Area Forecast Discussion

308 PM EDT Tue Apr 29 2025

.KEY MESSAGES...

- Round of Severe Weather for South Central Indiana this evening
  with damaging winds the primary threat.

- Isolated to scattered showers and storms in far SW and southern
  Indiana tomorrow evening.

- Additional chances for isolated severe on Thursday as well.

&&

.SHORT TERM (This evening through Wednesday)...
Issued at 302 PM EDT Tue Apr 29 2025

Active weather continues through the next 24-30 hours with multiple
rounds of storms expected to impact Central Indiana, a few of which
could be strong to severe.

This evening and tonight…

Satellite and radar imagery as of 230 PM EDT show a cluster of
thunderstorms along the Mississippi river pushing east-northeast
into South Central Illinois. The environment ahead of these storms
and into Central Indiana remains conducive for these storms to
sustain themselves and remain strong to severe through the rest of
the afternoon and evening hours. The region remains entrenched
within the warm sector of a low pressure moving through the Great
Lakes with strong moisture advection northward, making for an
airmass more like July than late April with dew points approaching
70 degrees. Unidirectional 30-45kt southwesterly bulk shear
through the column and effective helicity of 100-200 m^2/s^2
within a humid, unstable environment will support lines of storms
and bowing segments with this next round. RAP Mesoanalysis shows
increasing DCAPE within this few hour dry slot as temperatures
make a run for 80 degrees, slightly increasing the low level dew
point depression… increasing damaging wind potential. Expect
storms to traverse eastward across Indiana from the 330pm-6pm
timeframe. The best threat for severe weather looks to be along
and south of a line from Sullivan County, IN to Bloomington to
Greensburg. Lower confidence exists on the northern extent of the
severe weather based on the trajectory of the complex in
Missouri.. But with the atmosphere recovering nicely within this
dry slot, the severe weather threat may extend further north
toward the I-70 corridor. Will be watching this closely this
evening. For now, South Central Indiana has the greatest threat of
severe weather with damaging wind gusts and isolated tornadoes.

Cold front pushes from north to south through Central Indiana within
the 9 PM to 2 AM timeframe, switching winds around to the north and
advecting a drier airmass into the state. This front is likely to
stall out along or south of the Ohio River overnight. Light winds
behind the front and nearly saturated boundary layer may lead to
areas of fog overnight along and north of the frontal boundary.
Confidence is low as dry air advection may keep dew point depressions
large enough to inhibit fog development; however wind sheltered areas
and valleys would have the best chance for any fog. Cold air advection
behind the front will lead to lows rangings from the mid 40s to
mid 50s across Central Indiana.

.Wednesday…

The aforementioned cold front from the previous day hangs around
the Ohio Valley much of the day Wednesday, slowly pushing north into
Central Indiana as a warm front by the evening. With the front south
of Central Indiana for at least the first half of the day, expect
fairly benign conditions to begin the day. Mid to high level clouds
will be streaming in from the southwest over the front; but overall
a drier and cooler airmass with highs in the mid 60s to mid 70s are
in the forecast for Wednesday.

Focus shifts to Wednesday evening as the front pushes northward into
South Central Indiana. While the best forcing for ascent will be further
west along the cold front, there may be enough lift over the front
and moisture advection northward for an environment supportive of
scattered convection along and south of the boundary. There are a
few aspects of tomorrow evening’s set working for severe weather and
few working against, which should keep the overall coverage of storms
down. Parameters working for severe weather will be backed surface
winds along and south of the front, increasing instability values,
0-6 km bulk shear 35-45 kts, lift over the front, and elongated
hodographs indicating an environment conducive for a few discrete
supercells. Factors working against severe weather and lowering
confidence tomorrow evening are the potential for weak mid level
lapse rates, speed at which the warm front moves potentially keeping
greatest instability south, and weaker low level shear. While the
threat is marginal, the areas to watch tomorrow are along a line
and south of Sullivan to Bedford to Seymour. Most locations north
of this line, including the I-70 corridor, Indy Metro and points
north may be mainly dry Wednesday, with the best chance for any
storms into the overnight hours and Thursday morning.

There likely will be a strong south-north humidity and temperature
gradient across the state with warmest areas in the 70s in Southern
Indiana where the storm threat is. Mid 60s to low 70s likely north
of the boundary.

&&

.LONG TERM (Wednesday night through Tuesday)...
Issued at 302 PM EDT Tue Apr 29 2025

The first part of the long term period will continue to see chances
for showers and thunderstorms, with some storms potentially being
severe, as a boundary with SW flow lingers over the region. This
weekend and beyond will then see sunny and quiet conditions as upper
ridging and high pressure settle in.

A short wave will start to move through Wednesday night with an
additional surge of showers and storms passing through central Indiana.
Cant rule out a few of these storms to still be potentially
severe, lingering from the afternoon storms. The arrival of stronger
850mb flow Wednesday night will increase convective coverage and enable
deeper low level moisture to return into central Indiana. Strengthening
low pressure will track from the Missouri Valley into the Great Lakes
Thursday with a noted increase in 850mb flow late day immediately
ahead of the approaching cold front. The larger surface low will continue
to slow push eastward through the day Thursday which will again see
the potential for a few storms again being severe as storms pass
through. Again, chances for showers will continue into Friday as an
additional short wave passes through the larger stalled trough,
but at this time not expecting severe with this wave.

Going into the tail end of the week and weekend, upper ridging will
progress, finally pushing the stalled system off to the east. This
replace the stormy pattern for a quiet and sunny system. Expect the
remainder of the long term period to fluctuate around normal
temperatures.

.AVIATION (18Z TAF Issuance)...
Issued at 118 PM EDT Tue Apr 29 2025

Impacts:

- Mainly VFR outside of storms this TAF period.

- Thunderstorms possible late this afternoon into early this
  evening, mainly at BMG.

Discussion:

Satellite and radar imagery shows morning storms pushing eastward
into Ohio with VFR conditions in the wake of that convection.
Looking upstream, there is a complex of storms in SW Missouri on
track to push into southwest and south central Indiana within the
next 3-6 hours. Best threat for storms is at KBMG with KHUF and
KIND being on the far northern edge of the risk. Damaging winds in
excess of 60 mph, erratic wind directions in storms, brief
periods of IFR cigs and vis, and lightning are the main threats
later this afternoon.

Outside of storms, IND ACARs sounding still shows deep low level
mixing above 1 km agl, working to bring down higher winds from
the low level jet. Expect SSW winds at or above 12 kts through
the day, diminishing after sunset. A cold front pushes in from
north to south within the 02-06z timeframe, switching winds around
to the north for the overnight hours. Winds switch back to
southerly tomorrow late morning as the boundary shifts back north.

Cold front pushing through will usher in drier air, which should
allow for VFR cigs at KIND, KHUF, and KLAF. Lower confidence in
VFR cigs at KBMG as the front may become quasi-stationary in
south central Indiana overnight. Along and north of that boundary,
there is a slight chance for fog towards sunrise; however
confidence on that remains low at the moment.
