What happened

The episode as NWS GID wrote it up.

Between 9 pm CDT on Wednesday evening the 18th and 7am CDT Thursday the 19th, the majority of the 24-county South Central Nebraska area observed one or more rounds of predominantly non-severe thunderstorm activity. Although radar signatures and automated wind sensors indicated that a few storms were likely strong to potentially marginally severe, ground-truth storm reports were quite scarce during these overnight hours. The only verifiable report of severe weather in the local area occurred in the form of a measured 66 MPH gust at the Ord airport shortly before 3 am CDT, as a small but vigorous line of storms surged into Valley County and vicinity from the southwest. Shortly after producing these strong winds, this convective line steadily weakened and the severe threat subsided.

As for convective evolution during the evening and overnight hours, the first isolated strong storm crossed out of Kansas into Harlan and Franklin counties between 9-10 pm CDT. Renewed strong development along the eastern periphery of this initial storm lifted northeast through the Hastings and Aurora areas through around midnight CDT before weakening. Meanwhile, a separate, semi-organized line of strong storms gradually developed east-northeast out of western Nebraska into western and northern portions of South Central Nebraska mainly between 1230 am and 3 am CDT. During this time frame, the northern part of this line briefly intensified into a small-scale bowing segment, producing the severe winds in the Ord area. Through the remainder of the night, a cluster of fairly weak thunderstorms rumbled eastward across the majority of South Central Nebraska before dissipating and/or exiting eastward by around sunrise. In the big picture of the mid-upper levels, overnight convection was driven by a series of low amplitude disturbances ejecting northeastward across the Central Plains in south-southwesterly flow, well to the southeast of a parent closed mid level low anchored over the Montana-Alberta-Saskatchewan border area. At the surface, most convection concentrated along and just behind a slow-moving cold front drifting west-to-east across South Central Nebraska. The uptick in storm coverage late in the night was also aided by increasing low-mid level convergence in the 850-700 millibar layer, and within the nose of a 40-50 knot low level jet aimed into the area. Around the time of the severe wind gust at Ord, the mesoscale environment featured around 1000 J/kg most-unstable CAPE and 40-50 knots of 0-6 kilometer deep layer wind shear.

.SHORT TERM...(THIS EVENING THROUGH THURSDAY)
ISSUED AT 422 PM CDT WED JUN 18 2014

MAP ANALYSIS INDICATES AN UPPER TROPOSPHERIC TROUGH OVER THE WESTERN
CONUS...AND A CLOSED LOW EMBEDDED WITHIN THE TROUGH OVER PORTIONS OF
MONTANA. AN UPPER TROPOSPHERIC RIDGE IS ALSO NOTED EXTENDING FROM
THE SOUTHEASTERN CONUS INTO THE MID-ATLANTIC. FINALLY...AN UPPER
TROPOSPHERIC SHORT WAVE...PIVOTING SOUTH OF THE CLOSE LOW...IS NOTED
BEGINNING TO EMERGE FROM THE LONGWAVE TROUGH INTO PORTIONS OF
COLORADO. ENHANCED UPPER TROPOSPHERIC FLOW EXTENDS FROM THE
NORTHWESTERN CONUS...SOUTH INTO THE SOUTHWESTERN CONUS...AND THEN
NORTHEAST ALONG THE ROCKY MOUNTAIN RANGE INTO SOUTH CENTRAL
CANADA...AND THEN EAST/SOUTHEAST INTO THE GREAT LAKES REGION AND THE
NORTHEASTERN CONUS. UPPER TROPOSPHERIC FLOW OVER OUR AREA IS FAIRLY
WEAK...ONLY MAXING OUT AT AROUND 30KTS NEAR 37000FT AGL. WATER VAPOR
IMAGERY INDICATES ENHANCED UPPER TROPOSPHERIC MOISTURE EXTENDING
FROM SOUTH CENTRAL CANADA...SOUTHEAST INTO THE GREAT LAKES REGION
AND THE NORTHEASTERN CONUS. AT THE SURFACE AN AREA OF LOW BAROMETRIC
PRESSURE IS NOTED OVER EASTERN COLORADO...WITH ANOTHER AREA OF LOW
BAROMETRIC PRESSURE OVER CENTRAL NEBRASKA. A LOWER TROPOSPHERIC
BAROCLINIC ZONE IS NOTED EXTENDING FROM EASTERN COLORADO...NORTHEAST
INTO CENTRAL NEBRASKA..AND THEN FARTHER NORTHEAST INTO SOUTHEASTERN
SOUTH DAKOTA. AN INVERTED SURFACE TROUGH EXTENDS NORTH FROM THE
CENTRAL NEBRASKA LOW...INTO NORTH CENTRAL NEBRASKA AND CENTRAL SOUTH
DAKOTA...AND A DRY LINE IS NOTED EXTENDING ACROSS PORTIONS OF
WESTERN KANSAS. THE LOWER TROPOSPHERIC WIND FIELD ACROSS EASTERN
PORTIONS OF OUR CWA REMAINS FROM THE SOUTH...BUT LOCATIONS FARTHER
WEST...TO THE WEST OF THE LOWER TROPOSPHERIC BAROCLINIC ZONE...IS
OBSERVING A WEST/NORTHWESTERLY WIND FIELD.

