The episode as NWS GID wrote it up.
Despite a fairly favorable setup for severe thunderstorms on this Thursday afternoon and evening, the ingredients didn't quite come together across the vast majority of South Central Nebraska, with radar data suggesting only the presence of a few strong storms roaming counties along and north of Interstate 80. However, a delayed storm report received the next day revealed that a tiny fraction of the area did in fact experience a severe wind event: a Merrick County farmer reported a flipped irrigation pivot and significant crop damage in a localized area near Silver Creek. Although radar data was inconclusive regarding the severity of these winds (due in part to the lowest beam height situated 6,000 feet above ground level at that distance), a fairly strong reflectivity core did pass through that area around 9 p.m. CDT within an environment featuring strong low level wind shear (see below). A few hours prior to the Merrick County damage, northwestern portions of South Central Nebraska narrowly avoided a severe weather threat from a cluster of splitting supercells in Custer County. However, these storms weakened before entering local counties such as Dawson and Valley. Then, between 8-10 p.m. CDT, a handful of strong multicell storms flared up within the northeast quadrant of South Central Nebraska in response to a strengthening low level jet, including the Merrick County storm. While additional non-severe storms lingered over northeast counties such as Nance, Merrick and Polk past the midnight hour, all of South Central Nebraska was storm-free by 2:30 a.m. CDT.
This was a somewhat unusual severe weather setup by late-August standards, as a seasonably well-defined surface low and attendant eastward-arcing warm front became established over the heart of South Central Nebraska during the afternoon and evening. Although mid/upper level flow wasn't overly strong, a fairly compact vort max tracked over central Nebraska, well to the north of an expansive ridge anchored over northern Mexico. In addition, a seasonably-strong southerly low level jet ramped up to around 40 knots over much of central and eastern Nebraska by early evening. The combination of this low level jet and the underlying surface warm front yielded an impressive 30 knots of 0-1 kilometer low level wind shear around the time of the Merrick County wind damage. Other early-evening mesoscale parameters were more modest, including roughly 1000 J/kg most-unstable CAPE and 30 knots of deep-layer wind shear.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HASTINGS NE 700 PM CDT THU AUG 27 2015 .UPDATE... ISSUED AT 657 PM CDT THU AUG 27 2015 UPDATED THE EVENING FORECAST TO TACK ON DAWSON AND BUFFALO COUNTIES TO THE SEVERE THUNDERSTORM WATCH. AS THE THUNDERSTORMS NEAR THE SURFACE LOW ARE MOVING EAST SOUTHEAST. UPDATE ISSUED AT 609 PM CDT THU AUG 27 2015 UPDATED THE FORECAST TO INCLUDE A SEVERE THUNDERSTORM WATCH FOR MAINLY NORTHERN AND EASTERN AREAS OF THE COUNTY WARNING AREA...INCLUDING GRAND ISLAND. THERE COULD BE AN ISOLATED TORNADO IN THIS AREA AS WELL. && .SHORT TERM...