What was reported inside it

Time	Report	Where	Remark
Jun 4, 6:13 PM EST	Hail 0.75	Monroe, IN

NCEI Storm Data entries that began inside the alert's area while it was in force. Before 2003 the local storm report archive is thin, so this is the record of what happened rather than what was phoned in.

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.

The watch it was issued in

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
318 PM EST TUE JUN 4 2002

MID LEVEL CAP HAS BEEN WEAKENING...BUT STILL ABLE TO INHIBIT TSTM
FORMATION OVER NRN INDIANA AND NW OH. STNRY FRONT ACRS FAR NRN
INDIANA HAS BEEN A TRIGGER FOR STORMS. STORMS AT 20Z FIRING ALONG
FRONT WEST OF FWA...SO EXPECT DEEPER CONVECTION ALONG FRONT. WILL
KEEP LIKELY OR HIGHER POPS TONIGHT AS FRONT PUSHES SOUTH AS A COLD
FRONT. STILL EXPECT SOME STORMS AND SHOWERS WEDNESDAY AS STILL EXPECT
PCPN BEHIND FRONT...OTHERWISE...SHOULD SEE RAIN ENDING FROM THE NW AS
FRONT MOVES FARTHER SOUTH. GENERALLY USED ETA/AVN MOS AS THESE MODELS
APPEAR TO HAVE A REASONABLE HANDLE ON THERMAL FIELDS AND LOCATION OF
CONVECTION. EXPECT PARTLY CLOUDY CONDTNS THURS AND FRI WITH TEMPS A
LITTLE BELOW NORMAL BEHIND FRONT.

EXTENDED FORECAST
THE BIG CHALLENGE IS WHETHER OR NOT TO ADD PRECIPITATION CHANCES FOR
SUNDAY.  THE AVN MODEL BRINGS A WEAK UPPER TROUGH ALONG THE SOUTHERN
STREAM OF THE JET STREAM ACROSS THE SOUTHERN PLAINS AND THE LOW
MISSISSIPPI VALLEY.  ALTHOUGH THE UKMET AND ECMWF DO NOT READILY
PICK UP ON THIS WAVE...A MOIST SOUTHERLY FLOW AND APPROACHING FRONT
TO THE WEST AS A LOW EJECTS ACROSS THE NORTHERN PLAINS WARRANTS THE
INCLUSION OF POPS ON SUNDAY.  WITH THE UNCERTAIN TIMING OF THIS
FRONT...WE KEPT THE CHANCE FOR POPS IN THE FORECAST ON MONDAY AND
TUESDAY.  LITTLE CHANGES WERE MADE TO THE TEMPERATURES.

.IWX...NONE.
