The radar

The Grand Island radar (KUEX), 87 km from the middle of the area, began a volume at 05:39 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

N. Platte/Lee Bi, NE (KLBF), launched 00:00Z, 5.6 hours before the alert went out and 120 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

What 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 Hastings, NE wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 26, 8:49 PM CDT, 3 hours 46 minutes earlier.

Area forecast discussion, Jul 26, 8:49 PM CDT, 3 hours 46 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE HASTINGS NE
849 PM CDT TUE JUL 26 2011

.UPDATE...EXPIRED HEAT ADVISORY THAT WAS ISSUED FOR TODAY AS
TEMPERATURES HAVE FALLEN OFF AS EXPECTED THIS EVENING. CHANCE OF
THUNDERSTORMS TONIGHT CONTINUES TO LOOK ON TRACK FOR NORTHERN
ZONES ESPECIALLY ALONG AND NORTH OF INTERSTATE 80.

&&

.PREV DISCUSSION... /ISSUED 659 PM CDT TUE JUL 26 2011/

AVIATION...00Z TAF. THE PRIMARY CONCERN WILL CENTER ON
PRECIPITATION CHANCES AFTER MIDNIGHT. EXPECT CLEAR TO MOSTLY CLEAR
SKIES WILL PERSIST THROUGH THE EVENING. A FRONTAL BOUNDARY WILL
THEN APPROACH KGRI IN THE PREDAWN EARLY MORNING HOURS. A LINE OF
THUNDERSTORMS OVER THE SANDHILLS THIS AFTERNOON SHOULD HOLD
TOGETHER AS THEY TRACK EAST ACROSS NORTH CENTRAL NEBRASKA TONIGHT.
HOWEVER...THE SOUTHERN EXTENT OF THIS LINE BECOMES MORE
QUESTIONABLE AS YOU GET AS FAR SOUTH AS KGRI. VFR CEILINGS AND
VISIBILITIES ARE EXPECTED DESPITE THE POSSIBILITY OF
THUNDERSTORMS.

PREV DISCUSSION... /ISSUED 446 PM CDT TUE JUL 26 2011/

SHORT TERM...TONIGHT THROUGH 12Z THURSDAY.  PRIMARY FORECAST
CONCERNS LIE WITH THUNDERSTORM CHANCES...AND HOT TEMPERATURES FOR
A PORTION OF THE CWA ON WEDNESDAY.

UPPER AIR AND SATELLITE DATA CONTINUES TO SHOW THE REGION UNDER THE
INFLUENCE OF A RIDGE CENTERED IN THE SOUTHERN PLAINS...WITH
GENERALLY ZONAL/SOUTHWESTERLY FLOW ACROSS THE CWA.  A LACK OF
NOTABLE DISTURBANCES MOVING THROUGH THE REGION...AND WARM MID LEVEL
TEMPERATURES /13-15C AT 700MB/ KEEPING THINGS CAPPED OFF...HAVE LEAD
TO A QUIET AFTERNOON WITH MOSTLY CLEAR SKIES.  AT THE
SURFACE...LITTLE HAS CHANGED THROUGH THE DAY...WITH A LARGE AREA OF
HIGH PRESSURE CENTERED OVER THE WRN GREAT LAKES AND EXTENDING SOUTH
TOWARD THE GULF REGION...AND A TROUGH OF LOW PRESSURE ALONG THE HIGH
PLAINS...WITH THE MAIN WARM FRONTAL BOUNDARY WELL TO THE NORTH OF
THE CWA.

EXPECTING A QUIET EVENING FOR THE CWA...THOUGH PRECIPITATION CHANCES
WILL BE INCREASING THE CLOSER WE GET TOWARD MIDNIGHT.  THUNDERSTORM
ACTIVITY IS EXPECTED TO DEVELOP/INCREASE IN COVERAGE ALONG THE SFC
TROUGH TO THE WEST OF THE CWA AS A WEAK MID LEVEL DISTURBANCE MOVES
ONTO THE PLAINS. THIS ACTIVITY IS EXPECTED TO EVOLVE INTO A
MCS...WHICH WILL MOVE EAST ACROSS THE REGION...AIDED BY AN
INCREASING SOUTHERLY LOW LEVEL JET NOSING IN FROM THE SOUTH.
INCREASED POPS A BIT FOR THE OVERNIGHT HOURS...BUT DID KEEP THE POPS
CONFINED TO OUR SC NEB COUNTIES...WITH MODELS IN PRETTY GOOD
AGREEMENT SHOWING THE ACTIVITY PUSHING A BIT MORE NORTHEAST AS THE
LLJ INCREASES AND PUSHES FURTHER NORTH...AND WARM MID LEVEL
TEMPERATURES KEEP A GOOD CHUNK OF THE CWA CAPPED OFF. CANT
COMPLETELY RULE OUT THAT AN ISOLATED THUNDERSTORM COULD END UP ON
THE SEVERE SIDE...SO DID THROW THAT MENTION INTO THE HWO.

