What happened

The episode as NWS GID wrote it up.

A strong thunderstorm produced hail to the size of nickels in far southern Osborne County (north of Luray) very early on this Friday morning. Several small thunderstorms initiated around midnight over Ellis County and quickly merged as they lifted northeast. Over the following two hours, other storms initiated over north central Kansas, forming a northwest-southeast oriented line. One storm embedded within the line was strong enough to produce this nickel size hail.

A weak low pressure system was advancing through the Northern Plains. Low pressure was over Minnesota, with the associated cold front extending southwest across Nebraska into Wyoming. These storms formed in the warm sector, well ahead of the front. In the upper-levels, a longwave trough was over the western United States, with a ridge over the East. These storms developed just after the passage of a shortwave ridge. Synoptic forcing was negligible. While the strongest warm air advection was further north over Nebraska, these storms did initiate near the nose of a 30-40 knot low-level jet. MUCAPE was around 1000 J/kg and deep layer shear was around 20 knots.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
1234 AM CDT FRI MAY 15 2015

.SHORT TERM...(THIS EVENING THROUGH FRIDAY)
ISSUED AT 343 PM CDT THU MAY 14 2015

SEEING DRY CONDITIONS ACROSS THE AREA THIS AFTERNOON...AS UPPER
LEVEL SHORTWAVE RIDGING SLIDES THROUGH THE PLAINS...SET UP BETWEEN
ONE DISTURBANCE MOVING INTO THE GREAT LAKES/MIDWEST...AND LOW
PRESSURE MOVING ONTO THE WEST COAST. A WEAKER PATTERN IS IN PLACE
AT THE SFC...LOW PRESSURE OVER SD BRINGING W/SWRLY WINDS TO THE
CWA...WITH SPEEDS GENERALLY AROUND 10 MPH. LOW LEVEL STRATUS IS
TAKING ITS TIME DIMINISHING FROM WEST/EAST...LXN IS SITTING IN THE
LOW 70S...YORK IN THE MID 60S.

THIS EVENING AND TONIGHT...THUNDERSTORM CHANCES REMAIN IN THE
FORECAST. MODELS ARE IN PRETTY GOOD AGREEMENT SHOWING THE
SHORTWAVE RIDGING CONTINUING TO PUSH THROUGH/OUT OF THE
AREA...WITH A WEAK WAVE MOVING IN FROM THE SW. SFC LOW PRESSURE IS
EXPECTED TO DEEPEN OVER E/NE CO OVERNIGHT...WITH A WARM FRONTAL
BOUNDARY DEVELOPING/EXTENDING EAST ACROSS THE SRN HALF OF THE CWA.
ALONG WITH INCREASED WARM AIR/MOISTURE ADVECTION VIA A S/SWRLY
LLJ...THUNDERSTORMS ARE EXPECTED TO AFFECT PORTIONS OF THE AREA.
WITH TIME...THIS FRONT AND ACCOMPANYING ACTIVITY IS EXPECTED TO
SHIFT NORTH. DIDNT MAKE ANY SIGNIFICANT CHANGES TO POPS...WITH
MODELS CONTINUING TO SHOW OVERALL COVERAGE BEING MORE SCATTERED IN
NATURE. STILL THINKING THAT STRONG THUNDERSTORMS ARE POSSIBLE
GIVEN THE MODEL INSTABILITY...THOUGH DEEP LAYER SHEAR IS ON THE
WEAKER SIDE.

INTO TOMORROW/TOMORROW NIGHT...WHATEVER ACTIVITY ONGOING FROM
TONIGHT LOOK TO CONTINUE PUSHING NORTH THROUGH THE CWA. SHOULD SEE
A LULL DURING THE LATER MORNING/EARLY AFTERNOON PERIOD...WITH
ADDITIONAL THUNDERSTORM CHANCES MID/LATE AFTERNOON...DRIVEN BY
ANOTHER SHORTWAVE DISTURBANCE EJECTED OUT AHEAD OF THE MAIN UPPER
LEVEL LOW /WHICH CONTINUES TO SLIDE IN FROM THE WEST COAST/. AT
THE SFC...COMPARED TO YESTERDAY WHICH HAD THE MAIN WARM FRONT
THROUGH THE HEART OF THE CWA...THIS MORNINGS RUN SHOWED A
NORTHWARD SHIFT TO ITS LOCATION. THE MAIN SFC LOW IS EXPECTED TO
BE OVER FAR SWRN NEB/NERN CO BY LATE AFTERNOON...WITH THE WARM
FRONT MORE ACROSS NRN NEB. A DRYLINE WILL BE BECOMING MORE WELL
DEFINED WITH TIME DURING THE DAY...AND BY LATE AFTERNOON LOOKS TO
BE MAKING A PUSH INTO SWRN PORTIONS OF THE CWA. SITTING IN THE
WARM SECTOR...HAVE FORECAST HIGHS IN THE UPPER 70S/LOWER
80S...WITH DEWPOINTS CLIMBING INTO THE 60S. THE PROXIMITY TO THE
SFC LOW LOOKS TO BRING GUSTY S/SE WINDS...WITH SPEEDS IN THE 20 TO
25 MPH RANGE.

