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 Blacksburg, VA wrote its last area forecast discussion before this severe thunderstorm warning went out at May 2, 4:14 PM EDT, 3 hours 32 minutes earlier.

Area forecast discussion, May 2, 4:14 PM EDT, 3 hours 32 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
414 PM EDT WED MAY 2 2012

.SYNOPSIS...

A FRONTAL BOUNDARY DRAPED EAST TO WEST ACROSS OUR AREA THIS
EVENING WILL PROVIDE THE FOCUS FOR SPOTTY SHOWER AND THUNDERSTORM
ACTIVITY...MAINLY ACROSS THE MOUNTAINS. EXPECT AN UPPER LEVEL
DISTURBANCE TO LIFT NORTH FROM THE GULF COAST ON THURSDAY...AND
TRIGGER WIDELY SCATTERED THUNDERSTORMS ACROSS THE MOUNTAINS DURING
THE LATE AFTERNOON AND THE EVENING.

&&

.NEAR TERM /THROUGH THURSDAY/...
AS OF 300 PM EDT WEDNESDAY...

RADAR INDICATES SPOTTY SHOWER AND THUNDERSTORM ACTIVITY THIS
AFTERNOON...DEVELOPING MAINLY SOUTH OF A BOUNDARY STRETCHING FROM
TAZEWELL COUNTY TO CHARLOTTE COUNTY IN VIRGINIA. THUNDERSTORM
ACTIVITY HAS BEEN WEAK FOR THE MOST PART...BUT DID NOTICE ONE OR
TWO STRONG THUNDERSTORM ACROSS THE NORTH CAROLINA MOUNTAINS
EARLIER. WITH MAXIMUM AFTERNOON HEATING OCCURRING...WILL HAVE TO
KEEP A CLOSE EYE ON THE RADAR AS AN UPPER LEVEL DISTURBANCE
APPROACHES THE AREA FROM WEST VIRGINIA OVER THE NEXT FEW HOURS. AS
SUCH...STORM PREDICTION CENTER HAS ISSUED AN OUTLOOK FOR CENTRAL
VIRGINIA...STATING THE POSSIBILITY OF A SEVERE THUNDERSTORM WATCH
FOR PORTIONS OF THE FORECAST REGION. EXPECT A FEW STORMS TO BECOME
SEVERE THIS EVENING...WITH LARGE HAIL AND STRONG WINDS. SHOWER AND
THUNDERSTORM ACTIVITY WILL FIZZLE GRADUALLY AFTER SUNSET...AND
EXPECT ALL CONVECTION TO BE GONE SHORTLY AFTER MIDNIGHT.

THE OVERNIGHT HOURS ARE EXPECTED TO REMAIN QUIET...WITH PATCHY
LIGHT FOG DEVELOPING ACROSS THE AREA. FOG WILL LIKELY BE THICKER
IN AREAS WHICH RECEIVE A HEAVY RAIN THIS EVENING. OTHERWISE...
SOUTHERLY FLOW WILL KEEP SUMMERLIKE CONDITIONS ESTABLISHED ACROSS
OUR AREA OVERNIGHT...AND WILL BE LOOKING FOR LOW TEMPERATURES IN
THE UPPER 50S AND THE LOW 60S.

THE MAIN CONCERN FOR THURSDAY WILL BE THE REDEVELOPMENT OF
THUNDERSTORM ACTIVITY DURING THE AFTERNOON AND EVENING. A STRONG
UPPER LEVEL DISTURBANCE WILL MOVE NORTH FROM THE GULF COAST
TONIGHT...AND WILL PUSH NORTHEAST THROUGH TENNESSEE...KENTUCKY
AND WEST VIRGINIA DURING THE EVENING. BELIEVE THIS DISTURBANCE
WILL TRIGGER SCATTERED STRONG TO SEVERE THUNDERSTORMS ACROSS THE
MOUNTAINS...WITH LARGE HAIL AND DAMAGING WINDS AS THE PRIMARY
CONCERNS. HEAVY RAIN WILL ALSO BE A CONCERN...BUT STORMS SHOULD
MOVE FAST ENOUGH SO AS NOT TO SIT OVER ANY ONE PLACE FOR AN
EXTENDED PERIOD OF TIME. TEMPERATURES WILL REMAIN VERY SUMMERLIKE
ON THURSDAY THANKS TO CONTINUED DEEP SOUTHERLY FLOW...AND WE CAN
EXPECT HIGHS REACHING INTO THE MID 80S OVER THE MOUNTAINS..AND
INTO THE LOW 90S ACROSS THE PIEDMONT.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/...
AS OF 200 PM EDT WEDNESDAY...

THE MEDIUM RANGE MODELS ARE IN GOOD AGREEMENT LIFTING AND WEAKENING
THE UPPER LEVEL SHORT WAVE CURRENTLY ACROSS THE GULF COAST STATES.
AS THIS SYSTEM MOVES THROUGH LATE THURSDAY INTO EARLY FRIDAY...GOOD
UPPER LEVEL DIVERGENCE COMBINED WITH LINGERING INSTABILITY AND LOW
LEVEL THETA-E RIDGE SHOULD PRODUCE A FAIRLY ORGANIZED AREA OF STORMS
IN THE WESTERN PORTION OF THE FORECAST AREA...SO INCREASED POPS
THURSDAY NIGHT.

DEW POINTS REMAINING IN THE 60S WILL KEEP OVERNIGHT LOWS MUGGY...AND
SOME LOCATIONS WILL HAVE THE POTENTIAL TO BREAK RECORD HIGH MINIMUMS
(SEE CLIMATE SECTION BELOW).

