Morning Showers Fade to a Bright and Mild Afternoon

A weak, moisture-starved cold front will transit the Commonwealth Sunday morning, bringing scattered light rain showers. Conditions will improve rapidly from west to east during the afternoon as high pressure builds in, leading to a pleasant and mild end to the day with temperatures in the upper 50s and low 60s.

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

High agreement on the liquid-only nature of the event and the timing of the frontal passage. The only uncertainty remains the exact rainfall totals in the eastern half of the state.

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

The GEM model verifies, bringing a more robust moisture plume into Southern and Eastern Kentucky, resulting in rainfall totals closer to 0.50 inches rather than light sprinkles.

💨

The 'Bust' Scenario

A faster frontal passage and more aggressive dry air entrainment result in almost no measurable rainfall for the I-65 corridor, with only a brief period of overcast skies.

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 Moisture Magnitude Conflict

The GEM is an aggressive outlier, predicting significantly higher rainfall totals (up to 0.75 inches) compared to the GFS, NAM, and Euro (all under 0.10 inches).

GEM
VS
GFS
VS
EURO
Why BLEND Wins

While the GEM is likely over-forecasting totals due to excessive moisture transport, the other models may be too dry in the upslope regions of the southeast. A blend favoring the drier solutions is used, but with slight increases in the Cumberland region.

Affected Regions
LAKE CUMBERLANDSOUTHEAST COALFIELDSBLUEGRASS FOOTHILLS

The Afternoon Warmth Battle

GFS and GEM are notably warmer with afternoon highs, suggesting widespread low 60s, while the NAM and Euro hold temperatures in the mid-to-upper 50s.

GFS
VS
GEM
VS
NAM
Why GFS Wins

Post-frontal cold air advection is weak with this system, and rapid afternoon clearing should allow for efficient solar heating, favoring the warmer GFS/GEM solution.

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

Standard moist-adiabatic profile ahead of the front with freezing levels above 8,500ft. Post-frontal profiles show significant drying above 850mb.

Thermal Boundary

The surface cold front enters the Purchase at 06Z and clears the Southeast Coalfields by 21Z.

Diurnal Trend

Standard diurnal curve in the west; the east will see a muted morning rise due to cloud cover followed by a late afternoon spike as skies clear.

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

Frontal passage is marked by a 45-degree wind shift to the west-northwest and a 10-degree drop in surface dewpoints.

Jet Stream Support

Moderate support from the right entrance region of a northern stream jet streak over the Great Lakes.

Energy Status

A weakening shortwave trough provides broad cyclonic flow but lacks intense localized vorticity.

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

Saturated only in the 1000-750mb layer; mid and upper levels are notably dry.

Precipitation Character

Primarily stratiform light rain and patchy drizzle.

Flooding Context

No flood risk exists as rainfall rates will remain below 0.10 inches per hour.
