Dry and Chilly with a Breezy Afternoon Transition

High pressure will shift eastward today, transitioning Kentucky from a frigid start to a sunny, breezy afternoon with temperatures recovering into the 40s.

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

High agreement among GFS, NAM, and GEM on a dry airmass and high-pressure dominance; however, the score is penalized due to the extreme synoptic disagreement presented by an anomalous and erroneous ECMWF solution.

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 weak northern-stream clipper tracks slightly further south, introducing scattered mid-level cloudiness and a few non-accumulating flurries along the Ohio River.

💨

The 'Bust' Scenario

Stronger-than-forecast warm air advection and full solar insolation allow temperatures to over-perform, pushing highs into the low 50s across Western Kentucky.

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 Ghost Blizzard of the East

A massive divergence in precipitation existence occurs as the ECMWF depicts a historic 36-48 inch snow event for Central and Eastern Kentucky, while the NAM, GFS, and GEM show a completely dry forecast.

ECMWF
VS
GFS
VS
NAM
Why NONE Wins

The ECMWF output shows physically impossible liquid-equivalent values exceeding 1000 inches in some grids, indicating a severe convective feedback error. Synoptic continuity and dry-air entrainment in all other models confirm a high-pressure regime is the only viable outcome.

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 temperature stack shows a classic post-high-pressure structure with a decaying overnight radiation inversion. Mid-day profiles are nearly adiabatic up to 850mb.

Thermal Boundary

The 32F surface isotherm retreats north of the Ohio River by 15Z-17Z across most of the state.

Diurnal Trend

Standard diurnal curve with rapid warming after 14Z following a cold start in the low 20s.

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; Kentucky remains in a return-flow regime as surface high pressure shifts to the Carolinas.

Jet Stream Support

Upper-level support is minimal under broad ridging, though a 35kt low-level jet at 850mb promotes breezy surface conditions.

Energy Status

Vorticity levels are at minima as broad cyclonic flow remains well to the north.

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 atmospheric column is deeply undersaturated with PWAT values below 0.20 inches, precluding any precipitation.

Precipitation Character

No precipitation; column suppression is dominant statewide.

Flooding Context

Stable hydrologic conditions with zero risk of precipitation-induced flooding.

Winter Physics

Accumulation & Layers

Specific physical factors affecting winter weather, including the vertical melt/freeze profile and snow quality.

Layer Analysis

The column remains mostly below freezing in the morning, but the total lack of moisture prevents any winter weather.

Crystal Habit

Not applicable due to dry conditions.

Road Impact

Roads will remain dry throughout the period.
