AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SIOUX FALLS SD 1043 PM CDT MON JUN 24 2013 .UPDATE... ISSUED AT 1003 PM CDT MON JUN 24 2013 EVENING RAOBS REALLY WARM ALOFT TO THE SOUTHWEST...WITH COOLER READINGS TO THE NORTHEAST REFLECTED IN THE EARLIER LINGERING SHOWERS AND THUNDERSTORMS OVER THE FAR EASTERN CWA. LOOKS MUCH AS IF A GOOD PORTION OF THE LATER EVENING WILL BE QUIET...AS ACTIVITY OUT WEST STRUGGLES A BIT PUSHING INTO THE WARM/DRY LAYER ALOFT TO THE EAST. LIKELY TO SEE DEVELOPMENT OF A WARM ADVECTION WING ONCE AGAIN WHICH SHOULD FAVOR THE EASTERN HALF OF THE CWA AS IT EVOLVES WITH STRENGTHENING LOW LEVEL JET TONIGHT AS WESTERN PLAINS WAVE PUSHES EASTWARD. VERY LIKELY THAT THERE COULD END UP AN AREA BETWEEN THE DWINDLING WESTERN ACTION AND THAT LIFTING/DEVELOPING NORTHEAST...AS SEVERAL OF THE LATER AFTERNOON HRRR RUNS HAVE SUGGESTED. HOWEVER...LAST TWO RUNS OF 00Z AND 01Z HAVE BEEN COMPLETE OPPOSITES WITH ONE EXTREMELY ACTIVE OVER A LARGE AREA... AND ANOTHER WITH VERY LITTLE ACTIVITY. MADE A FEW CHANGES TO DECREASE POPS IN PART OF THE AREA BETWEEN WESTERN AND EASTERN AREAS OF PRECIP...AND DID INCREASE POPS SOMEWHAT EARLY TUESDAY IN THE FAR SOUTHEAST AS WILL BE LAST AREA OF LINGERING WAVE. OTHER INTERESTING NOTE...A WEAK CONVECTIVE HEAT BURST THIS EVENING AT PHILIP...AND IF WE COULD GET A LITTLE BETTER ORGANIZED ACTIVITY MOVING INTO THE AREA...THEN DISSIPATE...WOULD CERTAINLY BE A SET UP FAVORABLE TO GET SUCH AN EVENT IN OUR CWA GIVEN THE UPSTREAM THERMODYNAMIC PROFILE FOR KLBF. && .SHORT TERM...(THIS EVENING THROUGH TUESDAY) ISSUED AT 414 PM CDT MON JUN 24 2013 THE VANISHING OF NIGHTTIME AND EARLY MORNING SHOWERS AND STORMS HAS TAKEN PLACE PRETTY MUCH AS EXPECTED...ALTHOUGH WILL KEEP AN EYE ON THE POTENTIAL FOR ISOLATED SHOWERS OR STORMS EAST OF I 29 LATE THIS AFTERNOON. THE SLOW START TO CLEARING AND HEATING PRETTY MUCH GUARANTEES A SLOW START TO STORMS THIS EVENING. THE GFS...NAM... AND GEM ALL SHOW A SHORT WAVE PASSING OVER THE AREA TONIGHT... CURRENTLY NOTED ENTERING INTO THE WESTERN PLAINS. THE FOCUS HAS SHIFTED TO AN EXPECTATION OF OVERNIGHT ACTIVITY STILL LINGERING AT DAYBREAK...INSTEAD OF EVENING SHOWERS AND STORMS DECREASING STEADILY AFTER MIDNIGHT AS WE HAD IN THE MORNING FORECAST. PATH AND TIMING WILL DEPEND ON WHERE AND HOW EXTENSIVELY STORMS DEVELOP WEST OF OUR AREA EARLY THIS EVENING. MUCH OF THE GUIDANCE SUGGESTS A TRACK MORE TO THE NORTH...BUT WITH A SLIGHT RISK OF SEVERE STORMS EXTENDING DOWN THROUGH THE MISSOURI RIVER VALLEY. THIS WOULD AT LEAST REFLECT A HIGHER CONDITIONAL SEVERE RISK SOUTH AND THIS SEEMS REASONABLE. POPS WILL BE FAIRLY GENERAL OVER THE AREA TONIGHT WITH THE HIGHEST