Area Forecast Discussion
National Weather Service Indianapolis IN
438 PM EDT Wed Jun 8 2022

.Mesoscale Update...
Issued at 438 PM EDT Wed Jun 8 2022

Axis of highest low-level helicity continues to be centered along
and south of Indy Metro to the Ohio River in the 0-3km layer. This
is coupled with the surface moisture pooling north as dewpoints
begin to flirt with upper 60s to near 70. Surface winds have tried
to back, which would support the higher values of helicity in that
corridor. Satellite imagery also continues to indicate some vertical
growth to the cumulus field along with some collision to a few
cumulus bands further enhancing the vertical growth.

With this vertical growth, we are seeing the presence of ice aloft
which is allowing the charge to occur and produce lightning due to
the glaciation process aloft taking place.

Upstream the jet exit region is still somewhat displaced from
Central Indiana, but anticipate that as this continues to approach
the added lift could assist with some additional upscale growth to
the convective elements that are presently over Central Indiana. The
axis of greatest effective shear is still hovering along and south
of I-70, with values around 40-50kts. So still anticipate some
scattered updrafts to occur the next few hours, and the potential
exists that given the considerable shear and buoyant low-level that
an isolated tornado continues to be a concern.

Mesoscale Discussion from 150pm EDT...

Current observations and satellite imagery depict a surface low
over Central Illinois moving ENE with a warm front extending from
the low towards Vincennes, IN eastward to Seymour, IN to
Cincinnati. North of the warm front, winds remain SE while dew
points continue to rise into the 60s with a sharp gradient across
Central Indiana. 1720z IND ACARS sounding still has a very dry
layer aloft from the surface up to 4 km while low and mid level
lapse rates remain relatively weak. Leftover passing rain from the
dying MCS has helped saturate the column some across Central
Indiana. As this area of convection weakens and continues to push
into eastern Indiana, clearing and destabilization should being to
occur behind it. Still expecting the warm front to surge
northward over the next few hours advecting in a more moist and
unstable environment.

Along and south of the warm front currently is the area to watch for
potential severe storm development. Discrete supercells have already
began firing across South Central Indiana in an environment
characterized by around 2000 j/kg SB CAPE, 40-50 kt Bulk Shear, and
and 100-200 m2/s2 ESRH. Long, slightly curved hodographs in this
area indicate the potential for discrete, potentially splitting
supercells capable of producing large hail, damaging winds, and
isolated tornadoes. Current area to watch for severe storm
development is across Southern Indiana, however conditions for
severe weather should become favorable northward toward Central
Indiana as the warm front slowly pushes north.

&&

.Short Term...(This evening through Thursday night)
Issued at 301 PM EDT Wed Jun 8 2022

Main concerns for this evening:
-Potential for severe weather through 02Z
-Brief heavy downpours with convective elements
-Frontal passage will bring west/northwest flow overnight

Current Synoptic Setup: Satellite imagery showing several
interesting features across Central Indiana, starting with the mid-
lvl clouds sliding east and showing some anti-cyclonic turning with
some vertical growth in this area. Further south the cumulus field
has grown in its footprint, but equally beginning to show some
vertical growth as well with convergence of the cumulus layers. This
cumulus layer is also found in the area where surface dewpoints have
continued to rise with the moist surface conditions, as TD's near 70
degrees. Some backing in the surface winds are also noted between I-
70 and I-64 in Indiana. Further south across Northern KY the
atmosphere has been further destabilized, with surface flow more
backed to the south. ACARS data the last few hours across KIND have
continued to show a dry layer aloft; however, it has been steadily
moistening through the profile. That being said it is possible that
with some convective elements developing in this dry layer over
Central IN that some stronger updrafts could present larger hail
stones.

The jet exit region continues to be further upstream across IA, but
has been slowly pivoting southeast as the 850mb trough progress's
east. The deep layer shear has been rather robust overhead as well,
with values hovering in the 50-60kts range. This coupled with some
low-level helicity and boundaries proximity has introduced the
potential that upscale growth to convective elements could begin to
demonstrate rotating updrafts, thus we have tornado watch issued
until 2Z this evening. Latest surface obs also support this with an
axis of higher helicity centered along and south of IND to BMG.
Based on forward propagation, it would indicate the timing of
convection pushing east for Central IN would likely occur well
before this current ending.

