NWS Omaha, NE wrote its last area forecast discussion before the first event at Jul 20, 8:44 PM CST, 1 hour 43 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 944 PM CDT WED JUL 20 2005 .DISCUSSION... HAVE UPDATED ZONES TO REFLECT CURRENT TRENDS WITH CLUSTER OF STORMS OVER NORTH CENTRAL NEBRASKA THIS EVENING. EXPECT AMPLE MOISTURE AND INSTABILITY WILL COMBINE WITH LOW LEVEL FORCING THROUGH THE NIGHT TO HELP SUSTAIN CONVECTION OVER NORTHEAST NEBRASKA SHORTLY AFTER MIDNIGHT...DESPITE QUITE WARM MID LEVEL TEMPS. THESE STORMS HAVE HAD A HISTORY OF PRODUCING BASEBALL SIZE HAIL OVER SOUTH CENTRAL SOUTH DAKOTA. NOT SO SURE THAT WILL HAPPEN OVER THE CWA...BUT SOME LARGE HAIL IS DEFINITELY POSSIBLE ALONG WITH DAMAGING WINDS. THE LATEST RUC THOUGH INDICATES THAT CAPPING EFFECTS WILL STRENGTHEN INTO EAST-CENTRAL AND SOUTHEAST NEBRASKA WITH TIME...AND EXPECT ACTIVITY WILL WEAKEN BY THEN. && DEE .PREV DISCUSSION... 240 PM CDT WED JUL 20 2005 MAIN FORECAST CHALLENGES WILL BE TIMING OF PRECIP OVER THE NEXT COUPLE OF DAYS AND RESULTANT MAX TEMPERATURES AND EXACTLY WHERE THE BOUNDARIES WILL SET UP. IN THE SHORT TERM...12Z UPPER AIR ANALYSIS INDICATED VERY SUBTLE SHORTWAVE MOVING INTO THE NORTHERN ROCKIES WITH 10M HEIGHT FALLS NOTED...ALONG WITH A 60KT SPEED MAX. THIS WILL LIKELY CONTRIBUTE TO CONVECTIVE INITIATION...MOSTLY LIKELY ACROSS EASTERN SOUTH DAKOTA AHEAD OF ALONG A COLD FRONT EDGING SOUTHWARD. H70 TEMPERATURES INDICATED WE WERE WELL CAPPED...THUS WELL LIKELY HAVE TO WAIT UNTIL TONIGHT FOR CONVECTION TO REALLY GET GOING...MAINLY ACROSS NORTHEAST NEBRASKA. WHATEVER MCS DEVELOPS WILL LIKELY SLIDE EAST SOUTHEAST AND MOVE INTO IOWA...AND COULD POSSIBLY LINGER ALONG AND EAST OF THE MISSOURI RIVER THURSDAY MORNING...IN SIMILAR FASHION TO WHAT HAPPENED TODAY. NEVERTHELESS...THIS WILL HAVE A LARGE IMPACT ON FORECAST HIGHS FOR THURSDAY...WITH POINTS NORTH OF I80 ON THE COOLER SIDE AND POINTS OFF TO THE SOUTH STILL VERY HOT WITH HIGHS NEAR 100 AGAIN. ELEVATED DEWPOINTS WILL CONTRIBUTE TO HEAT INDICES ABOVE 105. OFFICIALLY...TO ISSUE A HEAT ADVISORY...WE ALSO NEED NIGHTTIME LOWS AROUND 80 OR ABOVE. THUS...WERE NOT EXPECTING TO MEET THOSE CONDITIONS WITH LOWS IN THE MID TO UPPER 70S...THEREFORE WELL CONTINUE TO MENTION HEAT INDEX VALUES IN THE ZFP AND HIGHLIGHT THE IMPACTS IN THE HWO. THE FORECAST FOR THURSDAY NIGHT SEEMS SIMILAR TO WHAT WERE EXPECTING TONIGHT...WITH THE RING OF FIRE REDEVELOPING IN SIMILAR FASHION AS IT DOES TONIGHT. THE SURFACE LOW WILL REMAIN ACROSS CENTRAL PORTIONS OF NEBRASKA WITH A SIGNIFICANT CAP EXPECTED FOR THE DAYLIGHT HOURS...BUT SHOULD SEE ANOTHER MCS DEVELOP INTO NORTHEAST NEBRASKA THURSDAY NIGHT AND ROLL EAST SOUTHEAST TOWARD IOWA. THIS SECOND MCS PERHAPS DEVELOPS JUST A BIT FURTHER DEEPER INTO OUR CWFA THOUGHT. THIS WILL AGAIN DRIVE THE SURFACE BOUNDARY INTO OUR CWA AND COULD POSE QUITE A CHALLENGE IN DEFINING TEMPERATURES. AGAIN AM EXPECTING COOLER TEMPS ACROSS NORTHEAST NEBRASKA WITH WARMER TEMPERATURES TO THE SOUTHWEST. SATURDAY IS SHAPING UP TO BE THE HOTTEST DAY OF THE PERIOD AS THE SURFACE LOW REDEVELOPS WELL TO OUR NORTHWEST ACROSS SOUTH DAKOTA. LOOKING FOR HIGHS AT OR ABOVE 100 FOR JUST ABOVE ALL AREAS WITH DRY CONDITIONS. SUNDAY SHOULD BE QUITE SIMILAR...BUT PERHAPS JUST A BIT COOLER ACROSS NORTHEAST NEBRASKA AS ANOTHER SURFACE BOUNDARY BEGINS TO MOVE IN. MONDAY APPEARS TO BE SIMILAR TO SUNDAY...BUT MAYBE A DEGREE OR TWO COOLER BASED ON JUST A FEW MORE CLOUDS EXPECTED. WE MAY EVENTUALLY NEED TO ISSUE A HEAT ADVISORY FOR SATURDAY THROUGH SUNDAY AS NIGHTTIME LOWS DURING THAT TIME WILL LIKELY BE IN THE UPPER 70S TO NEAR 80. LOOKS LIKE RELIEF IS IN SIGHT AS THE AFOREMENTIONED BOUNDARY FINALLY MAKES A DECENT PUSH INTO THE CWFA MONDAY NIGHT. THAT LOOKS LIKE OUR NEXT BEST CHANCE FOR PRECIPITATION (BEYOND THE SYSTEMS THAT DEVELOP TONIGHT AND THURSDAY NIGHT). THE FRONT PUSHES WELL SOUTH OF THE REGION BY TUESDAY AND WEDNESDAY...WITH HIGHS FALLING BACK INTO THE MID TO UPPER 80S...EVEN SLIGHTLY BELOW NORMAL. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...NONE.
