AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
750 PM EDT MON JUL 20 2015
.SYNOPSIS...
THE REGION WILL STAY WARM AND HUMID THROUGH TUESDAY...WHEN A WEAK
COLD FRONT MOVES INTO THE AREA. THE FRONT WILL STALL JUST TO THE
SOUTH OF THE REGION THROUGH THE REMAINDER OF THE WEEK...RETURNING
TEMPERATURES TO NEAR NORMAL. A CHANCE OF SHOWERS AND THUNDERSTORMS
WILL CONTINUE EACH DAY THROUGH THE PERIOD AS THE AREA REMAINS
UNDERNEATH A BROAD EAST COAST TROUGH...TO THE EAST OF A DEEP RIDGE
OVER THE PLAINS.
&&
.NEAR TERM /THROUGH TUESDAY/...
AS OF 740 PM EDT...PRECIPITATION CHANCES HAVE BEEN BRIEFLY BOOSTED
OVER THE MTNS AND IMMEDIATELY ADJACENT FOOTHILLS...BUT THE LATEST
CONVECTION ALLOWING MODELS HAVE THIS ACTIVITY STEADILY DISSIPATING
EAST OF THE MTNS THROUGH THE EVENING HOURS. SBCAPE VALUES OF 1000 TO
2000 J/KG PERSIST...AND BETTER DCAPE OVER THE SE HALF WILL MAINTAIN
AN ISOLD SEVERE THREAT FOR ANY CELLS THAT MANAGE TO HOLD TOGETHER
EAST OF THE MTNS. ANTICIPATE THE MTN ACTIVITY TO TRANSFORM IN A
BRIEF STRATIFORM RAIN SHIELD BEFORE ENDING TOWARD MIDNIGHT. EXPECT
MAINLY DEBRIS CLOUDS OVERNIGHT WITH PATCHY FOG IN AREAS THAT
RECEIVED HEAVY RAINFALL. MIN TEMPS WILL REMAIN MILD WITH MID TO
UPPER 60S MTNS AND LOW TO MID 70S PIEDMONT.
TUESDAY COULD BE A BIT MORE INTERESTING AS UPPER HEIGHTS FALL WITH A
SHORT WAVE DROPPING ACROSS THE GREAT LAKES/UPPER OH VALLEY/NE.
HOWEVER...THE MODELS SUGGEST THIS MAY HAPPEN EARLIER IN THE
DAY...PERHAPS BEFORE WE GET ANY SUBSTANTIAL HEATING. THAT TIMING
WOULD CARRY THE BEST MID/UPPER SUPPORT TO THE EAST IN THE 15Z TO 18Z
TIME FRAME...BUT A BOUNDARY WOULD BE LEFT TO LAY OUT ACROSS THE FCST
AREA THRU THE AFTERNOON. THE GFS ONLY DEVELOPS NEW CONVECTIVE PRECIP
OVER THE MTNS...WHICH SEEMS UNDERDONE WITH A BOUNDARY IN THE
VICINITY. THE NAM LOOKS BETTER AND IS FAVORED...SO THE FCST
CONTINUES TO FEATURE A CHANCE ACROSS THE WHOLE FCST AREA...ALBEIT
HIGHEST TOWARD THE TN BORDER. CANNOT RULE OUT A FEW SEVERE STORMS
AGAIN...BUT ONCE AGAIN...THE BETTER CHANCE WILL BE TO THE NORTH
WHERE THE BETTER FORCING WILL BE. HIGH TEMPS WILL BE A DEGREE OR TWO
LESS...WHICH SHOULD KEEP THE HEAT INDEX BELOW ADVISORY CRITERIA.
