Area forecast discussion, May 8, 2:00 AM CST, 12 hours 35 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 300 AM CDT SUN MAY 8 2005 .DISCUSSION... MAIN FORECAST CHALLENGES WILL BE STRENGTH AND COVERAGE OF CONVECTIVE DEVELOPMENT TODAY...THEN CHANCES FOR PRECIP BEGINNING MID WEEK AS THE NEXT STRONG AREA OF LOW PRESSURE MOVES ONTO THE PLAINS. IN THE SHORT TERM...CONVECTION ACROSS NORTHEAST NEBRASKA IN ITS LAST STAGES AS CLOUD TOPS CONTINUE TO WARM AND LOW LEVEL JET CONTINUES TO SLOWLY WEAKEN. A FAIR AMOUNT OF LOW CLOUDS WILL START THE DAY WITH THE COLD FRONT POISED ACROSS CENTRAL NEBRASKA. FEEL THE LOWER CLOUDS SHOULD SCATTER OUT THROUGH THE MORNING ALLOWING SUNSHINE TO CONTINUE THE DESTABILIZATION PROCESS SETTING THE STAGE FOR QUITE AN WEATHER DAY LATER THIS AFTERNOON AND EVENING. WHILE IT SHOULDNT BE AS WINDY AS IT WAS YESTERDAY...IT SHOULD STILL BE WELL INTO THE BREEZY CATEGORY NONETHELESS. AS WE MOVE THROUGH PEAK HEATING...PW VALUES INCREASE TO 1.25 INCHES AND H85 DEWPOINTS INCREASE TO +11 OR +12. WITH A PLUME OF VERY STEEP LAPSE RATES OVERSPREADING THE PLAINS...CAPE VALUES APPROACH 2500 TO 3000 J/KG BY MID AFTERNOON ALONG AND AHEAD OF THE FRONT. WHILE 0-6KM BULK SHEAR VALUES REMAIN SOMEWHAT WEAK AROUND 25 KNOTS...STRONG INSTABILITY CAN OVERCOME WEAK SHEAR RESULTING IN NUMEROUS SEVERE STORMS. TOTAL TOTAL INDICES REACH 62 TO 64, LIFTED INDICES REACH -8 TO -10, AND K INDICES REACH 36 TO 40. WET BULB ZERO VALUES ARE 8000 TO 9000 FEET, AN IDEAL RANGE FOR VERY LARGE HAIL. IN FACT...THERE APPEARS TO BE VERY LITTLE CIN/CAP THIS AFTERNOON ALLOWING FOR RAPID DEVELOPMENT BY 19Z TO 21Z AS A FIRST GUESS. WOULD PREDICT THAT AT LEAST A SEVERE THUNDERSTORM WATCH WILL BE NEEDED LATER TODAY FOR AT LEAST A PART OF CWA FROM MID AFTERNOON THROUGH LATE EVENING FOR LARGE HAIL AND DAMAGING WIND GUSTS. WE SHOULD SEE A DECREASING TREND FROM WEST TO EAST AFTER MIDNIGHT WITH THUNDERSTORMS MOVING EAST OF THE REGION BY 08Z TO 10Z OR THEREABOUTS. FOR MONDAY...HAVE REMOVED THE MENTION OF PRECIPITATION AS THE SURFACE TROUGH PUSHES TO THE MISSOURI RIVER BY 12Z MONDAY. THUS...ANY DEVELOPMENT AHEAD OF THE TROUGH WILL BE ACROSS CENTRAL IOWA...WHILE THE CLOSED SURFACE LOW SHOULD BE FAR ENOUGH NORTH TO KEEP ANY WRAPAROUND MOISTURE NORTH OF THE CWA IN THE DAKOTAS. IT WILL ALSO BE A COOLER DAY WITH TEMPS ONLY IN THE 60S TO LOWER 70S. IN THE EXTENDED FORECAST...FOCUS SHIFTS TO THE NEXT STRONG AREA OF LOW PRESSURE AND RESULTANT WEATHER TRENDS FROM MID WEEK THROUGH THE FIRST HALF OF NEXT WEEKEND. THERE WILL LIKELY BE NUMEROUS FORECAST CHALLENGES WITH THIS NEXT SYSTEM...WHICH COULD LEAD TO WILD SWINGS IN EXPECTED WEATHER. AT THE PRESENT TIME...THE NAM AND GFS ARE HANDLING THE SYSTEM QUITE DIFFERENTLY WITH REGARD TO QPF DESPITE SIMILAR MASS FIELDS. THE NAM IS FOCUSING MORE OF THE ENERGY ALONG A WARM FRONT THAT WOULD LEAD TO PRECIP FURTHER SOUTH ACROSS PORTIONS OF NEBRASKA AS EARLY AS TUESDAY AFTERNOON AND NIGHT. MEANWHILE...THE GFS IS FOCUSING ITS ENERGY FURTHER NORTH WHICH WOULD SUPPRESS MOST OF THE PRECIP IN OUR AREA UNTIL WEDNESDAY NIGHT. FOR NOW...GIVEN UNCERTAINTIES IN THE MODEL RUNS...WILL STICK CLOSER TO A GFS AND CANADIAN SOLUTION AND WILL NOT BUY INTO THE NAM JUST YET. WHERE EXACTLY THE FRONTAL BOUNDARY SETS UP COULD ALSO HAVE A LARGE IMPACT ON TEMPERATURES YIELDING SOME SIGNIFICANT BUST POTENTIAL MID WEEK AS WELL. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...NONE.
