Winter Snow Impacts Northern KY; Cold Rain Further South

A compact shortwave trough will transit the Ohio Valley on Tuesday, bringing a sharp divide in precipitation types across the Commonwealth. Northern Kentucky will experience accumulating snowfall, while central regions undergo a rain-to-snow transition. Southern Kentucky remains primarily in the warm sector, seeing cold, steady rain.

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

Confidence is high that a system will impact the state, but moderate on the exact southern extent of accumulating snow. The high-volatility nature of the rain-to-snow transition (-30) and slight timing disagreements (-10) result in a score of 60.

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 'Boom' Scenario: If the GFS-indicated moisture levels verify and the cold air undercuts the warm nose faster, Northern Kentucky could see a swath of 4-6 inches of snow, with the 1-inch line pushing as far south as the Western Kentucky Parkway.

💨

The 'Bust' Scenario

The 'Bust' Scenario: If the Euro's warmer boundary layer wins, the event remains a cold rain for almost everyone except the immediate Ohio River counties, resulting in only a dusting of snow on grassy surfaces and minimal travel impact.

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.

Western Kentucky Moisture Starvation

The NAM and GFS suggest a 'dry slot' will keep the Purchase and Northwest Pennyrile regions nearly dry, while the Euro suggests light showers will linger through the afternoon.

NAM
VS
GFS
VS
EURO
Why EURO Wins

The Euro handles moisture cutoffs with higher precision in these shortwave setups. We will include low-end PoPs (30-40%) to account for light rain potential.

Affected Regions
PURCHASENORTHWEST PENNYRILE

The NKY Snow Gradient

The GFS is an outlier with much higher snowfall totals (3-5") for Northern KY compared to the Euro/GEM (1-3"). The disagreement stems from the GFS producing more intense frontogenesis near the Ohio River.

GFS
VS
EURO
VS
NAM
Why BLEND Wins

While the GFS is often too aggressive with light-precip coverage, the NAM and GEM both support a healthy 2-3 inch solution. We will hedge toward the NAM/GEM consensus for accumulations.

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 low-level baroclinic zone is well-defined. North of I-64, the profile is entirely sub-freezing. South of the Bluegrass Parkway, a robust 4-degree Celsius warm nose persists at 850mb.

Thermal Boundary

The 32-degree surface isotherm will likely stall near the I-64 corridor before sagging into the Bluegrass Foothills late Tuesday night.

Diurnal Trend

Non-diurnal temperature curves are expected; many areas will see their high temperature in the late morning, with values falling through the afternoon as the front passes.

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 cold front will sweep NW to SE between 15Z and 22Z, marked by a sharp wind shift to the northwest and a drop in dew points.

Jet Stream Support

The Right Entrance Region of a 110kt 300mb jet streak provides broad synoptic lift over the northern half of Kentucky.

Energy Status

A compact 500mb shortwave trough with a vorticity max of 2.0e-4 is the primary driver of the precipitation shield.

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 fully saturated below 400mb in the east, while the west shows dewpoint depressions over 15F, suggesting a virga risk early in the day.

Precipitation Character

Mostly stratiform rain and snow. Frontogenetical forcing may lead to briefly heavier bands in Northern Kentucky.

Flooding Context

No flooding risk. Total liquid equivalents are generally under 0.40 inches, and the ground remains receptive.

Winter Physics

Accumulation & Layers

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

Layer Analysis

Northern KY shows a clean frozen profile; Central KY shows a melting layer that erodes late, while Southeast KY features a warm nose that may briefly support freezing rain at high elevations.

Crystal Habit

Standard 10:1 snow-to-liquid ratios are expected, with some higher ratios (12:1) possible in NKY as colder air deepens.

Road Impact

Accumulations will primarily occur on grassy and elevated surfaces initially, but pavement may become slick in Northern KY after sunset as temperatures fall into the 20s.