(THIS EVENING THROUGH FRIDAY) ISSUED AT 338 PM CDT THU AUG 27 2015 MAIN CONCERN THROUGH THE SHORT TERM LIES WITH THE APPROACHING UPPER LEVEL DISTURBANCE MAKING ITS WAY OUT OF THE NRN/CENTRAL ROCKIES...AND THE RESULTING THUNDERSTORM CHANCES. HAVE STARTED TO SEE SOME SCATTERED LIGHT PRECIP DEVELOP ACROSS PORTIONS OF THE CWA ...WITH ACTIVITY EXPECTED TO INCREASE WITH TIME THE REST OF THIS AFTERNOON AND EVENING AS THE SYSTEM MOVES IN. AT THE SFC...CURRENTLY HAVE LOW PRESSURE CENTERED ROUGHLY OVER KMCK...A TROUGH AXIS EXTENDS NORTH INTO CENTRAL SD...WITH A WARM FRONT IN THE CENTRAL PORTIONS OF THE NEB/KS STATE LINE AND COLD FRONT SITTING OVER WRN KS. THERE HAS BEEN PLENTY OF CLOUD COVER ACROSS THE AREA...HELPING KEEP TEMPS NORTH OF THAT WARM FROM IN THE 80S. TO THE SOUTH ACROSS PART OF OUR KS COUNTIES...ESP IN AREAS AROUND PHG/HYS/RSL...GOOD MIXING TANKED DEWPOINTS INTO THE MID 50S...WHILE TEMPS ROSE TO NEAR EITHER SIDE OF 100 DEGREES. SPC MESO PAGE SHOWS MLCAPE VALUES IN EXCESS OF 2000 J/KG...WITH GRADUALLY DIMINISHING CAPPING REMAINING IN PLACE. HAS BEEN LITTLE CHANGE WITH THE GENERAL STORY WITH THE BRUNT OF THE THIS UPPER LEVEL DISTURBANCE BASICALLY PUSHING EAST NEAR THE NE/SD STATE LINE...WITH HI RES MODELS SHOWING ADDITIONAL ACTIVITY EXPECTED TO DEVELOP WITHIN THE COMING HOURS JUST OFF TO THE NW OF THE CWA...SLIDING INTO MAINLY NRN PORTIONS OF THE CWA THEREAFTER. KEPT THE HIGHER POPS ACROSS NRN THEN ERN PORTIONS OF THE CWA THIS EVENING/OVERNIGHT...COVERAGE ELSEWHERE LOOKS TO BE MORE SCATTERED IN NATURE. IN ADDITION TO THE INSTABILITY IN PLACE...MODELS SHOW THAT DEEPER LAYER SHEAR IS SUFFICIENT FOR SEVERE WEATHER TO BE A CONCERN...HAIL/DAMAGING WINDS REMAIN THE PRIMARY CONCERN...BUT CANT COMPLETELY RULE OUT AN ISOLATED TORNADO WITH THE SFC LOW/FRONTAL BOUNDARIES IN THE AREA. ACTIVITY WILL CONTINUE PUSHING EAST OVERNIGHT...AND HAVE POPS TRENDING DOWN BETWEEN 06-12Z. CONFIDENCE IN THE TIMING OF PRECIP MOVING OUT ISNT THE HIGHEST...THINKING FORECAST IS ON THE SLOWER SIDE...AND DID KEEP THE LINGERING 20 POPS INTO EARLY FRIDAY MORNING. THE REMAINDER OF THE DAYTIME HOURS FRIDAY IS DRY...WITH NORTHWESTERLY WINDS EVENTUALLY MOVING THROUGH THE ENTIRE CWA DURING THE MORNING BEHIND THE MAIN FRONT. NOT A SIGNIFICANTLY COOLER AIR MASS...BUT HIGHS EXPECTED TO BE DOWN A BIT FROM TODAY /WOULD HAVE LIKELY BEEN A MORE NOTABLE CHANGE IF WE HAD MORE SUN TODAY/...RANGING FROM NEAR 80 IN THE NORTHEAST TO THE MID 80S IN THE SW. .LONG TERM...(FRIDAY NIGHT THROUGH THURSDAY) ISSUED AT 338 PM CDT THU AUG 27 2015 TOP TO BOTTOM...THIS IS THE OVERALL "QUIETEST" LONG TERM FORECAST (DAYS 2-7) THIS FORECASTER HAS WORKED IN A COUPLE MONTHS NOW. OFFICIALLY...ALL 12 OF THESE DAY/NIGHT FORECAST PERIODS CONTINUE CARRYING A DRY FORECAST CWA-WIDE (SEE BELOW FOR POSSIBLE CAVEATS)...AND TEMPERATURES LOOK TO BE QUITE CONSISTENT WITH HIGHS ON MOST DAYS IN THE MID-80S TO LOW-90S RANGE...AND OVERNIGHT LOWS MAINLY SOMEWHERE IN THE 60S...EXCEPT FOR MORE