The U.S. National Weather Service in Louisville says that two periods of potentially severe thunderstorms are expected to hit the central Kentucky area beginning in the early morning hours of Thursday, with a second round of potentially severe storms beginning in the afternoon and evening hours of Thursday.
The first round of storms will carry with it heavy rain and lightening, with the second round on Thursday afternoon and evening predicted to bring damaging winds and isolated thunderstorms.
The expected impact of these storms will be winds in excess of 60 mph, which are likely on Thursday evening. Additionally, there is a high potential for the winds to cause damage to trees and weakened structures.
The combination of tree damage from recent icing, and the snow melt the region has experienced, has led to overly soggy ground. Therefore, the high wind threat with the squall line could result in a higher than normal number of trees and branches coming down.
Isolated tornadoes embedded in the squall line will be possible late Thursday afternoon and evening.
Rainfall amounts of one to two inches are anticipated for the area. This amount of rain, coupled with the recent snow melt, may bring about localized flooding in some areas.
Frequent lightening will be possible with the thunderstorm activity late tonight and again on Thursday afternoon.
