AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 328 PM CDT MON AUG 30 2010 .SHORT TERM...TONIGHT. STRONG SOUTH WINDS WILL CONTINUE OVERNIGHT...DRAWING NEAR 70 DEW POINTS NORTH THROUGH MOST OF THE CWA. HIGH HUMIDITY AND MIXING WILL KEEP LOWS NEAR OR ABOVE 70 ACROSS ALL OF OUR AREA. COLD FRONT WILL REMAIN WEST OF THE CWA TONIGHT AS IT WAITS FOR UPPER TROUGH TO BEGIN PUSHING INTO THE PLAINS. HOWEVER ZONE OF MID LEVEL WARM ADVECTION WILL OVERSPREAD THE CWA AND COULD POP SCATTERED CONVECTION OVERNIGHT...SIMILAR TO THIS MORNING. NAM AND GFS BOTH HINT AT THIS SCENARIO...WITH 4KM WRF MOST BULLISH IN DEVELOPING A LINE OF CONVECTION IN WESTERN NEBRASKA AND MAINTAINING STRENGTH THROUGH EASTERN NEBRASKA OVERNIGHT. ALREADY SEEING SOME CONVECTIVE DEVELOPMENT IN NORTH CENTRAL NEBRASKA...SO WILL KEEP HIGHEST POPS IN OUR NORTHWEST ZONES THIS EVENING. AS LOW LEVEL JET STRENGTHENS OVERNIGHT...EXPECT CONVECTION TO INTENSIFY NEAR AND NORTH OF THE SOUTH DAKOTA BORDER...BUT THOSE STORMS SHOULD MOVE AWAY FROM OUR CWA. AFTER 06Z...ISENTROPIC UPGLIDE ALONG 315K SURFACE WILL ALIGN NEARLY NORTH TO SOUTH JUST WEST OF THE MISSOURI RIVER...THEN SPREAD EAST WITH TIME. HOWEVER DRIER AIR WILL BE ADVECTING INTO THE AREA AS THE LOW LEVEL JET BECOMES MORE WESTERLY. NAM AND GFS FORECAST SOUNDING SUGGEST 500 TO 1000 J/KG OF ELEVATED CAPE WILL BE AVAILABLE...HOWEVER BOTH SHOW MODEST CINH AS WELL. EXPECT TO SEE SCATTERED SHOWERS/STORMS WELL AFTER MIDNIGHT ACROSS EASTERN HALF OF THE CWA AS TOP DOWN EVAPORATION ERODES CAP...BUT COVERAGE IS STILL IN QUESTION. WILL CONTINUE WITH OUR HIGHEST POPS ACROSS THE NORTHERN CWA NEARER AFOREMENTIONED SOUTH DAKOTA CONVECTION...WITH SLIGHT CHANCE POPS IN THE SOUTH WHERE ELEVATED DEVELOPMENT/COVERAGE IS EXPECTED TO BE LESS PROBABLE/WIDESPREAD. .LONG TERM...TUESDAY THROUGH MONDAY. A FEW LINGERING ELEVATED TSTMS ARE POSSIBLE TUESDAY MORNING...ESPECIALLY EAST OF THE MISSOURI RIVER WHERE BEST AREA OF ISENTROPIC UPGLIDE RESIDES. THIS COULD AFFECT TEMPERATURES EARLY ON SO WL BE A CHALLENGING FIRST HALF OF THE DAY.

INSTABILITY IS EXPECTED TO GREATLY INCREASE BY MID TO LATE AFTERNOON AHEAD OF THE FRONTAL BOUNDARY WITH MUCAPE VALUES FORECAST IN THE 2500-3500J/KG RANGE. 0-6KM BULK SHEAR NOT EXPECTED TO BE MUCH OVER 30-35KTS AS BULK OF UPPER FORCING REMAINS FAR TO OUR NORTH. A FEW MINOR IMPULSES PASSING THRU THE SWRLY FLOW COULD INCREASE THIS HOWEVER. SEVERE STORMS ARE POSSIBLE MAINLY LATE AFTERNOON TUESDAY INTO TUESDAY EVENING. AREAS OF HEAVY RAIN ARE POSSIBLE AS WELL ALONG THE BOUNDARY WITH PW'S SLIGHTLY ABOVE 2 INCHES. FRONTAL BOUNDARY SLIDES SOUTH INTO NRN KS BY WEDNESDAY MORNING AND QUICKLY MOVES NWD AS A WRMFNT THRU THE DAY BRINGING MOISTURE BACK WITH IT. RAIN LOOKS POSSIBLE THROUGHOUT THE DAY WEDNESDAY AND INTO NIGHT AS ISENTROPIC FORCING IS MAINTAINED THRU THE PD. PCPN IS FORECAST TO MOVE OUT BY THURSDAY MORNING AS ANOTHER COLD FRONT SWEEPS THRU BRINGING DRIER AND COOLER AIR TO THE REGION. COOL HIGH PRESSURE BUILDS IN FOR THE WEEKEND WITH RETURN FLOW SETTING UP BY EARLY SUNDAY. A FEW CHANCES OF TSTMS ARE POSSIBLE IN WARM ADVECTION REGIME HOWEVER CONFIDENCE IS FAIRLY LOW ON TIMING. && .AVIATION...