LOOKING TOWARD WEDNESDAY...KEPT THE MORNING HOURS DRY IN THE WAKE OF
TONIGHTS ACTIVITY...CONTINUES TO BE GOOD AGREEMENT AMONG MODELS THAT
THINGS WILL SHIFT E/NE OF THE BY SUNRISE.  MAIN CONCERN TURNS TO THE
FRONTAL BOUNDARY...AND WHERE IT ULTIMATELY ENDS UP ACROSS THE CWA.
UPPER LEVEL FLOW BECOMES MORE ZONAL ACROSS THE REGION...AND WITH THE
MAIN DISTURBANCE SHIFTING OFF TO THE EAST EARLY IN THE DAY...THE
FRONTAL BOUNDARY LOSES ITS PUSH AND STALLS OUT. THIS FRONTAL
BOUNDARY LOOKS TO PROVIDE A FOCUS FOR THUNDERSTORM DEVELOPMENT AS
ANOTHER MID LEVEL WAVE MOVES INTO THE REGION...BUT SOME QUESTION
REMAINS ON IF/WHEN THINGS WILL FIRE DUE TO ANOTHER DAY WITH WARM MID
LEVEL TEMPERATURES KEEPING THINGS CAPPED OFF.  DECIDED TO INSERT
SOME LOW POPS ACROSS THE SOUTH DURING THE LATE AFTERNOON...AND
RAISED POPS A BIT DURING THE EVENING/OVERNIGHT HOURS /ESP IN THE
SOUTH/...WITH THE LLJ EXPECTED TO RAMP UP ONCE AGAIN.  WILL BE THE
POTENTIAL AGAIN FOR ANY THUNDERSTORMS THAT DEVELOP TO BE ON THE
STRONG/SEVERE SIDE...AND MOST OF THE CWA IS IN A SLGT RISK IN THE
DAY 2 OUTLOOK.

ANOTHER CONCERN FOR WEDNESDAY AFTERNOON...WHICH IS ALSO DEPENDENT ON
THE EVENTUAL FRONTAL BOUNDARY...IS TEMPERATURES.  WITH THE FRONT
EXPECTED TO END UP NEAR THE STATE LINE DURING THE AFTERNOON HOURS
AND MORE N/NERLY WINDS BUILDING IN BEHIND...LOWER TEMPS A TOUCH INTO
THE LOWER 90S.  FURTHER SOUTH...ESP AHEAD OF THE FRONT...INCREASED
MIXING WITH MORE SOUTHERLY FLOW SHOULD ALLOW TEMPERATURES TO WARM UP
NEAR/ABOVE THE 100 DEGREE MARK.  WHILE THE BETTER DEWPOINTS/HIGHER
RH VALUES WILL BE ACROSS THE NORTHER HALF OF THE CWA...POTENTIAL
EXISTS FOR SOME LOCATIONS TO SEE HEAT INDEX VALUES NEAR 105...AND
DECIDED TO HOIST A HEAT ADVISORY FOR THE FAR SOUTHEASTERN 5 COUNTIES
OF THE CWA.  MID SHIFT WILL HAVE TO DETERMINE WHETHER MORE COUNTIES
NEED TO BE ADDED...ESPECIALLY IF MODELS START TO TREND THE FRONT
ENDING UP A BIT FURTHER NORTH.

LONG TERM...12Z THURSDAY THROUGH TUESDAY. PRIMARY CONCERN IN THE
EXTENDED PERIODS ARE THUNDERSTORM CHANCES IN THE THURSDAY THROUGH
SATURDAY TIME FRAME. AS FOR HEAT...ALTHOUGH TEMPERATURES WILL
CONTINUE TO AVERAGE ABOVE NORMAL THROUGH THE PERIOD...AND A FEW
SPOTS MAINLY FAR SOUTHEAST COULD OCCASIONALLY REACH HEAT INDEX
READINGS OF 105...THERE ARE CURRENTLY NO DAYS THAT TRULY STAND OUT
AS NEEDING MULTIPLE-COUNTY HEAT ADVISORIES OR WARNINGS.

