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 Blacksburg, VA wrote its last area forecast discussion before this severe thunderstorm warning went out at May 5, 3:40 PM EDT, 33 minutes earlier.

Area forecast discussion, May 5, 3:40 PM EDT, 33 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
340 PM EDT MON MAY 5 2014

.SYNOPSIS...

A FRONTAL BOUNDARY WILL STALL ACROSS OUR REGION THROUGH WEDNESDAY.
AN UPPER RIDGE WILL BUILD OVER THE REGION THURSDAY...RESULTING IN
WARMER...DRIER CONDITIONS. HIGH PRESSURE WILL GIVE WAY TO A SLOW
MOVING FRONTAL SYSTEM LATE FRIDAY.

&&

.NEAR TERM /THROUGH TUESDAY/...

AS OF 330 PM EDT MONDAY...

FRONTAL BOUNDARY WITH A FEW WAVES OF LOW PRESSURE ALONG IT AND
BAROCLINIC ZONE WILL REMAIN ACROSS OUR REGION THIS AFTERNOON INTO
TUESDAY. BECAUSE THE BOUNDARY IS PARALLEL TO THE UPPER FLOW THERE
WILL BE LITTLE CHANCE IN THE FRONTAL POSITION. FOR THIS AFTERNOON
INTO TONIGHT...THERE REMAIN THE POTENTIAL FOR ISOLATED STRONG TO
SEVERE THUNDERSTORMS WITH THE MAIN THREAT OF WIND AND HAIL AS
HIGHLIGHTED IN THE SWODY1 SEE TEXT MENTION. MLCAPE VALUES AROUND 500
J/KG AND STEEP LOW-LEVEL LAPSE RATES COULD PROMOTE MIXING OF
STRONGER FLOW ALOFT...AND HELP WITH DAMAGING WINDS THREAT.

THE LOCAL RNK WRFARW AND HRRR CAPTURE THE PLACEMENT OF THE
CONVECTION THE BEST THIS AFTERNOON WITH STORMS MOVING SOUTHEAST
TONIGHT. THE NAM AND RAP13 LOOKED OVERDONE WITH COVERAGE IN
NEW RIVER VALLEY AT THIS TIME THEN SHIFT FOCUS ACROSS THE NORTH.
THE ECMWF AND GFS LOOKED SIMILAR FOR TONIGHT WITH CONVECTION. IN
GENERAL...THE BEST PROBABILITY OF PRECIPITATION WILL OCCUR ACROSS
THE NORTHERN PART OF THE COUNTY WARNING AREA. LESS COVERAGE ACROSS
THE SOUTH WHERE CAP IS THE STRONGEST. WENT WITH LOW TEMPERATURES
CLOSE TO THE ADJMAVBC WITH READINGS FROM THE MID 40S ACROSS THE
NORTH TO THE MID 50S ALONG THE SOUTHERN BLUE RIDGE MOUNTAINS.

NAM AND ECMWF HAVE DECREASE COVERAGE OF STORMS ON TUESDAY WHILE THE
GFS PLACES MORE ACTIVITY OVER OUR REGION. PLACEMENT OF UPPER RIDGE
MAY SUPPRESS THUNDERSTORM DEVELOPMENT ESPECIALLY IN THE SOUTH.
WHILE A SHORTWAVE IN THE UPPER FLOW MAY TRIGGER ISOLATED CELLS IN
THE NORTH. HIGH TEMPERATURES TUESDAY WILL RANGE FROM THE MID 60S
IN THE NORTHWEST MOUNTAINS TO THE LOWER 80S ALONG THE FOOTHILLS OF
THE SOUTHERN BLUE RIDGE.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/...
AS OF 338 PM EDT MONDAY...

FRONTAL BOUNDARY SOUTH OF US TUESDAY EVENING WILL CONTINUE TO BE
INFLUENCING THE WEATHER THRU WEDNESDAY. ENOUGH CONVERGENCE TO CARRY
AT LEAST SLIGHT CHANCE POPS ACROSS THE FOOTHILLS AND PIEDMONT
TUESDAY EVENING. OVERNIGHT...MODELS ESPECIALLY THE 12Z ECMWF/GFS
TRACK A VORT TIED TO DYING MCS ACROSS OUR NRN CWA...SO UPPED POPS TO
30ISH THERE...LINGERING THRU WED MORNING. THINK CLOUD COVER WILL BE
LIMITING FACTOR ON WEDNESDAY WEATHER PLUS WE START TO SEE UPPER
RIDGE BUILDING. HIGH PRESSURE EAST OF US TO HOLD ONTO CLOUDINESS IN
THE NORTH AND EAST WHILE SUNSHINE RETURNS TO THE SOUTH. ENOUGH OF A
CAP WITH MAIN FORCING TO THE NORTH TO KEEP LITTLE TO NO CHANCE OF
WEDNESDAY AFTERNOON.

TEMPS WEDNESDAY TRICKY GIVEN DYING MCS IN THE MORNING AND LINGERING
CLOUDINESS COMBINED WITH HEIGHTS INCREASING AND LIMITED WEDGE WITH
HIGH TO THE EAST. WENT TOWARD COOLER ECWMF MOS WITH WARMEST TEMPS
STAYING OVER THE SW CWA WITH BLF/JFZ REACHING 80...WHILE THE LOWER
TO MID 70S OCCUR FROM THE NRV AND BLUE RIDGE NORTH AND EAST.

