Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

Area forecast discussion, Jul 9, 3:00 PM EST, 4 hours 35 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE INDIANAPOLIS IN
300 PM EST FRI JUL 9 2004

.DISCUSSION...MAIN FOCUS WILL BE ON POPS AND TIMING OF
THUNDERSTORMS NEXT SEVERAL DAYS. LIGHTNING CHART AND RADAR SHOWS A
CLUSTER OF THUNDERSTORMS OVER SOUTHEAST INDIANA AND ANOTHER ONE OVER
NORTHEAST ILLINOIS AND BOTH ARE MOVING EASTWARD.

SURFACE CHART SHOWS SLOW MOVING WARM FRONT FROM SOUTH CENTRAL OHIO
TO JUST NORTH OF KIND AND WEST INTO CENTRAL MISSOURI. A VERY WARM
AND HUMID AIR MASS IS SOUTH OF THE FRONT WITH DEWPOINTS AS HIGH AS
THE MID 70S IN SOME AREAS.

MODELS MOVE WARM FRONT INTO NORTHERN INDIANA OVERNIGHT BUT THEN KEEP
IT QUASI-STATIONARY OVER NORTH CENTRAL INDIANA UNTIL LATE SUNDAY
WHEN IT FINALLY MOVES NORTH INTO THE SOUTHERN GREAT LAKES. EVEN
THOUGH MODELS ARE IN GENERAL AGREEMENT THEIR ARE DIFFERENCES IN
TIMING AND AMOUNT OF PRECIP. BELIEVE CLUSTER OF THUNDERSTORMS OVER
SE INDIANA WILL MOVE EASTWARD THIS EVENING AS INDICATED BY RUC...SO
WILL GO ONLY CHANCE OF THUNDERSTORMS THIS EVENING. AS SHORT WAVE
APPROACHES LATER TONIGHT WILL GO LIKELY POPS NORTHERN TWO THIRDS OF
OUR FORECAST AREA.  MODELS ALSO SHOW GOOD LOW LEVEL CONVERGENCE OVER
NORTHERN ILLINOIS AND HPC SHOWS ISOLATED EXCESSIVE RAIN AMOUNTS ARE
POSSIBLE NEXT 24 HOURS OVER THE NORTHERN HALF OF OUR FORECAST AREA.

WILL CUT TEMPERATURES A FEW DEGREES SATURDAY NORTH AND CENTRAL DUE
TO THUNDERSTORMS. MODELS ARE NOT CLEAR ABOUT DEGREE OF THUNDERSTORM
ACTIVITY FOR SUNDAY...HOWEVER WITH FRONT MOVING NORTHWARD WILL GO
WITH CHANCE CATEGORY FOR NOW.

IN EXTENDED WILL LEAN TOWARDS NCEP SCENARIO WHICH KEEPS FRONT JUST
NORTH OF OUR FORECAST AREA UNTIL DAY 7. WILL MENTION CHANCE OF
THUNDERSTORMS MOST OF THIS PERIOD UNTIL DAY 7.
