   DISCUSSION...LONG-LIVED ERN IA SQLN HAS TAKEN ON A NNE-SSW
   ORIENTATION THAT NOW LIES AT A CONSIDERABLE ANGLE TO 60 KT DEEP
   WSWLY FLOW ACROSS REGION PER AREA VWP DATA. GIVEN FACT THAT SQLN
   WILL TRAVERSE A SWATH LARGELY UNTOUCHED BY EARLIER MCS NOW OVER LWR
   MS...AND PERSISTENT LOW-LVL AIRMASS RECOVERY IN NRN IL/FAR SRN WI
   ASSOCIATED WITH MOIST...50 KT SWLY LLJ...SETUP COULD SUPPORT
   MAINTENANCE OF THE SQLN WITH AN ATTENDANT RISK FOR DMGG WIND. IN
   ADDITION...GIVEN STRENGTH OF LOW-LVL SHEAR AND THE LIKELIHOOD FOR
   AUGMENTATION OF SAME ALONG WSW-ENE ORIENTED OUTFLOW BOUNDARY NOW
   OVER NRN IL LEFT BY EARLIER MCS...ENVIRONMENT ALSO COULD PROMOTE
   DEVELOPMENT OF EMBEDDED LOW-LVL MESOCYCLONES/QLCS TORNADOES /REF MCD
