Area forecast discussion, Jul 3, 1:35 PM CST, 8 hours before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 235 PM CDT SAT JUL 3 2004 .DISCUSSION... MAIN FORECAST PROBLEMS SURROUND RAIN CHANCES THROUGH MONDAY NIGHT. A FEW SHOWERS DEVELOPED IN WESTERN IOWA THIS AFTERNOON ON THE BACK SIDE OF THE DEPARTING UPPER LEVEL TROF. EXPECT THE TROF TO BE FAR ENOUGH EAST BY ZONE TIME THAT ANY RAIN ASSOCIATED WITH IT WILL REMAIN EAST OF THE CWA. NEXT ISSUE BECOMES THE POSSIBLE MCS TONIGHT WITH THE ETA AND GFS NOW HAVING COME INTO AGREEMENT. AN INCREASING LOW LEVEL JET...STRONG MOISTURE CONVERGENCE BETWEEN 925 AND 850 MB ALONG WITH THE NOSE OF THE 850 MB MOISTURE TRANSPORT VECTORS SUGGEST MCS DEVELOPMENT IN WESTERN/CENTRAL NEBRASKA TONIGHT. EXPECT THIS TO THEN MIGRATE EAST/SOUTHEAST AS PER THE CORFIDI VECTORS AND MEAN 850-300MB WIND WHICH WILL MAINLY IMPACT SOUTHEAST NEBRASKA. WILL GO AHEAD AND INCREASE RAIN CHANCES OVER SOUTHEAST NEBRASKA INTO THE LIKELY CATEGORY AFTER MIDNIGHT AND MENTION HEAVY RAIN...AND THEN TAPER POPS TO CHANCE CATEGORY FARTHER NORTH. WILL CARRY A SMALL CHANCE POP INTO SUNDAY MORNING OVER SOUTHEAST NEBRASKA DUE TO THE DEPARTING MCS...AND THEN GO MAINLY DRY UNTIL SUNDAY NIGHT. APPEARS BEST RAIN CHANCES SUNDAY NIGHT WILL BE WEST AND SOUTH OF CWA WHERE THE LOW LEVEL JETS CRANK UP. THE LOW LEVEL BOUNDARIES WILL ALSO BE IN THOSE SPOTS WITH A TROF ACROSS WESTERN NEBRASKA AND A WARM FRONT INTO CENTRAL KANSAS. WILL CARRY A SMALL CHANCE OF THUNDERSTORMS SUNDAY NIGHT IN CASE THE STORMS WHICH DEVELOP WEST CAN MAKE IT INTO THE AREA LATER SUNDAY NIGHT AND BECAUSE THE GFS PLACES THE WARM FRONT FARTHER NORTH. THE CHANCE OF SHOWERS AND THUNDERSTORMS INCREASES AGAIN ON MONDAY AS A COLD FRONT MOVES ACROSS THE CWA. THIS WILL ALSO HAVE SOME UPPER LEVEL SUPPORT AS A SHORTWAVE MOVES THROUGH THE CENTRAL PLAINS. WILL GO WITH HIGH CHANCE CATEGORY POPS FOR NOW AND MAY NEED TO INCREASE THEM TO LIKELY LATER ON. WILL FOLLOW THE ETA AND CONTINUE THE DRY FORECAST STARTING ON TUESDAY...THOUGH THE GFS DOES TEND TO LINGER RAIN INTO EARLY TUESDAY MORNING IN THE EASTERN CWA. THOUGHT ABOUT ADDING A CHANCE OF THUNDERSTORMS TO THURSDAY NIGHT DUE TO WARM AIR ADVECTION...HOWEVER DECIDED TO GO DRY FOR NOW AND FOCUS POPS FRIDAY INTO SATURDAY AS ANOTHER COLD FRONT MOVES ACROSS THE AREA. && .OAX WATCHES/WARNINGS/ADVISORIES...
