.DISCUSSION (This evening through Sunday)...
Issued at 232 PM EDT Sun Oct 25 2026

Rest of This Afternoon through Tuesday...

High clouds and some mid clouds will continue to spill across an
upper ridge through Tuesday, bringing partly cloudy conditions at
times.

The ridge itself will get pushed south a bit by upper waves well to
the north of the local area. This will allow a surface cold front to
sag south into central Indiana later Monday into Monday night. This
front will get pulled back north as a low pressure system moves into
Minnesota on Tuesday. With minimal moisture and little or no
forcing, no rain is expected with the front.

The cooler air behind the front most likely won`t reach into central
Indiana. Thus, expect highs in the 70s to continue with lows in the
40s. Patchy ground fog will develop near sunrise Monday and Tuesday
with light winds continuing. The fog may be muted by thicker cloud
cover though.

Wednesday through Friday...

A weakening upper wave will move northeast into the lower Great
Lakes Wednesday. This may bring additional clouds but again forcing
and moisture across central Indiana will be low enough to continue a
dry forecast.

A surface cold front will try and work south Thursday and Friday.
Guidance differs on how far south this front gets by late Friday.
With upper flow generally west to southwest ahead of another upper
wave, feel that the front will likely remain north of the area. Will
continue a dry forecast and go with the warmer guidance.

This means that highs will continue to be in the 70s, with perhaps
some upper 70s for parts of the area.

Halloween Weekend...

Any lingering upper ridging will exit as multiple upper troughs move
through next weekend. Uncertainty remains high on the details, but
for now it appears that the best forcing and moisture will arrive
overnight Saturday night into Sunday morning, with only low chances
for rain during Halloween evening events.

If the front remains north, highs will be in the 70s. However, a
more southern front as well as any rain would keep readings lower,
especially on Sunday.

.AVIATION (18Z TAF Issuance)...
Issued at 1254 PM EDT Sun Oct 25 2026

Impacts:

- Ground fog possible near 12Z Monday, MVFR and worse possible

Discussion:

Outside of any ground fog early Monday, VFR conditions are expected
through the period.

High clouds will move through at times through the period, with some
mid cloud around on Monday as well. Similar conditions to previous
nights will lead to patchy ground fog developing again. Thicker high
clouds might lower the odds, but for now will still put in a TEMPO
for MVFR at KLAF/KHUF around 12Z Monday. Cannot rule it out at KBMG
as well.

Winds will remain light. A shift to a more northerly direction will
occur at KLAF later Monday and at KIND Monday evening.