GUIDANCE SUGGESTS THE CLOSED UPPER TROPOSPHERIC LOW OVER MONTANA
WILL MOVE NORTHEAST THROUGH THE NEXT 24 HOURS...POSITIONING ITSELF
OVER SOUTHERN SASKATCHEWAN BY 00Z FRIDAY. THE UPPER TROPOSPHERIC
SHORT WAVE...CURRENTLY OVER COLORADO...IS ALSO EXPECTED TO MOVE
NORTHEAST THROUGH THE NEXT 24 HOURS...MOVING INTO THE CENTRAL HIGH
PLAINS BY 12Z THURSDAY AND INTO THE NORTHERN PLAINS BY 00Z FRIDAY.
AT THE SURFACE...THE AREAS OF LOW BAROMETRIC PRESSURE OVER CENTRAL
NEBRASKA AND EASTERN COLORADO ARE EXPECTED TO MOVE NORTHEAST THROUGH
THE NEXT 24 HOURS...THUS ALLOWING THE LOWER TROPOSPHERIC BAROCLINIC
ZONE TO MOVE EAST/SOUTHEAST ACROSS OUR AREA. THIS BAROCLINIC ZONE IS
EXPECTED TO RESIDE OVER SOUTHEASTERN PORTIONS OF OUR CWA BY 12Z
THURSDAY...AND CLEAR THE ENTIRE CWA THURSDAY AFTERNOON. THIS WILL
ALLOW FOR A NORTHWESTERLY LOWER TROPOSPHERIC WIND FIELD ACROSS THE
ENTIRE CWA BY 00Z FRIDAY.

GUIDANCE CONTINUES TO SUGGEST ISOLATED DEEP CONVECTION REMAINS
POSSIBLE ACROSS PORTIONS OF THE CWA LATE THIS AFTERNOON INTO THIS
EVENING. A SUBTLE INCREASE IN OMEGA AHEAD OF THE UPPER TROPOSPHERIC
SHORT WAVE OVER COLORADO...ALONG WITH DECREASING CIN VALUES...WOULD
SUGGEST THIS ISOLATED ACTIVITY COULD BE REALIZED MOST ANYWHERE
ACROSS THE CWA. THAT BEING SAID...PROXIMITY SOUNDINGS FROM THE NAM
AND OPERATIONAL GFS SUGGEST CIN VALUES WILL BE A TOUCH HIGHER THE
FARTHER NORTH/NORTHEAST YOU GO ACROSS THE CWA. IN ADDITION...LOWER
TROPOSPHERIC CONVERGENCE AND LIFT WILL BE LOCALLY MAXIMIZED ACROSS
SOUTHWESTERN PORTIONS OF OUR CWA NEAR THE INTERSECTION OF THE LOWER
TROPOSPHERIC BAROCLINIC ZONE AND DRY LINE. THE CAP HAS BEEN TOO
STRONG TO ALLOW FOR MUCH IN THE WAY OF DEEP CONVECTION THE PAST
COUPLE DAYS...AND THE SAME SETUP EXISTS AGAIN TODAY. BUT DUE TO THE
LOCALLY ENHANCED LIFT NEAR THE INTERSECTION OF THE LOWER
TROPOSPHERIC BAROCLINIC ZONE AND DRY LINE NEAR OUR SOUTHWESTERN CWA
...WE CANNOT IGNORE THE POSSIBILITY OF A FEW ISOLATED STORMS
DEVELOPING AND AS A RESULT...WENT AHEAD WITH 20-30% POPS ACROSS OUR
SOUTHWEST CWA STARTING AT 22Z.

