AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
425 PM CDT SAT SEP 16 2006
.DISCUSSION...
THE MAIN CONCERN FOR THIS FORECAST IS SEVERE WEATHER IN THE SHORT
TERM. BEST DESTABILIZATION APPEARS TO BE AHEAD OF THE DRYLINE.
VERY STRONG SHEAR OVER THE WHOLE AREA WILL SUPPORT SUPERCELLS...BUT
A MORE LINEAR DEVELOPMENT MAY OCCUR LATER IN THE EVE AFTER BEST CAPE
IS USED UP AND STORMS BECOME MORE OUTFLOW DOMINATED.
LEFT WIND ADVISORY UNTIL 7 PM. WINDS REMAIN STRONG AND OCCASIONALLY
HIT CRITERIA...AND THIS SHOULD LAST FOR A WHILE.
HEAVY RAINS LAST NIGHT RESULTED IN ONGOING FLOODING IN SAUNDERS CO.
WHILE SOME STORMS COULD HAVE HEAVY RAIN TONIGHT...EXPECT STORMS TO
BE FAST MOVING WITH STRONG WINDS ALOFT. BEST MOISTURE IS IN SE
CORNER NEBRASKA AND SW IA...WHICH HAD LESS RAIN RECENTLY AND SO NOT
VERY PRONE TO FLOODING. TRAINING POTENTIAL IS NOT AS GREAT AS LAST
NIGHT EITHER.
DRYING ALOFT SHOULD PUT AN END TO THUNDERSTORMS BEFORE ACTUAL COLD
FRONT ARRIVES LATER TONIGHT. COOLER AND BLUSTERY CONDITIONS SHOULD
THEN PREVAIL THROUGH MONDAY. GFS AND NAM SUGGEST THAT WRAPAROUND
SHOWERS MAY CUT ACROSS THE NORTH SUNDAY NIGHT AND MONDAY.
BEYOND MONDAY...THERE WERE FEW SIGNIFICANT CHANGES TO THE PREVIOUS
FORECAST. MODELS ARE QUICK TO DEVELOP MAJOR DISPARITIES ON TIMING
AND PLACEMENT OF MAJOR FEATURES...STARTING WITH THE UPPER LOW TO OUR
NORTH. THIS CERTAINLY MAKES A LOW CONFIDENCE FORECAST. NATIONAL
DISCUSSIONS FAVOR 00Z ECMWF...AND ACTUAL FORECAST WAS A BLEND OF
THIS AND PREVIOUS FORECAST. THE MAJOR DIFFERENCE WAS TO TREAT THE
POSSIBLITY OF AN UPPER TROUGH OVER THE WESTERN U.S. WITH MOIST
SOUTHWEST FLOW INTO OUR AREA LATER NEXT WEEK. THIS IS COMPLETELY AT
ODDS WITH SEVERAL OP GFS RUNS...BUT ENSEMBLES ARE ALL OVER THE MAP.
THUS...INCREASED TO CHANCE POPS FOR THURSDAY AND KEPT GOING THROUGH
FRIDAY NIGHT...WITH SLIGHT CHC FOR SATURDAY. WOULD EXPECT THAT
FORECAST NEEDS SERIOUS MODIFICATIONS FOR THIS PERIOD AS IT BECOMES
APPARENT WHICH MODEL...IF ANY...IS BELIEVABLE.

AT 19Z THE SURFACE LOW WAS LOCATED OVER NORTH CENTRAL NEBRASKA WITH THE DRYLINE SOUTH INTO WESTERN KANSAS...WITH THE DRYLINE STARTING TO SHOW SIGNS OF BULGING TO THE NORTHEAST AROUND HILL CITY KS INTO SOUTH CENTRAL NEBRASKA. MODIFYING THE 18Z KOAX OBSERVED SOUNDING YIELDS ONLY AROUND 70 G/KG OF MIXED LAYER INHIBITION ALONG A LINE FROM NEAR ONEILL SOUTH TO HEBRON. 1940Z VISIBLE SATELLITE IMAGERY INDICATED BOUNDARY-LAYER CUMULUS CONTINUES TO DEVELOP WITHIN THIS REGION OF WEAKER INHIBITION. CURRENT THINKING CONTINUES TO BE THAT STORMS WILL DEVELOP FIRST OVER NORTH CENTRAL NEBRASKA AHEAD OF THE SURFACE LOW AS IT MOVES INTO SOUTHEAST SOUTH DAKOTA. SOME OF THESE THUNDERSTORMS MAY AFFECT THE KNOX AND CEDAR COUNTY AREA THROUGH 430 PM. OTHERWISE...AS CONVERGENCE INCREASES NEAR THE DRYLINE BULGE OVER CENTRAL NEBRASKA...AND TEMPERATURES INCREASE INTO THE LOWER 90S...SHOULD SEE AN ISOLATED THUNDERSTORM DEVELOP IN THESE REGION BY 5 PM. OBJECTIVE ANALYSIS FROM THE RUC CONTINUES TO POINT TO THE POTENTIAL FOR SUPERCELLS WITH ANY STORM THAT DEVELOPS...ALONG WITH THE THREATS OF LARGE HAIL...DAMAGING WINDS AND ISOLATED TORNADOES.

