.SHORT TERM (This evening through Tuesday)...

Rest of Today and Tonight.
Scattered showers associated with a broad area of mid-level
isentropic lift will continue to move northeast across much of
central and southern Indiana through the remainder of the afternoon
hours ahead of the arrival of a strengthening LLJ advecting Gulf
moisture into the southern portions of the state. This moisture
advection will continue to saturate the low and mid-levels with
plentiful lift being forecast after 00Z. There will be some
instability before the mid levels fully saturate and become moist
adiabatic which could bring a few rumbles of thunder, but expect
thunder coverage to be minimal with little to no risk for severe
weather as both instability and shear will be very marginal.
The surface front associated with the parent trough aloft will still
be moving into northern Illinois tonight with most of the forcing
that will be bringing the showers and storms associated more with
the southerly influx of moisture and broader lift. The heavier rain
is expected to begin after 00Z with an initial surge of moisture
from 00Z to 06Z followed by a banding area of precipitation towards
daybreak.
Tuesday.
The frontal passage is expected to occur during the day tomorrow,
but by then the better moisture advection will be southeast of the
forecast area, so other than isolated to scattered light rain
showers, don`t expect much additional precipitation during the day
on Tuesday as the thermal profiles will be moist adiabatic with only
weak frontal lift. There are some signals in cooler air working into
the mid-levels towards the afternoon which could bring some back-end
isolated to scattered showers and storms Tuesday evening as the
atmosphere becomes more unstable.
Total QPF for the event will be highly variable across the forecast
area with areas near Lafayette likely to only see amounts between
0.1 and 0.25 inches as the Gulf moisture remains to the south and
the forcing associated with the front is weak. Confidence in QPF
amounts in those locations is fairly high, while confidence in
amounts across southern Indiana is much lower as there is a lot of
variability as to where the heavier rain bands will set up. A broad
area of 1.25-2.00 inches is expected from roughly Vincennes to
Seymour, but amounts could be locally as high as 3 to 5 inches in
very isolated locations. These much higher amounts are more likely
to be along the Ohio River, but will need to closely monitor
precipitation tonight for any short-fused flood headlines as there
is a potential for a nearly stalled band of heavy rain towards
daybreak tomorrow.

.LONG TERM (Tuesday night through Monday)...
Issued at 139 PM EDT Mon Oct 6 2025
Tuesday Night Through Thursday.
There may be a few lingering light showers Tuesday night but most if
not all the precipitation should come to an end by midnight as the
front pushes southeast into the Appalachians. Cooler weather will
move in behind the front, but the strength of the cold air intrusion
is fairly weak with only a weak connection to the much colder
Canadian air. That being said, the intruding airmass will be much
drier with dew points in the mid to upper 30s which combined with
light winds and clear skies Wednesday and Thursday nights will
create marginally favorable conditions for frost in sheltered
locations across north central Indiana.
Confidence is fairly low with some uncertainty as to how cold
temperatures will drop, but for the most sensitive plants some
protection measures may need to be taken.Daytime highs Wednesday and
Thursday will be on the cooler than normal side as well with most
locations only reaching into the mid to upper 60s.
Friday Through Monday.
Surface and upper level flow will remain fairly stagnant late week
into the early weekend with light and variable surface winds keeping
the pattern persistent into Saturday with continued mostly clear
skies and slightly below normal temperatures. There is increasing
confidence in a clipper-esque system moving in from the northwest
Saturday into Sunday as a potential tropical low travels up the
Eastern Coast. Details are highly uncertain as these systems will be
close enough to interact with each other, but will have to watch out
for the potential for isolated light rain.
This system will also help keep temperatures mild with the warmer
than normal temperatures that were previously forecast looking more
unlikely at this time. Forecast details remain highly uncertain into
next week due to uncertainties in the evolution of the
aforementioned systems, but there is at least some agreement in
temperatures slowly trending warmer with precipitation chances below
normal.

.AVIATION (18Z TAF Issuance)...
Issued at 139 PM EDT Mon Oct 6 2025
Impacts:
- MVFR cigs dropping to IFR after 06Z
- Scattered showers with isolated thunderstorms through the evening,
  becoming widespread after 00Z
- Shower coverage becomes isolated again tomorrow, highest
  confidence at BMG
Discussion:
Cigs have already dropped to MVFR everywhere but LAF with isolated
to scattered showers currently impacting BMG. Coverage is expected
to increase through the day with rain and a few rumbles of thunder
expected at BMG through the night with less frequent coverage at HUF
and IND. LAF may see little to no rain until late tonight. Cigs will
continue to drop through the evening with IFR conditions after 06Z
and brief LIFR possible towards 12Z. Vsbys will predominately remain
MVFR to VFR outside of BMG where IFR vsbys will be common. Winds
will generally remains southerly at 7-12kts through the TAF period.
