AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA NATIONAL WEATHER SERVICE SIOUX FALLS SD 500 AM CDT THU JUN 10 2010 .DISCUSSION... LARGE AND ORGANIZED MCS ROLLING ACRS NEBRASKA THIS MORNING...NUDGING INTO FAR SRN SD. MCS IS LOCATED IN THE MAX OF MOISTURE TRANSPORT AXIS FROM 925-850 HPA...COLLOCATED WITH STRONGEST AXIS OF LLJ. MOST OPERATIONAL GUIDANCE HAS HAD A SIGNIFICANT NORTH BIAS WITH AXIS OF PRECIP...BUT AGAIN THE RAPID REFRESH RUC HAS HAD AN EXCELLENT HANDLE ON THE CONVECTIVE MODE/LOCATION WITH 03Z-06Z RUNS...AND LENDS CONFIDENCE TO THE SHORT RANGE FCST. HOWEVER...CHALLENGE INCREASES TO NEARLY EVERY FCST ELEMENT AS CONVECTION IN MODELS REALLY LIMIT USEFULNESS TO DIAGNOSE THE SVR ENVIRONMENT TODAY...AS WELL AS BOUNDARY LOCATION FOR THERMAL FCST AND CONVECTIVE REDEVELOPMENT. MCS WL CONTINUE TO ROLL GENERALLY EWRD THIS MORNING BASED ON CORFIDI VECTORS...BUT THERE IS INCREASING LLJ SUPPORT FOR DEVELOPMENT OF WAA WING INTO MUCH OF CWA IN THE EARLY TO MID MORNING AS WAVE TRAVERSING RIDGE INDUCES A VEERING TO LLJ. SPED UP POPS...AND INCREASED MOST OF THE W AND S TO 100...SPREADING CATEGORICAL PD EWRD WITH UPR PV SUPPORT. HVY RAIN A THREAT EARLY TO MID MORNING THRU THE MO RVR CORRIDOR...BUT WITH MAIN CONVECTIVE FRONT PUSHING SWRD AND SPREADING COLD POOL MORE TO S THAN GUIDANCE SUGGESTS INTO LLJ...LKLY WL KEEP THE PERSISTENT NEWER DEVELOPMENT MAINLY TO S OF AREA. CANNOT RULE OUT AN ISOLD MARGINALLY SVR HAILER WANDERING TOWARD LOWER MO RVR CORRIDOR THROUGH MID MORNING AS 7-8C/KM MID LVL LAPSE RATES PUSH INTO THE AREA. WL CERTAINLY HAVE TO KEEP EYE ON ESPLY URBAN KSUX AREA FOR FLOODING THREAT IF WAA CAN DEVELOP MORE STOUTLY HEADING TOWARD DAYBREAK. OTHERWISE...LOOK FOR A LITTLE DROPOFF IN COVERAGE AND EXTENT OF CONVECTION BY AFTN. TEMPS CHALLENGING AS WL BE DEALING WITH STUBBORN RAIN COOLED AIRMASS FOR MUCH OF THE DAY...AND EXPECT WL LIMIT RECOVERY BY QUITE A BIT. ALREADY IN LOWER 70S TOWARD I80... SO NOT TOO FAR TO GO TO REACH EXPECTED KSUX HIGH ARND 80. HARD TO GAIN A LOT OF CONFIDENCE IN WHERE LOW LVL BNDRY WL END UP PUSHING INTO SUCH STRONG SLY FLOW. BREEZY TO WINDY CONDITIONS EXPECTED AS LLJ AND POST MCS GRADIENT ALLOWS WINDS TO SFC LATER THIS MORNING/AFTN. NEXT CHALLENGE IS THE SVR THREAT TDA. WITH SOME INDICATION OF MID LVL RIDGING BETWEEN SYSTEMS...LKLY THAT ACTIVITY WL BE SOMEWHAT SLOW TO DEVELOP TDA...ESPLY CONSIDERING LKLY LIMIT TO SFC BASED DESTABILIZATION IN AND NEAR AREA. SHUD EFFECTIVELY CAP MOST AREAS TO DEVELOPMENT UNTIL WAVE CAN APPROACH THE AREA FROM THE SOUTHWEST BY LATER INTO THE EVENING...AND GET START OF LLJ INCREASE