AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 335 PM CDT SUN MAY 26 2002 FORECAST CHALLENGES--THUNDERSTORMS AND POSSIBLE SEVERE WEATHER AND HIGH TEMPERATURES THE NEXT SEVERAL DAYS. SYNOPSIS--MORNING RAOB ANALYSIS SHOWS RETURN OF 850 MB MOISTURE OCCURRING OVER THE PLAINS...WITH THE 8 DEGREE OR HIGHER ISODROSOTHERMS AS FAR N AS LBF. MAIN TRANSPORT OF LOW LEVEL MOISTURE IS TAKING PLACE INTO CENTRAL NEBRASKA. MORNING RAOB AT OAX INDICATED STEEP LAPSE RATES ABOVE 850 MB. HOWEVER...LOW LEVEL MOISTURE WAS NOT VERY DEEP. MOISTURE IS MAINLY OUT TO THE WEST. FORECAST--COMPLEX OF THUNDERSTORMS WILL BEGIN TO AFFECT THE NWRN PART OF THE OAX CWA EARLY THIS EVENING. AT THIS TIME...BELIEVE SEVERE THREAT WILL BE ISOLATED AS CURRENT RADAR IMAGERY INDICATES MULTICELL STORMS. ALTHOUGH NELIGH PROFILER IS SHOWING SOME O-2 KM AND O-3KM HELICITY VALUES AROUND 120...BELIEVE FOR THE TIME BEING STORMS WILL CONTINUE MULTICELLULAR. MODELS DO INDICATE THAT THE LOW LEVEL JET AXIS WILL SLOWLY MOVE EASTWARD INTO CENTRAL AND EASTERN NEBRASKA. ETA MODEL CONTINUES TO INDICATE CORFIDI VECTORS THAT ARE SOUTHEAST IN EASTERN NEBRASKA. IF STORMS MOVE SOUTHEAST...THEN I WOULD EXPECT HODOGRAPH HELICITY VALUES TO INCREASE AND ISOLATED SUPERCELLS MAY DEVELOP AND PRODUCE LARGE HAIL. THUNDERSTORM COMPLEX MAY LINGER INTO MORNING...ESPECIALLY OVER THE SOUTHEAST. BELIEVE NORTHEAST NEBRASKA WILL AGAIN BE THE WARMEST TOMMOROW ..WHILE CLOUDS MAY KEEP TEMPERATURES LOWER FURTHER SOUTH. ANOTHER COMPLEX MAY AFFECT THE AREA MONDAY NIGHT. BUT AT THIS TIME...IT APPEARS THAT THE NORTHERN PART OF THE OAX CWA WILL BE AFFECTED BY THAT. IN THE EXTENDED...THUNDERSTORM CHANCES ARE POSSIBLE EACH DAY EXCEPT THURSDAY AND FRIDAY. THUNDERSTORMS ARE THEN POSSIBLE SATURDAY AND SUNDAY. SMITH 235 AM CDT SUN MAY 26 2002 FORECAST CHALLENGES -- PRECIPITATION CHANCES THE NEXT FEW DAYS AND SEVERE WEATHER POTENTIAL TONIGHT AND MONDAY. SYNOPSIS -- EARLY MORNING MOISTURE CHANNEL IMAGERY SHOWED A WEAK SHORTWAVE CURRENTLY MOVING ACROSS THE AREA INTO SRN IA/NRN MO. INSPECTION OF 26/00Z SOUNDINGS AND PLAN VIEW U/A DATA SHOWED DEEPER LOW-LEVEL MOISTURE AS FAR N AS OUN AND AMA. 850 MB WINDS ON THE PROFILER NETWORK INDICATE THAT A MODEST LOW-LEVEL JET HAS DEVELOPED THIS MORNING OVER THE HIGH PLAINS, WHICH IS EFFECTIVELY TRANSPORTING THIS