A Bright Spring Day with Isolated Mountain Sprinkles
A robust high-pressure system will dominate the Commonwealth today, bringing dry conditions and abundant sunshine to most regions. The only exception lies in the far southeastern mountains, where a weak upper-level disturbance will trigger isolated light rain showers or sprinkles before clearing by evening.
Confidence Assessment
Confidence is high for the overall dry and mild forecast for 90% of the state. Points were deducted due to model disagreement regarding light precipitation in the far southeast and minor timing differences in morning cloud clearing for the Bluegrass.

Purchase Area
Expect a beautiful day with nearly 100% sunshine from start to finish. Temperatures will be the warmest in the state, reaching the low 70s by late afternoon.
Northwest Pennyrile
A perfect spring day with clear skies and a light breeze. Highs will reach the upper 60s, making it ideal for any outdoor activities.
Southwest Pennyrile
Full sunshine will prevail throughout the day with very comfortable temperatures. Morning lows in the 40s will quickly give way to afternoon highs near 70.
Barren River
A dry and bright day for the region with light winds and plenty of sun. Temperatures will peak in the upper 60s under a cloudless sky.
Louisville Metro
Morning clouds will quickly clear, leaving the city with a beautiful, sunny afternoon. Highs will reach the low 60s with a light northerly breeze.
Lincoln Trail
Expect clear skies and pleasant weather for Elizabethtown and Bardstown. A cool start in the morning will lead to a very comfortable afternoon in the mid-60s.
Lake Cumberland
A gorgeous day for the lake with light winds and afternoon highs in the low 60s. While some clouds may be visible to the east, your area will stay bright and dry.
Northern Kentucky
A chilly start to the day with temperatures in the 30s, but sunshine will prevail. Afternoon highs will stay in the mid-50s, making it one of the cooler spots in the state.
Inner Bluegrass
Expect a gray start to the day, but sunshine will break through by the afternoon hours. Temperatures will be cool but pleasant, topping out near 58 degrees.
Bluegrass Foothills
Clouds will be more persistent in the morning, but most of the day will be bright. It will be a bit on the cool side with highs in the upper 50s and a steady breeze.
Northeast Kentucky
Expect a mix of sun and clouds throughout the day. While most will stay dry, a stray sprinkle cannot be ruled out near the river.
Southeast Kentucky
The mountains will see the most cloud cover today with isolated light rain showers or sprinkles. Accumulations around 0.01 inches are possible, so keep the windshield wipers ready.
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 passing shortwave interacts with slightly deeper moisture, light rain showers could spread further north into the Bluegrass Foothills, though accumulations would remain under a tenth of an inch.
The 'Bust' Scenario
If the dry air entrainment from the building high pressure is more aggressive, the southeastern moisture will evaporate before reaching the ground (virga), resulting in a completely dry day for the entire state.
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.
The Southeast Moisture Scuffle
A disagreement exists between the global models (Euro/GEM), which forecast a completely dry day, and the mesoscale/regional models (NAM/GFS), which resolve enough shallow moisture for light rain in the mountains.
Why NAM Wins
The NAM typically handles shallow, low-level moisture trapped in the Appalachian terrain better than coarse global models. Its thermal profile shows a saturated layer below a sharp subsidence inversion that is often missed by the Euro.
