.FORECAST UPDATE...
Issued at 948 PM EDT Sat Sep 27 2025
No major changes needed to the ongoing forecast with conditions
generally evolving as expected. Temperatures have rapidly fallen
post-sunset with many sites already in the low to mid 60s. Fog
coverage tonight will likely be similar to last night with patchy
non-dense fog with areas near river valleys and other sheltered
locations where coverage is greatest. Dew points are running a few
degrees higher than this time yesterday which increases confidence
in overnight lows falling into the mid to upper 50s vs low to mid
50s which had been the case for the last few days.

.SHORT TERM (This evening through Sunday)...
Issued at 309 PM EDT Sat Sep 27 2025
Mid to upper-level ridging is building in from the west as troughing
over the Appalachians slides eastward. At the surface, high pressure
dominates and will continue to do so through the duration of the
forecast period.
In terms of weather, we can expect generally clear skies, light
winds, and above-average temperatures. Highs in the mid to upper 80s
are likely through the remainder of the weekend and into the coming
week. Lows dip into the 50s for the most part with ideal radiative
cooling conditions. Cooler temps in rural areas are anticipated with
low to mid 50s. Lows in the upper 50s to near 60 are more likely in
metro areas.
Patchy fog is possible during the overnight hours but duration and
coverage will be lower than previous nights. As moisture from recent
rainfall gradually dries up, fog should become more confined to near
rivers and in agricultural areas / farm fields.
&&
.LONG TERM (Sunday night through Saturday)...
Issued at 309 PM EDT Sat Sep 27 2025
The long term period will continue the streak of above normal
temperatures and persistent dry weather. Synoptically, troughing
will be set up across the west with low pressure from a tropical
system tracks along the Florida coast. Over central Indiana, stalled
high pressure will persist between the systems mentioned before. As
the week goes on, the tropical system will exit to the east while
ridging expands and stretches form the desert SW up to parts of New
England, continuing central Indiana under high pressure. High
pressure at the surface will only further the subsidence over the
area. Thus, the warm and dry pattern persists. High temperatures
will start off in the 80s and cool slightly by midweek to the upper
70s and low 80s with overnight lows in the 50s. At this time, there
is no to very little chance of precipitation through the long term.
Looking into the extended, ridging is expected to persist while CPC
is also indicating continued warmer and drier than normal
conditions.
While fire weather conditions are unlikely, especially following
moderate to heavy rainfall earlier this week, daily minimum relative
humidity values will drop to near 30 percent amid the unseasonable
warmth Monday, and again Thursday-Friday, albeit never with higher
gusts.

.AVIATION (06Z TAF Issuance)...
Issued at 1254 AM EDT Sun Sep 28 2025
Impacts:
- Patchy fog possible at HUF and LAF with MVFR to potentially IFR
vsbys
Discussion:
VFR conditions expected throughout the TAF period with the exception
of brief fog this mornign. Coverage of fog will be minimal, but
confidence is high enough for an MVFR mention at LAF and HUF. BMG
will also have to be watched for fog development. Any fog may
temporarily reduce conditions to MVFR with a lower chance for
brief IFR conditions. Winds will remain light and variable through
the period with mostly clear skies outside of some passing cirrus
and diurnally driven cu at around 050.
