NWS Aberdeen, SD wrote its last area forecast discussion before the first event at Jun 14, 9:29 AM CST, 3 hours 52 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE ABERDEEN SD 1029 AM CDT TUE JUN 14 2011 .UPDATE... ADDED SOME SCATTERED SHOWERS TO THE FAR NE COUNTIES THIS MORNING TO REFLECT CURRENT RADAR TRENDS. ALSO INCREASED POPS ACROSS CORSON/DEWEY COUNTIES FOR TSTORMS THAT ARE CURRENTLY TRAINING OVER THE AREA. THESE SHOWERS AND TSTORMS IN THE WEST THAT ARE ASSOCIATED WITH A N-S ORIENTED SFC TROF WILL SLOWLY PUSH EAST THROUGH THE DAY. SEE BELOW FOR UPDATED AVIATION DISCUSSION. && .PREVIOUS DISCUSSION... .SHORT TERM...TODAY THROUGH THURSDAY THE THREAT OF SEVERE STORMS TODAY WILL BE THE MAIN FORECAST CHALLENGE. AS OF 7Z...AN OPEN WAVE AT H5 IS MOVING THROUGH THE NORTHERN ROCKIES. AHEAD OF THE MID LEVEL TROF WILL BE A NORTH/SOUTH AXIS OF MODERATE INSTABILITY WITH SURFACE DEW POINTS IN THE LOWER 60S. WITH THE LACK OF MOISTURE ADVECTION...THE DEW POINTS MAY NOT INCREASE VERY MUCH TODAY. HOWEVER EVEN WITH A SLIGHT INCREASE SURFACE BASE CAPE VALUES SHOULD RANGE BETWEEN 1000-1500 J/KG...WITH MU-CAPE VALUES AROUND 1700 J/KG. WHILE THESE CAPE VALUES ARE DECENT FOR SEVERE WEATHER...0-6 KM BULK SHEAR VALUES ARE FAIRLY WEAK...OR AROUND 25 KNOTS. BASED ON THE AMOUNT OF INSTABILITY AND WEAK SHEAR...BELIEVE A FEW THUNDERSTORMS MAY BECOME STRONG TO SEVERE LATER THIS AFTERNOON WITH THE MAIN THREAT BEING HAIL UP TO ONE INCH. ONE AREA OF CONCERN IS THE POSSIBILITY OF LOCALLY HEAVY RAINFALL WITH SOME THUNDERSTORMS. WHILE PWATS ARE AROUND 1.30 INCHES...STORM MOTION IS SHOWN TO AVERAGE AROUND 10 KNOTS. EVEN CORFIDI VECTORS AHEAD OF THE MID LEVEL TROF ARE FAIRLY SHORT. WILL LEAVE OUT THE MENTION OF LOCALLY HEAVY RAINFALL FOR NOW...BUT IT WILL BE SOMETHING THE DAY SHIFT MAY CONSIDER ADDING TO THE MORNING UPDATE. WHILE DRIER AIR WILL FILTER INTO THE REGION ON WEDNESDAY...THE COMBINATION OF STEEP LOW LEVEL LAPSE RATES AND MODERATE INSTABILITY...BELIEVE THE NE CWA COULD SEE AFTERNOON THUNDERSTORMS. THERE WILL BE TWO LIMITING FACTORS FOR CONVECTION FOR THE REST OF THE CWA. THE FIRST IS WAA IN THE MID LEVELS AND THE SECOND IS EXTREMELY DRY AIR PUSHING INTO THE MID LEVELS. AN UPPER LEVEL RIDGE BRIEFLY BUILDS INTO THE REGION ON WEDNESDAY NIGHT THROUGH THURSDAY. THIS UPPER LEVEL RIDGE WILL BRING WARMER TEMPERATURES TO THE NORTHERN PLAINS...ALONG WITH INCREASING LLM. WITH THE INCREASE IN LLM...MU-CAPE VALUES OFF THE GFS ARE SHOWN TO REACH OVER 3000 J/KG BY 0Z FRIDAY. SINCE THE GFS IS THE ONLY MODEL AT THIS TIME SHOWING VERY HIGH MU-CAPE VALUES...WILL LEAVE THE THURSDAY TIME PERIOD DRY FOR NOW. .LONG TERM...THURSDAY NIGHT THROUGH MONDAY UPPER LEVEL RIDGING WILL JUST BE SLIDING EAST OF THE REGION THURSDAY NIGHT...WITH A TROUGH DIGGING DOWN THE WEST COAST. A SERIES OF SHORTWAVES WILL TRACK OVER THE NORTHERN PLAINS IN SOUTHWEST FLOW AS THE TROUGH SLOWLY PUSHES EASTWARD. BY MONDAY MORNING...THE TROUGH WILL BE CENTERED OVER THE WESTERN DAKOTAS...THEN THE LOW WRAPS UP OVER THE NORTHERN PLAINS. GENERALLY LOOKING AT UPPER LEVEL ENERGY OVER THE REGION THROUGHOUT THE PERIOD. AT THE SURFACE...A BROAD AREA OF LOW PRESSURE WILL REMAIN SITUATED OVER THE NORTHERN AND CENTRAL PLAINS...WITH THE SURFACE LOW ALSO WRAPPING UP OVER THE FAR NORTHERN PLAINS ON MONDAY. THE AREA OF LOW PRESSURE IN ASSOCIATION WITH THE SERIES OF UPPER LEVEL SHORTWAVES MAKES IT ALMOST IMPOSSIBLE TO PINPOINT A TIME PERIOD WHERE IT WILL BE DRY...SO WILL STICK WITH CHANCE POPS ALL PERIODS. MODELS CONTINUE TO SHOW INSTABILITY AS WELL...SO WILL KEEP THE PRECIPITATION MENTION AS SHOWERS AND THUNDERSTORMS. TEMPERATURES WILL CONTINUE TO BE RIGHT AROUND NORMAL...WITH H85 TEMPS IN THE TEENS TO LOWER 20S. GENERALLY LOOKING AT DAYTIME HIGHS IN THE MID TO UPPER 70S...AND OVERNIGHT LOWS IN THE UPPER 50S TO LOWER 60S. && .AVIATION... TAFS FOR THE KABR...KATY...KPIR AND KMBG TERMINALS SCT-BKN VFR CIGS WILL GENERALLY REMAIN OVER THE AREA THROUGH THE REST OF THE DAY. FOG HAS DISSIPATED ACROSS THE EASTERN CWA. HOWEVER...THE WESTERN CWA WILL CONTINUE TO DEAL WITH SOME IFR/MVFR FOG AND LOW CLOUDS LATE THIS MORNING...POSSIBLY INTO EARLY AFTERNOON...BEFORE FLYING WEATHER CONDITIONS IMPROVE. SHOWERS AND THUNDERSTORMS ARE DEVELOPING ACROSS WESTERN AND PORTIONS OF NORTH CENTRAL SOUTH DAKOTA...AND WITH SOME DAYTIME HEATING ADDITIONAL SHOWER AND THUNDERSTORM DEVELOPMENT IS EXPECTED LATER THIS AFTERNOON AND EVENING...WITH PERIODS OF IFR/MVFR CIGS AND VSBYS POSSIBLE WITHIN AREAS OF HEAVIER RAINFALL. && .ABR WATCHES/WARNINGS/ADVISORIES...
