.FORECAST UPDATE...
Issued at 952 PM EDT Fri Oct 23 2026

Similar conditions to previous nights continue across central
Indiana. Clear to mostly clear skies and light winds have allowed
temperatures to fall quickly this evening. Adjusted hourly
temperature forecasts based on these trends in observations.

Initial high clouds are dissipating some as they try to move
into the area, but some increase in high clouds is expected
overnight as they finally overcome the drier air.

Lowered low temperatures some in favored cold areas, but otherwise
no significant changes were made.

.DISCUSSION (This evening through Friday)...
Issued at 255 PM EDT Fri Oct 23 2026

Quiet weather is expected through the next seven days as surface
high pressure remains dominant across the region. Guidance is in
good agreement through the weekend, showing upper ridging moving
eastward across the region while surface high pressure centered over
the Northeast extends back into central Indiana. Large scale
subsidence from these features will continue to keep the forecast
dry. Light winds combined with mostly clear skies may continue to
promote patchy ground fog in climatologically favored locations the
next few nights.

Temperatures will slightly warm by Sunday due to return flow as
surface high pressure shifts further east. An upper trough moving
across Canada early next week will attempt to push a weak front into
the area. Latest guidance generally shows mean flow becoming parallel
to the boundary which should stall out front as it approaches.
Marginal forcing and very limited moisture from the gulf remaining
cutoff will likely limit any chance for measurable precipitation. A
slight cooldown of a degrees may be the only noticeable impact from
the system, but this will be more due to increasing clouds. Expect
dry conditions to persist as surface high pressure remains in
control.

Ensemble guidance begins to diverge towards late next week resulting
in greater uncertainty. Limited moisture return and weak overall
forcing should keep weather conditions mostly quiet. A deeper trough
along with more substantial moisture advection appears increasingly
likely towards the beginning of November which suggest greater
chances for precipitation. Exact details remain uncertain at this
time. Look for highs to generally range from the upper 60s to mid
70s through the period. Overnight temperatures will mostly fall into
the 40s with slightly warmer lows possible towards the middle of
next week

.AVIATION (00Z TAF Issuance)...
Issued at 657 PM EDT Fri Oct 23 2026

Impacts:

- Brief visibility reductions in patchy ground fog possible overnight
  through 13Z Saturday

Discussion:

Outside of some patchy ground fog overnight into Saturday morning,
VFR conditions are expected with surface high pressure in control.

Similar to recent history, some ground fog will likely develop at
all but KIND. Have put in MVFR visibility, but wouldn`t be surprised
to see brief IFR and worse, especially at KLAF.
