What was reported inside it

Time	Report	Where	Remark
Mar 30, 11:40 AM CDT	FLOOD	2 W Honobia, OK	STREET FLOODING IN AND AROUND COMMUNITY OF HONOBIA
Mar 30, 11:40 AM CDT	FLOOD	Poteau, OK	SEVERAL SIDE STREETS CLOSED DUE TO HIGH WATER

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 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, 2.4 hours before the alert went out and 248 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 Mar 30, 3:29 AM CDT, 5 hours 52 minutes earlier.

Area forecast discussion, Mar 30, 3:29 AM CDT, 5 hours 52 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
329 AM CDT SUN MAR 30 2008

.DISCUSSION...
WIDESPREAD CONVECTION DEVELOPED THIS MORNING WITHIN BROAD LOW LEVEL
JET AXIS...AND THIS FORCING REGIME IS LIKELY TO REMAIN IN PLACE
THROUGH THE MORNING HOURS WITH A GRADUAL DECREASE IN COVERAGE FROM
WEST TO EAST. ISOLATED SEVERE WEATHER IS POSSIBLE DURING THIS
TIMEFRAME. SURFACE WARM FRONT CURRENTLY ACROSS NORTHEAST TEXAS
WILL WEAKEN WHILE LIFTING NORTHWARD TODAY...WITH THE SYNOPTIC WARM
SECTOR ENVELOPING THE FORECAST AREA BY THIS EVENING. LOW CLOUDS
WILL LIMIT WARMING HOWEVER HIGH TEMPERATURES NEARER NORMAL ARE
EXPECTED. THE COLD FRONT CURRENTLY DROPPING THROUGH THE HIGH
PLAINS AND A SHARPENING DRYLINE ACROSS WEST TEXAS WILL REMAIN THE
PRIMARY BOUNDARIES TO FOCUS STORMS BY THIS EVENING. THESE
BOUNDARIES ARE EXPECTED TO REMAIN WEST AND NORTH OF THE FORECAST
AREA...HOWEVER ANY LONG TRACK STORMS MAY IMPACT AREAS NORTH OF
INTERSTATE 44 THIS EVENING.

THE LATEST DATA CONTINUES TO SUPPORT VOLATILE WEATHER POTENTIAL FOR
MONDAY AND MONDAY NIGHT ACROSS THE AREA. THE LARGEST UNCERTAINTIES
WILL LIKELY CONTINUE TO CIRCULATE AROUND THE IMPACT OF EARLY DAY
CONVECTION AND LOW CLOUDINESS AND THE RESULTANT IMPACTS ON
AVAILABLE INSTABILITY. WHILE A NOTICEABLE GRADIENT IN SURFACE
BASED INSTABILITY IS POSSIBLE...THE DEGREE OF SYNOPTIC FORCING AND
FAVORABLE SHEAR PROFILES MAY WELL OFFSET THIS IMPACT WITHIN ANY
SUSTAINED STORM UPDRAFT. THIS YIELDS A SCENARIO OF SUSTAINABLE
UPDRAFTS WITHIN STRONG DEEP LAYER SHEAR THAT IS FAVORABLY
ORIENTATED TO SURFACE BOUNDARIES TO MAINTAIN A CELLULAR MODE. THE
POTENTIAL WILL ALSO EXIST FOR STORMS TO INITIATE ALONG THE WESTERN
EDGE OF THE LOW LEVEL JET AXIS...WHICH GIVEN THE LACK OF BACKING
FLOW...WOULD PLACE THE ORIGINATION ZONE EAST OF THE DRYLINE. THE
RESULTANT FORECAST IS SCATTERED SUPERCELLS DEVELOPING BY MID
AFTERNOON...POSSIBLY FURTHER EAST THAN THE DRYLINE...AND PRODUCING
SIGNIFICANT SEVERE WEATHER GIVEN THE WIND PROFILES WITHIN THE BASE
OF THE UPPER TROUGH AXIS. ADDITIONAL SEVERE WEATHER WILL ACCOMPANY
THE FAST MOVING COLD FRONT MONDAY NIGHT...AS A SQUALL LINE
DEVELOPS ALONG THE FRONTAL BOUNDARY AND OVERTAKES ANY PRE-FRONTAL
STORMS. A RESPONSE TO SEVERE WEATHER WATCHES AND WARNINGS SHOULD BE
ANTICIPATED FOR MONDAY.

A BRIEF PERIOD OF QUIET AND DRY WEATHER TUESDAY...WITH INCREASING
STORM CHANCES WEDNESDAY AND ESPECIALLY THURSDAY. GIVEN THE
PERSISTENT MODEL AGREEMENT ON THE NEXT SYSTEM...HAVE INCREASED
PRECIP CHANCES INTO THE LIKELY CATEGORY FOR THURSDAY. FORECAST UNCERTAINTY
INCREASES BY THE WEEKEND AS VARIOUS LONG RANGE MODEL OUTPUT BECOMES
OUT OF PHASE.

SEVERE THUNDERSTORM.
	RISK...LIMITED.
	AREA...EASTERN OKLAHOMA AND WESTERN ARKANSAS.
	ONSET...ONGOING.

DISCUSSION...
REMAINS OF LLJ ASSOCIATED CONVECTION FROM THE OVERNIGHT HOURS WILL
CONTINUE TO PROVIDE AN ISOLATED THREAT FOR HAIL PRODUCING STORMS
THIS MORNING... PARTICULARLY IN SOUTHEASTERN OKLAHOMA AND WESTERN
ARKANSAS.

LATER TODAY... STRONG TO SEVERE STORMS MAINLY ASSOCIATED WITH THE
DRYLINE TO OUR WEST AND THE WARM FRONT TO OUR NORTH MAY WANDER
INTO OUR REGION.

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

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

EXTENDED DISCUSSION...
THE GREATEST THREAT FOR SEVERE WEATHER IN EASTERN OKLAHOMA AND WESTERN
ARKANSAS WILL BE MONDAY AFTERNOON AND EVENING. MUCH WILL DEPEND
UPON THE LIMITING EFFECTS OF ANY CLOUD COVER AND NON-SEVERE
CONVECTION EARLIER IN THE DAY. HOWEVER... A WARM... MOIST... AND
UNSTABLE ENVIRONMENT WILL BE IN PLACE ACROSS THE REGION AS AN
UPPER TROUGH TRAVERSES THE PLAINS. UPPER LEVEL WINDS WILL PROVIDE
GOOD DYNAMICS FOR PRE-FRONTAL SUPERCELLS EARLY IN THE EVENT. IN
ADDITION... A FAST MOVING COLD FRONT WILL BE THE FOCUS FOR LINEAR
TYPE CONVECTION AS IT SURGES THROUGH THE AREA MONDAY EVENING INTO
TUESDAY MORNING.

AFTER A BRIEF PERIOD OF TRANQUIL WEATHER... ANOTHER UPPER SYSTEM
WILL PRODUCE A GOOD CHANCE FOR THUNDERSTORMS ACROSS THE REGION WEDNESDAY
AND PARTICULARLY THURSDAY.

EMERGENCY MANAGEMENT PLANNING STATEMENT...
EMERGENCY MANAGERS SHOULD PREPARE FOR THE LIKELIHOOD OF DAMAGING SEVERE
STORMS MONDAY... AND CONTINUE TO MONITOR THE LATEST FORECASTS AND
INFORMATION CONCERNING THIS POTENTIALLY DANGEROUS WEATHER EVENT.
