.SHORT TERM /THROUGH TONIGHT/...
Issued at 329 AM EDT Mon Sep 29 2025
Conditions are clear and calm this morning. A sprawling area of sfc
high pressure remains over the Ohio Valley and Great Lakes.
Persistent ridging aloft lingers over the Midwest and MS Valley.
This pattern, coupled with a dry column, will yield another
spectacular day.
Temperatures will continue to settle into the mid/upper 50s early
this morning, with warmer spots near 60 F. NE winds will increase to
10-15 mph this afternoon as mixing deepens to 6-7 kft. A few
afternoon cu will be possible, but mainly clear skies are likely
through the short term period. Temperatures appear likely to
overachieve slightly again today, so expect afternoon highs in the
mid/upper 80s. Tonight will be pleasant with mostly clear skies,
light winds, and lows in the mid 50s to around 60.

.LONG TERM /TUESDAY THROUGH SUNDAY/...
Issued at 329 AM EDT Mon Sep 29 2025
Mid and upper level ridging will still be anchored over the
Midwest and MS Valley on Tuesday. By this time, NHC expects Tropical
Storm Imelda to take a slightly faster turn to the northeast away
from the United States. The ridge aloft then slowly builds east
across the eastern CONUS during mid to late week. During this time,
strong sfc high pressure over Canada slides southeast over the
Northeast and Mid-Atlantic.
We still expect multiple days of fair weather here in central KY and
southern IN. Relatively low humidity will yield pleasant mornings
and warm afternoons. Highs in the low to mid 80s will be common,
with morning lows in the low to mid 50s.
The weekend also looks beautiful with high pressure lingering near
the East Coast. A cold front may push southeast through portions of
the Plains and Upper Midwest, but will not approach the forecast
area.

.AVIATION /18Z TAFS THROUGH 00Z WEDNESDAY/...

in a few spots.
