Area forecast discussion, Aug 30, 4:15 PM MST, 3 hours 50 minutes before
AREA FORECAST DISCUSSION FOR WESTERN SD AND NORTHEASTERN WY NATIONAL WEATHER SERVICE RAPID CITY SD 515 PM MDT SAT AUG 30 2014 .SHORT TERM...THIS EVENING THROUGH SUNDAY NIGHT ISSUED AT 312 PM MDT SAT AUG 30 2014 CURRENT SURFACE ANALYSIS SHOWS LOW PRESSURE OVER FAR NORTHEAST WY...WITH COLD FRONT FROM FAR EASTERN MT INTO CENTRAL WY. UPPER LEVEL ANALYSIS SHOWS WEAK RIDGING OVER THE DAKOTAS WITH BROAD TROF COVERING MUCH OF THE WESTERN CONUS. NUMEROUS SHORTWAVES ARE NOTED WITHIN THE TROF...WITH THEM CURRENTLY OVER NORTHEAST MT...CENTRAL WY AND SOUTH CENTRAL MT...AND EASTERN OR AND SOUTHWESTERN ID. SKIES ARE VARIABLY CLOUDY OVER NORTHEAST WY...WITH MOSTLY SUNNY SKIES TO THE EAST. ISOLATED SHOWERS AND STORMS HAVE STARTED TO DEVELOP OVER NORTHEAST WY IN THE VICINITY OF THE COLD FRONT. TEMPS RANGE FROM THE UPPER 70S TO UPPER 80S ACROSS THE AREA. WINDS ARE SOUTH-SOUTHEAST...BREEZY AT TIMES OVER MOST OF THE AREA...EXCEPT FOR NORTHWESTERLY WINDS OVER CAMPBELL CO BEHIND THE FRONT. CHANCES FOR SHOWERS AND STORMS WILL INCREASE THROUGH THE LATE AFTERNOON AND EVENING FROM WEST TO EAST...ESPECIALLY ACROSS NORTHERN PORTIONS OF THE CWA...AS THE SHORTWAVE OVER WY MOVES EAST-NORTHEAST THROUGH THE REGION. THE STRONGEST FORCING WITH THE WAVE MOVES ACROSS NORTHERN PORTIONS OF THE CWA AND POINTS FURTHER TO THE NORTH THIS EVENING. THIS IS WHERE THE BEST CHANCES FOR PCPN WILL BE...AS WELL AS THE RISK FOR ISOLATED SEVERE STORMS. CHANCES FOR PCPN AND SEVERE WEATHER WILL DECREASE FURTHER SOUTH ACROSS THE CWA...WITH ONLY SLIGHT CHANCES FOR A SHOWER OR STORM OVER FAR SOUTHERN SD THROUGH THE EVENING. THINKING FROM PREVIOUS FORECAST GENERALLY HOLDS...WITH THE BEST THREAT FOR STRONG TO SEVERE STORMS GENERALLY NEAR OR NORTH OF A LINE FROM GILLETTE TO NEAR SPEARFISH...TO FAITH AND DUPREE. HOWEVER...THE SLIGHTLY LATER TIMING OF THIS WAVE ADDS SOME UNCERTAINTY TO THE RISK...ESPECIALLY OVER EASTERN PORTIONS OF THE RISK AREA LATER ON. INSTABILITY IS FAIRLY STRONG ACROSS THE AREA...ESPECIALLY TO THE NORTH AND EAST OF THE BLACK HILLS LATE THIS AFTERNOON INTO THE EVENING. SHEAR WILL ALSO BE STRONGEST TO THE NORTH AND EAST OF THE SURFACE LOW AS IT SLOWLY TRACKS FROM NORTHEAST WY THROUGH WESTERN SD THIS EVENING. THE MAIN THREATS FROM ANY SEVERE STORMS WILL BE LARGE HAIL AND STRONG WIND GUSTS...BUT AN ISOLATED TORNADO CANNOT BE TOTALLY RULED OUT OVER EXTREME NORTHEAST WY INTO NORTHWEST SD. LOCALLY