Possibility of Two Lines of Strong to Severe Storms

SPC has us in a SLIGHT RISK for severe weather Saturday Morning-Sunday Morning.

SPC has us in a 30% chance for severe storms Saturday-Sunday morning.  Notice they also have a Hatched Area: 10% or greater probability of significant severe weather within 25 miles of a point, just to our west.

First Round of Storms...

This radar picture was from 9:48 EDT, notice the HUGE line of severe storms stretching from central IL to OK.  This line has already produced large tornadoes near St. Louis and Oklahoma City this evening.  The northern part of this line will make its way towards Kentuckiana by early Saturday morning.  It should weaken as it moves east, but it may still be capable of some strong to severe storms.  With the main threats being wind, heavy rain, hail and lightning and a slight possibility of an isolated tornado. 

The line approaches our western counties between 2-3am.

Metro Louisville between 4-5am.

Southern and SE counties between 6-7am

It looks like we could also see some scattered showers and storms Saturday afternoon.  A few could become locally strong.

Second Line of Storms...

The second line of will arrive with the cold front Saturday night-Sunday morning.  It is possible that thunderstorms on Saturday morning may work over our atmosphere, thus weakening our evening/night instability, and lowering the severe threat.

Bottom Line...  We will need to watch this second line associated with the cold front closely.

Western counties around 2am Sunday.

Metro around 4-5am Sunday.

Southeast counties 7-8am

Stay Tuned... The WHAS11 Storm Team will be watching the storms closely this Crusade weekend!
