NWS Omaha, NE wrote its last area forecast discussion before the first event at Aug 7, 1:55 PM CST, 9 hours 5 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 255 PM CDT MON AUG 7 2006 .DISCUSSION... MAIN FORECAST CHALLENGE TONIGHT WILL BE REDEVELOPMENT OF HEAVY RAIN ACROSS SOUTHERN CWFA AS YET ANOTHER IMPULSE EJECTS OUT OF NORTHEASTERN COLORADO AND MOVES NORTH OF THE FRONTAL BOUNDARY. THE STATIONARY FRONT ITSELF WILL REMAIN ACROSS CENTRAL KANSAS THROUGH NORTHEAST MISSOURI. WE COULD SEE ISOLATED STORMS FIRE JUST NORTH OF THE BOUNDARY NEAR THE KANSAS BORDER ONCE AGAIN THIS AFTERNOON...BASED ON AGITATED CU FIELD JUST WEST OF KCNK. OTHERWISE...MOISTURE SEEMS TO BE POOLING ALONG AND NORTH OF THE FRONT OVERALL...AND AS LOW LEVEL JET DEVELOPS TONIGHT AND BACKS IN RESPONSE TO APPROACHING WAVE...THE H85 FRONT SHOULD TIGHTEN UP WITH RAIN AND EMBEDDED THUNDERSTORMS REDEVELOPING BY LATE EVENING ACROSS SOUTH CENTRAL NEBRASKA. THE NAM/GFS ARE SIMILAR IN THIS REGARD... ALTHOUGH THE NAM IS LIKELY TOO FAR NORTH WITH THE MCS DEVELOPMENT GIVEN THE DRIER AIR THAT EXISTS IN NORTHEAST NEBRASKA. WHILE THE GFS HAS EXPERIENCED SIGNIFICANT CONVECTIVE FEEDBACK WITH JUST ABOUT EVERY EVENT LATELY...THE LOCATION OF THE PRECIP ACTUALLY HASN/T BEEN THAT FAR OFF...JUST THAT THE AMOUNTS HAVE BEEN OVERESTIMATED. WITH THAT IN MIND...WILL INCREASE POPS HOURLY THROUGH THE NIGHT WITH 60 TO 80 PERCENT POPS ONCE AGAIN SETTING UP FOR AREAS ALONG AND SOUTH OF THE INTERSTATE BY DAYBREAK. THE NORTHERN EXTENT OF THE RAIN WILL BE THE TRICKY PART AS DRIER AIR WILL HAVE SOME INFLUENCE...BUT AT LEAST A CHANCE WILL EXIST ALL THE WAY TO THE SOUTH DAKOTA BORDER. FOR TUESDAY...THE MCS THAT DEVELOPS TONIGHT WILL CONTINUE TO PUSH EASTWARD INTO IOWA AND MISSOURI LEAVING BEHIND QUITE A BIT OF CLOUDINESS AND COOL TEMPERATURES ONCE AGAIN. THERE COULD BE A LINGERING CHANCE OF THUNDERSTORMS IN THE AFTERNOON AND EARLY EVENING BEFORE ENDING AND PUSHING EAST ALTOGETHER. TOTAL RAINFALL AMOUNTS FOR THE 24 HOUR PERIOD THROUGH 00Z WEDNESDAY COULD RANGE FROM ONE QUARTER INCH NEAR THE SOUTH DAKOTA BORDER TO TWO INCHES NEAR THE KANSAS BORDER. REALLY THERE ARE ONLY TWO COUNTIES THAT WE/LL MONITOR FOR ANY FLOODING...INCLUDING JEFFERSON AND GAGE...BOTH OF WHICH HAD EXTREMELY HEAVY RAINS YESTERDAY EVENING WHERE 6 HOUR FLASH FLOOD GUIDANCE VALUES REMAIN BELOW 2 INCHES. FOR WEDNESDAY...IT SHOULD REMAIN DRY WITH TEMPERATURES BEGINNING TO WARM BACK INTO THE 90S WHILE WE WAIT FOR THE NEXT SYSTEM AND ASSOCIATED FRONT TO ROLL SOUTHWARD OUT OF THE DAKOTAS...BUT NOT UNTIL WEDNESDAY NIGHT. THUS...REMOVED THE CHANCE OF RAIN FOR WEDNESDAY AFTERNOON THAT WAS PREVIOUSLY MENTIONED. FOR THE EXTENDED FORECAST FROM THURSDAY THROUGH MONDAY. THE PREVIOUSLY MENTIONED FRONTAL BOUNDARY WILL BE MOVING THROUGH THE CWFA THROUGH THE DAY THURSDAY...THEN SOUTH AND OUT OF THE AREA THURSDAY NIGHT. AHEAD OF THE FRONT...IT WILL BE ANOTHER HOT DAY WITH HIGHS IN THE MID TO UPPER 90S AND UNCOMFORTABLE HUMIDITY VALUES ONCE AGAIN AS DEWPOINTS COME BACK INTO THE LOW TO MID 70S. WILL MAINTAIN AT LEAST A SLIGHT CHANCE OF THUNDERSTORMS ALONG THE FRONT THURSDAY NIGHT SOUTHERN CWFA...WHICH SHOULD CLEAR THE REGION BY DAYBREAK FRIDAY. BOTH FRIDAY AND SATURDAY SHOULD BE DRY AS WE WAIT FOR THE NEXT WEATHER DISTURBANCE WHICH WILL BE MOVING THROUGH THE PACIFIC NORTHWEST. BOTH DAYS WILL BE WARM DAYS WITH HIGHS GENERALLY IN THE LOWER 90S...THOUGH NOT AS HOT AS WE/LL SEE ON THURSDAY. THE TROUGH TO OUR NORTHWEST WILL MOVE INTO THE NORTHERN CONUS LATE SATURDAY THROUGH SUNDAY WHICH SHOULD BEGIN TO DRIVE A FRONT INTO THE REGION THROUGH THIS TIME. HELD OFF ON ANY PRECIP UNTIL SATURDAY NIGHT...WITH A SLIGHTLY BETTER CHANCE OF STORMS ON SUNDAY. THE 00Z GFS WAS A LITTLE MORE AGGRESSIVE IN BRINGING THIS SYSTEM IN LATE SATURDAY AFTERNOON RATHER THAN SATURDAY NIGHT. THUS...THE 00Z GFS ENSEMBLE MEAN IS A GOOD COMPROMISE FOR THIS SYSTEM. THERE IS SOME QUESTION WHETHER OR NOT THE REAL FRONT WILL ACTUALLY BE ABLE TO PASS SOUTHWARD THROUGH THE REGION...BUT FOR NOW...THINK THE FRONT WILL EITHER TREK SOUTH OR WASH OUT MONDAY...LEAVING THE FIRST PART OF NEXT WEEK SOMEWHAT PLEASANT WITH HIGHS IN THE MID 80S AND MUCH LOWER HUMIDITY. && .OAX WATCHES/WARNINGS/ADVISORIES...