HEAVY RAINFALL IS ALSO POSSIBLE...ESPECIALLY ACROSS FAR NORTHWESTERN SD. MOST OF THE ACTIVITY WITH THIS WAVE WILL EXIT EAST OF THE CWA AROUND 06Z...WITH LINGERING ISOLATED LIGHTER ACTIVITY POSSIBLE INTO THE OVERNIGHT OVER THE CWA. GUSTY NORTHWEST WINDS WILL DEVELOP ACROSS THE WESTERN SD PLAINS DURING THE EVENING...AFTER THE FRONT PASSES. THE STRONGEST WINDS WILL GENERALLY BE IN THE RAPID CITY AREA...AS WELL AS THE NEARBY PLAINS TO THE NORTH AND EAST. WINDS WILL GRADUALLY DECREASE AFTER MIDNIGHT. THE NEXT SHORTWAVE OVER OR/ID WILL APPROACH OUR WESTERN ZONES BY EARLY SUNDAY MORNING...WITH THIS ONE TRACKING A BIT FURTHER SOUTH ACROSS THE CWA DURING THE DAY. THIS SYSTEM SHOULD BRING A MORE WIDESPREAD COVERAGE OF PCPN ACROSS THE AREA...WITH COLDER AIR ALOFT KEEPING THE ATMOSPHERE UNSTABLE. SHOWERS ARE LIKELY ACROSS THE BLACK HILLS AREA...WITH A PRETTY GOOD CHANCE FOR SHOWERS ACROSS THE REST OF THE CWA DURING THE DAY...ESPECIALLY IN THE LATE MORNING AND AFTERNOON. A FEW THUNDERSTORMS ARE POSSIBLE...BUT CLOUD COVER AND COOLER AIR WILL HELP TO KEEP CAPE VALUES RATHER LOW. HIGHS WILL ONLY BE IN THE 70S ACROSS THE SD PLAINS...WITH 60S OVER THE BLACK HILLS AND NORTHEAST WY. SHOWERS WILL EXIT EASTERN AREAS IN THE EVENING WITH A COOL NIGHT ON TAP FOR MOST AREAS. YET ANOTHER DISTURBANCE IS PROGGED TO APPROACH WESTERN PORTIONS OF THE AREA LATE SUNDAY NIGHT OR MONDAY MORNING. && .LONG TERM...MONDAY THROUGH SATURDAY ISSUED AT 312 PM MDT SAT AUG 30 2014 SHORTWAVE EMBEDDED IN CYCLONIC FLOW WILL BRING CONTINUED CHANCES FOR -SHRA/-TSRA MONDAY...BUT COVERAGE SHOULD BE LOWER THAN SUNDAY ON THE PLAINS. UPPER TROUGH WILL SHARPEN OVER THE PACIFIC NORTHWEST TUESDAY/WEDNESDAY BRINGING A FLAT UPPER RIDGE/THERMAL RIDGE OVER THE CWA RESULTING IN DRIER/WARMER WEATHER. LONG TERM GUIDANCE NOW SHOWING WEST/NORTHWEST FLOW ALOFT AND A SERIES OF FRONTS DANCING ACROSS THE REGION FOR THURSDAY THROUGH SATURDAY. RESULT WILL BE CHANCES FOR -SHRA/-TSRA ALONG WITH COOLER TEMPERATURES FOR THE END OF NEXT WEEK. && .AVIATION...FOR THE 00Z TAFS THROUGH 00Z SUNDAY EVENING ISSUED AT 514 PM MDT SAT AUG 30 2014 SCATTERED TSRA WILL MOVE ACROSS WY INTO WESTERN SD THROUGH THIS EVENING. IFR VSBYS ARE EXPECTED WITH THE STRONGEST STORMS ALONG WITH LARGE HAIL AND GUSTY WINDS. OUTSIDE OF STORMS...VFR CONDITIONS ARE EXPECTED TONIGHT. ADDITIONAL SHRA/-TSRA WILL DEVELOP EARLY SUNDAY AND PERSIST MUCH OF THE DAY WITH AREAS OF MVFR CIGS/VSBYS. && .UNR WATCHES/WARNINGS/ADVISORIES... SD...NONE.
