Bitter Arctic Cold Grips Kentucky; Light Northern Flurries

A powerful Arctic high pressure system will dominate the Commonwealth on Thursday, bringing some of the coldest temperatures of the season. While most of the state will remain dry under a mix of sun and increasing mid-level clouds, a weak upper-level disturbance will likely trigger light snow flurries across Northern Kentucky during the afternoon. Temperatures will struggle to reach the freezing mark statewide, with morning wind chills dipping into the single digits and sub-zero range for northern counties.

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

High confidence exists regarding the temperature regime being well below seasonal norms. However, confidence is lower regarding the ability of very light moisture to reach the surface as snow flurries versus evaporating as virga.

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 moisture associated with the northern shortwave is deeper than modeled, light snow flurries could expand into the Bluegrass Core and Louisville Metro, resulting in a widespread dusting (up to 0.5") on all surfaces given the frigid ground temperatures.

💨

The 'Bust' Scenario

If the dry layer below 850mb remains as robust as the NAM suggests, all northern flurries will result in virga, leaving the entire state dry with only a persistence of overcast skies limiting any diurnal recovery.

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 Northern Flurry Feud

The Euro (ECMWF) identifies a weak surface trough and sufficient saturation to produce light snow flurries in Northern Kentucky, while the GFS and NAM remain stubbornly dry due to high dewpoint depressions in the lower atmosphere.

EURO
VS
GFS
VS
NAM
Why EURO Wins

The Euro typically handles weak synoptic forcing and marginal moisture in Arctic air masses with higher precision than the GFS 'smear' effect. Given the low-level lapse rates and DGZ placement, a flurry mention is meteorologically sound.

Affected Regions
NORTHERN KY

The Morning Low Margin

The GEM and GFS are significantly more aggressive with radiational cooling, bringing temperatures to near zero or sub-zero in Northern KY, while the NAM and Euro keep lows in the low teens.

GEM
VS
GFS
VS
NAM
Why GEM Wins

GEM's known cold bias often becomes an asset during established Arctic high-pressure regimes with clear skies and light winds, which maximize radiational cooling potential over snowpack or dry soils.

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 classic Arctic profile is in place with a strong surface-based inversion expected at daybreak. The entire vertical column from the surface through the tropopause remains well below freezing.

Thermal Boundary

The primary Arctic boundary is stalled well to the south over the Gulf Coast states, keeping Kentucky deeply entrenched in the cold sector.

Diurnal Trend

A non-standard diurnal curve is expected; while morning sun will attempt to warm the surface, increasing mid-level cloud cover by afternoon will halt recovery, keeping most areas 15-20 degrees below normal.

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 surface front will pass today; the Arctic air is already established. A weak secondary trough will cross the Ohio River between 18z and 22z.

Jet Stream Support

The state sits in the right-exit region of a 120kt polar jet streak over the Great Lakes, which generally promotes sinking air, though the southern fringe of the jet will provide enough shear for the light northern flurries.

Energy Status

A low-amplitude shortwave trough is the primary energy source, though its associated vorticity is weak.

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 largely dry (PWAT < 0.20"). Saturation is only noted in the 850-700mb layer, creating a high risk for virga.

Precipitation Character

Precipitation will be strictly stratiform flurries, very light in nature and high in snow-to-liquid ratio (approx 15:1).

Flooding Context

Zero hydrologic risk; ground is frozen or dry.

Winter Physics

Accumulation & Layers

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

Layer Analysis

No warm nose is present; 850mb temps are -12C. This is a pure snow/flurry profile with no risk of ice or rain.

Crystal Habit

Snow crystals will be small plates or thin dendrites given the cold temperatures within the moisture layer.

Road Impact

With pavement temperatures well below 30F, any flurries that do reach the surface will stick immediately, though accumulations will be negligible.
