The radar

The Tulsa radar (KINX), 93 km from the middle of the area, began a volume at 09:33 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 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.

The nearest sounding before it

Lamont, OK (KLMN), launched 00:00Z, 9.6 hours before the alert went out and 132 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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
354 AM CDT SUN MAY 19 2013

.DISCUSSION...
WELL-ADVERTISED PERIOD OF SIGNIFICANT SEVERE WEATHER BEGINS LATER
TODAY AS A 120 KT JET ANALYZED OVER NRN CA/SRN OR AT 00Z
TRANSLATES SEWRD ACROSS THE SRN ROCKIES INTO THE SRN PLAINS.
ATTENDANT NEGATIVELY TILTED TROUGH ROTATES ACROSS THE REGION LATER
TODAY. LATEST ANALYSES INDICATE VERY STEEP MID LEVEL LAPSE RATES
AND RICH LOW LEVEL MOISTURE ALREADY IN PLACE. DRY LINE ONCE AGAIN
EXPECTED TO SHARPEN THIS AFTERNOON TO OUR WEST WITH THUNDERSTORMS
INITIATING ON IT LATE THIS AFTERNOON. LATEST MODEL DATA SUGGESTS
IT WILL MIX FURTHER EAST THAN YESTERDAY...POSSIBLY NEAR THE I-35
CORRIDOR. CURRENT THOUGHT IS THAT STORMS WILL BEGIN TO AFFECT NWRN
PORTIONS OF ERN OK AFTER 5 PM AS CAP KEEPS SFC-BASED STORMS AT BAY
UNTIL RATHER LATE. VERY UNSTABLE AIR MASS AHEAD OF THE DRY LINE
OVER ERN OK WITH CAPE ON THE ORDER OF 3-4K J/KG AND STRONG DEEP
LAYER SHEAR SHOULD ENSURE RAPID SEVERE THUNDERSTORM DEVELOPMENT.
SUPERCELLS WITH ALL MODES OF SEVERE WEATHER INCLUDING VERY LARGE
HAIL LARGER THAN BASEBALLS AS WELL AS SIGNIFICANT TORNADOES WILL
BE POSSIBLE AS LOW LEVEL SHEAR/HELICITY INCREASES THIS EVENING
ACROSS ERN OK. ALL MODELS HINT THAT CAP WILL LIMIT CONVECTION
THROUGH TONIGHT ACROSS SRN PORTION OF THE REGION. BEST COVERAGE OF
STORMS TONIGHT WILL BE ACROSS NERN OK AND FAR NWRN AR.

SETUP WILL BE QUITE SIMILAR ON MONDAY WITH DRY LINE INITIATING
STORMS DURING THE LATE AFTERNOON. REMNANT OUTFLOW BOUNDARY FROM
TONIGHT'S STORMS WILL ALSO BE A FACTOR FOR STORM REDEVELOPMENT
LATER IN THE DAY WHERE EVER IT SETTLES. VERY UNSTABLE CONDITIONS
WITH STRONG DEEP LAYER AND LOW LEVEL SHEAR WILL AGAIN SUPPORT
SUPERCELL STORM STRUCTURES WITH ALL MODES OF SEVERE WEATHER
POSSIBLE. A PERIOD OF VERY HEAVY RAINFALL WILL ALSO LIKELY OCCUR
MONDAY NIGHT WITH SOME FLOODING BECOMING POSSIBLE.

MODELS SUGGEST THE MID LEVEL TROUGH WILL TRANSLATE ACROSS THE SRN
PLAINS ON TUESDAY WITH ITS ATTENDANT COLD FRONT FINALLY PROGRESSING
EWRD. HIGH CHANCES FOR THUNDERSTORMS CONTINUES TUESDAY...ESPECIALLY
SOUTH AND EAST WITH SEVERE POTENTIAL CONTINUING.

ANOTHER TROUGH DEVELOPS INTO THE WRN CONUS MID WEEK RESULTING IN
ZONAL FLOW BEHIND THE FIRST SYSTEM TO BECOME MORE SOUTHWESTERLY
AGAIN. HEIGHTS BUILD SLOWLY OVER THE PLAINS AND LEE SFC TROUGH
STRENGTHENS ALLOWING MOIST AND UNSTABLE AIR TO RETURN BACK TO THE
REGION BY THURSDAY. LOW POPS AND NEAR CLIMO TEMPS WERE FORECAST
WITH THIS EXPECTED PATTERN THU-SAT.

915 PM CDT SAT MAY 18 2013

...SIGNIFICANT SEVERE WEATHER EXPECTED SUNDAY AND MONDAY...

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

.DAY ONE...TONIGHT.

SEVERE THUNDERSTORM.
	RISK...LIMITED.
	AREA...ALONG AND WEST OF HIGHWAY 75.
	ONSET...AFTER 10 PM.

DISCUSSION...

