NWS Omaha, NE wrote its last area forecast discussion before the first event at Jul 7, 2:16 AM CST, 10 hours 59 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 316 AM CDT WED JUL 7 2010 .DISCUSSION... COLD FRONT IS APPROACHING THE CWA THIS MORNING...BUT PRECIP IS CERTAINLY DRAGGING ITS FEET. SUBJECTIVE 00Z UPPER AIR ANALYSIS INDICATES DOUBLE-BARRELED UPPER LOW CENTERED IN NRN CANADA AND IN NRN MB...WITH TROUGH EXTENDING THROUGH MT/ID/NRN CA. WEAK SHORTWAVE WAS ALSO EVIDENT IN IA/NRN MO EXTENDING SWWD THROUGH OK. ANOMALOUS UPPER HIGH WAS CENTERED AROUND WV. POCKETS OF DEEPER MOISTURE WERE IN PLACE ON THE WRN SIDE OF THE UPPER HIGH ACROSS THE WRN GREAT LAKES TO THE MID-MS RIVER VALLEY...AND FROM TX NWD THROUGH THE CNTRL PLAINS. ABRUPT 850MB TEMPERATURE DROP WAS NOTED BEHIND THE COLD FRONT EXTENDING FROM MB THROUGH CENTRAL SD AND INTO CO...WITH 9C AT KRAP AND 22C AT KLBF. STEEPER LAPSE RATES WERE MOVING OUT OF THE SWRN STATES INTO THE HIGH PLAINS...WITH 700-500MB TEMP DIFFERENCE OF 20C+ EXTENDING INTO WRN NEB/WRN KS...WHICH HAS ALLOWED MORE WIDESPREAD TSRA COVERAGE THROUGH THE EVENING/OVERNIGHT HOURS. CONVECTIVELY ENHANCED COLD FRONT AT 07Z EXTENDED FROM NEAR KFSD TO KBVN TO KHLC...THOUGH TRUE SYNOPTIC FRONT LIKELY LAGS THE WIND SHIFT SOMEWHAT. IN WAKE OF THE FRONT...TEMPS IN WRN NEB/WRN SD HAVE DROPPED AT LEAST INTO THE 50S. MAIN PRECIP SHIELD AT 07Z WAS WEST OF THE CWA...THOUGH ISOLATED TSRA WERE DEVELOPING NEAR THE CWA ALONG/JUST BEHIND THE OUTFLOW AHEAD OF THE MAIN PRECIP. MAIN FORECAST CONCERN IS EVOLUTION OF RAIN/THUNDER THROUGH THURSDAY ASSOCIATED WITH COLD FRONTAL PASSAGE. SHRA/TSRA THIS MORNING HAS EVOLVED INTO TWO MAIN SEGMENTS...A FASTER-MOVING NORTHERN COMPLEX MOVING FROM ERN SD INTO MN AND A SLOWER-MOVING SOUTHERN COMPLEX TRUDGING ACROSS WRN/CNTRL NEB. ISOLATED TSRA HAVE ALSO POPPED UP NEAR KYKN AND ACROSS CNTRL NEB/CNTRL KS. EXPECT ACTIVITY TO CONTINUE TO GROW UPSCALE TONIGHT AND CONTINUE TO MOVE EWD...WITH FASTER MOTION INTO NERN NEB AND SLOWER PROGRESS INTO SRN CWA. CONVECTION IS MOVING NORTH-NORTHEASTWARD AHEAD OF SLOW-MOVING FRONT...CONTRIBUTING TO THE SLOW EASTWARD PROGRESS. HAVE PLAYED DOWN POPS IN THE SERN CWA THIS MRNG...THINKING THAT AREA MIGHT ACTUALLY REMAIN DRY FOR SEVERAL HOURS INTO THE DAY. DO EXPECT RAIN WILL EVENTUALLY WORK INTO THE ENTIRE CWA THROUGH THE DAY...BUT CONFIDENCE REMAINS LOW ON WHEN AND HOW LONG ANY GIVEN LOCATION WILL EXPERIENCE RAINFALL. AS A RESULT...POPS ARE LOWER THAN USUALLY WOULD ASSIGN FOR A FIRST PERIOD EVENT WITH RAIN ALREADY ON THE SCOPE...EVEN WITH FAIR CONFIDENCE THAT ENTIRE CWA WILL RECEIVE MEASURABLE RAIN DURING THE EVENT. DID ADD HEAVY RAIN WORDING TO THE ISO TSRA MENTION THIS AFTERNOON...WHEN CONFIDENCE FOR PRECIP TO BE IN THE CWA IS HIGHER...AS ANY EMBEDDED TSRA WILL BE ABLE TO PRODUCE LOCALLY HEAVY RAINFALLS. AMONG UNCERTAINTIES WITH THIS EVENT IS THE AMOUNT OF RAIN AT ANY GIVEN LOCATION...BUT COULD SEE A HALF INCH TO AN INCH WITH HIGHER AMOUNTS ANYWHERE THAT TSRA CAN TRAIN. COOLER/DRIER AIRMASS BEHIND THE FRONT SHOULD BEGIN TO PUSH IN LATER THIS EVENING AND THROUGH TONIGHT. HAVE COOLED MINS AND CLEARED PRECIP MORE QUICKLY TONIGHT...WITH A SCHC LINGERING INTO THURS IN THE SRNMOST CWA AS PRECIP LINGERS ALONG THE SLOW-MOVING FRONT. MODELS INDICATE COLD PUSH WILL DAMPEN WEDNESDAY NIGHT/THURSDAY AS 850MB FRONT WASHES OUT ACROSS THE CNTRL PLAINS...BUT FRONTAL PASSAGE WILL STILL DROP TEMPS/DEWPOINTS A FEW DEGREES. KEPT TEMPS IN THE LOWER 80S THURS/FRI AS A SURFACE HIGH MOVES THROUGH THE MO RIVER VALLEY...WITH WEAK MIXING AND SOMEWHAT COOLER 850MB TEMPS. RETURN FLOW WILL PICK UP ON SATURDAY AS SFC HIGH SLIDES AWAY TO THE EAST...WITH TEMPS INCREASING TO CLOSER TO NORMALS. PRECIP SHOULD REMAIN SOUTH/WEST THROUGH THE DAY. MADE NO CHANGES BEYOND SATURDAY. && .AVIATION... TAF SITES KOFK/KOMA/KLNK 06Z TAFS A CDFNT FM NW KS INTO SERN SD WL PUSH INTO SERN NEBRASKA BY LATE THIS AFTN. IN ADDITION...SOME MID AND HIGH LVL MOISTURE HAS SPREAD BACK INTO THE REGION AHEAD OF THE FRONT. CLOUDS ASSOCD WITH THIS MOISTURE SHOULD LIMIT FOG DEVELOPMENT THIS MORNING AND ALTHOUGH LOWER VSBYS ARE POSSIBLE...OUTSIDE OF SHOWERS VSBYS IN BR WERE NOT FORECAST LOWER THAN 5SM. SHOWERS/ISOLD TSTMS COULD DVLP IN MOISTURE AHEAD OF FRONT THROUGH THIS MORNING BUT A SOMEWHAT INCREASE IN COVERAGE IS EXPECTED FM KLNK TOWARD KOMA THIS AFTN AS FRONT CROSSING AREA COMBINES WITH HIGHER MOISTURE. && .OAX WATCHES/WARNINGS/ADVISORIES...
