AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 355 PM CDT SUN AUG 21 2005 .DISCUSSION... MAIN FORECAST CHALLENGES REMAIN THE NEAR TERM HANDLING OF A BACKDOOR FRONT AS IT DRIFTS SE THROUGH THE AREA...AND THE TIMING OF ANOTHER FRONT LATER NEXT WEEK. MODELS HAVE DONE QUITE POORLY ON THE BACKDOOR FRONT...CONSISTENTLY ATTEMPTING TO PUSH IT THROUGH THE AREA WITH COOLER AND DRIER WEATHER TO FOLLOW. THE FRONT CURRENTLY LIES FROM NORTHEAST CORNER OF NEBRASKA TO SOMEWHERE SW OF DSM. COMBO OF DAYTIME HEATING AND CONVERGENCE AHEAD OF THE FRONT HAS RESULTED IN A BAND OF TSTMS. THESE SHOULD MIGRATE TOWARD THE SW THEN WEAKEN LATER TONIGHT IN ABSENCE OF LLJ. THERE MAY BE ENOUGH MID LEVEL MOISTURE IN SRN NEBRASKA TO KEEP SOME ACTIVINTY MOST OF THE NIGHT. ON THE OTHER HAND...IF THERE IS ENOUGH RADIATION THROUGH PARTLY CLOUDY SKIES THE HIGH DEW POINTS MAY ALLOW PATCHY FOG TO DEVELOP AGAIN IN THE SOUTHERN COUNTIES. THERE IS A LOT OF UNCERTAINTY ABOUT HOW FAR AND FAST THE FRONT WILL PUSH SW. PRESSURES HAVE BEEN RISING OVER MN...AND THIS SHOULD BE ENOUGH TO FORCE THE FRONT SOMEWHAT SW...ALTHOUGH LIKELY NOT AS FAR AS THE MODELS GIVE IT CREDIT. THUS...THERE MAY BE MORE THUNDERSTORMS DEVELOPING IN THE SW COUNTIES LATER MON AFTERNOON...BUT LOWER TEMPS THAN TODAY WILL INHIBIT CONVECTIVE DEVELOPMENT SOMEWHAT. AFTER A BRIEF PERIOD OF COOL DRY WEATHER THROUGH WED MORNING...WEATHER LATER IN THE WEEK SHOULD BE CONTROLLED BY THE SPEED OF THE NEXT APPROACHING FRONT. MODELS ARE IN GOOD AGREEMENT ON THE OVERALL SCENARIO OF A SHARP UPPER SYSTEM EJECTING OUT OF NRN ROCKIES INTO ONTARIO...BUT HAVE MAJOR PROBLEMS WITH THE TIMING. OPTED IN THE DIRECTION OF HPC IN SPEEDING THINGS UP A BIT. HOWEVER...WITH THE LEVEL OF UNCERTAINTY...THERE WAS NO POINT IN MAKING A LOT OF CHANGES. DID INCREASE POPS A BIT FOR THE PERIOD ON THURSDAY INTO THURSDAY NIGHT WHEN FRONT APPEARS MOST LIKELY TO BE PASSING THROUGH. NEXT WEEKEND WILL LIKELY START MILD AND DRY IN THE WAKE OF THE FRONT...BUT HEIGHTS RISE IN ADVANCE OF NEXT UPPER TROUGH DIGGING INTO THE PACIFIC NW. AGAIN...WITH TIMING UNCERTAINTIES...LEFT FORECAST DRY FOR NOW. WHILE THERE IS SOME CHANCE OF WARM ADVECTION IN ADVANCE OF THE NEXT SYSTEM...WARM ADVECTION SITUATIONS HAVE NOT BEEN VERY PRODUCTIVE OF LATE - AND THE SAME COULD EVEN BE SAID OF SEVERAL FRONTS. && .OAX WATCHES/WARNINGS/ADVISORIES...
