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 Raleigh, NC wrote its last area forecast discussion before this flash flood warning went out at Apr 30, 3:20 PM EDT, 4 minutes earlier.

Area forecast discussion, Apr 30, 3:20 PM EDT, 4 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RALEIGH NC
320 PM EDT WED APR 30 2014

.SYNOPSIS... A LARGE AND VIGOROUS STORM SYSTEM OVER THE MIDWEST WILL
CONTINUE TO BRING UNSETTLED WEATHER TO OUR REGION INTO TONIGHT. A
COLD FRONT WILL MOVE SLOWLY EASTWARD ACROSS THE REGION LATE THURSDAY
INTO THURSDAY NIGHT. DRY AND COOLER WEATHER WILL SPREAD IN FROM THE
WEST FRIDAY AND SATURDAY.

&&

.NEAR TERM /THROUGH THURSDAY NIGHT/...
AS OF 320 PM WEDNESDAY...

ONGOING CONVECTION OVER THE COASTAL PLAIN IS MAINLY A FLOODING
THREAT AT THIS POINT WITH VERY FEW DISCRETE ELEMENTS LEFT.  EXPECT
THIS AREA TO MOVE MOSTLY OUT OF THE CWA BY 21Z.
MEANWHILE...ATTENTION SHIFTS BACK TO THE WEST WHERE CAPE HAS BEEN
UNTAPPED SO FAR TODAY.  DEEP LAYER SHEAR WILL INCREASE TO 45-50KT
THROUGH THIS EVENING.  WHILE SURFACE WINDS ARE FORECAST TO SLOWLY
VEER WITH TIME...THEY DO REMAIN SLIGHTLY BACKED...AND THE DEEP LAYER
SHEAR IS SUPPORTIVE OF SUPERCELL STRUCTURE WHICH MAINTAINS THE
THREAT OF LARGE HAIL AND ISOLATED TORNADOES IN ADDITION TO DAMAGING
WINDS AND HEAVY RAIN.   THIS BIGGEST QUESTION HAS BEEN WHAT WILL
TRIGGER STORMS.  THERE IS A WAKE LOW THAT HAS BEEN MOVING UP FROM GS
AND THROUGH UPSTATE SC TODAY...WHICH IS NOW SOMEWHAT EVIDENT IN OBS
OVER THE SOUTHWEST PIEDMONT.  THIS MAY HELP TRIGGER CONVECTION OVER
THE NEXT FEW HOURS. WHILE MANY AREAS OVER THE WESTERN PIEDMONT HAVE
RECEIVED LESS THAN ONE HALF INCH OF RAIN....THE ADDITIONAL STORMS
THIS AFTERNOON MAY STILL CAUSE LOCALIZED FLASH FLOODING.

TONIGHT... STABILIZATION AFTER SUNSET SHOULD CUT DOWN ON CONVECTIVE
COVERAGE...BUT THE SHEAR AXIS CURRENT WEST OF THE MOUNTAINS IS
FORECAST TO PUSH ACROSS THE AREA OVERNIGHT AND WILL LIKELY CONTINUE
AT LEAST SCATTERED SHOWERS AND MAYBE A FEW ISOLATED STORMS. WHERE AS
MODEL HAVE BEEN SHOWING AN ADDITIONAL INCH OR MORE OVERNIGHT...THE
NEWER 12Z MODELS HAVE TRENDED DOWN OVERNIGHT.  WE WILL MAINTAIN AT
LEAST CHANCE POPS OVERNIGHT.  LOWS IN THE 60S.

