AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BISMARCK ND
331 AM CDT MON AUG 15 2011

.SHORT TERM...TODAY THROUGH TUESDAY AFTERNOON...

FORECAST HIGHLIGHTS WILL BE ONGOING AND REDEVELOPING THUNDERSTORMS
NOW INTO TUESDAY AFTERNOON...SOME STRONG TO SEVERE. OVERALL MODELS
ARE IN DECENT AGREEMENT WITH MOST FORECAST PARAMETERS. THE
EXCEPTION IS THE AERIAL COVERAGE OF STORMS THROUGH THIS AFTERNOON.

CURRENTLY...AN AREA OF THUNDERSTORMS OVER WEST CENTRAL ND
CONTINUES TO ADVECT SOUTHEAST ALONG A WARM FRONTAL BOUNDARY.
UNCERTAIN IF THIS WILL HOLD TOGETHER AND WHETHER OR NOT IT WILL
IMPACT SOUTH CENTRAL NORTH DAKOTA. HAVE PAINTED HIGH CHANCE POPS
ALONG ITS TRAJECTORY THROUGH 12Z.

MOST MODELS INDICATE MAINLY DRY CONDITIONS LATER THIS MORNING AND
INTO THE EARLY AFTERNOON. THIS CHANGES LATE AFTERNOON WHEN THE
RIDGE AXIS PUSHES MORE EAST ALLOWING SOUTHWESTERLY FLOW ALOFT TO
DEVELOP ACROSS THE NORTHERN PLAINS. STILL...THE SFC TROUGH
LINGERS OVER EASTERN MT THROUGH 00Z TUES SO UNCERTAIN IF WE WILL
SEE CONVECTIVE DEVELOPMENT DURING THE LATER AFTERNOON HOURS AT
ALL. IF IT DOES OCCUR...WESTERN ND WILL HAVE THE BEST CHANCE
NEAR THE BOUNDARY. MAINTAINED HIGHER POPS HERE. CONTINUED
SOUTHEAST FLOW WILL BRING SFC DEWPOINTS TO NEAR 70 OVER MANY
LOCATIONS...CONTRIBUTING TO VERY UNSTABLE CONDITIONS TODAY OVER
ALL AREAS. WAA ALSO CONTINUES WITH DAYTIME HIGHS FORECAST FROM THE
80S TO LOWER 90S. HEAT INDEX VALUES WILL BE HIGHER THAN THE AIR
TEMPERATURE THANKS TO THE INCREASED HUMIDITY...BUT SHOULD REMAIN
BELOW HEAT ADVISORY CRITERIA (HI OF 100). THE DAY CREW WILL WISH
TO TAKE ANOTHER LOOK. SOUTH CENTRAL ND WILL HAVE THE BEST CHANCE
AT REACHING A HI OF 100.

CHANCES FOR THUNDERSTORMS...LIKELY SEVERE...INCREASE
SIGNIFICANTLY THIS EVENING AND THROUGH THE OVERNIGHT HOURS AS THE
SFC TROUGH PUSHES INTO WESTERN ND THIS EVENING AND INTO CENTRAL
PARTS OF THE STATE EARLY TUESDAY MORNING. THE PATH OF THE UPPER
S/WV...ACROSS NORTHERN MT AND TOWARDS SOUTH CENTRAL
CANADA...INDICATES THE HEAVIEST PRECIPITATION AND BEST CHANCES FOR
SEVERE WEATHER TO BE LOCATED OVER WEST AND NORTH CENTRAL
ND...ALTHOUGH ALL AREAS WILL BE UNDER A SEVERE WEATHER THREAT
TONIGHT.

SFC COLD FRONT RAPIDLY PUSHES FROM WEST TO EAST TUESDAY
MORNING...ENDING PRECIPITATION CHANCES FOR MOST AREAS BY MID/LATE
TUESDAY AFTERNOON. FOR THE EARLY MORNING UPDATE WE SCALED BACK
CONSIDERABLY ON POPS TUESDAY...AND WILL MAINTAIN THIS FOR THIS
PACKAGE. BREEZY WINDS OVER ALL AREAS ALONG AND BEHIND THE FRONT
TUESDAY...WITH SUSTAINED WINDS AROUND 25KTS SOUTHWEST AND 20KTS
ELSEWHERE HELPING TO ADVECT MUCH DRIER AIR INTO THE REGION ALONG
WITH COOLER TEMPERATURES.

.LONG TERM...TUESDAY NIGHT THROUGH SUNDAY NIGHT...

THE START OF THE LONG TERM PERIOD WILL START OFF ON A QUIET NOTE.
ZONAL FLOW RETURNS ACROSS THE NORTHERN PLAINS FOR TUESDAY NIGHT
THROUGH THURSDAY...WITH HIGH PRESSURE BUILDING NEAR THE SURFACE OVER
NORTH DAKOTA AND THEN MOVING SOUTHEAST. PRECIPITATION CHANCES
SEEM TO BE LIMITED AS THERE IS ONLY A WEAK WARM FRONTAL BOUNDARY
FORECAST TO MOVE NORTHEAST ACROSS THE STATE ON THURSDAY...SO KEPT
THE FORECAST DRY DURING THIS PERIOD.

