Severe Thunderstorm Warning 85, NWS Raleigh, NC

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE RALEIGH NC
217 PM EDT SUN JUN 20 2010

.SYNOPSIS...
AN UPPER LEVEL RIDGE WILL EXPAND EASTWARD ACROSS OUR REGION THROUGH
MUCH OF THE WEEK...BRINGING AN EARLY SEASON HEAT WAVE TO THE AREA.

&&

.NEAR TERM /THROUGH MONDAY/...
AS OF 215 PM SUNDAY...

SFC ANALYSIS THIS AFTERNOON SHOWED A WEAK TROUGH EXTENDING SOUTH
FROM NEW ENGLAND THROUGH THE MID-ATLANTIC INTO CENTRAL/EASTERN NC.
ALOFT...12Z RAOB ANALYSIS AND WV IMAGERY/RUC DATA SHOWED AN H5 RIDGE
CENTERED IN EASTERN TX...WITH A RIDGE AXIS EXTENDING EASTWARD
THROUGH THE DEEP SOUTH/TN VALLEY. CENTRAL NC IS ON THE NORTHEAST
PERIPHERY OF THE H5 RIDGE. AN WEAKENING MCV REMNANT WAS NOTED
DIRECTLY OVER THE CAROLINAS...ROUGHLY FROM CAE-RDU-AKQ...SHOWING UP
WELL IN RUC H5 VORTICITY. A WEAK BAROCLINIC WAVE AT H25 WAS NOTED
JUST UPSTREAM ON THE WESTERN SIDE OF THE SOUTHERN APPALACHIANS.

REST OF TODAY:
THE WEAK SFC-925 MB TROUGH CURRENTLY IN THE COASTAL PLAIN WILL STALL
OUT IN EASTERN NC THIS AFT/EVE IN ASSOC/W A VERY WEAK FLOW REGIME ON
THE NORTHEAST PERIPHERY OF THE UPPER LEVEL RIDGE CENTERED IN TX.
ALOFT...THE WEAKENING MCV CURRENTLY EXTENDING FROM CAE-RDU-AKQ IS
PROGGED TO MEANDER ESE TOWARD GREENVILLE BY 21Z AND MHX BY 00Z.
LOOKING AT THE RUC DYNAMIC TROPOPAUSE...THE WEAK BAROCLINIC WAVE
CURRENTLY NOTED JUST WEST OF THE MOUNTAINS MAY MEANDER INTO WESTERN
NC AND GA/UPSTATE SC BY 00Z. PWAT VALUES OFF THE 12Z RAOBS RANGE
FROM 1.75" AT MHX...TO ~1.50" AT GSO...TO 0.80" AT RNK. LIGHT N/NW
FLOW IN THE MID-LEVELS ON THE NORTHEAST PERIPHERY OF THE H7 RIDGE
(CENTERED IN THE LOWER MS RIVER VALLEY) SHOULD HELP TO ADVECT LOWER
PWAT VALUES INTO THE WEST/NW PIEDMONT THIS AFTERNOON...FALLING INTO
THE 1.00-1.25" RANGE. FURTHER EAST...PWAT VALUES SHOULD REMAIN AOA
1.50"...PRIMARILY FROM THE TRIANGLE EAST/SOUTH.

