Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado 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

What forecasters said that day

The local office's own words before this tornado warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Tulsa, OK wrote its last area forecast discussion before this tornado warning went out at Apr 6, 5:47 PM CDT, 16 minutes earlier.

Area forecast discussion, Apr 6, 5:47 PM CDT, 16 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
547 PM CDT THU APR 6 2006

.MESOSCALE UPDATE...
SUPERCELL IN SOUTHERN WASHINGTON COUNTY IS THE CYCLONIC TWIN OF
THE CELL THAT IS NOW RACING ACROSS NORTHERN WASHINGTON COUNTY ON
A COLLISION COURSE WITH THE SUPERCELL NEAR CANEY KANSAS.

THE CYCLONIC CELL IS OFF THE DRY LINE AND HAS THE
POTENTIAL TO BECOME A DANGEROUS CELL AS ITS MOTION HAS
SLOWED.  IF IT DEVELOPS A RIGHT TURN...IT WILL BE TRACKING
ACROSS NORTHEAST OKLAHOMA WHILE TORNADO PARAMETERS ARE PEAKING.

ADDITIONAL CELLS ARE RAPIDLY DEVELOPING ON THE DRY LINE FROM
WEST OF TULSA TO WEST OF MCALESTER.  BECAUSE OF THE MORE LINEAR
FORCING...IT WILL BE HARDER TO MAINTAIN DISCRETE CELLS WITHIN
THIS ACTIVITY...BUT DEEP-LAYER SHEAR IS HIGH AND SUPERCELLS
WITH EMBEDDED SUPERCELLS ARE EXPECTED.  AS WIND FIELDS OVER SOUTHEAST
OKLAHOMA BEGIN TO EVOLVE...AN INCREASED TORANDO RISK WILL DEVELOP
WITH THIS ACTIVITY WITH TIME.