AND REFOCUS TO THE W. ELEVATED CAPE INCREASES TO 1500-2000 J/KG OVER MUCH OF THE AREA TONIGHT. WITH DEEP LYR SHEAR ON ORDER OF 35-45 KTS...EXPECT ORGANIZATION OF SYSTEM BEST THREAT FOR SVR WX LKLY STARTS AS MORE ISOLD HAIL THREAT IN THE SCNTRL/MID JAMES VALLEY AREAS BY EARLY TO MID EVENING...THEN SPREADS EWRD FROM LATE EVENING INTO THE EARLY OVERNIGHT HOURS WITH LLJ FOCUS. WL LKLY SEE A TRANSITION TOWARD MORE OF A WIND THREAT...BUT ELEVATED INSTABILITY INDICATES THAT HAIL...AND PERHAPS A WIND DRIVEN HAIL THREAT WL EXIST NEAR ANY ORGANIZED VORTEX ALG LEADING DEVELOPMENT LINE. PROBABLY A LARGER AND MORE DEFINITE CONCERN IS FOR HVY RAINFALL...WITH NEAR OR BETTER THAN 1.75 INCH PWAT...AND HPC HAS PLACED A SLIGHT RISK OF EXCESSIVE RAINFALL OVER ABOUT THE NERN 2/3 OF CWA THRU TONIGHT. WITH SOMEWHAT A LACK OF CONFIDENCE IN WHERE HEAVIEST RAIN MAY SET UP...HELD OFF ON ISSUING A FLASH FLOOD WATCH AT THIS TIME...BUT DID MENTION SOME HVY RAIN FAVORING THE NWRN AREAS. ALL THE CONVECTION SHUD START TO GIVE SFC BNDRY A DECENT KICK BY LATER TONIGHT. SVRL SLNS...CONSISTENT WITH INDIVIDUAL JET STRUCTURES...WOULD SUGGEST THAT WHILE SFC BNDRY MAY CONTINUE SWRD EVENTUALLY REACHING KS/MO AREAS BY SAT...THE 850 HPA BNDRY ATCUALLY TRIES TO STALL VERY NEAR SERN CWA RIGHT INTO SUNDAY. WL BE IN PLACE AS FAIRLY STRONG WAVE PUSHES UP INTO THE AREA FRI NIGHT INTO SAT... REMAINING CONSISTENT WITH EARLIER FCST. THIS SHUD INDUCE ANOTHER PULSE OF CONVECTIVE ACTIVITY...WITH INSTABILITY REMAINING ALFT. DETAILS GET HARDER AND HARDER TO JUSTIFY AS MODELS GET CONVECTIVELY WORKED OVER...AND THUS CHANGES TO FCST ARE LESS AND LESS BY THE WEEKEND. WL HOLD ONTO SAT NIGHT INTO SUNDAY AS QUIET TIME WITH RIDGING ALFT AHEAD OF CLOSED LOW IN SW MOVING TOWARD PLAINS... AND GET SOME PUSH OF MORE STABLE LOW LVL AIR ON SFC RIDGE FM N. AS MUCH AS DIDNT WANT TO...INTRODUCED A SMALL CHC POPS FOR SUN NIGHT INTO MONDAY AS SLNS SHOWING VARIETY OF TROUGHING STRUCTURES PUSHING INTO AREA... WHILE FIGHTING THE LOW LVL DRYING PUSH...DO HAVE ENOUGH SUPPORT FROM COOLING AFLT AND INSTABILITY TO DRIVE SOME SHRA/TRSA THRU THE AREA. /CHAPMAN && .AVIATION... SHRA/TSRA MOVING EAST ACROSS THE AREA THIS MORNING. GREATEST CHANCE OF PROLONGED TSRA AND OCNL MVFR CIGS/VSBYS AT KFSD/KSUX THROUGH 15Z-16Z...WITH BULK OF ANY TSRA ACTIVITY THEN EXPECTED TO MOVE EAST OF TAF LOCATIONS FOR THE BALANCE OF THE AFTERNOON/EARLY EVENING. REDEVELOPMENT LIKELY WEST OF THE MISSOURI RIVER LATE THIS AFTN... MOVING INTO THE JAMES RIVER VALLEY TOWARD SUNSET...THEN CONTINUING EAST ACROSS THE FORECAST AREA THROUGH THE OVERNIGHT HOURS TONIGHT.
