AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
250 AM EDT MON JUN 16 2003

SLOW MOVING THUNDERSTORMS HAVE DEVELOPED THIS MORNING IN DEFORMATION
AXIS OVER SOUTHEAST INDIANA. MEANWHILE...NEARLY STATIONARY SHOWERS
CONTINUE ACROSS PARTS OF THE WHITEWATER AND MIAMI VALLEYS. WEAK 700
MB CONVERGENCE AXIS NOTED ON 00Z ETA IN AREA OF CURRENT ACTIVITY AND
THIS FORECAST TO REMAIN IN PLACE ACROSS MUCH OF SOUTHERN HALF OF FA
THROUGH 21Z BEFORE SHIFTING INTO SE PORTION OF FA TOWARD 00Z. THIS
IN COMBINATION WITH WEAK S/W PROGGED TO PASS ACROSS AREA TODAY AND
DEVELOPING WEAK INVERTED TROF INTO SOUTHERN OHIO SHOULD KEEP THREAT
OF SHOWERS AND THUNDERSTORMS AROUND TODAY. HARD TO PINPOINT EXACTLY
WHERE THINGS MAY DEVELOP SO WILL GENERALLY BROAD BRUSH WITH HIGH
CHANCE POPS ACROSS THE SOUTH...WITH LOWER CHANCE TO THE NORTH. WILL
TRY TO KEEP WAPOK GROUP DRY BUT WILL MONITOR RADAR TRENDS TO MAKE
FINAL DECISION ON THAT BEFORE ZONE ISSUANCE.

EXTREMELY MOIST AIRMASS FORECAST TO REMAIN IN PLACE ACROSS THE AREA
THROUGH TUESDAY WITH PWATS REMAINING IN THE 1.6 TO 1.8 INCH RANGE.
THIS COMBINED WITH VERY LIGHT FLOW THROUGH THE MID LEVELS WILL ONCE
AGAIN RESULT IN VERY SLOW MOVING STORMS WITH VERY HEAVY RAINFALL
POSSIBLE. WILL THEREFORE CONTINUE FLOOD WATCH THROUGH TONIGHT. THINK
BEST CHANCE FOR HEAVY RAIN WILL BE ACROSS THE SOUTH...BUT BASED
ON WHAT HAPPENED ON SUNDAY...WILL ALSO INCLUDE WHITEWATER AND MIAMI
VALLEYS IN WATCH AS IT SHOULD NOT TAKE MUCH RAIN FOR THEM TO SEE
MORE FLOODING.

THINK MODELS MAY BE UNDERDOING QPF FOR TUESDAY WITH FAIRLY STRONG
S/W FORECAST TO PIVOT DOWN ACROSS AREA AND JUICY AIRMASS STILL IN
PLACE. WILL CONTINUE WITH CHANCE POPS FOR NOW BUT THIS MAY
EVENTUALLY NEED TO BE BUMPED UP DEPENDING ON FUTURE MODEL TRENDS.

HIGH TEMPS A LITTLE TRICKY DEPENDING ON HOW MANY CLOUDS AROUND NEXT
FEW DAYS. WILL STICK PRETTY CLOSE TO GUID WITH HIGHS IN THE MID TO
UPPER 70S THOUGH THIS MAY BE TOO WARM IF WE END UP WITH SIGNIFICANT
CLOUD COVER. WILL ALSO TREND LOW TEMPS UP A LITTLE GIVEN MOIST
AIRMASS.