THURSDAY...
THE UPPER LOW THAT HAS BEEN RESPONSIBLE FOR THE UNSETTLED
WEATHER THIS WEEK WILL OPEN UP AND BEGIN LIFTING NORTHEAST. THE MAIN
AXIS OF PW OVER 1.5 INCHES AND HIGHER THETA E OVER THE AREA TODAY IS
FORECAST TO SHIFT EAST OVER THE COASTAL PLAIN WITH AN EFFECTIVE
FRONT.  MODELS STILL SHOW 1000-1500 J/KG MLCAPE POSSIBLE WITH
DEWPOINTS STILL IN THE UPPER 60S AND LOWER 70S.  PROVIDED LINGERING
SHOWERS EARLY IN THE DAY DONT SQUASH HEATING...HIGHS SHOULD REACH
THE UPPER 70S AND LOWER 80S ACROSS THE EAST.  THE MAIN UPPER JET
AXIS WILL BE SHIFTING EAST WITH THE MEAN TROUGH AND WILL STILL
PROVIDE STRONG DEEP LAYER SHEAR TO SUPPORT A SEVERE THREAT OVER THE
COASTAL PLAIN.

&&

.SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/...
AS OF 315 PM WEDNESDAY...

THE SURFACE COLD FRONT IS EXPECTED TO BE WELL SOUTHEAST OF CENTRAL
NC BY FRIDAY MORNING. WE'LL STILL BE UNDER THE INFLUENCE OF FAST MID
LEVEL FLOW FROM THE SW WITH WEAK PERTURBATIONS TRACKING
NORTHEASTWARD OVER NC FRI... SO EXPECT A VEIL OF MID/HIGH CLOUDS TO
OVERSPREAD CENTRAL/ERN NC FROM LATE MORNING THROUGH FOR MUCH OF THE
AFTERNOON. THE GFS DOES GENERATE A SWATH OF LIGHT PRECIP OVER THE
CENTRAL/ERN CWA FRI... HOWEVER THE LOW LEVELS BELOW 700 MB APPEAR
TOO DRY FOR ANYTHING MORE THAN A QUICK SPRINKLE... SO WILL LEAVE OUT
MEASURABLE POPS. AS THE MID LEVEL TROUGH AXIS APPROACHES FROM THE
WEST LATE FRI INTO FRI NIGHT... ANOTHER SHOT OF ENHANCED CLOUD COVER
IS EXPECTED TO SPREAD OVER THE REGION... PARTICULARLY IN THE
SANDHILLS AND COASTAL PLAIN... BUT AGAIN THE LIMITED FORCING FOR
ASCENT AND LIMITED MOISTURE DEPTH WILL INHIBIT PRECIP DEVELOPMENT.
BELOW NORMAL HIGHS AROUND 70 WITH CLOUDS AND BELOW NORMAL
THICKNESSES. LOWS IN THE UPPER 40S TO LOWER 50S. -GIH

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
AS OF 1225 PM TUESDAY...

WE SHOULD SEE LINGERING MID-HIGH CLOUDS ESPECIALLY IN THE ERN CWA
THROUGH MUCH OF SAT... AS A POTENT VORTICITY MAX CROSSES GA AND THE
CAROLINAS... BUT DRY/STABLE LOW LEVELS WILL INHIBIT PRECIP
DEVELOPMENT. OTHERWISE... ONCE THE MID LEVEL TROUGH AXIS FINALLY
SHIFTS TO OUR EAST SAT EVENING... EXPECT DRY AND SEASONABLE WEATHER
FOR SUNDAY. A STRONG MID LEVEL CLOSED LOW WILL TRACK ESE ACROSS THE
ST LAWRENCE VALLEY AND NEW ENGLAND SUNDAY... SETTLING JUST OFF THE
NEW ENGLAND COAST MON BEFORE WOBBLING TO THE EAST OR NE LATE TUE
THROUGH WED. TO OUR WEST... BROAD RIDGING OVER THE SW QUARTER OF THE
CONUS ON SUNDAY WILL SHIFT EASTWARD THROUGH THE CENTRAL STATES...
AMPLIFYING AS IT REACHES THE SOUTHEAST STATES BY WED. THIS WILL
RESULT IN GENERALLY FLAT NORTHWESTERLY MID LEVEL FLOW OVER THE
REGION. A BACKDOOR FRONTAL ZONE ORIENTED WEST-EAST ACROSS VA SUNDAY
IS EXPECTED TO DIP SOUTHWARD ACROSS NE NC MONDAY... THEN HOLD MAINLY
STATIONARY IN A NW-SE FASHION ALONG THE VA/NC BORDER AND NE NC
THROUGH TUE. IN THIS SORT OF A NORTHWEST FLOW PATTERN THERE IS THE
POTENTIAL FOR UPSTREAM CONVECTION OVER THE OH VALLEY TO TRACK
SOUTHEASTWARD ACROSS NC... AND FOR NOW WILL LEAVE IN A SLIGHT CHANCE
OF SHOWERS AND STORMS FOR MON/TUE TO ADDRESS THIS POTENTIAL. AS THE
RIDGE ALOFT APPROACHES FROM THE WEST LATE TUE INTO WED... THIS
BOUNDARY SHOULD BE PUSHED A BIT NORTHEASTWARD... WITH A DRYING
COLUMN AND WARMING LOW LEVELS. TEMPS CLOSE TO SEASONAL NORMALS
(WHICH IS LOW-MID 50S FOR LOWS AND MID-UPPER 70S FOR HIGHS) THROUGH
TUE... THEN ABOVE NORMAL TEMPS (HIGHS IN LOW-MID 80S) WED. -GIH

