What happened

The episode as NWS GID wrote it up.

Three distinct rounds of severe thunderstorms pounded parts of South Central Nebraska between the very early morning hours on the 21st, and sunrise on the 22nd, continuing a very active few days of severe weather. By and large, most of these storms affected areas near and south of Interstate 80. The first round flared up very early on the 21st, around midnight, reached peak intensity during the pre-dawn hours, and was largely out of the area by sunrise. This cluster of storms formed to the north of a nearly stationary east-west surface front stretched across Northern Kansas, within the nose of a 40-50 knot low level jet. The synoptic environment also featured at least 40 knots of deep layer shear, and MUCAPE values of 2000-3000 J/kg. For being so early in the morning, these storms were efficient damaging wind-producers near the Highway 6 corridor, with gusts to at least 70 MPH reported in parts of Phelps, Kearney and Adams Counties. In addition to damaging winds, there were also a few reports of hail, with hail up to golf ball size reported in Kearney County.

Following a break in the action that lasted most of the day and into the evening hours, another complex of severe thunderstorms started pushing into western sections of South Central Nebraska shortly after sunset, rolling through areas near and south of Interstate 80 during the next several hours, and lasting into the early morning hours on the 22nd. The synoptic situation was very similar to the first round of storms, with the same, quasi-stationary surface front hanging across Northern Kansas, 2000-3000 J/kg MUCAPE, and the nose of a 30-40 knot low level jet focused into the area. In similar fashion, these storms were primarily damaging wind-producers, with a corridor of reports of 60-75 MPH wind and associated damage centered from Harlan and Franklin Counties, east-northeast into Hamilton and Fillmore Counties. This round of storms largely exited South Central Nebraska by 2 am on the 22nd.

Finally, yet another complex of strong to severe storms flared up during the pre-dawn hours on the 22nd within the persistent warm-air advection regime, with a report of 60 MPH winds near Doniphan in Hall County shortly after sunrise.

Area forecast discussion, Jun 20, 11:15 PM CST, 3 hours 43 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
1215 AM CDT MON JUN 21 2010

.AVIATION...06Z TAF. THUNDERSTORMS HAVE DEVELOPED ALONG THE
NOSE OF THE LOW LEVEL JET IN AN AREA OF H85 WARM AIR ADVECTION.
THE COVERAGE OF THE STORMS HAS INCREASED ENOUGH THAT THE CHANCES
OF THEM REACHING KGRI LOOK HIGH ENOUGH TO CARRY A TEMPO GROUP FOR
A COUPLE OF HOURS EARLY THIS MORNING. CEILINGS ARE A BIT TRICKY
WITH STRATUS AND MVFR CEILINGS ALREADY IN LOCATIONS SUCH AT KBBW.
THE MODELS HAVE AT TIMES SHOWN THE STRATUS REACHING KGRI...AND
WILL MAINTAIN FORECAST CONTINUITY BY CARRY AN MVFR CEILING EARLY
THIS MORNING. WILL SCATTER OUT THE LOWER CLOUDS AROUND 13Z...AND
CONTINUE WITH VFR UNTIL ANOTHER CHANCE OF THUNDERSTORMS ARRIVES
AGAIN THIS EVENING DUE A FRONTAL BOUNDARY THAT WILL REMAIN IN THE
REGION.

&&

.PREV DISCUSSION... /ISSUED 246 PM CDT SUN JUN 20 2010/

SHORT TERM...TONIGHT THROUGH MONDAY NIGHT.  FOCUS IS ON SEVERE
WEATHER POTENTIAL THE NEXT COUPLE OF NIGHTS.  EARLY AFTN SFC LOW
PRESSURE WAS CENTERED IN SOUTHEAST COLORADO AND THE WARM FRONTAL
BOUNDARY STRETCHED NORTHEAST THRU WEST CENTRAL KANSAS INTO NORTH
CENTRAL KANSAS.  THIS FRONTAL POSITION IS FARTHER SOUTH THAN MODELS
PROGGED FOR TODAY AND IS SIMILAR TO THE FRONTAL BOUNDARY POSITION
ON SATURDAY. MOISTURE HAS POOLED ALONG THE BOUNDARY WITH DPS IN
THE LOWER 70S AND LATEST LAPS SHOWS SFC BASED CAPES IN EXCESS OF
4000 J/KG ALONG OUR SOUTHERN CWA AND SHEAR VALUES ARE AROUND
40KTS. VISIBLE SATELLITE IMAGERY SHOWS A CU FIELD DEVELOPING ALONG
THE FRONT IN NORTH CENTRAL KANSAS. SHLD JUST BE A MATTER OF TIME
BEFORE TSTMS REDEVELOP...AND STORMS ARE EXPECTED TO RAPIDLY BECOME
SEVERE IN THE UNSTABLE CONDITIONS. ENVIRONMENT IS SUPPORTIVE OF
SUPERCELLS AND VERY LARGE HAIL...DAMAGING WINDS AND TORNADOES IN
THE VICINITY OF THE FRONT WILL BE POSSIBLE. PRECIPITABLE WATER
VALUES ARE PROGGED FROM AN INCH AND A HALF TO JUST OVER TWO INCHES
TONIGHT AND VERY HEAVY RAINFALL IS EXPECTED...WHICH MAY LEAD TO
ADDITIONAL FLOODING. WE HAD SOME RAIN AMOUNTS OVER 3.75 INCHES IN
THE LAST 24 HOURS AND ADDITIONAL HEAVY RAINFALL ON THE ALREADY
SATURATED GROUND WILL AGGRAVATE ONGOING FLOODING AND HIGH RIVER
LEVELS. ISSUED A FLASH FLOOD WATCH EARLIER FOR SOUTH CENTRAL
NEBRASKA UNTIL 12Z MONDAY AND WILL EXTEND THIS TO OUR NORTH
CENTRAL KANSAS COUNTIES GIVEN THE FARTHER SOUTH FRONTAL POSITION.
THE LLVL JET IS PROGGED TO INCREASE TO AROUND 45KTS
OVERNIGHT...WHICH WILL SUSTAIN CONVECTION AND SEVERE POTENTIAL
REMAINS IN THE ELEVATED INSTABILITY AXIS. TIMING OF TSTMS TONIGHT
INTO TOMORROW IS NOT IN AGREEMENT AMONG MODELS WITH THE 12Z SPC
WRF SUGGESTING THAT CONVECTION WILL RAPIDLY LIFT OUT AFTER 06Z
MONDAY WHEREAS THE NAM HOLDS ONTO CONVECTION INTO MONDAY MORNING.

