Dry and Chilly: Powerful Jet Stream Maintains Gray Skies

A dry but cloudy pattern will hold across Kentucky as a high-velocity jet stream passes overhead. While precipitation is unlikely, a sharp temperature gradient will persist from north to south.

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

Extremely high confidence in a dry forecast across all 12 regions due to the lack of moisture in the column. Lower confidence on exact cloud clearing times and afternoon highs in the south.

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 saturation occurs faster than modeled, a few stray flurries or 'frozen' drizzle (virga reaching the ground) could impact the Northeast and Northern Kentucky valleys.

💨

The 'Bust' Scenario

If the GFS subsidence wins and the 'dry slot' clears out the mid-level moisture, the state could see a much sunnier and slightly warmer afternoon than currently forecast.

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 Southern Warmth Gradient

The GFS is significantly warmer in the southern tier, pushing 50°F, while the NAM keeps those regions in the mid-40s.

GFS
VS
NAM
Why GFS Wins

The GFS typically handles surface temperature recovery in zonal return-flow scenarios better than the mesoscale NAM, which can be too slow to erode shallow cold pools.

Affected Regions
BARREN RIVERSOUTHWEST PENNYRILELAKE CUMBERLAND

The Cloud Cover Conflict

The GFS is aggressively clear (sunny) across the state, while the NAM and Euro suggest a saturated 850-700mb layer will keep skies overcast.

GFS
VS
NAM
VS
EURO
Why EURO Wins

High-velocity jet streaks typically generate significant mid-to-high level cloudiness (cirrus/altostratus) that global models like the GFS often under-forecast in high-pressure regimes.