AT 21Z SURFACE LOW WAS NOW NEAR LAKE ANDES SOUTH DAKOTA AND MOVING TO THE NORTHEAST. THE DRYLINE EXTENDED SOUTH THROUGH ALBION TO GRAND ISLAND TO JUST WEST OF HEBRON. THE COLD FRONT WAS ADVANCING EAST...CATCHING UP TO THE COLD FRONT OVER NORTH CENTRAL NEBRASKA. WE ARE STILL EXPECTED TWO AREAS OF CONVECTION DEVELOP THIS EVENING. THE FIRST IS STILL EXPECTED OVER NORTHEAST NEBRASKA IN KNOX OR ANTELOPE COUNTIES. LATEST VISIBLE SATELLITE IMAGERY INDICATES BOUNDARY LAYER CUMULUS CONTINUE TO SHOW SIGNS OF TOWERING IN THIS REGION. MAY LIMITING FACTOR HERE IS DRY MID LEVEL AIR RAPIDLY MOVING INTO THE REGION AND A LACK OF SURFACE CONVERGENCE. NEVERTHELESS...WOULD EXPECTED AN ISOLATED STORM TO DEVELOP IN THIS AREA AS 70 KT 500 MB JET OVER WEST CENTRAL NEBRASKA AT 21Z WORKS EASTWARD. OTHER AREA OF CONCERN IS ALONG THE DRYLINE FROM NEAR COLUMBUS TO HEBRON WHERE VISIBLE SATELLITE IMAGERY IS ALSO SHOWING CUMULUS STARTING TO TOWER. CONVERGENCE IS INCREASING IN THIS AREA WITH WINDS OVER NORTHEAST KANSAS BACKED TO THE SOUTH INCREASING CONVERGENCE. LATEST OBJECTIVE ANALYSIS INDICATED ATMOSPHERE IS WEAKLY CAPPED. IN BOTH AREAS DEEP LAYER SHEAR REMAINS QUITE FAVORABLE FOR ORGANIZED THUNDERSTORMS...INCLUDING SUPERCELLS. ALTHOUGH TORNADO THREAT IS NOT IMMEDIATELY HIGH...ONCE THUNDERSTORMS DEVELOP AND SURFACE TEMPERATURES BEGIN TO COOL BACK INTO THE MID 80S...TORNADO THREAT MAY INCREASE BETWEEN THE 7 AND 9 PM TIME FRAME.

MID LEVEL SUBSIDENCE IN ASSOCIATED WITH THE UPPER LEVEL JET OVER THE REGION...ALONG WITH LACK OF CONVERGENCE HAS ELIMINATED THE CHANCES NORTHWEST OF A LINE FROM COLUMBUS TO WAYNE NEBRASKA. FARTHER SOUTH...KOAX 88-D NOW STARTING TO INDICATE THAT CONVECTIVE INITIATION HAS TAKEN PLACE NEAR THE CITY OF HEBRON. THIS INITIATION IS ALONG THE DRYLINE WHICH EXTENDS FROM NEAR YORK SOUTH INTO CENTRAL KANSAS. THUNDERSTORMS ARE EXPECTED TO CONTINUE TO EXPAND IN COVERAGE AND INTENSITY AS IT MOVES INTO OUR FAR SOUTHWEST COUNTIES OF JEFFERSON AND SALINE. CONVECTIVE INITIATION ALSO SEEMS TO BE TRYING TO TAKE PLACE ALONG THE COLD FRONT OVER SOUTH CENTRAL NEBRASKA. PRIMARY SEVERE WEATHER THREAT WOULD BE WITH ANY STORM THAT DEVELOPS ALONG THE DRYLINE OVER SOUTHEAST NEBRASKA AS SHEAR VECTORS CONTINUE TO INDICATE THAT STORMS WOULD BE ABLE TO MOVE OFF THE BOUNDARY INTO A VERY FAVORABLE SHEAR FOR SUPERCELLS. MAIN THREAT WILL BE LARGE HAIL AND DAMAGING WINDS...BUT AS MENTIONED EARLIER...BY MID EVENING LOW LEVEL AIRMASS SHOULD COOL AND MAY ALLOW FOR SOME LOWER LIFTED CONDENSATION LEVELS AND AN ISOLATED TORNADO POTENTIAL. OTHER STORMS SHOULD CONTINUE TO ORGANIZE ALONG THE COLD FRONT WITH A POSSIBLE SQUALL LINE DEVELOP THERE. BOUSTEAD
