AREA FORECAST DISCUSSION FOR WESTERN SD AND NORTHEASTERN WY NATIONAL WEATHER SERVICE RAPID CITY SD 522 PM MDT SAT AUG 10 2013 .SHORT TERM...THIS EVENING THROUGH SUNDAY NIGHT ISSUED AT 119 PM MDT SAT AUG 10 2013 CURRENT SURFACE ANALYSIS PLACES HIGH OVER THE MIDWEST WITH LOW OVER THE CENTRAL ROCKIES WHILE FRONTAL BOUNDARY CONTINUES TO STRETCH ALONG THE NEBRASKA/SOUTH DAKOTA BORDER. UPPER LEVEL ANALYSIS PLACES LOW SPINNING ALONG THE NRN CALIFORNIA/SRN OREGON COAST WHILE NEGATIVELY TILTED RIDGE STRETCHES FROM THE SRN PLAINS UP INTO THE NRN ROCKIES. SERIES OF SHORT WAVES CONTINUE TO LIFT THROUGH THE RIDGE. FOR THE REST OF THIS AFTERNOON INTO THIS EVENING...NEXT WAVE PUSHING THROUGH CENTRAL WYOMING CONTINUES IT SLOW APPROACH TOWARDS THE AREA WHICH WILL RESULT IN SOME STORMS DEVELOPING. THIS WAVE APPEARS TO BE MORE SUBTLE THAN LAST NIGHTS...SO EXPECT STORMS TO BE MORE ISOLD/SCT. THERE IS A SEVERE CONCERN...THOUGH...AS ~30-40 KTS 0-6KM BULK SHEAR WILL IN PLACE COMBINED WITH CAPE VALUES ~1-2 KJ/KG. THEREFORE WILL HAVE TO KEEP AN EYE ON ANY STORMS THAT DO DEVELOP. ALSO...IF AFOREMENTIONED SFC BOUNDARY CREEPS A BIT MORE NORTH MAY HAVE TO KEEP AN EYE OF STORMS THAT MOVE ALONG IT FOR A BRIEF TORNADIC THREAT...THOUGH THIS DOES REMAIN QUITE LOW. MOST STORMS SHOULD DISSIPATE BY LATE TONIGHT BUT HAVE KEEP SOME LOW POPS IN LATE AS HIGH RES MODELS HAVE BEEN CONSISTENT WITH THE POSSIBILITY OF A FEW STORMS LOITERING AROUND. GIVEN THE PERSISTENT PATTERN OF LATE NIGHT CONVECTION HAVE A HARD TIME RULING THIS OUT. WITH THE AMPLE LOW LEVEL MOISTURE IN PLACE COMBINED WITH THE LIGHT EASTERLY FLOW...EXPECT SOME PATCHY FOG MAY DEVELOP LATE ALONG THE EASTERN FLANKS OF THE BLACK HILLS INTO THE PLAINS A BIT. ON SUNDAY...AFOREMENTIONED FOG SHOULD DISSIPATE EARLY. OTHERWISE...QUIET CONDITIONS ARE EXPECTED UNTIL AFTERNOON WHEN THE NEXT IN OUR LITTLE PARADE OF SHORT WAVES SLIDE THROUGH THE PERSISTENT PATTERN. AGAIN...SEVERE THREAT REMAINS WITH INCREASING INSTABILITY THOUGH SHEAR WILL BE MODEST. MAIN CONCERN MAY BE NEAR SFC BOUNDARY TOWARDS THE NEBRASKA BORDER. && .LONG TERM...MONDAY THROUGH SATURDAY ISSUED AT 119 PM MDT SAT AUG 10 2013 MEAN WESTERN NOAM RIDING TO REMAIN IN THE PERIOD...WITH DOWNSTREAM NEGATIVE HEIGHT ANOMALIES LINGERING IN EASTERN NOAM. NE PAC TROUGHING WILL SUPPORT NUMEROUS SUBTLE IMPULSES IN THE FLOW...WITH A MORE SUBSTANTIAL WAVE POSSIBLE TOWARD THE END OF NEXT WEEK...SUPPORTING AN EASTERN BIAS TO THE WESTERN CONUS RIDGE. MEANWHILE A NORTHERN STREAM UPPER TROUGH WILL GRAZE THE REGION MONDAY...SUPPORTING A PSEUDO BACKDOOR FRONT INTO THE AREA...STALLING OVER THE WESTERN HALF OF THE AREA...AND PROVIDING A PATHWAY FOR PERTURBED WNW FLOW THROUGH MID WEEK. MEAN ENSEMBLES AS WELL AS THE ECMWF ARE SUPPORTING A REMOVAL OF THE HIGH LATITUDE BLOCKING RIDGE WITH MORE PROGRESSIVE TENDENCIES TO THE FLOW OVER WESTERN CANADA TOWARD THE END OF THE WEEK. HOWEVER...ECMWF AND GFS DETERMINISTIC RUNS SUPPORT ANOTHER ROUND OF STAUNCH WESTERN NOAM RIDGING MUCH MORE PRONOUNCED THAN THE CURRENT WESTERN NOAM RIDGE...WITH NEGATIVE HEIGHT TENDENCIES OVER SE CANADA ONCE AGAIN. IF LL MOISTURE REMAINS AS IN THE ECMWF PROGS...AN ACTIVE PATTERN COULD CERTAINLY RETURN TO THE REGION...ESP IF DOWNSTREAM BLOCKING DEVELOPS ONCE AGAIN. RETAINED LOW PRECIP CHANCES THROUGH THUR...CONTINUED WITH A DRY FRIDAY AND SAT GIVEN FLOW RE-ADJUSTMENT AND UPPER RIDGING/WARMING.
