AREA FORECAST DISCUSSION FOR WESTERN SD AND NORTHEASTERN WY NATIONAL WEATHER SERVICE RAPID CITY SD 105 PM MDT SUN AUG 17 2014 .SHORT TERM...THIS EVENING THROUGH MONDAY NIGHT ISSUED AT 105 PM MDT SUN AUG 17 2014 THE MAIN FEATURE ON THE LARGE SCALE MAPS THIS AFTERNOON IS THE SLOW MOVING CLOSED LOW MOVING EASTWARD THROUGH THE SOUTHERN CANADIAN PRAIRIE PROVINCES. IMPULSES ROTATING AROUND THE SOUTHERN PERIPHERY OF THIS SYSTEM OVER A PERSISTENT WEAK SURFACE TROUGH ARE THE WEATHER MAKERS FOR THE UNR CWFA TODAY. THE FIRST ONE PRODUCED A FEW MODERATELY STRONG STORMS OVER NORTHWESTERN SOUTH DAKOTA EARLY THIS MORNING WHICH MOVED INTO CENTRAL SOUTH DAKOTA. A STRONG SUBTROPICAL UPPER RIDGE ACROSS THE SOUTHWESTERN TWO THIRDS OF THE CONUS IS KEEPING THE MONSOON PLUME PUSHED OFF TO THE SOUTHEAST LIMITING MOISTURE ADVECTION INTO THE NORTHERN PLAINS. THIS AFTERNOON AND TONIGHT...THE NEXT IMPULSE...CURRENTLY MOVING INTO/THROUGH NORTHEAST WYOMING AND WESTERN SOUTH DAKOTA DURING THE EARLY AFTERNOON HOURS IS A LITTLE STRONGER AND WILL PROVIDE MORE SHEAR TO THE ENVIRONMENT. BULK SHEAR IS GENERALLY FORECAST TO REMAIN BELOW 40 KTS MUCAPE BELOW 2000 J/KG SBCAPE BELOW 1500 J/KG. HOWEVER SEVERAL SEVERE STORMS ARE POSSIBLE WITH THE PRIMARY THREATS BEING LARGE HAIL AND LOCAL GUSTY THUNDERSTORM WINDS. DEVELOPMENT OF THIS SECOND GROUP OF STORMS IS EXPECTED THROUGH THE EARLY TO MID AFTERNOON HOURS. SOME EARLY DEVELOPMENT IS OCCURRING OVER THE BLKHLS AND ALONG THE OUTFLOW BOUNDARY SOUTHEAST OF THE HILLS. THE CELLS ARE EXPECTED TO COMBINE INTO AN MCS OVER THE WESTERN SOUTH DAKOTA PLAINS AND THEN MOVE INTO CENTRAL SOUTH DAKOTA BETWEEN 01Z AND 03Z. GOOD STORM MOTION SHOULD PRECLUDE THE THREAT OF WIDESPREAD HEAVY RAINFALL ACCUMULATIONS. THE ENVIRONMENT MIGHT ALSO SUPPORT A FEW COLD AIR FUNNELS AS OCCURRED IN NORTHEASTERN SOUTH DAKOTA YESTERDAY. BEHIND THE SHORT WAVE CLOUD COVER WILL DECREASE RAPIDLY LEAVING GENERALLY CLEAR SKIES BY 06Z. MONDAY AND MONDAY NIGHT....A DRY NORTHWEST FLOW WILL KEEP CONDITIONS FAIR AND DRY. BREEZY NORTHWEST WINDS ARE EXPECTED TO DEVELOP OVER THE PLAINS BY MIDDAY MONDAY. THE MAXIMUM TEMPERATURES MONDAY WILL BE A FEW DEGREES COOLER THAN TODAY AND MINIMUM TEMPERATURES MONDAY NIGHT A FEW DEGEES COOLER THAN TONIGHT. && .LONG TERM...TUESDAY THROUGH SUNDAY ISSUED AT 105 PM MDT SUN AUG 17 2014 AN UPPER RIDGE OVER THE AREA ON TUESDAY WILL PUSH OFF TO THE EAST ON WEDNESDAY AS A LARGE UPPER TROUGH DEEPENS OVER THE WRN CONUS. THIS WILL RESULT IN ACTIVE SOUTHWESTERLY FLOW ALOFT OVER THE FORECAST AREA. SHORTWAVES EMBEDDED IN THE FLOW WILL BRING A NEARLY DAILY CHANCE OF THUNDERSTORMS TO THE REGION FROM TUESDAY AFTERNOON INTO THE WEEKEND. MID-LONG RANGE MODEL SOLUTIONS CONTINUE TO SUGGEST THE UPPER TROUGH WILL MOVE EASTWARD OVER THE NORTHERN PLAINS SOMETIME NEXT WEEKEND BUT THE MODELS DIFFER ON THE TIMING. TEMPS WILL REMAIN NEAR AVERAGE THROUGH THE WEEK...BUT ARE EXPECTED TO COOL SLIGHTLY OVER THE WEEKEND. && .AVIATION...FOR THE 18Z TAFS THROUGH 18Z MONDAY ISSUED AT 105 PM MDT SUN AUG 17 2014 SCATTERED THUNDERSTORMS...SOME PRODUCING LARGE HAIL AND LOCALLY STRONG WIND GUSTS WILL BE LCOATED OVER WESTERN SOUTH DAKOTA DURING THE REST OF THE AFTERNOON. THE THUNDERSTORMS WILL MOVE EASTWARD DURING THE AFTN/EARLY EVE...AND COMPLETELY OUT OF THE FORECAST AREA AROUND 03Z. AN AREA OF MVFR CIGS MAY DEVELOP OVER PARTS OF SOUTHWESTERN AND SOUTH CENTRAL SOUTH DAKOTA AFT 06Z...CONTINUING UNTIL AROUND 12Z. OTHERWISE...VFR CONDITIONS WILL PREVAIL. && .UNR WATCHES/WARNINGS/ADVISORIES... SD...NONE. WY...NONE. && SHORT TERM...CARPENTER LONG TERM...10 AVIATION...10
