AREA FORECAST DISCUSSION FOR WESTERN SD AND NORTHEASTERN WY NATIONAL WEATHER SERVICE RAPID CITY SD 143 PM MDT THU JUL 1 2010 .DISCUSSION...19Z SURFACE ANALYSIS HAD BOUNDARY FROM NORTH CENTRAL ND INTO SOUTHWEST WY...WITH A WEAK LOW IN CENTRAL WY ALONG BOUNDARY. WEAK CONVECTION DEVELOPING OVER EASTERN WY IN RESPONSE TO WEAK WAVE OVER CENTRAL WY AND CAP EROSION AS WE APPROACH MAX HEATING. EXPECT WAVE TO ASSIST CONVECTION ALONG/NEAR THE BOUNDARY THROUGH THE EVENING HOURS. SHEAR IS SUFFICIENT FOR ROTATING UPDRAFTS...WITH BEST SHEAR ALONG THE PERIPHERY OF THE UPPER LEVEL RIDGE FROM NORTHWEST WY INTO WESTERN ND. MLCAPE IN THE 1.5KJ/KG RANGE. BEST CHANCE FOR SEVERE STORMS THIS AFTERNOON/EVENING WILL BE OVER NORTHEASTERN WY AND FAR NORTHWESTERN SD. FRIDAY...SURFACE BOUNDARY MOVES LITTLE DURING THE DAY AS UPPER LEVEL RIDGE REMAINS ANCHORED OVER THE LOWER MS RIVER VALLEY. GIVEN SOUTHWEST FLOW ALOFT WOULD EXPECT SOME KIND OF WAVE TO WORK NORTHEAST DURING THE DAY...INTERACTING WITH THE SURFACE BOUNDARY AND PEAK HEATING TO PRODUCE TSRA. UPPER LEVEL RIDGE WILL BREAK DOWN AT NIGHT AS UPPER TROUGH PUSHES INTO THE NORTHERN ROCKIES. THIS WILL ALLOW SURFACE BOUNDARY TO SLIDE INTO THE CWA...BECOMING FOCUS FOR CONVECTION. MLCAPE OF 0.5-1KJ/KG AVAILABLE AS DRIER AIR WORKS INTO/MIXES IN OVER THE CWA...WITH ENOUGH SHEAR FOR SUPERCELLS. SATURDAY...BOUNDARY SLOWLY SLIDES SOUTHEAST AS UPPER TROUGH EDGES INTO THE NORTHERN PLAINS. IT WILL AGAIN BE THE FOCUS FOR CONVECTION WITH UP TO 3KJ/KG MLCAPE/25M/S 0-6KM BULK SHEAR AVAILABLE OVER SOUTH CENTRAL SD. EXTENDED...THOUGH MEDIUM RANGE MODELS ARE DIVERGENT ON SOLUTIONS IN THE EXTENDED...IT GENERALLY LOOKS LIKE A ZONAL FLOW PATTERN WILL DEVELOP BY EARLY NEXT WEEK. MAIN CHANCES FOR STORMS SHOULD BE EARLY ON IN THE EXTENDED AS A SERIES OF DISTURBANCES PASS OVER THE AREA SUNDAY AND MONDAY. BETTER CHANCES LOOK TO BE OVER NORTHERN AND WESTERN PORTIONS OF THE CWA. WILL KEEP REST OF THE EXTENDED ON THE DRIER SIDE FOR NOW...WITH JUST THE POTENTIAL FOR ISOLATED STORMS OVER THE BLACK HILLS AREA AND POINTS TO THE NORTH AND EAST DURING THE MIDDLE OF THE WEEK. TEMPERATURES LOOK TO BE NEAR OR SLIGHTLY ABOVE AVERAGE LEVELS. && .AVIATION...ISOLATED THUNDERSTORMS ARE POSSIBLE ACROSS NORTHEAST WYOMING AND FAR WESTERN SOUTH DAKOTA LATE THIS AFTERNOON AND EVENING...RESULTING IN LCL MVFR VSBY AND GUSTY WINDS NEAR ANY STORMS.