Later Tonight through Thursday: 850mb trough axis continues to push
east overnight ushering in the frontal boundary. This will bring
much drier air into the lower levels and an end to precip as anti-
cyclonic flow brings diffluent flow through the lower-levels. Temps
should steadily fall into the mid 50s overnight, and with subsidence
eroding some of the low-level moisture expect a gradual clearing to
cloud cover overnight but not completely clear skies. Thur should
provide considerable sunshine with diffluent flow from ridging
overhead. Temps will rebound into the upper 70s with some fair-wx
cumulus progged or more diurnally driven.

&&

.Long Term...(Friday through Wednesday)
Issued at 301 PM EDT Wed Jun 8 2022

Friday-Friday night will feature rain chances returning yet again as
a seasonably strong H500 wave crosses the region during the day. A
relatively weak open-wave low will be the surface reflection...with
corresponding fronts aligned west-to-east across the Mid-West.
Forcing aloft should lead generally light to moderate rainfall...
with isolated thunder possible with the wave's timing matching
diurnal heating well. Potential for stronger thunderstorms appears
limited with near-zero instability despite adequate shear throughout
the profile.  Weak surface gradients will promote southwesterly
winds less than 10 mph, which is expected to provide only modest
dewpoints in the 50s...and slightly below normal temperatures
ranging from highs generally in the mid-70s to lows in the mid-50s.

Saturday-Sunday should be mainly dry as a couple more weak, quickly-
passing waves flow over the southern Great Lakes amid somewhat
strong upper-level northwest flow. Isolated showers will be possible
at times, generally across north-central and northeastern zones
which will be closer to the passing vort maxs.  Slightly lower
heights and partly sunny skies will combine to bring near normal
temperatures.

Monday-Wednesday will favor a slowly-advancing warm frontal zone
that will lead to the subtropical warm sector building into the CWA
underneath an amplifying mid-level ridge.  Rain will be most likely
Monday through early Tuesday...and although forcing aloft may be
marginal, precipitable water values quickly rebounding into the 1.50-
2.00 inch range should produce numerous showers along the boundary.
At a glance any thunderstorm potential should be guided by another
ample-shear, low-instability set-up, although these details will be
refined with future runs.  Appears the late Tuesday-Wednesday
timeframe will have deep southwesterly flow...around a strong trough
lifting from the central US into a larger south-central Canada
cyclone...that will promote noticeably warmer conditions.  Some
uncertainty surrounds the curvature of the broad central US upper
ridge into next week...as the troughs combining near the Great Lakes
may suppress heights over the Mid-West. Temperatures will likely be
above normal, although intensity of heat will depend on how much any
northern troughiness slides east or sags southward toward the
region. Appears greater likelihood for well above normal readings
across southern counties...with low chances for precipitation as the
pattern would not support adequate forcing along any approaching
weak boundaries.

The normal max/min for the Indianapolis Area through the long term
period is 81/62.

.Aviation...(18Z TAF Issuance)
Issued at 150 PM EDT Wed Jun 8 2022

IMPACTS:

* High confidence in TSRA with periods of MVFR conditions thru eve.
* Low confidence on specific timing and location of afternoon
  showers and storms.

DISCUSSION:

Current radar depiction across Central IN shows a few
showers/thunderstorms developing and lifting north along a frontal
boundary. This development has been tied to a greater instability
area, which is showing up in the satellite imagery this afternoon.
Surface winds continue to be weak from the southeast around 10-
14kts, but with some of the showers/thunderstorms these gusts will
be locally higher in and around the convective development.
Additionally given the airmass overhead, this will likely set the
stage that reduced VSBYs will occur in and around thunderstorms to
around MVFR possibly even IFR conds for a period of time.

Guidance is still indicating greater coverage to precipitation will
occur after 20Z through about 00Z to perhaps as late as 4Z in the
southeast airfields. Expect clouds to slowly rebound overnight with
flow turning west/northwest; however, if surface winds are light
enough this could present some pockets of fog developing around some
of the airfields. Otherwise expect VFR conds to return by daybreak
if not a bit earlier.
