AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
910 PM EDT SUN MAY 24 1998

HAVE HAD VERY LITTLE TIME TO LOOK AT THE MODELS THIS EVENING.. I
AGREE WITH THE CURRENT THINKING THAT AFTER TONITE/S CONVECTION THERE
IS ONLY A VERY LOW CHC OF RW/TSTMS UNTIL MON NITE. HOPEFULLY WE/LL
SQUEEZE OUT ONE NICE DAY FOR THE MEMORIAL WEEKEND. AS FOR TONITE...
I/D LIKE TO SEE AT LEAST LOW CHC POPS FOR THE REST OF MY FA OUTSIDE
THE WATCHES. THE LEAST CHC WOULD BE MY NC ZONES...BUT I/D STILL
MENTION- EVEN JUST 20 PCT. DEWPOINTS HV SOARED INTO THE 60S..SO LOWS
TONITE SHUD GO NO LOWER THAN U 50S WHERE THERE IS PCP.
