   ...SYNOPSIS...
   THE REMNANTS OF TROPICAL STORM JEANNE WILL MOVE ENEWD ACROSS CENTRAL
   AND ERN NC DURING THE DAY.  AN INFLUX OF MARITIME TROPICAL AIR IN
   ADVANCE OF THE SURFACE LOW WILL CONTRIBUTE TO SUFFICIENT INSTABILITY
   FOR DEEP CONVECTION...WHILE VERTICAL SHEAR SHOULD REMAIN STRONG
   ENOUGH TO SUPPORT AT LEAST SOME THREAT OF SUPERCELLS WITH A TORNADO
   OR TWO...AND PERHAPS STRONG WIND GUSTS. STILL...VERTICAL SHEAR WILL
   BE WEAKENING WITH TIME ACROSS ERN NC AND INSTABILITY WILL NOT BE
   PARTICULARLY STRONG...SO THE SEVERE THREAT APPEARS TO BE A LITTLE
   TOO MARGINAL FOR A SLIGHT RISK AT THIS TIME.
   
   ELSEWHERE...A SPLIT FLOW REGIME WILL PERSIST WITH THE STRONGER NRN
   STREAM EXPECTED TO REMAIN OVER CANADA AND NRN NEW ENGLAND...AND A
   WEAKER SUBTROPICAL STREAM INVOF THE U.S./MEXICO BORDER.  WITHIN THE
   SRN STREAM...THE MAIN FEATURE OF INTEREST WILL BE AN AMPLIFYING MID
   LEVEL TROUGH OVER SRN CA/LOWER CO RIVER VALLEY.  L0W-LEVEL MOISTURE
   WILL BE LIMITED IN ADVANCE OF THIS SYSTEM...BUT PERSISTENT ASCENT
   AND ASSOCIATED MID LEVEL MOISTENING NEAR THE RIM IN AZ SHOULD
   SUPPORT SCATTERED HIGH-BASED THUNDERSTORMS BY TOMORROW EVENING. 
   WEAK INSTABILITY WILL TEND TO LIMIT ANY SEVERE THREAT THIS AREA. 
   OTHER MORE ISOLATED /MAINLY DIURNAL/ THUNDERSTORMS WILL BE POSSIBLE
   ACROSS A BROAD AREA OF THE INTERMOUNTAIN WEST IN ASSOCIATION WITH
   STEEP L0W-MID LEVEL LAPSE RATES AND WEAK BUOYANCY.
