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 10, 3:12 PM CDT, 2 hours 42 minutes earlier.

Area forecast discussion, May 10, 3:12 PM CDT, 2 hours 42 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GOODLAND KS
212 PM MDT TUE MAY 10 2016

.SHORT TERM...(THIS AFTERNOON THROUGH WEDNESDAY)
ISSUED AT 159 PM MDT TUE MAY 10 2016

EARLY AFTERNOON WV IMAGERY AND RAP ANALYSIS SHOWS CLOSED UPPER LOW
CENTERED OVER EASTERN MONTANA WITH A SHORTWAVE RIDGE OVER EASTERN
KANSAS. SW FLOW IS IN PLACE ACROSS THE HIGH PLAINS WITH A SHORTWAVE
TROUGH MOVING INTO EASTERN COLORADO AROUND THE BASE OF THE UPPER
LOW. AT THE SURFACE...A PREFRONTAL TROUGH IS IN PLACE FROM JUST
ACROSS OUR EASTERN CWA...WITH A COLD FRONT MOVING INTO THE SNW HALF
OF THE CW (JUST NORTHWEST OF KMCK AND KGLD).

THIS AFTERNOON-TONIGHT...SHOWERS/THUNDERSTORM WILL DEVELOP ALONG AND
BEHIND SURFACE TROUGH AND COLD FRONT THIS AFTERNOON. COVERAGE WILL
INCREASE IN RESPONSE TO INCREASING LARGE SCALE FORCING LATE THIS
AFTERNOON THROUGH TONIGHT...WITH SUBSIDENCE SPREADING OVER THE
REGION FROM THE WEST BY 12Z TONIGHT. GUIDANCE CONTINUES TO SUPPORT
WIDESPREAD SHOWER/THUNDERSTORM COVERAGE BY THIS EVENING PARTICULARLY
IN OUR NORTH AND EAST...WITH MODERATE RAINFALL AMOUNTS. MEAN FLOW
WILL TEND TO BE PARALLEL TO FRONT AND POST FRONTAL ELEVATED
FRONTOGENESIS (850-700MB LAYER)...WHICH COULD SUPPORT TRAINING OF
SHOWER ACTIVITY AND LOCALLY HIGHER AMOUNTS.

REGARDING SEVERE THREAT...STRONG LINEAR/SPEED SHEAR IS IN PLACE AND
WILL CONTINUE THROUGH THIS EVENING RAISING THE POSSIBILITY FOR
ORGANIZED THUNDERSTORM CLUSTERS/MCS POTENTIAL. LIMITING FACTOR FOR
SEVERE AND LOCALLY HEAVY RAIN POTENTIAL IS LIMITED CAPE CURRENTLY
SHOW BY LATEST RAP ANALYSIS. GFS CURRENTLY REFLECTS CURRENT TRENDS
AND AT MOST HAS MU CAPE IN THE 500-900 J/KG RANGE BY LATE AFTERNOON.
NAM CONTINUES TO SHOW A NARROW AXIS OF HIGHER MU CAPE IN THE 900-
1500 J/KG RANGE IMMEDIATELY ALONG THE COLD FRONT LATE THIS
AFTERNOON/EVENING. AS THE NAM ALREADY SEEMS TO BE RUNNING HIGH ON
TDS THIS IS LIKELY INFLUENCING ITS CAPE PROFILES. IF GFS CONTINUES
TO VERIFY I AM SKEPTICAL THAT WE WOULD SEE MORE THAN SHOWERS AND
MARGINAL THUNDERSTORMS. WITH INVERTED V PROFILES ON MODEL SOUNDINGS
STRONG WINDS WILL BE A PRIMARY THREAT WITH STRONGER STORMS. IF
HIGHER CAPE (NAM) VERIFIES THEN WE MAY SEE AN ISOLATED QUARTER SIZE
HAIL THREAT.

WEDNESDAY...ANY LINGERING SHOWERS/THUNDERSTORMS IN THE MORNING
SHOULD END WITH A DRY PERIOD EXPECTED THROUGH MOST OF THE DAY UNTIL
THE AFTERNOON. ANOTHER SHORTWAVE TROUGH THEN ROTATES THROUGH THE
ROCKIES AND INTO THE SOUTHERN PLAINS. GUIDANCE IS SHOWING PRECIP
SIGNAL IN OUR SOUTHWEST BY THE LATE AFTERNOON...AND I STUCK WITH
PREVIOUS FORECAST TREND. BASED ON THE TRACK OF THIS SHORTWAVE AND
LIMITED INSTABILITY I AM NOT ANTICIPATING MUCH IN THE WAY OF
PRECIPITATION OUT OF THE ACTIVITY LATE WEDNESDAY AFTERNOON. POST
FRONTAL AIR MASS SHOULD BE SLIGHTLY BELOW NORMAL FOR HIGHS (MAINLY
IN THE MID-UPPER 60S).

.LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY)
ISSUED AT 211 PM MDT TUE MAY 10 2016

SHORTWAVE TROUGH EXITS THE REGION WEDNESDAY EVENING AND INTO
THURSDAY AS HIGH PRESSURE BUILDS SOUTHWEST OF THE CWA. THE RIDGE
REMAINS WEST OF THE REGION THROUGH SUNDAY BEFORE BREAKING DOWN AND
SLOWLY MOVING EAST. THE NEXT LOW PRESSURE SYSTEM WILL ROTATE IN FROM
THE WEST NORTHWEST LATE THIS WEEKEND AROUND A LARGE AREA OF LOW
PRESSURE SITUATED OVER THE GREAT LAKES REGION. WENT WITH DRY POPS
THURSDAY AFTERNOON THROUGH EARLY SATURDAY. THE BLEND GAVE 40 TO 50
PERCENT POPS SATURDAY AFTERNOON INTO SUNDAY HOWEVER THERE WILL BE
SOME SUBSIDENCE TO OVERCOME AS THE RIDGE RETREATS EASTWARD THUS I
REDUCED POPS SLIGHTLY DURING THIS TIME FRAME. FOR SUNDAY AFTERNOON
INTO MONDAY...POPS REMAIN IN THE 30 TO 40 PERCENT RANGE AS THE LOW
MOVES OVER THE CWA AND WEAKENS AS IT MOVES TO THE EAST AND
SOUTHEAST.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z WEDNESDAY AFTERNOON)
ISSUED AT 1136 AM MDT TUE MAY 10 2016

VFR CONDITIONS SHOULD PREVAIL THROUGH THE TAF PERIOD AT BOTH KGLD
AND KMCK TERMINALS. SHOWERS AND THUNDERSTORMS WILL OVERSPREAD
BOTH TERMINALS ALONG AND BEHIND A COLD FRONT THIS AFTERNOON
THROUGH THE OVERNIGHT...AND BRIEF DROPS TO MVFR CIG/VIS CANT BE
RULED OUT WITH STRONGER STORMS/HEAVIER SHOWERS. NOT ENOUGH
CONFIDENCE TO INTRODUCE SUB VFR CONDITIONS AT THIS POINT. MAIN
CHANGE WAS TO FINE TUNE TIMING OF SHOWERS/THUNDERSTORMS BASED ON
LATEST SHORT RANGE GUIDANCE AT BOTH TAF SITES...ALONG WITH
INCREASE IN WINDS AS FRONT MOVES ACROSS REGION LATE THIS AFTERNOON
INTO THIS EVENING.
