Breaking Down the Threat
Below are the probabilities for each severe weather threat. Damaging winds carry the highest risk with today’s storms, especially across the western half of Kentucky. That said, all modes of severe weather remain on the table. Tornado probabilities have increased compared to yesterday’s outlook. Similar to recent severe weather events earlier this year, hatched areas (indicated by black dashes) are present. These highlight a 10% or greater chance of significant severe weather, including:
- Damaging winds exceeding 74 mph (hurricane force)
- Hail larger than 2 inches in diameter
- Strong to violent tornadoes
Storms are arriving in waves. The first round is currently moving through the area (as of 9:30 AM). A Severe Thunderstorm Watch is in effect, with storms capable of producing all severe weather hazards—most notably, large hail. This wave will continue pushing east, followed by a lull in activity. That break will allow the atmosphere to “recharge,” increasing instability and setting the stage for another round of severe storms later this afternoon and into the evening/overnight hours.
This second round is expected to be the more significant of the two. Discrete storms are likely to develop initially, posing a greater risk of tornadoes and large hail. As the evening progresses, these storms are expected to merge into a line, shifting the primary threat to damaging straight-line winds.
