AREA FORECAST DISCUSSION FOR SOUTHEAST SD/SOUTHWEST MN/NORTHWEST IA NATIONAL WEATHER SERVICE SIOUX FALLS SD 216 AM CDT SUN MAY 30 2004 .DISCUSSION... LARGE STRATIFORM PRECIPITATION REGION CONTINUING TO WEAKEN AND DECREASE IN COVERAGE EARLY THIS MORNING. SURFACE COLD FRONT STILL WEST OF KMHE AT 07Z...WITH A BAND OF THUNDERSTORMS DEVELOPING ALONG IT FROM ABOUT KHON TO GREGORY COUNTY. EXPECT THESE TO WEAKEN AS THEY MOVE EAST INTO WORKED OVER AIR. DRY SLOT FROM NEBRASKA RAPIDLY WORKING NORTH...AND SOUTHEAST CWA MAY SEE VERY LITTLE PRECIPITATION THIS MORNING. EXPECT TO SEE SOME LINGERING SHOWERS/THUNDER THIS MORNING AS SHORTWAVE ENERGY ROTATES EAST. WILL THEN SET UP FOR SOME ADDITIONAL SHOWERS AND ISOLATED THUNDERSTORMS THIS AFTERNOON AND EVENING AS COLD POOL ALOFT SETTLES IN. NICE 500MB COLD ADVECTION ALONG WITH A SUBSTANTIAL AMOUNT OF 300-500MB QS AND QN FORCING. ALSO SOME DECENT 850-700MB MOISTURE CONVERGENCE. SO...WILL BE INCREASING AFTERNOON POPS INTO THE LIKELY CATEGORY. WHILE QPF AMOUNTS SHOULD REMAIN BELOW A QUARTER OF AN INCH...DO EXPECT THERE TO BE OFF AND ON SHOWERS FOR MANY LOCATIONS. THIS SHOULD LINGER INTO THE EVENING OVER THE NORTHEAST HALF OR SO OF THE CWA...BEFORE FORCING LIFTS NORTHEAST. BY MONDAY...COLD POOL IN PLACE WITH A LITTLE HEATING POSSIBLE OVER SOUTHERN HALF OF CWA...WHICH WILL LIKELY JUST AID IN THE REDEVELOPMENT OF AFTERNOON AND EVENING SHOWERS/THUNDER. WILL HAVE TO WATCH AS WEAK UPPER LEVEL WAVE DROPS SOUTHEAST FROM NORTH DAKOTA AND BUFKIT SOUNDINGS ALSO SUGGEST SOME 50 TO 200 J/KG CAPE VALUES. MAY BE ENOUGH TO CREATE SOME SMALL HAIL ACROSS NORTHEAST CWA. AREA REMAINS IN WRAP AROUND NORTHWEST FLOW INTO TUESDAY...AND ANOTHER WEAK WAVE PASSES ACROSS THE AREA...WHICH WILL REQUIRE POPS AGAIN. WARMER AIR FINALLY STARTS TO TRY TO WORK BACK NORTH ON THURSDAY...SO WILL KEEP THINGS BELOW NORMAL UNTIL THEN. ALSO OF CONCERN THE NEXT COUPLE OF DAYS WILL BE WIND. FAIRLY DEEP AND FAST NORTHWEST FLOW SHOULD SET UP A WINDY SUNDAY AND MONDAY WITH BREEZY CONDITIONS CONTINUING INTO TUESDAY. MAY SEE SOME GUSTS TO NEAR 40 MPH BOTH SUNDAY AND MONDAY. RAPID...SHORT TERM FLOODING CONDITIONS SHOULD BE OVER WITH FOR NOW...BUT WILL LIKELY BE DEALING WITH RIVER FLOODING FOR THE NEXT COUPLE OF DAYS. && .FSD...WATCHES/WARNINGS/ADVISORIES... SD...NONE.
