.FORECAST UPDATE...
Issued at 928 PM EDT Fri Oct 3 2025
Most of the scattered convection from this afternoon and early
evening has diminished with just a few small showers lingering in
the Wabash Valley north of KHUF. Mid level cloud debris lingered as
well to the west of the Indy metro with mainly clear skies
elsewhere. 01Z temperatures ranged from the mid 60s to mid 70s.
The subtle weakness aloft downwind of the upper ridge over the
central U S remains in the Ohio Valley and may aid in isolated
showers continuing for the next few hours focused mainly in the
northern Wabash Valley with soundings showing weak instability still
lingering. The overall trend however for the remainder of the night
will be for showers dissipating and mostly clear skies taking over.
With light winds and increased moisture within the boundary layer...
will need to monitor for possible localized fog developing in the
predawn hours with locations that received rain earlier today being
most susceptible.
Lows will fall into the upper 50s and lower 60s over much of the
forecast area. Zone and grid updates out.

.SHORT TERM (This evening through Saturday)...
Issued at 217 PM EDT Fri Oct 3 2025
Rest of Today and Tonight.
As the cu field continues to grow across western Indiana coverage in
showers is likely to begin to increase with weak instability
interacting with a weak trough and vorticity aloft. Lift in the low
and mid levels is fairly minimal but enough to allow for some
vertical growth in the cu fields which has allowed for off and on
showers to persist through the day. Peak coverage is likely to be in
the 4PM to 8PM timeframe with decreasing coverage into the early
overnight with the loss of daytime heating. That being said, total
coverage will be fairly low with only 10-15 percent at most of the
areas expected to see any rain.
Skies will become mostly clear by 10 PM with some passing cirrus
aloft. Temperatures tonight will stay mild with the higher surface
dew points with most areas remaining in the low 60s.
Saturday.
The ridge aloft will gradually strengthen into early Saturday with
any lingering vorticity aloft from the weak trough dissipating by
Saturday morning. Skies are expected to be mostly clear outside of
passing cirrus and diurnally driven cu with no chance for rain.
Temperatures are expected to remain much above normal through
tomorrow with highs in the mid to upper 80s.

.LONG TERM (Saturday night through Friday)...
Issued at 217 PM EDT Fri Oct 3 2025
Saturday Night Through Tuesday.
The pattern will remain persistent through the remainder of the
weekend with ridging aloft and much above normal temperatures.
Forecast highs for Sunday are expected to be within a few degrees of
the record with another day of highs in the mid 80s likely. The
pattern will then begin to shift late Sunday into Monday as a
frontal system approaches from the northwest. Models are beginning
to hone in on a smaller window for the frontal passage which looks
to be Tuesday with scattered to numerous showers and a few rumbles
of thunder ahead of the front. Total QPF has been trending higher
over the last few model runs with the potential for localized
amounts as high as an inch.
Wednesday Through Friday.
Much cooler weather will move in behind the frontal passage with the
potential for lows in the upper 30s to low 40s Wednesday night and
highs in the upper 60s to low 70s through Friday. Surface high
pressure will dominate the weather pattern through the second half
of the week with dry weather expected.

.AVIATION (00Z TAF Issuance)...
Issued at 618 PM EDT Fri Oct 3 2025
Impacts:
- None
Discussion:
VFR conditions are expected to continue at the terminals through
Saturday evening. Slow moving isolated convection persists across
west central Indiana but should diminish shortly after sunset. Skies
will become mostly clear overnight into Saturday morning with light
southwesterly winds.
A subtle weakness aloft remains across the region on Saturday which
could generate a few showers once again for the afternoon although
confidence remains low in this occurring. Model soundings do suggest
diurnal cu development for the afternoon. S/SW winds at 5-10kts are
anticipated.