FRONTAL BOUNDARY POSITION ON MONDAY WILL BE SIMILAR TO THE LAST
COUPLE OF DAYS...AND MODELS AGAIN ATTEMPT TO LIFT THE FRONT TO
THE NEB BORDER...BUT WE WILL SEE. ANOTHER ROUND OF STORMS IS
EXPECTED TO DEVELOP DURING THE EVENING/NIGHT ALONG AHEAD OF THE
FRONT. ENVIRONMENTAL PARAMETERS ARE SIMILAR AND SEVERE
WEATHER/HEAVY RAIN ARE POSSIBLE AGAIN. TEMPS WILL BE DEPENDENT
UPON FRONTAL POSITION AND REMNANT CLOUD COVER WITH MAINLY 80S
EXPECTED NORTH OF THE FRONT AND 90S TO THE SOUTH.

LONG TERM...TUESDAY THROUGH SUNDAY. MAIN FORECAST CONCERNS WILL BE
CHANCES FOR THUNDERSTORMS TUESDAY THROUGH THURSDAY NIGHT AND
TEMPERATURES.

SOME LINGERING THUNDERSTORMS ARE POSSIBLE IN THE NORTHEAST PART OF
THE FORECAST AREA TUESDAY MORNING BUT THEY SHOULD DIMINISH DURING
THE DAY AND REMAIN DRY THROUGH THE DAY. A COLD FRONT MOVES INTO THE
FORECAST AREA DURING THE AFTERNOON AND AS AN UPPER WAVE MOVES INTO
THE AREA TUESDAY NIGHT THE CHANCE FOR THUNDERSTORMS RETURNS. THE
BEST CHANCE FOR THUNDERSTORMS WILL BE IN THE NORTHERN PART OF THE
FORECAST AREA CLOSER TO THE UPPER WAVE.

BY WEDNESDAY THE FRONT SINKS TO THE SOUTH AND THE UPPER WAVE IS
MOVING TO THE EAST. PRECIPITATION SHOULD BE DONE AND THE DAY LOOKS
LIKE IT SHOULD REMAIN DRY. TEMPERATURES SHOULD BE ABOVE NORMAL.

WEDNESDAY NIGHT THROUGH THURSDAY NIGHT AN UPPER LEVEL WAVE MOVES
THROUGH THE AREA AND WITH THE SURFACE LOW AND FRONT ACROSS KANSAS
AGAIN EXPECT THAT THERE COULD BE SOME SHOWERS AND THUNDERSTORMS
AROUND THE AREA. THE BEST CHANCE WILL BE WEDNESDAY NIGHT AS THE
UPPER WAVE IS THE STRONGEST DURING THAT TIME. THUNDERSTORMS MAY
LINGER INTO THURSDAY MORNING...THEN EXPECT A BIT OF A BREAK DURING
THE DAY BEFORE THE NEXT WEAK WAVE MOVES INTO THE AREA LATE IN THE
AFTERNOON OR DURING THE EVENING. TEMPERATURES SHOULD REMAIN ON THE
WARM SIDE.

FRIDAY THROUGH SUNDAY A RIDGE BUILDS INTO THE AREA. DRIER AIR
SPREADS ACROSS THE AREA AND DESPITE A FRONT MOVING THROUGH SATURDAY
AND SATURDAY NIGHT EXPECTING A DRY FORECAST. WITH THE RIDGE BUILDING
ACROSS THE AREA EXPECT THAT TEMPERATURES WILL BE MUCH WARMER THAN
NORMAL.
