Windy and Warmer: A Strong Rebound Under Sunny Skies

Kentucky will experience a significant warming trend today as high pressure shifts east and a strong southerly wind develops. Despite a cold start, temperatures will climb into the 50s for most of the state. It will be a very windy day, but precipitation is not expected.

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

High agreement between GFS, NAM, and GEM on the dry and warm solution; however, the extreme outlier status of the ECMWF creates a significant statistical disagreement penalty.

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 mid-level moisture returns faster than modeled, a few patches of virga or light sprinkles could reach the ground in the Purchase region late this evening, though no accumulation would occur.

💨

The 'Bust' Scenario

If the boundary layer mixes more deeply than forecast, wind gusts could exceed 45 mph in the Bluegrass and Foothills regions, potentially leading to localized minor tree or limb damage.

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 Phantom Blizzard of January

The ECMWF is an extreme outlier, predicting a historic 10-20 inch snowstorm with 7-10 inches of liquid equivalent. The GFS, NAM, and GEM all show a dry, warm day with highs in the 50s.

ECMWF
VS
GFS
VS
NAM
Why BLEND Wins

The ECMWF's liquid totals are non-physical and climatologically impossible for this setup (7 inches of liquid in 6 hours). The synoptic consensus among all other global and mesoscale models supports a dry, windy, warm sector environment.

Affected Regions
PURCHASELOUISVILLE METRONORTHERN KYBLUEGRASS CORE

Boundary Layer Momentum Transfer

Models disagree on how much of the 850mb LLJ will mix down to the surface. The NAM is more aggressive with 40mph+ gusts, while the GEM is more conservative.

NAM
VS
GEM
VS
GFS
Why NAM Wins

The NAM tends to resolve sharp pressure gradients and momentum transfer better in high-wind WAA setups within the 24-hour window.

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 surface inversion will break by 15z, giving way to a nearly dry-adiabatic lapse rate in the lowest 2km. 850mb temps will climb from 2C to 8C.

Thermal Boundary

The 0C surface isotherm will retreat well north into Central Indiana and Ohio by midday.

Diurnal Trend

Standard diurnal curve with a rapid 20-25 degree rise following the erosion of the morning radiation inversion.

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

No frontal passage. The region remains in the deepening pressure gradient between a departing high and a lee cyclone.

Jet Stream Support

Kentucky is in the right-entrance region of a 250mb jet, but the lack of moisture prevents any development.

Energy Status

Broad cyclonic flow aloft with weak vorticity advection manifest only as high-level cirrus.

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

Extremely dry. Surface dewpoint depressions of 20-30F are expected during peak heating.

Precipitation Character

None. Dry air will evaporate any localized moisture (Virga risk only).

Flooding Context

Zero risk. Ground is dry and receptive.
