AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
330 PM CDT WED AUG 9 2006

.SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT...
COMPLEX PATTERN IN PLACE THIS AFTERNOON...WITH ONGOING CONVECTION IN
THE NORTHWEST AND NORTH CENTRAL...FULL SUN AND LITTLE CAP REMAINING
IN THE SOUTHWEST...AND SEVERAL BOUNDARIES FLOATING AROUND IN
BETWEEN. CURRENT VISIBLE SAT IMAGE SHOWS SOME CU DEVELOPING OVER
SOUTH CENTRAL NORTH DAKOTA. MODELS SEEM TO BE FOCUSING ON ONGOING
CONVECTION IN THE NORTH CENTRAL...SPREADING QPF SOUTH AND EAST.
STILL CONCERNED ABOUT POSSIBLE CONVECTION IN SOUTH CENTRAL NORTH
DAKOTA AS WELL. WILL KEEP A CHANCE OF THUNDER ACROSS CWA. ONE
LIMITING FACTOR FOR SEVERE WEATHER IS WEAK SHEAR. MORNING AND EARLY
AFTERNOON CONVECTION WAS IN A WEAK SHEAR ENVIRONMENT AND MARGINAL
SEVERE HAIL WAS THE RESULT UNDER THE STRONGEST CORES. SHEAR DOES
INCREASE TO AROUND 30 KT IN THE FAR SOUTH CENTRAL. THIS APPEARS TO
BE MOST LIKELY AREA FOR SEVERE WEATHER THIS AFTERNOON/EVENING.
HOWEVER AS WAS THE CASE EARLIER...CANNOT RULE OUT A PULSE SEVERE
STORM ANYWHERE THIS EVENING SO WILL GO WITH SEVERE WORDING.
CONVECTION IN THIS EVENING MAY SPREAD INTO THE FAR WEST LATE TONIGHT
AS WELL. THEN WE BASICALLY REPEAT THIS SCENARIO ON THURSDAY. COULD
NOT SEE MUCH TO CHANGE WITH PREVIOUS GRIDS...GIVEN COMPLEX PATTERN
AND LIMITED TIME DUE TO ONGOING SEVERE WEATHER...PROBABLY BEST TO
LEAVE THINGS ALONE. THEREFORE VERY FEW CHANGES...WITH HOT AND HUMID
CONDITIONS THROUGH FRIDAY...LINGERING INTO SATURDAY IN THE EAST.
WEST SHOULD COOL DOWN A BIT SATURDAY BEHIND COLD FRONT.

.LONG TERM...SUNDAY THROUGH WEDNESDAY NIGHT...
ALTHOUGH THE GFS...DGEX...AND ECWMF ALL MOVE AN UPPER LEVEL TROUGH
ACROSS THE FORECAST AREA SUNDAY AND SUNDAY NIGHT...THEY DIFFER
ENOUGH ON PLACEMENT OF THE BEST LIFTING AND AMPLITUDE OF THE TROUGH
TO CONTINUE TO HOLD BACK ON THE MENTION OF PRECIP AT THIS TIME.
RIDGING ALOFT MONDAY AND TUESDAY SHOULD KEEP THE CHANCE OF PRECIP
LOW. THE APPROACH OF ANOTHER UPPER LEVEL TROUGH COMBINED WITH THE
DEVELOPMENT OF A SURFACE LOW IN EASTERN MONTANA ON WEDNESDAY WILL
BRING ANOTHER CHANCE OF PRECIP...BUT LATE ENOUGH IN THE PERIOD THAT
WILL HOLD OFF ON MENTION FOR NOW.  TEMPS SHOULD BE SEASONABLE,

&&

.BIS WATCHES/WARNINGS/ADVISORIES...
NONE.
