AREA FORECAST DISCUSSION FOR WESTERN SD AND NORTHEASTERN WY NATIONAL WEATHER SERVICE RAPID CITY SD 549 PM MDT TUE AUG 5 2014 .SHORT TERM...THIS EVENING THROUGH WEDNESDAY NIGHT ISSUED AT 250 PM MDT TUE AUG 5 2014 CURRENT SURFACE ANALYSIS SHOWS LOW PRESSURE OVER SOUTHWESTERN NEB...WITH FRONTAL BOUNDARY JUST TO THE SOUTH AND WEST OF THE FORECAST AREA. UPPER LEVEL ANALYSIS SHOWS WEAKENING RIDGE OVER THE PLAINS WITH SOUTHWEST FLOW OVER THE ROCKIES INTO THE HIGH PLAINS. REGIONAL RADARS SHOW SCATTERED SHOWERS AND THUNDERSTORMS HAVE DEVELOPED EARLY THIS AFTERNOON ACROSS EASTERN WY AND THE BLACK HILLS. STORMS ARE MOVING AT A REASONABLE SPEED RIGHT NOW...BUT SOME OF THE ACTIVITY OVER THE NORTHERN BLACK HILLS IS REGENERATING OVER THE SAME AREAS. TEMPS AT 20Z ARE IN THE UPPER 60S AND 70S ACROSS THE AREA WITH EAST TO SOUTHEAST WINDS. UNSETTLED WEATHER WILL CONTINUE INTO TONIGHT AS WEAK UPPER LEVEL ENERGY PASSES THROUGH THE REGION WITH ABUNDANT MOISTURE IN PLACE OVER THE AREA. THE THREAT FOR ANY STRONG TO POSSIBLY SEVERE STORMS SHOULD MOSTLY BE LIMITED TO SOUTHWESTERN SD LATE THIS AFTERNOON AND EVENING. HAIL WOULD BE THE PRIMARY THREAT FROM ANY SEVERE STORMS. THE MAIN CONCERN FROM STORMS WILL BE LOCALLY HEAVY RAINFALL AS PRECIPITABLE WATERS REMAIN NEAR OR ABOVE 150 PERCENT OF NORMAL ACROSS A GOOD PORTION OF THE CWA...WITH THE HIGHEST VALUES TO THE NORTH AND EAST OF THE BLACK HILLS. ACTIVITY SHOULD TAPER OFF IN INTENSITY AND COVERAGE OVERNIGHT. CHANCES FOR SHOWERS AND THUNDERSTORMS WILL CONTINUE ON WEDNESDAY... ESPECIALLY DURING THE AFTERNOON AND EVENING HOURS...AS UNSETTLED SOUTHWEST FLOW REMAINS. STORMS ARE EXPECTED TO BE LESS NUMEROUS AND NOT AS INTENSE AS DRIER AIR BUILDS IN AND PRECIPITABLE WATER VALUES GRADUALLY LOWER FROM WEST TO EAST. TEMPERATURES WILL REMAIN ON THE COOL SIDE...WITH HIGHS IN THE 70S AND LOWER 80S. ACTIVITY WILL LINGER INTO WEDNESDAY NIGHT...GENERALLY TAPERING OFF AGAIN FROM WEST TO EAST OVERNIGHT. && .LONG TERM...THURSDAY THROUGH TUESDAY ISSUED AT 250 PM MDT TUE AUG 5 2014 ACTIVE SOUTHWEST FLOW WILL CONTINUE THROUGH THE WEEKEND BRINGING A DAILY CHANCE FOR SHOWERS AND THUNDERSTORMS. MOST OF THE ACTIVITY WILL HAVE A STRONG DIURNAL COMPONENT...SUPPORTING THE HIGHEST CHANCES FOR PRECIP IN THE AFTERNOON/EVENING PERIODS... ESPECIALLY OVER THE BLACK HILLS GIVEN OROGRAPHIC INFLUENCES. TEMPERATURES WILL WARM THROUGH THE WEEK WITH HEIGHT RISES AND THERMAL RIDGING. BY THE WEEKEND...THE MODELS BEGIN TO DIVERGE ON THE PATTERN THAT WILL SET UP FOR NEXT WEEK. THE ECMWF AND A FEW OF THE GFS ENSEMBLE MEMBERS REFORM THE WESTERN CONUS RIDGE PUTTING THE AREA IN A DRIER WEST/NORTHWEST FLOW PATTERN BY THE END OF THE WEEKEND. HOWEVER THE 12Z RUN OF THE OPERATIONAL GFS AND A FEW OF THE OTHER GFS ENSEMBLE MEMBERS ONLY REBUILD A WEAK RIDGE FOR THE WEEKEND WITH A TRANSITION TO WEST/SOUTHWEST FLOW AGAIN BY EARLY NEXT WEEK. WITH THESE DIFFERENCE JUST WENT WITH THE ALLBLEND/BCALLBLEND SOLUTION UNTIL BETTER AGREEMENT CAN BE REACHED. && .AVIATION...(FOR THE 00Z TAFS THROUGH 00Z WEDNESDAY EVENING) ISSUED AT 546 PM MDT TUE AUG 5 2014 SHOWERS AND THUNDERSTORMS WILL CONTINUE ACROSS THE HIGHER TERRAIN OF THE BLACK HILLS AND NORTHEASTERN WYOMING THROUGH LATE THIS EVENING. THESE STORMS ARE EXPECTED TO DECREASE IN INTENSITY DURING THE NEXT SEVERAL HOURS....BUT SHOWERS WITH EMBEDDED THUNDER WILL CONTINUE ACROSS A WIDESPREAD AREA FOR MOST OF THE OVERNIGHT HOURS. MVFR CIGS AND IFR VSBY ARE POSSIBLE IN THE STRONGER STORMS. AFTER 04Z...MOIST UPSLOPE FLOW ACROSS WESTERN SOUTH DAKOTA WILL ALLOW FOR STRATUS WITH MVFR/IFR CIGS TO DEVELOP TONIGHT OVER THE EASTERN AND NORTHEASTERN SLOPE. IFR CIGS...WITH LCL LIFR CONDITIONS...WILL BE POSSIBLE IN VICINITY OF BLACK HILLS. && .UNR WATCHES/WARNINGS/ADVISORIES... SD...NONE. WY...NONE. && SHORT TERM...26 LONG TERM...MLS AVIATION...CARPENTER
