What happened

The episode as NWS GID wrote it up.

During the pre-dawn hours on this Wednesday morning, a cluster of strong elevated thunderstorms flared up across Southwest Nebraska and Northwest Kansas in an area of mid level convergence. These storms eventually formed into a more solid north-south oriented line and started to march east across South Central Nebraska. Shortly after sunrise, the southern end of the line strengthened and formed into a small bow echo, likely becoming at least partially surface-based in a mesoscale environmnent featuring around 1500 J/kg most-unstable CAPE, and 40 knots of deep-layer vertical wind shear. Thayer County was hardest-hit in South Central Nebraska, with reports including estimated wind gusts to 60 MPH near Carleton, and half dollar size hail near Hebron.

What forecasters said that day

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 Hastings, NE wrote its last area forecast discussion before the first event at Sep 1, 7:29 AM CST, 25 minutes earlier.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
829 AM CDT WED SEP 1 2010

.UPDATE...ONGOING CONVECTION CONTINUES PUSHING ACROSS THE CWA THIS
MORNING...WITH THE STRONGEST ACTIVITY EXISTING NEAR THE HIGHWAY
136 CORRIDOR. UPDATED GRIDS TO REFLECT CURRENT TRENDS.

&&

.PREV DISCUSSION... /ISSUED 622 AM CDT WED SEP 1 2010/

AVIATION...12Z TAF. MANY CHALLENGES CONTINUE FOR THIS FORECAST
INCLUDING THE CHANCES OF THUNDERSTORMS AND IFR CEILINGS. KUEX WSR-
88D SHOWS AN AREA OF THUNDERSTORMS TRACKING EAST ACROSS SOUTH
CENTRAL NEBRASKA EARLY THIS MORNING. AN UPPER LEVEL DISTURBANCE IS
HELPING KEEP THE STORMS GOING THIS MORNING...AND AT THEIR CURRENT
MOVEMENT...THEY WOULD JUST GLANCE KGRI. WILL CARRY A TEMPO GROUP
FOR SHOWERS AS A START WITH CB IN THE CLOUD GROUP TO SUGGEST THAT
THUNDERSTORMS WILL BE NEARBY. ANOTHER CONCERN THIS MORNING IS THE
POTENTIAL FOR IFR CEILINGS WITH A FEW LOCATIONS ACROSS SOUTH
CENTRAL NEBRASKA REPORTING CEILINGS OF 800-900FT. KGRI CURRENTLY
HAS A CEILING AROUND 1100FT...BUT 06Z NAM BUFR SOUNDINGS SUGGEST
THOSE SHOULD LOWER TO IFR LEVELS IN THE NEXT HOUR OR TWO. WILL
CARRY THE IFR CEILING FROM THE START IN THE TAF...AND LIFT THEM TO
MVFR AROUND 16Z WHICH FALLS IN LINE WITH THE 06Z NAM BUFR
SOUNDINGS. VFR CONDITIONS COULD RETURN BY EARLY AFTERNOON...AND
WILL GO WITH THAT GENERAL SCENARIO. THE CHANCES OF THUNDERSTORMS
BEYOND THIS MORNING ARE UNCERTAIN WITH MANY DIFFERENT SOLUTIONS
BEING SHOWN BY SHORT TERM FORECAST MODELS. DECIDED TO LEAN ON THE
00Z NCEP 4KM WRF-NMM FOR THIS FORECAST SINCE IT SEEMS TO BE
HANDLING THE ONGOING CONVECTION. THIS WILL BRING ANOTHER CHANCE OF
THUNDERSTORMS TO KGRI LATE THIS EVENING...BUT AGAIN CONFIDENCE IN
ANY PARTICULAR SOLUTION IS NOT VERY HIGH.

PREV DISCUSSION... /ISSUED 423 AM CDT WED SEP 1 2010/

DISCUSSION...PRECIPITATION CHANCES THROUGH TONIGHT PRESENT THE
MAIN CHALLENGE.

