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.

.PREV DISCUSSION... /ISSUED 307 PM EDT TUE MAR 10 2009/

DISCUSSION...FORECAST FOCUS WILL BE ON THUNDERSTORMS TONIGHT.

TONIGHT...WARM MOIST AIR AHEAD OF A COLD FRONT THAT WAS OVER NW
MISSOURI AT 19Z WILL SET THE STAGE FOR THUNDERSTORM DEVELOPMENT THIS
EVENING. SOME AREAS OF SUN WERE PEEKING THROUGH THE CLOUD COVER
ALLOWING TEMPS TO RISE INTO THE LOW 70S THROUGH MOST OF THE CWA.
INDIANAPOLIS HAS TIED THE MAX TEMP RECORD OF 72 SET IN 1925.  THERE
IS STILL SOME CHANCE FOR SEVERE THIS EVENING SO WILL CONTINUE TO
MONITOR CONVECTIVE POTENTIAL.

BRING SIGNIFICANTLY COLDER AIR IN TONIGHT AND TOMORROW.
WIND WILL PICK UP AHEAD OF THE FRONT AND WIND GUSTS AROUND 40 MPH
ARE POSSIBLE FOR A FEW HOURS AFTER THE FRONT PASSES.

WEDNESDAY...COLD AIR IN THE WAKE OF THE FRONT WILL ONLY ALLOW TEMPS
TO RISE INTO THE UPPER 30S AND LOWER 40S.  CLOUDS WILL CLEAR OUT AND
A SUNNY AND COLD DAY CAN BE EXPECTED.  WEDNESDAY NIGHT WILL BRING
THE COLDEST AIR SOUTH INTO CENTRAL INDIANA.  AREAS FROM LAF-OKK-MIE
WILL SEE TEENS FOR LOWS BUT A NORTH WIND AROUND 10-15 MPH WILL
PREVENT TEMPS FROM DROPPING MUCH LOWER.

THURSDAY THROUGH SATURDAY...HIGH PRESSURE WILL DRIFT EAST AND
TEMPERATURES WILL BEGIN TO REBOUND FROM THE 40S ON THURSDAY TO THE
50S BY SATURDAY.

SATURDAY NIGHT THROUGH TUESDAY...AN H5 LOW WILL MOVE FROM THE SOCAL

MID AND UPPER 50S.
