Area forecast discussion, Jun 16, 2:49 PM CDT, 10 hours 19 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BISMARCK ND 249 PM CDT SAT JUN 16 2007 .SHORT TERM...TONIGHT THROUGH TUESDAY NIGHT... ACTIVE NIGHT ON TAP AS A WARM FRONT LIFTS NORTHWARD OUT OF SOUTH DAKOTA INTO OUR STATE. UNSTABLE BUT CAPPED AIR SOUTH OF THE FRONT WILL LIFT OVER THE FRONT ON THE WINGS OF A NOCTURNAL LOW LEVEL JET...THIS WILL BE THE MAIN MECHANISM FOR OUR FORECAST AREA...THUS I EXPECT MOST OF OUR THUNDERSTORMS WILL OCCUR BETWEEN 10 PM AND 10 AM SUNDAY MORNING. OTHER ACTIVITY...INITIATED OFF THE HIGHER TERRAIN OF MONTANA AND WYOMING MIGHT AFFECT OUR SOUTHWEST CORNER BY LATE AFTERNOON. A SECOND ROUND OF SEVERE WEATHER WILL DEVELOP OVER THE CENTRAL PART OF THE STATE SUNDAY AFTERNOON AS THE SURFACE LOW AND COLD FRONT PUSH THROUGH THE REGION. AFTER THAT SHOWERS AND THUNDERSHOWERS MAY LINGER IN A REGIME OF COLD UPPER LEVEL TEMPERATURES MONDAY AND TUESDAY. .LONG TERM...WEDNESDAY THROUGH SATURDAY... AS THE NIGHT SHIFT INDICATED IN THE PREVIOUS DISCUSSION...THE LAST FEW GFS AND EUROPEAN RUNS HAVE BECOME AS ONE...WITH A MUCH HIGHER DEGREE OF AGREEABILITY OVER THE EXTENDED PERIOD THAN WHAT WAS DEPICTED OVER THE PAST FEW DAYS. EXITING SHORT WAVE WEDNESDAY WILL BE REPLACED WITH NORTHWEST FLOW ALOFT OVER THE NORTHERN PLAINS AS UPPER LEVEL RIDGING TAKES PLACE OVER THE ROCKY MOUNTAIN REGION. THE UPPER LEVEL RIDGE THEN SLIDES SLOWLY EAST TOWARDS THE GREAT PLAINS THURSDAY THROUGH SATURDAY...AND WILL BRING GRADUALLY WARMER TEMPERATURES INTO THE REGION AS WE APPROACH THE WEEKEND. TOUGH CALL ON PRECIPITATION CHANCES ALL FOUR DAYS OF THE LONG TERM. RIDGE RIDER SHORT WAVES WILL BE DIFFICULT TO TIME AND PLACE...SO FELT THE BEST FORECAST WAS TO LEAVE POPS/WEATHER AS IS...LEAVING SLIGHT CHANCE POPS ALONE AS WELL AS LEAVING WEATHER OUT WHERE WE HAD DRY BEFORE. && .AVIATION... A WARM FRONT LIFTING NORTH AND AN UPPER LEVEL DISTURBANCE MOVING IN FROM MONTANA WILL BE THE FOCUS FOR THUNDERSTORMS DEVELOPING THIS EVENING WEST...ADVECTING INTO CENTRAL NORTH DAKOTA AROUND MIDNIGHT. SOME OF THESE STORMS WILL BE SEVERE. VFR CIGS AND VIS EXPECTED FOR REST OF TODAY AND THROUGH THE EARLY EVENING...WITH MVFR TO IFR CIGS AND VIS ANTICIPATED IN HEAVIER THUNDERSTORMS TONIGHT. MODELS THEN BRING IN A LARGE AREA OF LOW CIGS...AROUND 1500-2000 FT AGL...BEHIND THE CONVECTION WEST AND CENTRAL LATE TONIGHT/EARLY TOMORROW MORNING...SO HAVE TRENDED THE TAF FORECASTS IN THIS DIRECTION. MAY YET SEE AN AFTERNOON THUNDERSTORM OVER THE FAR SOUTHWEST AND SOUTH CENTRAL TODAY WITH OUTFLOW BOUNDARIES FROM THE STORMS IN SD PUSHING NORTH...AND CONVECTION OVER THE BIG HORNS OF MONTANA ADVECTING EAST-NORTHEAST. && .BIS WATCHES/WARNINGS/ADVISORIES...
