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 Raleigh, NC wrote its last area forecast discussion before this severe thunderstorm warning went out at May 24, 3:02 PM EDT, 1 hour 34 minutes earlier.

Area forecast discussion, May 24, 3:02 PM EDT, 1 hour 34 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RALEIGH NC
302 PM EDT TUE MAY 24 2011

.SYNOPSIS...
HIGH PRESSURE CENTERED WELL OFF THE SOUTHEAST COAST WILL CONTINUE TO
EXTEND WESTWARD ACROSS THE SOUTHEAST AND GULF STATES THROUGH FRIDAY.
THE RESULTING FLOW FROM THE SOUTHWEST WILL PUMP UNSEASONABLY WARM
AIR INTO THE AREA THROUGH THE END OF THE WORK WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
AS OF 250 PM TUESDAY...

AREA OF CONVECTION SLIDING EAST ALONG VA BORDER HAS SENT A GUST
FRONT WELL INTO THE PIEDMONT INTO THE NORTHERN COASTAL PLAIN. THIS
FEATURE MAY SERVE AS A FOCUS FOR ADDITIONAL CONVECTIVE DEVELOP LATER
TONIGHT. IN THE MEAN TIME...VORT MAX TRIGGERING THE CONVECTION ALONG
THE BORDER AREA WILL ADVANCE EAST WITH WEAK SUBSIDENCE IN ITS WAKE.
ANOTHER VORT MAX OVER THE TN VALLEY TRIGGERING ANOTHER ROUND OF
CONVECTION BETWEEN NASHVILLE AND LONDON KY. NEAR TERM MODELS ADVANCE
THIS VORT MAX TOWARD NW NC AROUND 00Z...AND INTO SOUTHERN VA AROUND
MIDNIGHT. THIS WEATHER SYSTEM MAY TRIGGER ADDITIONAL SCATTERED
CONVECTION THIS EVENING INTO THE OVERNIGHT HOURS. A FEW OF THE WRF
MODELS (NMM WRF...SPC WRF) INDICATE CONVECTION DEVELOPING AS FAR
SOUTH AS THE SANDHILLS AND SOUTHERN PIEDMONT AFTER 06Z. THUS WILL
START OUT THIS EVENING WITH A SMALL CHANCE POP NW PIEDMONT AND
SLIGHT CHANCE ACROSS TH REMAINDER OF THE PIEDMONT AND COASTAL PLAIN.
AFTER 06Z...WILL INDICATE A SLIGHT CHANCE POP OVER MOST OF THE
REGION. IF CLOUDS DEPART/DIMINISH ENOUGH...MAY SEE AREAS OF FOG
DEVELOP. LOW TEMPS 65-70.

&&

.SHORT TERM /WEDNESDAY AND WEDNESDAY NIGHT/...
AS OF 245 PM TUESDAY...

THE HEAT CONTINUES WEDNESDAY AS MID/UPPER LEVEL RIDGE AMPLIFIES
OVER THE REGION IN RESPONSE TO DEEP UPPER LOW OVER THE CENTRAL U.S.
LOW LEVEL THICKNESSES 1425-1430M (ABOUT 3-5M HIGHER THAN THIS
AFTERNOON) SUGGEST MAX TEMPS IN THE LOW-MID 90S...NEAR OR IN RECORD
MAX TEMP TERRITORY. ANY CONVECTION LATE WEDNESDAY-WEDNESDAY EVENING
WILL BE ISOLATED AND CONFINED TO THE FAR NORTH (DUE TO PROXIMITY OF
MID LEVEL WAVES CROSSING WELL TO OUR N-NW).

EXPECT TRANQUIL WEATHER WEDNESDAY NIGHT THOUGH QUITE WARM AND A
LITTLE HUMID WITH MIN TEMPS IN THE 65-70 DEGREE RANGE.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...
AS OF 230 PM TUESDAY...