REGIONAL RADAR IMAGERY FROM EARLY THIS MORNING SHOWS A CLUSTER OF
SHOWERS AND THUNDERSTORMS APPROACHING THE WESTERN CWA. THIS BATCH
OF ELEVATED CONVECTION INITIALLY FIRED ALONG THE NORTHERN CO FRONT
RANGE...AND IS BEING DRIVEN BY A MID-LEVEL PERTURBATION IN
COMBINATION WITH INCREASING H85 THETA-E ADVECTION AND ISENTROPIC
LIFT IN LOW-LEVEL UPSLOPE FLOW NORTH OF THE THE SURFACE AND H85
FRONTS. GIVEN THESE FACTORS...THE CONVECTION SHOULD SUSTAIN
ITSELF AS IT WORKS EAST/NORTHEAST AND HAVE INCREASED POPS
ACCORDINGLY FOR THIS MORNING. LAPS AND RUC ANALYSIS DATA SHOW
MUCAPES OF LESS THAN 500 J/KG WHERE THE CONVECTION CURRENTLY IS
AND WILL BE WORKING INTO...SO NOT EXPECTING ANY SEVERE WEATHER
WITH THESE MORNING STORMS. THE SURFACE COLD FRONT HAS PUSHED SOUTH
OF THE CWA WHILE THE H85 FRONT REMAINS NEAR THE FAR SOUTHEAST CWA
BORDER. HAVE HAD SOME ISOLATED CONVECTION AT TIMES IN THE CONVERGENT
AXIS ALONG THE ELEVATED FRONT...AND CANNOT RULE OUT THE
POSSIBILITY OF SOME ADDITIONAL ISOLATED CELLS POPPING UP. SURFACE
DEWPOINTS HAVE DIPPED INTO THE LOWER 50S TO LOWER 60S NORTH OF THE
FRONT WHILE TEMPS HAVE FALLEN INTO THE MID 50S NORTH TO UPPER 60S
SOUTH IN THE DRIER POST-FRONTAL AIRMASS.

FOR TODAY AND TONIGHT...THERE REALLY COULD BE OFF AND ON SCATTERED
STORMS AROUND THROUGH MUCH OF THE PERIOD. SURFACE CYCLOGENESIS
WILL OCCUR OVER THE DAKOTAS TODAY AHEAD OF MID/UPPER TROUGH
LIFTING ACROSS THE NORTHERN ROCKIES. THIS DEEPENING SURFACE LOW
OVER THE DAKOTAS...COMBINED WITH THE EASTWARD MOVEMENT OF ANOTHER
SURFACE LOW ALONG THE KS/OK BORDER WILL HELP THE FRONT CURRENTLY
TO OUR SOUTH TO LIFT BACK NORTH AS A WARM FRONT. LOW-LEVEL
MOISTURE AND INSTABILITY WILL INCREASE ACCORDINGLY...ALTHOUGH
DEGREE OF INSTABILITY THAT DEVELOPS THIS AFTERNOON IS STILL
UNCERTAIN DUE TO PRESENCE OF MORNING PRECIPITATION AND CLOUD
COVER. OBVIOUSLY AMOUNT OF CLOUD COVER WILL LARGELY IMPACT
AFTERNOON INSTABILITY...BUT THE CONVECTION MAY ALSO IMPEDE THE
NORTHWARD MOISTURE RETURN TO SOME DEGREE AS WELL.
NONETHELESS...MODELS REMAIN CONSISTENT IN ADVECTING LOWER 60 TO
POSSIBLY LOWER 70 F SURFACE DEWPOINTS AND H85 DEWPOINTS IN THE MID
TEENS C BACK NORTHWARD INTO THE CWA...WHICH COMBINED WITH COOLER
TEMPS ALOFT/STEEPENING MID-LEVEL LAPSE RATES AS THE MID/UPPER
TROUGH SLIDES IN...WILL YIELD 0-1KM MLCAPES IN THE 1500-2500 J/KG
RANGE ASSUMING WE SEE AT LEAST SOME BREAKS IN THE CLOUD COVER.
DEEP LAYER SHEAR IS THE STRONGEST WE/VE SEEN IN QUITE SOME
TIME...AVERAGING 40-50 KTS. THUS CONDITIONS WILL BE SUPPORTIVE OF
SEVERE WEATHER...INCLUDING SUPERCELLS...WITH ANY STORMS THAT DO
DEVELOP THIS AFTERNOON AND EVENING. THAT BEING SAID...COVERAGE OF
STORMS IS STILL SOMEWHAT DIFFICULT TO PIN DOWN. HOWEVER...THINK
PERSISTENT ISENTROPIC LIFT IN THE 305-315K LAYER ALONG WITH
INCREASING MID/UPPER DYNAMIC FORCING AS THE TROUGH AXIS
APPROACHES LATER TODAY SHOULD SUPPORT SCATTERED THUNDERSTORM
DEVELOPMENT AND WILL KEEP POPS IN THE CHANCE/SCATTERED RANGE.
WATER VAPOR IMAGERY ALSO SHOWS SEVERAL SUBTLE MID-LEVEL
PERTURBATIONS THAT COULD ALSO ASSIST THUNDERSTORM DEVELOPMENT.
PRECIPITABLE WATERS REMAIN IN THE 1-2 INCH RANGE...SO COULD ALSO
SEE SOME LOCALLY HEAVY RAIN WITH THESE STORMS. AS FAR AS TEMPS
GO...WILL AIM FOR HIGHS IN THE LOWER 80S MOST SPOTS WITH A FEW MID
80S SOUTH...ALTHOUGH ADMITTEDLY CLOUDS/PRECIP MAY PLAY HAVOC WITH
THESE.