&&
.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
AS OF 215 PM...AN UPPER LOW WILL SWING FROM NEAR JAMES BAY...SE
TOWARD NORTHERN MAINE THROUGH THURSDAY WHICH WILL LOWER HEIGHTS
ACROSS THE EASTERN U.S. AT THE SURFACE...A WEAK COLD FRONT IS
FORECAST BY ALL GUIDANCE SOURCES TO MOVE THROUGH THE WESTERN
CAROLINAS AND NE GA TUE NIGHT AND SETTLE PERHAPS INTO THE SC
MIDLANDS AND NORTH CENTRAL GA ON WED. THE GFS CONTINUES TO SHOW THE
FRONT MAKING PROGRESS FARTHER SOUTH THAN THE NAM WHICH RESULTS IN
LOWER DEWPOINTS AND A MORE STABLE ENIVRONMENT ACROSS THE AREA ON
WED. THE NAM ON THE OTHER HAND ALLOWS THE AIRMASS TO MOISTEN QUICKLY
WED AFTERNOON WITH A CONVECTIVE COMPLEX THEN MOVING THROUGH THE
MOUNTAINS INTO THE FOOTHILLS BY WED EVENING TRIGGERED BY A SHORT
WAVE IN THE NW FLOW ALOFT. THE TRUTH PROBABLY LIES SOMEWHERE IN
BETWEEN THESE TWO SOLUTIONS. A MODEL BLEND RESULTS IN SCT
SHOWERS/THUNDERSTORMS DEVELOPING OVER THE MOUNTAINS IN THE AFTERNOON
TRIGGERED BY THE WEAK SHORT WAVE RIPPLING ALONG IN THE NW FLOW. THIS
UPPER WAVE IS FORECAST TO GENERATE A LOW ON THE FRONTAL BOUNDARY
ACROSS THE SC MIDLANDS WED NIGHT. HENCE...SOME SCT SHOWERS/STORMS
ASSOCIATED WITH THE FRONTAL LOW MAY THEN AFFECT THE REST OF THE AREA
WED NIGHT IN EARLY THURSDAY. ON THURSDAY...THE SHOWERS ASSOCIATED
WITH LOW SHOULD PULL EAST OF THE AREA WITH THE MAJORITY OF THE DAY
BEING BECOMING MOSTLY DRY. THE HOT TEMPS WILL BE MITIGATED SOMEWHAT
WITH THE ARRIVAL OF THE FRONT...BUT STILL REMAIN A LITTLE ABOVE
CLIMO.
&&
.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
AS OF 245 PM MONDAY...THE EXTENDED PERIOD BEGINS ON THURSDAY NIGHT
WITH THE UPPER TROUGH PERSISTING ACROSS THE EAST COAST. AN
UPPER-LEVEL RIDGE PERSISTS OVER THE SOUTHERN PLAINS...PLACING THE
REGION IN FAMILIAR NORTHWEST FLOW ALOFT. AT THE SURFACE...A
QUASI-STATIONARY FRONT WILL BE LOCATED NEAR OR OVER THE FORECAST
AREA AND ITS EXACT LOCATION WILL DETERMINE EXACTLY HOW MUCH OF THE
FORECAST AREA WILL BE STABLE AND DRY HEADING INTO THE WEEKEND.
NEVERTHELESS...THE UPPER-LEVEL PATTERN WILL GENERALLY PERSIST
HEADING INTO MONDAY AND TUESDAY...WHEN THE RIDGING OVER THE SOUTHERN
PLAINS EXPANDS NORTH AND EAST AND DEEPENS SLIGHTLY IN RESPONSE TO
THE EAST COAST TROUGH LIFTING NORTH AND EAST INTO NEW ENGLAND. THE
AFOREMENTIONED FRONT WILL SLOWLY PROPAGATE TOWARDS THE GULF COASTAL
PLAIN WHILE BEHIND THE FRONT...HIGH PRESSURE CENTERED ACROSS THE
EASTERN GREAT LAKES NOSES SOUTH INTO OUR REGION BY FRIDAY. BY
SATURDAY...THE SURFACE HIGH PRESSURE AND ASSOCIATED RIDGE AXIS
SHIFTS OFFSHORE...TRANSITIONING OUR LOW-LEVEL FLOW TO A
SOUTHEASTERLY DIRECTION IN ADVANCE OF ANOTHER WEAK FRONT APPROACHING
FROM THE OHIO VALLEY. GUIDANCE IS IN GENERAL AGREEMENT ABOUT
BRINGING THE REMNANTS OF THIS BOUNDARY ACROSS THE AREA SUNDAY
NIGHT...BUT THE GENERAL SE TO SOUTHERLY LOW-LEVEL FLOW WILL PERSIST
THROUGH THE END OF THE PERIOD ON TUESDAY MORNING.
IN TERMS OF SENSIBLE WEATHER...AT THIS TIME THE PREVIOUSLY MENTIONED
SURFACE FRONT NEAR OUR AREA ON FRIDAY SHOULD WORK TO ENHANCE POPS TO
MID-CHANCE ACROSS THE SOUTHERN PORTIONS OF OUR AREA...WHILE THE
DRIER AND MORE STABLE AIRMASS BEHIND THE FRONT SHOULD CAP POPS TO
SLIGHT CHANCE ACROSS THE WESTERN CAROLINAS. HEADING INTO
SATURDAY...THE AREA SHOULD CONTINUE TO EXPERIENCE NEAR TO BELOW
NORMAL POPS BUT THE SOUTHEASTERLY LOW-LEVEL FLOW MAY INDUCE
CONVECTION ALONG THE FAVORED UPSLOPE AREAS OF THE BLUE RIDGE AND
APPALACHIANS AS CAPE VALUES START TO RECOVER...ESPECIALLY SOUTH AND
WEST. BY SUNDAY EVENING...CHANCE POPS ACROSS THE AREA IN ADVANCE OF
THE APPROACHING FRONTAL BOUNDARY WILL PERSIST AT A MINIMUM INTO
EARLY TUESDAY AS THE REMNANT TROUGH AXIS LINGERS NEAR THE AREA.
