Blustery and Unseasonably Mild; Dry Conditions Persist

A powerful upper-level jet streak will cross the Commonwealth on Tuesday, resulting in very windy conditions statewide. Despite the strong atmospheric energy and widespread cloud cover, a parched lower atmosphere will prevent any measurable precipitation from reaching the ground. Temperatures will remain 15 to 20 degrees above seasonal norms.

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

Strong model consensus exists regarding the lack of measurable precipitation and the presence of an unusually strong jet streak. Disagreement is limited to minor variances in peak wind gust speeds and afternoon high temperatures.

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 boundary layer mixes more efficiently than anticipated, wind gusts could exceed 45 mph, and temperatures could reach the mid-60s in the Purchase and Pennyrile regions should clouds thin out earlier.

💨

The 'Bust' Scenario

If the NAM's cooler thermal profile and denser cloud cover verify, high temperatures may struggle to reach the mid-50s, and wind gusts would likely remain below 35 mph due to limited surface-to-aloft momentum transfer.

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 Mixing Match

The NAM is significantly more aggressive with surface wind gusts, projecting values over 40 mph, whereas the Euro and GFS are more conservative with gusts in the low 30s.

NAM
VS
GFS
VS
EURO
Why NAM Wins

In high-velocity jet streak patterns, the NAM's higher resolution typically captures the mechanical mixing of low-level momentum more accurately than global models.

Affected Regions
BLUEGRASS COREPURCHASELOUISVILLE METROLINCOLN TRAIL

The Thermal Ceiling Clash

The GFS is an outlier on the high end of temperatures, suggesting low 60s for much of the state, while the NAM suggests the cloud deck will keep highs capped in the low 50s.

GFS
VS
NAM
Why BLEND Wins

While GFS handles warm-air advection well, it likely underestimates the thermal dampening effect of the 100% cloud cover shown by the Euro and NAM.

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

The vertical temperature stack is characterized by a well-mixed boundary layer and a standard adiabatic lapse rate. Surface temperatures in the 50s and 60s correlate with 850mb temperatures of +8C to +10C.

Thermal Boundary

A moisture-starved cold front will enter Western Kentucky around 15Z and push east of I-75 by 21Z, followed by a slight wind shift but little immediate temperature drop.

Diurnal Trend

The diurnal curve will be heavily muted in the morning due to widespread cloud cover, followed by a non-diurnal clearing trend in the evening.

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 dry cold front will pass through during the afternoon, evidenced by a wind shift from 210 degrees to 280 degrees and a tightening pressure gradient.

Jet Stream Support

Exceptional support from a 250mb jet streak peaking at 176 mph will provide strong upper-level divergence across the northern half of the state.

Energy Status

A broad wave of positive vorticity advection will pivot through, but without a moisture tap, it only results in mid-level cloudiness.

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 atmospheric column is saturated above 15,000 feet, but critically dry air remains below 700mb, creating a high virga risk.

Precipitation Character

Any hydrometeors will be stratiform in nature but are expected to evaporate before reaching the surface.

Flooding Context

No hydrologic concerns exist as the ground is receptive and zero QPF is forecast.

Severe Risk

Instability & Shear

Atmospheric ingredients required for severe thunderstorms, including available fuel (CAPE) and storm organization (shear).

Shear Analysis

Deep layer shear is extremely high (>60kts) due to the low-level response to the jet streak, though it lacks a convective trigger.

Instability Context

CAPE is effectively zero statewide, preventing any thunderstorm development.

Primary Threat

The primary threat is non-convective wind gusts reaching 35-42 mph.
