AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OMAHA/VALLEY NE 623 PM CDT SUN JUL 7 2013 .DISCUSSION... SEVERE THUNDERSTORM WATCH WAS ISSUED FOR NORTHEAST NEBRASKA FOR THE REMAINDER OF THE EVENING. A WEAK STATIONARY FRONT REMAINS IN PLACE IN THE REGION...WITH STRONGER SEVERE CONVECTION JUST NORTHWEST OF THE FORECAST AREA IN NORTHERN NEBRASKA AND SOUTHEAST SOUTH DAKOTA. HIRES MODELS SUGGEST THIS ACTIVITY SHOULD CONTINUE TO REMAIN STRONG THROUGH THE EVENING AS IT PUSHES EAST SOUTHEAST... TAKING ADVANTAGE OF AN EXTREMELY UNSTABLE AIR MASS WITHIN AN AREA THAT HAS FAVORABLE WIND SHEAR. && .AVIATION...00Z TAFS FOR KOMA...KLNK AND KOFK. MAIN CONCERN WILL BE TIMING CONVECTION INTO AND OUT OF THE TAF SITES TONIGHT. BEST GUESS WOULD BE AROUND 03-07Z AT KOFK...AND 05-10Z AT KLNK/KOMA. OTHERWISE...VFR CONDITIONS PREVAIL. DEWALD && .PREV DISCUSSION... /ISSUED 305 PM CDT SUN JUL 7 2013/ DISCUSSION... TYPICAL MID SUMMER PATTERN LOOKS TO BE IN PLACE FOR THE SHORT TERM PERIOD WITH WEAK SURFACE FEATURES AND BROAD UPPER HIGH PRESSURE OVER THE SOUTHERN PORTION OF THE NATION...WHILE STRONGER AND MORE ACTIVE FLOW STAYS OVER THE NORTHERN PLAINS. ALTHOUGH MOISTURE AND INSTABILITY WILL BE IN PLACE OVER THE AREA FOR THE PERIOD EXPECT ONLY ISOLATED CONVECTION FOR THE MOST PART WITH NIGHTTIME PERIODS SEEING BEST CHANCE OF MORE WIDESPREAD ACTIVITY. MAIN AREA OF CONVECTION AT 19Z WAS OVER CENTRAL SOUTH DAKOTA WITH A SECOND BAND OF STORMS ALONG THE NORTHERN NEBRASKA BORDER NEAR KVTN. THIS ACTIVITY INDICATED TO SPREAD EAST BY THE SHORT RANGE MODELS INTO THIS EVENING WITH ADDITIONAL AND MORE EXTENSIVE DEVELOPMENT ACROSS SOUTHERN PARTS OF NEBRASKA LATER TONIGHT. SOMEWHAT COOLER AIR INDICATED FOR LATE IN THE PERIOD ON WEDNESDAY AS STRONGER WAVE MOVES THROUGH THE UPPER MIDWEST AND UPPER HIGH SHIFTS TO THE WEST. UPPER PATTERN BECOMES MORE COMPLEX IN THE EXTENDED PERIOD AS A TROUGH DIGS OVER THE EASTERN CONUS WITH CLOSED LOW DEVELOPING OVER THE SOUTHEAST BY THE WEEKEND. THIS FEATURE THEN TRANSLATES WEST TOWARDS TEXAS WITH UPPER HIGH SHIFTING NORTH. THIS SHOULD KEEP MAIN FOCUS FOR STORMS TO THE SOUTH BUT HAVE KEPT SOME LOWER POPS IN THE FORECAST FOR OVERNIGHT PERIODS DURING THIS TIME DUE TO LIMITED CONFIDENCE IN MODELS. && .OAX WATCHES/WARNINGS/ADVISORIES...
