AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 320 AM CDT SUN JUL 11 2004 .DISCUSSION... MAIN FORECAST CHALLENGES INCLUDE TIMING OF PRECIPITATION THIS MORNING...THEN TEMPERATURE TRENDS THROUGH MID WEEK...AND NEXT CHANCE OF PRECIP MAINLY WEDNESDAY AND SATURDAY. CLUSTER OF HEALTHY THUNDERSTORMS MOVING THROUGH THE CWA AT THIS TIME SEEM TO BE FEEDING OFF THE LOW LEVEL JET ALONG AN INSTABILITY AXIS IN AN AREA OF ENHANCED MOISTURE CONVERGENCE. ONE STORM PRODUCED QUARTER SIZED HAIL ABOUT 1/2 HOUR AGO...AND OTHER STORMS HAVE PRODUCED PEA SIZED HAIL AND WIND GUSTS OF 30 TO 50 MPH. DESPITE FORECAST SLOW MOVING STORMS...IN REALITY THE STORMS ARE MOVING ABOUT 25 TO 30 MPH...THUS EVEN THOUGH BRIEF HEAVY RAIN HAS OCCURRED...IT APPEARS THAT THE FLOOD POTENTIAL HAS DIMINISHED...AND WILL CANCEL THE ONGOING FLOOD WATCH EARLY. AT THEIR PRESENT RATE...THE FIRST CLUSTER SHOULD BE OUT OF THE FORECAST AREA BEFORE 600 AM...HOWEVER WILL CONTINUE A CHANCE OF ADDITIONAL THUNDERSTORMS MAINLY EASTERN TWO THIRDS THIS MORNING AS SHORT WAVE AXIS PIVOTS THROUGH. PRECIPITATION CHANCES WILL BE ENDING FROM WEST TO EAST...WITH SKIES BECOMING MOSTLY SUNNY THIS AFTERNOON. TEMPERATURES TODAY SHOULD REBOUND WITH MID LEVEL TEMPERATURES BUILDING INTO THE REGION. HOWEVER...AT THE SAME TIME TEMPERATURES ACROSS EASTERN LOCATIONS WILL ALSO BE TEMPERED BY DEBRIS CLOUDINESS FROM OUR WEST. THUS...HAVE READJUSTED THE ORIENTATION OF THE GRADIENT SOMEWHAT IN THE NEW GRIDS...WITH MID TO UPPER 80S ACROSS SOUTHWEST IOWA AND LOWER 90S ACROSS THE WESTERN CWA BORDER. OTHERWISE...DIDNT HAVE A LOT OF TIME TO LOOK AT THE REMAINDER OF THE FORECAST...WHICH APPEARS TO BE ON TRACK. WITH RIDGING BUILDING ALOFT...AM EXPECTING A HOT DAY ON MONDAY WITH TEMPERATURES WELL INTO THE 90S. AM KEEPING AN EYE ON THE NEXT SYSTEM...WHICH APPEARS TO BE A RIDGE RUNNER MOVING THROUGH THE DAKOTAS THROUGH THE DAY MONDAY...AND THEN TAKES A TURN SOUTHEAST INTO THE UPPER MISSISSIPPI RIVER VALLEY MONDAY NIGHT. AN ASSOCIATED SURFACE TROUGH UNDERCUTS THE RIDGE AND MOVES INTO THE FORECAST AREA MONDAY NIGHT ALSO...BUT STILL FEEL THAT VERY WARM MID LEVEL TEMPERATURES SHOULD KEEP THE ATMOSPHERE CAPPED. THE GREATEST POTENTIAL FOR THE CAP TO BE BROKEN APPEARS TO BE ALONG THE MISSOURI RIVER ACROSS NORTHEAST NEBRASKA... BUT WILL MAINTAIN A DRY FORECAST AT THIS TIME. THE AFOREMENTIONED FRONTAL TROUGH SEEMS TO SET UP JUST WEST AND SOUTH OF THE REGION ON TUESDAY AND IS HELD AT BAY BY A RIDGE OF HIGH PRESSURE NOSING IN FROM THE NORTH. THAT SHOULD ALLOW TEMPERATURES TO EASE BACK WITH A NORTHEASTERLY FLOW THROUGH THE REMAINDER OF THE WEEK. THE SLIGHT CHANCE OF RAIN ON WEDNESDAY NOW LOOKS SUSPECT WITH BEST CHANCE ALONG THE FRONTAL BOUNDARY FARTHER WEST AND SOUTH...BUT FOR NOW HAVE NOT TINKERED WITH THE GRIDS THIS EARLY...AND WILL DEFER TO THE DAY SHIFT FOR ANY ADJUSTMENTS. OTHERWISE...THERE STILL APPEARS TO BE A SMALL CHANCE OF RAIN EARLY NEXT WEEKEND WITH A WEAK WAVE MOVING THROUGH THE NORTHERN PLAINS IN NORTHWEST FLOW...THAT MAY BE FAR ENOUGH SOUTH TO AFFECT US. && .OAX WATCHES/WARNINGS/ADVISORIES...
