What happened

The episode as NWS GID wrote it up.

Severe thunderstorms produced a widespread area of large hail and high winds from Gosper County to Sherman County. Some of the worst damage was along the Dawson and Gosper counties line. In this area, the combination of 40 to 60 mph winds and hail to the size of golf balls battered crops. There were several reports of tree limbs down around the lake and in the town of Elwood. The crow's nest (i.e. announcer's booth) at the Elwood football field was blown apart by the wind. Though not as prolific, the hail was generally bigger to the northeast in northwest Buffalo County, and in Sherman County about halfway between Rockville and Loup City, where baseball size hail was reported on Highway 58.

What forecasters said that day

Area forecast discussion, Aug 21, 1:59 PM CST, 2 hours 46 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
259 PM CDT TUE AUG 21 2007

.SHORT TERM...THIS EVENING THROUGH WEDNESDAY NIGHT. THE FORECAST
CHALLENGE THROUGH THE PERIOD WILL ONCE AGAIN CENTER ON
THUNDERSTORMS... SOME POSSIBLY SEVERE.

ATMOSPHERE IS BEGINNING TO DESTABILIZE WITH STRONG AFTERNOON
HEATING. EARLY AFTERNOON TEMPERATURES ARE BACK INTO THE 90S AND A
CUMULUS FIELD IS NOW FORMING ACROSS OUR NORTHWESTERN CWA. MID LEVEL
CAP IS STRONGER TODAY THAN YESTERDAY BUT STILL EXPECT CONVECTION TO
EVENTUALLY OVERCOME CAPPING...WHICH SHOULD FIRST OCCUR ACROSS
NORTHERN AND WESTERN ZONES WITHIN THE NEXT FEW HOURS. BULK OF UPPER
LEVEL ENERGY ASSOCIATED WITH UPPER TROUGH ACROSS THE NORTHERN PLAINS
WILL INTERACT WITH STRONG INSTABILITY AND WEAK SFC BOUNDARY ACROSS
PORTIONS OF OUR CWA TO INITIATE CONVECTION. CONVECTION WILL THEN
SPREAD EAST AND PERHAPS A BIT SOUTHEAST DURING THE EVENING HOURS.
OPERATIONAL FORECAST MODELS AND ENSEMBLES ARE IN FAIRLY GOOD
AGREEMENT WITH THIS SET UP...WHICH PUTS THE GREATEST THREAT FOR
THUNDERSTORMS ACROSS THE NORTHWESTERN TWO THIRDS OF OUR CWA. ML CAPE
VALUES WILL ONCE AGAIN CLIMB OVER 5000 J/KG THIS AFTERNOON. 0 TO 6KM
VERTICAL SHEAR VALUES WILL BE SLIGHTLY LOWER THAN YESTERDAY...BUT
STILL RESPECTABLE ESPECIALLY ACROSS THE NORTH AT 30 TO 35KT.
COMBINATION OF SHEAR...INSTABILITY...ALONG WITH AT LEAST SOME
DYNAMICS WILL MAKE SEVERE WEATHER LIKELY ACROSS PORTIONS OF OUR CWA
LATER THIS AFTERNOON INTO THIS EVENING.

OVERNIGHT CONVECTION WILL FORCE FRONTAL BOUNDARY BACK TOWARDS THE
SOUTH FURTHER INTO THE HEART OF OUR CWA BY LATE TONIGHT INTO
TOMORROW. THIS WILL ACT TO COOL TEMPERATURES DOWN BY A FEW DEGREES
TOMORROW ACROSS THE NORTH...WHILE PROVIDING A CONTINUING FORCING
MECHANISM FOR STRONG TO SEVERE THUNDERSTORMS ONCE AGAIN TOMORROW
AFTERNOON AND EVENING.

.LONG TERM...12Z THURSDAY THROUGH TUESDAY. MAIN FOCUS IS ON
CONTINUED THUNDERSTORM CHANCES THROUGH FRIDAY.