MOISTURE NWD INTO THE AREA. AT THE SURFACE, A WEAK FRONTAL BOUNDARY EXTENDED FROM NWRN MN TO A WEAK LOW OVER CNTRL SD, THEN INTO ERN WY AT 06Z. A SECOND BOUNDARY, WHICH DENOTES A NWD SURGE IN HIGHER DEWPOINTS EXTENDED FROM CNTRL NEB INTO S-CNTRL MN WITH UPPER 40S TO LOWER 50S DEWPOINTS OBSERVED TO THE S OF THIS FEATURE. FORECAST -- INTERESTING AND COMPLEX FORECAST SHAPING UP FOR THE NEXT COUPLE OF DAYS, WITH MANY DETAILS ON THE MESOSCALE. IN THE SHORT TERM, WE WILL CONTINUE TO MONITOR RADAR AND SATELLITE DATA IN THE VICINITY OF THE DEWPOINT DISCONTINUITY AS ALL 3 SHORT RANGE MODELS WANT TO GENERATE PRECIPITATION OVER FAR NERN NEB BY 12Z. BOTH QG FORCING AND ISENTROPIC ASCENT ARE MINIMAL ALONG THIS FEATURE, WITH ONLY SOME SLOW-LEVEL MASS CONVERGENCE FORECAST. BY THIS AFTERNOON, THE ETA HAS SHOWN RUN-TO-RUN CONSISTENCY IN DEVELOPING A WEAK LOW OVER N-CNTRL NEB, AT THE TRIPLE POINT OF A DIFFUSE E-W BOUNDARY NEAR THE NEB/SD BORDER AND A TROUGH/DRYLINE THAT EXTENDS SWD INTO WRN KS. IF THIS VERIFIES, THE POTENTIAL FOR INITIATION OF DEEP CONVECTION WILL BE OFF TO OUR W AND N, WITH CORFIDI VECTORS INDICATING A SEWD PROPAGATION IF AN ORGANIZED CONVECTIVE SYSTEM WERE TO DEVELOP. WE WILL CONTINUE TO MENTION SLIGHT CHANCE POPS ACROSS THE N AND WILL LEAVE THE S DRY. CURRENT TEMPERATURE FORECAST IS IN GOOD SHAPE WITH HIGHS IN THE UPPER 70S TO LOWER 80S. TONIGHT, MODEL QPF VARIES WIDELY. THE ETA CHARGES AN MCS SEWD THROUGH THE AREA OVERNIGHT, WHILE THE AVN MOVES AN MCS EWD ACROSS ERN SD AND SRN MN. THE ETA MCS TRACK IS ABOUT 150 MILES W OF 2 RUNS AGO, WITH THE AVN SHOWING A WIDE VARIANCE AS WELL. THUS, WE WILL JUST CARRY 30 PERCENT POPS AREAWIDE AND LET THE DAYSHIFT SORT OUR THE DETAILS (WHICH MAY NOT YET BE EVIDENT 12 HOURS FROM NOW). SEVERE WEATHER POTENTIAL ON MONDAY AFTERNOON/EVENING WILL BE CONTINGENT ON THE EVENTUAL TRACK OF SUNDAY NIGHTS MCS. IT DOES APPEAR THAT OUR NRN ZONES STAND THE BEST CHANCE OF SEEING A SEVERE WEATHER EVENT. ALTHOUGH MODERATE TO STRONG AMOUNTS OF INSTABILITY WILL BE WIDESPREAD ACROSS THE AREA, DETAILS POINT TO NERN NEB. 1) A FRONTAL BOUNDARY WILL BE IN THE AREA, LOCALLY BACKING SURFACE WINDS TO AN ELY DIRECTION. THIS WILL ENHANCE HODOGRAPH LENGTH, AS THIS AREA WILL RESIDE UNDER THE STRONGEST MID-LEVEL FLOW (I.E. WLY WINDS OF 35-40 KTS AT 500 MB) 