Area forecast discussion, Sep 1, 8:55 PM EDT, 4 hours 53 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG, VA 855 PM EDT FRI SEP 1 2000 THUNDERSTORM COVERAGE HAS BEEN DECREASING ACROSS THE FA PAST FEW HOURS. HOWEVER...THE 00Z RNK SOUNDING STILL SHOWS A TROPICAL LOOKING AIRMASS...WITH A CAPE AROUND 1000 J/KG. BOUNDARY LAYER WINDS ARE STILL FROM THE EAST...WHILE THERE IS NOW MORE OF A SOUTH FLOW ABOVE. THIS IS A GOOD WIND PROFILE FOR BACK-BUILDING STORMS...AS WE HAVE BEEN SEEING ON RADAR. NOT MUCH OF ANY STRONG FEATURE SEEN TO INITIATE CONVECTION OVERNIGHT...SO CURRENT FCST OF CHC POPS IS PROBABLY BEST FOR MOST OF THE FA. THE 18Z MESO-ETA DID A GOOD JOB YESTERDAY OF SHOWING THE LOCATIONS FOR LARGE SCALE LIFT LAST NIGHT...MAINLY CORRESPONDING TO UPPER LEVEL DIVERGENCE. TONIGHT IT IS INDICATING THE BEST LIFT OVER THE NW PIED AND FOOTHILLS OF NC. WILL PROBABLY RAISE POPS TO LIKELY DOWN THAT WAY. .RNK... NC...NONE. VA...NONE. WV...NONE. JJX
