Arctic Chill Grips Kentucky with Northern Snow Flurries

A potent Arctic air mass will remain entrenched across the Commonwealth on Monday. While the majority of the state stays dry under high pressure, a weak upper-level disturbance will clip Northern Kentucky and the Ohio River valley, bringing light snow showers and minor accumulations. Bitterly cold morning temperatures with sub-zero wind chills are expected for the Bluegrass and Northern regions.

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

High confidence exists for the Arctic temperature profile and the general location of the cold core. Confidence is lower regarding whether the light snow will overcome the dry lower atmosphere to produce measurable accumulation.

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 clipper-like shortwave digs further south and overcomes the dry sub-cloud layer, resulting in a widespread 0.5 to 1.0 inch of fluffy snow extending from Louisville through the Bluegrass Core.

💨

The 'Bust' Scenario

Dry Arctic air completely erodes the moisture associated with the shortwave, resulting in nothing more than scattered 'diamond dust' flurries in Northern Kentucky with zero accumulation.

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.

Arctic Valley Minimums

The GEM and NAM are significantly colder with morning lows in the eastern valleys and Bluegrass Core (3-5°F), while the Euro is more conservative (10-12°F).

NAM
VS
GEM
VS
EURO
Why NAM Wins

The NAM and GEM resolve shallow cold air damming and radiational cooling in Kentucky's complex terrain far better than the global Euro during Arctic outbreaks.

Affected Regions
LAKE CUMBERLANDBLUEGRASS CORESOUTHEAST COALFIELDSNORTHEAST KY

The Virga Wall

The NAM remains steadfastly dry for the entire state, suggesting the sub-cloud dry air will evaporate all hydrometeors. The GFS and GEM are more aggressive, showing a saturated DGZ and enough forcing to push light snow to the surface in the northern tier.

NAM
VS
GFS
VS
GEM
Why BLEND Wins

While the NAM correctly identifies the dry layer, the GFS/GEM synoptic support for the shortwave is high enough to warrant a mention of light accumulations in the North, though totals are capped due to the moisture deficit.

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

The atmosphere is characterized by a deep, sub-freezing isothermal layer from the surface to the tropopause. A strong surface-based inversion is expected during the morning hours, particularly in sheltered valleys.

Thermal Boundary

The freezing line (0°C at 850mb) is suppressed well south of the Kentucky-Tennessee border, leaving the entire state in the cold sector.

Diurnal Trend

A classic diurnal recovery is expected in the south, while the north will see a dampened curve due to persistent cloud cover and weak cold air advection behind the passing shortwave.

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

A weak secondary trough axis (arctic front) will move through the Ohio Valley between 10z and 18z, marked by a subtle wind shift to the northwest.

Jet Stream Support

The region sits in the right-entrance region of a 110kt upper-level jet, providing synoptic-scale subsidence for Southern Kentucky but allowing for some ascent in the northern tier.

Energy Status

A compact 500mb shortwave trough with vorticity values of 2.2e-4 s-1 is the primary driver for the northern snow potential.

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 significantly dry below 800mb. Dewpoint depressions of 15-20°F are common at the surface, creating a high risk for virga.

Precipitation Character

Precipitation will be light and stratiform, consisting of fine-grained snow or 'dry' flakes with high snow-to-liquid ratios (15:1).

Flooding Context

No hydrologic concerns; the ground is frozen and liquid equivalents are below 0.05 inches.

Winter Physics

Accumulation & Layers

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

Layer Analysis

No melting layers are present. The vertical temperature stack is entirely below freezing, ensuring 100% snow as the precipitation type.

Crystal Habit

Saturation within the Dendritic Growth Zone (-12°C to -18°C) favors small plates and dendrites, leading to high-quality, fluffy snow.

Road Impact

With pavement temperatures in the low 20s, any falling snow will immediately adhere to untreated surfaces, though the light volume will limit widespread travel impacts.
