AREA FORECAST DISCUSSION FOR WESTERN SD AND NORTHEASTERN WY NATIONAL WEATHER SERVICE RAPID CITY SD 830 PM MDT SUN AUG 4 2013 .UPDATE... ISSUED AT 821 PM MDT SUN AUG 4 2013 MAIN CHANGE TO THE FORECAST WAS TO SIG LOWER AND ADJUST POPS. MID LEVEL IMPULSE TRAVERSING ND WILL SHIFT EAST OF THE AREA OVERNIGHT. TAIL END OF HEIGHT FALLS MAY SUPPORT AN ISOLD TS ACROSS MAINLY FAR EASTERN AREAS OVERNIGHT...BEING SUPPORTED BY A DEVELOPING NOCTURNAL LLJ. OTHERWISE...LINGERING HIGH TERRAIN CONVECTION SW OF THE FA MAY HOLD TOGETHER AND ADVECT ACROSS THE FAR SOUTHERN FA IF CONVECTION CAN CONNECT WITH POS THETA-E ADVECTION ASSOCIATED WITH THE LLJ. HAVE REMOVED POPS OVER MOST OF NE WY AND AND OPTED FOR A 20 POP MENTION FOR THE EASTERN HALF OF THE FA. SEVERE THREAT SEEMS AWFULLY LIMITED WITH ANY CONVECTION...GIVEN NOCTURNAL BL STABILIZATION. HOWEVER...IF ANY CONVECTION CAN ROOT LOW ENOUGH INTO THE BL...ISOLD SEVERE TS WOULD BE POSSIBLE. CERTAINLY NOT WORTH A MENTION AT THIS POINT. && .SHORT TERM...THIS EVENING THROUGH MONDAY NIGHT ISSUED AT 305 PM MDT SUN AUG 4 2013 CURRENT SURFACE ANALYSIS HAS WEAK LOW PRESSURE OVER THE BLACK HILLS AREA...WITH THE FRONTAL BOUNDARY NOW ORIENTED NORTH-SOUTH FROM FAR EASTERN MT INTO EASTERN CO. UPPER LEVEL ANALYSIS HAS HIGH PRESSURE OVER THE SOUTHERN PLAINS...WITH WEAKENING TROF OVER SOUTH CENTRAL CANADA. NEAR ZONAL FLOW IS IN PLACE OVER THE NORTHERN AND CENTRAL PLAINS WITH LITTLE IN THE WAY OF SHORTWAVE ENERGY NOTED ON WATER VAPOR IMAGERY. SKIES HAVE BECOME MOSTLY SUNNY ACROSS MUCH OF THE AREA. SHOWERS AND STORMS ARE STARTING TO DEVELOP ALONG THE HIGHER TERRAIN OF WY...WITH SOME TOWERING CU NOW OVER THE BLACK HILLS. TEMPS ARE IN THE UPPER 70S AND 80S ACROSS THE AREA WITH SOUTHERLY WINDS ACROSS THE SD PLAINS AND LIGHT AND VARIABLE WINDS FURTHER WEST. FRONTAL BOUNDARY WILL CONTINUE TO MOVE SLOWLY EAST ACROSS WESTERN SD THIS AFTERNOON AND EVENING AND WILL LIKELY BE THE FOCUS FOR SOME THUNDERSTORM DEVELOPMENT...MAINLY DURING THE EVENING HOURS. ANY STORMS THAT DEVELOP OVER THE HIGHER TERRAIN WILL MOVE ONTO THE PLAINS LATE THIS AFTERNOON AND EVENING. LOW LEVEL MOISTURE WILL REMAIN POOLED OVER MUCH OF THE CWA...WITH HIGH CAPE VALUES. WITH THE BOUNDARY OVER THE AREA...SHEAR WILL BE A BIT WEAKER THAN PREVIOUS DAYS...AT LEAST AT LOW LEVELS...BUT STRONG WESTERLY FLOW ALOFT WILL PERSIST. THIS SHOULD STILL BE SUFFICIENT FOR ISOLATED SUPERCELLS TO DEVELOP. THERE IS A SLIOHT RISK FOR SEVERE STORMS OVER MUCH OF NORTHEASTERN WY AND WESTERN SD FOR LATE THIS AFTERNOON AND EVENING. LARGE HAIL AND STRONG WIND GUSTS WILL BE THE MAIN THREATS FROM ANY SEVERE STORMS. ACTIVITY SHOULD GRADUALLY DIMINISH FROM NORTHWEST TO SOUTHEAST ACROSS MOST OF THE AREA OVERNIGHT ISOLATED SHOWERS COULD PERSIST ACROSS FAR SOUTHERN SD INTO MONDAY MORNING. OTHERWISE...MAINLY DRY WX IS EXPECTED INTO MONDAY AFTERNOON. TEMPERATURES WILL BE SIMILAR TO TODAY...WITH HIGHS IN THE 80S ACROSS THE PLAINS...SOME 70S OVER THE BLACK HILLS. SIMILAR WX SETUP IS PROGGED FOR MONDAY...WITH LATE AFTERNOON AND EVENING THUNDERSTORMS POSSIBLE AS WEAK SHORTWAVE ENERGY CROSSES AND MOISTURE REMAINS OVER THE REGION. THE SEVERE STORM THREAT WILL ESSENTIALLY BE OVER THE SAME AREAS. && .LONG TERM...TUESDAY THROUGH SUNDAY ISSUED AT 305 PM MDT SUN AUG 4 2013 A RATHER STRONG COLD FRONT WILL MOVE THROUGH THE NRN PLAINS ON TUESDAY...BRINGING GUSTY NW WINDS AND COOLER AIR INTO THE REGION. BEST CHANCES FOR STORMS ON TUESDAY WILL BE EARLY...WITH DRIER AND MORE STABLE AIR MOVING IN BEHIND THE FRONT. RELATIVELY COOL TEMPS WILL THEN CONTINUE THROUGH THE WEEK...ABOUT 5 DEGREES BELOW CLIMO...WITH LOW CHANCES FOR TSTMS RETURNING BY THE END OF THE WEEK. THE GFS/ECMWF CONTINUE TO SHOW A PRETTY STRONG TROF PUSHING INLAND THE WEST COAST NEXT WEEKEND WHICH WILL AMPLIFY THE RIDGE OVER THE ROCKIES. THIS SHOULD LEAD TO WARMER TEMPS FOR NEXT WEEKEND. && .AVIATION...(FOR THE 00Z TAFS THROUGH 00Z MONDAY EVENING) ISSUED AT 821 PM MDT SUN AUG 4 2013 ISOLATED THUNDERSTORMS WILL BE POSSIBLE OVERNIGHT...MAINLY ACROSS SD.