IN A LOT OF WAYS...THE OVERALL SYNOPTIC PATTERN THROUGH THE PERIOD
REMAINS MUCH THE SAME AS RECENT WEEKS...AND IS VERY TYPICAL OF
MID-SUMMER. LEANING TOWARD THE 12Z ECMWF SOLUTION...WHICH OVERALL
IS IN DECENT AGREEMENT WITH THE GFS AS WELL...THE CWA GENERALLY
REMAINS ALONG THE INTERFACE BETWEEN THE EXPANSIVE SUBTROPICAL
RIDGE DOMINATING THE SOUTHERN CONUS...AND THE FASTER MID/UPPER
FLOW FOCUSED ACROSS THE NORTHERN 1/4 OF THE NATION. FROM TIME TO
TIME...THE MID/UPPER RIDGE EXPANDS NORTHWARD OVER THE CENTRAL
PLAINS...CAUSING ANY EFFECTIVE SURFACE QUASI-STATIONARY OR WARM
FRONT TO SURGE NORTHWARD AND LIKELY TURNING OFF THUNDERSTORM
CHANCES. ON THE OTHER HAND...A SERIES OF RATHER VIGOROUS SHORTWAVE
TROUGHS SKIRTING THE INTERNATIONAL BORDER ACROSS SOUTHERN CANADA
WILL OCCASIONALLY FLATTEN THE RIDGE...MAKING THE CWA MORE PRONE TO
SUBTLE...WEAK MID LEVEL DISTURBANCES...AND ALSO PROMOTING
THE EFFECTIVE EAST-WEST OR NORTHWEST-SOUTHEAST ORIENTED SURFACE
FRONT TO SET UP NEAR...OR WITHIN THE CWA.

TAKING THIS GENERAL PICTURE AND APPLYING A FEW DETAILS...KEPT
THUNDERSTORM MENTION INTACT CWA-WIDE DURING THE THURSDAY-SATURDAY
TIME FRAME FROM PREVIOUS FORECAST. ALTHOUGH KEPT CHANCES AT ONLY
20 PERCENT FRIDAY-SATURDAY...THURSDAY INTO THURS NIGHT LOOK TO
HAVE BETTER POTENTIAL AS THE SURFACE FRONT STALLS OUT OVER THE
AREA AND MID LEVEL CAPPING IS WEAKEST IN THE PRESENCE OF THETA-E
ADVECTION ON THE NOSE OF A MODEST LOW LEVEL JET. UPPED POPS TO 40
PERCENT ACROSS ROUGHLY THE SOUTHERN HALF OF THE CWA THURS
NIGHT...AND GIVEN THE SUGGESTION OF SEVERAL MODELS WITH FAIRLY
WIDESPREAD CONVECTION DURING THIS TIME...FUTURE INCREASES ARE VERY
POSSIBLE. IN FACT...12-HR SREF POPS ACTUALLY ADVERTISE 70-80
PERCENT CHANCES ACROSS THE SOUTH FOR THE THURS NIGHT PERIOD...BUT
NOT JUMPING ON BOARD THAT HIGH YET FOR SURE. SPC DAY 3 SLIGHT RISK
FOR THE ENTIRE CWA IS HARD TO ARGUE WITH...AS ITS THE SAME STORY
WITH ONLY MODEST 20-30KT DEEP LAYER SHEAR...BUT HIGH CAPE VALUES
AND PRECIPITABLE WATER. ORGANIZED MULTICELL STORMS CERTAINLY A
GOOD BET...WITH LOCALLY HEAVY RAINFALL OF 1-2 INCH POTENTIAL
THERE.

ALTHOUGH STORM CHANCES FOR FRIDAY INTO SATURDAY DO NOT LOOK AS
FOCUSED...WAS UNWILLING TO PULL 20 POPS YET GIVEN THAT THE SURFACE
FRONT SHOULD ONLY SLOWLY MOVE BACK NORTH. MAINTAINED DRY FORECAST
SATURDAY NIGHT THROUGH TUESDAY. INITIALLY...MID/UPPER RIDGE BUILDS
NORTHWARD OVER THE AREA AND SURFACE FRONT HEADS NORTH...AND ALTHOUGH
THIS SHOULD HELP CAP OFF THINGS...WOULD STILL NOT BE SHOCKED TO
SEE ISOLATED CONVECTION POP IN AREAS OF HIGH INSTABILITY EVEN
DURING THE CURRENTLY ADVERTISED DRY PERIODS. DRY FORECAST COMES A
BIT MORE INTO QUESTION BY MON NIGHT INTO TUESDAY AS THE NEXT
SURFACE FRONT IS ADVERTISED TO ENTER THE AREA...BUT WITH THIS
BEING DAY 7 WILL HOLD OFF ON INTRODUCING POPS UNTIL BETTER
CONTINUITY ARRIVES.

FINALLY TURNING TO TEMPERATURE TRENDS...NO PARTICULARLY COOL OR
CONVERSELY BLAZING HOT DAYS IN STORE...WITH MOST DAYS TOPPING OUT
IN THE UPPER 80-MID 90S IN NEB ZONES...AND MID 90S-SLIGHTLY OVER
100 IN KS ZONES. OVERALL HOTTEST DAYS LOOK TO BE SUNDAY-MONDAY AS
THE UPPER RIDGE BECOMES MOST DOMINANT AND THEN STARTS SHUNTING
SOUTH AHEAD OF THE APPROACHING SURFACE BOUNDARY.
