AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 334 AM CDT THU JUL 27 2006 .DISCUSSION... SHORT TERM...TODAY AND TONIGHT. THUNDERSTORMS CHANCES...ALBEIT GENERALLY SMALL...ARE THE MAIN FORECAST CHALLENGE. WATER VAPOR STLT IMAGERY SHOWED MAIN SHORT WAVE TROUGH TO AFFECT FORECAST AREA WAS PUSHING TOWARD CNTRL SD/NWRN NEBR BY 08Z. EXTRAPOLATION ON CURRENT MOVEMENT WOULD PUT IT INTO VCNTY OF ECNTRL NEBR BY EARLY AFTERNOON. QUESTION IS HOW MUCH PCPN WILL IT GENERATE AS IT MOVES ACROSS THE CWA. THRU 18Z LOW LVL JET IS MEAGER AT BEST BUT SOME 850 MB THETA E ADVCTN WAS NOTED THROUGH 12Z ON NAM ALONG WITH LOW LVL MOISTURE CONVERGENCE NERN/ERN NEBR THRU 18Z. ISOLD CONVECTION THAT DEVELOPED EARLIER ON OUTFLOW BOUNDARY FM OLU-OFK HAD DISPTD BUT A FEW SHOWERS REMAINED JUST SW OF THE CWA AS OF 08Z. WHILE QPF FM GFS IS GENERALLY ABSENT OVER THE FCST AREA TODAY...00Z NAM GENERATED SAME MUCH OF THE DAY WHILE UKMET AND 4.5KM WRF COMPOSITE REFLECTIVITY DVLPD QPF/RETURNS OVR ERN NEBR IN 12Z-18Z PD. LATTER DVLPD INCREASING RETURNS BEGINNING AROUND 10Z SPREADING IT E/SE WHILE WEAKENING IT INTO EARLY AFTN BEFORE GENERATING BULK OF PCPN WITH SHORTWV ENERGY MOSTLY SE THROUGH E OF THE CWA. BASED FORECAST ON BLEND OF GFS AND WRF 4.5KM AND THUS INSERTED SMALL POPS MOST ZONES THIS MORNING SHIFTING CHCS THIS AFTN TO ERN ZONES. NAM AND WRF 4.5KM DO DVLP LATE AFTN CONVECTION ON SFC TROF AXIS/DRYLINE CNTRL NEBR...BUT FEEL IF THIS DOES INDEED OCCUR IT WOULD NOT MOVE INTO NWRN ZONES TILL EVENING. SO INCLUDED NWRN ALONG WITH ERN ZONES AND INSERTED SOME EVENING POPS AS WELL. BETTER FORCING AND LOW LVL THETA E ADVCTN SHIFTS ENE OF FORECAST AREA BY THEN SO PCPN MAY HAVE ALREADY SHIFTED OUT OF THE CWA. WITH PLENTY OF MID LVL MOISTURE AVAILABLE...CLOUDS INTO EARLY AFTN COULD HOLD TEMPS DOWN A BIT SERN ZONES...BUT CLEARING SHOULD OCCUR ACROSS THE NW. THUS WENT CLOSER TO MAV TEMPS NWRN ZONES WHERE AFTERNOON SUN LOOKS ABUNDANT AND WITH A BLEND OF MAV/NAM ELSEWHERE. AFTER THIS EVENING RAIN CHCS GREATLY DIMINISH UNTIL PROBABLY THE TUE- WED PD WITH FORECAST FOCUS TURNING TO HEAT AS UPPER RIDGE BUILDS ACROSS PLAINS. TEMPERATURES SHOULD MAKE A RUN AT 100 EACH DAY MOST AREAS FROM FRIDAY THROUGH SUNDAY AT LEAST. ANY WEAK WAVE RIDING OVER RIDGE AT THE RIGHT TIME PROVIDING A BIT MORE OF A SW WIND AND BETTER DOWNSLOPE/MIXING IN THE AFTN COULD POSSIBLY PUSH READINGS SVRL DEGREES ABOVE 100. FOR NOW MADE LTL CHANGES TO TEMPS WITH SIMILAR HIGHS/LOWS THROUGH MONDAY ALTHOUGH IT WAS NOTED THAT BOTH THE GFS AND CMC BROUGHT A SUB TROPICAL TYPE UPPER LOW TOWARD NEBR IN THE LATE SUN/MON PD. THIS WILL HAVE TO BE MONITORED BECAUSE ASSOCD MOISTURE WITH IT COULD TRIGGER ISOLD CONVECTION AND TEMPS A CATEGORY OR TWO LOWER THAN FORECAST...SPCLY MONDAY. RIDGE EVENTUALLY SHIFTS E BY MID WEEK WITH SOME TIMING DIFFERENCES BTWN 00Z GFS AND ECMWF WITH THE LATTER SLOWER. ALTHOUGH GFS MAY BE TOO FAST IN BRINGING FRONT THROUGH FCST AREA BY 00Z WED...DID INTRODUCE SLGT POPS NWRN ZONES TUE AFTN NWRN ZONES TO ACCOUNT FOR A ECMWF/GFS BLEND. && .OAX WATCHES/WARNINGS/ADVISORIES...
