LIEBLWhat 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 Sioux Falls, SD wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 10, 10:15 AM CDT, 3 hours 52 minutes earlier.
Area forecast discussion, Aug 10, 10:15 AM CDT, 3 hours 52 minutes before
AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA NATIONAL WEATHER SERVICE SIOUX FALLS SD 1015 AM CDT FRI AUG 10 2007 .DISCUSSION... SHOWERS AND THUNDERSTORMS IN ERN SD HAVE DIED OFF THIS MORNING IN THE WAA ZONE. FOCUS NOW TURNS INTO SOUTH CENTRAL SD WHERE THUNDERSTORMS ACTIVITY HAS INCREASED IN THE LAST FEW HOURS. THIS ACTIVITY IS ALONG THE LOW LEVEL JET AND AHEAD OF THE UPPER WAVE EJECTING OUT OF WY. CONVECTION WILL CONTINUE THOUGH THE MORNING HOURS WHILE MOVING EAST TO NORTHEAST AT 25 MPH...BUT SHOULD BEGIN TO WANE THIS AFTERNOON. AT THIS TIME...NOT EXPECTING SEVERE WEATHER WITH THESE STORMS...HOWEVER IT IS NOT OUT OF THE QUESTION. SMALL HAIL AND WIND GUST TO 50 MPH LIKELY WITH STRONGER STORMS. MAIN SEVERE WEATHER THREAT STILL LATE AFTERNOON AND EVENING ACROSS THE NE SD INTO ERN ND WITH THE BETTER DYNAMICS...BUT WILL WATCH S/WV ENERGY OVER SE WY...AS IF COULD BE A TRIGGER MECHANISM FOR STRONGER STORMS IN SE SD. && .AVIATION... GENERALLY VFR CONDITIONS WILL PREVAIL FOR TODAY...THOUGH ISOLATED SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE NEAR THE TAF SITES THROUGH 15Z...WITH UPPER END MVFR VISIBILITIES IN STORMS. SCATTERED THUNDERSTORMS WILL BE POSSIBLE AGAIN AROUND KHON AFTER 20Z. && .PREV DISCUSSION... FOCUS FOR TODAY IS CONVECTIVE CHANCES...ESPECIALLY OVER THE NEXT 24 HOURS AND AGAIN LATER IN THE WEEKEND. FOR TODAY...LINE OF SCATTERED THUNDERSTORMS HAS BEEN PERSISTING WITH VERY SLOW EASTWARD MOVEMENT ACROSS WESTERN CWA EARLY THIS MORNING. TSRA TIED TO AXIS OF INSTABILITY AND MID LEVEL THETA-E ADVECTION... WHICH TRAVERSES SLOWLY EASTWARD INTO CENTRAL PORTIONS OF THE CWA BY MIDDAY...AND INTO THE NORTHEAST BY LATE AFTERNOON. HAVE TRANSITIONED CHANCE POPS EAST WITH THIS AREA OF ADVECTION THRU EARLY AFTERNOON... TAPERING VALUES DOWN TOWARD THE NORTHEAST FOLLOWING TYPCIAL DIURNAL TRENDS FOR STORMS WEAKENING AS NOCTURNAL LOW LEVEL JET DECREASES. MAIN QUESTION FOR THIS AFTERNOON/EVENING IS WHAT IMPACT CONVECTIVE DEBRIS AND POTENTIAL WEAK OUTFLOW BOUNDARIES FROM MORNING ACTIVITY WILL HAVE ON CHANCE FOR REDEVELOPMENT LATER IN THE AFTERNOON. MODELS SIMILAR IN STRENGTHENING SURFACE LOW OVER FAR WESTERN DAKOTAS BY LATE AFTERNOON AS UPPER WAVE CROSSES THE NORTHERN ROCKIES. MODEL DIFFERENCES ARE GREATER IN PLACEMENT OF WARM FRONT WHICH EXTENDS EAST OF THE LOW ACROSS THE NORTHERN PLAINS. GFS/ECMWF DRAPE WARM FRONT ACROSS SD INTO FAR NORTHERN COUNTIES