AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
115 PM CDT WED JUL 29 1998

MAIN FORECAST CONCERN IS HEAVY RAIN/FLOODING POTENTIAL FOR TONIGHT.

KPAH 88D SHOWED LARGE AREA OF RAIN/THUNDERSTORMS HAD MOVED SE AND
OUT OF MOST OF THE PAH FA.  A SMALLER AREA OF -SHRA WAS MOVING SE NR
MISS RIVER AND DECREASING.  LATEST SURFACE ANALYSIS SHOWED DEWPOINTS
IN THE LOWER TO MID 70S ACROSS AREA WITH WEAK SW FLOW.  A WEAK COLD
FRONT EXTENDED WEST TO EAST ACROSS NORTHERN MO AND CENTRAL IL. THIS
FRONT MAY BECOME FOCUS OF NEXT MCS MOVING EAST FROM THE PLAINS.

WEAK SHORT WAVE MOVING ACROSS EASTERN HALF OF FA THROUGH THIS
EVENING MAY KEEP CONVECTION FOCUSED THERE.  NEXT SHORT WAVE PROGGED
FURTHER NORTH CLOSER TO NORTHERN MO/CENTRAL IL FRONT DURING THE AM
HOURS TO MIDDAY THURSDAY.  MOISTURE FIELDS AND BETTER LIFT ALSO
FOCUSED SOMEWHAT FURTHER NORTH.  H8 PRECIPITABLE WATER VALUES SHOW
SOME INCREASE THROUGH THURSDAY MORNING WITH VALUES NEAR 2 INCHES BY
12Z THURSDAY...SO HEAVY RAIN CONCERN CONTINUES OR EVEN INCREASES.
HOWEVER...BELIEVE NORTHWARD SHIFT MAY REDUCE FLOODING CONCERNS
ACROSS THE STRICKEN AREAS OF SE MO.  THERE IS SOME HINT OF A SECOND
FURTHER SOUTHWARD AREA OF CONVECTION WITH A THETA E MAX OVER TN.

MOS TEMP VALUES WERE A TAD HIGH ON LOWS THIS AM OVER THE NE PART OF
THE FA BUT WITH INCREASED CLOUDS TONIGHT FEEL THEY SHOULD BE ON
TARGET FOR TONIGHT.
