NATIONAL WEATHER SERVICE NASHVILLE TN
245 PM CDT THU JUL 23 1998

SCT PULSE TYPE TS ACTIVITY DEVELPING OVER CWA THIS AFTERNOON
WITH MOIST AIRMASS IN PLACE. COLD FRONT ACROSS NORTHERN KY PROVIDING
OUTFLOW BOUNDRIES OVER AREA FOR CONVECTION TO DEVELOP.  WITH THIS
MOIST AIRMASS IN PLACE AND PROGGED SOUTHERLY MOVEMENT OF THE FRONT
...WOULD TEND TO BELIEVE THAT SCT TS/SH ACTIVITY WOULD LAST THRU THE
EVENING AND INTO THE MORNING HOURS. SO WOULD RECOMMEND THE MENTION
OF AT LEAST SCT POPS ALL AREAS. WILL TEND TOWARD FAN NUMBERS HERE.

AS FRONT APPROACHES ON FRI...WOULD RECOMMEND LIKELY POPS FOR
MIDDLE AND WESTERN PORTIONS OF CWA AS BEST DYMANICS FOR
CONVECTIVE DEVELOPMENT PROGGED IN THIS AREA. 500MB TROUGH ALSO
SWINGING THRU REGION WILL HELP IN DEVELOPMENT. SCT POPS OVER
EASTERN PORTIONS OF CWA SUGGESTED.

FOR FRI AND SAT...AS FRONT BECOMES STATIONARY OVER AREA...LOOK FOR
ATMOSPHERIC MOISTURE TO CONTENT TO STILL REMAIN HIGH ENOUGH FOR
THE DEVELOPMEMT OF AFTERNOON SCT SH/TS ACTIVITY...DEPITE NW FLOW
ESTABLISHING ITSELF MORE OVER REGION THRU THE LATER PART OF THE
PERIOD.

AS FOR TEMPS...WILL GO CLOSE TO NGM MOS NUMBERS.