FORCING TODAY WILL BE ASSOC/W WEAK LOW LEVEL CONVERGENCE ALONG THE
SFC-925 MB TROUGH AXIS IN THE COASTAL PLAIN AND WITH WEAK DPVA
ASSOC/W THE REMNANT MCV MEANDERING ESE INTO EASTERN NC THIS AFT.
LATEST 18Z OBJECTIVE ANALYSIS FROM THE SPC MESOANALYSIS PAGE SHOWS
1000-2000 J/KG OF MLCAPE ACROSS THE LOWER...LOWEST NW AND HIGHEST
SE. EXPECT DEWPOINTS TO FALL INTO THE MID 60S (PERHAPS LOWER) IN THE
WESTERN PIEDMONT/TRIANGLE THIS AFT ON THE WESTERN SIDE OF THE
SFC-925 MB TROUGH...HOWEVER...DEWPOINTS MAY REMAIN AOA 70F
SOUTH/EAST OF THE TRIANGLE. WITH ALL THIS IN MIND...FEEL THAT THERE
SHOULD BE ENOUGH FORCING/INSTABILITY PRESENT FOR A SLIGHT CHANCE
(20%) OF SHOWERS/STORMS TO BE INTRODUCED EAST OF I-95 THROUGH MID
AFTERNOON...ALTHOUGH THE RELATIVE BEST CHANCE WILL PROBABLY BE
OUTSIDE OF THE RAH CWA IN EASTERN NC WHERE THE SFC-925 MB TROUGH IS
MORE APT TO STALL OUT...AND WHERE THE SLOW MOVING REMNANT MCV WILL
BE JUXTAPOSED WITH PEAK HEATING. EXPECT CHANCES FOR CONVECTION EAST
OF I-95 TO WANE BY ~21Z GIVE OR TAKE AN HOUR...AND WILL REMOVE
PRECIP CHANCES BY SUNSET. FURTHER WEST IN THE TRIANGLE AND NW
PIEDMONT...WEAK SUBSIDENCE IN THE WAKE OF THE MCV...FALLING PWAT
VALUES (DRYING MID-LEVELS) AND WEAKER INSTABILITY IN ASSOC/W LOWER
DEWPOINTS SHOULD HELP KEEP A LID ON CONVECTION...SIMILAR TO
YESTERDAY WHERE A FEW ISOLD SHOWERS TRIED TO DEVELOP BUT QUICKLY
DIED VIA DRY-AIR ENTRAINMENT. ALTHOUGH EFFECTIVE BULK SHEAR VALUES
ARE < 15 KNOTS...GIVEN STEEP LOW-LEVEL LAPSE RATES AND DCAPE VALUES
1000-1500 J/KG...SHOULD ANY DEEP CONVECTION DEVELOP...THERE WOULD BE
AN ASSOC THREAT OF DAMAGING WINDS. HIGHS TODAY ARE EXPECTED TO
EASILY MAKE IT INTO THE LOWER/MID 90S...OR 91-95F. HEAT INDICES WILL
MAKE IT CLOSE TO ~100F IN THE SOUTHEAST COASTAL PLAIN WHERE
DEWPOINTS WILL REMAIN THE HIGHEST.

TONIGHT:
PWAT VALUES ARE EXPECTED TO CONTINUE TO FALL FROM THE NORTHWEST
OVERNIGHT...DOWN TO ~1.35" EVEN AT FAY/RWI. ALTHOUGH WE SHOULD SEE
SOME FORCING FROM THE WEAKENING H25 BAROCLINIC WAVE PROGGED TO PUSH
EAST ACROSS THE CAROLINAS...EXPECT THIS TO FALL SHORT OF ENOUGH
FORCING FOR CONVECTION...PARTICULARLY GIVEN DRY MID/UPPER LEVELS AND
VERY WEAK THERMODYNAMICS. AS A RESULT...WILL KEEP THE FCST DRY
TONIGHT...WITH LOWS IN THE LOWER 70S...OR 71-74F.

MONDAY:
THE UPPER LEVEL RIDGE CENTERED TO OUR WEST/SW WILL STRENGTHEN A BIT
AND EXTEND FURTHER EAST/NE INTO THE CAROLINAS ON MON. WITH WARMER
MID-LEVELS...AND DEWPOINTS EXPECTED TO MIX OUT INTO THE 60S IN MOST
LOCATIONS...EXPECT A MORE HOSTILE THERMODYNAMIC ENVIRONMENT FOR
CONVECTION DURING PEAK HEATING MON. ADDITIONALLY...DO NOT ANTICIPATE
ANY SIGNIFICANT FORCING MECHANISMS FOR CONVECTION...EITHER AT THE
SURFACE OR ALOFT. ALTHOUGH A ROGUE SHOWER/STORM CANNOT BE RULED OUT
IN SAMPSON/CUMBERLAND/WAYNE COUNTIES IN ASSOC/W THE SEABREEZE AND
PERHAPS 1000-1500 J/KG MLCAPE DOWN THAT WAY...PROBABILITIES LOOK TOO
LOW TO MENTION. AS A RESULT...WILL KEEP THE FORECAST DRY.
THICKNESSES FOR MON LOOK VERY SIMILAR TO TODAY...AND WILL FCST
SIMILAR HIGHS...ALBEIT SLIGHTLY WARMER TO ACCOUNT FOR AIRMASS
MODIFICATION...92-96F...COOLEST NW PIEDMONT. -VINCENT

.SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/...
AS OF 215 PM SUNDAY...

THE EARLY SUMMER HEAT WAVE WILL BE WELL UNDERWAY THIS PERIOD WITH
NO SIGNS OF IT BREAKING THROUGH THE WEEK. MODELS AGREE ON THE
CURRENT MASSIVE UPPER RIDGE EXPANDING EASTWARD FROM THE SOUTHERN
PLAINS THROUGH THE SOUTHEASTERN AND MID-ATLANTIC STATES TUESDAY
INTO WEDNESDAY. UPPER HEIGHTS MAX OUT AT 5930M OVER NC BOTH
DAYS. THE CORE OF THE UPPER RIDGE IS EXPECTED TO MAX OUT AT 5960M
OVER THE SOUTHERN PLAINS THIS SAME PERIOD. THE MID LEVEL CORE IS
FORECAST OVER THE TN VALLEY AND SOUTHERN APPALACHIANS TUE-WED.
THIS ASSURES TEMPS WILL SOAR AS SUBSIDENCE WILL PREDOMINATE WITH
NEARLY FULL SUNSHINE BEFORE THE CONVECTIVE TEMPS ARE MET AROUND
MID AFTERNOON. THE ONLY POP WILL BE TO CARRY A 20 (SLIGHT CHANCE)
OF A THUNDERSTORM AT ANY ONE GIVEN LOCATION BOTH DAYS. THIS IS
10-15 PERCENT BELOW THE 30 YEAR DAILY CLIMATOLOGY FOR A
THUNDERSTORM FOR LATE JUNE. A SUBTLE AND WEAK WAVE IN THE NW FLOW
ALOFT COULD BE JUST ENOUGH WHEN COMBINED WITH THE STRONG HEATING
AND THE WEAK PIEDMONT SURFACE TROUGH TO KICK OFF A FEW STORMS EACH
DAY... BUT WIDESPREAD CONVECTION IS NOT EXPECTED. GIVEN THE AMOUNT
OF MLCAPE FORECAST (2000-2500 J/KG)... ANY STORM THAT DEVELOPS
WILL POTENTIALLY BE A PULSE SEVERE STORM.

HOWEVER...THE MAIN WEATHER PROBLEMS WILL BE THE MAXIMUM TEMPERATURES
AND THE HEAT INDICES (HEAT AND HUMIDITY). MODELS ARE IN GOOD GENERAL
AGREEMENT WITH THE TEMPERATURES WITH SOME SUBTLE DIFFERENCES. WE
CURRENTLY FAVOR THE SLIGHTLY LOWER NUMBERS FROM THE MET GUIDANCE
WITH THE EXCEPTION OF A FEW OF THE TYPICAL HOT SPOTS (KRDU FOR
EXAMPLE)... ESPECIALLY AS THE SURFACE WINDS ARE FORECAST TO BECOME
SW AND REMAIN SW BOTH DAYS. WE WILL FORECAST MID TO UPPER 90S EXCEPT
92-94 IN THE NW PIEDMONT BOTH DAYS. LOWS SHOULD REMAIN 70+ WITH SOME
MID 70S ESPECIALLY BY WED AM.

