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 Jun 10, 4:15 AM CDT, 2 hours 9 minutes earlier.

Area forecast discussion, Jun 10, 4:15 AM CDT, 2 hours 9 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
415 AM CDT THU JUN 10 2010

.DISCUSSION...MAIN FORECAST CONCERNS WILL BE CHANCES FOR
THUNDERSTORMS ON AND OFF THROUGH SUNDAY AND TEMPERATURES.

THUNDERSTORMS HAVE ONCE AGAIN DEVELOPED ON THE HIGH PLAINS DURING
THE NIGHT AND HAVE BEEN MOVING EAST OVERNIGHT. A SURFACE LOW
PRESSURE SYSTEM IS DEVELOPING IN THE CENTRAL ROCKIES.

THE SURFACE LOW CONTINUES TO DEVELOP AND MOVE TO THE EAST TODAY AND
TONIGHT. AN UPPER LEVEL WAVE MOVES THROUGH THE AREA THIS MORNING.
MODELS HAVE SLIGHTLY DIFFERENT SOLUTIONS FOR TODAY AND TONIGHT. THE
NAM BRING THE UPPER WAVE THROUGH THE AREA THROUGH THE MORNING BUT
MOST OF THE DIFFERENCES LIE IN THE LOCATION OF THE SURFACE LOW AND
ASSOCIATED FRONTAL BOUNDARIES. THE NAM IS A LITTLE FURTHER SOUTH AND
HAS A BOUNDARY THAT MOVES THROUGH THE FORECAST AREA LATE THIS
AFTERNOON INTO THIS EVENING. THIS BOUNDARY ALMOST SEEMS TO BE TIED
TO THE CONVECTION THAT MOVES THROUGH THE AREA DURING THIS TIME. THE
GFS IS FURTHER NORTH WITH THE SURFACE LOW AND THE MAIN FRONT REMAINS
FURTHER TO THE NORTHWEST OF THE FORECAST AREA. THE NAM SEEMS A BIT
CONVECTIVELY ENHANCED AND AM NOT CONFIDENT IN THE SOLUTION SO LEANED
A BIT MORE TOWARD THE GFS. EXPECT THAT THE CONVECTION THIS MORNING
WILL MOVE MAINLY THROUGH THE NORTHEASTERN PART OF THE FORECAST AREA
THEN EXPECT THAT THE PRECIPITATION WILL MOVE OFF TO THE NORTHEAST
THIS MORNING. AS THE SURFACE LOW DEVELOPS THIS AFTERNOON SOUTH WINDS
WILL INCREASE ACROSS THE AREA AND EXPECT BREEZY CONDITIONS DURING
THE AFTERNOON. THUNDERSTORMS WILL AGAIN DEVELOP ON THE HIGH PLAINS
THIS AFTERNOON IN THE VICINITY OF THE FRONT AS IT MOVES THROUGH
NORTHERN NEBRASKA. A FEW OF THEM COULD WORK THEIR WAY INTO THE
NORTHERN PART OF THE FORECAST AREA THIS AFTERNOON. TONIGHT THE
THUNDERSTORMS WILL CONTINUE TO MOVE MAINLY THROUGH NORTHERN NEBRASKA
AS THE SURFACE LOW AND COLD FRONT APPROACH THE AREA. THUNDERSTORMS
ARE EXPECTED TO CONTINUE LATE TONIGHT ALONG THE FRONT NEAR WHERE THE
UPPER WAVE IS.

ON FRIDAY THE FRONT MOVES THROUGH THE FORECAST AREA. THUNDERSTORMS
ARE POSSIBLE MAINLY IN THE NORTHERN PART OF THE FORECAST AREA AS
THUNDERSTORMS ARE EXPECTED TO DEVELOP NEAR THE FRONT AS IT MOVES
THROUGH. BY AFTERNOON AND EVENING THE THUNDERSTORMS WILL SPREAD
ACROSS THE FORECAST AREA. SOME OF THESE STORMS COULD BE STRONG TO
SEVERE. AN UPPER WAVE MOVES ACROSS THE NORTHERN PART OF THE FORECAST
AREA AND KEEPS THUNDERSTORMS POSSIBLE THROUGH THE NIGHT.
THUNDERSTORMS CONTINUE SATURDAY AND SATURDAY NIGHT AS ANOTHER WAVE
MOVES INTO THE AREA. MADE NO CHANGES TO SUNDAY AND BEYOND.

.PREV DISCUSSION... /ISSUED 1214 AM CDT THU JUN 10 2010/

AVIATION...06Z TAF. SOME LIGHT SHOWERS OR SPRINKLES WILL BE IN
THE VCNTY OF KGRI AT THE ONSET OF THE TAF PERIOD...WHILE THE MAIN
SHOWER AND THUNDERSTORM ACTIVITY RESIDES ACROSS THE HIGH PLAINS
AND NORTHERN NEBRASKA. THE WESTERN CONVECTION IS EXPECTED TO ROLL
EASTWARD INTO SOUTH CENTRAL NEBRASKA AROUND THE 09Z TIME
FRAME...WITH PCPN LINGERING INTO THE MORNING HOURS. WINDS WILL BE
FROM A SOUTHERLY DIRECTION AND GUST NEAR 25KTS AT TIMES FM MID
MORNING THURSDAY INTO THE AFTERNOON. CLOUD HEIGHTS WILL BE IN THE
