Strong Cold Front Brings Rain East and Sharp Temp Drop

A powerful cold front will sweep across Kentucky on Wednesday. Western Kentucky will remain mostly dry with falling temperatures, while central and eastern regions will see light to moderate rain showers. Non-diurnal temperature trends will be common, with highs occurring early followed by a sharp afternoon chill and gusty winds.

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

High confidence in frontal timing and a sharp temperature drop. Moderate confidence in precipitation totals due to the significant dry air present in the GFS and NAM soundings for Western Kentucky.

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 front slows and moisture transport from the Gulf overachieves, the Eastern Coalfields and Bluegrass could see rainfall totals exceeding 0.50", with rain lingering longer into the evening hours.

💨

The 'Bust' Scenario

If the GFS solution verifies, the dry-slotting will be total. This would result in a windy, cloudy day statewide with virtually no measurable precipitation reaching the ground.

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 Moisture Disconnect

A significant disagreement exists regarding whether the intense synoptic lift can overcome low-level dry air. The GFS predicts a completely dry day, while the NAM and Euro suggest enough saturation for measurable rain in the east.

NAM
VS
GFS
VS
EURO
Why NAM Wins

NAM's superior resolution of mesoscale boundaries and low-level moisture profiles suggests that the synoptic lift from the 160mph jet will successfully saturate the column in the eastern half of the state, despite the GFS 'smear' of dryness.

Affected Regions
BLUEGRASS CORENORTHEAST KYSOUTHEAST COALFIELDSLAKE CUMBERLAND

Frontal Wind Magnitude

The Euro is notably weaker with surface wind gusts compared to the NAM and GFS, which show robust momentum transfer from the jet aloft.

NAM
VS
GFS
VS
EURO
Why NONE Wins

The intense 150kt+ jet core supports the higher wind values seen in the NAM and GFS. We are leaning toward a consensus of these two models, ignoring the lighter Euro wind field.

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 strong baroclinic zone will be present across the state. The vertical profile shows a deep warm sector ahead of the front with 850mb temps near +8C, crashing toward 0C immediately following the surface boundary.

Thermal Boundary

The cold front is expected to cross I-65 between 10Z and 12Z, clearing the eastern border by 18Z.

Diurnal Trend

Non-diurnal. Temperatures will peak in the morning or early afternoon before the frontal passage, then tumble throughout the remainder of the day.

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 wind shift from SW to NW with gusts increasing to 25-30 mph immediately behind the front.

Jet Stream Support

Excellent lift provided by the right-entrance region of a 160-170 kt jet at 250mb.

Energy Status

A compact shortwave trough is pivoting through, with a focused vorticity peak over Northeast Kentucky around mid-morning.

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

Saturated column in the east; significant dry layer below 700mb in the west will result in virga.

Precipitation Character

Stratiform rain in the east; largely non-measurable sprinkles or virga in the west.

Flooding Context

No flooding risk; totals will be under 0.25" in the wettest regions.
