NWS Aberdeen, SD wrote its last area forecast discussion before the first event at Sep 7, 11:51 PM CST, 28 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE ABERDEEN SD 1251 AM CDT SUN SEP 8 2013 .UPDATE... SEE BELOW FOR AN UPDATED AVIATION FORECAST DISCUSSION. THE SEVERE THUNDERSTORM WATCH WAS EXPIRED AT 05Z. OVERALL FORECAST IS IN FAIR SHAPE AND DONT EXPECT TO MAKE ANY MAJOR CHANGES. SMALL COMPLEX OF STORMS OVER NORTHWEST SOUTH DAKOTA HAS HELD TOGETHER ON THE DEVELOPING NOCTURNAL LLJ. EAST OF THE MO RVR REMAINS A TOUGHER CALL AND REALLY AM NOT SURE IF THE AGGRESSIVE HRRR MODEL IS CORRECT. FOR NOW WILL STICK WITH SLIGHT CHC POPS EAST OF THE MO RVR AS LLJ IS NOT EXPECTED TO MIGRATE MUCH IF ANY EAST TNT. && .PREVIOUS DISCUSSION... .SHORT TERM...THROUGH TUESDAY AM A FEW WEAK...ELEVATED SHOWERS PASSING THROUGH THE CWA THIS PM...MAINLY ACROSS THE NORTHERN TIER ALL THANKS TO A SHORTWAVE MOVING THROUGH NORTH DAKOTA. ATMOSPHERE OVER THE CWA IS MARGINALLY UNSTABLE...SO WILL LEAVE IN LOW POPS...AGAIN FOR THE NORTHERN TIER. FOCUS SHIFTS WEST...WITH ANOTHER WEAK WAVE LIFTING OUT OF WYOMING. A 20-25KT LOW LEVEL JET WILL DEVELOP IN RESPONSE TO THIS FEATURE...WITH THE FOCUS IN FAR NORTHWEST SOUTH DAKOTA/WESTERN NORTH DAKOTA. WILL CONTINUE LOW POPS FOR FAR NORTHWEST COUNTIES IN CASE ANYTHING ELEVATED MANAGES TO TRICKLE INTO THE CWA. A LEE LOW/INVERTED TROF FORMS OVER CENTRAL SOUTH DAKOTA ON SUNDAY. VERY WARM MID LEVEL AIR...WITH H7 TEMPERATURES UPWARDS OF +15C MOVES INTO CENTRAL SOUTH DAKOTA...THOUGH TEMPERATURES ACROSS THE NORTHERN AND WESTERN PERIPHERY OF THE CWA ARE COOLER. STEEP LAPSE RATES AND WIND SHEAR ABOVE THE MIXED LAYER SUGGEST THE POTENTIAL FOR SEVERE STORMS...THE MAIN QUESTION BEING HOW FAR NORTH AND WEST DOES THE ELEVATED MIXED LAYER EFFECTIVELY CAP CONVECTION...AND JUST HOW FAR UNDER THAT CAP WILL THE SURFACE BOUNDARY SET UP. AT THIS POINT...THINKING IS THE CAP WILL HOLD...AND ANY CONVECTION THAT FIRES WILL EITHER BE ELEVATED OR VERY SHORT LIVED. BETTER CHANCES ARE EXPECTED AS THE SHORTWAVE GETS CLOSER TO THE CWA AND A NEARLY 50KT LOW LEVEL JET SET UP OVER THE CWA. STORMS WOULD LIKELY FORM ALONG THE NORTHERN PERIPHERY OF THE CWA WHERE JET CONVERGENCE IS GREATEST...WITH AN EAST/NORTHEAST MOTION. THE SURFACE FRONT WILL TAKE THROUGH MOST OF MONDAY TO EXIT THE CWA...WITH WEAK COLD ADVECTION AND GOOD MIXING IN ITS WAKE...EXPECT TEMPERATURES TO JUMP ABOVE NORMAL AGAIN FOR HIGHS MONDAY. ADVECTION IS NEUTRAL SO TEMPERATURES TUESDAY ABOUT THE SAME AS MONDAY. .LONG TERM...TUESDAY THROUGH SATURDAY MOST OF THE EXTENDED PERIOD LOOKS TO BE QUIET UNTIL THE FRIDAY AND SATURDAY TIME FRAME. TUESDAY STARTS OFF WITH NORTHWEST FLOW ALOFT AND DRY CONDITIONS AS THERE IS A LACK OF EMBEDDED WAVES IN THE UPPER LEVELS. SFC HIGH PRESSURE THEN BEGINS BUILDING SOUTH INTO THE AREA BY THURSDAY...BRINGING COOLER TEMPERATURES. AFTER HIGHS IN THE 80S TUESDAY AND WEDNESDAY...HIGHS SHOULD SLIP BACK INTO THE 70S FOR THURSDAY. MODELS THEN SHOW SHORTWAVE ENERGY MOVING INTO THE WESTERN DAKOTAS ON FRIDAY...WITH THE WAVE TRACKING ACROSS THE REST OF THE DAKOTAS FRIDAY NIGHT INTO SATURDAY MORNING. A SFC COLD FRONT SHOULD THEN MOVE EAST ACROSS THE AREA AT SOME POINT SATURDAY INTO SATURDAY EVENING. ALL THIS LEADS TO CHANCES FOR SHOWERS AND STORMS...INITIALLY ACROSS WESTERN AND CENTRAL SOUTH DAKOTA FRIDAY...THEN FOR THE REMAINDER OF THE AREA FRIDAY NIGHT AND SATURDAY. && .AVIATION... 06Z TAFS FOR THE KABR...KATY...KPIR AND KMBG TERMINALS A COMPLEX OF THUNDERSTORMS IS WORKING INTO THE KMBG TERMINAL. EXPECT SUB-VFR VISBIES IN HEAVY RAIN AND STRONG WINDS. ELSEWHERE...IF THIS CLUSTER OF STORMS CAN KEEP IT TOGETHER THROUGH 09Z...THE KABR TERMINAL WOULD BE NEXT TO POTENTIALLY RECEIVE SOME SUB-VFR FLYING WEATHER CONDITIONS IN THUNDER. AT THIS POINT...KPIR AND KATY MAY JUST GET BY WITHOUT A THUNDERSTORM THIS MORNING...AT LEAST PRIOR TO 12Z. WIDESPREAD MID/HIGH CLOUDS MAY PRECLUDE ANY MVFR GROUND FOG FROM GETTING GOING ACROSS THE REGION. BUT...WILL LEAVE IT IN FOR NOW AND ADJUST IN THE NEXT FEW HOURS. ANOTHER ROUND OF THUNDERSTORMS IS POSSIBLE LATER SUNDAY EVENING AND ON INTO THE OVERNIGHT HOURS. THE KMBG AND KABR TERMINALS STAND THE LARGEST PROBABILITY OF RECEIVING SOME OF THIS POTENTIAL CONVECTION. && .ABR WATCHES/WARNINGS/ADVISORIES... SD...NONE. MN...NONE. && UPDATE...DORN SHORT TERM...CONNELLY LONG TERM...TMT AVIATION...DORN WEATHER.GOV/ABERDEEN
