Morning Rain Followed by Sharp Afternoon Temperature Drop

A cold front will sweep across Kentucky on Thursday morning, bringing rain to central and eastern regions before ushering in a much colder, drier air mass. Skies will clear from west to east by afternoon, but temperatures will fall through the day.

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

Confidence is high regarding the frontal timing and the temperature drop, but very low regarding precipitation type due to the ECMWF being a massive outlier with significant snow totals while others are dry.

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 follows the ECMWF outlier, where moisture lingers significantly longer as 850mb temperatures crash, resulting in a 2-4 inch snowfall and a hazardous evening commute due to a flash freeze.

💨

The 'Bust' Scenario

The 'Bust' scenario involves an even faster frontal passage where dry air scours out the moisture before sunrise, leaving the state with little more than a few morning sprinkles and a sunny but cold afternoon.

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.

Thermal Timing Battle

The NAM suggests a much sharper cold air surge (shallow CAA) compared to the more gradual cooling in the GEM/GFS.

NAM
VS
GEM
Why NAM Wins

The NAM typically handles the resolution of shallow, post-frontal cold air masses better in the 0-36 hour window.

Affected Regions
PURCHASENORTHWEST PENNYRILESOUTHWEST PENNYRILE

The Wrap-Around Moisture War

The ECMWF is a significant outlier, depicting a secondary wave of moisture that interacts with the incoming arctic air to produce several inches of snow. The GFS, NAM, and GEM all show a much drier solution with moisture exiting before the freeze.

ECMWF
VS
GFS
VS
NAM
Why GFS Wins

The GFS, NAM, and GEM show better consistency regarding the dry slot timing at 700mb. The ECMWF's projection of heavy snow is treated as an outlier due to its significant disagreement with mesoscale moisture profiles.

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 cold-frontal structure with a saturated warm-sector profile giving way to a sharp post-frontal inversion. 850mb temperatures crash from +4C to -8C behind the boundary.

Thermal Boundary

The surface freezing line moves from the Purchase region at 06z to the Bluegrass by 15z, clearing the state by 21z.

Diurnal Trend

Non-diurnal temperature curves will be dominant. High temperatures for the day will occur in the morning or early afternoon, with values falling steadily thereafter.

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

Cold front passage occurs between 03z and 12z from west to east, marked by a 90-degree wind shift and gusts to 30mph.

Jet Stream Support

The region is positioned in the right-entrance region of a 110kt 300mb jet, providing synoptic-scale lift.

Energy Status

A compact shortwave trough is providing moderate vorticity (1.4e-4 s-1) which peaks during the morning hours.

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

Pre-frontal saturation is deep (up to 500mb), but post-frontal dry air entrainment is rapid, leading to a quick cessation of precipitation.

Precipitation Character

Stratiform rain with embedded showers along the immediate frontal boundary.

Flooding Context

No flooding risk; liquid totals are expected to remain under 0.40 inches across the state.

Winter Physics

Accumulation & Layers

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

Layer Analysis

While the 850mb layer cools significantly, the moisture is expected to exit before the 'warm nose' is fully scoured out, limiting snow potential.

Crystal Habit

Minimal snow crystal growth expected as saturation is lost in the Dendritic Growth Zone as the cold air arrives.

Road Impact

Flash freeze risk is low but exists for elevated surfaces in the evening as residual moisture may freeze.
