NWS Sioux Falls, SD wrote its last area forecast discussion before the first event at Jun 5, 3:31 PM CST, 59 minutes earlier.
AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA NATIONAL WEATHER SERVICE SIOUX FALLS SD 431 PM CDT SUN JUN 5 2005 .DISCUSSION... AN ACTIVE PATTERN WILL CONTINUE THROUGH THE WEEK. IN ADDITION...THE WARMEST WEATHER OF THE YEAR WILL OCCUR EARLY THIS WEEK. VORT MAX MOVING ACROSS THE CWA THIS AFTERNOON WILL EXIT THIS EVENING. SHOWERS AND THUNDERSTORMS EAST OF THE JAMES RIVER WILL RAPIDLY DISSIPATE WITH THE LOSS OF THE HEATING LATER THIS EVENING. THEN EXPECT THAT SKIES WILL RAPIDLY CLEAR OVER THE REGION AS HIGH PRESSURE SLIDES ACROSS THE AREA. WINDS SHOULD RAPIDLY DROP OFF OVERNIGHT AND WILL ONLY BEGIN TO INCRASE IN SOUTH CENTRAL SOUTH DAKOTA LATE. WITH ALL OF THE RAIN ACORR THE VERMILLION...JAMES AND BIG SIOUX VALLEY THE LAST THREE DAYS...EXPECT THAT THERE WILL BE AT LEAST PATCHY VALLEY FOG. ONLY THE FACT THAT THERE WILL BE SOME WIND ABOVE THE SURFACE AND PREVENT A STRONG INVERSION FROM FORMING WILL PREVENT WIDESPREAD DENSE FOG. ON MONDAY...RIDGE MOVES TO THE EAST AND VERY WARM AIR MOVES NORTH. EXPECT THAT ANY FOG WILL RAPIDLY DISSIPATE AS IT SHOULD BE SHALLOW AND THERE WILL STILL BE RELATIVELY DRY AIR ALOFT. A WARM FRONT WILL THEN RAPIDLY MOVE NORTH OF INTERSTATE 90. SOUTH OF THE FRONT...VERY WARM AIR WILL MOVE IN WITH MANY LOCALES REACHING THE LOWER 90S. IT WILL ALSO BECOME INCREASINGLY HUMID DURING THE DAY AS MOISTURE RAPIDLY MOEVS NORTH. ON MONDAY NIGHT...THE FRONT WILL STALL FROM NORTH CENTRAL SOUTH DAKOTA INTO SOUTHWEST MINNESOTA. A LOW LEVEL JET WILL DEVELOP LATE BRINGING VERY MOIST AIR NORTH. SOUTH OF THE SURFACE FRONT 700 MB TEMPS WILL BE 10 TO 12C WHICH SHOULD EFFECTIVELY CAP THE ATMOSPHERE. HOWEVER ACROSS NRN SD AND SW MN...CAP IS WEAKER IN ADDITION...AN UPPER WAVE WILL MOVE FROM WRN SD INTO CENTRAL ND. EXPECT THIS TO INTERACT WITH THE 850 MB FRONT AND INITIATE CONVECTION AFTER MIDNIGHT IN SOUTHWEST MINNESOTA. WITH LAPSE RATES OVER 7 C/KM...ELEVATED CAPES ARE OVER 1000 J/KG AND SHEAR IS MORE THAN ADEQUATE FOR A FEW ELEVATED SUPERCELLS TO DEVELOP AND PRODUCE LARGE HAIL. THE STORMS SHOULD WEAKEN DURING THE MORNING AS THE WAVE MOVES INTO CANADA AND LOW LEVEL JET WEAKENS. HOWEVER THE CLOUDS AND RAIN AS WELL AS CYCLOGENESIS IN THE WRN NEBRASKA WILL EFFECTIVELY KEEP THE WARM FRONT LOCKED IN PLACE IN THE FAR NRN CWA OR EVEN FORCE IT SOUTH TOWARD INTERSTATE 90. EXPECT THE ATMOSPHERE TO REMAIN CAPPED MOST OF THE DAY. THEN NAM AND GFS SHOWS A VERY STRONG WAVE MOVING INTO CENTRAL NEBRASKA DURING THE LATE AFTERNOON AND EVENING. EXPECT THIS WILL PROVIDE ENUF MIDLEVEL LIFT TO BEGIN TO WEAKEN THE CAP FROM ABOVE AS HEATING AND MOISTURE ERODE CAP FROM BELOW. THEREFORE THINKING BETWEEN 21Z AND 00Z...THERE WILL BE RAPID DEVELOP OF CONVECTION ALONG THE SURFACE BOUNADRY IN THE JAMES VALLEY. THIS WILL RAPIDLY SPREAD EAST ALONG THE FRONT NORTH OF I90. AT THIS TIME...THE PROPAGATION IS EXPECTED TO BE EAST OR ESE SO KEPT HIGHEST POPS NORTH OF I90. SHOULD CONVECTION DEVELOP...CAPES OF 2500 J/KG...0-1 KM SHEAR APPROACHING 20 KTS AND 0-6 SHEAR OF 60 KTS WOULD RESULT IN SUPERCELL DEVELOPMENT AND THE THREAT OF VERY LARGE HAIL AND EVEN TORNADOES NORTH OF I90. PERSONS WITH PLANS FOR TUESDAY EVENING NEED TO KEEP ABREAST OF FUTURE FORECASTS. DID CONTINUE TO FOLLOW THE NAM THROUGH WED MORN AND THEN SIDED WITH THE ECMWF FOR WED THROUGH SUNDAY. THIS IS BECAUSE THE ECMWF IS MAINTAINS A TROUGH IN THE WEST AND RIDGE EAST WHICH IS A VERY STABLE PATTERN. THEREFORE EXPECT THAT THE WAVE MIDWEEK WILL MOVE NORTHEAST TOWARD MANITOBA AS A NEW WAVE DROPS INTO THE SW US. THEREFORE...FOR WED EXPECT THAT THE COLD FRONT WILL BE MUCH SLOWER THAN EITHER GFS OR NAM. THIS BRING A CHANCE OF TSRA INTO THE ERN HALF OF THE CWA WED AFTERNOON AND EVENING. IT WILL ALSO BE FAIRLY WARM WITH TEMPS IN THE 80S SOUTH OF THE FRONT. EVEN THURSDAY THE FRONT MAY BE CLOSE ENUF TO PRODUCE A CHANCE OF THUNDERSTORMS IN NW IA. FRIDAY LOOKS TO BE A BREAK AND THEN ANOTHER WAVE MOVES TOWARD THE CWA ON SATURDAY. THIS WILL BRING A CHANCE OF TSRA IN THE SOUTH FRIDAY NIGHT WITH THE RETURN FLOW AND THEN SATURDAY NORTH OF THE WARM FRONT. TEMPS WILL REMAIN NEAR NORMAL FROM THU-SUN. && .AVIATION...
