AREA FORECAST DISCUSSION FOR WESTERN SD AND NORTHEASTERN WY NATIONAL WEATHER SERVICE RAPID CITY SD 158 PM MDT SAT JUL 13 2013 .SHORT TERM...THIS EVENING THROUGH SUNDAY NIGHT ISSUED AT 157 PM MDT SAT JUL 13 2013 LATEST SURFACE ANALYSIS HAS A BROAD AREA OF LOW PRESSURE ACROSS SOUTHEASTERN MONTANA AND NORTHEASTERN WYOMING WITH ANOTHER AREA OF LOW PRESSURE OVER EAST CENTRAL SOUTH DAKOTA FROM THE DECAYING FRONTAL BOUNDARY THAT PUSHED THROUGH THE CWA ON FRIDAY. RADAR IMAGERY IS SHOWING SOME CONVECTION OVER THE NORTHERN BLACK HILLS AND ACROSS SOUTH CENTRAL SOUTH DAKOTA, WATER VAPOR IMAGERY DEPICTS A COUPLE OF SHORTWAVES PUSHING THROUGH CENTRAL WYOMING. FOR THE REST OF THE AFTERNOON...CONVECTION WILL CONTINUE TO DEVELOP AND INCREASE ACROSS THE CWA. DIABATIC SURFACE HEATING HAS IGNITED A FEW STORMS ALREADY OVER THE BLACK HILLS. 35 KT WESTERLY 500 MB FLOW COMBINED WITH 15-20 KTS SOUTHERLY SURFACE FLOW COULD YIELD SOME SUPER-CELLULAR DISCRETE STORMS. THE SHORTWAVES FROM WYOMING WILL MOVE THROUGH CWA THIS EVENING UNDER RIGHT ENTRANCE REGION OF 70 KT JET IN PLACE ALONG THE US/CANADIAN BORDER. ACTIVITY WILL INCREASE THIS EVENING AS THE WEAK COOL FRONT DROPS OUT OF MONTANA INTO WESTERN PORTIONS OF CWA. LOCALLY HEAVY RAIN IS POSSIBLE GIVEN PWAT/S FROM 100-150 PERCENT OF NORMAL. HOWEVER STORM MOTION APPEARS TO BE AROUND 20KTS...SO NO NEED TO HIGHLIGHT ANY FLOODING CONCERNS. THE STRONGER STORMS MAY EVOLVE INTO SMALL LINES OR CLUSTERS THIS EVENING...BUT SHOULD NOT PERSIST TOO LATE TONIGHT GIVEN THE MODEST LOW LEVEL JET. ON SUNDAY...THE FRONTAL BOUNDARY WILL STALL ACROSS THE CWA. LOW LEVEL MOISTURE AND SURFACE DEWPOINTS IN THE 60S TO LOW 70S WILL PROVIDE AMPLE MOISTURE AS THE 850-300MB STEERING FLOW BECOMES LESS THAN 10KTS. MODEL PWAT/S RISE TO 150-175 PERCENT OF NORMAL WITH WELL-DEFINED MONSOONAL MOISTURE PATTERN IN PLACE. SOUTHWEST FLOW ALOFT WILL KEEP ACTIVE PATTERN GOING WITH CONVECTION LIKELY DEVELOPING EARLY...AND THUS HAVE KEEP PREVIOUS POPS/QPF AND LOCALLY HEAVY RAIN MENTION IN THE GRIDS AND HWO. && .LONG TERM...MONDAY THROUGH SATURDAY ISSUED AT 157 PM MDT SAT JUL 13 2013 MONSOONAL FLOW PATTERN WILL REMAIN OVER THE REGION ON MONDAY...BRINGING A CHANCE FOR THUNDERSTORMS. THERE LOOKS TO BE A MINIMAL THREAT FOR STRONG TO SEVERE STORMS...ESPECIALLY ACROSS NORTHERN AND WESTERN PORTIONS OF THE CWA...ALONG WITH LOCALLY HEAVY RAIN. A DRIER PATTERN WILL DEVELOP FOR THE MIDDLE PORTION OF THE WEEK AS AN UPPER LEVEL RIDGE BUILDS FURTHER NORTH ACROSS THE ROCKIES AND PLAINS AND SHIFTS THE MONSOONAL MOISTURE PLUME TO THE NORTH AND WEST OF THE AREA. CHANCES FOR THUNDERSTORMS WILL LIKELY RETURN BY THE END OF THE WEEK AS THE RIDGE SLIDES FURTHER WESTWARD TOWARD THE WEST COAST STATES...ALLOWING WEAK DISTURBANCES TO PASS OVER THE RIDGE AND ACROSS THE NORTHERN PLAINS. TEMPERATURES WILL BE NEAR TO SLIGHTLY ABOVE AVERAGE THROUGH THE REST OF THE WEEK. && .AVIATION...FOR THE 18Z TAFS THROUGH 18Z SUNDAY AFTERNOON ISSUED AT 157 PM MDT SAT JUL 13 2013 SCATTERED SHOWERS AND THUNDERSTORMS WILL DEVELOP THIS AFTERNOON AND PERSIST INTO TONIGHT AS MONSOONAL MOISTURE REMAINS OVER THE REGION AND A WEAK COLD FRONT MOVES INTO THE AREA. THE BETTER CHANCES WILL BE FROM THE BLACK HILLS AREA...EASTWARD INTO CENTRAL SD. A FEW STORMS COULD BE SEVERE ACROSS THIS AREA DURING THE AFTERNOON AND EVENING WITH HAIL AND GUSTY WINDS. BRIEF MVFR CONDITIONS ARE POSSIBLE IN THE VICINITY OF ANY STRONGER STORMS THAT DEVELOP. && .HYDROLOGY...SUNDAY AND SUNDAY EVENING ISSUED AT 157 PM MDT SAT JUL 13 2013 CONTEMPLATED THE NEED FOR A FLASH FLOOD WATCH ON SUNDAY/SUNDAY EVENING WITH PWAT/S OF 150-175 PERCENT OF NORMAL/OVER +2 STANDARD DEVIATIONS COMBINED WITH THE SLOW STORM MOVEMENT. HOWEVER MODEL DIFFERENCES ON WHERE THE FRONTAL BOUNDARY WILL STALL AND WHERE THE CONVECTION WILL LIKELY DEVELOP WILL NEED TO BE BETTER REFINED BEFORE THE AREAL THREAT CAN BE PINPOINTED. THUS WILL LEAVE THE DECISION TO LATER SHIFTS. && .UNR WATCHES/WARNINGS/ADVISORIES... SD...NONE. WY...NONE. && SHORT TERM...MLS LONG TERM...15 AVIATION...15 HYDROLOGY...MLS
