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.

What forecasters said that day

The local office's own words before this severe thunderstorm 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 severe thunderstorm warning went out at May 2, 3:35 AM CDT, 26 minutes earlier.

Area forecast discussion, May 2, 3:35 AM CDT, 26 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
335 AM CDT TUE MAY 2 2006

.DISCUSSION...
ELEVATED CONVECTION GOT GOING SHORTLY AFTER MIDNIGHT AIDED BY A
40 KNOT LLJ OVER THE AREA. COMPLEX OF STORMS REMAINS ONGOING EARLY
THIS MORNING WITH SEVERAL STRONG/SEVERE STORMS RESULTING IN
SCATTERED HAIL REPORTS THROUGH THE NIGHT. SHOULD EVENTUALLY SEE
THESE STORMS BEGIN TO DIE DOWN LATER THIS MORNING AS LLJ WEAKENS.

FORECAST CONTINUES TO TREND TOWARD UNSETTLED WEATHER THROUGH MUCH
OF THE WEEK. GENERAL FLOW PATTERN WILL REMAIN FAIRLY ZONAL IN THE
MID/UPPER LEVELS WITH SEVERAL WEAK RIPPLES MOVING ACROSS THE AREA.
THIS MORNINGS ACTIVITY WILL POSSIBLY LEAVE A WEAK BOUNDARY BEHIND AS
A FOCUS FOR ADDITIONAL STORMS LATER TODAY...BUT BETTER FOCUS STILL
LIKELY TO BE A DEVELOPING DRYLINE TO THE WEST OF THE AREA BY LATER
THIS AFTERNOON.  STORMS THAT DEVELOP TO THE WEST THIS
AFTERNOON/EVENING ARE THEN EXPECTED TO FORM ANOTHER OVERNIGHT MCS
THAT WILL AFFECT THE AREA.

SAME GENERAL TREND THROUGH MUCH OF THE WEEK WITH SERIES OF UPPER
IMPULSES...COMBINING WITH MOIST/UNSTABLE AMS AND ANY RESIDUAL
BOUNDARIES TO RESULT IN THUNDERSTORM CHANCES EACH DAY AT LEAST
THROUGH FRIDAY. ALSO THE POTENTIAL FOR STRONG/SEVERE STORMS ABOUT
ANY DAY THIS WEEK. WILL STILL TRY TO REMAIN OPTIMISTIC...AND KEEP
THE UPCOMING WEEKEND DRY FOR NOW.
