The radar

The Grand Island radar (KUEX), 136 km from the middle of the area, began a volume at 05:04 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

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.

The nearest sounding before it

N. Platte/Lee Bi, NE (KLBF), launched 00:00Z, 5.0 hours before the alert went out and 177 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Goodland, KS wrote its last area forecast discussion before this severe thunderstorm warning went out at May 15, 9:38 PM CDT, 2 hours 23 minutes earlier.

Area forecast discussion, May 15, 9:38 PM CDT, 2 hours 23 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
838 PM MDT FRI MAY 15 2015

.UPDATE...
ISSUED AT 836 PM MDT FRI MAY 15 2015

UPDATED FORECAST TO INCLUDE MENTION OF AN AREA OF RAIN SHOWERS AND
ISOLATED THUNDERSTORMS FOR THIS EVENING. RADAR TRENDS SHOW AN AREA
OF MOSTLY LIGHT RAINSHOWERS MOVING NORTHEAST INTO WALLACE AND
LOGAN COUNTIES WHICH WILL LIKELY CONTINUE NORTHEAST FOR A FEW MORE
HOURS.

&&

.SHORT TERM...(THIS EVENING THROUGH SATURDAY)
ISSUED AT 1255 PM MDT FRI MAY 15 2015

MAIN FORECAST CONCERNS WILL CENTER AROUND LOCATION...INTENSITY AND
TIMING OF THUNDERSTORMS OVER THE NEXT 2 DAYS AS LARGE TROUGH TO
THE WEST KEEPS CWA IN ACTIVE PATTERN THROUGH SATURDAY.

19Z SURFACE ANALYSIS INDICATED SFC LOW/TROUGH DEVELOPING ACROSS
EASTERN COLORADO WITH LOWEST PRESSURES NEAR KLHX. DRYLINE IS
BEGINNING TO SHOW ITSELF TO THE SOUTHWEST OF CWA WITH AREA OF CU
NEAR KTRB LIKELY INDICATING LEADING EDGE. WEAK TROUGH/OUTFLOW
BOUNDARY NOTED FROM ROUGHLY ATWOOD TO HYS WITH AREA OF FAIRLY FLAT
CU FORMING ALONG IT.

CONVECTIVE INITIATION AND RESULTING MOVEMENT IS INITIAL CONCERN
AS BOTH DRYLINE/TROUGH WILL BE POSSIBLE AREAS FOR THUNDERSTORM
DEVELOPMENT...WITH BULK OF CAM MODELS SUGGESTING EASTERN COLORADO
IN VICINITY OF TROUGH BEING MOST LIKELY AREA. DEEP LAYER SHEAR
PROFILES AND INSTABILITY SUPPORT ORGANIZED/SUPERCELLULAR STORMS
AND THINK THREAT FOR SEVERE WEATHER WILL CONTINUE INTO THE
EVENING. AT THIS TIME LCL/LOW LEVEL SHEAR VALUES ARE MAXIMIZED TO
THE NORTH OF THE CWA WITH ONLY YUMA AND DUNDY COUNTY APPROACHING A
MORE FAVORABLE TORNADO ENVIRONMENT. LOW LEVEL CONVERGENCE WILL
GRADUALLY SHIFT TO THE EAST AS LOW LEVEL JET STRENGTHENS TO
AROUND 50 KTS AND ANTICIPATE PRECIPITATION AREA TO SHIFT TO THE
EAST AS WELL.

ON SATURDAY...LARGE SCALE FORCING FOR ASCENT WILL OVERSPREAD THE
AREA DURING THE MORNING HOURS AS STRONG COLD AIR ADVECTION
ASSOCIATED WITH THE TROUGH DESTABILIZES THINGS FAIRLY QUICKLY.
WHILE THERE MAY BE SOME RECOVERY NEEDED DUE TO OVERNIGHT
THUNDERSTORMS...THINK LARGE SCALE FORCING AND LARGE SCALE
DESTABILIZATION DUE TO TROUGH WILL PROMOTE AN EARLIER INITIATION
OF CONVECTION THAN RECENT DAYS. WITH FLOW ALOFT INCREASING...SHEAR
AND STORM RELATIVE FLOW VECTORS SUPPORT A PATTERN ACROSS THE AREA
MORE FAVORABLE FOR LONGER DURATION SUPERCELLS AND POSSIBLY
TORNADIC STORMS. LOCATION AND STORM MODE WILL GREATLY RELY ON HOW
EARLY STORMS DEVELOP AND WHERE DRYLINE BECOMES BETTER DEFINED IN
THE AFTERNOON.

.LONG TERM...(SATURDAY NIGHT THROUGH FRIDAY)
ISSUED AT 151 PM MDT FRI MAY 15 2015

THE LONG TERM PERIOD BEGINS WITH A NEGATIVELY TILTED TROUGH THAT
WILL BRING SHOWERS AND THUNDERSTORMS TO THE TRI STATE AREA.  MOST OF
THE SEVERE ACTIVITY WILL OCCUR SATURDAY AFTERNOON...BUT SOME SEVERE
THUNDERSTORMS MAY LINGER EAST OF HIGHWAY 83 EAST OF A SURFACE
DRYLINE. THE UPPER LEVEL TROUGH BASE WILL PUSH THROUGH THE AREA
OVERNIGHT...AND SHOWERS AND THUNDERSTORMS WILL TAPER OFF AT THIS
TIME AS THE SURFACE COLD FRONT MOVES THROUGH OVERNIGHT SATURDAY INTO
SUNDAY MORNING.