SHOULD BE DRY WED NIGHT-THU NIGHT...WITH UPPER RIDGE OVER THE
SOUTHEAST. HIGHS THURSDAY WILL BE ON TRACK TO REACH THE 80S OVER A
GOOD DEAL OF THE REGION...MAYBE APPROACH/REACH 90 ACROSS THE
SOUTHSIDE VA PIEDMONT AND NW NC PIEDMONT.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
AS OF 200 PM EDT MONDAY

VARIABILITY IN THE MODELS LEADS TO A LOW
CONFIDENCE FORECAST. THEREFORE...WENT WITH PERSISTENCE BLENDED WITH
WPC AND 00Z ECMWF FOR THIS FORECAST. STILL LOOKING AT A SW FLOW
ALOFT WITH HEIGHTS GRADUALLY FALLING TOWARD THE WEEKEND AS THE UPPER
TROUGH SLIDES EAST INTO THE OHIO VALLEY AND WEST OF THE SMOKYS. THE
PATTERN FAVORS INCREASING HUMIDITY WITH THE DAILY THREAT OF SHOWERS
AND STORMS. THE FRONTAL BOUNDARY OVER THE REGION MIDWEEK WILL BE
NORTH OF US FRIDAY WITH SFC HIGH SITUATED OVER THE SOUTHEAST COAST.
A COLD FRONT EDGES INTO THE CENTRAL APPALACHIANS AND MID MISS VALLEY
BY SATURDAY.

THE UPPER FLOW STAYS PROGRESSIVE WITH THIS FRONT WEAKENING OVER THE
EAST WITH NEXT UPSTREAM SYSTEM MOVING INTO THE MS VALLEY BY LATER IN
THE WEEKEND. THIS NEXT FRONT EXPECTED TO SLIDE EAST ACROSS THE
EASTERN OHIO VALLEY MONDAY.

BASED ON THIS...FORECAST REFLECTS HIGHER POPS FRI NIGHT-SAT
NIGHT...AND AGAIN MONDAY WITH LOWER POPS IN BETWEEN. AGAIN...THE
THREAT OF SHOWERS AND STORMS REMAINS ALL FRI-MON...BUT SOME DAYS
COULD BE WETTER THAN OTHERS...SO NOT A COMPLETE WASHOUT EITHER.

TEMPS WILL BE ABOVE NORMAL.

&&

.AVIATION /20Z MONDAY THROUGH SATURDAY/...
AS OF 215 PM EDT MONDAY...

FRONTAL BOUNDARY WILL REMAIN NEARLY STATIONARY ACROSS THE REGION
DURING THE TAF PERIOD. WINDS TONIGHT MAY SHIFT DIRECTION
PERIODICALLY AS THE FRONT WAVERS BACK AND FORTH ACROSS THE REGION.

UNSTABLE AIR WILL DEVELOP SOUTH OF THE FRONT BY THIS AFTERNOON.
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS WILL LINE UP ALONG
THE FRONT FROM ILLINOIS INTO VIRGINIA. BUFKIT SOUNDINGS SHOWED A
CAP AT KDAN AND KLYH WHICH MAY SUPPRESS THE GROWTH OF SHOWERS AND
THUNDERSTORMS TODAY BUT HAVE KEPT A BETTER CHANCE IN THE
KBCB/KLWB/KBLF AND KROA TAFS THIS AFTERNOON INTO TONIGHT.
CONVECTION IS LINING UP NICELY WITH LATEST RUN OF RNK WRFARW.
THE GFS LOOKS OVERDONE WITH CONVECTION FOR THE NEW RIVER
VALLEY...WITH STRONG CAP IN PLACE THIS AFTERNOON. THE NAM AND
ECMWF HAD GOOD COVERAGE ACROSS THE NORTHERN HALF OF FORECAST AREA
THIS AFTERNOON AND LIFT IT NORTH TONIGHT. MVFR CEILINGS AND
VISIBILITIES ARE LIKELY WITH THE THUNDERSTORMS. COVERAGE OF
SHOWERS AND THUNDERSTORMS WILL DIMINISH AROUND SUNSET.

TUESDAY INTO WEDNESDAY...THE FRONT WILL REMAIN STALLED OVER THE
FORECAST AREA RESULTING IN A PERSISTENT CHANCE OF SHOWERS AND
THUNDERSTORMS...ESPECIALLY DURING THE AFTERNOON AND EVENING. MVFR
CONDITIONED SHOULD BE EXPECTED WITH ANY OF THE SHOWERS AND
STORMS.

MEDIUM CONFIDENCE IN VISIBILITY...CEILINGS AND WINDS DURING THE
TAF PERIOD.

THURSDAY THE FRONT LIFTS NORTH WITH DRIER WEATHER AND WARMER AIR
MOVING INTO THE REGION. BY LATE FRIDAY A COLD FRONT WILL APPROACH
FROM THE WEST...BRINGING A CHANCE OF SHOWERS AND THUNDERSTORMS TO
THE MOUNTAINS.
