AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE
353 PM CDT TUE AUG 1 2006
.DISCUSSION...
THE FIRST CONCERN FOR THIS FORECAST IS THE TIMING OF THE COLD FRONT
AND ASSOCIATED PRECIP AND LOWERED TEMPERATURES. A SECONDARY CONCERN
IS RETURN OF MOISTURE AND EVENTUALLY HEAT AS THE RIDGE ALOFT BUILDS
BACK WEST IN LATER PERIODS OF THE FORECAST.
IN THE SHORT TERM...HEAT ADVISORY CRITERIA HAVE BEEN REACHED FROM
AROUND I-80 SOUTH...AND WILL BE MARGINAL FROM OLU EAST THE NEXT FEW
HOURS. SAW NO REAL REASON TO CHANGE THE ONGOING HEADLINE.
SATELLITE SHOWS BUILDING CU IN THE VICINITY OF THE COLD FRONT...AND
ALSO IN S CENTRAL NEB WHERE CONVECTIVE TEMPS HAVE BEEN REACHED OR
NEARLY SO. STRONG CONVECTION IS EXPECTED TO DEVELOP ALONG THE FRONT
IN THE NEXT COUPLE OF HRS. LOW LEVEL SHEAR IS DECENT...BUT UPPER
LEVELS ARE MARGINAL AT BEST. ATMOSPHERE IS RATHER WARM FOR
HAIL...BUT SOME STRONG OUTFLOW WINDS COULD RESULT EARLY IN THE EVENT.
DEEP SUBTROPICAL MOIST PLUME LIES OVER THE AREA WITH IMPRESSIVE
PRECIPITABLE WATER VALUES. HEAVY RAIN IS POSSIBLE WITH THE
THUNDERSTORMS...BUT GROUND IS SO DRY IN NORTHEAST NEBRASKA THAT
NOTHING BUT VERY LOCAL FLOODING SHOULD RESULT. OUTFLOW/FRONTAL
BOUNDARY SHOULD WORK ITS WAY SOUTH AND MAY REACH THE KS AND MO
BORDERS BY MORNING. LOCALLY HEAVY RAIN STILL POSSIBLE..BUT IS
WORKING AGAINST MORE LOW LEVEL DRY AIR ENTRAINMENT AS TSTMS MOVE
SOUTH.
MODELS HAVE SLOWED THE SOUTHWARD PROGRESS OF THE FJRONT SOMEWHAT.
TOOK A COMPROMISE BETWEEN NAM AND SLOWER GFS. MAIN RESULT IS TO
HOLD ONTO POPS IN THE SOUTH SOMEWHAT LONGER...WITH PRECIP LINGERING
PERHAPS AS LATE AS EARLY THU MORNING IN THE FAR SOUTHEAST. TEMPS
WILL MUCH COOLER TOMORROW...ESPECIALLY IN THE SOUTH WHERE CLOUDS AND
PRECIP ARE LIKELY TO PERSIST THROUGH THE DAY.
COOLER AND DRY WEATHER WILL PERSIST INTO THE WEEKEND. THEN...RETURN
FLOW BRINGS WARMER TEMPS AND ESPECIALLY ANOTHER SURGE OF SUBTROPICAL
PLUME. THIS REGIME SHOULD THEN PERSIST UNTIL THE UPPER RIDGE MOVES
FAR ENOUGH WEST TO BUILD WARM AIR ALOFT AND ADVECT DEEPER MOISTURE
TO OUR EAST. THIS WILL LIKELY BE MONDAY OR TUESDAY. UNTIL
THEN...INTRODUCED OR INCREASED POPS ACROSS THE AREA. BEST POPS IN
NORTH WHICH WILL CATCH THE WESTERLIES BETTER AND RECEIVE PRECIP FROM
ANY RIDGE RUNNER WAVES.

LATEST 00Z SUBJECTIVE SURFACE ANALYSIS INDICATES WEAK LOW PRESSURE JUST EAST OF COLUMBUS. SURFACE TROUGH EXTENDED SOUTH INTO NORTHERN KANSAS...AND A WARM FRONT EXTENDED NORTHEAST FROM THE LOW ACROSS NORTHEAST NEBRASKA. CONVECTION...SOME SEVERE CONTINUES ACROSS PARTS OF EASTERN NEBRASKA. SLIGHTLY ELEVATED SUPERCELLS TRACKED ACROSS PIERCE AND CEDAR COUNTIES PRODUCING SOME WIND AND HAIL AS EXPECTED. ATTENTION IS NOW TURNING FARTHER SOUTH TO NEAR INTERSECTION OF THE SURFACE LOW AND TROUGH. ATMOSPHERE REMAINS DEEPLY MIXED ALONG THE SURFACE TROUGH PER LATEST OBJECTIVE ANALYSIS...AND THUNDERSTORMS DEVELOPING IN THIS ATMOSPHERE WILL HAVE A BETTER WIND THREAT THROUGH THE NEXT 2 HOURS. LIMITED DEEP LAYER SHEAR IS ALLOWING FOR ELEVATED CORES IN THIS ACTIVITY TO DESCEND TO THE SURFACE AND WITH AROUND 1300 J/KG OF DCAPE PER LATEST RUC...AND PRODUCE DAMAGING WINDS AS PER RECENT BUTLER COUNTY STORM. AS THE BOUNDARY LAYER COOLS BY 03Z...SURFACE PARCELS SHOULD GENERALLY BE CAPPED AS NOCTURNAL INVERSION DEVELOPS GENERALLY ENDING THE WARM SECTOR DAMAGING WIND THREAT. OTHERWISE...WE ARE EXPECTING CONVECTION TO INCREASE IN AN AREA FROM ALBION TO COLUMBUS AND NORTHEAST ALONG THE BOUNDARY AGAIN AS THE LOW LEVEL JET DEVELOPS THROUGH THE EVENING. MID LEVEL LAPSE RATES CONTINUE TO LIMIT SEVERE WEATHER POTENTIAL...BUT SUFFICIENT LOW LEVEL SHEAR WILL ALLOW FOR SOME UPDRAFT ORGANIZATION AND ROTATION FOR STORMS ALONG THE BOUNDARY FOR ISOLATED SEVERE THROUGH 06Z. OTHER THREAT IN THIS AREA WILL BE HEAVY RAIN WITH NEARLY 2 INCHES OF PWATS AND A FAVORABLE WIND PROFILE FOR SOME BACK-BUILDING. BOUSTEAD
