Area Forecast Discussion

157 AM EDT Mon Jul 24 2023

...Updated Aviation Discussion...

.Forecast Update...
Issued at 1029 PM EDT Sun Jul 23 2023

There are still some isolated showers and thunderstorms lingering
within central Indiana this evening along a weak remnant boundary.
These will continue to percolate as they move SSE along the boundary
through 04-06Z.

New development of showers and thunderstorms is still possible this
evening north of a modest jet streak. Any showers/thunderstorms that
due develop should stay under severe criteria with the only threats
being lightning and occasional high rain rates leading to localized
areal flooding.

Otherwise, no major changes needed to the ongoing forecast other
than fine tuning of POPs and associated sky cover forecast.

&&

.Short Term...(This evening through Monday)
Issued at 254 PM EDT Sun Jul 23 2023

Rest of Today.

As of early this afternoon, the MCV that helped bring a few showers
to the northern counties this morning was crossing into Illinois.
Convective temperatures have been met according to ACARs soundings
with 1200-1500 J/kg of SB CAPE, but a fairly dry column is limiting
the effective instability with only 200-300 J/kg when looking at ML
CAPE. The best forcing into the afternoon will be near and to the
south of the exiting MCV, so will focus POPs across the eastern
counties with lesser amounts further to the west.  The last few HRRR
runs have latched onto the exiting MCV and each successive run
continues to lower rain chances across central Indiana with a lack
of a good initiator for convection.

Tonight.

Generally conditions are expected for the overnight hours with the
potnetial for a few additional showers and storms along an
instability gradient across central Indiana.  The diurnally driven cu
field overhead will gradually dissipate after sunset as the PBL
begins to decouple.  With the lower expected coverage for storms
this afternoon, little convective overturning will create a slightly
more favorable environment for a few elevated showers and storms.
Initiation for these storms will be along the eastern periphery of a
slightly stronger 700-850mb jet which will peak in strength after
midnight.  Not expecting high coverage or anything more than a few
rumbles of thunder, but will be worth watching through the night.
Shallow ground fog looks to return again late tonight into tomorrow
morning with similar model signals to the last few morning with
mostly clear skies, calm winds, strong inversion, but marginal
moisture.

Monday.

The pattern will gradually begin to shift tomorrow with warmer
weather working its way into central Indiana. Dry weather is
expected for much if not all of central Indiana through the morning
hours, but more robust southerly flow will bring dewpoints into the
70s along with warmer temperatures along with renewed rain chances.
Model soundings show upwards of 2000 J/kg of instability during peak
heating, but a lack of initiation source will limit convective
development and coverage for storms. Models may also be overdoing
the afternoon heating with the ridge still well out to the west and
weak northwesterly flow aloft through the daytime hours.

&&

.Long Term...(Monday night through Sunday)
Issued at 254 PM EDT Sun Jul 23 2023

* Hottest weather of the summer thus far later this week.

* Frequent but low chances for thunderstorms through the week.

Continued expectations for this week are for a very large upper
level ridge centered over the Southwest/southern High Plains, with
upper level troughing of various intensities over the northeastern
US, with central Indiana stuck in between in an upper level
northwest flow regime much of the week.

Surface flow will be largely southerly or southwesterly much of the
period, with warm advection maintaining a hotter and more humid
airmass through the week, at least until potential passage of a cold
front very late in the period.

As a result of this northwest flow aloft and warm, moist southerly
flow at the surface, frequent chances for thunderstorms will be
required through much of the long term period, but any one period
will not have more than low chances, owing to significant
uncertainty with respect to convective evolution, as the resultant
forecast depends both upon subtle disturbances that longer range
models generally handle poorly, and evolution of prior convection,
which models also struggle with significantly.

By mid week, afternoon highs in the low to mid 90s will be
commonplace, with peak heat index values approaching or exceeding
100 degrees at times. This is unlikely to rise to the level of
headline necessity, but will be quite hot and sticky, particularly
given the relative lack of such heat thus far this season. It is
also worth noting that heat illness is possible even with similar or
lower heat index values, particularly with prolonged exposure or in
those who are particularly susceptible.

Folks across central Indiana should take care to limit heat exposure
this week and take frequent breaks when this is not possible.

.Aviation...(06Z TAF Issuance)
Issued at 156 AM EDT Mon Jul 24 2023

Impacts:
- TSRA at HUF at the immediate start of the period.
- VCSH at BMG from 07Z to 10Z.
- MVFR vsbys possible from 10Z to 13Z at LAF, HUF, BMG.
- More thunderstorms possible tomorrow evening at IND and BMG.
- Veering winds through the period.

Discussion:

Scattered showers/thunderstorms are currently located near HUF (as
of 06z) and will move southeast towards BMG through 10z. Enhanced
moisture in areas that see this activity could lead to the
development of localized patchy fog from 10z through 13z in
accordance with diminishing diurnal winds. This could lead to MVFR
vsbys at LAF, HUF, and BMG for a brief period.

More thunderstorms are possible beginning around 21Z tomorrow
afternoon and evening, primarily near KBMG and KIND. Limited
coverage warrants the use of Prob30 groups to capture these
thunderstorm chances at these two terminal sites in particular. As
the parent feature responsible for said chances approaches, expect
winds to veer and follow the diurnal strengthening curve through the
end of the period.
