AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
235 AM EST MON SEP 15 2003

MAIN FACTOR TO WORK WITH IN THE FORECAST ARE THE TEMPERATURES.
TONIGHT THE COLD FRONT HAS MOVED INTO OHIO. THE CLOUDS BEHIND THE
FRONT WERE CONTINUING TO MOVE EAST. BY FORECAST RELEASE TIME THESE
SHOULD BE OUT OF CWA.

CROSS SECTION SHOWS GOOD DRYING OVER AREA. WITH THE RESIDUAL
MOISTURE WE HAD FROM THE RAIN OVER THE WEEKEND MAY GET SOME CU
DEVELOPMENT. WILL GO PARTLY SUNNY DUE TO THIS. MORNING TEMPERATURES
RUNNING A LITTLE HIGHER THEN BOTH GUIDANCE. SINCE THE FRONT WAS
SLOWER MOVING THROUGH THEN THOUGHT COOLER AIR SHOULD BE SLOWER. WILL
GO A LITTLE HIGHER THEN GUIDANCE TEMPS DUE TO THIS.

CROSS SECTIONS SHOW VERY DRY AIR IN ALL LEVELS TONIGHT. WILL GO
CLEAR. THE COOLEST TEMPERATURES ARE USUALLY THE SECOND NIGHT AFTER
FROPA. WILL GO A LITTLE LOWER THEN GUIDANCE TEMPS.

WITH THE DRY AIR REMAINING ON TUESDAY WILL GO MOSTLY SUNNY.
TEMPERATURES INCREASING A FEW DEGREES WITH SOUTHERLY FLOW.