POPS MIGRATING SLOWLY FROM WEST TO EAST. REFINEMENT WILL BE MADE AS ACTIVITY DEVELOPS AND THE PATH OF STORMS BECOMES EVIDENT. HIGHEST QPF POTENTIAL LOOKS TO BE IN OUR NORTHERN AND EASTERN ZONES AS THE PRECIPITATION RIDES OVER A BIT OF CAPPING POTENTIAL. FOR THE TIME BEING WILL GO WITH THE GUIDANCE IDEA OF MODEST AMOUNTS...THAT IS LESS THAN AN INCH...BUT THIS OF COURSE WILL LIKELY TO TURN OUT WITH DRASTIC SHORT RANGE VARIATIONS EVEN IF THE GENERAL RAINFALL OUTLOOK IS GOOD. LOW TEMPERATURES LOOK TO BE NEAR GUIDANCE VALUES WHICH IS VERY SLIGHTLY COOLER THAN WHAT WE HAVE BEEN GOING FOR...MAINLY MID TO UPPER 60S. LINGERING SHOWERS AND STORMS SHOULD DECREASE EARLY TUESDAY MORNING AND WARMING SHOULD HELP KEEP STORMS AWAY FOR MOST OF TUESDAY. HOWEVER SOME CHANCE WILL BE RESTORED MAINLY NORTH BY EARLY AFTERNOON AS BOUNDARIES PROVIDED BY NIGHTTIME STORMS MAY LINGER FOR A FOCUS...AND LATE DAY STORMS MAY DEVELOP MAINLY NORTHEAST FOR THE SAME REASON. FURTHER SOUTH...IT WILL BE HARD TO GET ANYTHING GOING MOST OF THE DAY DUE TO THE WARMING AND CAPPING. HOWEVER...THERE WILL BE A DISTINCT WAVE APPROACHING WHICH COULD TURN THAT AROUND...AGAIN THOUGH NOT UNTIL FAIRLY LATE IN THE DAY. TEMPERATURES SHOULD BE A LITTLE WARMER THAN TODAY THOUGH ANY 90 PLUS HIGHS SHOULD BE CONFINED TO SOUTH OF INTERSTATE 90. .LONG TERM...(TUESDAY NIGHT THROUGH MONDAY) ISSUED AT 414 PM CDT MON JUN 24 2013 ALL MODELS ARE IN GOOD AGREEMENT IN BRINGING THE AFOREMENTIONED AND FAIRLY VIGOROUS SHORT WAVE THROUGH OUR NORTHERN AND SOME OF OUR EASTERN ZONES MAINLY TUESDAY EVENING. HAVE A HIGH DEGREE OF CONFIDENCE THAT SOME RAINFALL WILL OCCUR...JUST LIKELY NOT EVERYWHERE THROUGHOUT OUR NORTH AND EAST...THEREFORE PLACED COVERAGE POPS IN THOSE AREAS TUESDAY NIGHT INSTEAD OF UNCERTAINTY. THE HIGHEST ML CAPES EXIST TO THE WEST OF THE PRECIP AREAS. BUT STILL...ML CAPES OF OVER 1000 J/KG ARE NOTED IN OUR NORTH AND EAST COUPLED WITH 0 TO 3KM BULK SHEAR OF 25 TO 35 KNOTS EARLY IN THE EVENING. WITH 700MB TEMPERATURES CLOSE TO ONLY AROUND +10C...BELIEVE A LOW END SEVERE THREAT EXISTS IN OUR NORTH AND EAST EARLY IN THE EVENING...WITH HAIL AROUND THE SIZE OF QUARTERS OR HALF DOLLARS AND WIND GUSTS AROUND 60 MPH. THIS ACTIVITY SHOULD RAPIDLY MOVE EASTWARD THOUGH. OTHERWISE AFTER TUESDAY NIGHT...OUR WELL ADVERTISED UPPER RIDGING BEGINS TO TAKE HOLD WHICH WILL BEGIN TO QUIET DOWN OUR WEATHER. A COLD FRONT...MAINLY IN NAME ONLY...WILL SHIFT OUR WINDS TO THE NORTHWEST LATE TUESDAY NIGHT AND LASTING THROUGH THE DAY ON WEDNESDAY. WITH MIXING POTENTIAL AND NOT ANY BONAFIDE COOL AIR BEHIND THE WAVE...DO NOT EXPECT A LOT OF COOLING ON WEDNESDAY WITH WIDESPREAD 80S STILL PREVAILING. DEW