FRIDAY'S FORECAST IS A CHALLENGING ONE...AND WHILE TEMPERATURES HAVE
THE POTENTIAL TO BE VERY WARM...KEPT READINGS A DEGREE OR TWO BELOW
GUIDANCE WITH THE POSSIBILITY OF WIDESPREAD CLOUD COVER FROM MORNING
STORMS. STILL...ENOUGH INSTABILITY REMAINS AND ANOTHER WAVE MOVING
THROUGH THE NORTHERN PERIPHERY OF THE RIDGE WILL BRING ANOTHER ROUND
OF SCATTERED STORMS.

A SIMILAR PATTERN WILL BE IN PLACE SATURDAY...BUT WITH THE GFS NOT
INDICATING ANY SIGNIFICANT UPPER WAVES MOVING THROUGH THE NW
FLOW...COVERAGE OF SHOWERS AND STORMS SHOULD BE LESS.

&&

.LONG TERM /SUNDAY THROUGH TUESDAY/...
AS OF 200 PM EDT WEDNESDAY...

THE RNK FORECAST AREA WILL RESIDE ON THE NORTHERN PERIPHERY OF AN
UPPER LEVEL RIDGE FOR MUCH OF THE LONG TERM PERIOD. THE 00Z ECMWF IS
MUCH MORE AGGRESSIVE IN WEAKENING THE UPPER RIDGE NEXT WEEK...BUT
THE ITS ENSEMBLE MEAN SUGGESTS THE AMPLITUDE OF APPROACHING
UPPER LEVEL TROF MID-WEEK WILL BE MUCH WEAKER...PLACING OUR AREA IN
MORE OF A ZONAL FLOW.

A FAIRLY MOIST LOW LEVEL ENVIRONMENT COMBINED WITH WEAK UPPER LEVEL
WAVES MOVING THROUGH THE NORTHERN PERIPHERY OF THE RIDGE...WILL KEEP
A CHANCE OF THUNDERSTORMS FOR THE AREA EACH DAY.

AFTER A WEAK BACKDOOR COLD FRONT MOVES THROUGH OUR AREA LATE
SATURDAY NIGHT/EARLY SUNDAY...TEMPERATURES SHOULD BE SLIGHTLY
COOLER...BUT STILL ABOVE NORMAL...UNLESS A COMPLEX OF STORMS BRINGS
WIDESPREAD CLOUD COVER OVER THE REGION.

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

ALL STATIONS ARE REPORTING VFR CONDITIONS THIS AFTERNOON...WITH
MOST OF THE REGION REPORTING A SCATTERED TO BROKEN CU FIELD. RADAR
ALSO INDICATES A FEW SHOWERS AND ISOLATED THUNDERSTORMS ACROSS THE
REGION...HOWEVER NONE OF THIS ACTIVITY IS ORGANIZED.

SHOWER AND THUNDERSTORM COVERAGE IS EXPECTED TO INCREASE ACROSS
THE AREA BY LATE AFTERNOON AND EARLY EVENING AS AFTERNOON HEATING
HELPS DESTABILIZE THE ATMOSPHERE. A FEW THUNDERSTORMS WILL BECOME
SEVERE...WITH LARGE HAIL...DAMAGING WINDS AND HEAVY RAIN. HEAVY
RAIN WITH THESE STORMS MAY ALSO TEMPORARILY LOWER VISIBILITIES TO
LESS THAN A MILE. THUNDERSTORM COVERAGE WILL GRADUALLY DIMINISH
AFTER SUNSET WITH THE LOSS OF DAYTIME HEATING.

SOUTHERLY FLOW WILL REMAIN ESTABLISHED OVERNIGHT...AND WITH LIGHT
WINDS AND SCATTERED CLOUDS...MAINLY CIRRUS BLOWOFF LEFT OVER FROM
EARLIER CONVECTION...WILL EXPECT PATCHY FOG TO DEVELOP ACROSS THE
AREA. VISIBILITIES ARE EXPECTED TO FALL INTO THE 3SM TO 5SM RANGE
FOR MOST AIRPORTS SHORTLY BEFORE SUNRISE...HOWEVER VISIBILITIES
MAY FALL AS LOW AS 1SM AT LOCATIONS WHERE HEAVY RAINFALL OCCURS
THIS EVENING. VISIBILITIES WILL IMPROVE QUICKLY BEGINNING AROUND
9AM.

SHOWERS AND THUNDERSTORMS ARE EXPECTED TO REDEVELOP THURSDAY.
WHILE CONVECTION WILL BE POSSIBLE ANYWHERE ACROSS THE REGION
BEGINNING DURING LATE MORNING...THUNDERSTORM ACTIVITY IS EXPECTED
TO INCREASE IN BOTH COVERAGE AND INTENSITY DURING THE LATE
AFTERNOON AND EVENING ACROSS THE MOUNTAINS AS AN UPPER LEVEL
DISTURBANCE LIFTS NORTHEAST FROM TENNESSEE THROUGH WEST VIRGINIA.
BLF...LYH...AND BCB CAN EXPECT THE GREATEST THUNDERSTORM COVERAGE...
HOWEVER WILL NOT RULE OUT THUNDERSTORMS AT ROA...DAN...LYH. A FEW
OF THESE THUNDERSTORMS WILL AGAIN BE SEVERE...WITH LARGE HAIL AND
DAMAGING WINDS.

SUB-VFR CONDITIONS FOR CEILINGS MAY RETURN LATE IN THE WEEKEND AS HIGH
PRESSURE BUILDS SOUTH ALONG THE LEE OF THE APPALACHIANS AFTER THE
PASSAGE OF A BACKDOOR COLD FRONT.
