AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CLEVELAND OH
940 AM EDT TUE JUL 6 1999

SATELLITE IMAGERY INDICATES CLOUDS ASSOCIATED WITH THE FNT ARE
QUICKY DISSIPATING. CONVECTION THAT WAS FIRING ALONG THE FRONT HAS
ALSO QUICKLY DISSIPATED.  SHORTWAVE MOVING OFF TO THE E ACROSS THE
CENTRAL GREAT LAKES REGION IS BECOMING MORE ELONGATED AND WEAKENING
WITH TIME CAUSING CONVECTION TO DIE OFF.  CONVECTION ON THE SOUTHERN
END OF THE FNT WAS BEING DRIVEN BY SUPPLY OF MSTR FM THE GULF OF
MEXICO INTO THE AXIS OF CONVERGENCE. HOWEVER...MSTR SUPPLY HAS BEEN
CUT OFF AND THEREFORE THE CONVECTION HAS WEAKENED.

NOW...IT IS JUST WAIT AND SEE AS THE THE CDFNT PROGRESSES E INTO
INCREASINGLY MORE UNSTABLE AIR MASS OVR OH AND NW PA.  CONVECTION
THAT DOES FIRE WILL BE DRIVEN BY DAY TIME HEATING AND LIFTING
MECHANISM OF THE FNT. LI INCREASE TO -6 SOUTH OF CLE TO ASHTABULA
LINE LATER THIS AFTERNOON. THIS FITS WELL WITH GREATEST HEATING AND
INSTABILITY.  MODEL SOUNDINGS SUPPORT THE POTENTIAL FOR SLOW MOVING
CELLS FM SW TO NE ALONG THE FNTL BOUNDARY AS THE FNT TAKES ON A MORE
W TO E ORIENTATION. HIGHEST CHANCE POPS LIKELY IN EASTERN SECTIONS.

WILL LEAVE CURRENT FORECAST AS IT IS.

.CLE...NONE.
