Area Forecast Discussion
National Weather Service Indianapolis IN
722 PM EDT Thu May 19 2022

.Mesoscale Update...
Issued at 722 PM EDT Thu May 19 2022

Strong to severe thunderstorms continue to form along an east-west
boundary/quasi warm front extending from around St. Louis to
Lexington, KY. Warm, moist environment still exists north of the
front with dew points in the mid 60s and temperatures approaching 80
degrees. ACARS sounding data from IND abundant dry air aloft, steep
surface lapse rates and SB CAPE upwards of 1500 j/kg. Most of the
shear is located south of the front; however enough low level shear
exists north of it to support organized convection and isolated
supercells. Main threat north of the boundary in South Central
Indiana has been hail with reports of up to 2 inch hail around
Sandborn, Indiana.

As of the writing of this AFD, rain cooled air near the I-70
corridor southward to Columbus, IN has allowed for thunderstorms to
weaken in that area. Supercell still persisting across South Central
Indiana near Bedford with an unobstructed environment out ahead of
it and to its south.  Environment supporting the supercell is
characterized by 0-6km shear near 50 kt, CAPE around 2000 j/kg and
SHIP values around 1 to 2 according to the Louisville ACARS
sounding. Expect this supercell to persist as it trecks eastward
with large hail being the main threat as long as the storm remains
north of the stationary boundary.

...Next round of storms to the west...

MCV moving eastward from the St. Louis area and into Southern
Illinois along the stationary boundary may be the next focus for
thunderstorm development. The atmosphere behind the first complex of
storms in Indiana, but ahead of the MCV, has recovered nicely
according to observations. An environment consisting of dew points
in the 60s with temperatures rebounding into the 70s and lower 80s
should be conducive for continued thunderstorm development
associated with the MCV. However, as the evening progresses,
confidence decreases in how much recovery may happen across Central
Indiana before sunset. Highest confidence for more thunderstorm
activity later this evening is in Western and Southwestern Indiana
where the atmosphere is beginning to recover after the first wave of
storms. 0-6km bulk shear upwards of 40-50kt along and south of that
boundary with SB CAPE still over 2000 j/kg should be sufficient for
thunderstorm maintenance. Highest confidence in additional strong to
severe thunderstorm potential remains across SW portions of Indiana.

.Short Term...(This evening through Friday night)
Issued at 302 PM EDT Thu May 19 2022

Highlights...

* Severe weather possible this afternoon into tonight

* Damaging winds, large hail, and isolated tornadoes are possible

* Windy and hot on Friday

Severe weather is possible this afternoon into tonight as an MCV
approaches the area. Radar shows that convection has fired up over
Southwest Indiana and is moving NE. These storms will move into far
SW counties over the next hour. A warm front is currently draped
across Central Indiana with the southern half of the CWA in the warm
sector. Moisture advection within the warm sector has increased
dewpoints into the mid and upper 60s. High dewpoints along with
daytime heating have resulted in moderate to strong instability
across southern counties. An upper wave over Illinois along with the
approaching MCV will provide the main forcing for storms with the
warm front providing subtle forcing and enhanced directional shear.
Moderate to high instability, adequate low level wind shear, and
overall forcing may produce strong to severe thunderstorms this
afternoon into tonight. The primary threats are damaging winds and
large hail, but isolated tornadoes are possible. Storms are expected
to weaken overnight as instability decreases with the loss of
daytime heating. Southerly flow and low level moisture will limit
overnight cooling with lows in the upper 60s to near 70 degrees.

Friday and Friday night...

A strong LLJ will help advect warm moist air into the area. Partly
cloudy skies through the day will allow for sunshine and daytime
mixing. With this expected mixing, surface wind gusts could reach 40
mph at times. Model guidance is in good agreement that strong wind
gusts are possible tomorrow, especially over northwestern counties.
A cold front will slowly begin to approach Central Indiana late
Friday night with a low chance for showers and thunderstorms across
mainly NW counties. Confidence is low in any precipitation for
Friday night as guidance continues to trend slower with the
approaching cold front.

Temperatures will reach the middle to upper 80s. Indy's record high
for Friday is 90 degrees, last reached in 1977. Southerly flow and
low level moisture will keep overnight temperatures above average
with lows near 70 degrees.

&&

.Long Term...(Saturday through Thursday)
Issued at 302 PM EDT Thu May 19 2022

* Active weather expected this period.
* Rain chances Saturday afternoon and night
* More Rain chances on Tuesday afternoon through Thursday

Saturday and Saturday Night...

Models show SW flow in place aloft across Indiana ahead of a
broader...deeper trough in place over the northern plains. A surface
frontal boundary will be in place across NW Indiana allowing Central
Indiana to reside within the warm sector for the day. Forecast
soundings show favorable conditions for convection with attainable
convective temperatures and sufficient CAPE. Saturday should not be
a washout...but thunderstorm chances will be increasing as the day
progresses. By Saturday Night...models show the cold front sagging
southward across Central Indiana. Thus will trend toward high pops
on Saturday afternoon and evening as daytime heating initially
starts the storm chances...followed by additional development due to
the arrival and passage of the expected cold front.

Sunday Through Tuesday Morning...

Models show the cold front departing on Sunday morning as subsidence
and drying take place in the wake of the system. Aloft...weak mid
level ridging and strong surface high pressure are noted to be
pushing from the plains...across Indiana to the eastern Great Lakes
and Quebec by Tuesday Morning. Forecast soundings continue to
suggest a dry column through the period with mainly northerly or
northeasterly surface flow. Thus will trend toward a dry forecast
here with below normal high temperatures in the upper 60s and lower
70s.

Tuesday afternoon through Thursday...

Rain chances will return during this period. Models suggest a deep
upper trough pushing out of the Rockies...providing SW flow aloft
over Central Indiana on Tuesday afternoon. By Wednesday and
Thursday...this upper trough is expected to push to the southern
plains while continuing to eject weak upper forcing across the Ohio
Valley within the SW flow aloft. Meanwhile a surface frontal
boundary is depicted across Central Indiana and a weak surface low
is suggested to push across the front on Wednesday into Thursday.
Finally during this time...forecast soundings show a saturated
column...mainly on Wednesday and Thursday as the best forcing
passes. Pwats at that time are suggested to be near 1.80. Thus will
have highest pops on those days.

.Aviation...(18Z TAF Issuance)
Issued at 205 PM EDT Thu May 19 2022

IMPACTS:
-Thunderstorms this afternoon and evening, particularly at HUF and
BMG as well as IND
-S/SW winds gusting near 20 to 25 kts this evening and overnight.
Increasing some tomorrow morning

DISCUSSION: Largely clear skies to start out the TAF period.
Chances for storms then arrive this afternoon into evening as
storms have already formed over SW Indiana. Expecting these storms
to impact all sites except LAF from late this afternoon into
early overnight. South/ southwesterly winds will also begin to
pick up this afternoon with wind gusts to 25kts after 02Z. LLWS
will also be a concern late tonight to early tomorrow morning.
Wind gusts will increase some into tomorrow morning as well with a
jet overhead.