MEDIUM AND LONG RANGE MODELS CONTINUE TO AGREE ON A WEAKENING
MID-UPPER TROUGH WHICH WILL APPROACH FROM THE WEST FRIDAY...MOVING
ACROSS THE MID ATLANTIC EARLY SATURDAY. AS IT APPROACHES OUR REGION
LATE THURSDAY THERE WILL BE A SLIGHT CHANCE FOR WIDELY SCATTERED
THUNDERSTORMS MAINLY IN THE WEST...BUT SLIGHTLY BETTER CHANCES
SHOULD COME FRIDAY. STRONG SURFACE HEATING COMBINED WITH THE WEAK
SHORTWAVE SHOULD HELP TO ORGANIZE A FEW THUNDERSTORMS IN THE FRIDAY
AFTERNOON WITH THE BEST CHANCES FROM HIGHWAY 1 WEST AS WELL AS ALONG
THE VA BORDER CLOSER TO THE BETTER DYNAMICS. DEPENDING ON THE TIMING
OF THE BEST LIFT RESULTING FROM THE SHORTWAVE...SOME OF THE
THUNDERSTORMS ACTIVITY COULD PERSIST INTO FRIDAY EVENING FROM
RALEIGH NORTH AND EAST. OVERALL POPS WILL RANGE OR AROUND 30 PERCENT
IN THE TRIAD AND ALONG THE VA BORDER TO 20-25 PERCENT IN THE
TRIANGLE AND A 20 PERCENT CHANCE AROUND FAYETTEVILLE DUE TO MAINLY
HEATING. HIGHS WILL BE WARM BOTH DAYS IN THE UPPER 80S TO MID 90S
THURSDAY...THEN BACKING OFF A FEW DEGREES DUE TO A LITTLE MORE CLOUD
COVER WITH MID 80S NW TO AROUND 92 SE FRIDAY. LOWS 65-70.

LESS CONVECTION IS EXPECTED SATURDAY AS THE WEAK WAVE DEPARTS AND AN
UPPER RIDGE SLOWLY BUILDS IN FROM THE SW. UPSLOPE FLOW AND HEATING
MAY SUPPORT A FEW STORMS IN THE FOOTHILLS AND IN THE MOUNTAINS...BUT
THESE SHOULD REMAIN MAINLY WEST OF THE CWA. WILL LOWER POPS TO A
SMALL SLIGHT CHANCE DUE TO DIURNAL AND THE CHANCE OF AN UNORGANIZED
STORM OR TWO. HIGHS IN THE 85-90 RANGE EXPECTED.

INCREASING UPPER RIDGING SUNDAY AND MONDAY SHOULD WILL BRING EVEN
WARMER TEMPERATURES TO THE END OF THE HOLIDAY WEEKEND AND LESS IN
THE WAY OF DIURNAL CONVECTION CHANCES. HIGHS WILL RETURN TO THE
90-95 RANGE (UPPER 80S NW).

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
AS OF 145 PM TUESDAY...

SCATTERED CONVECTION...SOME OF WHICH MAY BE SEVERE WITH WIND GUSTS
50-60KTS AND LARGE HAIL...WILL DEVELOP AND SCOOT EASTWARD ACROSS
THE NORTHERN PIEDMONT INTO THE NORTHERN AND CENTRAL COASTAL PLAIN
THIS AFTERNOON AND EARLY EVENING. MAJORITY OF THE CONVECTION WILL
REMAIN NORTH-NORTHEAST OF THE TRIAD TERMINALS...BUT MAY COME WITHIN
THE VICINITY OF KRDU AND KRWI. ANOTHER BATCH OF CONVECTION MAY
THREATEN THE NORTHERN PIEDMONT AFTER SUNSET...ASSOCIATED WITH A VORT
MAX CURRENTLY CROSSING MID TN.

CONVECTION WILL WANE ACROSS THE NORTHERN PIEDMONT AND COASTAL PLAIN
AFTER 12 MIDNIGHT. AS CLOUDS DISSIPATE...PATCHES OF FOG WILL DEVELOP
WITH POCKETS OF MVFR FOG PROBABLE AT KRDU...KFAY AND IFR/LIFR FOG AT
KRWI.

WEDNESDAY INTO WEDNESDAY NIGHT...EXPECT A PROLONGED PERIOD OF VFR
CONDITIONS. THE CONVECTIVE THREAT DOES NOT APPEAR TO BE AS GREAT AS
THIS AFTERNOON THOUGH AN ISOLATED STRONG THUNDERSTORM CANNOT BE
RULED OUT.

VFR CONDITIONS EXPECTED ACROSS CENTRAL NC THURSDAY THROUGH SUNDAY AS
HIGH PRESSURE NEAR THE SURFACE AND ALOFT IS THE MAIN INFLUENCE ON
OUR WEATHER. DUE TO THE MOIST AIR NEAR THE SURFACE...AREAS OF
MVFR/IFR FOG AND STRATUS WILL OCCUR EACH MORNING.
