Blustery with Passing Showers; Gusts Up to 45 MPH

A fast-moving cold front will sweep across Kentucky during the morning hours, bringing gusty winds and light, scattered showers primarily to the northern and eastern halves of the state. Following a brief afternoon lull, a southern stream impulse will return light rain chances to the southern tier during the evening. No wintry precipitation is expected as temperatures remain unseasonably mild.

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

High confidence in precipitation type and the arrival of gusty winds; however, model disagreement on the northern extent of evening moisture and the exact magnitude of wind gusts in the Bluegrass slightly lowers the score.

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 for this event involves the 850mb jet mixing more efficiently to the surface, resulting in widespread 50mph gusts in the Bluegrass. Additionally, if the southern moisture plume shifts 50 miles further north, the I-64 corridor could see measurable rainfall during the evening hours.

💨

The 'Bust' Scenario

The 'Bust' scenario assumes the dry air in the 700-500mb layer wins out, leading to widespread virga during the morning and evening, resulting in many areas remaining dry with nothing more than a few sprinkles.

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 Momentum Transfer Tussle

The NAM and GFS suggest a vigorous low-level jet mixing down 40-45 mph gusts, while the Euro remains much more conservative with wind speeds.

GFS

EURO
Why NAM Wins

The NAM handles the mechanical mixing and momentum transfer in the boundary layer significantly better than the global models during fast-moving frontal passages.

The Evening Moisture Cutoff

Disagreement exists on how far north the evening rain shield from the southern stream system will travel.

GEM
VS
ECMWF
VS
GFS
Why GEM Wins

The GEM provides a more realistic representation of the dry slot erosion, keeping the bulk of the evening precipitation focused along the TN/KY border.

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 well-mixed boundary layer will develop behind the morning front. Profiles are strictly above freezing throughout the lowest 3km, with 850mb temps ranging from 4C to 8C.

Thermal Boundary

A cold front will enter NW Kentucky around 08Z, crossing the I-65 corridor by 12Z and exiting the state to the east by 17Z.

Diurnal Trend

A non-diurnal trend will be present in the morning as cold air advection offsets solar gains, followed by a standard afternoon curve in the west where clearing occurs.

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

The front is marked by a sharp wind shift from SW to NW and a 10-15 degree dewpoint drop as it passes.

Jet Stream Support

Upper-level support is provided by the right-entrance region of a 110kt 300mb jet streak, primarily providing lift for the eastern half of the state.

Energy Status

A compact shortwave trough is pivoting through the Ohio Valley, providing peak vorticity between 06Z and 14Z.

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

Column saturation is limited to the 950-700mb layer; dry air aloft presents a virga risk, especially for Northern KY.

Precipitation Character

Precipitation will be light and stratiform. No convective elements or lightning are expected due to near-zero CAPE.

Flooding Context

No flooding concerns exist; total rainfall will remain under 0.15 inches for the vast majority of the state.

Winter Physics

Accumulation & Layers

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

Layer Analysis

No frozen layers are present; surface and 850mb temperatures are too warm for winter weather.

Crystal Habit

N/A

Road Impact

None. Roads will remain wet or dry throughout the period.