SEVERE THUNDERSTORMS OVER CENTRAL OKLAHOMA WILL GRADUALLY SPREAD
EAST INTO EAST CENTRAL AND NORTHEAST OKLAHOMA TONIGHT. THE STORMS
HAVE A HISTORY OF PRODUCING SEVERE WIND GUSTS...BOTH ON THE LEADING
EDGE OF THE GUST FRONT...AND ON THEIR NORTHERN FRINGE WHERE HEAT
BURSTS HAVE BEEN OBSERVED. THUS...DAMAGING WINDS WILL BE THE MAIN
HAZARD WITH THE STORMS TONIGHT IF THEY ARE TO HOLD TOGETHER. THE
AREA MOST LIKELY TO BE AFFECTED WILL BE MAINLY ALONG AND WEST OF
HIGHWAY 75. SOME LARGE HAIL POTENTIAL WILL EXIST FOR A SHORT TIME AS
WELL IF NEW STORMS INITIATE ON THE SURGING OUTFLOW. STORMS SHOULD
DISSIPATE AS THEY TRAVEL FARTHER EAST INTO THE STRONGER CAP.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
LOCAL SPOTTER ACTIVATION MAY BE NEEDED.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.
SUNDAY...SEVERE THUNDERSTORM POTENTIAL...HIGH WIND POTENTIAL.
MONDAY...SEVERE THUNDERSTORM POTENTIAL...HEAVY RAIN POTENTIAL.
TUESDAY...THUNDERSTORM POTENTIAL.
WEDNESDAY...NO HAZARDS.
THURSDAY AND FRIDAY...THUNDERSTORM POTENTIAL.

EXTENDED DISCUSSION...

SIGNIFICANT SEVERE WEATHER IS EXPECTED BOTH SUNDAY AND MONDAY.
CONDITIONS CONTINUE TO LOOK SUPPORTIVE OF TORNADOES...SOME STRONG TO
EVEN VIOLENT...EXTREMELY LARGE HAIL...AND DAMAGING WINDS BOTH SUNDAY
EVENING AND OVERNIGHT AND AGAIN MONDAY AFTERNOON AND EVENING.

NORTHEAST OKLAHOMA APPEARS MOST LIKELY TO BE IMPACTED BY THE
STRONGEST STORMS ON SUNDAY AFTERNOON...EVENTUALLY SPREADING EAST
INTO NORTHWEST ARKANSAS SUNDAY NIGHT. THE AREA WITH THE GREATEST
SEVERE POTENTIAL ON MONDAY DEPENDS LARGELY ON EFFECTS FROM
STORMS SUNDAY NIGHT. IF A LARGE STORM CLUSTER CAN ORGANIZE SUNDAY
NIGHT...AN OUTFLOW BOUNDARY WILL BE LAID OUT ON MONDAY ACROSS THE
REGION. STORMS THAT FORM NEAR THIS BOUNDARY MONDAY AFTERNOON
WOULD HAVE ELEVATED TORNADO POTENTIAL...AGAIN SOME OF THESE COULD
BE STRONG OR EVEN VIOLENT. THE FAVORED ZONE FOR SIGNIFICANT SEVERE
WEATHER ON MONDAY WILL CONTINUE TO BE REFINED IN LATER OUTLOOKS.
REGARDLESS...MUCH OF EASTERN OKLAHOMA AND NORTHWEST ARKANSAS WILL
BE UNDER THE GUN FOR ANOTHER ACTIVE SEVERE WEATHER DAY ON MONDAY.

A SLOW MOVING COLD FRONT WILL AGAIN SERVE AS A FOCUS FOR SEVERE
STORMS ON TUESDAY...HOWEVER CONDITIONS APPEAR SLIGHTLY LESS FAVORED
FOR SIGNIFICANT SEVERE WEATHER.  THE PATTERN ALOFT WILL CONTINUE
TO BECOME LESS CONDUCIVE FOR SEVERE WEATHER BY LATE WEEK.

THE REPEATED ROUNDS OF THUNDERSTORMS...ALONG WITH POTENTIAL FOR
SLOW MOVING STORMS...WILL RAISE THE FLOODING POTENTIAL WITH TIME.
THIS WILL BE ESPECIALLY PRESENT ON MONDAY AND TUESDAY.

AFTER A BRIEF BREAK FROM THE STORMS ON WEDNESDAY...SOME CHANCE FOR
THUNDERSTORMS WILL EXIST AGAIN FOR THE LATTER PART OF THE WEEK
ALONG THE RETREATING FRONTAL BOUNDARY. WINDS ALOFT WILL BE WEAKER
BY THIS TIME...THUS SEVERE WEATHER POTENTIAL WILL BE MUCH LESS
COMPARED THE NEXT COUPLE OF DAYS.

EMERGENCY MANAGEMENT PLANNING STATEMENT...

AN ACTIVE SEVERE WEATHER PERIOD IS EXPECTED WITH NUMEROUS
WATCHES AND WARNINGS BOTH SUNDAY AND MONDAY.  ADDITIONALLY...
GIVEN THE POTENTIAL FOR SIGNIFICANT SEVERE WEATHER...ANY
DAMAGE RESPONSE SHOULD BE CLOSELY COORDINATED GIVEN CONTINUED
SIGNIFICANT SEVERE WEATHER POTENTIAL ON MONDAY. SOME SEVERE
POTENTIAL EVEN EXISTS ON TUESDAY AS WELL.
