I'm issuing a BGP Severe Weather Alert for today Saturday 3/9/19. A portion of western Kentucky is in a Category 3 Enhanced Risk Area for strong to severe storms. This area includes all of western Kentucky west of I-24. A section of Kentucky is in a Category 2 Slight Risk Area. Cities in this area include Madisonville, Bowling Green, Columbia, Louisville, and Owensboro. A Category 1 Marginal Risk Area exist from around the I-75 corridor back west to the Slight Risk Area.

Here is the chart to explain the different categories.

Severe Thunderstorms capable of tornadoes, large hail, and damaging wind gusts are possible across portions of the Mid South today through the early evening. A strong tornado is possible from the confluence of the Ohio and Mississippi Rivers southward into parts of northwest Alabama.

 

There may be a couple of lines of storms from this afternoon into the evening hours. The first looks to be in western Kentucky this afternoon and traverse eastward across the state. A second line could form around 7 pm EST around the I-65 corridor and move eastward. The favorable conditions for severe storms should lessen by then but they will still be there.

 

NAM 3km radar. The timing is from 1 pm EST Saturday to 4 am EST Sunday morning.

I will try to update when I can later today. I have to attend the funeral of the sister of a friend of the family this afternoon. Everyone should be weather aware later today. Especially those in the areas mentioned above.
