AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
259 AM CST MON FEB 9 2009

.DISCUSSION...
SHOWERS ARE OVERSPREADING THE CWA THIS MORNING AHEAD OF BROADER
PRECIP SHIELD.  SUBJECTIVE 00Z UPPER AIR ANALYSIS INDICATES BROAD
UPPER RIDGE EXTENDING FROM GULF OF MEXICO THROUGH THE MO VALLEY AND
INTO NRN CANADA.  UPPER LOW CENTERED IN SRN UT WAS DEEPENING...WITH
500MB HT FALLS OF 120M IN AZ.  NEXT UPSTREAM UPPER WAVE WAS ALSO
COMING ASHORE IN THE PAC NW...WITH 500MB HT FALLS UP TO 170M ALONG
THE OR COAST INDICATING ITS MOVEMENT.  MAIN NRN STREAM JET ENERGY
WAS WELL N...WITH JET CORE EXTENDING FROM PAC NW COAST THROUGH CTRL
CANADA.  SRN STREAM UPPER JET EXTENDED ACROSS MEXICO INTO TX.  GULF
WAS WIDE OPEN AT 850MB...WITH STRONG LOW-LEVEL JET FROM THE TX COAST
THROUGH THE DAKOTAS.  AREA PROFILER NETWORK INDICATED 850MB WINDS OF
50-60KT ACROSS OK/KS.  850MB DEWPOINTS OF 6C+ REACHED ALL THE WAY
INTO NEB AT 12Z ON THE NOSE OF THE WARM/MOIST AIR ADVECTION.  SFC
PRESSURE GRADIENT WAS TIGHTENING...WITH SFC LOW AT 08Z CENTERED IN
NERN WY/SERN MT AND SECONDARY LOW CENTERED IN NERN CO.

MANY FORECAST CONCERNS IN THE NEXT 24 HRS...INCLUDING POTENTIAL FOR
MODERATE RAINS...THUNDERSTORMS...AND STRONG GRADIENT WINDS.  FIRST
IN A SERIES OF UPPER WAVES/LOWS IS APPROACHING THE CWA.  EXPECT RA
TO CONTINUE TO INCREASE IN COVERAGE THIS MRNG AS WAVE APPROACHES AND
MID/UPPER LEVEL RIDGE PULLS AWAY.  00Z NAM INDICATES ELEVATED
INSTABILITY REACHING THE SRN CWA BY LATE MORNING...BUT HAVE TRIMMED
THUNDER OUT OF NRN CWA UNTIL AFTER 18Z.  GRADIENT WINDS WILL
INCREASE THROUGH THE MRNG...ESPECIALLY AFTER 18Z AS LOW-LEVEL WARM
AIR ADVECTION AIDS IN MIXING.  WITH SUCH STRONG WINDS TO MIX DOWN IN
ADDITION TO STRONG GRADIENT WINDS...FEEL A WIND ADVISORY IS
JUSTIFIED IN THE SRN CWA.  OVERALL RAIN POTENTIAL IS MODEST...BUT
MAY BE ENOUGH TO GENERATE ICE ACTION ON A FEW AREA STREAMS AND
RIVERS.  WILL CONTINUE TO MONITOR RIVER STAGES...WITH CURRENT ESF
HANDLING EVENT WELL FOR NOW.

LOW-LEVEL WARM AIR ADVECTION SHOULD HELP CREATE AT LEAST MARGINAL
SURFACE-BASED INSTABILITY AROUND 300-500 J/KG THIS AFTN IN THE SRN
CWA...WITH NEGATIVE LI ACROSS THE AREA AS WELL.  FCST SOUNDINGS
INDICATE ABUNDANT SHEAR...WHICH MAY COMBINE WITH MARGINAL
INSTABILITY TO ALLOW A FEW THUNDERSTORMS TO REACH SEVERE LEVELS /IN
A LOW-TOPPED SUPERCELL TYPE ENVIRONMENT/.  WITH ALREADY STRONG
GRADIENT WINDS...EXPECT GUSTY WINDS TO BE THE PRIMARY HAZARD.
MARGINAL HAIL IS ALSO POSSIBLE...THOUGH CAPE ABOVE FREEZING LEVEL IS
MARGINAL.  WITH SUCH STRONG 0-1KM SHEAR THIS AFTN /AROUND
35-40KTS/...WILL ALSO NEED TO BE COGNIZANT OF TORNADO POTENTIAL.
TIME OF YEAR IS NOT CLIMATOLOGICALLY FAVORED...AND ABSENCE OF A SFC
BDRY/CONVERGENCE ZONE WILL ALSO BE A LIMITING FACTOR IN
POTENTIAL...BUT PATTERN IS CLOSE TO A FAIRLY TYPICAL COLD-CORE
CLOSED LOW SET-UP.  SEVERE THREAT THIS AFTN IS CONDITIONAL ON
REALIZING A LITTLE SFC-BASED INSTABILITY.

