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 Jun 25, 8:34 PM EDT, 36 minutes earlier.

Area forecast discussion, Jun 25, 8:34 PM EDT, 36 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RALEIGH NC
834 PM EDT MON JUN 25 2012

.SYNOPSIS...
AN UPPER LEVEL TROUGH DIGGING SOUTHEAST FROM THE GREAT LAKES INTO
THE MID-ATLANTIC WILL DRIVE A COLD FRONT SOUTHWARD INTO CENTRAL
NORTH CAROLINA LATE THIS AFTERNOON AND EVENING. DRY CONDITIONS ARE
EXPECTED TO PREVAIL THE REMAINDER OF THE WEEK AS A STRENGTHENING
UPPER LEVEL RIDGE BUILDS INTO THE AREA FROM THE WEST...BRINGING
ABOVE NORMAL TEMPERATURES BY THE END OF THE WEEK.

&&

.NEAR TERM /THROUGH TUESDAY/...
AS OF 230 PM MONDAY...

OVERVIEW:
AN AMPLIFYING NORTHERN STREAM SHORTWAVE TROUGH AND ASSOCIATED
SURFACE COLD FRONT WILL SURGE SOUTH...REACHING THE VIRGINIA
TIDEWATER REGION THIS AFTERNOON AND MOVING THROUGH CENTRAL NORTH
CAROLINA LATER THIS EVENING. NOTICEABLY DRIER AND COOLER AIR WILL
FILTER INTO THE CAROLINAS ON TUESDAY AS CANADIAN HIGH PRESSURE
OVER THE UPPER MIDWEST/GREAT LAKES REGIONS BUILDS SOUTHEAST INTO
THE REGION.

REMAINDER OF THE AFTERNOON AND EVENING:
DEEP LAYER SCALE ASCENT ACCOMPANYING THE DIGGING SHORT WAVE TROUGH
AND ASSOCIATED COLD FRONT WILL SURGE SOUTHEAST DOWN ACROSS THE
MID ATLANTIC SEABOARD...WITH THE CORE OF STRONG SYNOPTIC HEIGHT
FALLS ON THE ORDER OF 60 TO 90 METER HEIGHT FALLS MOVING OFF THE
DELMARVA COAST THIS EVENING. NORTHERN PORTIONS OF CENTRAL NORTH
CAROLINA WILL BE ON THE SOUTHERN PERIPHERY OF THIS IMPRESSIVE
SHORTWAVE TROUGH DYNAMICS...ESPECIALLY BETWEEN 21 TO 03Z WITH DEEP
LAYER SHEAR INCREASING TO AROUND 35 TO 40 KNOTS DURING THAT
TIME... ENHANCED BY THE RIGHT ENTRANCE REGION JET UNDERCUTTING THE
DIGGING WAVE.

BEFORE THE ARRIVAL OF THE UPPER TROUGH/COLD FRONT FORCING... MODERATE
TO STRONG DESTABILIZATION WILL SUPPORT ISOLATED TO SCATTERED
CONVECTION... FOCUSED IN THE VICINITY OF OF THE PREFRONTAL TROUGH AND/OR
DIFFERENTIAL HEATING BOUNDARY THAT HAS SETUP ACROSS CENTRAL NORTH
CAROLINA WHERE THE COMBINED EFFECTS OF SLOW STRATUS BURN OFF FROM
EARLIER THIS MORNING AND BROKEN CIRRUS CANOPY ASSOCIATED WITH THE
OUTER CIRRUS BAND HAS RESULTED IN UNEQUAL HEATING. BUT STILL
EXPECT THE MAIN SEVERE THREAT TO ACCOMPANY THE LEADING EDGE OF THE
SOUTHWARD DROPPING FRONTAL ZONE AND INCREASING SHEAR FROM THE
NORTH. GIVEN INCREASING SHEAR...EXPECT ANY CONVECTION THAT
DEVELOPS WILL BE ORGANIZED...WITH ROTATING UPDRAFTS CERTAINLY
POSSIBLE. IN FACT...THE ENVIRONMENT APPEARS TO BE SUPPORTIVE OF
LEFT/RIGHT SPLITTING SUPERCELLS (EQUALLY FAVORED) GIVEN
UNIDIRECTIONAL SHEAR IN NORTHWEST FLOW ALOFT. SHEAR PROFILES SHOW
THE MAJORITY OF SPEED SHEAR IN THE MID LEVELS (10 TO 20 THOUSAND
FEET AGL)...WITH NO MORE THAN 10 TO 15 KNOT FLOW BELOW TEN
THOUSAND FEET AGL AND LITTLE IF ANY CLOCKWISE HODOGRAPH
CURVATURE. SO...IN THE ABSENCE OF ANY MESOSCALE OR CONVECTIVE
INTERACTIONS THAT ACT TO ENHANCE LOW LEVEL SHEAR...THE SEVERE
THREAT WILL BE CONFINED TO DAMAGING WINDS AND LARGE HAIL. EXPECT
THE THREAT FOR SEVERE WEATHER TO BE GREATEST BETWEEN 3 PM AND 11
PM WITH POPS TAPERING OFF FROM NORTH TO SOUTH BY 06Z AS FRONT
PUSHES SOUTH OF THE FORECAST AREA.

