AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
346 PM CDT TUE JUN 22 2010
.DISCUSSION...
...SEVERE WX THREAT AND FLOODING CONTINUES...
LATEST SUBJECTIVE SFC ANALYSIS SHOWS TWO WARM FRONTS RESIDING
ACROSS THE AREA. THE FIRST OF WHICH EXTENDS FM NORTH CENTRAL
KANSAS AND HUGS THE KS/NE BORDER TO NEAR FALLS CITY. THE SECOND
BOUNDARY RESIDES ALONG THE MISSOURI RIVER VALLEY FROM NEAR YANKTON
DOWN TO SIOUX CITY AND NEAR DENISON IOWA.
SPECIAL 18Z OBSERVED KOAX SOUNDING INDICATED A CAP STILL IN PLACE.
LOOKING AT RUC ANALYSIS...MUCH OF THE AREA STILL REMAINS CAPPED
WITH EXTREME INSTABILITY ACROSS THE FORECAST AREA.
ONCE THE CAP BREAKS...WE ARE EXPECTING RAPID TSTM DEVELOPMENT WITH
AN TORNADO/HAIL THREAT TO BEGIN WITH...MAINLY UNTIL NEAR SUNSET.
0-6KM EFFECTIVE BULK SHEAR REMAINS AROUND 50+ KTS OVER MUCH OF THE
AREA. THREAT LOOKS TO TURN MORE TO A WIND/HEAVY RAIN THREAT AS
THE STORMS DEVELOP INTO A LARGE COMPLEX AND PUSH FROM WEST TO EAST
ACROSS MUCH OF THE AREA ONCE NOCTURNAL LLVL JET KICKS UP.
HEAVY RAIN IS ANOTHER THREAT ON TOP OF ALREADY SATURATED GROUND.
HAVE ISSUED A FLASH FLOOD WATCH TO COVER HEAVY RAIN POTENTIAL
OVERNIGHT. CURRENTLY HAVE QPF AMOUNTS RANGING AROUND 1-2" WITH
SOME ISOLATED 3" AMOUNTS POSSIBLE...ESPECIALLY ACROSS NORTHEAST
NEBRASKA AND MUCH OF WEST CENTRAL IOWA.
COMPLEX SHOULD EXIT THE AREA BY MID WEDNESDAY MORNING.
HIGH PRESSURE BEGINS TO BUILD INTO THE REGION ON WEDNESDAY. THIS
WILL HELP BY GIVING US A FEW DRYING DAYS. SFC DEWPOINTS SHOULD
RETREAT INTO THE UPPER 50S TO LOWER 60S BY WEDNESDAY NIGHT AND
INTO THURSDAY.
WITH A FEW DRY DAYS UNDER OUR BELT BY LATE IN THE WEEK...RETURN FLOW
WILL BE UNDERWAY BY 12Z FRIDAY AS THE SFC HIGH SLIDES EAST. STRONG
MOIST/WAA IS EXECTED OVERNIGHT FRIDAY INTO SATURDAY SOUTH OF A SFC
LOW PUSHING EAST ACROSS THE NORTHERN PLAINS. THIS LOW WILL SLIDE A
COLD FRONT SOUTH INTO THE FORECAST AREA SOMETIME SATURDAY NIGHT INTO
SUNDAY MORNING. WILL INCLUDE A TSTM CHANCE TO COVER THE FRONT SAT
NIGHT INTO SUNDAY MORNING. OTHERWISE...DRIER AND COOLER
DEWPOINTS/TEMPS WILL FOLLOW AS SFC HIGH PRESSURE BUILDS IN.
INDICATIONS CONTINUE TO SHOW THAT A BIG FAT RIDGE WILL TRY TO BUILD
INTO THE NATIONS MID SECTION FOR NEXT WEEK.

GENERALLY VFR CONDITIONS EXPECTED OUTSIDE OF THUNDERSTORMS.
THUNDERSTORMS ARE EXPECTED TO DEVELOP IN NORTHEAST
NEBRASKA...NORTHEAST OF KOFK...DURING THE LATE AFTERNOON AND

HOWEVER A COMPLEX OF THUNDERSTORMS DEVELOPING IN WESTERN NEBRASKA
WILL SWEEP INTO EASTERN NEBRASKA BETWEEN 06Z AND 15Z. GENERAL MVFR
CIGS/VSBYS ARE LIKELY AT KOFK WITH KOMA ON THE SOUTHERN FRINGE.

The Omaha radar (KOAX), 107 km away, was scanning. The volume nearest the first event began at 02:21 UTC.
8 thunderstorm wind, 3 hail, 1 flash flood, 1 flood. Local standard time, as filed.
A storm chaser measured a thunderstorm wind gust of 58 mph southeast of Friend.
Very little/no rain was falling when the hail began.
A spotter estimated that thunderstorm wind gusts reached 60 mph.
Thunderstorm winds estimated at over 60 mph downed a few trees in the Elgin area.
Thunderstorm wind gusts estimated at over 60 mph downed trees in the Neligh area.
A thunderstorm with strong winds downed large tree limbs and power lines across much of Omaha as it moved across town. The Asos at Omaha-Eppley airport measured a wind gust of 63 mph with the storm.
Law enforcement estimated that thunderstorm winds reached around 70 mph. Winds from this same thunderstorm downed trees in the Hartington area, which is several miles to the southeast, several minutes later.
Thunderstorm wind gusts estimated at over 60 mph downed trees and destroyed at least one farm outbuilding in the Hartington area.
The Asos at Tekamah measured a thunderstorm wind gust of 58 mph.
Rainfall of around 3.5 inches caused flash flooding and evacuation of campers at Bruce Park in Creighton. Creighton's city hall also sustained substantial water damage due to the heavy rain which ponded on the roof and then leaked around a flashing.
Rainfall of another 1 to 2 inches June 22 fell across parts of the Shell Creek basin near and north of Columbus. The rains fell on saturated soils due to the over 5 to 8 inches of rain that fell earlier in the month. This produced some lowland flooding along Shell Creek from near Platte Center to east of Highway 81. The high water closed county roads and Highway 81 for a while on the 23rd and 24th in addition to flooding farmland along the creek.
