Did it verify

Verified. The Iowa Environmental Mesonet's Cow matched one storm report to this flash flood warning; the first came 243 minutes after it went out.

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.

AREA FORECAST DISCUSSION

1104 PM CDT SUN JUN 20 2010

.UPDATE...
UPDATED TO DROP TORNADO WATCH.

&&

.PREV DISCUSSION... /ISSUED 325 PM CDT SUN JUN 20 2010/

..CORRECTION FOR TYPO...

DISCUSSION...
WE ARE WATCHING SERN WY AND CNTL/SWRN NEB FOR STORM DEVELOPMENT
AND HEAVY RAIN.

REPEATED MCS DEVELOPMENT OF THE PAST 24 HOURS HAS DISRUPTED THE SFC
AIR MASS SUBSTANTIALLY. STRATUS AND HIGH PRESSURE HAS BUILT IN
STABILIZING THE SFC MOMENTARILY. THE RUC IS LIFTING THE SFC WARM
FRONT ACROSS NRN KS UNEVENTFULLY INTO NCNTL NEB BY 06Z TONIGHT.
SINCE THE MODEL DOESNT DEVELOP ANY MEANINGFUL QPF THIS SOLN IS
SUSPECT. THE 12Z GFS LIGHTS UP THE FRONT BETWEEN KGRI AND KOFK
WHILE THE 12Z NAM LIGHTS UP BETWEEN KHDE AND KGRI. THE RUC DOESNT
LIGHT UP THE FRONT ANYWHERE. BASED ON THE 19Z SFC ANALYSIS AND THE
ACTIVITY DEVELOPING ACROSS SERN WY...NCNTL NEB OR NERN NEB COULD
BE THE AREA FOR HEAVY RAIN LATER TONIGHT. THAT IS ASSUMING THE FRONT IS
ABLE TO MOVE NORTH WITHOUT LIGHTING UP ACROSS SRN NEB.

SPC DREW A GIGANTIC AREA OF SLIGHT AND MODERATE RISK...GENERALLY
CENTERED OVER NCNTL NEB. HPC HIGHLIGHTED EASTERN NEB FOR EXCESSIVE
RAINFALL TONIGHT. WHERE EVER THE FRONT LIGHTS UP FIRST WILL LIKELY
BE THE LOCATION OF THE HEAVY RAIN CENTER. KOAX AND KGID HAVE FLOOD
WATCHES OPERATING ACROSS ALL OF CNTL AND ERN NEB AND OUR FLOOD
WATCH OPERATES GENERALLY ALONG AND EAST OF HIGHWAY 83. THE FARTHER
NORTH THE SFC BASED CONVECTION DEVELOPS THE MORE LIKELY FLOODING
WILL DEVELOP ACROSS NCNTL NEB. THE WARM FRONT SHOULD LIFT SLOWLY
NORTH OVERNIGHT AS THE H850 JET INCREASES TO NEAR 50KT.
PRECIPITABLE WATER IS EXPECTED TO EXCEED 1.5 INCHES ALONG AND EAST
OF HIGHWAY 183 AND THE DEVELOPING CONVECTION WILL WAGE WAR WITH
THE NORTHWARD PROGRESS OF THE FRONT.

MEANWHILE THE CONVECTION AND ATTENDANT UPPER LEVEL DISTURBANCE
ACROSS THE CNTL ROCKIES SHOULD MOVE NORTHEAST OVERNIGHT KICKING
THE SFC FRONT SOUTH SOMEWHAT. ANOTHER DEEP WEST COAST TROF
PROMISES ADDITIONAL DISTURBANCES DAILY ACROSS THE CNTL PLAINS
THROUGH AT LEAST WEDNESDAY NIGHT. SHEAR AND CAPE WILL BE
SUFFICIENT FOR SEVERE STORM DEVELOPMENT WHICH WILL LIKELY FOCUS
ALONG THE SFC FRONT...WHERE EVER THAT ENDS UP DURING PEAK HEATING.
BASED ON THE EXPECTED AMOUNT OF CONVECTION THE FRONT WOULD LIKELY
DRIFT SOUTH INTO KS AT NIGHT IN THE WAKE OF THE CONVECTION AND
THEN FIGHT ITS WAY NORTH DURING MORNING...AFTERNOON AND EVENING.

THE OFFICIAL FCST USES BLENDED QPF AND POPS PLUS 10...33 PERCENT
GFS AND 67 PERCENT NAM. OVERALL THE NAM WAS PREFERRED AS IT FCST
COOLER TEMPS BETTER THAN THE GFS. THE NAM NOSES THE FRONT NORTH
ABOUT 100 MILES NORTH EACH DAY MONDAY AND TUESDAY. DISTURBANCES
ARE EXPECTED TO OPERATE ON THE FRONT DAILY. BY WEDNESDAY
MORNING...THE ORIGINAL WRN U.S. TROF HAS LIFTED COMPLETELY OUT
AND HIGH PRESSURE HAS BUILT INTO NEB.

THURSDAY THROUGH SUNDAY...A NEW TROF DEVELOPS OUT WEST AS A STRONG
UPPER LEVEL RIDGE CONTINUES CENTERED OVER THE SOUTHEAST U.S.
SUBTROPICAL MOISTURE WILL CONTINUE TO CIRCULATE NORTH AROUND THIS
RIDGE AND THROUGH THE CNTL AND NRN PLAINS. THE FCST CONTINUES
ISOLATED TO SCATTERED POPS MAINLY AT NIGHT AS THE ATM IS EXPECTED
TO BE STRONGLY CAPPED MOST DAYS.

