Spring Warmth Returns with Gusty Afternoon Breezes
Kentucky will experience a significant warming trend this Sunday as high pressure shifts toward the Atlantic coast, initiating robust southerly flow. While the day will start crisp with morning frost in eastern valleys, temperatures will rebound into the 60s and lower 70s. A weak, moisture-starved disturbance will graze Northern Kentucky late in the evening, bringing increased cloud cover but minimal precipitation risks.
Confidence Assessment
High confidence exists for the warming trend and dry conditions for 90% of the state. Confidence is lower regarding the specific gust magnitude and whether the northern shortwave can produce measurable rain at the surface.

Purchase Area
Expect a beautiful day with plenty of sunshine and temperatures reaching the upper 60s to near 70. It will be breezy at times with southwesterly gusts around 25 mph.
Northwest Pennyrile
A sun-filled Sunday with highs reaching the mid-60s. South winds will be active through the afternoon.
Southwest Pennyrile
One of the warmest spots in the state today with highs nearing 70 degrees under clear skies.
Barren River
A very pleasant but windy day. Gusts may reach 35 mph, so outdoor decorations should be secured.
Louisville Metro
Sunshine for most of the day with highs in the mid-60s. A few clouds will arrive late this evening.
Lincoln Trail
Expect a bright day but hold onto your hats. Winds will be active with gusts over 30 mph at times.
Lake Cumberland
A cool start will give way to a beautiful afternoon with temperatures in the mid-60s.
Northern Kentucky
Most of the day will be dry and pleasant, but clouds will increase this evening with a 20% chance of a light sprinkle.
Inner Bluegrass
A crisp morning will be followed by a sunny, mild afternoon with highs in the lower 60s.
Bluegrass Foothills
Expect lots of sunshine and pleasant temperatures in the low 60s today.
Northeast Kentucky
After a frosty morning, temperatures will rebound nicely into the low 60s under sunny skies.
Southeast Kentucky
A peaceful day for the mountains with sunny skies and highs in the low 60s.
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 dry slot holds and mixing reaches the 800mb level earlier than expected, temperatures could overachieve by 3-5 degrees, pushing the entire western half of the state into the mid-70s with wind gusts exceeding 40 mph.
The 'Bust' Scenario
If mid-level cloud cover associated with the northern stream shortwave arrives earlier and remains opaque, high temperatures in Northern and Northeast Kentucky may struggle to exit the mid-50s.
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 Momentum Transfer Tug-of-War
Significant disagreement exists regarding surface wind gusts. The GFS suggests widespread 35-38 mph gusts, while the ECMWF remains much more conservative near 10-15 mph.
Why BLEND Wins
The pressure gradient is legitimately tightening, but the ECMWF often under-forecasts mixing in WAA regimes. GEM provides a reliable middle ground for gust potential near 30 mph.
The Northern KY Moisture Scuffle
The GFS is aggressive with a light rain signal (0.01-0.03") for the Cincinnati/Northern KY corridor late Sunday, while the ECMWF and GEM maintain a completely dry column.
Why EURO Wins
Sounding analysis shows a 'Fat' dry layer in the sub-cloud environment with surface dewpoint depressions exceeding 15F. This strongly favors the Euro/GEM dry solution, as any light precip will likely evaporate as virga.

Forecast Charts
These maps are generated by the weather agencies based on the raw data that the weather models predict. The final forecast is generated using the same raw data shown on the map. Keep in mind that the models (and therefore the maps) will generally disagree on specific parts of the forecast. Use these as guidance - not as a final prediction.
