What happened
The episode as NWS OAX wrote it up.
Isolated strong thunderstorms tracked across far northeast and far southeast Nebraska during the predawn hours of July 10. The storms formed near weak boundaries that were in place across the area. Warm mid level temperatures apparently helped limit the areal coverage of the storms in the morning and suppressed additional activity later that afternoon.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 314 PM CDT THU JUL 9 2009 .DISCUSSION... OR .SHORT TERM...TONIGHT FORECAST CONCERNS TONIGHT WILL BE THUNDERSTORMS WITH POTENTIAL FOR SEVERE WEATHER AND HEAVY RAIN. A COLD FRONT IS MOVING INTO NORTHEAST AND CENTRAL NEBRASKA AND WILL PROVIDE THE FOCUS FOR THUNDERSTORMS. IN ADDITION...THE COMPLEX THAT MOVED ACROSS EASTERN NEBRASKA AND SOUTHWEST IOWA THIS MORNING PUT OUT AND OUTFLOW BOUNDARY...WHICH DRAMATICALLY COOLED TEMPERATURES AND INHIBITED SURFACE WARMING WITH EASTERLY WINDS. IN ADDITION...THE 19Z OAX SOUNDING SHOWED VERY WARM MID LEVEL TEMPERATURES AT H7 AROUND 14 DEG C. FARTHER NORTH...ON THE EDGE OF THE MID LEVEL CAP...AND ALONG THE SOUTHERN GRADIENT OF THE STRONGER MID LEVEL WINDS...STORMS HAVE BEGUN TO RE-FIRE.

THUS...HAVE HIGH POPS IN THE NORTHERN THIRD OF THE CWA WITH DECREASING CHANCES TOWARD THE KS BORDER. THE CAVEAT IS THE FACT THAT THE OUTFLOW BOUNDARY MAY PROVIDE A SECONDARY FOCUS FOR STORMS AS TEMPERATURES HEAT UP INTO THE LOWER AND MID 90S AND THERE IS GOOD LOW LEVEL CONVERGENCE HERE. SEVERE STORMS ARE ONGOING AND THERE IS AND AXIS OF MUCAPE OF 2000-3000 J/KG AHEAD OF THE CDFNT...STEEP MID LEVEL LAPSE RATES...AND 0-6KM BULK SHEAR OF 50KTS...SO EXPECT SEVERE WEATHER TO CONTINUE TONIGHT.

THE TRANSPORT VECTORS INITIALLY TAKE THE STORMS FROM WEST TO EAST...THE MORE NORTHWEST TO SOUTHEAST OVERNIGHT. THE FLASH FLOOD GUIDANCE LOOKS LIKE IT MANY LOCATIONS CAN HANDLE THE HEAVY RAIN...HOWEVER...STILL COULD EXPERIENCE LOCAL ISSUES. WILL LIKELY ISSUE A FLASH FLOOD WATCH FOR THESE COUNTIES THAT HAD HEAVY RAIN THIS MORNING...AS THEY COULD SEE ANOTHER 1 TO 3 INCHES OVERNIGHT. IF CONVECTION GETS GOING IN THE BIE AREA...WILL NEED TO WATCH THIS AS THIS BOUNDARY COULD ALSO BE A FOCUS FOR HEAVY RAIN WITH THE STRENGTHENING 50KT LOW LEVEL JET OVER KS. .LONG TERM...FRIDAY THROUGH THURSDAY.
