AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
421 PM EDT WED JUL 2 2014
.SYNOPSIS...
THE CENTER OF ARTHUR WILL TRACK NORTH ALONG THE ATLANTIC COAST
THURSDAY AND FRIDAY. THE CIRCULATION AROUND THE PASSING TROPICAL
SYSTEM WILL SWEEP A WEAK COLD FRONT OFF THE CAROLINA COAST BY
THURSDAY MORNING. A CANADIAN AIR MASS WILL SETTLE OVER THE REGION
FOR THE HOLIDAY WEEKEND. CONDITIONS WILL RETURN TO A TYPICAL SUMMER
TIME PATTERN BY THE MIDDLE OF NEXT WEEK.
&&
.NEAR TERM /THROUGH THURSDAY/...
2030 UTC UPDATE...SKY COVER WAS UPDATED FROM VISIBLE SATELLITE
IMAGERY...RESULTING IN FEW CLOUDS. POP WERE ADJUSTED ACCORDINGLY...
WITH LESS COVERAGE EVERYWHERE BUR THE NORTHERN CLOUD RIDGE...WHERE
RADAR SHOWED CONVECTION DEVELOPING.
AS OF 215 PM...IN THE VERY NEAR TERM NOT A WHOLE LOT OF CONSENSUS
AMONG THE MODELS IN REGARD TO THE AMOUNT OF CONVECTION THAT WILL
DEVELOP THIS AFTERNOON INTO THE EVENING. THE NCEP CAMS PLUS THE
NAM/RAP ARE THE MOST AGGRESSIVE WITH CONVECTIVE DEVELOPMENT...WHILE
OUR LOCAL WRFS AND HRRR ONLY HAVE WIDELY SCATTERED TO SCATTERED
COVERAGE AT BEST. WITH SBCAPES EXCEEDING 3000J/KG AND LITTLE CIN
NOTED...WILL LEAN TO THE MORE AGGRESSIVE CONVECTIVE SOLUTIONS. SO
WILL CONTINUE WITH THE IDEA OF SCATTERED TO NUMEROUS COVERAGE OF
THUNDERSTORMS LATE THIS AFTERNOON FROM THE CENTRAL/NORTHERN
MOUNTAINS...SOUTHEASTWARD INTO THE CENTRAL/EASTERN PIEDMONT. WITH
DCAPES >1000J...STORMS THAT DEVELOP WILL HAVE A GOOD CHANCE OF
PRODUCING LARGE HAIL AND DOWNBURSTS. STORMS SHOULD TEND TO PLAY OUT
THIS EVENING WITH LOSS OF HEATING...BUT BOTH THE GFS/NAM ENHANCE
SURFACE CONVERGENCE OVERNIGHT AS A WEAK COLD FRONT DROPS INTO THE
LEE TROUGH. THE MODELS SHOW SOME QPF RESPONSE SO WILL MAINTAIN
CHANCE TYPE POPS TO ACCOUNT FOR THAT.
ON THU...AS TROPICAL STORM ARTHUR MOVES OFF THE SC COAST...IT WILL
AS EXPECTED CAUSE THE COLD FRONT TO REMAIN STATIONARY OVER THE
FORECAST AREA. ALSO...THE UPPER TROUGH AXIS WILL APPROACH AS WELL.
HENCE..WE EXPECT ANOTHER DAY OF SCATTERED TO NUMEROUS COVERAGE OF
THUNDERSTORMS WITH THE BEST COVERAGE DURING THE AFTERNOON OVER
EASTERN AREAS. MAX TEMPS ON THURSDAY WILL NOT BE QUITE AS HOT WITH
THE ARRIVAL THE FRONT. USED A MODEL CONSENSUS TO PRODUCE MOST GRID
FIELDS.
&&
.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/...
AS OF 200 PM WED...UPPER TROF AXIS WILL SHIFT EAST OF THE AREA FRI
PUSHING A COLD FRONT AND THE TROPICAL CYCLONE WELL EAST OF THE AREA.
WEAK UPPER RIDGING BEGINS TO BUILD OVER THE AREA ON SAT. AT THE
SFC...MILD AND DRY HIGH PRESSURE BEGINS TO RIDGE IN FROM THE NORTH
BEHIND THE DEPARTING WX SYSTEMS FRI...WITH THE CENTER OF THE HIGH
SLIDING TO NEAR THE VA/NC COAST BY THE END OF THE DAY SAT. EXPECT
DRY BUT BREEZY CONDITIONS FRI...WITH BREEZES POSSIBLY LINGERING INTO
FRI NITE...AS THE CWFA WILL BE IN THE RELATIVELY TIGHT PRESSURE
GRADIENT BETWEEN THE DEPARTING FRONT AND APPROACHING HIGH. THERE
COULD EVEN BE SOME LINGERING LOW CLOUDS ACROSS THE AREA EARLY FRI AS
LOW LEVEL MOISTURE REMAINS HIGH. ANY LINGERING BREEZES WILL DIMINISH
SAT MORNING AS PRESSURE GRADIENT RELAXES WITH THE EASTWARD MOVEMENT
OF THE SFC HIGH. CANNOT RULE OUT MORNING LOW CLOUDS AGAIN...BUT DRY
FCST WILL CONTINUE. LOWS THU NITE AND HIGHS FRI WILL BE SLIGHTLY
BELOW NORMAL. LOWS FRI NITE AND HIGHS SAT WILL DROP TO AROUND 5
DEGREES BELOW NORMAL WITH MUCH LOWER HUMIDITY LEVELS.