OF OUR CWA BY LATE AFTERNOON. NAM LIFTS MAIN WARM FRONT WELL NORTH INTO ND/NRN MN... THOUGH 00Z RUN DOES HINT AT SECONDARY BOUNDARY NEAR OUR NORTHERN CWA BORDER AS WELL. PLACEMENT OF FRONT IN THIS LOCATION ALLOWS FOR IMPRESSIVE DEEP LAYER SHEAR VALUES ACROSS THE NORTHERN CWA BY 00Z. HOWEVER FORECAST SOUNDINGS SHOW MUCH OF THIS SHEAR IS IN LOWEST 3KM...AND WITH STRONG WARMING IN 850-700MB LAYER...WILL BE DIFFICULT FOR STORMS TO BECOME SURFACE BASED AND TAP INTO THE BEST SHEAR. WILL MENTION SEVERE POTENTIAL IN HWO...CONCENTRATED ACROSS NORTHERN TWO TIERS OF COUNTIES FOR HAIL THREAT WITH ISOLATED ELEVATED SUPERCELLS. BETTER THREAT FOR ORGANIZED SEVERE WEATHER APPEARS TO BE NORTH OF OUR AREA...WHERE LIFT WILL BE ENHANCED BY UPPER WAVE AND LEFT EXIT REGION OF WEAK JET AXIS FROM SWRN SD INTO WEST CNTRL MN. MOST LIKELY AREA FOR SURFACE BASED DEVELOPMENT WILL BE IN SOUTHWEST CWA DURING THE LATE AFTN... WHERE SURFACE TEMPS NEARING 100F COULD POTENTIALLY BREAK THROUGH THE STRENGHTENING CAP. SHEAR NOT AS GREAT IN THIS AREA THOUGH...AND WITH VERY WARM TEMPS ALOFT...STORMS WILL HAVE TO BECOME QUITE STRONG FOR SEVERE HAIL TO REACH THE SURFACE. WAVE EXITS EAST OF OUR AREA BY EARLY SATURDAY MORNING...AND WARM MID LEVELS SHOULD SUPPRESS ANY CHANCE AT CONVECTIVE DEVELOPMENT AS COOL FRONT PUSHES SOUTHEAST THROUGH THE CWA SATURDAY AFTERNOON/EVENING. TEMPERATURES TODAY WILL PUSH TRIPLE DIGITS WEST OF THE JAMES VALLEY. MAY FLIRT WITH HEAT ADVISORY CRITERIA BRIEFLY IN THESE AREAS THIS AFTERNOON...THOUGH DEEP MIXING REQUIRED TO REACH THE HIGHER TEMPS SHOULD ALSO BRING DOWN SLIGHTLY DRIER DEW POINTS AND KEEP US JUST SHY OF CRITERIA. GREATER CONCERN FOR ADVISORY CONDITIONS IN SOUTH CENTRAL/SOUTHEAST CWA SATURDAY AFTERNOON...WHERE IT MAY BE HARDER TO MIX OUT HIGHER MOISTURE LEVELS DUE TO RECENT RAINS...AS WELL AS EVAPOTRANSPIRATION FROM STILL GREEN CORN CROPS. WILL HOLD OFF FOR NOW DUE TO UNCERTAINTY IN AFTERNOON DEW POINT LEVELS...BUT WILL BE SOMETHING FOR NEXT SHIFT TO LOOK AT. CONTINUING TO FOLLOW GFS MORE CLOSELY IN FRONTAL PLACEMENT LATER SATURDAY NIGHT/SUNDAY...HANGING BOUNDARY UP NEAR OR JUST NORTH OF I-80...AS OPPOSED TO NAM WHICH DRIVES THE FRONT CLOSER TO I-70 BY LATE SUNDAY AFTERNOON. HAVE KEPT SOME LOW POPS GOING IN THE FAR SOUTH SUNDAY...AND SPREADING OVER THE ENTIRE CWA SUNDAY NIGHT WITH STRONG RETURN WARM ADVECTION. NO CHANGES TO LATER PERIODS OF THE FORECAST AT THIS TIME. 00Z OPERATIONAL GFS BRINGS COOL FRONT BACK THROUGH THE REGION BY MONDAY AFTERNOON ALREADY...BUT HAD LITTLE SUPPORT FROM REMAINDER OF GFS ENSEMBLE MEMBERS WHICH FAVORED SLOWER TIMING SIMILAR TO GOING FORECAST. && .FSD WATCHES/WARNINGS/ADVISORIES...
