MESOSCALE DISCUSSION 0131
   NWS STORM PREDICTION CENTER NORMAN OK
   0722 PM CST THU FEB 24 2011
  
   AREAS AFFECTED…WRN AND SCNTRL KY
  
   CONCERNING…TORNADO WATCH 15
  
   VALID 250122Z – 250245Z
  
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 15 CONTINUES.
  
   AN ISOLATED THREAT FOR TORNADOES ALONG WITH WIND DAMAGE AND HAIL
   WILL BE POSSIBLE EWD ACROSS SCNTRL KY THIS EVENING. A NEW TORNADO
   WATCH WILL BE LIKELY TO THE EAST OF WW 15.
  
   AN INTENSE SQUALL-LINE WITH SEVERAL WELL-ORGANIZED BOW ECHOES IS
   CURRENTLY MOVE QUICKLY EWD ACROSS WRN KY. THE LINE IS ALONG A WARM
   FRONT WHICH EXTENDS EWD ACROSS SRN KY. LOW-LEVEL SHEAR PROFILES ARE
   ENHANCED ALONG THE BOUNDARY WITH THE HOPKINSVILLE WSR-88D VWP
   SHOWING 0-3 KM STORM RELATIVE HELICITIES IN THE 500 TO 600 M2/S2
   RANGE. THIS ALONG WITH LOW LCL HEIGHTS SHOULD BE FAVORABLE FOR
   TORNADOES AS THE SQUALL-LINE MOVES INTO SCNTRL KY OVER THE NEXT FEW
   HOURS. IN ADDITION…A FORWARD SPEED OF THE LINE AT 40 TO 50 KT
   ALONG WITH 50 KT OF FLOW JUST ABOVE THE SFC WILL LIKELY RESULT IN
   WIND DAMAGE.
  
I expect watches to translate east across southern KY tonight.

here is a radar to track the line

Southern Mississippi Valley sector loop

the overall coverage of severe weather should lessen as the line comes east with the highest threat in the BWG region with less of an impact in the Pikeville region.

Stormtoppers will be activating some operations here shortly, Chris Bailey will be updating warnings on a twitter feed www.kentuckyweathercenter.com
