Frigid Morning with Developing Afternoon Gusts

Kentucky will see a day of sharp transitions as high pressure departs the region. A frigid start with morning lows in the teens and twenties will give way to a breezy and cloudier afternoon. While cloud cover increases from the west, the state is expected to remain dry through midnight, with temperatures rebounding into the upper 30s and 40s.

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

High confidence in the cold start and gusty winds; lower confidence in the arrival time of clouds and the potential for outlier precipitation in the far Northeast.

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 Euro scenario verifies: moisture overcomes the dry boundary layer faster than expected, resulting in a light wintry mix in the Northeast valleys and light rain showers elsewhere by evening.

💨

The 'Bust' Scenario

Dry air maintains total dominance; clouds remain high and thin, allowing for more sunshine and potentially slightly higher afternoon temperatures but colder night lows.

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 Great Moisture Stand-off

The ECMWF (Euro) is a significant outlier, forecasting light precipitation across the state by afternoon and evening. The GFS, NAM, and GEM all maintain a dry forecast, pointing to significant dew point depressions and a moisture-starved boundary layer.

EURO
VS
GFS
VS
NAM
Why NAM Wins

The NAM's superior resolution of the dry boundary layer and its history of handling initial moisture return against a strong departing high makes its dry solution more credible for the first 24 hours.

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 robust nocturnal inversion exists between 950mb-900mb, which will erode by mid-day. 850mb temperatures will surge from -2C to +4C due to strong southerly warm air advection.

Thermal Boundary

The 0C isotherm at the surface will lift north across the Ohio River by 18z.

Diurnal Trend

The diurnal curve will be steep in the morning as the inversion breaks, then flatten in the evening as cloud cover and WAA counteract radiational cooling.

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. Weather is driven by the tightening pressure gradient between the departing high and an approaching lee-side trough.

Jet Stream Support

A 45-50kt low-level jet (LLJ) at 850mb provides momentum for gusty winds, while the upper-level jet remains north of the Great Lakes.

Energy Status

Weak vorticity lobes are pivoting through the cyclonic flow, but they are currently disconnected from deep moisture sources.

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 column is moisture-starved below 12,000 feet. Large dew point depressions (15-20F) create a significant virga risk but limit surface precipitation.

Precipitation Character

None expected at the surface; high-based stratiform clouds only.

Flooding Context

No hydrologic concerns as the forecast is dry.

Winter Physics

Accumulation & Layers

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

Layer Analysis

A warm nose (+4C to +6C at 850mb) is present, ensuring any outlier moisture would fall as rain for most, though Northeast KY valleys could see a fleeting snowflake at onset.

Crystal Habit

N/A due to dry column.

Road Impact

Dry roads expected; no accumulation.

Severe Risk

Instability & Shear

Atmospheric ingredients required for severe thunderstorms, including available fuel (CAPE) and storm organization (shear).

Shear Analysis

Strong low-level shear is present due to the LLJ, but no instability exists to support convection.

Instability Context

Surface-based and elevated instability are zero.

Primary Threat

None.