OMEGA SHOULD CONTINUE TO INCREASE ACROSS THE REGION
TONIGHT...ESPECIALLY ACROSS OUR NEBRASKA COUNTIES...AS THE
AFOREMENTIONED UPPER TROPOSPHERIC SHORT WAVE ADVANCES NORTHEAST FROM
COLORADO INTO NEBRASKA AND EVENTUALLY THE NORTHERN PLAINS. GIVEN
THIS...WENT AHEAD WITH AN INCREASING TREND IN POPS ACROSS OUR NORTH
00-12Z...WITH POPS THEN DIMINISHING THURSDAY MORNING. IT APPEARS
THERE WILL BE ONE MORE OPPORTUNITY FOR CONVECTIVE DEVELOPMENT ACROSS
EAST IN THE VICINITY OF THE LOWER TROPOSPHERIC BAROCLINIC ZONE
CLEARING THE AREA. GIVEN THIS...WENT AHEAD WITH ~30% POPS ACROSS OUR
EAST THURSDAY AFTERNOON AND EVENING.

SHOULD THUNDERSTORMS BE REALIZED ACROSS THE CWA THIS AFTERNOON AND
EVENING...0-1KM MLCAPE VALUES OF ~2000J/KG WILL LIKELY BE AVAILABLE
FOR UPDRAFT PRODUCTION...WITH DEEP LAYER BULK SHEAR OF AROUND 20KTS.
SO ALTHOUGH THE PROBABILITY OF ACHIEVING THUNDERSTORM DEVELOPMENT IS
RELATIVELY LOW...AND DEEP LAYER BULK SHEAR IS FAIRLY WEAK...THERE
WILL STILL BE A THREAT FOR LARGE HAIL AND STRONG THUNDERSTORM WIND
GUSTS. WILL GO AHEAD AND CONTINUE THIS MENTION FOR THE ENTIRE CWA IN
THE HWO. SHOULD THUNDERSTORMS BE REALIZED ACROSS OUR EAST THURSDAY
AFTERNOON AND EVENING...0-1KM MLCAPE VALUES OF 2000-3000J/KG WILL
LIKELY ACCOMPANY DEEP LAYER BULK SHEAR OF ~30KTS. GIVEN THIS...WILL
GO AHEAD AND OUTLOOK THE POSSIBILITY OF SEVERE WEATHER ACROSS OUR
EAST THURSDAY AFTERNOON AND EVENING.

A COOLER LOWER TROPOSPHERIC AIR MASS WILL PROMOTE COOLER OVERNIGHT
TEMPERATURE READINGS TONIGHT WHEN COMPARED TO EARLY THIS
MORNING...WITH LOWS IN THE 60S TO NEAR 70 CURRENTLY FORECAST. A
COOLER DAY IS ALSO ANTICIPATED THURSDAY WHEN COMPARED TO
WEDNESDAY...WITH HIGHS IN THE 80S EXPECTED FOR MOST PART ON
THURSDAY.

.LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 422 PM CDT WED JUN 18 2014

NO BIG CHANCES FROM PREVIOUS FORECAST FOR THIS 6-DAY PERIOD...AS
THERE CONTINUE TO BE A MULTITUDE OF CURRENTLY LESS THAN LIKELY
(LESS THAN 60 POPS) THUNDERSTORM CHANCES. IN FACT...11 OF THE 12
TWELVE-HOUR FORECAST PERIODS HERE FEATURE AT LEAST SLIGHT POPS
ACROSS SOME PORTION OF THE CWA...WITH THE SOLE EXCEPTION BEING
NEXT TUESDAY NIGHT...AT LEAST FOR NOW. ALTHOUGH STILL SUBJECT TO
PLENTY OF UNCERTAINTY...THE HIGHEST AND MOST WIDESPREAD COVERAGE
OF 40-50 POPS ARE CURRENTLY CONCENTRATED ON SATURDAY NIGHT AND
SUNDAY NIGHT-MONDAY DAYTIME...WITH SUNDAY NIGHT A POTENTIAL
CANDIDATE FOR A NEAR-FUTURE UPGRADE TO LIKELY POPS IF TRENDS HOLD.
AS FOR SEVERE WEATHER CHANCES...THERE ARE FORTUNATELY NO
PARTICULARLY-CONCERNING TIME FRAMES FOR HIGHER-END WIDESPREAD
SEVERE...BUT WILL PROBABLY HAVE TO WATCH SEVERAL PERIODS FOR AT
LEAST AN ISOLATED SEVERE THREAT...INCLUDING POTENTIALLY RIGHT AWAY
THURSDAY EVENING IN THE SOUTHEAST AS A CONTINUATION OF POSSIBLE
THURSDAY AFTERNOON CONVECTION DESCRIBED IN THE SHORT TERM
ABOVE...AND THEN FRIDAY AFTERNOON INTO FRIDAY NIGHT. ALTHOUGH WILL
SHY AWAY FROM EVEN MENTIONING MUCH IN THE WAY OF A SEVERE THREAT
BEYOND FRIDAY NIGHT DUE TO INHERENT UNCERTAINTY IN THE MESOSCALE
DETAILS...WOULD NOT BE SURPRISED TO SEE AT LEAST LOW-END SEVERE
PROBABILITIES (5-15 PERCENT) INTRODUCED IN UPCOMING STORM
PREDICTION CENTER OUTLOOKS FOR THE SATURDAY-MONDAY TIME FRAME.

