Grey Skies and Seasonal Chill; Dry Conditions Prevail

High pressure will maintain dry but predominantly cloudy conditions across the Commonwealth. Chilly temperatures will persist, particularly in the northern and eastern valleys, while the southwest sees a slight warming trend.

Why is this happening?
Technical explanation of the atmospheric setup
Confidence Assessment

Confidence is high for a dry day statewide, but slightly lower regarding the exact extent of cloud cover and the potential for non-accumulating flurries in the Northeast on Day 6.

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

A slightly stronger mid-level ripple could produce scattered flurries across the northern half of the state, though dry surface air would still limit any accumulation to a trace.

💨

The 'Bust' Scenario

If the low-level moisture layer is thinner than modeled, the afternoon could see more substantial clearing, allowing temperatures in the southwest to reach 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 Northeast Flurry Feud

The GEM suggests a high probability of light precipitation in Northeast Kentucky driven by a weak shortwave, while the Euro remains almost entirely dry.

ECMWF
VS
GEM
Why UNCERTAIN Wins

While the GEM captures the shortwave energy, the significant dry air in the sub-cloud layer (1000-850mb) favors the drier Euro outcome for ground impacts.

Technical Analysis

This section provides a deep, physics-based explanation of the weather. Our AI system analyzed multiple atmospheric layers and variables from all available models to synthesize this technical overview.

Below you'll find detailed breakdowns of the atmospheric dynamics that are driving today's forecast, including thermodynamics, kinematics, and hydrology.

Thermodynamics

Stability & Temperatures

How temperature changes with altitude. This determines whether precipitation falls as rain, snow, sleet, or freezing rain based on the vertical temperature profile.

Thermal Profile Overview

A stable seasonal stack with a prominent subsidence inversion trapping moisture below 850mb.

Thermal Boundary

The surface freezing line will retreat north into Ohio by mid-morning, leaving all of Kentucky in a cool but above-freezing boundary layer.

Diurnal Trend

A muted diurnal curve due to high cloud fractions, with morning lows in the low 30s and afternoon highs in the 40s.

Kinematics

Wind & Energy

Wind patterns and atmospheric energy. Frontal passages, jet stream positioning, and vorticity tell us where and when lift will generate precipitation.

Frontal Passage

No frontal passage expected as high pressure remains the dominant surface feature.

Jet Stream Support

Kentucky sits in the right exit region of a 110kt jet streak over the Great Lakes, providing weak synoptic-scale lift.

Energy Status

A compact, moisture-starved shortwave trough is pivoting through the Ohio Valley.

Hydrology

Moisture & Precipitation

Moisture content and precipitation character. This reveals whether the atmosphere is saturated enough to produce precipitation, and what type to expect (steady vs. bursts).

Saturation Status

The boundary layer is nearly saturated, but the mid-levels are extremely dry, creating a high risk of virga.

Precipitation Character

Stratiform cloud cover with very light, non-accumulating flurries possible in the far northeast.

Flooding Context

No flooding risk; ground is stable and no measurable precipitation is forecast.

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.
