07What forecasters said that day
The local office's own words before this severe thunderstorm warning went out, 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 this severe thunderstorm warning went out at Jul 1, 10:25 PM EDT, 45 minutes earlier.
Area forecast discussion, Jul 1, 10:25 PM EDT, 45 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC 1025 PM EDT SUN JUL 1 2012 .SYNOPSIS... STRONG AND DEEP LAYERED HIGH PRESSURE WILL CONTINUE TO PRODUCE WELL ABOVE NORMAL TEMPERATURES OVER THE COUPLE OF DAYS. SOME RELIEF WILL BEGIN BY MID WEEK...HOWEVER ABOVE NORMAL TEMPERATURES WILL PERSIST INTO THE WEEKEND. && .NEAR TERM /THROUGH MONDAY/... 0230 UTC UPDATE...POPS AND QPF HAVE BEEN INCREASED IN THE UPPER SAVANNAH RIVER VALLEY AND THE INTERSTATE 77 CORRIDOR IN SC BASED ON RADAR TRENDS. AT 10 PM EDT SUNDAY...AN ANOMALOUS UPPER TROUGH WAS LOCATED ALONG THE EAST COAST THIS EVENING...WHILE AN UPPER RIDGE WAS CENTERED OVER THE WESTERN PLAINS. OUR AREA REMAINS AN UNSTABLE AIR MASS...WITH SUBSTANTIAL CAPE OVER THE SW PORTION OF THE AREA WHERE THE LEAST CONVECTION HAS OCCURRED. WITH SEVERE THUNDERSTORMS CONTINUING...THE SEVERE THUNDERSTORM WATCH WILL EXTENDED IN TIME ONE HOUR IN UPSTATE SC. THE NC COUNTIES WILL BE CLEARED FROM THE WATCH. RADAR SHOWS NEW CONVECTION DEVELOPING FORM THE GREAT SMOKE MOUNTAINS TO THE KGSP AREA...AND THIS IS LIKELY TO CONTINUE FOR SEVERAL HOURS. SATELLITE IMAGERY SHOWS ANOTHER BAND OF CONVECTION IN THE OH RIVER VALLEY... THAT MAY SURVIVE TO CROSS THE APPALACHIANS. IT APPEARS THAT IF THIS SECOND ROUND OF ACTIVITY MAKES IT INTO OUR AREA...IT WOULD BE THE NORTHERN MOST PORTION OF OUR AREA IN NC. MINIMUM TEMPERATURES WILL BE ABOVE NORMAL UNDER THE INFLUENCE OF THE EASTERN EXTENSION OF THE UPPER RIDGE...BUT FORECAST VALUES HAVE BEEN LOWERED SEVERAL DEGREES EAST OF THE MOUNTAINS...AS RAINFALL HAS ALREADY LOWERED TEMPERATURES BELOW THE PREVIOUS FORECAST MINIMUMS. WITH THE RIDGE BREAKING DOWN SOMEWHAT...AND THE ASSOCIATED ENHANCED MCV POTENTIAL...NOT TO MENTION ANOTHER DAY OF VERY UNSTABLE AIR...COVERAGE OF CONVECTION SHOULD BE SLIGHTLY BETTER TOMORROW...ESP ACROSS THE NC ZONES. 30-40 POPS WILL BE CARRIED FOR MOST OF THE AREA. IT IS NOT EXPECTED TO BE AS HOT TOMORROW...DUE TO SLIGHTLY LOWER THICKNESS VALUES. ALTHOUGH HEAT ADVISORY CRITERIA MAY BE REACHED ACROSS PORTIONS OF THE PIEDMONT...IT DOESNT APPEAR AN EXCESSIVE HEAT WATCH IS NECESSARY ATTM. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/... AS OF 225 PM SUNDAY...THE CENTER OF THE H590 RIDGE WILL REMAIN CENTERED OVER THE FL PANHANDLE TUESDAY AND WEDNESDAY. THE SHIFT IN THE RIDGE WILL PLACE THE FORECAST AREA IN WEAK NW FLOW ALOFT. THE NAM...GFS...AND ECMWF INDICATE THAT CONVECTION IS POSSIBLE ACROSS THE REGION DURING THE AFTERNOON AND EVENING ON TUESDAY. FORECAST SOUNDINGS FROM THE GFS INDICATE THAT MID LEVEL TEMPS MAY WARM SLIGHTLY FROM TODAY AND MONDAY...RESULTING IN SHALLOWER LAPSE RATES. I WILL FORECAST CHC POPS OVER THE MTNS DURING THE EARLY AFTERNOON...THEN CHC POPS EXPANDING EAST OF THE MTNS DURING THE LATE AFTERNOON AND EVENING. HIGHS