VALID 110021Z - 110115Z

SQUALL LINE HAS DEVELOPED ALONG LEADING EDGE OF OLD MCS THAT MOVED
ACROSS OK/AR EARLIER TODAY.  THIS ACTIVITY HAS EVOLVED WITHIN A
NARROW AXIS OF INSTABILITY THAT HAS YET TO BE OVERTURNED ALONG THE
MS/AL BORDER INTO EXTREME SRN TN.  LATEST RADAR TRENDS SUGGEST
BOWING STRUCTURE IS MOVING ENEWD AT ROUGHLY 35 KT WHILE TRAILING
CONVECTION IS ADVANCING EWD SOMEWHAT SLOWER ACROSS NRN MS.  IT
APPEARS THERE IS SOME THREAT FOR ISOLATED DAMAGING WINDS ALONG
LEADING EDGE OF BOW AS IT MOVES INTO NWRN AL/SRN TN.  LOSS OF
DAYTIME HEATING AND MARGINAL INSTABILITY DOWNSTREAM INTO NERN
AL/MIDDLE TN SUGGEST THIS THREAT WILL REMAIN LOCAL AND ONLY FOR THE
NEXT FEW HOURS.
