AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 300 PM CDT WED JUL 7 2010 .DISCUSSION... ENDING RAIN CHANCES BY THURSDAY MORNING...THEN OUR NEXT ROUND OF POTENTIAL STORMS OVER THE WEEKEND...ARE THE PRIMARY FORECAST CONCERNS. COLD FRONT HAD DRIFTED INTO THE CENTRAL CWA THIS AFTERNOON EXTENDING FROM MONONA COUNTY THROUGH THE OMAHA AREA TO NEAR BEATRICE AS OF 2 PM. SCATTERED SHOWERS CONTINUED TO POP UP ALONG THE BOUNDARY...WITH A FEW LIGHTNING STRIKES NOTED FROM TIME TO TIME. MODEST INSTABILITY WAS NOTED ON SPC MESOANALYSIS AT NEARLY 2000 J/KG OF MUCAPE...BUT SHEAR WAS VIRTUALLY NONEXISTENT. SO WILL LIKELY SEE CONTINUED PERCOLATION OF STORMS THIS AFTERNOON...BUT SUSTAINED CONVECTION IS NOT EXPECTED AS STORMS RAIN THEMSELVES OUT DUE TO SLOW MOVEMENT AND VERTICAL UPDRAFTS. HOWEVER HEAVY RAIN IS A CONCERN WHERE ANY STORM DEVELOPS AS PRECIPITABLE WATER VALUES NEAR 1.5 INCHES WAS ABOUT 135 PERCENT OF NORMAL. MOST OF THE PRECIPITATION SHOULD WIND DOWN AFTER SUNSET WITH LOSS OF INSTABILITY. FRONTAL BOUNDARY WILL ALSO CONTINUE ITS SLOW DRIFT TO THE EAST AND SOUTHEAST...EXPECTED TO BE OUT OF THE CWA SHORTLY AFTER MIDNIGHT. STILL COULD SEE ISOLATED SHOWERS IN OVERRUNNING REGIME BEHIND BOUNDARY AS LATE AS THURSDAY MORNING IN OUR SOUTHEAST. LOWS TONIGHT SHOULD FALL INTO THE 50S IN OUR NORTHWEST WHERE MID 50S DEW POINTS ARE POISED JUST TO THE NORTH AND CLOUDS THIN LATER TONIGHT. EXPECT A GRADUAL CLEARING TREND DURING THE DAY THURSDAY WITH HIGH PRESSURE SETTLING INTO THE REGION. DEW POINTS SHOULD ALSO DROP THROUGH THE 60S IN MOST SPOTS. HAVE GONE A LITTLE COOLER THAN NAM/GFS MOS GUIDANCE FOR HIGHS THURSDAY THINKING LINGERING CLOUDS AND LIGHT NORTH WINDS WILL NOT PROMOTE MAXIMUM WARMING. HIGHS IN THE LOWER 80S STILL LOOK LIKELY. WILL CONTINUE DRY FORECAST THROUGH SATURDAY WITH SURFACE HIGH PRESSURE IN CONTROL OF THE WEATHER. RETURN FLOW SETS UP SATURDAY NIGHT AS UPPER FLOW BECOMES NORTHWESTERLY ACROSS MUCH OF THE MIDDLE OF THE COUNTRY...INDUCING CYCLOGENESIS IN THE NORTHERN PLAINS. THETA-E ADVECTION OVER THE CWA COULD SPARK THUNDERSTORMS SATURDAY NIGHT AND MUCH OF THE DAY SUNDAY. WILL REMAIN IN AN UNSETTLED PATTERN AT LEAST THROUGH MONDAY AS UPPER TROUGH BEGINS TO SHARPEN IN THE PLAINS AND GREAT LAKES. WILL HAVE A CHANCE FOR SHOWERS AND THUNDERSTORMS THROUGH MONDAY NIGHT WITH LAST OF SEVERAL IMPULSES DROPPING THROUGH THE TROUGH. HEIGHTS START TO BUILD ACROSS OUR AREA TUESDAY...SO DECREASING CHANCES FOR RAIN AND INCREASING TEMPERATURES ARE IN STORE BY MID WEEK. HAVE INCREASED TEMPS TOWARD 90 BY WEDNESDAY. DERGAN && .AVIATION... TAF SITES KOFK/KOMA/KLNK 18Z TAFS VFR CONDITIONS OVERALL EXPECTED DURING THE FCST PD AS A FRONTAL BNDRY CONTINUES TO DRIFT FARTHER SOUTH. EXCEPTION COMING BTWN 08/09Z-13Z...ADEQUATE LLVL MOIST COUPLED WITH LIGHT WINDS SHOULD ALLOW ONSET OF MVFR CIGS/VSBY ALL TERMINALS...AND MAY EVEN SEE OCCASIONAL IFR CIGS AT KOMA/KLNK.
