A cold front that moved across the area kicked off a relatively small complex of severe thunderstorms over east central and southeast Nebraska and southwest Iowa.

What happened
The episode as NWS OAX wrote it up.
A cold front that moved across the area kicked off a relatively small complex of severe thunderstorms over east central and southeast Nebraska and southwest Iowa. Initially, as the front came through during the late afternoon hours, warm mid level temperatures limited coverage and strength of the activity. However, around sunset mid level cooling, aided by a weak upper level disturbance, helped increase the strength of convection that was developing above the cap just to the west of the area. These thunderstorms then tracked across the region and produced areas of damaging winds, mostly in southeast Nebraska, along with one report of large hail in western Iowa.

Area forecast discussion, Jul 11, 12:53 PM CST, 10 hours 32 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 153 PM CDT FRI JUL 11 2008 .DISCUSSION... THE CHANCE FOR SEVERE THUNDERSTORMS TONIGHT IS THE PRIMARY FORECAST CONCERN...WITH A MILD WEEKEND TO FOLLOW. COLD FRONT WAS CONTINUING TO PROGRESS INTO NORTH CENTRAL NEBRASKA THIS AFTERNOON WITH GUSTY SOUTH WINDS MAINTAINING LOW 70S DEW POINTS ACROSS EASTERN NEBRASKA AND SOUTHWEST IOWA. A WEAK UPPER IMPULSE WAS NOTED EXITING THE HIGH PLAINS WITH MID LEVEL ACCAS SHOWN ON VISIBLE SATELLITE PICS PUSHING INTO CENTRAL NEBRASKA...AND SOME RETURNS WERE STARTING TO SHOW UP ON AREA RADARS. MORNING SOUNDINGS AND LATEST RUC ANALYSES WERE SHOWING STRONG CAP ACROSS MUCH OF OUR CWA WITH 700 MB TEMPS IN THE 12-14C RANGE...BUT ACCAS AND ASSOCIATED VIRGA MAY HELP ERODE CAP. ALSO SOME WEAKNESS IN THE CAP WAS SHOWN OVER THE EASTERN CWA WHERE AXIS OF 3000-4000J/KG SBCAPES WERE SHOWN IN RUC SHORT RANGE FORECASTS. NOT SEEING DEVELOPMENT THERE JUST YET AS LOW LEVEL MOISTURE CONVERGENCE IS NON- EXISTENT...BUT WILL HAVE TO WATCH THE AREA FROM FAR SOUTHEAST NEBRASKA THROUGH OMAHA AND EAST FOR SOME POTENTIAL IGNITION THROUGH THE AFTERNOON. MAIN FOCUS FOR STORMS WILL BE WITH THE COLD FRONT...WHICH IS SCHEDULED TO ARRIVE IN THE NORTHWEST CWA LATER THIS AFTERNOON. NAM AND RUC INDICATE FRONT SHOULD BE ALONG A WAYNE TO ALBION LINE BY 23Z WITH STORMS BEGINNING JUST BEFORE. ACCAS TO THE WEST MAY FORETELL WEAKER CAP MOVING OVERHEAD...SO COULD SEE SOME STORMS BEFORE THIS TIME. SBCAPES ARE APPROACHING 4000 J/KG AHEAD OF THE FRONT FROM CENTRAL NEBRASKA THROUGH NORTHEAST NEBRASKA...SO IF CAP DOES BREAK WE SHOULD SEE STRONG UPDRAFTS. 0-6KM BULK SHEAR IS RELATIVELY WEAK...LESS THAN 30 KTS...AND IS NOT EXPECTED TO INCREASE MUCH AT ALL. SO PRIMARY CONVECTIVE MODE WILL BE SINGLE CELL STORMS WITH THE POTENTIAL FOR HAIL AND DAMAGING MICROBURSTS INITIALLY. AS FRONT CONTINUES ITS PROGRESS THROUGH THE CWA IN THE EVENING...WIND THREAT WILL INTENSIFY IF STORMS CAN LINE UP ON THE FRONT AND TAKE ADVANTAGE OF HIGH DOWNDRAFT CAPE AND LARGE TEMPERATURE/DEW POINT SPREADS. HAVE CONTINUED CHANCE TO LIKELY POPS ALONG THE FRONT AS IS PASSES THROUGH THE CWA THIS EVENING...BUT FRONT SHOULD BE EXITING THE SOUTHERN CWA AROUND OR JUST PAST MIDNIGHT. WILL MAINTAIN CHANCE POPS OVERNIGHT AS SEVERAL MID LEVEL IMPULSES RIDE THROUGH SOUTHERN AND EASTERN NEBRASKA...BUT SEVERE THREAT SHOULD BE CONFINED TO THE EVENING HOURS. FRONT WILL BE SOUTH OF THE AREA ON SATURDAY...BUT CAN NOT RULE OUT A MORNING SHOWER OR STORM IN FAR SOUTHEAST NEBRASKA AND SOUTHWEST IOWA. SURFACE HIGH PRESSURE WILL CLEAR SKIES FROM NORTH TO SOUTH ON SATURDAY...BRINGING IN COOLER AND DRIER AIR. HIGHS ON SATURDAY SHOULD ONLY REACH THE LOWER 80S IN MOST AREAS WITH DEW POINTS IN THE 50S. A RATHER COOL NIGHT SATURDAY NIGHT WITH CLEAR SKIES...LOW DEW POINTS AND LIGHT WINDS. HAVE MOST LOWS IN THE 50S. SUNDAY SHOULD ALSO BE PLEASANT WITH RELATIVELY LOW DEW POINTS...TEMPS IN THE MIDDLE 80S AND MOSTLY SUNNY SKIES. RETURN FLOW BEGINS SUNDAY NIGHT AS SURFACE HIGH SLIDES OFF TO THE EAST. WEAK UPPER RIDGING WILL ALSO BEGIN...BRINGING A WARMER AND CAPPED ATMOSPHERE TO THE PLAINS. HIGHS SHOULD CLIMB TOWARD 90 MONDAY AND TUESDAY...THEN INTO THE 90S WEDNESDAY AND THURSDAY. WEAK IMPULSES COULD TRIGGER A FEW STORMS TUESDAY THROUGH WEDNESDAY...BUT WILL KEEP CHANCES FAIRLY LOW GIVEN WARM MID LEVEL TEMPERATURES. MORE LIKELY TO SEE LATE NIGHT STORMS DEVELOPING ABOVE THE CAP ON NOSE OF LOW LEVEL JET. BETTER CHANCES FOR STORMS COME THURSDAY AND FRIDAY AS PER GFS AND ECMWF FORECASTS. WEAK UPPER RIDGE IS BROKEN DOWN AS SHORT WAVES RIDE THROUGH THE NORTHERN PLAINS...ALLOWING A COLD FRONT TO APPROACH THE CWA THURSDAY. COOLER AIR ALOFT SHOULD ALLOW STORMS TO FIRE NEAR THE FRONT THURSDAY...WITH THAT FRONT DRIFTING SOUTH THROUGH THE NIGHT INTO FRIDAY. && .AVIATION... FOR TAF SITES KOMA/KLNK/KOFK. PREDOMINATE VFR CONDITIONS THROUGH THE PERIOD WITH OCNL MVFR CONDITIONS 00Z-06Z AS SCT CONVECTION DEVELOPS ALONG A COLD FRONT MOVING THROUGH THE AREA. WINDS SHIFTING TO THE NORTH BEHIND THE FRONT. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...NONE. IA...NONE. && DERGAN/FOBERT
