.KEY MESSAGES...

- Persistent and breezy, especially in the afternoons, southwest
  winds will continue pushing warmer-than-average and seasonably
  moist air into eastern Kentucky through the rest of week.

- Expect several consecutive days with highs in the upper 70s to
  mid 80s, and mild overnight temperatures bottoming in the 50s
  and 60s.

- Look for daily small chances for showers and storms until a
  stronger cold front moves through the region later this weekend.

- Any showers and storms will provide some needed rainfall across
  portions of eastern Kentucky.

.UPDATE...
Issued at 557 PM EDT THU APR 2 2026

Isolated to widely scattered showers are lifting northward across
the forecast area early this evening. Instability remains minimal,
severely limiting convective organization and intensity. Activity
should dissipate by 8 to 9 PM with the loss of diurnal heating.

.SHORT TERM...(This evening through Friday night)
Issued at 257 PM EDT THU APR 2 2026

The latest surface analysis across the CONUS depicts a highly active
synoptic pattern. Currently, surface high pressure is centered over
Bermuda, with its influence reaching as far west as the Tennessee
Valley. Simultaneously, a 996 mb surface low is centered near the
junction of Nebraska, Kansas, Iowa, and Missouri. A warm front
extends eastward from this low through the Ohio Valley, lifting
northward toward the Great Lakes, while a cold front trails
southwestward into the southern Plains. Locally, eastern Kentucky
remains under the peripheral influence of the Bermuda High while
situated deep within the warm sector. This regime is characterized
by well above average temperatures and a robust south to
southwesterly wind field.

Through the remainder of the afternoon and overnight, the warm
sector air mass will continue to govern local conditions.
Temperatures are forecast to climb into the low to mid 80s. Strong
south to southwest winds will persist, bolstered by a strengthening
LLJ. Sustained winds of 10 to 15 mph with gusts of 25 to 30 mph are
expected through the early overnight hours. While a few isolated
showers or storms are possible this afternoon, they will lack
significant organization and should dissipate with waning diurnal
instability after sunset. Although the area is progged to remain
mostly dry overnight, upstream convective activity will track toward
the CWA by Friday morning. This increased cloud cover, from the
convective activity, will provide enough insulation to keep
overnight lows in the 60s while also inhibiting the development of
radiation fog.

Friday features a continuation of the warm sector regime ahead of
the approaching cold front. High-resolution CAMs suggest that
Thursday nights upstream convective activity may reach the western
CWA by Friday morning. This could bring isolated to scattered
thunderstorms to the region early in the day. Outflow boundaries
near the remnants of this morning activity may serve as the focus
for renewed development Friday afternoon. Assuming the air mass can
recover from morning clouds and rain, the thermodynamic environment
will support pulse-type thunderstorms capable of producing heavy
rainfall. Despite the convection, the area will remain warm with
highs in the low to mid 80s and persistent southerly flow. Any
lingering activity should diminish toward sunset, with widespread
cloud cover again maintaining mild overnight temperatures and
preventing valley fog.

The short term period is highlighted by the transition between the
retreating ridge and the encroaching warm sector. Temperatures will
remain well above average with gusty south to southwesterly winds.
While shower and thunderstorm chances exist both today and Friday,
activity is expected to remain disorganized, characterized primarily
by pulse-type storms with heavy rain and localized gusty outflow
winds.

.LONG TERM...(Saturday through Thursday)
Issued at 258 PM EDT THU APR 2 2026

The extended forecast period begins with the CWA firmly in the warm
sector as the primary surface low tracks northeast from the Mid-
Mississippi Valley into the Great Lakes. The associated cold front
will approach the area on Saturday. PoPs will increase from west to
east Saturday morning, with widespread showers and thunderstorms
expected throughout the day. Some storms may become strong Saturday
afternoon, particularly for areas along and north of the Mountain
Parkway where better forcing resides. Forecast soundings ahead of
the front indicate marginal severe weather indices, consistent with
the SPC Day 3 Marginal Risk across the northeastern CWA. The cold
front will progress through the region Saturday night, with FROPA
expected to be complete by Sunday morning.

Behind the front, surface high pressure will build into the region
and remain the dominant feature through the remainder of the period.
Temperatures will return to seasonal normals for the early part of
next week, followed by a gradual warming trend toward the middle of
the week. Overall, the extended period will be defined by the
Saturday cold frontal passage followed by a return to dry conditions
and seasonal temperatures under high pressure.

.AVIATION...(For the 00Z TAFS through 00Z Friday evening)
ISSUED AT 755 PM EDT THU APR 2 2026

VFR conditions are noted at all TAF sites with the 00Z issuance.
Any leftover diurnally-driven isolated showers are dissipating
leaving behind a mixture of mid and high clouds. Marginal LLWS is
expected across much of the area tonight as a low-level jet ramps
up. Toward 12Z/Friday, the remnants of a convective system to our
west will inch closer to the area with light precipitation
chances, primarily northwest of SJS-JKL-SME. Otherwise, southerly
winds around 10 kts or less tonight will shift southwesterly and
strengthen after 12Z, persisting through the rest of the period.

.JKL WATCHES/WARNINGS/ADVISORIES...