AN ACTIVE PATTERN LOOKS TO CONTINUE THROUGH FRIDAY. A STALLED
SURFACE FRONT REMAINS DRAPED ACROSS THE REGION ON THURSDAY...WITH AN
UPPER TROUGH TO THE WEST OVER THE WESTERN CONUS. MODELS ARE IN
AGREEMENT IN EJECTING SHORTWAVE ENERGY FROM THE TROUGH EASTWARD
ACROSS THE AREA BUT DIFFER WITH RESPECT TO TIMING OF THIS. PLENTY OF
MOISTURE/INSTABILITY WILL BE IN PLACE ACROSS THE AREA TO SUPPORT
STRONG CONVECTION...PARTICULARLY ACROSS SOUTHERN PORTIONS OF THE
CWFA SOUTH OF THE SURFACE BOUNDARY. OF COURSE ACTUAL BOUNDARY
PLACEMENT WILL DEPEND ON INFLUENCE OF CONVECTIVE OUTFLOWS/INFLUENCES
THE NEXT COUPLE OF DAYS...SO EXACT PLACEMENT BY THURSDAY REMAINS IN
QUESTION. THE BETTER PRECIP CHANCES HOLD OFF UNTIL THURSDAY NIGHT
WHEN BETTER UPPER FORCING COMES AS THE RIGHT ENTRANCE REGION OF AN UPPER
JET STREAK MOVES ACROSS THE CWFA AND THE LLJ INCREASES TO AROUND
40 KTS. THUS ANOTHER MCS THURSDAY NIGHT LOOKS LIKE A GOOD BET AT
THIS POINT...AND THIS ADDITIONAL RAINFALL ON TOP OF THAT EXPECTED
OVER THE NEXT COUPLE OF DAYS COULD POSE SOME HYDRO ISSUES. THE
MAIN UPPER TROUGH PUSHES ACROSS THE PLAINS ON FRIDAY...PROVIDING
THE LAST REAL SHOT OF PRECIP FOR THIS STRING OF POTENTIALLY WET
DAYS. THE UPPER TROUGH WILL PUSH THE STALLED SURFACE BOUNDARY
SUFFICIENTLY FAR SOUTH OF THE FORECAST AREA BY SATURDAY TO SHUNT
RAIN CHANCES SOUTH OF THE AREA.

COOLER TEMPERATURES ARE IN STORE FOR THE THURSDAY THROUGH SATURDAY
PERIOD...BUT DEGREE OF COOL DOWN IS TRICKY. COULD SEE A PRETTY GOOD
NORTH TO SOUTH GRADIENT ACROSS THE REGION ON THURSDAY DUE TO FRONTAL
POSITION...AND CURRENTLY HAVE ABOUT A 10 DEGREE SPREAD. SATURDAY
LOOKS LIKE THE PICK DAY OF THE WEEK AS PRECIP PUSHES SOUTH AND DRIER
AIR SPREADS IN BEHIND THE FRONT. EAST TO SOUTHEAST SURFACE WINDS AND
H85 TEMPS IN THE UPPER TEENS SHOULD HOLD TEMPS IN THE 80S FOR HIGHS.
A WARMING TREND THEN BEGINS ON SUNDAY AS THE LEE TROUGH DEEPENS AND
SURFACE HIGH PUSHES EASTWARD...RESULTING IN INCREASING SOUTHERLY
WINDS AND WAA. TEMPS CONTINUE TO WARM MONDAY INTO TUESDAY UNDER THE
INFLUENCE OF SOUTHWEST FLOW ALOFT AND SOUTHERLY FLOW AT LOW
LEVELS...WHICH WILL ALSO BRING MOISTURE BACK NORTHWARD. THE NEXT
CHANCE FOR ORGANIZED PRECIP COMES TUESDAY OR TUESDAY NIGHT AS AN UPPER
TROUGH TRACKING ACROSS SOUTHERN CANADA AND THE NORTHERN TIER
STATES SENDS A COLD FRONT SOUTH. HAVE HELD OFF ON POPS UNTIL
TUESDAY NIGHT AS ENSEMBLE DATA SUPPORTS A SLOWER SOLUTION THAN
OPERATIONAL GFS RUNS...WITH HPC GUIDANCE SUPPORTING A SLOWER
SOLUTION AS WELL.

&&

.AVIATION...18Z TAF. HOT AND MUGGY VFR CONDITIONS EXPECTED EARLY
THROUGH MID AFTERNOON WITH SOUTHERLY FLOW AT KGRI. THUNDERSTORMS
WILL THEN FORM TO THE NORTH AND WEST OF KGRI BY LATE AFTERNOON
WITH THE BEST CHANCE OF THUNDERSTORMS AT KGRI AFTER 6PM AND
ESPECIALLY LATER ON THIS EVENING. THUNDERSTORMS COULD BE STRONG TO
SEVERE AND WILL LIKELY SEND OUTFLOW BOUNDARIES THROUGH THE AREA
DURING THE EVENING HOURS. VISIBILITY AND CEILING HEIGHTS CAN BE
EXPECTED TO FALL DURING THUNDERSTORMS BUT OTHERWISE SHOULD BE IN
THE VFR RANGE.

.GID WATCHES/WARNINGS/ADVISORIES...
