AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 907 PM CDT THU JUL 26 2007 .UPDATE... UPDATED GRIDS FOR LATEST CONVECTIVE TRENDS. && .DISCUSSION... THUNDERSTORMS FINALLY POPPED OVER NORTHEAST NEBRASKA BUT DID NOT LAST LONG. IN FACT...THE STORMS WENT AWAY COMPLETELY FOR A COUPLE OF HOURS THIS EVENING...AND WERE JUST BEGINNING TO PUSH BACK INTO THE CWA FROM THE WEST. A QUICK LOOK AT EVENING UPPER AIR CHARTS SHOWED PLENTY OF MOISTURE STILL IN PLACE ACROSS THE CWA AND POINTS NORTH...WITH 850 DEW POINTS IN THE 11-15C RANGE...AND 700 DEW POINTS GREATER THAN 6C. SURFACE COLD FRONT SLIPPED SOUTH THROUGH NORTHEAST NEBRASKA DURING THE EVENING...AND WAS APPROACHING A COLUMBUS TO TEKAMAH LINE. IT WILL LIKELY CONTINUE ITS SLOW DRIFT SOUTH THROUGH THE NIGHT AS PER LATEST RUC FORECASTS. AS FAR AS PRECIPITATION CHANCES GO...SATELLITE LOOPS WERE NOT INDICATING MUCH IN THE WAY OF UPPER IMPULSES TO TRIGGER ADDITIONAL DEVELOPMENT...AND A RATHER ANEMIC LOW LEVEL JET WILL BE HARD PRESSED TO FIRE STORMS. HOWEVER WITH PLUME OF MONSOONAL MOISTURE OVER NORTHERN NEBRASKA AND SINKING SOUTH...CAN NOT RULE OUT SCATTERED SHOWERS OR STORMS OVERNIGHT. THUS WILL MAINTAIN CHANCE CATEGORY POPS OVERNIGHT...BUT RISK OF SEVERE STORMS HAS PASSED. && .PREV DISCUSSION... /ISSUED 314 PM CDT THU JUL 26 2007/ DISCUSSION... FORECAST CONCERNS CENTER AROUND TSTMS OVERNIGHT AND FRIDAY. LATEST WATER VAPOR IMAGERY OVERLAID WITH RUC 500MB ANALYSIS SHOWS A RATHER NOISY PICTURE WITH FIRST SHORTWAVE OF CONCERN RIDING OVER TOP OF THE RIDGE ACROSS NRN SD WITH THE NEXT ONE IN LINE ACROSS WYOMING. 12Z 700MB UPPER AIR ANALYSIS SHOWED QUITE A BIT OF MOISTURE TO OUR NORTH WITH SUBTROPICAL MOIST PLUME EXTENDING FM SWRN CONUS WELL THRU THE NRN PLAINS. LATEST SFC ANALYSIS HAS CDFNT EXTENDING FM CNTRL MN THRU CNTRL NEB AND INTO SERN CO. SFC DEWPOINTS HAVE BEEN POOLING INTO THE LOWER 70S ALONG AND AHEAD OF THE BOUNDARY LEADING TO A MODERATELY UNSTABLE ATMOSPHERE ACROSS ERN NEB/WRN IA WITH TEMPS IN THE 90S. CU FIELD CONTINUES TO INCREASE ALONG THE BOUNDARY ACROSS ERN SD AND CNTRL NEB AND EXPECT THIS TREND TO CONTINUE AND BE THE FOCUS FOR TSTM DEVELOPMENT AS THE BOUNDARY PUSHES S OVERNIGHT AND PREVIOUS MENTIONED SHORTWAVE TOPPING THE RIDGE MOVES SEWD ACROSS ERN NEB. SOME SEVERE STORMS STILL POSSIBLE INITIALLY ACROSS NERN NEB ONCE INHIBITION IS OVERCOME. WIND STILL EXPECTED TO BE THE MAIN THREAT IN ADDITION TO LOCALLY HEAVY RAIN. 850MB DEWPOINTS REMAIN QUITE HIGH EVEN BEHIND THE FRONT AND WITH SUBTROPICAL MOIST PLUME MOVING INTO THE CNTRL PLAINS OVERNIGHT...PWS ARE IN THE 1.75 TO 2.00 RANGE ALONG THE THETA-E AXIS. TSTMS EXPECTED TO INCREASE IN COVERAGE AS THE FRONT PUSHES S THRU THE FORECAST AREA TONIGHT AND UPPER LEVEL SUPPORT SLIDES