The episode as NWS GSP wrote it up.
Scattered thunderstorms knocked down a few trees over upstate South Carolina.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before the first event at Apr 3, 2:58 PM EST, 2 hours 57 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 358 PM EDT TUE APR 3 2012 .SYNOPSIS... A FRONTAL BOUNDARY WILL REMAIN ACROSS THE AREA THROUGH WEDNESDAY PROVIDING FOR WARM UNSETTLED WEATHER. A RIDGE OF CANADIAN HIGH PRESSURE WILL GRADUALLY BUILD IN LATE THURSDAY INTO FRIDAY AND REMAIN ACROSS THE AREA OVER THE WEEKEND. && .NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/... 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 /20Z TUESDAY THROUGH SUNDAY/... AT KCLT...SCATTERED LOW CLOUDS PERSIST ACROSS THE PIEDMONT THIS AFTERNOON. THIS COULD FORM A BRIEF BROKEN CEILING...BUT CONTINUED WARMING OF THE BOUNDARY LAYER SHOULD KEEP THE CLOUD BASE IN THE VFR RANGE. OTHERWISE...WIND WILL REMAIN S TO SW THROUGH THE EVENING. THE PIEDMONT WILL REMAIN FAR TO THE EAST OF ANY TRIGGER FOR THUNDERSTORM DEVELOPMENT...SO THIS WAS LEFT OUT OF THE FCST. WILL MONITOR FOR CHANGES THIS EVENING. WIND WILL COME AROUND MORE TO THE WSW ON WEDNESDAY. ELSEWHERE...A PATCH OF LOW MVFR STRATOCU WILL CONTINUE TO GRADUALLY LIFT AND SCATTER OUT ACROSS UPSTATE SC THROUGH THE MIDDLE AFTERNOON. THIS WILL KEEP AN MVFR CLOUD CEILING AT KGSP/KGMU/KAND THROUGH 20Z TO 22Z. ONCE THE CLOUDS SCATTER OUT...WE SHOULD SEE MUCH DEEPER CONVECTION DEVELOP WITHIN AN HOUR OR TWO...SO A CB CLOUD GROUP WAS INDICATED AFTER 22Z. KAVL WILL BE MUCH CLOSER TO THE ACTION THROUGH LATE AFTERNOON AND ONGOING THUNDERSTORMS OVER THE BALSAMS AND SMOKIES ARE DRIFTING TOWARD THE FR BROAD VALLEY. AN AMENDMENT MIGHT BE NECESSARY BY 19Z. KHKY WILL BE SIMILAR TO KCLT...BUT WITH CLOUDS PLENTIFUL ENOUGH TO CONSTITUTE A CEILING AROUND 040. THE CONVECTION WILL LINGER ACROSS THE REGION INTO THE EVENING BEFORE WEAKENING. KAVL WILL HAVE THE BEST POTENTIAL RIGHT NOW FOR DENSE FOG AROUND DAYBREAK. THE LATEST MODEL GUIDANCE SUGGESTS IT WILL BE CLOUDY OVERNIGHT WHICH MIGHT IMPEDE FOG DEVELOPMENT. HOWEVER...ANY RAIN AT THE TAF SITE MIGHT PROVIDE ENOUGH LOW MOISTURE AND COOL IT OFF ENOUGH THAT FOG WOULD DEVELOP ANYWAY. THE FOG WAS TAKEN OUT FOR THIS ISSUANCE BUT IT IS EQUALLY LIKELY TO BE PUT BACK IF THERE IS MORE OF AN INDICATION THAT IT WILL CLEAR OFF LATE TONIGHT. ON WEDNESDAY... LOW CLOUDS SHOULD NOT BE AS PLENTIFUL. OUTLOOK...ISOLATED TO SCATTERED MAINLY DIURNAL SHOWERS AND TSTMS WILL BE POSSIBLE THRU THE WEEK...WITH ASSOC FLIGHT RESTRICTIONS. TSTM CHC WILL INCREASE WEDNESDAY AFTERNOON AS A COLD FRONT APPROACHES FROM THE WEST. COLD AIR DAMMING MAY BRING WIDESPREAD LOW CIGS AND VSBYS BY THURSDAY OR THURSDAY NIGHT.
