Breezy and Unseasonably Mild with Scattered Showers
An unseasonably warm and breezy weather system will traverse the Commonwealth today, bringing scattered light rain showers and gusty morning winds. High temperatures will soar into the 60s statewide, with no risk of wintry precipitation. Wind gusts may reach 40-45 mph across western and central Kentucky before noon.
Confidence Assessment
High confidence exists for temperatures and the absence of wintry threats. The only minor uncertainty is the exact rainfall totals due to the virga risk highlighted by the GFS.

Purchase Area
Expect a very breezy day with wind gusts reaching 45 mph during the morning hours. While clouds will be thick, measurable rain is unlikely to reach the ground before evening.
Northwest Pennyrile
Gray skies will dominate the day with unseasonably warm temperatures in the mid-60s. Wind gusts of 40 mph are likely through noon, but rain chances remain very low.
Southwest Pennyrile
A very mild day with scattered light showers arriving by late afternoon. Rain totals will be minimal, likely only wetting the pavement.
Barren River
Expect gusty winds in the morning followed by periods of very light rain this evening. High temperatures will reach the low 60s.
Louisville Metro
Light rain showers will pass through the metro area during the morning hours. Winds will gust to 37 mph before lunch, making for a blustery day.
Lincoln Trail
Periods of light rain and drizzle are expected throughout the day. Accumulations around 0.1 inches are likely as the rain interacts with the escarpment.
Lake Cumberland
Steady light rain will increase in frequency through the afternoon. Expect unseasonably mild temperatures near 60 degrees.
Northern Kentucky
Light rain will arrive during the morning, tapering to drizzle by afternoon. Winds will be gusty at times, especially near the river.
Inner Bluegrass
Lexington will see periods of light rain throughout the day. It will be quite blustery with wind gusts reaching 39 mph.
Bluegrass Foothills
Cloudy skies and light rain showers will persist for much of the day. Winds will be gusty, especially over higher terrain.
Northeast Kentucky
While the morning may stay dry, steady light rain will move in by afternoon. Rainfall totals around 0.05 inches are expected.
Southeast Kentucky
The most consistent rain across the state will fall here this evening. Expect around a quarter-inch of rain with mild temperatures in the 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 low-level dry layer saturates faster than expected and the ECMWF's higher moisture transport verifies, rainfall totals could reach 0.50 inches in the southern and eastern regions, with wind gusts peaking over 50 mph.
The 'Bust' Scenario
The 'Bust' scenario involves dry sub-cloud air winning out, resulting in widespread virga where rain evaporates before reaching the ground, leaving most of the state with only trace sprinkles.
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.
Momentum Transfer Battle
The NAM suggests much higher surface wind gusts (45 mph+) compared to the ECMWF (25 mph) due to a more aggressive mixing of the 850mb jet core.
Why NAM Wins
The NAM typically resolves the mechanical mixing of a low-level jet in high-shear/low-CAPE environments more accurately than global models in the 0-24h window.
The QPF Divergence
The ECMWF is an aggressive outlier, forecasting up to a half-inch of rain in Southeast Kentucky, while the GFS, NAM, and GEM remain much drier, suggesting totals stay under 0.15 inches due to sub-cloud evaporation.
Why BLEND Wins
While the ECMWF is likely too wet, its depiction of orographic enhancement in the mountains is more realistic than the GFS 'smear.' We will lean toward the drier consensus for the west but incorporate ECMWF's higher totals for the Coalfields.
