These thunderstorms tracked east across east central Nebraska during the late night hours of June 25th and produced a narrow band of 2 to 3 inch rainfall from near David City through Omaha and Council Bluffs. The rain fell in a several hour period and produced isolated flash flooding, mainly in the Omaha and Council Bluffs area.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 320 AM CDT SAT JUN 25 2011 .DISCUSSION... SOMEWHAT COMPLEX ONGOING CONVECTIVE SCENARIO THIS MORNING WITH A COUPLE AREAS OF FOCUS. THE INITIAL MCS THAT DEVELOPED OVER NORTH CENTRAL NEBRASKA DID PUSH THROUGH NORTHEAST NEBRASKA AROUND MIDNIGHT...BUT HAD WEAKENED CONSIDERABLY EARLY THIS MORNING. MEANWHILE...CONVECTION STRENGTHENED CONSIDERABLY ALONG INTERSTATE 80 AS THE NOSE OF THE LOW LEVEL JET FINALLY MAXIMIZED...RESULTING IN FAIRLY STRONG THUNDERSTORMS PUSHING EASTWARD...WITH A COUPLE LARGER HAIL REPORTS ACROSS SOUTH CENTRAL NEBRASKA. THIS ENTIRE CLUSTER WILL CONTINUE TO PUSH EASTWARD THIS MORNING ALONG I80...AND MAY BLOCK MOISTURE TRANSPORT FURTHER NORTH INTO NORTHEAST NEBRASKA...ALTHOUGH SCATTERED SHOWERS WILL STILL BE POSSIBLE THERE. BASED ON LOW LEVEL JET PROGS...SLIGHTLY LOWER CHANCES MAY EXIST ALONG THE KS/NE BORDER REGION AS THE AREA OF BEST CONVERGENCE SETS UP JUST NORTH. FOR THIS AFTERNOON...THE BACK EDGE OF THAT MCS COULD STILL BE ACROSS EASTERN NEBRASKA AND WESTERN IOWA...MEANWHILE...ANOTHER VERY SUBTLE WAVE WITH SCATTERED CONVECTION COULD BE MOVING OUT OF SOUTH DAKOTA INTO NORTHEAST NEBRASKA THIS AFTERNOON AS WELL...WHICH COULD LINGER THROUGH THE EARLY EVENING. DUE TO CLOUDS AND RAIN...OPTED FOR SLIGHTLY COOLER TEMPS TODAY. FEEL THAT MOST OF THE AREA WILL BY DRY AFTER MIDNIGHT...AND ATTENTION SHIFTS TO POSSIBLE DEVELOPING STRATUS AND AREAS FOG BY DAYBREAK. VERY MOIST BOUNDARY LAYER SETS UP WITH A VERY LOW TEMP/DEWPOINT SPREAD THROUGH THE NIGHT. ALL MODEL SUITES ARE SUGGESTING THIS...THUS UPPED THE CLOUD FORECAST AND ADDED FOG TO THE GRIDS. DID NOT MENTION DENSE FOG JUST YET GIVEN WINDS ARE NOT FORECAST TO COMPLETELY DECOUPLE AS WITH A TYPICAL AREA OF HIGH PRESSURE AND CLEAR SKIES OVERHEAD. LINGERED STRATUS AND FOG INTO EARLY SUNDAY MORNING. NEXT ADVANCING WAVE IS FORECAST TO PUSH A FAIRLY STRONG COOL FRONT INTO THE AREA SUNDAY NIGHT. THIS WILL ALLOW ANOTHER MCS TO DEVELOP AND AFFECT AREAS ESPECIALLY NORTH OF INTERSTATE 80...THUS HAVE INCREASED POPS INTO THE LIKELY CATEGORY. COULD ALSO SEE ISOLATED THUNDERSTORMS NORTH OF THE STALLED FRONT ACROSS SOUTHEAST NEBRASKA SUNDAY AFTERNOON TOO. BY MONDAY...THE MODELS ARE A LITTLE DIFFERENT WITH THE TIMING OF THE FRONT...BUT TRIED TO FORECAST A COMPROMISE...WHICH WOULD STILL SUGGEST A CHANCE OF SHOWERS AND THUNDERSTORMS MOVING THROUGH...BUT ENDING FROM NORTHWEST TO SOUTHEAST...WITH GUSTY NORTHWESTERLY WINDS COMING IN BEHIND AND CLEARING SKIES. BRIEF BREAK ON TUESDAY...BUT DID INCREASE POPS FOR TUESDAY NIGHT AS WARM AIR ADVECTION COULD TRIGGER ADDITIONAL STORMS. && .AVIATION... TAF SITES KOFK/KOMA/KLNK 06Z TAFS POTENT LITTLE UPPER DISTURBANCE OVER THE CNTRL PLAINS THIS MORNING KICKING OFF SCATTERED TSRA MOVING THRU ERN NEB AROUND 25KT. AT THIS POINT APPEARS THAT KOMA/KLNK AT RISK TO SEE EARLY MORNING CONVECTION WITH ACTIVITY PUSHING INTO BOTH TERMINALS AROUND 09Z WITH MVFR CONDITIONS PREVAILING. EXPECT TSRA ACTIVITY WILL THEN EXIT KOMA/KLNK BTWN 12Z-13Z. MEANWHILE AT KOFK...CONDITIONS WILL DROP FROM VFR TO MVFR THRU 13Z THIS MORNING WITH OCCASIONAL -SHRA. AFT 13Z MVFR CIGS EXPECTED AT ALL SITES THRU 18Z...THEN IMPROVEMENT TO VFR THE REST OF THE FCST PD. DEE && .HYDROLOGY... THE MBRFC RELEASED A NEW SET OF LONG RANGE CREST FORECASTS FOR THE MISSOURI RIVER BASED ON 160 KCFS RELEASE OUT OF GAVINS POINT. IN GENERAL...THE BROAD RANGES STILL SEEM ON TRACK. NO ADDITIONAL INFORMATION REGARDING LEVEES ACROSS THE REGION. THE STAGE AT BROWNVILLE APPEARS TO BE LEVELING OUT...THUS EQUALIZING THE SIGNIFICANT DROP DUE TO THE L550 BREECH THAT OCCURRED THURSDAY EVENING. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...NONE.