MODEL SOLUTIONS DIVERGE FROM THURSDAY NIGHT ON...THE EUROPEAN
MODEL IS A BIT FASTER THAN THE GFS WITH TWO SHORTWAVES FORECAST TO
MOVE OVER NORTH DAKOTA THURSDAY NIGHT AND FRIDAY. DECIDED TO GO
WITH EUROPEAN MODEL...WHICH HAS BEEN CONSISTENT.

THE FIRST OF TWO TRAILING SHORTWAVES ASSOCIATED WITH AN UPPER LEVEL
LOW CENTERED OVER CENTRAL CANADA IS FORECAST TO TRAVERSE THE
NORTHERN EXTENT OF THE STATE THURSDAY NIGHT...THE EUROPEAN MODEL
HINTS AT THE DEVELOPMENT OF PRECIPITATION OVER SOUTHERN ALBERTA
AND MOVING EAST ACROSS SOUTHERN SASKATCHEWAN AND MANITOBA. THIS
AREA OF PRECIPITATION WILL CLIP FAR NORTHERN PORTIONS OF THE CWA.
THE SECOND OF TWO SHORTWAVES IS FORECAST TO MOVE EAST ACROSS THE
STATE ON FRIDAY. AN ASSOCIATED COLD FRONT WILL MOVE EAST OVER THE
STATE ON FRIDAY AND EARLY SATURDAY. THIS BOUNDARY COUPLED WITH
WEAK...MOIST SOUTHERLY FLOW WILL BE FAVORABLE FOR THE DEVELOPMENT
OF THUNDERSTORMS LATE FRIDAY AFTERNOON AND INTO EARLY SATURDAY.
HAVE KEPT SLIGHT CHANCES FOR THUNDERSTORMS IN THE FORECAST FOR
FRIDAY THROUGH EARLY SATURDAY.

AN UPPER LEVEL RIDGE WILL BUILD EAST ACROSS THE NORTHERN PLAINS
LATE SATURDAY AND THROUGH THE REST OF THE EXTENDED PERIOD.
PRECIPITATION CHANCES ARE FORECAST TO BE LOW...WITH ONLY A WEAK
BOUNDARY FORECAST TO TRAVERSE THE STATE AND HAVE OPTED TO KEEP THE
FORECAST DRY THROUGH THE REMAINDER OF THE EXTENDED PERIOD.

TEMPERATURES DURING THE EXTENDED PERIOD ARE FORECAST TO REMAIN
NEAR OF SLIGHTLY BELOW NORMAL FOR MID AUGUST. THE EXCEPTION WILL
BE ON THURSDAY WHERE SOUTHERLY FLOW NEAR THE SURFACE WILL WARM
THINGS UP A BIT WITH TEMPERATURES FORECAST TO BE SLIGHTLY ABOVE
NORMAL.

&&

.AVIATION...

CURRENTLY...THERE IS A LINE OF THUNDERSTORMS AND LIGHT RAIN
EXTENDING FROM NEAR SHERWOOD TO 16 MILES SOUTHEAST OF WILLISTON AND
MOVING SOUTHEAST AS OF 3 AM CDT. WITHIN THIS LINE OF
THUNDERSTORMS...THERE IS A SEVERE THUNDERSTORM 18 MILES EAST OF
WATFORD MOVING SOUTHEAST AT 25 MPH AND IS CAPABLE OF PRODUCING
WINDS IN EXCESS OF 70 MPH AND HAIL UP TO THE SIZE OF QUARTERS.
KMOT WILL BE AFFECTED BY THIS LINE OF SHOWERS AND THUNDERSTORMS
WITHIN THE HOUR...WITH FREQUENT LIGHTNING AND GUSTY WINDS BEING
THE MAIN THREATS. THIS LINE MAY AFFECT KBIS LATER THIS MORNING.
MVFR TO IFR CONDITIONS ARE POSSIBLE WITHIN THIS LINE OF
THUNDERSTORMS.

A SLOW MOVING WARM FRONT OVER EASTERN MONTANA AND WESTERN NORTH
DAKOTA AND WAA WILL CONTINUE TO BE THE MAIN FOCUS FOR THUNDERSTORM
ACTIVITY THIS MORNING ACROSS THE NORTHWEST AND CENTRAL NORTH DAKOTA.
VFR CONDITIONS WILL PREVAIL...EXCEPT IN OR IN THE VICINITY OF
THUNDERSTORMS AND SHOWERS WHERE MVFR TO IFR CONDITIONS ARE POSSIBLE.
ANOTHER ROUND OF THUNDERSTORMS ARE POSSIBLE AGAIN DURING THE
AFTERNOON AND EVENING ACROSS ALL AERODROMES.
