Severe Thunderstorm Warning 112, NWS Greenville-Spartanburg, SC

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
318 PM EDT TUE JUN 12 2007

.SYNOPSIS...
AN UPPER LEVEL LOW WILL CROSS THE REGION TONIGHT AND BRING
COOLER...BUT NEAR NORMAL AIR TO THE REGION. HIGH PRESSURE WILL RIDGE
DOWN THE EASTERN SEABOARD THROUGH THE REMAINDER OF THE WORK WEEK AND
MAINTAIN A DRIER AND COOLER AIRMASS ACROSS THE CAROLINAS AND
NORTHEAST GEORGIA.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
CONVECTION FIRED A LITTLE LATER THAN EXPECTED THIS AFTERNOON...BUT
HAS QUICKLY BECOME SEVERE IN SEVERAL LOCATIONS. SEVERE THUNDERSTORM
WATCH ALREADY OUT FOR ALL THE CWFA. DEWPOINTS DID MIX OUT A LITTLE
BUT LAPS DATA SHOWING MODERATE INSTABILITY ACROSS MAJORITY OF CWFA.
AS OF 18Z...DCAPE VALUES RANGED FROM 1100 J/KG SOUTHWEST TO 800 J/KG
NORTHEAST. BEST SHEAR OVER SOUTHWESTERN NC INTO NE GA AND WRN
UPSTATE. EXPECT ANY ORGANIZED MULTICELLS TO DEVELOP THERE...BUT
SEVERE WILL BE POSSIBLE AT ANY LOCATION GIVEN THE INSTABILITY...LOW
FREEZING LEVELS AND HIGH DCAPE VALUES. WILL GO LIKELY POP MOST
LOCATIONS INTO THE EARLY EVENING. ALTHOUGH THREAT OF WIDESPREAD
FLOODING IS LOW...STORMS ARE MOVING CYCLONICALLY AND SEEM TO
CURRENTLY BE PIVOTING AROUND THE CLT METRO AREA. WILL HAVE TO WATCH
CLOSELY FOR ANY FLASH FLOODING.

CONVECTION SHOULD QUICKLY END AFTER SUNSET AS THE SHORT WAVE/COLD
POOL MOVES SOUTH OF THE AREA. PATCHY DENSE FOG POSSIBLE
OVERNIGHT...ESPECIALLY LOCATIONS WHERE DECENT RAIN OCCURS. MODELS
INSIST THAT SOME DRYING WILL STILL OCCUR OVERNIGHT...BUT MAGNITUDE IS
LESS THAN PREVIOUS FORECAST. IF DRYING LAGS...THEN WIDESPREAD FOG
MAY OCCUR ONCE AGAIN.

WEDNESDAY...WEAKER SHORT WAVES AND DEEPER MOISTURE ROTATE INTO THE
AREA. THIS COMBINED WITH EASTERLY FLOW WILL LEAD TO LIKELY POPS OVER
THE EASTERN CWFA AND CHC WEST. WENT HIGHER POP THAN MOS FOLLOWING
THE SREF TRENDS IN TIMING AND VALUES. TEMPS WILL BE COOLER GIVEN
MORE CLOUDS FROM THE DEEPER MOISTURE. ATMOS WILL BE UNSTABLE ENOUGH
FOR THUNDER...BUT MID LEVEL TEMPS WILL BE SLIGHTLY WARMER. EXPECT
ANY SEVERE STORMS TO BE ISOLATED.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY/...
UNSETTLED WEATHER WILL BE THE RULE THROUGH THE SHORT RANGE AS LARGE
UPPER LOW REMAINS ANCHORED OFF THE COAST OF SOUTHERN NEW ENGLAND
WITH LOBES OF VORTICITY ROTATING SOUTH ACROSS THE FORECAST AREA. IN
THE LOWER LEVELS...A MOIST GENERALLY EASTERN FLOW WILL PERSIST.
COMBINING ALL OF THAT WITH UPSLOPE FORCING...PRECIPITATION CHANCES
WILL BE RATHER HIGH WED NIGHT THROUGH FRI. HAVE SHOWED SOMEWHAT OF A
DIURNAL TREND IN THE POPS WITH HIGHER NUMBERS/COVERGAGE DURING THE
AFTERNOON WHEN THE BETTER INSTABILITITY EXISTS. HOWEVER...UPSLOPE
FLOW WIL CONTINUE THREAT OF SHOWERS IN FOOTHILLS AND MOUNTAINS
EVEN AT NIGHT. GENERAL MAV POPS AGAIN TOO LOW...SO TRENDED POPS
TOWEARD THE HIGHER MOS THUNDERSTORM NUMBERS. MAXIMUM TEMPERATURES
WIL BE BELOW SEASONAL LEVELS THROUGH FRIDAY WITH LOW HEIGHTS AND
CONSIDERABLE CLOUD COVER. MOS BLEND LOOKS REASONABLE FOR
TEMPERATURES.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
A PATTERN CHANGE IS ADVERTISED IN THE EXTENDED RANGE AS THE HIGH
AMPLITUDE OMEGA TYPE BLOCK BREAKS DOWN DUE TO ENERGY MOVING THROUGH
NORTHERN US AND SOUTHERN CANADA. THIS ENERGE BREAKS DOWN PERSISTENT
UPPER HIGH THROUGH THE EASTERN CENTRAL US AND KICKS EAST COAST
TROUGH EAST. THIS RESULTS IN A NW FLOW PATTERN EARLY IN THE PERIOD
IN THE SE WITH AN UPPER RIDGE EVENTUALLY BUILDING ALONG THE EAST
COAST. SHORT WAVE AND ASSOCIATED SURFACE COLD APPROACHES LATE IN THE
PERIOD.

