   ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF NEW ENGLAND AND
   THE MID-ATLANTIC...
   
   ...NEW ENGLAND/MID-ATLANTIC STATES...
   RADAR CURRENTLY SHOWS A SEVERE CONVECTIVE LINE MOVING EWD AT ABOUT
   40 KT ACROSS WRN NY AND WRN PA. THE NARROW LINE OF STORMS IS BEING
   SUPPORTED BY A FOCUSED BAND OF STRONG LARGE-SCALE ASCENT EVIDENT ON
   WATER VAPOR IMAGERY ASSOCIATED WITH AN APPROACHING UPPER-LEVEL
   TROUGH. THE FINE-LINE OF STORMS IS LOCATED JUST AHEAD OF A COLD
   FRONT ALONG THE AXIS OF A STRONG LOW-LEVEL JET. THE VAD WIND
   PROFILER AT BINGHAMTON NY CURRENTLY SHOWS LOW-LEVEL FLOW INCREASING
   WITH 70 KT AT 3 KM AND 50 KT BELOW 1 KM. THIS AMOUNT OF SHEAR
   COMBINED WITH THE FAST MOVEMENT OF THE LINE WILL CONTINUE TO RESULT
   IN A WIND DAMAGE THREAT AS THE LINE MOVES EWD ACROSS THE REGION
   TODAY. IN ADDITION...SFC DEWPOINTS IN THE LOWER 60S F NEAR LONG
   ISLAND WILL RAPIDLY ADVECT NWD INTO ERN NEW ENGLAND RESULTING IN
   DESTABILIZATION ACROSS SRN ME...VT...NH...MA AND RI SUGGESTING THE
   WIND DAMAGE THREAT WILL CONTINUE AS THE LINE MOVES INTO THE
   IMMEDIATE COASTAL SECTIONS LATE THIS AFTERNOON. THE WIND DAMAGE
   THREAT SHOULD BECOME ENHANCED AS INSTABILITY INCREASES AHEAD OF THE
   LINE THIS MORNING AND AFTERNOON WITH A FEW WIND GUSTS OVER 70 KT
   POSSIBLE. THE WIND DAMAGE THREAT WILL LIKELY CONTINUE FOR MOST OF
   THE AFTERNOON UNTIL THE LINE MOVES OFF THE NEW ENGLAND COAST DURING
   THE LATE AFTERNOON OR EARLY EVENING HOURS.
   
   ...SRN ROCKIES...
   AN UPPER-LOW OVER THE FOUR CORNERS REGION EVIDENT ON WATER VAPOR
   IMAGERY WILL BEGIN TO MOVE EWD TODAY INTO THE SRN ROCKIES. ALTHOUGH
   LOW-LEVEL MOISTURE IS NOT VERY ABUNDANT...THE COLD AIR ALOFT AND
   STRONG LARGE-SCALE ASCENT ASSOCIATED WITH THE UPPER-LOW WILL CREATE
   INSTABILITY FAVORABLE FOR CONTINUED THUNDERSTORM DEVELOPMENT THIS
   MORNING AND AFTERNOON. FORECAST SOUNDINGS FOR THIS AFTERNOON ACROSS
   THE REGION SHOW MUCAPE VALUES REMAINING BELOW 500 J/KG WITH 850 TO
   500 MB LAPSE RATES AROUND 7.0 C/KM. ALTHOUGH THIS IS NOT
   EXCEPTIONAL...THE STRONG SHEAR AND COLD AIR ALOFT SHOULD STILL BE
   SUFFICIENT FOR HAIL WITH THE STRONGER CELLS ESPECIALLY IF
   INSTABILITY IS STRONGER THAN FORECAST BY THE MODELS. THE HAIL THREAT
   SHOULD DIMINISH BY EARLY OR MID-EVENING AS INSTABILITY GRADUALLY
   DECREASES ACROSS THE REGION.
