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 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 Jan 12, 5:22 PM CST, 1 hour 32 minutes earlier.

Area forecast discussion, Jan 12, 5:22 PM CST, 1 hour 32 minutes before

EASTERN OKLAHOMA/NORTHWEST ARKANSAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OKLAHOMA
522 PM CST WED JAN 12 2005

...MESOSCALE UPDATE...

BACKED DEEP-LAYER SHEAR IS PROMOTING CELL-TO-CELL INTERACTIONS AND
RESULTING IN DECREASED POTENTIAL FOR DESCRETE SUPERCELLS.  AS THE
STONGER FORCING APPROACHES FROM THE WEST A COMPLETE EVOLUTION TO A
SCQUALL LINE WILL OCCUR.  WITH LIMITED INSTABILITY...THE SEVERE
THREAT IS QUICKLY EVOLVING TOWARD SPORADIC DAMAGING WIND REPORTS.
HOWEVER...0 TO 1 KM SHEAR REMAINS VERY HIGH IN WESTERN ARKANSAS AND
THE EASTERN TIER OF OKLAHOMA COUNTIES...SO AN ISOLATED TORNADO FROM
A BOWING LINE SEGMENT / EMBEDDED SUPERCELL REMAINS POSSIBLE.

WHILE LINE SEGMENTS ARE MOVING QUICKLY...THE OVERALL EASTWARD
PROGRESS OF THE LINE WILL BE LESS...SO THAT A FLASH FLOOD WATCH MAY
BE NEEDED SOON FOR AREAS NEAR AND AHEAD OF THE LINE.

FORECAST ID= 08

.TSA WATCHES/WARNINGS/ADVISORIES...

...SEVERE THUNDERSTORM WATCHES AND A FLASH FLOOD WATCH IS IN EFFECT
FOR MOST OF THE REGION...

THIS OUTLOOK IS FOR NORTHWEST AND WEST CENTRAL ARKANSAS AS WELL AS
MUCH OF EASTERN OKLAHOMA.

.DAY ONE...TODAY AND TONIGHT
TORNADO.
	RISK...LIMITED.
	AREA....WESTERN ARKANSAS AND EXTREME SOUTHEAST OKLAHOMA.
	ONSET....ONGOING...ENDING AROUND 11PM.

SEVERE THUNDERSTORM.
	RISK...SIGNIFICANT.
	AREA...WESTERN ARKANSAS AND EASTERN OKLAHOMA...EAST OF
               HIGHWAY 75.
	ONSET...ONGOING...ENDING AROUND 11PM.

	AREA AT GREATEST RISK...WESTERN ARKANSAS AND THE EASTERN MOST
                                OKLAHOMA COUNTIES.

FLASH FLOOD.
	RISK...ELEVATED.
	AREA...WESTERN ARKANSAS AND EASTERN OKLAHOMA EAST OF A GROVE TO
               HUGO LINE.
	ONSET...ONGOING...ENDING AROUND MIDNIGHT.

DISCUSSION...
THE PRIMARY SEVERE WEATHER AND FLOODING THREAT IS IN ASSOCIATION
WITH THE SQUALL LINE THAT WAS MOVING FROM OKLAHOMA INTO ARKANSAS.
THERE REMAINS SOME CHANCE OF THUNDERSTORM DEVELOPMENT WEST OF THIS
ACTIVITY AS THE MAIN STORM SYSTEM APPROACHES FROM THE WEST.  WHILE
SEGMENTS OF THE LINE WILL MOVE RAPIDLY...THE EASTWARD PROGRESS OF
THE LINE WILL BE SLOWER AND WILL RESULT IN SOME FLASH FLOOD
POTENTIAL.  IN ADDITION...DESPITE RATHER WEAK INSTABILITY STRONG
LOW-LEVEL WINDS JUST ABOVE THE SURFACE MEANS THAT THERE WILL BE THE
POTENTIAL FOR SPORADIC DAMAGING WIND GUSTS WITH THE STORMS.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
SPOTTERS AND EMERGENCY MANAGERS IN THE AREA SHOULD REMAIN ACTIVATED
UNTIL ALL WATCHES AND WARNINGS ARE DISCONTINUED IN THEIR AREA.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.
THURSDAY THROUGH TUESDAY....NO HAZARDS.

EXTENDED DISCUSSION...
LATEST COMPUTER MODELS INDICATE THAT THE ARCTIC AIR THAT HAD BEEN
FORECAST TO MOVE THROUGH THE REGION WILL BE LESS INTENSE AND JUST
GLANCE THE AREA...THEREFORE THE THREAT OF DANGEROUS WIND CHILLS HAS
BEEN REMOVED FROM THE EXTENDED FORECAST.