WIDESPREAD COVERAGE OF COOLER 50S RIGHT AWAY FRIDAY NIGHT ESPECIALLY IN NEB ZONES. IN OTHER WORDS...VERSUS NORMALS/AVERAGES...MOST OF THIS TIME FRAME IS LOOKING TO AVERAGE A FEW DEGREES WARMER...BUT CERTAINLY NOTHING ALL THAT UNUSUAL FOR LATE AUGUST/EARLY SEPTEMBER. DIGGING A BIT DEEPER INTO THE PRECIPITATION FORECAST...ALTHOUGH THE FRIDAY NIGHT THROUGH MONDAY DAYTIME FORECAST IS ABOUT AS CLOSE TO "GUARANTEED DRY" AS ONE CAN NORMALLY GET IN THE DAY 2-4 TIME FRAME...PLEASE...PLEASE NOTE THAT LATER FORECASTS MAY ULTIMATELY END UP INSERTING LOW-END SHOWER/THUNDERSTORM CHANCES INTO AT LEAST PARTS OF THE CWA DURING THE MONDAY NIGHT-TUESDAY NIGHT TIME FRAME. THIS WOULD ESPECIALLY BE THE CASE IF THE LATEST GFS SOLUTION MAINTAINS ITSELF FORWARD...WITH A DECENT SIGNAL FOR QPF ESPECIALLY BOTH MONDAY NIGHT AND TUESDAY NIGHT. HOWEVER...AT LEAST FOR NOW THIS SOLUTION LOOKS A BIT "FISHY"/OVERDONE...AND BESIDES...THE LAST FEW ECMWF RUNS HAVE BEEN MORE SPARSE WITH THESE THUNDERSTORM CHANCES. AFTER WEIGHING THE VARIOUS PROS/CONS OF POSSIBLY INTRODUCING LOW-END THUNDERSTORM CHANCES INTO THIS TIME FRAME...HAVE OPTED TO MAINTAIN SOME FORECAST CONSISTENCY FOR NOW BY LEAVING PRECIP CHANCES (POPS) BELOW MENTIONABLE 15 PERCENT LEVELS. BESIDES...FROM A "FORECAST FLIP- FLIP" PERSPECTIVE...YESTERDAY'S DAY SHIFT JUST REMOVED SLIGHT CHANCES FROM TUESDAY...SO WOULD RATHER NOT TOSS THEM BACK IN ONLY 24 HOURS LATER WITHOUT STRONGER MODEL SUPPORT. IN OTHER DEPARTMENTS...HAVE MADE SOME FAIRLY MINOR UPWARD TRENDING TO DAYTIME SOUTHERLY WIND SPEEDS...ESPECIALLY ON SUNDAY...BUT TO THE MON-THURS TIME FRAME AS WELL. IN OTHER WORDS...ALONG WITH THE SEASONABLY WARM TEMPERATURES LOOKS TO COME SEVERAL DAYS OF AT LEAST "BREEZY" CONDITIONS...BUT NOTHING THAT YET APPEARS TO FEATURE WIDESPREAD SUSTAINED SPEEDS OF 20+ MPH. CONSIDERED JOINING NWS OAX TO MY EAST WITH A MENTION OF "PATCHY FOG" FOR LATE FRIDAY NIGHT/EARLY SATURDAY MORNING...BUT GIVEN THIS IS STILL OUT IN THE 3RD-4TH PERIOD...OPTED TO HOLD OFF FOR NOW UNLESS/UNTIL VARIOUS FOG GUIDANCE (INCLUDING SREF PROBABILITY OF VISIBILITY LESS THAN 3 MILES) STARTS SHOWING A STRONGER SIGNAL OF MORE WIDESPREAD FOG POTENTIAL. CERTAINLY SOMETHING FOR UPCOMING SHIFTS TO KEEP AN EYE ON THOUGH. FINISHING UP WITH A LOOK AT SOME DAILY/NIGHTLY DETAIL IN 12-36 HOUR BLOCKS: FRIDAY EVENING/NIGHT: RIGHT AWAY EARLY IN THE EVENING...THE SHORTWAVE TROUGH RESPONSIBLE FOR STORM POTENTIAL DURING THE SHORT TERM WILL BE IN THE PROCESS OF DEPARTING EAST-SOUTHEAST THROUGH IA/IL...WHILE AT THE SURFACE A FAIRLY WELL-DEFINED COLD FRONT WILL EXTEND SOUTHWESTWARD FROM A LOW PRESSURE CENTER OVER IA INTO NORTHEAST/SOUTHERN KS. VARIOUS MODELS SUPPORT THE POSSIBILITY OF EARLY-EVENING CONVECTION POTENTIALLY FLIRTING RATHER CLOSE TO THE SOUTHEAST FRINGES OF THE CWA BEFORE MOVING FARTHER AWAY WITH TIME...BUT BARRING A NOTICEABLE SLOW DOWN OF THE AFOREMENTIONED FRONT...FEEL PRETTY CONFIDENT IN MAINTAINING THE DRY FORECAST CWA- WIDE FOR THE ENTIRE NIGHT. OTHERWISE...BROAD SURFACE HIGH PRESSURE SETTLING IN WILL PROMOTE LIGHT