Area forecast discussion, Apr 3, 9:46 PM EDT, 1 hour 24 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
946 PM EDT TUE APR 3 2012

.SYNOPSIS...
A FRONTAL BOUNDARY WILL REMAIN ACROSS THE AREA THROUGH FRIDAY...
PROVIDING FOR WARM UNSETTLED WEATHER. A RIDGE OF CANADIAN HIGH
PRESSURE WILL BUILD IN FOR THE WEEKEND.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
AS OF 925 PM...STRONGER CONVECTION WILL BE MOVG E OF THE CWA IN THE
NEXT COUPLE HOURS BUT BUMPED POPS UP IN THE SE CWA AGAIN FOR THIS
UPDATE. TWEAKED TEMP/DP AND RH AS WELL.

AS OF 740 PM...CONVECTION WILL LINGER THIS EVE WITH SCT SHWRS AND
ISOLD TSTMS PSBL...ESP MTNS AND AREAS OF LINGERING INSTABILITY.
ADJUSTED FCST GRIDS ACCORDINGLY FOR THIS UPDATE.

AS OF MID AFTERNOON...KGSP RADAR CONTINUES TO LIGHT UP ACROSS THE
CENTRAL AND SRN MTNS...WHERE RIDGETOP CONVECTION CONTINUES TO
ORGANIZE A COLD POOL. THIS ACTIVITY SHOULD HAVE NO PROBLEM MOVING
ALL THE WAY TO THE BLUE RIDGE. EXPECT MORE SEVERE STORMS TO CONTINUE
ACROSS THE MTNS INTO THE LATE AFTERNOON.EAST OF THERE...LONGER TERM
PROSPECTS ARE MUCH LESS CERTAIN. THE VISIBLE IMAGERY SHOWS THE
REMNANT OF MORNING LOW STRATUS COVERING MOST OF UPSTATE SC AND NE
GEORGIA... WHICH HAS PREVENTED DESTABILIZATION. OVER THE NC
FOOTHILLS...DRIER AIR HAS ALSO LIMITED THE AMOUNT OF BUOYANCY. THINK
THE ACTIVITY WILL SURVIVE INTO THE NC FOOTHILLS BUT WILL HAVE
TROUBLE REACHING MUCH INTO THE PIEDMONT WHERE DEWPTS ARE IN THE LOW
50S. THERE IS STILL TIME FOR NE GEORGIA AND THE UPSTATE TO BREAK
OUT...SO A CHANCE WILL BE INCLUDED THERE INTO THE EARLY EVENING.

THE MODELS INDICATE THAT CONVECTION MAY CONTINUE WELL INTO THE
OVERNIGHT HOURS AS LIGHT SW FLOW CONTINUES TO ADVECT MOISTURE INTO
THE REGION AND WEAK WARM ADVECTION SUPPORTS ADDITIONAL DEVELOPMENT.
MIN TEMPS SHOULD BE MILD ONCE AGAIN...AND WERE KEPT NEAR A BLEND OF
THE MAV AND MOSGUIDE. LOW CLOUDS WILL NOT BE AS EXTENSIVE AS THIS
PAST NIGHT...HOWEVER.

EXPECT WEDNESDAY TO BE ANOTHER CONVECTIVELY ACTIVE DAY...WITH BETTER
UPPER SUPPORT IN THE FORM OF A WEAK SHORT WAVE COMING OVER TOP OF
THE UPPER RIDGE. SOME WEAK UPPER DIVERGENCE SHOULD ALSO CONTRIBUTE.
THE TIMING OF THE SHORT WAVE MAY TRIGGER THE DEVELOPMENT A BIT
EARLIER IN THE DAY. THE PRECIP CHANCES WILL BE RAMPED UP TO THE HIGH
END OF THE CHANCE RANGE...WHICH COULD GO HIGHER BASED ON THE VERY
HIGH POP ON THE 09Z SREF. A GUIDANCE BLEND WAS USED FOR MAX TEMPS.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH THURSDAY NIGHT/...
AS OF 240 PM TUESDAY...SUNRISE THURSDAY...SHORT RANGE MODELS
INDICATE THAT THE CENTER OF A CLOSED MID LEVEL LOW WILL BE LOCATED
OVER THE MID MISSISSIPPI RIVER VALLEY. THE LOW WILL SWING EAST
DURING THE DAY...PLACING THE CWA UNDER THE BULK OF THE SYNOPTIC
SCALE FORCING. IN ADDITION...TEMPERATURES MAY PEAK IN THE LOW TO MID
70S WITH DEWPOINTS IN THE MID 50S. CAPES SHOULD POOL BETWEEN 1000 TO
1500 J/KG DURING THE AFTERNOON SOUTH OF I-40. THE COMBINATION OF
STRONG QG FORCING AND INSTABILITY SHOULD RESULT IN A RAPID INCREASE
IN POPS AFTER SUNRISE THURSDAY. COVERAGE OF SHRA AND SOUTHERN TSRA
SHOULD CONTINUE TO INCREASE INTO THE EVENING AS MID LEVEL LOW/TROF
MOVES ACROSS THE SOUTHERN APPALACHIANS AND A BACK DOOR SFC FRONT
PUSHES SOUTH. I WILL INDICATE A DECREASING CHC IN TSRA AS STABLE CAD
SLOWLY BUILDS SW DURING THE EVENING HOURS.