AVIATION...
STRATUS IS SLOW TO ERODE TODAY ACROSS WESTERN AND SOUTHERN PORTIONS
OF THE FORECAST AREA...WITH MOSTLY VFR CONDITIONS NOTED.
ALTHOUGH...MVFR AND LOWER CIGS CONTINUE TO BE REPORTED IN AND NEAR
ANY THUNDERSTORM AS WELL AS ACROSS PORTIONS OF THE SOUTHWESTERN
PANHANDLE OF NEBRASKA WHERE FOG IS STILL REPORTED.  EXPECTED SCT
TSRA TO DEVELOP LATER TODAY AND TONIGHT AS MOISTURE REMAINS ENTRENCHED
ACROSS THE FORECAST AREA.  SEVERAL BOUNDARIES COULD SERVE AS THE
FOCAL POINT FOR DEVELOPMENT WHICH WOULD LEAD TO A COMPLEX OF STORMS
THAT COULD PRODUCE VERY LARGE HAIL...HEAVY RAIN AND STRONG WIND
GUSTS FOR BOTH KLBF AND KVTN TERMINALS.  THE MOST LIKELY TIME FRAME
FOR TSRA WILL BE SOMETIME AFTER 03Z AND LASTING THROUGH 06Z...HOWEVER
STORMS HAVE BEEN FORMING THROUGHOUT THE MORNING/DAY...SO CONFIDENCE
IS NOT HIGH ON INITIATION TIME.  AFTER THE CONVECTIVE EVENT
PASSES...THE FORMATION OF LOW STRATUS AND/OR FOG WILL BE CERTAINLY
POSSIBLE TOMORROW MORNING...CURRENT THINKING IS THAT CIGS TOMORROW
MORNING WILL REMAIN IN THE VFR FLIGHT CATEGORY.  FOR THE VALENTINE
TERMINAL...FOG MAY BE AN ISSUE...THEREFORE INCLUDED THE MENTION OF
REDUCED VSBYS TO ACCOUNT FOR THE POTENTIAL DEVELOPMENT.

HYDROLOGY...
RIVER CONCERNS DUE TO CONTINUED RELEASES FROM UPSTREAM RESERVOIRS
ALONG THE NORTH PLATTE RIVER ARE BY NOW WELL KNOWN.  FLOOD WARNINGS
CONTINUE FOR LISCO AND LEWELLEN.  OTHER POINTS SUCH AS THE NORTH
PLATTE RIVER IN NORTH PLATTE AND BRADY ARE BEING MONITORED FOR
FUTURE STATEMENTS.

THE SOUTH PLATTE RIVER IN AND NEAR ROSCOE HAS NOW
RISEN ABOVE FLOOD STAGE...THIS IS DUE TO RAPID SNOW MELT ACROSS THE
COLORADO ROCKIES COMBINED WITH HEAVY RAINFALL OVER NORTHEASTERN
COLORADO EARLIER LAST WEEK.  A FLOOD WARNING WAS ISSUED FOR THE
RIVER AS THE CREST IS NOT EXPECTED UNTIL EARLY TOMORROW AFTERNOON.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF WESTERN AND
NORTH CENTRAL NEBRASKA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

THERE IS A MODERATE RISK FOR SEVERE THUNDERSTORMS LATER THIS
AFTERNOON AND TONIGHT AS A VERY MOIST AND UNSTABLE ATMOSPHERE
EXISTS OVER THE FORECAST AREA. AN EAST TO WEST FRONTAL BOUNDARY
WILL TRAVERSE NORTH ACROSS NEBRASKA SERVING AS THE FOCUS FOR
THUNDERSTORM DEVELOPMENT. THE MAIN THREAT FROM ANY STORM THAT
DEVELOPS IS EXTREMELY LARGE HAIL AND STRONG WIND GUSTS...HOWEVER
GIVEN SUFFICIENT SHEAR IN THE ATMOSPHERE...THE THREAT OF A TORNADO
IS POSSIBLE. LATER IN THE EVENT...AS A STRONG LOW LEVEL JET
DEVELOPS OVERNIGHT...THE STORMS WILL TRANSITION INTO A CONVECTIVE
COMPLEX CAPABLE OF PRODUCING TORRENTIAL RAINFALL AND STRONG
DAMAGING WINDS. GIVEN RECENT RAINFALL OVER MUCH OF THE
REGION...FLOODING OF CREEKS AND RIVERS IS CERTAINLY
POSSIBLE...ESPECIALLY IF THUNDERSTORMS TRAIN OVER THE SAME AREA.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.

THE FRONTAL BOUNDARY WILL REMAIN IN AND NEAR THE FORECAST AREA
THROUGH MID WEEK...ALLOWING FOR THE POTENTIAL OF MORE
THUNDERSTORMS...SOME OF WHICH MAY BE SEVERE. ABUNDANT MOISTURE
AND INSTABILITY IS EXPECTED...THUS HEAVY RAINFALL IS LIKELY IN THE
REGION...THIS WOULD EXACERBATE THE FLOODING THREAT FURTHER.

SPOTTER ACTIVATION WILL LIKELY BE NEEDED.
