.DISCUSSION...

SYNOPSIS...00Z UPPR AIR ANLYS INDCD MAIN UPPR LVL LO WAS NOW
LOCATED OVR FAR ERN CO. A NUMBER OF SHRTWV TROFS/PV ANOMALIES WERE
VISIBLE ROTATING ARND THE UPPR LVL LOW. THE FIRST AT 00Z WAS
LOCATED OVR NRN OK. UPSTREAM FM THIS WAVE A VERY POTENT UPPR LVL
WAVE OVR NRN MEXICO ASSOCIATED WITH A 120 KT H3 JET. AT H85...A
FAIRLY BROAD MOIST SECTOR WITH DEW POINTS OF 10 OR GREATER EXTNDD
FM THE LO MS RVR VALLEY INTO THE MID MO RVR VALLEY. 08Z SFC ANLYS
INDCD LO PRES OVR SW KS WITH AN INVERTED TROF NWD THRU CNTRL NEB
AND AN ILL DEFINED WRM FNT NEWD FM LO THRU ERN NEB INTO SRN IA.

FORECAST...DIFFICULT AND RATHER TRICKY FORECAST FOR TODAY...AND AS
WITH YESTERDAY...MAIN CONCERN DURING THE FIRST 12 HOURS WILL BE
SEVERE WEATHER. GOOD DEAL OF CONFIDENCE THOUGH IN THE FIRST 6
HOURS OF THE DAY. OKLAHOMA SHRTWV TROF NOW MOVG THRU NE KS AND
THIS MRNG HAS ALLOWED MOST OF THE SHOWER AND STORMS TO SHIFT E
AND N OF OUR FA. LARGER-SCALE SUPPORT OVR THE NW FA WL CONT TO
PROVIDE THAT AREA WITH SHOWERS THRU THE MRNG...AND WL CONT WITH
SOME LIKELY POPS IN THAT AREA. OTHERWISE...DRYING SHLD CONT OVR
THE CNTRL/ERN CWA AS THE LO LVL JET VEERS AND THE MOIST AXIS
SHIFTS EWD. THUS SHLD START THE DAY...GENERALLY E OF HIGHWAY 81
WITH MOSTLY SUNNY SKIES. PREVIOUSLY MENTIONED POTENT UPPR LVL
SHRTWV TROF OVR NRN MEXICO AT 00Z THIS EVNG...WL QUICKLY EJECT
NEWD THIS MRNG AND ALLOW FOR SIG CYCLONGENESIS OVR THE SRN PLAINS.
THIS LO PRES AREA WL CONT TO DEEPEN AND LIFT INTO THE MID MS RIVER
VALLEY REGION TODAY BECOMING THE MORE DOMINATE SFC LO.
NEVERTHELESS...AREA OF LO PRES OVR SW KS EARLY THIS MRNG WL TRACK
EWD TODAY WHILE FILLING. INVERTED TROF WL ALSO BE MOVG EWD TODAY
AND INTO THE CNTRL CWA BE MID AFTN. STEEPER MID LVL LAPSE RATES
SEEN ON THE 00Z H7 ANALYSIS UPSTREAM WL BE LOCATED OVR THE
CNTRL/ERN CWA BY AFTN...AND THIS SHOULD COMBINE WITH RESIDUAL LO
LVL MOISTURE TO PRODUCE SFC BASED CAPE VALUES OF 800-1000 J/KG BY
EARLY AFTN AHEAD OF THE INVERTED TROF. LITTLE IF ANY CAP WL BE
PRESENT TODAY DUE TO COLD MID LVL TEMPS...AND THUS CONVECTIVE
INITIATION SHLD TAKE PLACE BY EARLY AFTN OVR THE ERN/SRN CWA. THE
SHEAR SIGNIFICANTLY WEAKENS TODAY AS BETTER MID LVL FLOW SHIFTS E
AND S OF THE FA...AND THIS MAKES STORM MODE AND ANY THREATS MORE
DIFFICULT TO DETERMINE ATTM. WITH THE FREEZING LVL RUNNING AROUND
8 K FT...WE FEEL THAT HAIL WILL BE VERY COMMON WITH ANY STORM THAT
FORMS...AND SVR HAIL SEEMS POSSIBLE GIVEN THE AMOUNTS OF CAPE AND
COLD ATMOSPHERE.

