AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 329 AM CDT THU AUG 16 2007 .DISCUSSION... MAIN FORECAST CHALLENGE IS TSTM CHANCES TODAY AND RESIDUAL CLOUDS AFFECTING TEMPS. TWO MCS COMPLEXES HEADING EAST INTO THE FORECAST AREA THIS MORNING. NORTHERN MOST CURRENTLY AFFECTING NORTH CENTRAL NEB AND BEGINNING TO MOVE INTO NERN NEB. THINK A FEW REMNANTS WILL REMAIN ACROSS THE NORTH BY 15Z...BUT LLVL CONVERGENCE LACKING TO SUPPORT ACTIVITY MUCH FURTHER SOUTH. BEST CHANCE FOR TSTMS WL BE WITH THE SOUTHERN COMPLEX MOVING ACROSS NWRN KS/SWRN NEB. SFC BOUNDARY GENERALLY EXTENDING ACROSS THE NEB/KS BORDER AND 35-40KT LLVL JET NOSING INTO THE AREA SHOULD FEED SCATTERED ACTIVITY THRU MUCH OF THE MORNING ACROSS SRN ZONES. SFC DEWPOINTS REMAIN IN THE LOW 70S WELL NORTH OF THE BOUNDARY WHICH IS CAUSING SOME REDUCTION IN VISIBILITIES WITH SFC TEMPS IN THE 70S BUT NOT EXPECTING MUCH IN THE WAY OF DENSE FOG THIS AM. DRIER DEWPOINTS (60S) SHOULD BEGIN TO ADVECT INTO THE NRN COUNTIES LATER THIS MORNING/EARLY AFTERNOON AS HI PRES MOVES ACROSS THE ERN DAKOTAS AND MN. THIS HI PRES SYSTEM PUSHES SFC BOUNDARY INTO NRN KS/MO BY LATE IN THE DAY AND SO SHOULD BE PCPN FREE THROUGH THE EVENING HOURS WITH VERY PLEASANT TEMPS/DEWPOINTS. FOLLOWED MORE CLOSELY TO MET/FWC TEMP GUIDANCE WITH MID 80S NORTH OF THE BOUNDARY AND AROUND 90 ALONG THE KS/NEB BORDER. MAV HAS BEEN RUNNING MUCH TO WARM LATELY. FRIDAY SHOULD BE DRY AND STRONG RETURN FLOW SETS UP BY FRIDAY NIGHT. HAVE REDUCED POPS FRIDAY NIGHT/SATURDAY MORNING AS IT LOOKS LIKE MAIN COMPLEX WL BE WELL TO OUR NORTHEAST WHERE LLVL CONVERGENCE AND THETA-E ADVECTION ARE STRONGEST. MAY SEE SOME LIGHT ACTIVITY SKIRT THE FAR NERN COUNTIES SO WL KEEP SMALL POP IN TO COVER THIS. HAVE REDUCED POPS ON SAT AND SUN AS WELL AS SFC BOUNDARY FORECAST TO REMAIN DRAPED NORTH OF THE AREA. STILL ANY LITTLE PERTURBATION IN THE WESTERLIES COULD SPARK SOMETHING SO CANT RULE OUT A CHANCE OF TSTMS THRU THE WEEKEND...BUT FEEL BRUNT OF ANY ACTIVITY WL BE TO OUR NORTH. OTHERWISE...NO CHANGES MADE TO GOING FORECAST WITH ACTIVE PATTERN CONTINUING INTO NEXT WEEK. && .AVIATION... HIGH PRESSURE WILL BUILD SEWD ACROSS THE NRN PLAINS TODAY...WHICH SHOULD FORCE HOTTEST AIR AND MAIN FRONTAL BOUNDARY FARTHER SOUTH. SHOWERS AND THUNDERSTORMS EARLY THIS MORNING OVER NORTH CENTRAL NEBRASKA COULD AFFECT KOFK...AND IF THEY HOLD TOGETHER AS THE TURN SOUTHEAST THEY COULD GET INTO KOMA AND KLNK LATER. ISOLATED STORMS NOW OVER SOUTHEASTERN NEBRASKA COULD AFFECT KLNK BEFORE 12Z. SOME FOG WILL OCCUR...MAINLY PATCHY...BUT COULD SEE VALUES DOWN TO ABOUT 3 MILES OR SO. FAIRLY THICK MID AND HIGH LEVEL CLOUDINESS SHOULD HELP KEEP VISIBILITY UP A LITTLE. OTHERWISE...AFTER 15Z CONDITIONS SHOULD BE VFR...OUTSIDE OF ANY THUNDERSTORM ACTIVITY. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...NONE. IA...NONE. && GRIFFIS/MILLER