TONIGHT:
MINIMUM TEMPERATURES TONIGHT WILL BE DEPENDENT ON THE TIMING OF
THE COLD FRONTAL PASSAGE AND DRIVEN BY COLD AIR ADVECTION. AT
THIS TIME EXPECT THE COLD FRONT TO CROSS THE VIRGINIA/NORTH
CAROLINA BORDER SHORTLY AFTER 00Z...AND THE NORTH CAROLINA/SOUTH
CAROLINA BORDER BY OR SHORTLY AFTER 06Z. LOW LEVEL THICKNESSES ARE
FORECAST TO PLUMMET TO AROUND 1365 METERS AT KGSO BY 12Z/26
TUESDAY... APPROXIMATELY 40 METERS BELOW CLIMATOLOGICAL VALUES FOR
THIS TIME OF YEAR. COOLEST ACROSS THE NORTH WHERE COOLER AIR WILL
BE FIRST TO ARRIVE. MINIMUM TEMPERATURES RANGING FROM THE UPPER
50S NEAR THE VIRGINIA BORDER TO THE MID 60S SOUTH.

TUESDAY:
BUILDING CONTINENTAL POLAR AIR MASS WILL MAKE ABSOLUTELY DELIGHTFUL
CONDITIONS FOR LATE JUNE...WITH BOUNDARY LAYER DEWPOINTS INTO THE
MID 40S RESULTING IN COMFORTABLE RELATIVE HUMIDITY LEVELS. LOW
LEVEL THICKNESSES ARE PROJECTED TO BE AROUND 20 METERS BELOW
NORMAL...SUPPORTING DAYTIME HIGHS IN THE 79 TO 83.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/...
AS OF 1230 PM MONDAY...

LATEST FORECAST TRACK FOR TROPICAL STORM DEBBY TAKES THE STORM
ACROSS THE UPPER FLORIDA PENINSULA IN THE THURSDAY TIME FRAME. THE
STORM WILL REMAIN TOO FAR SOUTH TO INFLUENCE THE SHORT TERM FORECAST.

UPPER TROUGH MIGRATES OFFSHORE WITH WARM CORE RIDGING BUILDING IN
FROM THE MIDWEST. STRONG CAPPING ALOFT WILL SUPPRESS CONVECTION
AND TEMPERATURES WILL BE ON THE UPSWING...FROM NEAR NORMAL MID TO
UPPER 80S ON WEDNESDAY TO THE LOW...PERHAPS MID 90S ON THURSDAY.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
AS OF 1230 PM MONDAY...

THE TRACK OF TROPICAL STORM DEBBY REMAINS IN QUESTION AND A TRACK
NEARER THE ATLANTIC COAST COULD PERHAPS PRODUCE SOME IMPACTS IN FAR
EASTERN NORTH CAROLINA IN THE LATE WEEKEND. OTHERWISE...THE MID
LEVEL RIDGE BUILDING IN FROM THE WEST FLATTENS ACROSS THE
SOUTHERN CONUS INTO THE WEEKEND. THE RESULTING CAPPED ATMOSPHERE
WITH HOT AIR MASS IN PLACE AND COPIOUS SUN WILL ALLOW TEMPERATURES
TO APPROACH RECORD TRIPLE DIGITS ON FRIDAY AND SATURDAY.

RETROGRESSION WESTWARD OF THE RIDGE LATE THIS WEEKEND WOULD TAKE THE
EDGE OFF THE HIGHS IN NORTHWEST FLOW...BUT STILL LOOKS LIKE MOSTLY
MID 90S SUNDAY AND MONDAY. LOSS OF THE CAP WOULD ALSO PERMIT WIDELY
SCATTERED DIURNAL CONVECTION. WITH NO SIGNIFICANT FORCING MECHANISMS
DETECTABLE AT THIS POINT...WILL KEEP POPS IN THE SLIGHT CHANCE
RANGE.

&&

.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
AS OF 830 PM MONDAY...

24-HR TAF PERIOD:

A FRONT DROPPING SOUTH FROM THE VIRGINIA BORDER WITH WIDELY
SCATTERED SHOWERS AND THUNDERSTORMS ALONG AND TO ITS SOUTH. THE
RISK FOR CONVECTION WILL BE SLOWEST TO CLEAR THE SOUTHEAST...
WHERE ISOLATED STORMS MAY BE POSSIBLE UNTIL ABOUT 4 AM. WINDS
BRIEFLY GUSTY TO 20 MPH NEAR AND BEHIND THE WIND SHIFT. VFR
TUESDAY UNDER A NORTH TO NORTHEAST WIND LESS THAN 10 MPH.

VFR CONDITIONS WITH CLEAR SKIES AND VERY LITTLE CHANCE FOR
PRECIPITATION THROUGH SATURDAY AS A STRENGTHENING UPPER LEVEL
RIDGE BUILDS INTO THE AREA FROM THE WEST.
