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 Omaha, NE wrote its last area forecast discussion before this severe thunderstorm warning went out at May 19, 9:52 PM CDT, 1 hour 7 minutes earlier.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
952 PM CDT THU MAY 19 2011

.UPDATE...

UPDATED TO ADD SOME TIMING TO THE OVERNIGHT POPS AND TO LOWER
OVERNIGHT TEMPS.

&&

.DISCUSSION...

GOING FORECAST IN PRETTY GOOD SHAPE TONIGHT. SHOWERS AND
THUNDERSTORMS HAVE INCREASE IN COVERAGE OVER THE AREA EARLIER THIS
EVENING AS STRONG UPPER LEVEL JETLET ROTATING NORTHEAST INTO THE
HIGH PLAINS. THIS ACTIVITY SHOULD CONTINUE FOR A GOOD PART OF THE
NIGHT NOW THAT THE LOW-LEVEL JET IS INCREASING ACROSS KS AND INTO
SOUTHERN NEB PER AREA VAD AND WIND PROFILERS. AS COMMENTED ON THE
LAST COUPLE OF DAYS...THE VERY SUBSTANDARD LAPSE RATES HAS LED TO
ONLY MARGINAL INSTABILITY AND THIS FOR THE MOST PART IS KEEPING
STORMS IN CHECK DESPITE GOOD QUALITY MOISTURE AND SHEAR. WE EXPECT
THIS TREND TO CONTINUE OVERNIGHT WITH A VERY LIMITED SEVERE
WEATHER THREAT. OTHERWISE WITH PWATS OF 1.50 TO 1.75 INCHES FROM
KANSAS INTO EASTERN NEBRASKA...HEAVY RAIN MAY BE MORE OF A THREAT
OVERNIGHT WITH A GOOD 1 TO 2 INCHES OF RAIN LIKELY. GOING FORECAST
HAD A HEAVY RAIN MENTION AND SO NO CHANGES THERE. DID REDUCE
EVENING POPS EARLIER IN SOUTHWEST IOWA AS STORMS WILL LIKELY NOT
MAKE IT OVER THERE UNTIL AFTER 10 PM. OTHERWISE GOING TEMPS ARE
NEAR OVERNIGHT LOWS AND THUS HAVE LOWERED A TOUCH ALTHOUGH WITH
WAA SHOULD KEEP TEMPS FROM REALLY FALLING TO MUCH MORE. ALL
UPDATES HAVE BEEN SENT.

SHORT TERM...TODAY THROUGH SATURDAY NIGHT.

HIRES WRF-NMM/RUC13/GFSLAMP ALL IN GOOD AGREEMENT SHOWING PROBABILITY
OF CONVECTIVE REDEVELOPING HIGH TONIGHT ALONG A SLOW LIFTING WARM

OMEGA FIELDS PER BOTH NAM/GFS BULLS-EYE THE CWA...THUS HAVE DECIDED
TO BUMP POPS TO 90% AND INCREASE 6HR QPF AMOUNTS. HEAVY RAIN A
DEFINITE POSSIBILITY IN SOME LOCATIONS OVERNIGHT. GIVEN JUST
COMBINATION OF DEEP SHEAR/MUCAPE SVR POTENTIAL LOOKS PROMISING
TONIGHT AHEAD/ALONG SLOW LIFTING WARM FRONT...MAINLY FOR THE SRN CWA.
POTENTIAL FOR SVR DEVELOPMENT AS WELL FRIDAY AFTN...BUT THINK MAIN
THREAT WILL BE FOUND FARTHER SOUTH. MEANWHILE SFC BNDRY BECOMING
ESTABLISHED ALONG THE WRN HIGH PLAINS BEFORE SWEEPING EAST ON
SATURDAY. LLVL MOIST/UNSTABLE AIRMASS WORKING ITS WAY NWD AHEAD OF
APPROACHING COLD FRONT WILL LIKELY RESULT IN CONVECTIVE REDEVELOPMENT
SAT AFTN.

LONG TERM...SUNDAY THROUGH THURSDAY.

OVERALL NO MAJOR CHANGES MADE AND HAVE KEPT SMALL POPS IN PLACE

COMPLICATED HAVE GENERALLY FOLLOWED ALONG WITH HPC. PCPN CHANCES
ESSENTIALLY FOCUSED AROUND WEAKENING UPPER CLOSED LOW MIGRATING
ACROSS THE NRN PLAINS/UPPER MIDWEST DRAGGING A CANADIAN AIRMASS INTO
THE LOWER 48. BOTH GFS/ECM DO AGREE THIS AIRMASS WILL PENETRATE QUITE
FAR TO THE SOUTH AND IS PROGGED TO EXTEND FROM THE SRN PLAINS TO THE

HIGHS ABOUT 10 DEGREES BELOW NORMAL.

CIG BEFORE 00Z. MVFR CONDITIONS ARE EXPECTED FOR THE REST OF THE TAF
PERIOD THROUGH FRIDAY MORNING AS MOISTURE CONTINUES TO PUSH

DEVELOPING IN THE HIGH PLAINS DURING THE AFTERNOON AND EVENING WILL
EVENTUALLY PUSH NORTHEAST INTO EASTERN NEBRASKA BY 06Z. IFR
