The radar

The Tulsa radar (KINX), 52 km from the middle of the area, began a volume at 20:45 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood 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 nearest sounding before it

Norman, OK (KOUN), launched 12:00Z, 8.7 hours before the alert went out and 182 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

What forecasters said that day

The local office's own words before this flash flood 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 flash flood warning went out at Jul 10, 3:40 PM CDT, 3 minutes earlier.

Area forecast discussion, Jul 10, 3:40 PM CDT, 3 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
340 PM CDT THU JUL 10 2014

.DISCUSSION...
EARLY MORNING MCS COMBINED WITH CONTINUAL CONVECTION ON WESTERN
PERIPHERY OF THE SYSTEM COLD POOL HAVE YIELDED WIDESPREAD RAINS FOR
AREAS NORTH OF INTERSTATE 40 TODAY. FURTHER SOUTH ACROSS SOUTHEAST
OKLAHOMA CONDITIONS REMAIN STRONGLY UNSTABLE...AND FURTHER
CONVECTION MAY YET DEVELOP ACROSS THIS REGION INTO THE EARLY EVENING
HOURS. THEREAFTER...ANY OVERNIGHT STORMS WILL TEND TOWARD THE
ELEVATED FRONTAL ZONE WHICH WILL CONTINUE TO LIFT NORTHEASTWARD AND
EVENTUALLY CLEAR THE FORECAST AREA.

THE RETURN TO HOT AND HUMID WEATHER WILL BEGIN FRIDAY AND PEAK ON
SUNDAY FOR MUCH OF THE AREA. THE WIDESPREAD RAINS RECEIVED TODAY
WILL LIKELY TEMPER THE HEAT NORTH OF INTERSTATE 40 HOWEVER TRIPLE
DIGIT HEAT IS LIKELY BY SUNDAY AS LOW LEVEL WINDS VEER AND THERMAL
AXIS IS MAGNIFIED JUST AHEAD OF THE NEXT COLD FRONT. ANY PRECIP
CHANCES WILL REMAIN VERY LOW THROUGH THE WEEKEND AND BE CONFINED
TO THE HIGHER TERRAIN.

THE INITIAL COLD FRONT AND/OR CONVECTIVE OUTFLOW WILL PUSH INTO
NORTHEAST OKLAHOMA LATE SUNDAY INTO MONDAY...AND GRADUALLY WORK
SOUTHWARD WITH A STRONGER PUSH OF COOLER AND DRIER AIR ON TUESDAY.
THIS BOUNDARY WILL BE A FOCUS FOR SHOWER AND THUNDERSTORM CHANCES
AS IT WORKS SOUTHWARD. THE PATTERN ALOFT BECOMES HIGHLY AMPLIFIED
WITH UPPER RIDGING EXTENDING ALONG THE WESTERN STATES AND PUSHING
NEARLY TO THE ARCTIC CIRCLE. THE DOWNSTREAM UPPER LOW
/#NOTPOLARVORTEX/ WILL HELP DRIVE AN UNSEASONABLY COOL AIRMASS
THROUGH THE CENTRAL AND EASTERN STATES. AVERAGE DAILY TEMPERATURES
SOME 10 TO 20 DEGREES BELOW NORMAL LOOK LIKELY FOR MUCH OF THE
FORECAST AREA FOR MID TO LATE IN THE WORK WEEK.