FRIDAY...SYNOPTIC FORCING WILL TRACK EAST DURING THE MORNING
HOURS...HEIGHTS WILL LIKELY BEGIN TO INCREASE FROM THE WEST DURING
THE AFTERNOON. AT THE LLVL...WINDS WILL REMAIN NE WITH WEAK CAD
LINGERING. ALSO...H925 MOISTURE REMAINS VERY HIGH ACROSS THE
FOOTHILLS AND PIEDMONT...ESPECIALLY ACROSS SC AND GA. IT APPEARS
THAT CAD WILL LINGER THROUGH MOST OF THE DAY. THE COMBINATION OF THE
NE WINDS AND CLOUDS SHOULD KEEP DAYTIME TEMPERATURES IN THE U50S TO
L60S...OR 5 TO 8 DEGREES BELOW NORMAL. POPS WILL COME TO AN END ON
FRIDAY.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
AS OF 355 PM TUESDAY...LARGE CANADIAN HIGH PRESSURE WILL BUILD ACROSS
THE REGION BY SATURDAY MORNING. H85 TEMPS WILL COOL BELOW 5C...WITH
CLEARING SKY CONDITIONS AND LIGHT WINDS. SATURDAY MORNING LOW
TEMPERATURES WILL RANGE FROM AROUND 40 ACROSS THE MTNS TO L40S
EAST...WHICH IS ONLY SLIGHTLY BELOW NORMAL. HIGHS SHOULD REACH U60S
TO L70S. THE CANADIAN AIR MASS WILL LINGER INTO SUNDAY...RESULTING
IN SLIGHTLY MODIFIED TEMPERATURES WITH CONTINUE DRY CONDITIONS.
MONDAY AND TUESDAY...A WEAK COLD FRONT WILL SWEEP ACROSS THE REGION.
MON TEMPERATURES MAY PEAK A COUPLE OF DEGREES OVER SUNDAY/S VALUES.
WEAK CAA ON TUESDAY SHOULD FAVOR MID 60S ACROSS THE MTNS WITH L70S
EAST...I WILL INDICATE SCHC POPS FOR SHRA.

&&

.AVIATION /02Z WEDNESDAY THROUGH SUNDAY/...
AT KCLT...GUIDANCE AND TRENDS INDICATE SCT SHWRS WILL MOVE IN BEFORE
DYING OFF. HAVE TEMPO -SHRA FOR A COUPLE HOURS THIS EVE. MAIN
CONCERN LATER WILL BE FOG...KEPT IT AT MVFR AROUND DAYBREAK BUT
COULD BE WORSE IF THERE IS SUFFICIENT RAIN THIS EVE AND ENOUGH
CLEARING OVERNIGHT. LGT SW WINDS OVERNIGHT WILL BECOME GUSTY WED
AFTN. EXPECT SCT CONVECTION WED AFTN.

ELSEWHERE...GUIDANCE AND TRENDS INDICATE CONVECTION WILL LINGER A
FEW HOURS BEFORE DYING OFF. HAVE TEMPO -SHRA ALL TERMINALS FOR A
COUPLE HOURS THIS EVE...-TSRA AT KAND ONGOING. MAIN CONCERN LATER
WILL BE FOG. MAINLY MVFR AROUND DAYBREAK BUT EARLIER AND LIKELY IFR
AT KAND WHERE HEAVY RAIN FELL...PSBLY ELSEWHERE AS WELL. SW WINDS
PICK UP WITH MIXING...NW KAVL. EXPECT SCT CONVECTION WED AFTN.

OUTLOOK...ISOLD TO SCT MAINLY DIURNAL SHOWERS/TSTMS PSBL THRU THE
WEEK WITH ASSOC RESTRICTIONS. CHC TSTM WILL INCREASE WEDNESDAY
AFTERNOON AS A COLD FRONT APPROACHES FROM THE WEST. COLD AIR DAMMING
MAY BRING WIDESPREAD LOW CIG/VSBY THU-THU NIGHT. DRY RIDGE BUILDS IN
FOR THE WEEKEND.
