.SHORT TERM /THROUGH FRIDAY/...
Issued at 309 PM EDT Thu Oct 2 2025
Temps have climbed into the low and mid 80s across the area under
mostly sunny skies. As was discussed before, seeing an area of
agitated cu across west central KY where a weakness in the upper
ridge is noted along with some positive area between the LFC and the
H6 inversion on soundings. ML CAPE values are reaching up round 500
J/KG but are also mitigated by pitiful mid level lapse rates. A few
blips on radar are showing up across western KY, and given high
DCAPE thanks to dry low levels, could get a few weak wind gusts out
of collapsing updrafts. As a result, will keep some 20% chances
across our far western CWA through the afternoon and early evening
to account for a stray shower or two associated with this agitated
cu field, modest instability axis, and potential for "chain
reaction" triggering.
Otherwise, look for a quiet overnight with perhaps a few very light
showers or sprinkles lifting northward toward our NW CWA by tomorrow
morning. Some patchy valley and river valley fog is possible along
with lows mostly in the 55 to 60 degree range.
Friday brings another warm/hot day with temps peaking mostly in the
mid 80s. A few upper 80s even possible, however some sky cover could
limit that a bit. Perhaps a few sprinkles or very light showers
across our NW in the AM, otherwise quiet and dry conditions continue
under the upper ridge.

The Weekend...
Upper ridging and surface high pressure will continue to dominate
our pattern through the weekend. This will keep us well above normal
for temperatures, with continued/worsening dry conditions to go
along with it. The upper ridge axis will steadily slide eastward
through this period, so we will be starting to see the end of the
dominant upper ridge by the end of the weekend. Saturday and Sunday
highs will mostly be in the low and mid 80s for highs (call it 82-
87). Meanwhile, look for comfortable lows in the 50s to around 60
each morning. Patchy river valley fog will probably continue to be a
common theme each night.
Monday - Thursday...
The upper ridge steadily breaks down in response to a digging
northern CONUS trough early week, and then completely loses the
battle by mid week. We`ll likely still hold onto mostly dry
conditions for early week (small shower/storm chances), but the best
chances will arrive mid week (Wednesday), when the trough axis sags
into the area along with a surface cold front trailing from an
eastern Canada low. Highest pops will continue to be Wednesday, with
gradually "cooling" temperatures early to mid week. Still looking at
highs in the low 80s on Monday, around 80 Tuesday, and then into the
70s by Wednesday.
Thursday looks to be dry once again in the post frontal regime as
surface high pressure builds in behind the departing cold front.
Could see some lows in the 40s by Thursday AM, with highs on
Thursday more seasonable in the low to mid 70s.

.AVIATION /18Z TAFS THROUGH 00Z SATURDAY/...
Issued at 208 PM EDT Thu Oct 2 2025
The forecast remains unchanged. VFR conditions are expected to
remain at all TAF sites through the forecast period. A few high
based cu, and a few high level clouds are expected to persist
through the period with light and variable winds. Any noticeable
wind directions will be SE overnight, and more likely SW through
early afternoon on Friday.