POINTS WILL BE DOWN THOUGH AT LEAST WEST OF I 29. WITH LIGHT WINDS AND RELATIVELY DRIER AIR OOZING DOWN THROUGH THE AREA WEDNESDAY NIGHT...WE CAN EXPECT LOWS DOWN INTO THE LOWER 60S FOR MOST LOCATIONS. ON THURSDAY AS THE UPPER RIDGE BEGINS TO NUDGE WESTWARD...THERE IS SOME MODEL AGREEMENT IN BRINGING A WAVE DOWN OUR AREA FROM NORTHWEST TO SOUTHEAST WHICH COULD SPAWN SOME ACCAS SHOWERS OR THUNDERSTORMS. THE WAVE IS BASED AT 700MB...AND THE SOUNDINGS AND HUMIDITY TIME SECTIONS DO SHOW A PRETTY GOOD INCREASE IN MID LEVEL MOISTURE. THE 12Z NAM BLANKETS JUST ABOUT OUR ENTIRE FORECAST AREA WITH LIGHT PRECIPITATION. HOWEVER I CHOSE TO KEEP THE SMALL POPS IN OUR MISSOURI RIVER VALLEY ZONES WHERE THE STRONGEST PORTION OF THE 700MB DEFORMATION TAKES PLACE PROVIDING MID LEVEL CONVERGENCE... AND THIS IS JUXTAPOSED WITH A 700MB THERMAL GRADIENT GOING FROM +9C TO +12C IN THAT AREA. THURSDAYS HIGHS WILL STILL BE KIND OF WARM...WITH MID 80S TO AROUND 90 COMMON. THEN THINGS BEGIN TO CHANGE. BOTH THE ECMWF AND GFS ARE IN EXCELLENT AGREEMENT IN CONTINUING TO PUSH THE UPPER RIDGE WESTWARD...WHILE DEEPENING AN UPPER LOW OVER THE EASTERN UNITED STATES.. THIS CREATES A HIGH AMPLITUDE PATTERN WITH THE LATEST MODEL RUNS SHOWING A LOT OF SHORT WAVE ENERGY MOVING SOUTHWARD DOWN THE MISSISSIPPI VALLEY REGION. COOL HIGH PRESSURE BEGINS TO FILL IN DOWN FROM THE NORTHWEST AND THUS REALLY COOLS OFF OUR 850MB TEMPERATURES IN A BIG WAY. BY SUNDAY...THE ECMWF HAS +10C TO +14C AT 850MB IN OUR FORECAST AREA...WITH THE GFS EVEN COOLER. THEREFORE A COOLING TREND IS IN ORDER. FURTHERMORE...WITH THE SHORT WAVE ENERGY INTERACTING WITH COOL MID LEVEL TEMPERATURES... WOULD NOT RULE OUT SOME INSTABILITY SHOWERS IN OUR EASTERN ZONES THIS WEEKEND. THE POPS ON DAY 7 MONDAY ARE WISHY WASHY AND WERE MAINLY BASED ON A MORE SIGNIFICANT SHORT WAVE DIVING DOWN THE NORTHWEST FLOW ALOFT ON SOME PREVIOUS VERSION OF THE ECMWF. THE NEW 12Z ECMWF HAS BACKED OFF ON THIS IDEA WITH THE LARGE UPPER TROUGH CONTINUING JUST TO OUR EAST. && .AVIATION...(FOR THE 06Z TAFS THROUGH 06Z TUESDAY NIGHT) ISSUED AT 1035 PM CDT MON JUN 24 2013 CONVECTIVE CHANCES RATHER DIFFICULT TO PIN DOWN THIS EVENING...WITH NEW MODEL RUN INCONSISTENCIES...BUT THE BETTER CHANCES LOOK TO BE ACROSS NORTHWESTERN IOWA INTO SOUTHWESTERN MINNESOTA LATER TONIGHT INTO TUESDAY MORNING. AFTER MORNING CONVECTION EXITS THE AREA...WILL SEE A BREAK BEFORE POSSIBLE REDEVELOPMENT NORTH OF INTERSTATE 90 LATER ON TUESDAY AFTERNOON. WHILE VFR CONDITIONS ARE EXPECTED TO DOMINATE THROUGH THE TAF PERIOD...BRIEF REDUCED CONDITIONS WILL BE POSSIBLE IN AREAS EFFECTED BY SCATTERED CONVECTION. && .FSD WATCHES/WARNINGS/ADVISORIES...
