A Dramatic February Thaw After a Frigid Start

Kentucky will experience a sharp temperature recovery on Monday as arctic high pressure shifts toward the Atlantic coast, opening the door for breezy southwesterly winds. While the day begins with a deep freeze—and even a few flurries in the northeast—afternoon sunshine will push temperatures into the 50s and low 60s for most of the Commonwealth.

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

Confidence is high for a dry and sunny afternoon, but low regarding the exact morning minimums and the speed of the temperature recovery in the northern tier.

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: If the GEM's arctic persistence verifies, the cold pool remains trapped in the northern valleys, keeping highs in the 30s for the Bluegrass and Northern KY, while flurries in the northeast lead to a persistent dusting on grassy surfaces.

💨

The 'Bust' Scenario

The 'Bust' Scenario: If the GFS warming magnitude wins, the thermal recovery is even more aggressive, with 60-degree temperatures surging as far north as Louisville and Lexington under completely clear skies.

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.

Northeast Clipper Moisture

The GEM predicts a weak shortwave will trigger early morning snow showers in the Northeast, while the GFS and Euro maintain a dry column.

Why GEM Wins

The GEM typically resolves these shallow, moisture-starved winter clippers better than global models, which often 'smear' light precipitation out of existence.

Affected Regions
NORTHEAST KY

The Arctic Scour Conflict

A significant disagreement exists regarding how quickly the morning arctic airmass is scoured out. The GFS is very aggressive with the warm-up, while the GEM holds onto sub-freezing air in the north and east through the early afternoon.

Why EURO Wins

The Euro provides a realistic middle-ground, acknowledging the strength of the return flow seen in the GFS but respecting the shallow density of the arctic airmass identified by the GEM.

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 morning subsidence inversion will be in place with a very cold surface layer (teens/20s) and warmer air aloft. This inversion will break by 15z-17z, allowing for a standard adiabatic lapse rate and rapid surface warming.

Thermal Boundary

The 32F freezing line will start south of the Bluegrass Parkway at dawn but will be pushed north of the Ohio River by early afternoon.

Diurnal Trend

A highly non-diurnal curve is expected in the west, where temperatures will jump over 30 degrees in an 8-hour window due to robust solar loading and WAA.

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 surface front will pass. The primary driver is the clockwise circulation of the departing high and the tightening gradient ahead of lee-side cyclogenesis in the Plains.

Jet Stream Support

Kentucky remains in the right-rear quadrant of a 110kt jet streak over the Great Lakes, providing weak synoptic lift that will only result in high-level cirrus.

Energy Status

Vorticity is low statewide except for the departing shortwave in the northeast, which provides brief mid-level ascent before 12z.

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 column is exceptionally dry with PWATs below 0.30 inches. Large dewpoint depressions at the surface (20F+) will maintain high visibility.

Precipitation Character

Expect a brief window of stratiform flurries or light snow in the far northeast early; otherwise, conditions will be dry.

Flooding Context

No hydrologic risk as precipitation is negligible and the ground remains relatively dry or frozen.
