DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
AT 400 AM CDT...0900 UTC...THE CENTER OF BILL WAS LOCATED NEAR
LATITUDE 37.8 NORTH...AND LONGITUDE 87.1 WEST. AFTER SPENDING MORE
THAN THREE DAYS OVER LAND...TROPICAL DEPRESSION BILL CONTINUES TO
MAINTAIN A WELL-DEFINED CYCLONIC CIRCULATION AS IT TRACKS WELL
INLAND OVER SATURATED GROUNDS RESULTING FROM ANTECEDENT HEAVY
RAINS. SATELLITE IMAGERY CONTINUES TO SHOW DECENT CONVECTION
AROUND THE CENTER OF BILL ALONG WITH A PROMINENT UPPER-LEVEL
OUTFLOW PATTERN TO THE NORTH. RADAR IMAGERY AND SURFACE
OBSERVATIONS SHOW A BROAD AXIS OF LIGHT TO MODERATE RAINFALL AHEAD
OF THE CIRCULATION. MEANWHILE...TO THE NORTH OF BILL...A
DEFORMATION ZONE HAS SET UP ACROSS SOUTHERN INDIANA. THIS SHIELD
OF HEAVY RAINFALL HAS BEEN GENERALLY PIVOTING OVER THE SAME
LOCATIONS THE PAST COUPLE OF HOURS. THE CENTRAL PRESSURE HAS
BECOME STEADY DURING THE PAST 6 HOURS AFTER A BRIEF DECREASE THIS
PAST AFTERNOON. RECENT PEAK WIND GUSTS HAVE BEEN IN THE 25 TO 30
MPH RANGE...GENERALLY WITHIN THE SOUTHEASTERN SECTOR OF THE
CIRCULATION. BILL IS EXPECTED TO CONTINUE MOVING
EAST-NORTHEASTWARD UP THE OHIO VALLEY AND INTO THE CENTRAL
APPALACHIANS BEFORE LOSING TROPICAL CHARACTERISTICS.
THEREAFTER...BILL COULD BRIEFLY RESTRENGTHEN WHEN IT MOVES DOWN
THE LEE SIDE OF THE APPALACHIANS ON SUNDAY AS IT GRADUALLY BECOMES
EXTRATROPICAL OVER THE NORTHERN MID-ATLANTIC AND SOUTHERN NEW
ENGLAND COAST.
MAXIMUM SUSTAINED WINDS ARE NEAR 20 MPH...30 KM/H...WITH HIGHER
GUSTS.
MINIMUM CENTRAL PRESSURE IS 1001 MB...29.56 INCHES.
HAZARDS
-------
RAINFALL...BILL IS EXPECTED TO PRODUCE ADDITIONAL 2 TO 3 INCHES OF
RAIN UP ALONG THE OHIO VALLEY INTO WEST VIRGINIA WHILE 1 TO 3
INCHES ARE EXPECTED FARTHER EAST INTO THE NORTHERN MID-ATLANTIC
REGION. THESE RAINS WILL CONTINUE TO ENHANCE THE THREAT FOR FLASH
FLOODING...PARTICULARLY IN REGIONS WHICH ARE ALREADY SATURATED
FROM PREVIOUS HEAVY RAINFALL.