IT IS THE DEW POINT AND HEAT INDEX FORECASTS THAT BECOME MORE
PROBLEMATIC AS EARLY AS TUESDAY. KEEP IN MIND THAT 105 DEGREE HEAT
INDICES FOR 3 HOURS TIME IS THE THRESHOLD FOR HEAT ADVISORY
CRITERIA. BEGINNING TUESDAY AFTERNOON... THE NAM FORECAST DEW
POINTS TO BE HIGHER THAN THE GFS. THIS IS IMPORTANT OVER THE
EASTERN ZONES AS THE NAM IS QUICKER TO FORECAST HEAT INDICES OF
105 ALONG AND SE OF A LINE EXTENDING FROM ROCKINGHAM TO RALEIGH TO
ROANOKE RAPIDS. IT APPEARS THAT THERE MAY BE JUST ENOUGH MIXING
ON TUESDAY TO ALLOW THE SURFACE DEW POINTS TO FALL JUST BELOW 70
FOR MANY AREAS... WHICH FAVORS THE SLIGHTLY DRIER GFS MOS. THIS
WOULD ALLOW THE HEAT INDICES TO REMAIN 100-104 INSTEAD OF 105 OR
HIGHER AS SUGGESTED BY THE NAM MOS. THIS WILL HAVE TO BE WATCHED
CLOSELY.

A HEAT ADVISORY WILL LIKELY BE NEEDED FOR THE EASTERN ZONES
INCLUDING THE TRIANGLE AREA BY WEDNESDAY AFTERNOON. TEMPS OF 95-98
COMBINED WITH DEW POINTS AROUND 72 WOULD YIELD 105+ FOR HEAT INDEX
VALUES.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
AS OF 215 PM SUNDAY...

HEAT WAVE CONDITIONS EXPECTED AT LEAST THU-FRI AS THE MID/UPPER
RIDGE IS FORECAST TO REMAIN STRONG FROM THE SOUTHERN PLAINS
EASTWARD TO THE SE COAST. THE MAIN MID LEVEL CORE SHOULD SHIFT
BACK WESTWARD FROM THE TN VALLEY LATER IN THE WEEK... POTENTIALLY
ALLOWING HEIGHTS TO LOWER A BIT OVER VA/NC FRI-SAT. THIS MAY ALLOW
A WEAK SURFACE FRONT OR TWO TO NEAR THE REGION INCREASING THE
CHANCE OF PM CONVECTION. WE WILL TREND IN THAT DIRECTION BUT
SLOWER THAN THE GFS SUGGESTS. THIS ONLY BRINGS A SUBTLE TEMP DROP
(A FEW DEGREES). THIS COMES WITH A PRICE AS DEW POINTS WILL BE
HIGHER (70+). THE CHANCE OF PULSE SEVERE WILL INCREASE ALONG WITH
HIGH HEAT INDICES EACH DAY.

&&

.AVIATION /18Z SUNDAY THROUGH THURSDAY/...
AS OF 215 PM SUNDAY...

24-HR TAF PERIOD:
VFR CONDITIONS ARE EXPECTED THROUGH THE TAF PERIOD...WITH LIGHT
NORTHWEST WINDS AT MOST TAF SITES. CANNOT RULE OUT AN ISOLD
SHRA/TSRA AT FAY/RWI IN THE 18-00Z TIME FRAME...ALTHOUGH PROBS ARE
TOO LOW TO INCLUDE MENTION. PRE-DAWN MVFR FOG WILL ALSO REMAIN
POSSIBLE...PRIMARILY AT THE FAY/RWI TAF SITES IN THE 07-12Z TIME
FRAME.

18Z MONDAY THROUGH THURSDAY:
A DEEP UPPER LEVEL RIDGE EXTENDING INTO THE AREA FROM THE WEST WILL
LEAD TO GENERALLY HOT/DRY CONDITIONS THROUGH MID-WEEK. CANNOT
ENTIRELY RULE OUT A FEW ISOLD SHRA/TSRA DURING PEAK HEATING...ALONG
WITH A CHANCE FOR MVFR FOG DURING THE PRE-DAWN HOURS...PRIMARILY AT
THE FAY/RWI TAF SITES. -VINCENT
