AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 300 PM CDT WED MAY 11 2005 .DISCUSSION... FORECAST CONCERNS CONTINUE TO BE SEVERE WX POTENTIAL AND HEAVY RAINFALL THROUGH THURSDAY. TEMPERATURES THROUGHOUT THE PERIOD ALSO CHALLENGING. LATEST SUBJECTIVE SFC ANALYSIS CONTINUES TO BE QUITE COMPLICATED WITH MAIN WARM FRONT EXTENDING ACROSS FAR NRN KS WITH OUTFLOW BOUNDARY EXTENDING INTO NWRN MO. ANOTHER BOUNDARY IS SITTING ACROSS FAR SRN NEB AND STORMS ARE FIRING ALONG THIS BOUNDARY ACROSS SOUTH CENTRAL NEB NOW. STORMS CONTINUE TO FIRE ACROSS WARM FRONT IN NERN KS AND ALONG OUTFLOW ACROSS NWRN MO. THIS ONGOING CONVECTION HAS KEPT MID 60S SFC DEWPOINTS FROM REACHING OUR FORECAST AREA THIS AFTERNOON...THUS LIMITING OUR INSTABILITY AND KEEPING STRONG CONVECTION TO OUR SOUTH. AS WAS EXPECTED...WE HAVE SEEN A LULL IN ACTIVITY ACROSS MUCH OF THE CWA EARLY THIS AFTERNOON AS A WEAK DRY SLOT HAS WORKED INTO THE AREA AS WAS SUGGESTED BY THE 12Z NAM. A FEW JUNKY STORMS CONTINUE TO PUSH EAST ACROSS SWRN IA...BUT MUCH OF THE FORECAST AREA REMAINS DRY EARLY THIS AFTERNOON. SFC LOW PRES CENTER OVER ERN CO WL SLIDE INTO ERN KS OVERNIGHT WITH INVERTED TROF MOVING THROUGH CNTRL NEB JUST AS LLJ INCREASES. EXPECT AN INCREASE IN WIDESPREAD SHOWER AND THUNDERSTORM ACTIVITY LATE THIS AFTERNOON AND INTO THE OVERNIGHT AS THIS SYSTEM SLOWLY MOVES EAST. WITH STRONG THETA-E ADVECTION TONIGHT...WL HANG ON TO FLOOD WATCH FOR ONLY SWRN IA COUNTIES AND ALSO A FEW IN EXTREME NERN NEB. THE WATCH AREA COVERS THOSE COUNTIES THAT HAD SIGNIFICANT RAINS LAST NIGHT AND THUS ONE HOUR FLASH FLOOD GUIDANCE IS NEAR OR LESS THAN 1 INCH. STILL FEEL THAT HEAVY RAIN IS POSSIBLE ACROSS MUCH OF FORECAST AREA...HOWEVER THOSE AREAS THAT DID NOT RECEIVE RAINFALL LAST NIGHT SHOULD BE ABLE TO HANDLE AN INCH OR SO OVERNIGHT WITHOUT MUCH FLOODING CONCERN. SHOULD SEE QUITE A GRADIENT IN TEMPS TOMORROW...SIMILAR TO TODAYS...AS THE SFC BOUNDARY WORKS ITS WAY SEWD. PCPN SHOULD FOCUS ALONG THIS INTO LATE THURSDAY NIGHT AND WL END PCPN FROM NW TO SE BY EARLY FRIDAY. SFC HIGH PRESSURE MOVES DOWN FOR THE WEEKEND AND WL SEE DRY CONDITIONS WITH TEMPS MAINLY IN THE 60S. OVERNIGHT LOWS SHOULD DIP INTO THE LOWER 40S WITH LIGHT WINDS AND CLEAR SKIES TO HELP RADIATE OUT. SFC HIGH PUSHES EAST LATE SUNDAY SETTING US UP FOR RETURN FLOW AND A SLIGHT WARM UP FOR THE EARLY PART OF THE WEEK. NEXT FRONT MOVES THROUGH THE AREA LATE MONDAY INTO TUESDAY AND WL GO WITH NEXT CHANCE OF THUNDERSTORMS ALONG THIS BOUNDARY THROUGH TUESDAY. OTHERWISE...ZONAL FLOW SETS UP BY MID WEEK AND WL GO WITH A DRY FORECAST FOR DAY 7. && .OAX WATCHES/WARNINGS/ADVISORIES...