AS THAT UPPER LEVEL DISTURBANCE MOVES INTO THE AREA...THIS DRY
LINE IS EXPECTED TO BE THE FOCUS FOR THUNDERSTORMS...THOUGH THE
LATEST RUN OF MODELS PUTS THE OVERALL COVERAGE INTO QUESTION.
WHILE OVERALL FORCING ISNT AS STRONG AS
SATURDAY...INSTABILITY/SHEAR PARAMETERS ARE MORE THAN SUFFICIENT
FOR THUNDERSTORMS TO BECOME SEVERE...SHOULD THEY FORM. NO CHANGES
WILL BE MADE TO THE HWO. THE 12/18Z NAM...12Z 4KM WRF ARE A COUPLE
THAT ARE SHOWING THUNDERSTORMS TO BE MORE ISOLATED/SCATTERED IN
NATURE...SO AGAIN DIDNT MAKE ANY NOTABLE CHANGES TO POPS. THESE
MODELS ALSO SHOW WHATEVER DOES FORM NOT LASTING LONG INTO THE
OVERNIGHT PERIOD...WITH FOCUS TURNING TO THE POST MIDNIGHT
HOURS...AS LARGE SCALE LIFT CONTINUES TO INCREASE AHEAD OF THE
MAIN LOW/INCREASED JET ENERGY...POTENTIALLY BRINGING IN ANOTHER
AREA OF PRECIPITATION IN FROM THE S/SW.

.LONG TERM...(FRIDAY NIGHT THROUGH THURSDAY)
ISSUED AT 343 PM CDT THU MAY 14 2015

AN UPPER LEVEL WAVE WILL MOVE THROUGH THE AREA SATURDAY MORNING.
EXPECT THUNDERSTORMS TO DEVELOP AS THIS WAVE MOVES INTO THE
AREA. THE BEST CHANCE FOR THUNDERSTORMS WILL BE IN THE SOUTHEAST
PART OF THE FORECAST AREA. THEN DURING THE AFTERNOON AN UPPER LOW
MOVES OUT OF THE ROCKIES INTO THE CENTRAL PLAINS. THERE IS A
SURFACE LOW AND FRONT TO THE WEST OF THE FORECAST AREA. THERE IS
ALSO A DRY LINE TO THE SOUTH OF THE LOW PRESSURE SYSTEM. THERE IS
MUCAPE OF 1500 TO 2000 J/KG DURING THE AFTERNOON INTO THE EVENING.
ALL THIS BEING SAID...WITH THE THUNDERSTORMS IN THE MORNING THERE
ARE A FEW EXTRA QUESTIONS FOR THE CONVECTION IN THE AFTERNOON.
WILL THERE BE ENOUGH INSTABILITY TO GET SEVERE WEATHER? WILL THERE
BE ANY EXTRA BOUNDARIES AROUND DURING THE AFTERNOON? STILL EXPECT
THERE TO BE SEVERE WEATHER.

THE UPPER LEVEL LOW MOVES TO THE NORTHEAST ON SUNDAY. THE
THUNDERSTORMS FROM SATURDAY NIGHT WILL LINGER IN THE NORTHERN PART
OF THE FORECAST AREA DURING THE DAY...BUT SHOULD BE GRADUALLY
COMING TO AN END.

A SURFACE HIGH NOSES INTO THE FORECAST AREA SUNDAY NIGHT AND
CONTINUES TO AFFECT THE AREA THROUGH MONDAY NIGHT. TEMPERATURES
WILL BE A LITTLE COOLER AS WELL.

ON TUESDAY THE NEXT UPPER LEVEL LOW IS DEVELOPING IN THE ROCKIES
AND SENDS A WAVE INTO THE AREA. THIS WILL BRING THUNDERSTORMS
BACK TO THE AREA...MAINLY IN THE WEST...ON TUESDAY. THE UPPER
LEVEL LOW MOVES THROUGH THE AREA TUESDAY NIGHT THROUGH WEDNESDAY
NIGHT. THE PRECIPITATION SPREADS ACROSS THE AREA TUESDAY NIGHT AND
WEDNESDAY. BY TUESDAY NIGHT AND WEDNESDAY THERE IS LITTLE CAPE AND
THERE EXPECT ONLY ISOLATED THUNDERSTORMS. THIS IS WHERE THE MODELS
START TO HAVE SOME DIFFERENCES. THE GFS CONTINUES TO HAVE SOME
PRECIPITATION ACROSS THE AREA WEDNESDAY NIGHT AND EVEN INTO
THURSDAY BUT THE ECMWF IS DRY. HAVE KEPT SOME LOW POPS ACROSS THE
AREA...BUT WILL HAVE TO WATCH TO SEE IF THE MODELS CONTINUE TO BE
DRY.

.AVIATION...(FOR THE 06Z KGRI/KEAR TAFS THROUGH 06Z FRIDAY NIGHT)
ISSUED AT 1224 AM CDT FRI MAY 15 2015

THE MAIN FOCUS FOR THE TAF PERIOD IS TIMING OF CONVECTION THRU THE
TAF PERIOD. SHORT TERM MODELS SUGGEST AN INITIAL ROUND OF STORMS
MAY ARRIVE TOWARD DAYBREAK...THEN REDEVELOP AGAIN AS A WARM
FRONTAL BOUNDARY LIFTS NORTH THIS AFTN. HAVE COVERED TSTM
POTENTIAL WITH A VCTS FOR NOW AND WILL MONITOR HOW THINGS DEVELOP.
WINDS WILL PRIMARILY BE FROM A SOUTHEASTERLY DIRECTION AND WILL BE
GUSTY AT TIMES DURING THE AFTN. CIGS SHLD PRIMARILY BE AT VFR BUT
MAY LOWER TO MVFR AT TIMES IN THE LATTER TAF HOURS.
