Another round of severe weather for Kentucky?

Update:  10:54 Friday

The latest runs of the models are still remaining consistent with timing on this system.  The Hi-Res NAM model shows no thunderstorms in the Bluegrass during the day today.  It continues to hold off on any rain until after 2:00 Saturday morning.



By this time, darkness has killed a lot of the dynamics with the atmosphere and the line is in a weakening phase.  What I am expecting is a couple of isolated storms here and there in central KY today...but most places will stay dry.  After midnight, a squall line will move into Kentucky from the northwest.  It'll bring some lightning, gusty winds, and heavy rains...but severe weather will be minimal.  Folks closer to the OH River have a slightly better shot at wind damage.  The Lexington area looks to be OK.

Friday night high school football looks to be in good shape.  We need the rain so I'll be happy to see it come while I sleep.

IF things change I'll update later.  

Take care,

Shawn



Previous post:


The models are slowing the approach of the cold front tomorrow.  Here is the latest Hi-Res NAM depiction:


Notice that no thunderstorms affect central Kentucky until after midnight...and in this model depiction not until after 2:00 AM Saturday morning.  By this time, the instability will be decreasing and the severe threat will be subsiding greatly.

The GFS model supports this idea, but does allow for some isolated storms Friday evening before this main show arrives later.  Keep your eyes peeled Friday afternoon and evening just in case.  But for now, it appears that Friday activities during the evening will not be affected by severe weather.

I’ll update again tomorrow morning.


Take care,


Shawn
