AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
308 AM CDT SAT MAR 29 2008

.DISCUSSION...

OVERALL AN UNSETTLED PERIOD FOR TONIGHT THROUGH EARLY SUNDAY...AND
ESPECIALLY FOR SUNDAY NIGHT THROUGH MONDAY.

THERE IS ONE VERY SUBTLE WAVE PUSHING THROUGH THE WESTERN HIGH PLAINS
EARLY THIS MORNING WHICH WILL ROTATE THROUGH THE NORTHERN PLAINS
AND UPPER MISSISSIPPI RIVER VALLEY THIS AFTERNOON. DUE TO SUCH DRY
LOW LEVELS...FEEL THAT PRECIP POTENTIAL IS NIL TODAY...EXCEPT SOME
SPOTTY SPRINKLES POSSIBLY ACROSS NORTHEAST NEBRASKA THIS MORNING.
BUT MUCH BETTER CHANCES DEVELOPING OVERNIGHT. BREEZY TO WINDY
CONDITIONS EXPECTED TODAY IN RESPONSE TO A TROUGH OF LOW PRESSURE
DEVELOPING ALONG THE FRONT RANGE RESULTING IN MIXING TO ABOUT 850
MB. THIS SHOULD YIELD HIGHS INTO THE 50S...OR ABOUT A DEGREE OR
TWO JUST SHY OF MOS GUIDANCE VALUES. FEEL THAT EXTREME NORTHEAST
NEBRASKA COULD ALSO FLIRT WITH WIND ADVISORY CRITERIA OF SUSTAINED
30 MPH WINDS...THUS WILL ISSUE AN NPW FOR AREAS NORTH OF A LINE
FROM KBVN TO KOFK TO KLCG FOR LATE MORNING THROUGH LATE AFTERNOON.

OVERNIGHT AS THE FRONT DRAWS NEAR THEN MOVES INTO THE CWFA AFTER
MIDNIGHT...SCATTERED SHOWERS COULD DEVELOP THROUGH THE NIGHT. JUST
SOME SPOTTY COVERAGE IN THE EVENING AS MOISTURE DEEPENS WITH INCREASING
WAA...BUT BLOSSOMING OVERNIGHT. HAVE MY DOUBTS WELL SEE MUCH THUNDER
OVERNIGHT GIVEN BEST INSTABILITY REMAINS SOUTH ACROSS KS/MO. WILL
STILL MAINTAIN LIKELY POPS OVERNIGHT CENTRAL CWFA WITHIN REGION OF
BEST BAROCLINIC ZONE NEAR FRONTAL VICINITY. PRECIP POTENTIAL WILL
MOSTLY BE ALONG/SOUTHEAST OF I80 SUNDAY TAPERING TO LITTLE CHANCE
ACROSS NORTHEAST NEBRASKA. FAIRLY DECENT BUST POTENTIAL ON TEMPS
FOR SUNDAY BASED ON WHERE THE RAIN SETS UP AND WHERE THE
BAROCLINIC ZONE ALOFT SETS UP.

THE MOST INTERESTING PERIOD WILL BE SUNDAY NIGHT AND MONDAY AS THE
NEXT WAVE PUSHES INTO THE REGION. STRONG CYCLOGENESIS NOTED ON THE
MODELS WITH ELEVATED INSTABILITY NOTED MUCH FURTHER NORTH WELL
INTO OUR REGION. THERE ARE SOME TIMING DISCREPANCIES NOTED ON THE
MODELS...AND GENERALLY PREFERRED THE SLOWER NAM SOLUTION. BEST
CHANCE FOR PRECIP WILL COME AFTER MIDNIGHT SUNDAY AND CONTINUE
THROUGH MIDDAY MONDAY. MOSTLY RAIN...WITH SCATTERED TO NUMEROUS
THUNDERSTORMS DEVELOPING ALONG/SOUTH OF I80 AND POSSIBLY MIXED
WITH SNOW ALONG THE SOUTH DAKOTA BORDER. SWODY2 PLACES SLGHT RISK OF
SEVERE STORMS UP TO KFNB AND THIS ACTUALLY SEEMS REASONABLE GIVEN
MODEL DYNAMICS AND AMOUNT OF MOISTURE MOVING NORTHWARD. SEVERE
THREAT WILL LINGER MONDAY JUST SOUTHEAST OF THE CWFA...WHILE WE
DEAL WITH COLDER AIR FILTERING IN ON THE BACKSIDE OF THE SFC LOW.
THIS SHOULD LEAD TO A RAIN/SNOW MIXTURE ACROSS NORTHEAST NEBRASKA
MONDAY...AND RAIN OR SCATTERED THUNDERSTORMS ACROSS SOUTHWEST IOWA
AND SOUTHEAST NEBRASKA...BUT DIMINISHING THROUGH THE DAY. ALSO COULD SEE
SOME SCATTERED SNOW SHOWERS MONDAY NIGHT ALONG/NORTHEAST OF A LINE
FROM KBVN TO KOMA TO KSDA AS WE REMAIN ON THE BACKSIDE OF THE
SURFACE LOW. . AREAS ACROSS NORTHEAST NEBRASKA COULD SEE SOME
MINOR SNOW ACCUMS AS THIS WEATHER EVEN WINDS DOWN.

DID REMOVE THE CHANCE FOR THUNDER ON WEDNESDAY AS IT APPEARS THAT
QUALITY MOISTURE WILL NOT BE ABLE TO MOVE THIS FAR NORTH THAT
FAST. ACTUALLY...NORTHERN AREAS COULD STILL SEE A RAIN/SNOW
MIXTURE LATE TUESDAY NIGHT/EARLY WEDNESDAY AS THE WAVE MOVES THROUGH.

.AVIATION...
FOR TAF SITES KOMA...KLNK AND KOFK THRU 03/30 06Z.

SE SFC WINDS INCREASING TO 15-25 KTS AFT 29/16Z...OTHERWISE VFR
CONDITIONS THROUGH 30/00Z...BECOMING MVFR 30/00Z-30/06Z AS LOW
LEVEL MOISTURE SPREADS NORTH INTO THE AREA IN ADVANCE OF COLD
FRONT.