A STRONG COLD FRONT REMAINS ON SCHEDULE TO PUSH THROUGH LATE
TONIGHT INTO EARLY THURSDAY MORNING AS A STRONG UPPER JET/WAVE
CURRENTLY OVER THE PAC NW/BC CONTINUE TO DIVE EAST/SOUTHEAST...
EVENTUALLY CROSSING THE NORTHERN PLAINS TONIGHT. THUNDERSTORMS
WILL REMAIN POSSIBLE OVERNIGHT AS THE FRONT SWEEPS THROUGH AND THE
FORECAST AREA REMAINS ON THE SOUTHERN FRINGE OF MID/UPPER FORCING.
MAY SEE A SHOWER OR STORM LINGER ACROSS THE SOUTHEAST INTO EARLY
THURSDAY MORNING...HOWEVER MUCH COOLER/DRIER/MORE STABLE AIR WILL
QUICKLY SPILL IN BEHIND THE FRONT AS SURFACE HIGH PRESSURE
OVERTAKES THE AREA. WILL SEE CLEARING SKIES THURSDAY AS A
RESULT...AND THE FEEL OF FALL WILL DEFINITELY BE IN THE AIR.
NORTHWEST WINDS WILL BE GUSTY IN THE STRONG GRADIENT AS THE
SURFACE HIGH BUILDS IN...LIKELY GUSTING TO AROUND 35 MPH...BUT
WILL BEGIN TO DIE DOWN BY LATE AFTERNOON AS THE HIGH SETTLES
IN. MID TO UPPER 70S ARE FORECAST ON THURSDAY...WITH LOWS DROPPING
INTO THE 40S THURSDAY NIGHT IN THE DRY AIRMASS. FRIDAY HAS THE
LOOK OF A BEAUTIFUL FALL DAY WITH HIGHS IN THE MID TO UPPER
70S...FAIRLY LIGHT WINDS WITH THE SURFACE HIGH OVERHEAD...AND
AMPLE SUNSHINE UNDER STRONG SUBSIDENCE.

THE SURFACE HIGH SHIFTS EAST ON SATURDAY AND TEMPS WILL BEGIN TO
MODERATE IN THE RETURN FLOW. THIS WARMING TREND WILL CONTINUE INTO
LABOR DAY...AS WILL DRY CONDITIONS AS AN UPPER RIDGE PROPAGATES
EAST ACROSS THE REGION. HOWEVER...PRECIP CHANCES COULD RETURN BY
MONDAY NIGHT AS A COLD FRONT PUSHES THROUGH.
