   ...NO SVR TSTM AREAS FORECAST...
   
   ...SRN ATLANTIC COAST...
   NUMEROUS STORMS ARE CURRENTLY ONGOING ACROSS THE CAROLINAS...GA AND
   FL. THE CONVECTION IS PARTIALLY IN RESPONSE TO SFC HEATING AND WEAK
   FORCING DUE TO AN ERN US UPPER-LEVEL TROUGH. THE STORMS ARE FORMING
   NEAR AND ALONG A FRONTAL BOUNDARY THAT EXTENDS SW TO NE FROM CNTRL
   GA TO ERN NC. OBJECTIVE ANALYSIS SHOWS MODERATE INSTABILITY PRESENT
   ALONG AND SOUTH OF THE BOUNDARY WHERE SFC DEWPOINTS ARE IN THE 70S
   F. IN ADDITION...VAD WIND PROFILES ACROSS THE REGION SHOW 0-6 KM
   SHEAR VALUES OF 15 TO 20 KT SUGGESTING ANY SEVERE THREAT WILL REMAIN
   MARGINAL. MOIST PROFILES AND STEEP LOW-LEVEL LAPSE RATES SHOULD
   FAVOR ISOLATED WIND DAMAGE WITH THE STRONGEST CELLS. ANY SEVERE
   THREAT WILL LIKELY DIMINISH BY EARLY EVENING DUE TO LOSS OF SFC
   HEATING.
   
   ...UPPER MIDWEST/NRN PLAINS...
   A SHORTWAVE IS CURRENTLY MOVING ACROSS SRN SD AROUND THE NERN END OF
   A SWRN US UPPER-LEVEL RIDGE. LIFT AHEAD OF THIS FEATURE IS
   SUPPORTING SCATTERED ELEVATED STORMS ONGOING IN ERN NEB. AS THE
   ASCENT SPREADS EWD ACROSS IA LATE THIS AFTERNOON...SFC-BASED STORMS
   MAY INITIATE ALONG A STATIONARY FRONT WHERE MLCAPE VALUES RANGE FROM
   1000 TO 1500 J/KG. IN ADDITION...PROFILERS ACROSS THE REGION SHOW 20
   TO 30 KT OF VERTICAL SHEAR SUGGESTING A FEW CELLS MAY APPROACH
   SEVERE LIMITS THROUGH EARLY EVENING. HAIL AND ISOLATED WIND DAMAGE
   WOULD BE POSSIBLE IF SFC-BASED STORMS DEVELOP BUT THE SEVERE THREAT
   SHOULD REMAIN MARGINAL.
   
   FARTHER WEST IN THE BLACK HILLS...A FEW STORMS MAY INITIATE LATE
   THIS AFTERNOON AND/OR THIS EVENING. THE CELLS COULD BRIEFLY BECOME
   SEVERE DUE TO THE MODERATE DEEP LAYER SHEAR AND STEEP MID-LEVEL
   LAPSE RATES IN PLACE. HOWEVER...WEAK LARGE-SCALE ASCENT AND
   RELATIVELY WEAK INSTABILITY SHOULD KEEP ANY SEVERE HAIL THREAT BRIEF
   AND MARGINAL.
   
   ...SW DESERTS...
   AN UPPER-LEVEL HIGH IS CURRENTLY ANCHORED OVER THE CNTRL ROCKIES
   WHICH IS TRANSPORTING MONSOONAL MOISTURE NWD ACROSS THE SW DESERTS.
   THE MID-LEVEL MOISTURE COMBINED WITH SFC HEATING HAS RESULTED IN
   SCATTERED STORM INITIATION IN THE HIGHER TERRAIN OF SRN CA...AZ AND
   NV. THE STORMS WILL CONTINUE TO INITIATE LATE THIS AFTERNOON AND
   DRIFT NWD INTO THE DESERTS THROUGH THIS EVENING. VAD WIND PROFILES
   ACROSS THE REGION CURRENTLY SHOW RELATIVELY WEAK 0-6 KM SHEAR
   PROFILES SUGGESTING ANY SEVERE THREAT WILL REMAIN DISORGANIZED.
   HOWEVER...LARGE TEMP-DEWPOINT SPREADS AND STEEP LOW-LEVEL LAPSE
   RATES MAY BE ENOUGH FOR AN ISOLATED WIND DAMAGE THREAT WITH THE
   STRONGEST STORMS.