HPC GUIDANCE GENERALLY FOLLOWED THIS SCENARIO WITH TEMPERATURES
WARMING TO ABOVE SEASONAL AVERAGES OVER THE WEEKEND. PRECIPITATION
CHANCES APPEAR LOW THROUGH MONDAY WITH ONLY ISOLATED AFTERNOON
MOUNTAIN CONVECTION. POPS INCREASE INTO THE CHANCE RANGE ALL
AREAS TUESDAY AFTERNOON WITH APPROACHING SHORT WAVE.

&&

.AVIATION /19Z TUESDAY THROUGH SUNDAY/...
NUMEROUS SHOWERS AND THUNDERSTORMS WILL MOVE ACROSS THE AREA THROUGH
EARLY EVENING. VCTS INCLUDED AT ALL SITES AND HAVE ALREADY AMENDED
WHERE CELLS THREATENING AIRFIELDS. WILL CONTINUE TO AMEND AS
NECESSARY GIVEN CELL MOVEMENT...BUT TS MAY WELL BE NEEDED AT ALL
SITES BEFORE THE EVENING IS OVER. ANY RESTRICTIONS THROUGH THE
EVENING WILL BE DIRECTLY ASSOCIATED WITH STORMS. WINDS GENERALLY
EAST BUT WILL BE VARIABLE AND GUSTY NEAR STORMS. EXPECT FOG IN
SEVERAL LOCATIONS OVERNIGHT. RIGHT NOW...ONLY HAVE IFR AT KAVL...BUT
CANNOT RULE IT OUT ANYWHERE RAIN FALLS. FAIRLY DEEP MOISTURE MOVES
INTO THE AREA WED. DO NOT EXPECT ANY RESTRICTIONS AFTER THE MORNING
FOG ATTM. SHOWERS AND THUNDERSTORMS WILL DEVELOP DURING THE
AFTERNOON ONCE AGAIN...BUT HAVE LEFT OUT OF THE TAFS FOR NOW.

AVIATION OUTLOOK...SURFACE HIGH PRESSURE CENTERED TO THE NORTH WILL
CONTINUE A LIGHT EASTERLY WIND FLOW THAT WILL ADVECT ENOUGH MOISTURE
INTO THE AREA TO FUEL SCATTERED AFTERNOON AND EVENING THUNDERSTORMS
THROUGH SATURDAY. RELATIVELY COLD TEMPERATURES ALOFT ASSOCIATED WITH
AN UPPER LEVEL TROUGH WILL CONTRIBUTE TO UNSTABLE LAPSE RATES WITH
ATTENDANT STRONG AFTERNOON THUNDERSTORMS. LOW LEVEL MOISTURE LIKELY
TO CAUSE LOWERED LATE NIGHT AND EARLY MORNING CEILINGS AND
VISIBILITIES IN STRATUS AND FOG.

NC...NONE.
SC...NONE.
