RIMFIRE CONVECTIVE ELEMENTS AROUND MAINLY OUR WESTERN RIM THRU THE
NEAR TERM FORECAST TIME PERIODS...AND THIS CAN BE SEEN DEPICTED
NICELY ON THE REGIONAL MOSAIC.

HIGH PW'S MARK FOR LOCALLY HEAVY RAINS AS THE PRIMARY HAZARD...NOT
WITHSTANDING ISOLATED WIND GUST (OR HAIL) POTENTIAL IN A
PARTICULARLY STRONGER CELL. QPF THRU FRIDAY SHOULD AVERAGE 1-3
INCHES BUT CLOSER TO 4-5 INCH LOCAL AMOUNTS POSSIBLE FURTHER WEST
CLOSER TO THE TRACK OF BILL. THIS IS ALL HIGHLIGHTED IN THE JUST

MAIN PRECIPITATION AXIS FOR THE REMNANTS OF BILL ARCING ACROSS THE
MIDDLE MISSISSIPPI AND LOWER OHIO VALLEY FRIDAY AND SATURDAY. IN
DISCUSSION WITH PREVIOUS FORECAST SHIFTS AND DECENT MODEL INITIALIZATION
THIS MORNING, THE 06Z/12Z GFS AND NAM-WRF APPEAR TO HAVE A BETTER
HANDLE ON THE EXTRATROPICAL SYSTEM TRANSLATION OF BILL.

SATURDAY SUGGEST AN INCH OR LESS FROM GREENVILLE TO BENTON AND
MURRAY KENTUCKY...TWO INCHES FROM OWENSBORO AND PADUCAH KENTUCKY
TO NEW MADRID MO...THREE INCHES FROM FAIRFIELD ILLINOIS TO
PERRYVILLE MO...WITH NEAR FOUR INCHES POSSIBLE NORTH OF A LINE
FROM MOUNT VERNON TO PINCKNEYVILLE ILLINOIS. THE ANTECEDENT
RAINFALL FROM NOW THROUGH THURSDAY WILL DETERMINE THE EFFECTIVE
SATURATED GROUND STATE FOR FLASH FLOOD/FLOOD POTENTIAL. GIVEN THE
POTENTIAL VARIABILITY AND MESOSCALE INFLUENCES ALONG THE IMPRESSED
DIFFERENTIAL THETA-E BOUNDARY...THE MAIN AXIS OF HEAVY RAIN COULD
VARY BY 25-50 MILES DURING THE NEXT 24-48 HOURS. THE SHORT TERM
FORECASTER CONTINUED THE HYDROLOGICAL OUTLOOK REFERENCING TROPICAL
STORM BILL'S INTERACTION AND INFLUENCE ON RAINFALL AMOUNTS DURING
THE LATER PART OF THE WEEK. AS THE CONE OF UNCERTAINTY DIMINISHES
WITH TIME...A FLASH FLOOD/FLOOD WATCH WILL LIKELY BE NEEDED FOR
PART OF THE WFO PAH FORECAST AREA.

OUTSIDE OF THE RAINFALL, DIURNAL RANGES WILL BE CLOSER TO NORMAL
WITH TEMPERATURES AT 0R SLIGHTLY ABOVE NORMAL FOR THIS TIME OF
YEAR.

INSTABILITY FOR AND SEVERE POTENTIAL (OTHER THAN FLOOD POTENTIAL)
ASSOCIATED WITH CONVECTIVE CLUSTERS MAY BE MINIMIZED BY FRIDAY.
HOWEVER, THE GFS SUGGESTS AN INCREASE A SIGNIFICANT INCREASE OF
DOWNDRAFT CAPE (ABOVE 1000 J/KG2) ON SATURDAY. THIS WILL NEED TO
BE MONITORED FOR SOME WIND POTENTIAL ON SATURDAY.

OTHERWISE, A BRIEF BREAK IN THE RAIN CAN BE EXPECTED FOLLOWING THE
PASSAGE OF BILL...WITH ANOTHER MCS SYSTEM EXPECTED TO MOVE INTO
THE AREA LATE SUNDAY INTO MONDAY.
