EVENT...TRAINING CONVECTION ALONG FRONT
.
SATELLITE ANALYSIS AND TRENDS...SURFACE ANALYSIS PLACES SFC BOUNDARY FROM
S IL E THROUGH N KY THAT HAS PROVIDED SFC CONVERGENCE/FOCUS OF CONVECTION
TO DEVELOP ALONG LAST HOUR OR SO. GOES SOUNDER SHOWS CAPES AS HIGH AS
3000-4000J/KG AND SPC MESOANALYSIS PLACES VERY HIGH INSTABILITY WITH BEST
CAPES APPROACHING 4000 J/KG IN DISCUSSION REGION AND VIS IMAGERY HAS
SHOWN SEVERAL CELL MERGERS/OVERSHOOTING TOPS SUGGESTING EFFICIENT RAIN
PRODUCING STORMS.  BLENDED TPW SHOWS PWATS POOLING ALONG BOUNDARY WITH
PWATS APPROACHING 1.5-1.7" WITH DEEPEST MOISTURE ALONG WESTERN EXTENT
OF BOUNDARY WHERE BACKBUILDING CONVECTION COULD POSE A PROBLEM NEXT FEW
HOURS. WOULD EXPECT RATES OF 1-2"/HR IN MERGERS/DEEPEST CONVECTION THAT
COULD PRESENT FF ISSUES.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
.
SHORT TERM OUTLOOK VALID 2115-0015Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...EXPECT NEW CELL DEVELOPMENT TO CONTINUE ALONG AND
JUST SOUTH OF FRONTAL BOUNDARY WHERE TRAINING/BACKBUILDING COULD PRESENT
FF ISSUES GIVEN THAT 3 HR FFG IS GENERALLY 2.5-3.0". WOULD EXPECT RATES
OF 1-2"/HR IN DEEPEST CONVECTION/MERGERS AND EXPECT THIS TO CONTINUE
FOR AT LEAST THE NEXT 3 HOURS.