TEMPERATURES WILL RETREAT TO NEAR NORMAL ACROSS THE AREA BEHIND THE
FRONT ON FRIDAY...AND SHOULD STAY NEAR NORMAL UNTIL MONDAY...WHEN
SOME SLIGHT WARMING WILL BEGIN TO TAKE PLACE IN RESPONSE TO THE
BUILDING UPPER RIDGE.
AS OF 245 AM MONDAY...AN UPPER TROF WILL PERSIST ALONG THE EAST
COAST...WHILE A RIDGE BUILDS OVER THE GREAT PLAINS FOR LATE IN THE
WEEK INTO THE WEEKEND. THIS WILL KEEP THE CWFA UNDER NWLY DEEP-LAYER
FLOW...AND SHUD RESULT IN NEAR OR BELOW CLIMO POPS THRU THE MEDIUM
RANGE. BLENDING IN THE LATEST HPC AND 00Z MEDIUM RANGE GUIDANCE DID
TREND POPS DOWN...BUT STILL HAVE SLGT CHC TO LOW-END CHC OF DIURNAL
CONVECTION EACH DAY. TEMPS WILL ALSO BE NOT AS HOT AS THEY/VE BEEN
LAST FEW DAYS. HOVERING NEAR TO SLIGHTLY ABOVE NORMAL.
&&
.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
AT KCLT...MOST OF THE PIEDMONT CONVECTION WAS PASSING N AND S OF THE
AIRFIELD AT ISSUANCE TIME...AND VCSH SHOULD SUFFICE FOR THE REST OF
THE EVENING HOURS. CANNOT RULE OUT A ROGUE OUTFLOW...BUT WINDS
SHOULD REMAIN WSW ON AVERAGE. EXPECT DEBRIS CLOUDS OVERNIGHT...WITH
LITTLE CHANCE OF FOG OR LOW CLOUDS UNLESS THE AIRFIELD GETS AN
UNEXPECTED HEAVY RAIN SHOWER. MIXING WILL BRING IN SOME WSW GUSTS ON
TUE WITH BETTER FLOW NEAR THE TOP OF THE MIXED LAYER. TSTM CHANCES
WILL BE HARD TO TIME ON TUE WITH THE UPPER SUPPORT POSSIBLY PASSING
MID DAY BUT WITH BETTER INSTABILITY MID TO LATE AFTN. WILL FEATURE A
PROB30 FOR TSRA STARTING AT 18Z FOR NOW.
ELSEWHERE...THE LINE OF BKN TSRA COMING EAST OFF THE BLUE RIDGE WILL
CERTAINLY IMPACT KAVL WITH GUSTY NW WINDS...AND MAY REACH OUT TO THE
FOOTHILL TAFS THROUGH MID TO LATE EVENING. WILL KEEP TEMPO TSRA
GOING AT KHKY AND WILL HAVE TO MONITOR THE UPSTATE FOR A BRIEF TEMPO
TSRA ADDITION IF THE CELLS SURVIVE THE TRIP OFF THE HIGHER TERRAIN.
OTHERWISE...EXPECT MAINLY DEBRIS CLOUDS OVERNIGHT EXCEPT FOR PATCHY
LOW CLOUDS AND FOG WHEREVER HEAVY RAIN FALLS. WSW WINDS WILL COME UP
WITH MIXING ON TUE...EXCEPT WINDS REMAINING NW AT KAVL...WITH GUSTS
IN THE UPPER TEENS TO AROUND 20 KT DURING THE AFTN. LIKE
KCLT...CONVECTION WILL BE DIFFICULT TO TIME GIVEN AN EARLY UPPER
WAVE PASSAGE...BUT WITH BETTER INSTABILITY BY LATE AFTN. WILL
FEATURE PROB30 TSRA AFTER 18Z.
OUTLOOK...A WEAK FRONTAL BOUNDARY DROPPING SWD ACROSS THE AREA MAY
STALL JUST SOUTH OF THE TERMINAL FORECAST AREA MID TO LATE WEEK.
THIS WILL LEAD TO A DIURNAL PATTERN OF CONVECTION EACH DAY...WITH
CHANCES OF MORNING FOG/STRATUS MAINLY WHERE RAIN FELL THE PREVIOUS
DAY.