BESIDES THUNDERSTORMS...THERE ARE CURRENTLY NO OTHER WEATHER
ELEMENTS FORECAST TO BREACH HAZARDOUS THRESHOLDS DURING THE LONG
TERM PERIOD...AS AT LEAST FOR NOW GRADIENT WIND SPEEDS ARE
FORECAST TO HOLD WELL-UNDER 30 MPH...AND HEAT INDEX VALUES ARE
FORECAST TO HOLD SAFELY BELOW 100 DEGREES.

SPEAKING OF HEAT...AND TURNING TO TEMPERATURES OVER THIS 6-DAY
PERIOD...THE OVERALL STORY STILL REMAINS THAT A VERY GRADUAL
COOLING TREND IS ANTICIPATED. MADE A FEW VERY SMALL UPWARD NUDGES
TO HIGHS MAINLY FRIDAY-SATURDAY (AND POTENTIALLY NOT
ENOUGH)...BUT HAVE HIGHS THESE DAYS GENERALLY UPPER 80S-LOWER 90S
MOST AREAS. SUNDAY IS THEN AIMED INTO MAINLY THE MID-UPPER 80S
RANGE FOR NOW...BEFORE A SLIGHTLY MORE NOTICEABLE DOWNTURN COMES
IN FOR MONDAY-WEDNESDAY WITH HIGHS GENERALLY RANGING LOW-80S NORTH
TO MD 80S SOUTH. OVERNIGHT LOWS THROUGH THE PERIOD ARE CURRENTLY
AIMED JUST SLIGHTLY ABOVE LATE-JUNE AVERAGES WITH MOST NIGHTS
AVERAGING SOMEWHERE IN/NEAR THE MID-60S.

TURNING TO A BIT MORE METEOROLOGICAL DETAIL AND TAKING IT IN
CHRONOLOGICAL BLOCKS...

THURSDAY EVENING/NIGHT STARTING AT 00Z/7PM...THE MAIN CHANGE FROM
PREV FCST HERE WAS THAT MENTIONABLE POPS WERE PULLED FROM THE LATE
NIGHT HOURS...AND EVEN DURING THE EVENING ONLY HAVE A FAIRLY
LIMITED AREA OF 20-30 POPS CONFINED TO SOUTHEAST ZONES...MAINLY
SOUTHEAST OF A HEBRON-STOCKTON LINE. IN THE MID-UPPER
LEVELS...RIGHT AWAY EARLY THURS EVENING A FAIRLY VIGOROUS
SHORTWAVE TROUGH WILL BE IN THE PROCESS OF DEPARTING EAST-
NORTHEAST OF THE LOCAL AREA ACROSS NORTHEAST NEB/DAKOTAS INTO MN.
MEANWHILE AT THE SURFACE...A WEAKENING COLD FRONT WILL BE IN THE
PROCESS OF SLOWING DOWN/STALLING OUT IN THE SOUTHEASTERN CWA. PER
THE SHORT TERM DISCUSSION ABOVE...AND ALSO MODEL DEPICTION SUCH AS
FROM THE GFS WITH UP TO AROUND 1500 J/KG MIXED LAYER CAPE IN THE
PRESENCE OF ONLY MODEST DEEP-LAYER SHEAR AROUND 30KT...CANNOT
COMPLETELY RULE OUT A LINGERING SEVERE STORM THREAT MAINLY RIGHT
AWAY IN THAT 7PM-10PM TIME FRAME IN THE AFOREMENTIONED FAR
SOUTHEAST. THAT BEING SAID...THE 12Z 4KM WRF-NMM/ARW SOLUTIONS ARE
FAIRLY INSISTENT THAT ALL STORM ACTIVITY SHOULD BE AT LEAST
SLIGHTLY SOUTHEAST OF THE CWA BY THE START OF THE THURSDAY EVENING
TIME FRAME. ALTHOUGH AM NOT SAYING THERE IS A ZERO CHANCE OF
LATER-NIGHT STORMS IN SOUTHERN ZONES AS SOME ELEVATED INSTABILITY
WILL LINGER...PROBABILITIES ARE TOO LOW TO MENTION AS THERE IS
LACK OF LARGE SCALE FORCING IN THE WAKE OF THE DEPARTING
SHORTWAVE...AND ALSO MEAGER LOW LEVEL JET SUPPORT. UPPED LOWS 2-3
DEGREES FROM PREV FCST...AIMING FOR A RANGE FROM NEAR-60 FAR
NORTHWEST TO UPPER 60S FAR SOUTHEAST.

