...SYNOPSIS...
A SHORTWAVE TROUGH WILL MOVE SEWD ACROSS THE OH VALLEY DURING THE
DAY...AND WILL CONTINUE INTO THE APPALACHIANS BY 12Z MON. AT THE
SURFACE...A LOW PRESSURE TROUGH WILL FORM OVER THE CNTRL AND ERN
CAROLINAS...WHERE STRONG HEATING WILL HELP TO PRODUCE UNSTABLE
CONDITIONS. SCATTERED THUNDERSTORMS WILL BE LIKELY FROM ERN GA INTO
SC AND SRN NC...AND SOME STORMS COULD BE SEVERE.

THE SURFACE FRONT WILL TRAIL SWWD ALONG THE CNTRL GULF
COAST...BECOMING QUITE DIFFUSE OVER CNTRL TX. ISOLATED STORMS MAY
OCCUR ANYWHERE ALONG THIS BOUNDARY...BUT THE SEVERE THREAT IS
MINIMAL IN THESE AREAS DUE TO WEAK FORCING AND WINDS ALOFT.

...ERN SC...ERN GA AND SRN NC...
MOST OF THE DAY WILL BE FREE OF THUNDERSTORMS...ALLOWING FOR FULL
HEATING AND STEEPENING LOW LEVEL LAPSE RATES. CONVERGENCE SHOULD BE
MAXIMIZED NEAR THE LOW PRESSURE TROUGH AND ALSO ALONG THE SEA BREEZE
ESPECIALLY OVER ERN SC AND SRN NC. WITH INCREASING WIND SPEEDS WITH
HEIGHT...HODOGRAPHS WILL BE SUFFICIENT FOR SUPERCELLS...PERHAPS
SPLITTING. LARGE HAIL WILL BE THE MAIN THREAT DURING THE LATE
AFTERNOON AND EARLY EVENING BEFORE STORMS MOVE OFFSHORE.
