The radar

The Grand Island radar (KUEX), 83 km from the middle of the area, began a volume at 23:56 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 tornado 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 12:00Z, 11.9 hours before the alert went out and 153 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 tornado 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 tornado warning went out at May 10, 3:23 PM CDT, 3 hours 29 minutes earlier.

Area forecast discussion, May 10, 3:23 PM CDT, 3 hours 29 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
323 PM CDT TUE MAY 10 2005

.SHORT TERM...LATE AFTERNOON AND TONIGHT. UPPER LOW SITTING ON
PACIFIC COAST WITH SHORT WAVE RIDGE OVER CENTRAL U.S. WATER VAPOR
IMAGERY HAS THIS PATTERN SLOW TO MOVE WITH JET DIGGING IN BEHIND SO
WE SIT IN SW FLOW. BIG STORY IS THE SURFACE WARM FRONT WHICH HAS
BEEN LIFTING EVER SO SLOWLY ACROSS THE CWA DURING THE DAY. IT WAS
SOUTH OF THE NE/KS STATE LINE AT 12Z BUT HAS MOVED NORTH OF LXN AND
GRI AS OF 18Z. APPEARS IT WILL BE SOMEWHERE IN OUR NORTHERN CWA
AROUND CONVECTIVE INITITIATION TIME WHICH APPEARS TO BE ABOUT 21Z.
PARAMETERS LOOK GOOD AS ETA CAPE TO BE APPROX 4000 J/KG NEAR THE
FRONT WHILE LCL IS AROUND 1000-1200M.  SHEAR VALUES FROM SPC MESO
PAGE SHOWING VERY HIGH 0-3 SR HELICITY WHICH ARE VALIDATED FOR
NORTHEAST NEBRASKA BY NELEIGH PROFILER WHICH HAD 462 0-3 KM SRH AT
18Z. FORECAST SOUNDINGS SHOWING SOUTHERN HALF OF CWA SHOULD REMAIN
CAPPED IN THE WARM SECTOR. GUT FEELING IS THAT EARLIER SHIFT WAS
RIGHT ON WITH LIMITING THUNDERSTORMS TO AREAS NORTH OF HIGHWAY 92.
HOWEVER...DECIDED TO THROW IN A LITTLE CAUTION AND EXTEND SLIGHT
CHANCE DOWN TO INTERSTATE 80. ANYTHING THAT DOES POP COULD GO SEVERE
IN A HURRY WITH SUPERCELL POTENTIAL DEFINITELY THERE...ESPECIALLY IN
THE NE CWA.

.LONG TERM...WEDNESDAY THROUGH NEXT TUESDAY. BIGGEST CONCERN DURING
THIS PERIOD RELATES TO SEVERE WEATHER THREAT WEDNESDAY.

THE STAGE IS SET TOMORROW AFTERNOON FOR A VERY ACTIVE SEVERE
WEATHER DAY ACROSS MUCH OF OUR CWA.  FRONT WILL REMAIN RATHER
STATIONARY ON WEDNESDAY...POSITIONED ACROSS OUR SOUTHERN CWA LIKELY
NEAR THE NE/KS STATE LINE.  THE QUASI-STATIONARY FRONT WILL BE THE
MAJOR PLAYER IN THE HASTINGS CWA DURING THE AFTERNOON HOURS...AS THE
DRYLINE WILL BE LOCATED FURTHER WEST ACROSS WESTERN KANSAS WITH A
TRIPLE POINT NEAR OR JUST WEST OF MCCOOK NEBRASKA.  BY MID AFTERNOON
CAPE VALUES OF 2500 J/KG...0-3KM SHEAR VALUES OF 35 TO 50 KTS...0-3KM
HELICITY VALUES OF 200 TO 350 M2/S2...AND CIN NEAR 0 J/KG WILL BE
IDEAL FOR CONVECTIVE DEVELOPMENT.  THUNDERSTORMS WILL QUICKLY GO
SEVERE BY EARLY TO MID AFTERNOON WITH SEVERE HAIL AND WIND THE
GREATEST THREAT ACROSS OUR NORTHERN CWA...WHILE TORNADOES WILL ALSO
BE POSSIBLE FURTHER SOUTH IN THE VICINITY OF THE FRONT.

THE BOTTOM LINE IS FRONTAL POSITION WHICH IS DEPENDENT ON
TONIGHTS CONVECTION.  THIS WILL BE THE KEY FACTOR IN PIN POINTING THE
LOCATION OF GREATEST SEVERE THREAT.

SURFACE FRONT SLIDES SOUTHEAST OF THE AREA BY THURSDAY BRINGING AN
END TO THE SEVERE WEATHER.  HOWEVER...A FEW ELEVATED THUNDERSTORMS
WILL STILL BE POSSIBLE THURSDAY DUE TO A LIMITED AMOUNT OF
ELEVATED INSTABILITY.  UPPER TROUGH DOES NOT FINALLY SLIDE THROUGH
THE REGION UNTIL LATE FRIDAY AND HAVE KEPT A SLIGHT CHANCE OF RAIN IN
THE FORECAST UNTIL THAT TIME.

UPPER LEVEL RIDGING WILL RESULT IN A DRY WEEKEND WITH THE NEXT
CHANCE OF THUNDERSTORMS HOLDING OFF UNTIL TUESDAY.