FRIDAY-FRIDAY NIGHT...AS WAS THE CASE WITH LATE THURS
NIGHT...PULLED ANY MENTION OF SHOWERS/STORMS FROM THE MORNING
HOURS AS INSTABILITY-FORCING REMAINS FAIRLY LOW IN THE FACE OF
SUBTLE SHORTWAVE RIDGING. DID HOWEVER MAINTAIN SOME FAIRLY LOW-
CONFIDENCE 20-30 POPS FOR THE AFTERNOON AND OVERNIGHT HOURS AS THE
NEXT SUBTLE RIPPLES OF MID LEVEL ENERGY RIPPLE EASTWARD INTO THE
CENTRAL PLAINS IN SLOWLY-WEAKENING QUASI-ZONAL FLOW. ALTHOUGH
INSTABILITY IS SEASONABLY DECENT...DEEP LAYER WIND SHEAR LOOKS TO
STRUGGLE TO AVERAGE MORE THAN 20KT...SO ALTHOUGH SPC HAS BLANKETED
THE CWA WITH TOKEN 5 PERCENT SEVERE PROBS ON THE CURRENT DAY 3
OUTLOOK...JUST DON/T FORESEE A WIDESPREAD SEVERE THREAT.
FURTHERMORE...MODELS SUCH AS THE ECMWF/GFS STEER THE VAST MAJORITY
OF REGIONAL CONVECTION JUST OUTSIDE OF THE CWA TO THE WEST THROUGH
NORTH.

SATURDAY-SATURDAY NIGHT...THERE IS INCREASING CONFIDENCE THAT MOST
IF NOT THE ENTIRE DAY COULD REMAIN STORM-FREE BUT AT LEAST FOR NOW
LINGERED SOME TOKEN 20 POPS ALL AREAS BUT REDUCED SOME AREAS FROM
PREVIOUS 30S. THEN SATURDAY NIGHT...AT LEAST SOMEWHAT BETTER STORM
CHANCES ENTER THE PICTURE AS THE NEXT SOMEWHAT DECENT LOW
AMPLITUDE DISTURBANCE ENTERS THE PLAINS...ALTHOUGH POPS ARE ONLY
IN THE 40-50 RANGE FOR NOW.

SUNDAY DAYTIME THROUGH MONDAY DAYTIME...SOME OF THE OVERALL
HIGHEST-POPS OF THE LONG TERM CONTINUE DURING THIS 36-HOUR
PERIOD...BUT ESPECIALLY FOR SUNDAY NIGHT INTO MONDAY AS MODELS
SUCH AS THE 12Z ECMWF/GFS ARE IN RATHER GOOD AGREEMENT ON NOT ONLY
DROPPING A SOMEWHAT STRONGER MID LEVEL WAVE INTO THE REGION FROM
THE WEST-NORTHWEST...BUT ALSO BRINGING THROUGH A MODEST SURFACE
COLD FRONT AS WELL. ALMOST INTRODUCED LIKELY 60+ POPS TO THE
SUNDAY NIGHT PERIOD...BUT GIVEN THIS IS STILL SEVERAL DAYS AWAY
FELT IT MIGHT BE PRUDENT TO KEEP POPS CAPPED AT 40S-50S FOR AT
LEAST A SHORT WHILE LONGER PENDING MODEL TRENDS.

MONDAY NIGHT-TUESDAY NIGHT...THERE ARE INDICATIONS THAT MOST OF
THE CWA SHOULD STAY DRY THE MAJORITY OF THIS TIME IN THE WAKE OF
THE DEPARTING DISTURBANCE AND SUBSEQUENT WEAK PREVAILING
RIDGING...BUT AT LEAST FOR NOW WILL LET SOME TOKEN...MAINLY 20
SLIGHT POPS RIDE MON NIGHT-TUESDAY DAYTIME...WHILE LEAVING TUES
NIGHT VOID OF ANY STORM CHANCES AT THIS TIME.

FINALLY FOR WEDNESDAY DAYTIME...CONFIDENCE IS OBVIOUSLY QUITE LOW
AT THIS TIME RANGE...BUT PLAYED ALONG WITH OUR DEFAULT MULTI-MODEL
BLEND IN ADVERTISING SOME TOKEN SLIGHT SHOWER/STORM CHANCES IN
MOST AREAS.
