Special Weather Statement issued April 26 at 3:14AM EDT by NWS Louisville KY
Clear skies and calm winds have allowed for areas of dense fog to develop in the Lake Cumberland region. River valley areas will see the most dense fog. If traveling this morning, use caution and turn on your low-beam headlights.
Special Weather Statement
Special Weather Statement issued April 26 at 3:35AM EDT by NWS Jackson KY
The combination of clear skies and light winds following the recent rainfall has led to widespread fog formation. The fog will likely be dense in valleys and areas where the rain was heavier on Saturday. This fog will dissipate by 10 AM. If traveling this morning, slow down, use low beam headlights, and allow plenty of time to reach your destination.

Pleasant Spring Warmth with Isolated Morning Sprinkles
A dominant high-pressure ridge will build across the Commonwealth, bringing unseasonably warm temperatures and mostly sunny skies. A weak, moisture-starved disturbance will cross central and eastern Kentucky during the morning hours, potentially producing isolated light sprinkles or virga before clearing out by the afternoon.
Confidence Assessment
Strong model agreement on the building high-pressure regime and thermal profiles ensures high confidence in the temperature forecast. The only minor uncertainty lies in the exact coverage of trace-level morning sprinkles.

Possible Outcomes
Weather forecasting involves uncertainty. Below are two scenarios representing the range of possible outcomes: the "Boom" scenario shows the worst-case/highest-impact result if conditions align unfavorably, while the "Bust" scenario shows the best-case/lowest-impact result if the forecast doesn't materialize as expected.
The 'Boom' Scenario
If the mid-level ridge builds more aggressively and cloud cover clears early, temperatures in the Purchase and Pennyrile regions could over-perform, reaching the mid-80s, while central Kentucky pushes toward 80°F.
The 'Bust' Scenario
If the morning shortwave tracks further south and manages to tap into slightly more moisture, a period of overcast skies and persistent light sprinkles could linger through midday, keeping temperatures in the 60s for the Bluegrass and Eastern Kentucky.
Model Disagreements
When models disagree, a call must be made to determine the most likely outcome. This decision is based on a combination of factors including model performance, historical data, and the models general accounting of each climatic region of Kentucky.
Boundary Layer Mixing Battle
GFS and NAM suggest deep mixing will allow wind gusts to reach 25-28 mph in the Bluegrass, while the GEM and Euro keep conditions much calmer with gusts below 15 mph.
Why GFS Wins
Given the high solar insolation and a dry adiabatic lapse rate through 800mb, momentum transfer from the low-level jet is highly probable during peak heating.
The Virga War
The NAM is aggressively forecasting high PoPs (80%) for light precipitation across central and southeastern Kentucky, whereas the GFS and Euro show a completely dry column. The discrepancy lies in how each model handles a weak mid-level vorticity lobe and the associated low-level dry air.
Why NAM Wins
The NAM historically handles shallow, clipper-like shortwaves and their associated cloud decks better within the 24-hour window. While accumulations will be negligible, the NAM's cloud and sprinkle timing is likely more accurate than the total 'phantom' dry solutions of the global models.
