).

It is worth noting that although there is some uncertainty on timing
of potentially more than one round of convection, as well as
uncertainty with mode/organization, CAPE/shear parameter space is
more than favorable for all severe hazards including tornadoes. In a
reasonable worst case scenario, a localized strong tornado threat
may emerge somewhere in central Indiana, although there are
several scenarios where this would be unlikely. Details on the
mesoscale evolution will be communicated leading up to this event,
as uncertainties lessen.

&&

.Long Term...(Wednesday night through Monday)
Issued at 257 AM EDT Tue Apr 4 2023

The now higher latitude track of the mid-latitude cyclone discussed
in the short term section should preclude significant gradient winds
in its wake. The post-frontal environment is fairly temperate, with
temperatures no cooler than early April climatology on Thursday,
then moderating slightly to just above climo Friday as midlevel
heights rise. We enter a synoptically-inactive pattern with an
active northern branch shifting mostly into Canada and any troughing
relegated to the West this weekend. This should be a fairly warm
pattern for much of the country, including us. One shortwave passing
to our north on Monday will interact with meager moisture in
continental air mass without substantial moisture return. We have
only low probabilities for precipitation then. An early look at
medium range model data for the rest of the week indicates continued
broad area of positive 500-mb height anomalies, and perhaps even
warmer 2-m temperatures. There appears to be limited opportunity for
precipitation during this period.

&&

.Aviation...(18Z TAF Issuance)
Issued at 1254 PM EDT Tue Apr 4 2023

Impacts:

* MVFR/IFR improving south to north this afternoon

* Low level wind shear tonight, gusty surface winds tonight/Wed

* Some showers and storms at times late tonight through Wednesday

Discussion:

As warmer air allowing some mixing moves north this afternoon,
ceilings will gradually improve to VFR. A few showers can't be ruled
out as this occurs.

Winds will increase tonight into Wednesday both at the surface and
aloft. This will create low level wind shear conditions as well as
bring gusty winds at the surface. Gusts over 30kt are likely on
Wednesday.

Some convection is possible toward 12Z, but better chances for
convection will be from mid to late morning into the afternoon.
Unfortunately confidence in specifics remains low.
