Morning Showers Exit East; Clearing Skies and Breezy Today

A weakening cold front and associated shortwave trough will depart the Commonwealth this morning. Rain showers will persist across Central and Eastern Kentucky through the early afternoon hours, with the highest totals localized in the Southeast Coalfields. Rapid clearing is expected from west to east, with high pressure bringing a sunnier and stable afternoon statewide. Temperatures will remain seasonable, generally in the mid-to-upper 50s.

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

Extremely high agreement between all major models regarding the timing of the frontal passage, the absence of wintry precipitation, and the overall synoptic evolution. Minor uncertainty remains only in localized rainfall totals in the far east.

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 trough axis slows or a secondary vorticity lobe develops, rain and thick cloud cover could linger in the eastern valleys through sunset, keeping temperatures in the upper 40s.

💨

The 'Bust' Scenario

A faster-moving dry slot could scour out all clouds by mid-morning, leading to full afternoon sunshine and temperatures overperforming into the lower 60s for the I-65 corridor.

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 Orographic Squeeze

A significant disagreement exists regarding rainfall totals in the Southeast Coalfields. The GEM and ECMWF are aggressive with moisture transport, while the NAM is much drier, suggesting the terrain will disrupt the moisture plume too early.

NAM
VS
GEM
VS
ECMWF
Why GEM Wins

The GEM typically handles the enhancement of precipitation on windward slopes (orographic lift) more accurately than the coarser-resolution global models or the often-drier NAM in post-frontal setups.

Affected Regions
SOUTHEAST COALFIELDSNORTHEAST KY

The Low-Level Cloud Trap

Models differ on how quickly the post-frontal stratocumulus deck will break. The GFS is aggressive with a total clear-out, while the NAM suggests a subsidence inversion will trap moisture longer near the Ohio River.

GFS
VS
NAM
Why NAM Wins

The NAM soundings show a more realistic representation of the 850mb subsidence inversion, which frequently delays clearing in the Bluegrass and Northern Kentucky regions during spring cold frontal passages.

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

Vertical profiles indicate a standard post-frontal cooling stack with 850mb temperatures dropping to +2C to +4C. No significant warm noses or freezing layers are present, ensuring an all-liquid event.

Thermal Boundary

The cold front is currently tracking through Central Kentucky and will exit the Southeast Coalfields by 15z.

Diurnal Trend

A non-diurnal temperature trend will be observed in Eastern Kentucky, with highs occurring early in the day followed by falling or steady temperatures behind the front.

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 sharp wind shift from 220 degrees to 310 degrees and a notable drop in surface dewpoints from the mid-50s into the upper 30s.

Jet Stream Support

The region is favorably positioned in the right-entrance region of a 110kt jet streak, providing sufficient large-scale divergence to maintain the rain shield through midday.

Energy Status

A compact 500mb shortwave trough is providing the primary forcing for ascent across the eastern half of the state.

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

Deep-layer saturation is present east of I-65, but a dry slot is quickly moving into the western regions, as seen by widening dewpoint depressions in soundings.

Precipitation Character

Stratiform rain. Very low CAPE (<50 J/kg) precludes any convective or thunder threat.

Flooding Context

No flooding risk. Peak rainfall totals of 0.65 inches in the mountains are well below flash flood guidance, and the ground remains capable of absorbing this volume.