2) FORECAST SOUNDINGS FOR YKN, OFK AND SUX SHOW LOWER LCL AND LFC HEIGHTS, WITH 0-3 KM CAPE VALUES IN EXCESS OF 100 J/KG ALONG THE SD/NEB BORDER BY LATE AFTERNOON. FARTHER S, WE WILL PROBABLY HAVE TO WAIT FOR CONVECTION MOVING NEWD OUT OF KS AHEAD OF THE CLOSED, MID-LEVEL CIRCULATION THAT WILL BE MOVING INTO THE PLAINS. WE HAVE ADJUSTED TEMPERATURES UPWARD ON MONDAY, ESPECIALLY ACROSS OUR WRN ZONES, BUT NOT AS WARM AS THE FWC VALUES, THERE CONTINUES TO BE MODEL DISAGREEMENT ON THE MOVEMENT OF THIS CLOSED, MID-LEVEL SYSTEM. THE AVN HAS SLOWED THE MOVEMENT OF THIS TROUGH, BUT NOW SEEMS TO BE BRINGING IT OUT IN PIECES, WHEREAS THE ETA MAINTAINS ONE FEATURE. CURRENT THINKING IS THAT THE BEST CHANCES FOR PRECIPITATION ON TUESDAY WILL OCCUR ACROSS OUR SRN ZONES, IN THE VICINITY OF A WEAK SURFACE LOW AND FRONTAL SYSTEM. WE WILL DROP THE MENTION OF PRECIPITATION TUESDAY NIGHT ACROSS OUR NRN ZONES, AND LEAVE SMALL POPS IN THE S. ON WEDNESDAY, THE AVN IS ADVERTISING THE ARRIVAL OF A NWLY FLOW SHORTWAVE AND ASSOCIATED COLD FRONT. IT APPEARS THAT THERE WILL BE RESIDUAL MOISTURE TO WORK WITH AHEAD OF THIS FRONT, SO WE WILL LEAVE THE LOW END POPS. A DEVELOPING MID-LEVEL RIDGE OVER THE SRN ROCKIES WILL BEGIN TO BUILD NEWD THROUGH THE REMAINDER OF THE FORECAST. IT APPEARS THAT ANY LOW-LEVEL MOISTURE WILL REMAIN CONFINED TO THE GULF COAST AT THIS TIME, AND NO CHANGES ARE PLANNED FOR THE THURSDAY-SATURDAY FORECAST.

A SEVERE THUNDERSTORM WATCH HAS BEEN ISSUED UNTIL 11 PM FOR AREAS WEST OF A LINCOLN TO BEATRICE LINE. AN AREA OF THUNDERSTORMS CONTINUES TO DEVELOP OVER CENTRAL NEBRASKA. THIS ACTIVITY HAS BEEN MOVING EASTWARD ABOUT 20 MPH. THE AIR MASS AHEAD OF THESE STORMS IS UNSTABLE AND VERTICAL WIND SHEAR PROFILES AARE BECOMING MORE FAVORABLE FOR SEVER THUNDERSTORMS. THE PRIMARY THREAT WITH THESE STORMS IS LARGE HAIL AND DAMAGING WINDS. SPOTTERS...ESPECIALLY THOSE IN PARTS OF SOUTHEAST NEBRASKA...SHOULD BE PREPARED TO BE ACTIVATED AS THESE STORMS MOVE CLOSER TO THE AREA THIS EVENING. ANOTHER ROUND OF THUNDERSTORMS WILL BE POSSIBLE ON MONDAY AFTERNOON AND EVENING. ALTHOUGH THE EXACT LOCATION OF ANY FRONTS OR OUTFLOW BOUNDARIES WILL BE DEPENDANT ON THE THUNDERSTORMS TONIGHT...IT APPEARS THAT THE HIGHEST PROBABILITY OF SEVERE WEATHER WILL BE ACROSS NORTHEAST NEBRASKA INTO WESTERN IOWA.