SUNDAY WILL REMAIN DRY WITH SLIGHT CHANCES FOR SHOWERS AND
THUNDERSTORMS IN EASTERN COLORADO AS A SURFACE COLD FRONT PUSHES
INTO THE HIGH PLAINS.  LIMITED CAPE AND MARGINAL 0-6 KM BULK SHEAR
IN THE ATMOSPHERIC PROFILE SHOULD NOT ALLOW FOR WIDESPREAD SEVERE
WEATHER...BUT SOME GENERAL THUNDERSTORM DEVELOPMENT IS POSSIBLE.
ONCE THE SURFACE COLD FRONT PASSES...MONDAY WILL BE COOLER AND DRY
WITH A SURFACE HIGH PRESSURE SYSTEM MOVING INTO THE TRI STATE AREA.

ALTHOUGH MODEL FORECASTS DIFFER ON LOCATIONS A BIT...TIMING OF A
VERY NEGATIVELY TILTED UPPER TROUGH LOOKS TO BE IN AGREEMENT FOR A
TUESDAY ARRIVAL. A STRONGER 50-60 KT JET ROUNDING THE BASE OF THE
TROUGH AROUND THE BAJA PENINSULA WILL TAP INTO GOOD MOISTURE AND
ADVECT SATURATED AIR INTO THE HIGH PLAINS. GFS MODEL SOUNDINGS SHOW
A MAJORITY OF LOCATIONS WITH SATURATED PROFILES WITH STRONG SOUTH TO
SOUTHEASTERLY ADVECTION TO ACROSS THE FORECAST AREA TUESDAY WITH
PWAT VALUES BETWEEN THE 75TH AND APPROACHING THE 99TH PERCENTILE FOR
CLIMATOLOGY WITH VALUES BETWEEN 0.75 TO OVER ONE INCH. WITH SOME
SMALL AMOUNTS OF CAPE IN THE PROFILE BETWEEN 100 AND 200 J/KG...THE
POSSIBILITY OF WIDESPREAD MODERATE RAINFALL IS POSSIBLE.

THE UPPER TROUGH BEGINS TO BREAK DOWN ACROSS THE AREA
WEDNESDAY...HOWEVER LINGERING REMNANTS OF LIFT WILL BRING MORE
CHANCES FOR SHOWERS AND THUNDERSTORMS.  MOST LOCATIONS WILL
EXPERIENCE LITTLE CAPE WITH GFS MODEL SOUNDINGS INDICATING BETWEEN
400 AND 800 J/KG...BUT NOT EXACTLY SURE THIS ENERGY WILL BE REALIZED
IF A BROKEN OR OVERCAST LAYER WILL KEEP A STEADY CAP IN PLACE.  THE
ONLY LOCATION WITH ABOVE 1000 J/KG AND 0-6 KM BULK SHEAR ABOVE 60
KTS IS WEST CENTRAL KANSAS...BUT THE ECMWF DOES NOT HAVE ANY
SIGNIFICANT CAPE.  THEREFORE...SEVERE THREAT IS UNLIKELY BUT
POSSIBLE FOR SOME ISOLATED LOCATIONS WEDNESDAY.

SOLUTIONS DIVERGE FOR THURSDAY WITH SOME MODELS INDICATING A
SHORTWAVE RIDGE BUILDING...BUT A SHORTWAVE TROUGH LOOKS TO BE
POSSIBLE TOO.  STUCK WITH BLEND OF MODELS TO PLACE CHANCES FOR
SHOWERS AND THUNDERSTORMS.

BECAUSE OF THE MOIST PATTERN WITH MOSTLY CLOUDY SKIES NEXT
WEEK...EXPECTING HIGH TEMPERATURES NEXT WEEK TO BE ABOUT 10 DEGREES
COOLER THAN NORMAL WITH HIGHS IN THE LOW TO MID 60S. LOW
TEMPERATURES SHOULD BE ABOUT NORMAL.

&&

.AVIATION...(FOR THE TAFS 00Z SATURDAY THROUGH 00Z SUNDAY)
ISSUED AT 815 PM MDT FRI MAY 15 2015

UPDATED KGLD TAF TO REFLECT WINDSHIFT WITH PASSAGE OF OUTFLOW
BOUNDARY AND ALSO MENTION A COUPLE HOURS OF LIGHT RAIN FROM 03-05Z
GIVEN CURRENT RADAR TRENDS.  UPDATED KMCK TAF TO REMOVE MENTION OF
THUNDER AND ALSO INTRODUCE A WIND SHIFT AND CHANCE FOR LIGHT RAIN
SHOWERS AFTER 05Z.

PREVIOUS DISCUSSION...SURFACE LOW OVER COLORADO WILL MAINTAIN STRONG
SOUTHERLY WINDS THROUGH THE PERIOD...WITH WINDS DIMINISHING SOMEWHAT
TONIGHT. VFR CONDITIONS WILL PREVAIL WITH A SMALL CHANCE FOR A
SHOWER OR THUNDERSTORM VICINITY OF THE TERMINALS THIS EVENING.
SATURDAY AFTERNOON THERE IS POTENTIAL FOR STRONG THUNDERSTORMS TO
DEVELOP AFTER 18-20Z...WITH BETTER CHANCES AT KMCK COMPARED TO KGLD.
WINDS SATURDAY WILL BE SOUTHERLY GUSTING OVER 30 KTS AT BOTH
TERMINALS.