NORTHERLY EVENING BREEZES BECOMING MORE LIGHT/VARIABLE LATE IN THE NIGHT. AS MENTIONED ABOVE...WILL HAVE TO KEEP AN EYE OUT FOR AT LEAST PATCHY FOG POTENTIAL ESPECIALLY IN EASTERN ZONES LATE IN THE NIGHT. AS FOR LOW TEMPS...THIS LOOKS LIKE THE COOLEST NIGHT OF THE LONG TERM...WITH THE MAJORITY OF THE CWA INTO THE UPPER 50S. SATURDAY/SAT NIGHT: RIGHT OFF THE BAT IN THE MORNING...WILL HAVE TO KEEP AN EYE OUT FOR THE AFOREMENTIONED FOG POTENTIAL...BUT HAVE REFRAINED FROM A FORMAL FORECAST MENTION FOR NOW. OTHERWISE...CONFIDENCE REMAINS QUITE HIGH IN A DRY 24 HOURS AS A PRONOUNCED...POSITIVELY-TILTED RIDGE AXIS OVERSPREADS THE PLAINS. HAVE NUDGED UP HIGH TEMPS 1-2 DEGREES MOST AREAS...AIMING FOR A RANGE FROM MID-80S EAST TO NEAR-90 SOUTHWEST. WITH THE SURFACE RIDGE AXIS PASSING THROUGH...BREEZES SATURDAY SHOULD BE THE OVERALL- LIGHTEST OF THE ENTIRE LONG TERM...AVERAGING NO MORE THAN 5-10 MPH FROM VARIABLE DIRECTIONS. SUNDAY/SUNDAY NIGHT: HIGH CONFIDENCE IN THE DRY FORECAST PERSISTS...AS IF NOTHING ELSE THE PROMINENT...POSITIVELY-TILTED MID-UPPER RIDGE AXIS STRENGTHENS EVEN MORE OVER THE LOCAL AREA...KEEPING FORCING FOR CONVECTION LARGELY NON-EXISTENT. COMPARED TO SATURDAY...IT LOOKS TO BE A COUPLE DEGREES WARMER AND CERTAINLY BREEZIER...WITH ESPECIALLY THE WESTERN 1/2 OF THE CWA LOOKING AT SUSTAINED SPEEDS 15-20 MPH WITH HIGHER GUSTS DURING THE AFTERNOON. MONDAY/MONDAY NIGHT: WHILE CONFIDENCE REMAINS RELATIVELY HIGH (ESPECIALLY FOR 4 DAYS OUT) IN A DRY DAY...PER THE EARLIER PRECIPITATION PARAGRAPH...CONFIDENCE STARTS TO WANE AT LEAST A TOUCH MONDAY NIGHT AS THE CENTER OF THE RIDGE AXIS STARTS TO SAG SOUTHEAST OF THE CWA AND ALLOWS POTENTIAL FOR A FEW STORMS TO AT LEAST IMPINGE INTO WESTERN NEBRASKA. WILL KEEP THE CWA DRY FOR NOW...AS THE GFS SOLUTION APPEARS A BIT TOO AGGRESSIVE. TUESDAY/TUESDAY NIGHT: AGAIN...AS ALREADY COVERED ABOVE...KEEPING THESE 24 HOURS VOID OF AT LEAST SLIGHT PRECIP CHANCES MAY BE INCREASINGLY-DIFFICULT GOING FORWARD (ESPECIALLY TUESDAY NIGHT PER THE GFS). STILL THOUGH...AM A BIT SUSPECT THAT MUCH CONVECTION WILL BE ABLE TO DEVELOP...AS EVEN THOUGH THE RIDGE AXIS CONTINUES TO SUPPRESS A BIT...THERE ARE ALSO CERTAINLY NO PROMINENT MID- UPPER FEATURES TO PROMOTE THUNDERSTORM DEVELOPMENT. IN THE END...DECIDED THAT "SILENT" 10 POPS ARE THE BEST ROUTE FOR NOW UNTIL IT DRAWS NEARER. WEDNESDAY DAYTIME-THURSDAY DAYTIME: ALTHOUGH CERTAINLY CANNOT "GUARANTEE" THAT THESE LAST 36 HOURS MAINTAIN A DRY FORECAST ALL THE WAY THROUGH...THIS IS FAR ENOUGH OUT IN TIME THAT DIDN'T EVEN CONSIDER "RUINING" THE GOING DRY FORECAST YET. IN THE MID- UPPER LEVELS...THE ECMWF/GFS ARE IN PRETTY GOOD AGREEMENT THAT THE LOCAL REGION ONLY SEES LIMITED FORCING ALONG THE VERY SOUTHEAST FRINGES OF STRONGER FLOW ASSOCIATED WITH A LARGER-SCALE TROUGH STILL CENTERED WELL TO THE NORTHWEST OVER THE PACIFIC NORTHWEST REGION. && .AVIATION...(FOR THE 00Z KGRI/KEAR TAFS THROUGH 00Z FRIDAY EVENING) ISSUED AT 657 PM CDT THU AUG 27 2015 COULD HAVE SOME SEVERE STORMS AROUND AS A SURFACE LOW TRACKS EAST THIS EVENING.