ARE FORECAST TO REACH WELL INTO THE U90S EAST OF THE MTNS...BUT LIKELY BREAKING OUR CURRENT STREAK OF 100 OR GREATER. RECORD TEMPS MAY BE TIED OR BROKEN. ON INDEPENDENCE DAY...MODELS INDICATE THAT A MID LEVEL SHORT WAVE WILL RIPPLE TOWARD THE CWA DURING THE LATE AFTERNOON AND EVENING. THIS FEATURE WILL LIKELY STEEP LAPSE RATES AND PROVIDE SOME MID LEVEL SUPPORT. IN ADDITION...A LEE TROF SHOULD DEVELOP DURING THE AFTERNOON...AIDING IN LLVL MOISTURE CONVERGENCE. GIVEN THESE FEATURES AND DIURNAL INSTABILITY IT APPEARS THAT COVERAGE WILL BE A LITTLE GREATER ON THE 4TH. I WILL FORECAST 50 POPS OVER THE RIDGES AND 30S EAST. TEMPERATURES SHOULD RANGE FROM AROUND 90 WITHIN THE MTN VALLEYS TO MID TO U90S EAST...LIKELY SHORT OF RECORDS. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... AS OF 100 PM SUNDAY...DECENT MODEL AGREEMENT AND CONFIDENCE IS HAD IN THE EXT RANGE FCST. THE 00Z ECMWF IS A BIT OF AN OUTLIER WITH A BROAD UPPER RIDGE DOMINATING THE SE CONUS WX...WHILE THE 12Z GFS/CMC ALLOW FOR MORE DEEP LAYERED MERIDIONAL FLOW AND THUS A MORE ACTIVE MCS TRACK SCENARIO THROUGH MUCH OF THE PERIOD. THERE WILL BE AMPLE LLVL MOISTURE SUPPLIED BY THE H85 HIGH FLOW RETURNING EAST OUT OF THE GULF AND A FAIRLY DEFINITIVE LEE SIDE TROF FOR A FOCUSING REGION OF MOISTURE AND AFTERNOON CONVECTION EACH AFTERNOON. ALONG WITH THE PROBABLE NOCTURNAL MCS ACTIVITY...THE EXT RANGE SHOULD BE A BIT ABOVE NORMAL CONVECTIVELY WITH STRONG TO SEVERE STORMS DEVELOPING EACH DAY. MODEL SOUNDINGS INDICATE A STAGNANT SFC-H5 AIRMASS ON THU AND PW/S AROUND 1.7 INCHES. NO LLVL JET WILL BE IN THE VICINITY...YET STILL THE THREAT MAY BE THERE FOR PERSISTENT HEAVY PRECIP AND LOCALIZED FLOODING. MAX TEMPS WILL STILL BE HOT AS THE LLVL FLOW MAINTAINS A COMPONENT OF DOWNSLOPE WARMING IN A GENERAL LARGE SCALE SUBSIDENCE PATTERN. MAX TEMPS SHOULD BE IN THE L/M90S NON/MTNS AND U80S MTN VALLEYS EACH DAY. MIN TEMPS WILL ALSO REMAIN A COUPLE CATS ABOVE NORMAL THROUGH THE PERIOD. && .AVIATION /03Z MONDAY THROUGH FRIDAY/... AT KCLT...CONVECTION WILL LEAVE THE AREA AND DEPART TO THE SOUTHEAST EARLY THIS EVENING. A CONSENSUS OF MODEL DATA IS NOT SUPPORTIVE OF MORNING FOG RESTRICTIONS WILL BE CARRIED AT THIS TIME. SCATTERED LOW CLOUDS WILL REMAIN IN THE AREA. THERE IS A CHANCE THAT CONVECTION IN THE OH VALLEY WILL ARRIVE LATE TONIGHT...BUT THAT CHANCE IS TOO LOW TO MENTION AT THIS TIME. WINDS ARE EXPECTED TO BE LIGHT FROM THE SOUTH TONIGHT...AND LIGHT FROM THE NORTH ON MONDAY. CONVECTIVE WILL NOT BE MENTIONED IN THE TAF DUE TO LOW CONFIDENCE IN COVERAGE AND TIMING. ELSEWHERE...CONVECTION WILL DIMINISH AND MOVE OFF TO THE SOUTHEAST THIS EVENING. THE BEST CHANCE FOR DAYBREAK FOG RESTRICTIONS WILL BE AT KAVL...WHERE GUIDANCE LENDS SUPPORT...AND KHKY...WHERE RAINFALL OCCURRED THIS AFTERNOON. SCATTERED LOW CLOUDS WILL PERSIST INTO MONDAY. CONVECTIVE WILL NOT BE MENTIONED IN THE TAFS DUE TO LOW CONFIDENCE IN COVERAGE AND TIMING. OUTLOOK...GRADUAL INCREASE IN AIR MASS MOISTURE AND CHANGES IN STEERING FLOW MAY RESULT IN AN INCREASE IN TSRA POTENTIAL THROUGH THE WEEK.