&&

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
AS OF 200 PM WEDNESDAY...

MOIST AND UNSTABLE AIR MASS COVERS CENTRAL NC WITH SURFACE WINDS
FROM THE SSE OR SOUTH. THIS IS AHEAD OF A COLD FRONT... NOW PUSHING
SLOWLY EASTWARD THROUGH CENTRAL/ERN TN... AND THIS IS EXPECTED TO
CROSS CENTRAL NC LATE THU/THU NIGHT.

NUMEROUS SHOWERS/STORMS WILL CONTINUE TO IMPACT RDU/FAY/RWI THROUGH
THE REST OF THIS AFTERNOON... THROUGH ABOUT 21Z-23Z. INT/GSO SHOULD
STAY MOSTLY DRY BUT WITH PATCHY SHOWERS. BACKGROUND SURFACE WINDS
WILL REMAIN MAINLY FROM THE SOUTH SUSTAINED AT 7-13 KTS... ALTHOUGH
LOCALLY STRONGER WINDS WITH GUSTS OVER 35 KT ARE LIKELY IN AND NEAR
STORMS. MAINLY MVFR CIGS ARE EXPECTED AT ALL SITES THROUGH ABOUT 04Z
TO 06Z... AND MVFR-IFR VSBYS ARE LIKELY IN AND NEAR STORMS FOR THE
NEXT SEVERAL HOURS. AFTER THE 04Z-06Z TIME FRAME... SHOWER/STORM
CHANCES WILL DECREASE... AND LOW CIGS ARE EXPECTED TO FORM WITH IFR
CIGS AND MVFR VSBYS IN FOG ANTICIPATED AREAWIDE LATE TONIGHT. CIGS
EXPECTED TO LIFT TO MVFR AFTER 13Z THU MORNING... AND POSSIBLE TO
VFR AFTER 16Z... WITH WINDS STRENGTHENING FROM THE SSW AT 10-15 KT
GUSTING TO 20-25 KTS.

LOOKING BEYOND 18Z THU: ADDITIONAL SHOWERS AND A FEW STORMS WITH
ENHANCED WIND GUSTS FROM THE SW TO 25-30 KTS ARE POSSIBLE AT RWI/FAY
THU AFTERNOON AHEAD OF THE FRONT. WINDS WILL LIGHTEN AND SHIFT TO BE
FROM THE WSW OR WEST THU NIGHT AFTER FRONTAL PASSAGE THU NIGHT.
OTHERWISE... VFR CONDITIONS EXPECTED TO DOMINATE CENTRAL NC
TERMINALS THROUGH MON. -GIH
