AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 250 PM CDT FRI JUL 2 2004 .DISCUSSION... STACKED LOW PRESSURE OVER EASTERN KANSAS WILL CONTINUE TO MOVE SLOWLY EAST TONIGHT INTO SATURDAY. THIS WILL BRING PERIODS OF SHOWERS AND ISOLATED THUNDERSTORMS TO MUCH OF THE CWA THIS EVENING. THE RAIN MAY GO THROUGH A DIURNAL CYCLE WHERE IT DIMINISHES A BIT AFTER SUNSET...HOWEVER THINK THERE WILL BE ENOUGH UPPER LEVEL FORCING AND VERTICAL MOTION TO KEEP A CHANCE OF SHOWERS GOING ALL NIGHT. WILL LINGER A CHANCE OF RAIN INTO SATURDAY IN THE EAST AS THE LOW DEPARTS...BUT STILL MANAGES TO EXERT SOME INFLUENCE OVER MAINLY THE IOWA PORTIONS OF THE CWA. A FRONT IS THEN FORECAST TO DROP INTO NORTHEAST NEBRASKA SATURDAY AFTERNOON AND WILL CONTINUE TO CARRY A LATE AFTERNOON CHANCE OF THUNDERSTORMS ALONG THIS BOUNDARY. THINGS GET A BIT MORE COMPLICATED SATURDAY NIGHT AS THE ETA AND GFS DIVERGE A BIT. THE ETA POINTS TO MCS DEVELOPMENT OVER CENTRAL NEBRASKA AND MOVES THIS SOUTHEAST...WHILE THE GFS IS FOCUSED A BIT FURTHER NORTH AND WEST. FOR NOW WILL CARRY A SMALL CHANCE OF THUNDERSTORMS TO COVER...THOUGH CONFIDENCE IN EITHER SOLUTION IS LOW. WARM AIR ADVECTION AND ISENTROPIC LIFT WILL BRING A CHANCE OF THUNDERSTORMS SUNDAY NIGHT AHEAD OF AN APPROACHING COLD FRONT. WILL CONTINUE THE THUNDERSTORM CHANCES MONDAY INTO EARLY TUESDAY AS THE COLD FRONT PASSES THROUGH THE CWA. WILL DRY IT OUT FOR THE REST OF THE EXTENDED WITH LITTLE FOCUS FOR PRECIPITATION ACROSS THE AREA. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...NONE. IA...NONE. && KING