THERE WILL ALSO BE LO LVL AMBIENT VORTICITY ARND UNDER THE UPPR
LVL LO AND NEAR THE SFC LO. AS TEMPERATURES QUICKLY WARM THIS
MRNG...0 TO 2 KM LAPSE RATES OF 8-9 C/KM SEEM LIKELY LEADING TO
SOME 0 TO 3 KM CAPE. WLD BE A LITTLE CONCERNED ABOUT NON-SUPERCELL
TORS ALNG THE INVERTED TROF TODAY...BUT TROF SHLD HAVE SOME FWD
MOVEMENT...AND DEEPER MOISTURE WL BE LOCATED FARTHER E...BUT THIS
WL HAVE TO BE WATCHED CLOSELY. TOR THREAT GENERALLY SEEMS PRETTY
LO IN THE ERN FA WHERE THE DEEPER MOISTURE RESIDES WITH A LACK OF
ANY SYNOPTIC BOUNDARIES AND VERY WEAK LO LVL SHEAR...BUT GIVEN
THE LO LVL AMBIENT VORTICITY AND CAPE...STRETCHING OF THIS CAPE
NEAR ANY RESIDUAL OUTFLOW BOUNDARY CLD BE VERY IMPORTANT AND WL
ALSO HAVE TO BE WATCHED. ANY STORMS SHLD QUICKLY COME TO AND END
BY LATE AFTN/EARLY EVNG AS BOUNDARY LAYER STABILIZES. WITH MAIN
Q-G FORCING AND MOISTURE SHIFTING S AND E OF THE FA...HAVE STARTED
TRIMMING POPS A LITTLE EARLIER TONIGHT AND INTO THE DAY ON SUN. AS
FAR AS TMPS...DID BUMP UP TEMPS TODAY DUE TO THE SUNNY START. ALSO
WARMED THINGS A TOUCH OVERNIGHT WITH THE MIXING EXPECTED BEHIND
THE INVERTED TROF.

REST OF THE FORECAST FOR THE MOST PARTK UNCHANGED. NEXT SYSTEM WL
QUICKLY MOV INTO THE AREA ON SUN NIGHT AND INTO THE DAY ON MON.
STG GET AND ASSOCIATED FORCING WL MOV INTO THE NRN PLAINS...BUT
MUCH OF THE FORCING LOOKS TO STAY N OF THE FA WITH OUR BEST CHCS
IN OUR N AND NE FOR SHOWERS ON MONDAY. DID LOWER HIGHS ON MON/TUES
WITH SOME PRETTY CHILLY AIR ALOFT OVER THE REGION.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF SOUTHWEST
IOWA...WEST CENTRAL IOWA...EAST CENTRAL NEBRASKA...NORTHEAST
NEBRASKA AND SOUTHEAST NEBRASKA.

.DAY ONE...THIS AFTERNOON AND TONIGHT

ISOLATED TO SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP BY
EARLY AFTERNOON FOR AREAS ALONG AND EAST OF A LINE FROM WAYNE TO
COLUMBUS. SOME OF THESE THUNDERSTORMS MAY BECOME SEVERE WITH LARGE
HAIL. THE GREATEST CONCENTRATION OF THUNDERSTORM ACTIVITY IS
EXPECTED TO BE OVER WESTERN IOWA FROM MID TO LATE AFTERNOON.

COLD TEMPERATURES ALOFT COMBINED WITH MOISTURE AND WARM
TEMPERATURES AT THE SURFACE WILL PRODUCE AN UNSTABLE AIR MASS.
THIS IS EXPECTED TO PRODUCE STORMS WITH HAIL. THUNDERSTORM
ACTIVITY SHOULD DIMINISH AROUND SUNSET DUE TO THE LOSS OF DAYTIME
HEATING.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

A POTENT UPPER LEVEL STORM SYSTEM WILL BRING THE CHANCE OF
THUNDERSTORMS BACK TO THE REGION FROM WEDNESDAY NIGHT INTO FRIDAY.
THE MOST LIKELY TIME FOR SEVERE THUNDERSTORMS IS FROM THURSDAY
NIGHT INTO FRIDAY.