&&
.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
AS OF 210 PM WED...ON SUNDAY AND MONDAY...WEAK SFC HIGH PRESSURE WILL
CONTINUE TO RIDGE WESTWARD ACROSS THE REGION AS A COLD FRONT LINGERS
ACROSS THE OHIO RIVER VALLEY. THE SFC PATTERN WILL SUPPORT WEAK FLOW
OUT OF THE SOUTH BOTH DAYS...POSSIBLE SUPPORTING MIN RH IN THE MID
40S. A BLEND OF PREFERRED GUIDANCE SUPPORTS TEMPS SLIGHTLY BELOW
NORMAL TO NORMAL TEMPERATURES. HIGH TEMPERATURES ARE FORECAST TO
RANGE FROM THE LOW 80S WITHIN THE MTN VALLEYS TO UPPER 80S/NEAR 90
EAST. FORECAST SOUNDINGS INDICATE A SIGNIFICANT INVERSION AROUND
H65. THE INVERSION SHOULD PROVIDE A CAP EAST OF THE MTNS...WEAKEST
OVER THE RIDGES. I WILL INDICATE SCHC POPS ACROSS THE RIDGES DURING
THE HEAT OF THE AFTERNOON EACH DAY.
TUESDAY AND WEDNESDAY...THE BASE OF A MID LEVEL TROF WILL RIPPLE
ACROSS THE MID WEST AND OHIO RIVER VALLEY. MEDIUM RANGE MODELS
INDICATE THAT ONE OR TWO MID LEVEL S/W MAY RIPPLE ACROSS THE SOUTH
APPALACHIAN REGION DURING THE PERIOD. THE COMBINATION OF MID LEVEL
SUPPORT...LITTLE TO NO AFTERNOON CIN...AND SLIGHT GREATER WEST
STEERING FLOW MAY SUPPORT HIGH CHC POPS ACROSS THE RIDGES...WITH MID
AFTERNOON CHC EAST. TEMPERATURES BOTH DAYS SHOULD RANGE VERY CLOSE
TO NORMAL.
&&
.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
AT KCLT...MAIN CONCERN IS THE TIMING AND DURATION OF THUNDERSTORMS
AT THE AIRFIELD. THE ATMOSPHERE IS EXTREMELY UNSTABLE THIS AFTERNOON
WHICH SUPPORTS STRONG TO POSSIBLY SEVERE THUNDERSTORM DEVELOPMENT..
HOWEVER...IT APPEARS THAT THE ONLY TRIGGER WILL BE FROM AN OUTFLOW
BOUNDARY FROM UPSTREAM STORMS OVER THE FOOTHILLS. 12Z NAM AND LATEST
RAP DEVELOP CONVECTION CIRCA 00Z AT CLT. THIS SEEMS REASONABLE AND
WILL HAVE A TEMPO TSRA FROM 23-03Z. SOME -SHRA COULD REMAIN IN THE
VICINITY FOR SEVERAL HOURS AFTER THE STORMS. WILL ALSO BRING MVFR
CIGS OVER AIRFIELD TOWARD SUNRISE AS SURFACE WINDS TURN MORE
EASTERLY.
ELSEWHERE...THUNDERSTORMS ARE EXPECTED TO BE MOST NUMEROUS OVER THE
NC FOOTHILLS...BUT DEVELOP SE INTO UPSTATE SC LATE THIS AFTERNOON
AND EVNEING. HENCE WILL HAVE TEMPO FOR TSRA AT ALL AIRFIELDS EXCEPT
FOR KAND WHERE ONLY VCTS WILL BE CARRIED. STORMS SHOULD END THIS
EVENING BUT SCATTERED SHRA MAY LINGER WELL INTO THE EVENING. SOME
LIGHT FOG REDUCING VSBY'S TO 4-5SM IS EXPECTED AROUND SR ALONG WITH
SOME MVFR CIGS AT KHKY.
OUTLOOK...SCATTERED THUNDERSTORMS WILL OCCUR AGAIN THU AFTERNOON AS
A COLD FRONT MOVES ACROSS THE REGION. CONDITIONS WILL IMPROVE
SIGNIFICANTLY FOR FRIDAY AND SATURDAY BEHIND THE FRONT AS DRY HIGH
PRESSRUE BUILDS OVER THE REGION IN THE WAKE OF THE FRONT AND
HURRICANE ARTHUR. TYPICAL SUMMERTIME WEATHER WILL RETURN THE FRIST
OF NEXT WEEK WHICH MEANS SCATTERED AFTERNOON THUNDERSTORMS.
