Dry Arctic Front Brings Gusty Winds and Sharp Cold Snap

A strong, moisture-starved cold front will sweep across Kentucky on Saturday, ushering in a much colder air mass. While the day will be precipitation-free for the vast majority of the state, gusty northwest winds will make temperatures feel significantly colder than the actual reading.

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

High confidence in the temperature crash and wind gusts; however, the lone Euro solution showing snow in the West introduces a slight penalty for model disagreement on precipitation existence.

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-rich ana-front solution from the Euro verifies, a narrow 3-hour window of light snow could produce a quick coating to 1 inch of accumulation in Western Kentucky (Purchase/Pennyrile) before the dry air scours it out.

💨

The 'Bust' Scenario

A faster-than-anticipated clearing of the mid-level cloud deck allows for more solar insolation, keeping afternoon highs 2-3 degrees warmer, though the wind chill impact remains unchanged.

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 Cold Air Damming Discrepancy

The NAM and GEM maintain colder surface temperatures in the Eastern Kentucky valleys, while the GFS warms the region more aggressively prior to frontal passage.

NAM
VS
GEM
VS
GFS
Why NAM Wins

The NAM historically resolves shallow cold air and valley inversions better than global models. Cold air damming (CAD) is likely to persist until the pressure gradient forces mixing.

Affected Regions
NORTHEAST KYSOUTHEAST COALFIELDS

The Moisture Mirage

The ECMWF (Euro) attempts to develop a moist ana-frontal structure with 0.10-0.20 inches of liquid equivalent, resulting in a snow threat for Western KY. The GFS, NAM, and GEM all show a critically dry column with dewpoint depressions exceeding 15°F.

EURO
VS
GFS
VS
NAM
Why BLEND Wins

Siding with the GFS/NAM/GEM consensus on dry air. Soundings show a significant dry slot above 850mb that the Euro likely over-saturates. The dry solution is more physically consistent with the 250mb jet exit region subsidence.

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 post-frontal cold air mass is established. The vertical profile shows a sharp inversion in the morning across Central and Eastern KY, which will break by midday as mixing increases behind the front.

Thermal Boundary

The surface freezing line moves from the Purchase at 06Z to the I-75 corridor by 18Z.

Diurnal Trend

Non-diurnal trends are expected. Temperatures will peak in the late morning or early afternoon before plummeting as the 850mb -10C to -12C isotherm enters the state.

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

Sharp front marked by a 180-degree wind shift to the NW and surface pressure rises exceeding 4mb/3hr.

Jet Stream Support

Right-entrance region of a 130kt jet promotes subsidence, which is the primary reason for the dry forecast despite strong vorticity.

Energy Status

A compact shortwave trough provides moderate cyclonic vorticity, but it is moving through a moisture-starved environment.

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. Large dewpoint depressions in the mid-levels will result in any precipitation aloft evaporating as virga before reaching the ground.

Precipitation Character

Mostly non-precipitating, though a few non-measurable flurries are possible in the far North and East.

Flooding Context

Zero risk. PWAT values are near the 10th percentile for January.

Winter Physics

Accumulation & Layers

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

Layer Analysis

The entire column is below freezing behind the front, but the lack of moisture in the Dendritic Growth Zone prevents snow accumulation.

Crystal Habit

Not applicable due to lack of saturation.

Road Impact

Roads will remain dry. Strong winds and low dewpoints will quickly sublimate any residual moisture on road surfaces.
