AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA NATIONAL WEATHER SERVICE SIOUX FALLS SD 332 PM CDT WED JUL 14 2010 .DISCUSSION... BAND OF ACCAS SHOWERS AND ISOLATED THUNDERSTORMS SWINGING THROUGH THIS AFTERNOON DOING LITTLE MORE THAN PRODUCING SPRINKLES. ACCAS BASED BETWEEN 12-14 KFT WITH AN ABUNDANCE OF VERY WARM AND DRY AIR BELOW...SO ANY PRECIPITATION THAT CAN DEVELOP HAVING A REALLY HARD TIME MAKING IT TO THE SFC. WILL CONTINUE THE THREAT FOR ISOLATED SEVERE THUNDERSTORMS OVER SOUTHERN PARTS OF NW IA...ALTHOUGH THE THREAT APPEARS TO BE WANING AS THE BAND OF ACCAS SHOWERS MOVES IN. A PRETTY GOOD CHANCE THAT LITTLE IF ANYTHING WILL BE OCCURRING ACROSS THE CWA AFTER 0Z...AND WILL ONLY HAVE A 20-40 PERCENT CHANCE ALONG AND SOUTH OF A SUX TO SLB LINE. OTHERWISE...DEW POINTS WILL CONTINUE TO DROP THROUGH THE EVENING AND OVERNIGHT. DEW POINTS INTO THE MID 40S IN CENTRAL SD WITH GOOD AFTERNOON MIXING...SO DO NOT EXPECT THEM TO FALL THIS LOW...BUT BACK INTO THE 50S AND LOWER 60S BY THURSDAY MORNING. WITH SOME NORTHWEST WIND THROUGH THE NIGHT...EXPECT LOWS FROM THE MID 50S TO LOWER 60S. /08 TEMPS SHOULD JUMP INTO THE MID AND UPPER 80S ON THURSDAY DURING A SHORT LIVED BREAK FROM HUMIDITY...WITH DECENT MIXING AND WARMING H85 TEMPS. OVERARCHING NW FLOW WILL KEEP WX QUIET THRU FRI MORNING...HOWEVER AS RETURN FLOW BEGINS ON FRI AFTN...COULD SEE A FEW TSTMS POPPING UP IN S CENTRAL SD WITH SFC HEATING AND DECENT LOW LEVEL LAPSE RATES. THREAT FOR ISOLD TSTMS WILL INCREASE EASTWARD AS LLJ KICKS UP DURING THE EVENING HRS...HOWEVER PROBABILITY IS STILL FAIRLY LOW DUE TO LACK OF MOISTURE AT LOW LEVELS. A REAL RETURN TO STICKY DEWPOINTS COMES WITH INCREASING SOUTHERLY WINDS ON SATURDAY. WINDS SHOULD BE FAIRLY GUSTY AHEAD OF THE SFC COLD FRONT AND WILL ADVECT QUITE A BIT OF LOCAL MOISTURE UP FROM NEBRASKA. MODELS IN FAIRLY GOOD AGREEMENT WITH PRESENCE AND TIMING OF SFC FRONT...WHICH IS STILL SUPPORTED BY AN UPPER WAVE. BUMPED POPS UP TO LIKELY IN MUCH OF THE FA FOR SUNDAY NIGHT...WITH A LITTLE MORE UNCERTAINTY FURTHER SOUTH. LOOKS LIKE IT WILL BE PRIMARILY A NOCTURNAL EVENT...BUT HAVE SOME TRAILING POPS INTO SUNDAY MORNING FOR ANY LINGERING SHOWERS. LARGE SCALE PATTERN BECOMES MORE ZONAL AND THEN SOUTHWESTERLY INTO NEXT WEEK...AND LOOKS LIKE A SIGNIFICANT WARM UP IS ON THE WAY BEGINNING WEDNESDAY. KEPT TEMPS A LITTLE COOLER ON MONDAY AND TUESDAY AGAIN DUE TO EASTERLY FLOW NEAR THE SURFACE...WHICH WILL MAKE DAYTIME HEATING A LITTLE MORE DIFFICULT. GUESSING THAT GUIDANCE WILL TREND UPWARD ON TEMPS FOR WEDNESDAY AS IT COMES A LITTLE CLOSER...AND HAVE GONE ABOVE GUIDANCE FOR THAT DAY IN ATTEMPT TO FCST THE FCST. TSTM DEVELOPMENT NOT OUT OF THE QUESTION ANY NIGHT IN THE EXTENDED IN RIDGE RIDER PATTERN...BUT LOWERED GUIDANCE POPS CONSIDERABLY...ATTEMPTING TO NARROW DOWN THE THREAT WITH SCHC POPS ON MON AND TUES NIGHTS. 12Z RUN OF THE GFS IS PRETTY EXCITED ABOUT TUESDAY NIGHT...BUT WILL WAIT FOR A LITTLE BETTER TIME CONTINUITY BEFORE JUMPING ON THE BANDWAGON WITH HIGHER POPS. ALSO LOOKS PRETTY BREEZY WITH A GOOD GRADIENT THROUGH THE AREA ON TUES NIGHT AND WED...WHICH WILL AID IN RAISING THE TEMPS IN THE LATTER PORTION OF THE EXTENDED. /LAFLIN && .AVIATION... SOME PATCHY SHORT LIVED MVFR CLOUD COVER POSSIBLE THROUGH ABOUT 0Z TODAY...THEN VFR THROUGH TOMORROW AFTERNOON. STILL A SMALL THREAT FOR THUNDERSTORMS AROUND KSUX THROUGH ABOUT 0Z AS WELL. /08 && .FSD WATCHES/WARNINGS/ADVISORIES... SD...NONE. MN...NONE. IA...NONE. NE...NONE. && 08/LAFLIN
