NWS Bismarck, ND wrote its last area forecast discussion before the first event at Aug 4, 3:00 PM CST, 25 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BISMARCK ND 400 PM CDT WED AUG 4 2004 .SHORT TERM... LONG WAVE RIDGE WILL KEEP THE WEATHER DRY ACROSS WESTERN AND CENTRAL NORTH DAKOTA OVERNIGHT AND THURSDAY MORNING. CURRENT LIGHT PRECIP BAND OVER CENTRAL ND WILL CONTINUE TO DISSIPATE THROUGH THE EVENING HOURS. BY THURSDAY EVENING THE RIDGE FLATTENS SOMEWHAT AND SHORTWAVE ENERGY BEGINS TRAVERSING THE REGION. IN THE LOWER LAYERS A STRONG LOW LEVEL JET DEVELOPS WITH MOISTURE AND WARM AIR ADVECTION. WITH NORTH DAKOTA LYING AT THE NOSE OF THE JET WE EXPECT SOME NOCTURNAL AND EARLY MORNING THUNDERSTORM ACTIVITY THURSDAY NIGHT AND FRIDAY MORNING. AFTER A BREAK IN THE ACTION FRIDAY NIGHT...AN ADVANCING COLD FRONT WILL BRING ANOTHER ROUND OF THUNDERSTORMS SATURDAY AND SATURDAY NIGHT AS A SMALL BUT VIGOROUS MID LEVEL CLOSED LOW RAPIDLY DIVES SOUTHEAST OUT OF WESTERN CANADA. .LONG TERM... THE CLOSED LOW THAT BEGINS IMPACTING THE REGION DURING THE SHORT TERM WILL CONTINUE ITS EASTWARD TREK DURING THE EXTENDED FORECAST PERIOD. THE 00Z AND 12Z GFS BOTH CONCUR THAT THIS FEATURE WILL COME TO LIGHT...AND THE ECMWF IS ON MUCH THE SAME PAGE...WITH ITS SOLUTION ONLY SLIGHTLY SLOWER AND FURTHER NORTH THAN THE GFS. WITH THIS IN MIND...WE FEEL SOME SHOWERS MAY OCCUR IN THE DEEP LAYERED CYCLONIC FLOW IN THE WAKE OF THE LOW SUNDAY INTO MONDAY...WITH TEMPS ALSO TUMBLING CONSIDERING MODEL INSISTENCE OF H85 TEMPS DROPPING INTO THE SINGLE DIGITS. SPEAKING OF TEMPS...WE FEEL THAT THE GFS PROJECTION OF HIGHS IN THE 70S IS NOT ALL THAT FAR OFF...ALTHOUGH ITS WORTH NOTING THAT THE ENSEMBLE MEAN IS WARMER THAN THE OPERATIONAL GFS DURING THAT TIMEFRAME. WHILE THE ENSEMBLE AND OPERATIONAL GUIDANCE SUGGESTS THAT THE UPPER LEVEL RIDGE WILL EVENTUALLY AMPLIFY ENOUGH TO OUR WEST TO EASE THE STEEP NORTHWESTERLY FLOW ALOFT...THERE IS QUESTION AS TO HOW FAST THIS WILL OCCUR CONSIDERING HINTS OF ADDITIONAL ENERGY DIVING SOUTHEASTWARD IN THE WAKE OF THE FIRST UPPER LOW. THUS IT MAY TAKE UNTIL WEDNESDAY OR SO BEFORE NORMAL TEMPS ARE AGAIN IN THE OFFING. && .BIS WATCHES/WARNINGS/ADVISORIES... NONE. && LEBLANG/SCHULTZ
