AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BISMARCK ND 910 PM CDT TUE JUL 30 2013 .UPDATE... ISSUED AT 905 PM CDT TUE JUL 30 2013 AT 9 PM CDT...RADAR AND AND VISUAL OBSERVED TOWERING CUMULUS LINE JUST NORTH OF BISMARCK IDENTIFIES THE WEAK FRONTAL BOUNDARY ACROSS CENTRAL NORTH DAKOTA. WINDS SHOULD SIFT TO THE NORTH IN BISMARCK SHORTLY AND EVENTUALLY DICKINSON AS WELL. SO FAR ONLY ISOLATED SHOWERS AND THUNDERSTORMS ALONG THAT LINE. WILL LOWER TO SLIGHT CHANCE THUNDERSTORMS FOR THE REMAINDER OF THE EVENING AND GENERALLY SOUTH OF LAKE SAKAKAWEA. UPDATE ISSUED AT 625 PM CDT TUE JUL 30 2013 NORTHWEST FLOW ALOFT WITH SEVERAL WEAK FEATURES THAT HAVE POTENTIAL FOR PRODUCING THUNDERSTORMS THIS EVENING. WOULD LIKE TO TRIM POPS FOR THE EVENING IN THE AREAS THAT HAVE THE LEAST POTENTIAL FRO THUNDERSTORMS. GENERALLY DROPPED THE POPS FROM LIKELY TO CHANCE ACROSS THE SOUTH CENTRAL WHERE MUCH OF THE PRECIPITATION HAS DRIFTED SOUTH OF THE SOUTH DAKOTA BORDER. FOR NOW FOCUSING ON SCATTERED TO ISOLATED STORMS IN CENTRAL NORTH DAKOTA ALONG A WEAK COLD FRONTAL BOUNDARY MOVING SOUTH...AND A STORM IN WEST CENTRAL NORTH DAKOTA THAT HAS DRIFTED IN FROM MONTANA. WITHIN A FEW HOURS...MAY BE ABLE TO DROP THE CHANCE ALTOGETHER FOR THE AREAS NORTH OF LAKE SAKAKAWEA. && .SHORT TERM...(THIS EVENING THROUGH WEDNESDAY) ISSUED AT 227 PM CDT TUE JUL 30 2013 LATEST WATER VAPOR IMAGERY/RAP UPPER AIR SHOWS TWO DISTINCT SHORTWAVES. ONE NEAR GREAT FALLS IS AHEAD OF THE MAIN UPPER TROUGH SWINGING THROUGH SOUTHERN SASKATCHEWAN AND ALBERTA. THE SECOND WAS SEEN JUST NORTH OF BILLINGS MOVING EAST. VISIBLE IMAGERY SHOWS PARTIAL CLEARING AHEAD OF THE WAVE IN EASTERN MONTANA. LATEST INDICATIONS ARE THE STRONGEST INSTABILITY AND LIFT WILL OCCUR IN SOUTH DAKOTA AND JUST REACH INTO FAR SOUTHERN NORTH DAKOTA THROUGH THIS EVENING. HOWEVER...THE LATEST HIGH RESOLUTION SHORT TERM MODELS SUGGEST THAT AN AREA OF SHOWERS AND THUNDERSTORMS WILL DEVELOP WITH THE GREAT FALLS SHORTWAVE AS IT MOVES INTO WESTERN NORTH DAKOTA THIS AFTERNOON. AN AREA OF THUNDERSTORMS FROM NEAR WATFORD CITY TO BEACH WILL DEVELOP BY 21Z AND SPREAD SOUTHEAST. SPC HAS SKEWED BACK THE SLIGHT RISK OF SEVERE THUNDERSTORMS TO FAR SOUTH CENTRAL NORTH DAKOTA. AS INDICATED BY THE HRRR...A COUPLE OF STRONG TO POSSIBLY SEVERE THUNDERSTORMS COULD BE EMBEDDED WITHIN THE AREA OF SHOWERS AND THUNDERSTORMS FORECAST TO DEVELOP IN THE ABOVE MENTIONED AREA THROUGH EARLY EVENING...IN ADDITION TO FAR SOUTHERN NORTH