INTO THE AREA. MODEL QPF CONTINUES TO INDICATE PCPN BAND WELL BEHIND THE FRONT AS WELL AS FORCING FM SHORTWAVE ENERGY WHICH SHOULD SUSTAIN PCPN INTO FRIDAY MORNING HOURS. HAVE GONE MORE TOWARDS A GFS SOLUTION WHERE PCPN LAGS BEHIND FRONT RATHER THAN THE NAM WHICH IS QUICK TO DISSIPATE PCPN. THE LATTER SOLUTION IS HARD TO BELIEVE WITH SHORTWAVE ENERGY BEHIND THE INTIAL WAVE MOVING THRU CNTRL NEB. THIS FEATURE COULD GIVE SERN NEB A DESCENT SHOT OF MORE TSTMS THRU FRIDAY AFTERNOON WHICH IS CLOSER TO MOIST AXIS THAT HANGS UP ACROSS NRN KS. HIGH TEMPS ON FRIDAY SHOULD BE MUCH COOLER IN THE MID 80S WITH LOWER 80S POSSIBLE UNDER THICKER CLOUD COVER WITH DEWPOINTS IN THE 60S. GFS PAINTS ANOTHER SHORTWAVE MOVING ACROSS CNTRL NEB SATURDAY NIGHT INTO SUNDAY WHICH COULD BE YET ANOTHER CHANCE FOR OUR SWRN COUNTIES TO GET SOME TSTMS AS MOIST AXIS REMAINS OVER THE AREA. RIDGE BUILDS YET AGAIN OVER THE CNTRL PLAINS BY MONDAY AFTERNOON WITH TEMPERATURES RISING INTO THE 90S AND DEWPOINTS SURGING UP AGAIN INTO MID WEEK NEXT WEEK. ANOTHER COLD FRONT SHOULD DIVE SOUTH SOMETIME LATE WED/EARLY THUR GIVING THE AREA OUR NEXT SHOT OF PCPN. AVIATION... CDFNT NERN NEB SHOULD TO ADVANCE TO OFK ARND 23Z AND REACH OMA AND LNK AREAS ARND 06Z. SCT TSTMS EXPECTED ALONG AND N OF FNT. INITIAL STORMS IN LATE AFTN COULD HAVE STG OUTFLOW WINDS AFFECTING OFK AREA...BUT TSTMS SHOULD WEAKEN AFTER DARK AND NOT BE AS STG BY THE TIME THEY REACH LNK AND OMA. AREA OF SC WELL BEHIND FNT IN CNTRL SD LIKELY WILL HOLD TOGETHER TO REACH OFK AFTER 06Z...AND MAY REACH OMA AND LNK BEFORE 12Z. MVFR CIGS AND VSBY ARE EXPECTED...BUT THIS WILL VARY IN VCNTY TSTMS. SHWRS AND TSTMS MAY BE SLOW TO END BEHIND FNT IN SERN NEB FRI MORNING AS MID LVL MOISTURE SHOULD PERSIST. THIS WOULD TEND TO ADD MORE MOISTURE TO LWR LEVELS AND COULD DELAY DISSIPATION OF SC DECK. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...NONE. IA...NONE. && DERGAN

A SLOW MOVING COLD FRONT WILL DRIFT SOUTH THROUGH NORTHEAST NEBRASKA DURING THE EVENING WITH THUNDERSTORMS LIKELY FORMING ALONG THE FRONT. THE STORMS SHOULD LOSE SOME OF THEIR INTENSITY AFTER SUNSET. AS THE FRONT MOVES THROUGH THE REST OF EASTERN NEBRASKA AND SOUTHWEST IOWA LATER TONIGHT AND FRIDAY...MORE THUNDERSTORMS ARE POSSIBLE...BUT THOSE ARE NOT EXPECTED TO BE SEVERE. .DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY THERE IS AT LEAST A SLIGHT CHANCE FOR THUNDERSTORMS LINGERING IN SOUTHEAST NEBRASKA FRIDAY NIGHT AND SATURDAY MORNING...HOWEVER THESE SHOULD NOT BE SEVERE. ANOTHER SHOT AT THUNDERSTORMS WILL COME THURSDAY AS ANOTHER COLD FRONT APPROACHES THE AREA. .SPOTTER INFORMATION STATEMENT... STORM SPOTTER ACTIVATION MAY BE NEEDED THROUGH MIDNIGHT IN NORTHEAST NEBRASKA. DERGAN
