Area forecast discussion, Jun 2, 4:35 PM MST, 2 hours 55 minutes before
AREA FORECAST DISCUSSION FOR WESTERN SD AND NORTHEASTERN WY NATIONAL WEATHER SERVICE RAPID CITY SD 535 PM MDT SAT JUN 2 2012 .DISCUSSION...WATER VAPOR IMAGERY SHOWS UPPER RIDGING ACROSS THE NORTHERN PLAINS WITH THE NEXT TROUGH APPROACHING THE PACIFIC NORTHWEST. A SERIES OF STRONG WAVES ARE CROSSING THE NORTHERN ROCKIES PUSHING INTO THE NORTHERN PLAINS. SATELLITE/REGIONAL MOSAIC SHOWS SHOWERS AND STORMS DEVELOPING ACROSS WYOMING AND MONTANA AND MOVING EASTWARD. SURFACE ANALYSIS SHOWS CORRESPONDING LOW PRESSURE WEST OF THE CWA ALONG WITH A THERMAL RIDGE WHERE CONVECTIVE ACTIVITY IS ONGOING. THESE WAVES WILL CONTINUE EASTWARD BRINGING THUNDERSTORMS TO THE AREA MAINLY THIS EVENING. STORMS ARE EXPECTED TO DEVELOP INTO AN MCS AND PUSH INTO NORTHEAST WYOMING BY 00Z TONIGHT...THEN CONTINUE EASTWARD INTO WESTERN SOUTH DAKOTA. OVERALL IT LOOKS LIKE INSTABILITY WILL BE GREATLY WEAKENING WITH DIURNAL COOLING...BUT PORTIONS OF NORTHEAST WYOMING AND PERHAPS FAR WESTERN SOUTH DAKOTA MAY STILL SEE MLCAPE VALUES OF 500-1000 J/KG BEFORE SUNSET. GIVEN THIS...THE THREAT FOR HAIL WILL QUICKLY DECREASE AS STORMS ROLL IN...BUT DAMAGING WINDS WILL BE POSSIBLE THROUGH THE EVENING. THE STORMS WILL QUICKLY PUSH INTO CENTRAL SOUTH DAKOTA BY MIDNIGHT...EXITING THE CWA SHORTLY THEREAFTER. WEAK UPPER RIDGING WILL BUILD INTO THE AREA BEHIND THE STORMS EARLY SUNDAY MORNING. A COOL FRONT WILL PUSH INTO THE CWA THROUGH THE MORNING WITH GUSTY NORTHWEST WINDS BEHIND THE FRONT. WINDS AT THIS TIME ARE EXPECTED TO REACH NEAR ADVISORY CRITERIA...HOWEVER HIGH PRESSURE QUICKLY BUILDS IN BEHIND SO GUSTY NORTHWEST WINDS ARE NOT EXPECTED TO LAST LONGER THAN COUPLE HOURS OR SO. OTHERWISE A QUIET DAY EXPECTED SUNDAY WITH HIGHS IN THE UPPER 70S TO UPPER 80S. UPPER RIDGING WILL CONTINUE TO STRENGTHEN HEADING INTO MONDAY AS HIGH PRESSURE DOMINATES THE REGION. SOUTHERLY RETURN FLOW WILL SET UP ACROSS NORTHEAST WYOMING AND FAR WESTERN SOUTH DAKOTA BRINGING IN WARMER AND MORE MOIST AIR. MOST AREAS WILL SEE HIGHS IN THE MID TO UPPER 90S. MODELS ARE SHOWING MLCAPE OF 2000-3000 J/KG FROM NORTHEAST WYOMING TO THE BLACK HILLS AREA AND SOUTHWEST SOUTH DAKOTA...BUT THE BIG QUESTION WILL BE IF THE CAPE CAN BE BROKEN. WILL KEEP IN SLIGHT CHANCE POPS FOR MONDAY AFTERNOON AND EVENING...SINCE THE THINKING RIGHT NOW IS ISOLATED STORMS DEVELOPING ACROSS THE BLACK HILLS AND BIG HORNS...AND ROLLING INTO THE ADJACENT PLAINS. EXTENDED...GFS/ECMWF/ENSEMBLES/RMOP ALL SHOW A BLOCKING RIDGE WILL MOVE LITTLE OVER THE PLAINS STATES NEXT WEEK...PLACING MOST OF THE CWA IN SOUTHWEST FLOW ALOFT. THIS PATTERN WILL BRING SUMMERLIKE TEMPERATURES AND A DAILY CHANCE OF ACTIVE TSRA. && .AVIATION...00Z TAF FORECAST A FAST MOVING DISTURBANCE WILL CREATE A LINE OF SHOWERS AND THUNDERSTORMS WHICH WILL MOVE FROM NORTHEASTERN WYOMING INTO WESTERN SOUTH DAKOTA THIS EVENING. VFR CONDITIONS WILL PREVAIL EXCEPT IN/NEAR TSRA WHEN MVFR CONDITIONS ARE POSSIBLE. A COLD FRONT WILL TRAIL THE DISTURBANCE...BRINGING GUSTY NORTHWEST WINDS TO THE SD PLAINS LATE TONIGHT AND SUNDAY. && .UNR WATCHES/WARNINGS/ADVISORIES... SD...NONE. WY...NONE. &&