DAKOTA PER SPC. IT APPEARS THE INFLUENCE OF THE NORTHERN STREAM SHORTWAVE PIVOTING SOUTHEAST FROM SOUTHERN CANADA MAY BE ENOUGH TO MAINTAIN THE SEVERE WEATHER PARAMETERS AND THREAT. WILL CONTINUE TO MONITOR THROUGH THE AFTERNOON. CLOUD COVER AND SCATTERED SHOWERS HAVE CERTAINLY HELPED TO INHIBIT ANY SIGNIFICANT LOW LEVEL INSTABILITY FROM DEVELOPING. PRESSURE FALLS HAVE NOT YET COMMENCED OVER WESTERN AND CENTRAL NORTH DAKOTA AND A DELAY FOR ANYTHING SURFACE BASED WILL LIKELY CONTINUE THROUGH LATE AFTERNOON AND POSSIBLY THROUGH THE EVENING. THE LATEST SPC MESOANALYSIS SHOWS LOW/MID LEVEL LAPSE RATES VERY WEAK ACROSS WESTERN/CENTRAL NORTH DAKOTA...WITH THE BEST THREAT FOR SUPERCELL DEVELOPMENT IN NORTHERN SOUTH DAKOTA. THE CANADIAN UPPER TROUGH SWINGS THROUGH LATE TONIGHT INTO EARLY WEDNESDAY MORNING AS DRIER AND MORE STABLE AIR ARRIVE. NO PRECIPITATION EXPECTED FOR WEDNESDAY. .LONG TERM...(WEDNESDAY NIGHT THROUGH TUESDAY) ISSUED AT 227 PM CDT TUE JUL 30 2013 CONTINUED BELOW NORMAL TEMPERATURES WILL HIGHLIGHT THE EXTENDED FORECAST. THE 12 UTC GUIDANCE SUITE IS IN GOOD AGREEMENT ON A NORTHWEST UPPER LEVEL FLOW PATTERN REMAINING IN PLACE ACROSS THE NORTHERN PLAINS THROUGHOUT THE EXTENDED FORECAST. THIS SUPPORTS THE CONTINUATION OF BELOW NORMAL TEMPERATURES THROUGH THE PERIOD...WITH FORECAST HIGHS GENERALLY IN THE 70S. NORTHWEST FLOW IS NOTORIOUS FOR LOW PREDICTABILITY WAVES YIELDING THE POTENTIAL FOR ISOLATED CONVECTION NEARLY ANY DAY. HOWEVER...THE BEST CHANCES FOR WIDESPREAD PRECIPITATION LOOK TO BE SATURDAY THROUGH SUNDAY NIGHT AS THE PACIFIC NORTHWEST UPPER LOW PROPAGATES ALONG THE CREST OF THE RIDGE INTO THE NORTHERN PLAINS. LOOKING BEYOND THE CURRENT EXTENDED FORECAST PERIOD...THE 12 UTC GFS/ECMWF CONTINUE THE TREND OF TRANSPORTING ARCTIC ENERGY SOUTH POSSIBLY INTO THE NORTHERN PORTIONS OF THE CONUS IN THE AUGUST 8-9 TIME FRAME. WHILE IT IS STILL A WAYS OUT...THE ANOMALOUSLY DEEP UPPER LEVEL LOW COULD RESULT IN A PERIOD OF SIGNIFICANTLY BELOW NORMAL TEMPERATURES. WILL CONTINUE TO MONITOR OVER THE COMING DAYS. && .AVIATION...(FOR THE 00Z TAFS THROUGH 00Z WEDNESDAY EVENING) ISSUED AT 905 PM CDT TUE JUL 30 2013 AT 9 PM CDT...A WEAK COLD FRONTAL BOUNDARY WAS SLIDING SOUTH ACROSS CENTRAL NORTH DAKOTA. ISOLATED SHOWERS AND THUNDERSTORMS WERE ASSOCIATED WITH THIS FEATURE AND SHOULD DIMINISH AFTER SUNSET. VFR AT ALL TAF SITES. && .BIS WATCHES/WARNINGS/ADVISORIES... NONE. && UPDATE...WAA SHORT TERM...KS LONG TERM...AYD AVIATION...WAA
