===== Early Morning Shower Chances =====

Early this morning, regional radar mosaic shows a cluster of showers
and a few embedded storms moving across central Illinois and
Indiana, driven by a weak mid-level shortwave and differential
vorticity advection. Mesoanalysis also depicts a 850mb 35-40k LLJ
across the Ohio Valley, which has aided in WAA and moderate low-
level moisture advection. As a result, air temps are very mild
across the region, with KY Mesonet obs reporting 60s across the
entire area. These temps won`t budge much through the remaining
morning hours.

Isolated to scattered light rain will be possible through 13-14z
this morning as this shortwave passes overhead. However, not
everyone will see rain this morning, with the best precip chances
mainly along and north of the I-64 corridor, but also a lower chance
as far south as the WKY/BG Pkwys. Precip amounts should end up being
fairly light. ACARS data this morning continues to show rather dry
air below 700mb, which will evaporate most precip before reaching
the ground. Additionally, there could be a few rumbles of thunder
across southern IN this morning as model soundings indicate a meager
pocket of elevated instability. Fortunately, severe weather is
unlikely due to a strong low level cap to keep any storms elevated,
but we also just lack any substantial instability to support deep
convection.

===== Gusty Winds and Near Record Warmth Today =====

Drier weather and decreasing clouds are forecast for the area once
this early morning wave exits. The main impact for today will be the
gusty southwest winds, which will be in response to a tightening sfc
pressure gradient and mixing down winds from the LLJ today.
Southwesterly wind gusts of 25-35mph are expected across the entire
area, but could see some isolated 40mph gusts today. This pattern
will boost our WAA, leading to near record warm temps this afternoon
with highs reaching the low to mid 80s.

===== More Rain Chances Tonight and Friday =====

Gusty winds will continue this evening and tonight ahead of an
approaching cold front. This front will quickly drop into the region
from the north after 06z tonight, leading to a sharp wind direction
shift and increasing rain chances. We`ll see a decaying line of
showers and elevated storms follow just behind the actual front
Friday morning and push south through the entire area throughout the
morning. QPF has trended down slightly due to CAMs waning the
intensity of this line even more, with most locations expected to
pick up around 0.25" of rain with FROPA. Precip will taper off form
north to south through the afternoon, with drier conditions expected
by the late afternoon or early evening.

The frontal passage will bring a CAA punch to the area, and we`ll
see temps fall throughout the day. Max temps for Friday will likely
occur around or after midnight with temps in the 70s, but then fall
into the 50s by the afternoon.

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Issued at 315 AM EDT Thu Mar 26 2026

===== Drier Weather Returns for the Weekend=====

By Friday night, we`ll be deep within a strong CAA pattern and post-
frontal regime. Temps will fall from the upper 40s and low 50s to
the upper 20s and low 30s by Saturday morning, which will likely
lead to widespread frost. As mentioned in the previous discussion,
per guidance from our agricultural partners, the growing season has
begun, so we`ll likely need a frost/freeze headline for Saturday
morning.

Saturday will be quite a nice day as a strong sfc high sits directly
over us. Temps are forecast to rise into the 50s by the afternoon,
with plenty of blue sky and light winds. The sfc high will shift
east on Sunday, which will open us up to warmer return flow. In
response, temps are expected to be warmer with upper 60s, and dry
weather continuing.

===== Early-Mid Next Week =====

The upper flow is more zonal by next week, with jet energy focused
across the US/Canadian border. However, a mid-level ridge will be
sitting over the southeast US, which will provide low-level and mid-
level southwesterly flow through the Midwest and OH/TN Valley for
several days, leading to a persistent channel of moisture transport
from the Gulf. In this WAA pattern, we`ll also end up with temps
gradually warming through the week, with daily highs in the 70s
and/or low 80s, leading to daily afternoon destabilization. This
pattern will support daily shower and storm chances, mainly enhanced
by daytime heating, with lesser precip chances each night. Next week
is not expected to be a washout, with daily PoPs mainly limited to
30-40%.

.AVIATION /12Z TAFS THROUGH 18Z FRIDAY/...
Issued at 748 AM EDT Thu Mar 26 2026

Mid-level and high-level clouds are moving across the region this
morning, with some light rain chances through around 15z. Cloud
cover will decrease in coverage for the daylight hours, though the
primary impact to terminals today will be the gusty southwest winds,
which are expected to gust up to 25-30kts this afternoon. However,
VFR will continue throughout the period. Tonight, a cold front will
drop south into the region and bring a line of showers and storms.
Ahead of the storms, we will see a LLJ ramp up and bring LLWS to all
terminals. Timing for showers and storms will be after 9Z in
southern Indiana and after 12Z in central Kentucky.