PRECIP SHIELD WILL LIFT NEWD AND OUT OF THE CWA THIS EVNG.  NEXT
SYSTEM IS QUICK ON ITS HEELS AS AN UPPER LOW DIVES OUT OF CTRL CA
INTO THE SRN PLAINS BY LATE TUES.  WITH NRN STREAM INFLUENCE ON THAT
WAVE...MODELS HAVE CONTINUED TO TREND SOUTHWARD...EITHER JUST
SKIRTING THE SERN CWA OR KEEPING IT DRY.  KEPT A SMALL AREA OF CHC
POPS IN THE SRN CWA 06-18Z WED.  WITH CURRENT PROGGED TEMPERATURE
PROFILES...PRECIP ON THE NRN FRINGE OF THAT SYSTEM WILL LIKELY START
AS RAIN GIVEN POCKET OF WARM LOW-LEVEL AIR...THEN CHANGE TO A
RAIN/SNOW MIX AS MID-LEVEL COLDER AIR SPILLS IN BEHIND THE LOW.

ACTIVE PATTERN WILL CONTINUE THROUGH THE NEXT WEEK...WITH SYSTEMS
CROSSING THE PLAINS AGAIN ON FRI AND SUN.  WITH ATTENTION TO MORE
IMMINENT SYSTEMS...MADE NO CHANGES BEYOND WED NT.

513 PM CST SUN FEB 8 2009

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

.DAY ONE...TONIGHT AND MONDAY

ISOLATED THUNDERSTORMS ARE EXPECTED OVER THE REGION MONDAY AS A
STRONG STORM SYSTEM MOVES NORTHEAST ACROSS NEBRASKA. INSTABILITY
SHOULD REMAIN FAIRLY LIMITED THROUGHOUT THE DAY DUE TO LACK OF
STRONG HEATING AND EXTENSIVE CLOUD COVER...HOWEVER A DRY SLOT
COULD WRAP INTO THE SYSTEM BY AFTERNOON...ALLOWING DESTABILIZATION
TO OCCUR...ESPECIALLY ACROSS SOUTHEAST NEBRASKA AND SOUTHWEST
IOWA. THERE IS A SMALL POSSIBILITY FOR ISOLATED LOW TOPPED
SUPERCELLS OR A BROKEN SQUALL LINE TO DEVELOP. IF THAT WERE TO
OCCUR...A FEW STORMS COULD PRODUCE ISOLATED TORNADOES. ACROSS THE
REMAINDER OF THE OUTLOOK AREA...MARGINALLY SEVERE STORMS WILL BE
POSSIBLE LATE MONDAY MORNING THROUGH MONDAY AFTERNOON. A FEW SEVERE
WIND GUSTS AND SMALL HAIL ARE POSSIBLE.

IN ADDITION...EVEN JUST MODERATE AMOUNTS OF RAIN COULD PROVIDE ENOUGH
RUNOFF TO BREAK UP ICE ON AREA RIVERS CAUSING ICE JAM FLOODING...
ESPECIALLY SINCE THE RAIN WILL BE FALLING ON A MOSTLY FROZEN
GROUND. ALTHOUGH THE THREAT IS HIGH ON ANY RIVER OR STREAM WITH
SUBSTANTIAL REMAINING ICE COVER...THE AREAS MOST SUSCEPTIBLE
INCLUDE THE PLATTE RIVER DOWNSTREAM FROM COLUMBUS...THE ELKHORN
RIVER FROM NORFOLK TO ITS CONFLUENCE WITH THE PLATTE...AND THE
LOUP RIVER DOWNSTREAM OF MONROE.

IN ADDITION TO THE POTENTIAL SEVERE WEATHER AND ICE JAM FLOODING...STRONG
SOUTH WINDS ARE EXPECTED THROUGHOUT LATE MORNING AND INTO EARLY
TUESDAY EVENING. SUSTAINED WINDS OVER 30 MPH ARE POSSIBLE WITH
GUSTS NEAR 40 MPH...ESPECIALLY ACROSS SOUTHEAST NEBRASKA AND
SOUTHWEST IOWA.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY

ANOTHER STORM SYSTEM IS FORECAST TO MOVE ACROSS THE SOUTHERN
PLAINS BY MIDWEEK. THE PATH OF THIS STORM IS SOMEWHAT UNCERTAIN
AND MODELS CONTINUE TO INDICATE IT WILL MOSTLY AFFECT LOCATIONS
SOUTH OF THE AREA. HOWEVER...IF THE TRACK MOVES FARTHER
NORTH...PARTS OF THE OUTLOOK AREA COULD SEE LIGHT ACCUMULATING
SNOW.

YET ANOTHER STORM SYSTEM MAY TRACK THRU THE REGION NEXT FRIDAY AND SATURDAY.
THIS COULD BRING A MIX OF RAIN AND SNOW TO MUCH OF THE AREA. THE
TRACK OF THIS POTENTIAL STORM IS STILL UNCERTAIN.

STAY TUNED TO NOAA WEATHER RADIO FOR THE LATEST FORECASTS CONCERNING
THESE DEVELOPING STORMS OR POSSIBLE ICE JAM FLOODING.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED TONIGHT...BUT MAY BE NEEDED
MONDAY.
